**-PART I-**

**Item 1.**&nbsp;&nbsp;&nbsp;&nbsp;***Business***

**Company Overview** 

Southwest Airlines Co. (the "Company" or "Southwest") operates Southwest Airlines, a major passenger airline that provides scheduled air transportation in the United States and near-international markets. Southwest commenced service on June 18, 1971, with three Boeing 737 aircraft serving three Texas cities: Dallas, Houston, and San Antonio. Southwest's unique route network, competitive fares, and famous Hospitality continue to make the Company an attractive choice for Customers in cities across the United States and near-international destinations. As of December 31, 2025, Southwest had a total of 803 Boeing 737 aircraft in its fleet and served 117 destinations in 42 states, the District of Columbia, the Commonwealth of Puerto Rico, and ten near-international countries: Mexico, Jamaica, The Bahamas, Aruba, Dominican Republic, Costa Rica, Belize, Cuba, the Cayman Islands, and Turks and Caicos.

**Company Initiatives**

As part of the Company's ongoing modernization efforts, the Company is executing several transformational initiatives designed to elevate the Customer Experience on its flights, improve financial performance, and drive Shareholder value, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Assigned and Extra Legroom Seating**: On January 27, 2026, Southwest began operating assigned and extra legroom seating to better align with airline passenger preferences. Passengers can now choose between a standard seat, a preferred seat near the front of the cabin, or an extra legroom seat with additional pitch.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Redesigned Boarding Model**: Southwest evolved its boarding process beginning January 27, 2026, by prioritizing Customers into boarding groups based on seat location, fare bundle, and loyalty program status, beginning with extra legroom seats in boarding groups 1 and 2.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Global Airline Partnerships**: In 2025, Southwest launched its first partnerships with international carriers to expand its network and connect Customers with more global destinations to generate additional demand for travel across the Southwest network.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Getaways by Southwest™**: Southwest launched a new in-house vacation product, Getaways by Southwest ("Getaways"), in August 2025 to offer customizable vacation packages that come with Customer-friendly policies including a generous cancellation policy and flexibility with no change fees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **24-Hour Operations**: In 2025, Southwest added 24-hour operation capabilities with the introduction of overnight (i.e., redeye) flights in key markets to maximize aircraft utilization. The Company intends to expand redeye flights to additional markets in 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Marketing & Distribution Evolution**: In order to attract new Customers and reach them where they are performing travel searches today, Southwest expanded into new channels such as Expedia, Priceline, Google Flights, Kayak, and Skyscanner to broaden its Customer base and begin to engage them in its loyalty program.

**Company Operations**

**Route Structure**

Southwest primarily provides "point-to-point" service, rather than the "hub-and-spoke" service provided by most major U.S. airlines. A point-to-point system enables airlines to connect directly to destinations without providing connecting service. By contrast, the hub-and-spoke system concentrates most of an airline's operations at a limited number of central hub cities and serves most other destinations in the system by providing one-stop or connecting service through a hub. By not concentrating operations exclusively through one or more central transfer points,

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

Southwest's route structure has allowed for more direct nonstop routing than a traditional hub-and-spoke service. To provide greater connectivity and support operational reliability and recoverability, in recent years the Company has increasingly focused on designing its network around core stations. By blending intentional connectivity offered by hub-and-spoke models and point-to-point nonstops, the Company is able to capture nonstop demand and provide reliable one-stop itinerary options.

Southwest's unique route network has also enabled it to provide its markets with frequent, conveniently timed flights and competitive fares. For example, Southwest offers up to 12 weekday roundtrips between Dallas Love Field and Houston Hobby, 12 weekday roundtrips between Sacramento and San Diego, 12 weekday roundtrips between San Diego and San Jose, 12 weekday round trips between Las Vegas and San Diego, and 11 weekday roundtrips between Las Vegas and Sacramento. Southwest complements its high-frequency short-haul routes with mid-range and long-haul nonstop service, including flights between Hawaii and California, Las Vegas, and Phoenix, and between markets such as Las Vegas and Washington Reagan, Los Angeles and Nashville, New York LaGuardia and Houston, Los Angeles and Baltimore, Oakland and Houston, and San Diego and Baltimore. As the domestic travel market has matured and structural changes have reduced the demand for short-haul travel, the Company has increased its proportion of longer-haul flights. Further, the Company introduced 24-hour operation capabilities in 2025 with the commencement of redeye flights. Southwest now offers over 50 peak-day redeye flights during peak periods and includes flights across the continental United States and from Hawaii to the U.S. mainland, with plans to offer flights from Alaska to the U.S. mainland in 2026.

The table below sets forth data regarding the Company's nonstop service, aircraft stage length, and trip duration over the last three years:

---

| | | | |
|:---|:---|:---|:---|
| | **Year ended December 31,** | **Year ended December 31,** | **Year ended December 31,** |
| | **2025** | **2024** | **2023** |
| Percentage of Customers flying nonstop | 74% | 74% | 73% |
| Nonstop city pairs | 871 | 850 | 805 |
| Average stage length (miles) | 780 | 763 | 730 |
| Average trip duration (hours) | 2.1 | 2.0 | 2.0 |

---

The Company continually works to better optimize its route network and schedule through the adjustment of flights in its existing markets and the addition of new markets and itineraries, while also pruning less profitable flights from its schedule. During 2025, the Company focused on expanding its network, announcing service at five new locations beginning in 2026, including Cyril E. King International Airport in St. Thomas; McGhee Tyson Airport in Knoxville, Tennessee; Ted Stevens Anchorage International Airport in Alaska; Charles M. Schulz Sonoma County Airport in Santa Rosa, California; and Princess Juliana International Airport in St. Maarten. Additionally, the Company launched partnerships with six international airlines to provide Customers access to more global destinations. The Company's partnerships with international carriers have improved its international connectivity with its domestic network. The Company also sought to enhance connectivity and better optimize its network to match capacity to demand and adjust for Customer travel patterns by reducing short-haul trips, redistributing resources to longer-haul trips in more profitable markets, and reducing flying on weekdays and at off-peak times with lower travel demand. In response to market conditions, the Company redeployed underperforming capacity by significantly reducing service at Atlanta and Fort Lauderdale, while expanding service at Nashville and San Diego. The Company is continuing to improve the connectivity and efficiency of its network through redesigns in smaller cities and the introduction of redeye flying. The Company's unique route network allows for these adjustments without structurally disrupting its airports in core markets and other large cities.

**Cost Structure**

***General***

A key component of the Company's business strategy is its focus on cost discipline and charging competitive fares. The Company's low-cost strategy includes, among other elements, the Company's route structure, which includes

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

service to and from many secondary or downtown airports such as Dallas Love Field, Houston Hobby, Chicago Midway, Baltimore-Washington International, Burbank, Manchester, Oakland, San Jose, and Providence. These conveniently located airports are typically less congested than other airlines' hub airports, which has contributed to Southwest's ability to achieve high asset utilization because aircraft can be scheduled to minimize the amount of time they are on the ground. This, in turn, has reduced the number of aircraft and gate facilities that would otherwise be required and is designed to allow for higher Employee productivity over a long period of time. Additionally, Southwest's use of a single aircraft type, the Boeing 737, allows for simplified scheduling, maintenance, flight operations, safety management, and training activities. Given ever-evolving travel patterns and labor market challenges, the Company continues to focus on better optimizing its route network, improving operational efficiency and reliability, and increasing Employee productivity. In 2025, the Company increased asset utilization through its introduction of redeye flights and its initiatives to decrease the amount of time it takes to turn an aircraft (the time needed to unload Passengers from an arriving flight and load Passengers on the same aircraft for its subsequent flight). Such investments included moving to a digital (i.e., paperless) process, improving communication tools for Employees, and launching better visual and real-time information to assist both Customers and Employees. Key initiatives have been fully implemented and are designed to lower unit costs, as the Company is expected to be able to, at a minimum, generate the same number of available seat miles ("ASMs") with fewer aircraft. In addition, the Company continues to target other cost savings initiatives, including capitalizing on identified supply chain opportunities and improving its corporate efficiency through automation and better allocation of resources.

***Fuel and Fleet***

Fuel and oil expense can be extremely volatile and unpredictable, and even a small change in market fuel prices can significantly affect profitability. Although the Company's jet fuel prices per gallon were generally lower in 2025, as compared with 2024, Fuel and oil expense remained the Company's second largest operating cost category for 2025. As evidenced by the table below, energy prices can fluctuate significantly in a relatively short amount of time. Based on higher fuel hedging premium costs over time and other factors, during second quarter 2025, the Company terminated its remaining portfolio of fuel hedging contracts, which were scheduled to settle through 2027, to effectively close its fuel hedging portfolio and program. The risks associated with high and/or volatile fuel prices are discussed in more detail below under "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations," and Note 10 to the Consolidated Financial Statements. The table below shows the Company's average cost of jet fuel inclusive of fuel taxes and fuel hedging impacts, for each year beginning in 2011 and during each quarter of 2025.

As of December 31, 2025, the Company had 300 Boeing 737-8 ("-8") aircraft in its fleet. In the second and fourth quarters of 2025, the Company entered into supplemental agreements (the "Supplements") to its purchase agreement with The Boeing Company ("Boeing") relating to the Company's purchase of -8 and Boeing 737-7 ("-7", and, together with -8, the "MAX aircraft"). Pursuant to the Supplements, the Company amended its order book delivery schedule to better allocate aircraft deliveries to the Company's network and capacity plans, in part due to ongoing aircraft delivery delays. The Supplements also include certain confidential credits and other concessions provided to the Company by Boeing. The Company held 152 remaining MAX options as of December 31, 2025, in addition to 465 firm orders of MAX aircraft to be delivered through 2031. The Company retains significant flexibility to manage its fleet size, including opportunities to accelerate fleet modernization efforts (e.g., through accelerated retirements of the Company's Boeing 737-700 ("-700") aircraft) if growth opportunities do not materialize. The Company plans to continue to pursue opportunities to take advantage of favorable market conditions through the sale of certain aircraft, with the intention of replacing most, if not all, of such aircraft with new aircraft. The Company expects to use the proceeds of its fleet transactions to support its capital allocation strategy. For further information regarding the Company's aircraft contractual order book see "Properties" and "Management's Discussion and Analysis of Financial Condition and Results of Operations." The delivery schedule for the -7 is dependent on the Federal Aviation Administration ("FAA") issuing required certifications and approvals to Boeing and the Company. The FAA will ultimately determine the timing of the -7 certification and entry into service, and the Company therefore offers no assurances that current estimations and timelines are correct.

The Company's focus on controlling costs also includes a continued commitment to pursuing, implementing, and enhancing initiatives to reduce fuel consumption and improve fuel efficiency (ASMs per fuel gallon consumed). The Company focuses on minimizing fuel consumption and improving fuel efficiency through fleet modernization and other fuel initiatives. The Company's fuel efficiency was aided in 2025, as compared with 2024, by the addition of 55 -8 aircraft to its fleet and by the retirement of 48 of its oldest, least fuel-efficient -700 aircraft and the retirement of seven Boeing 737-800 ("-800") aircraft. The table below sets forth the Company's ASMs produced per fuel gallon consumed (fuel-efficiency) over the last five years:

***Labor***

Salaries, wages, and benefits expense constituted approximately 46.9 percent of the Company's operating expenses in 2025 and was the Company's largest operating cost category. Increased labor costs from ratified contracts and rate inflation have negatively impacted not only the Company's cost structure but also the broader airline industry's costs. During 2025, active full-time equivalent headcount increased by 340, or 0.5 percent, compared with year-end 2024. The Company implemented a reduction in its workforce in February 2025 designed to reduce operating costs, increase efficiency, and create a leaner and more agile organization as part of its transformational plan. The reduction in workforce provided for the reduction of approximately 1,750 Employee roles, or 15 percent of corporate positions. For 2026, the Company plans to keep corporate headcount expense flat to 2025 levels and will focus on operational efficiencies within frontline teams. The Company's labor costs, and risks associated therewith, are discussed in more detail below under "Business—Employees," "Risk Factors," and "Management's Discussion and Analysis of Financial Condition and Results of Operations."

**Fare Structure**

***General***

Southwest's fare structure features competitive fares and product benefits, including fares with different levels of restrictions. In 2025, Southwest introduced a new, "Basic" fare on its lowest priced tickets, replacing Southwest's "Wanna Get Away<sup>®</sup>" offering. Southwest also introduced new fare products including "Choice," "Choice Preferred," and "Choice Extra," replacing Southwest's previous "Wanna Get Away Plus<sup>®</sup>," "Anytime," and "Business Select<sup>®</sup>" offerings. For travel on or before January 26, 2026, fare bundles included open seating. For travel on or after January 27, 2026, fare bundles include assigned seating.

Southwest's four major fare product categories provide Customers options when choosing a fare. For flights booked and ticketed or changed on or after May 28, 2025, Southwest introduced bag fees for most fare products. However, the Company continues to offer two free checked bags to Rapid Rewards<sup>®</sup> A-List Preferred Members and Customers traveling on Choice Extra fares and offers one free checked bag to A-List Members and co-brand Cardmembers under its credit card program (weight and size limitations apply). Southwest does not charge fees for cancellations or changes to flight reservations for Choice, Choice Preferred, or Choice Extra fares, although fare differences may apply. For the Basic fare bundle, Southwest does not charge fees for cancellations, and any changes to flight reservations require an upgrade to the Choice fare.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "Basic" fares are generally the lowest fares and are often subject to advance purchase requirements. They are non-refundable and non-changeable except as allowed by Southwest's 24-hour cancellation policy or a fare upgrade to Choice, Choice Preferred, or Choice Extra. If a Customer cancels a Basic fare ticket at least 10 minutes prior to the flight's original departure time, the Customer may be eligible for a flight credit for the fare paid for unused travel by the Customer ("flight credit"). Flight credits originating from a Basic fare purchase will expire six months from ticketing date. Customers purchasing a Basic fare are assigned a standard seat at check-in or may purchase a standard, preferred, or extra legroom seat, if available. A-List or A-List Preferred Members under the Company's Rapid Rewards loyalty program who purchase a Basic fare are eligible for a same-day standby listing, free of airline charges, if there is another flight that departs on the same day as the original flight and is between the same origin and destination airports, but the Customer is required to pay any additional government taxes and fees associated with voluntary changes in their itinerary. Under Southwest's Rapid Rewards loyalty program, Basic fares earn two Rapid Rewards points for each dollar spent on the base fare. The Company's loyalty program is discussed below under "Rapid Rewards Loyalty Program."

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "Choice" fares may be subject to advance purchase requirements. They are non-refundable, but, subject to Southwest's No-Show Policy, Customers are eligible for a Transferable Flight Credit™ if they cancel a Choice fare ticket. Transferable Flight Credits enable Customers to transfer an eligible unused flight credit to another traveler for future travel on Southwest. Both travelers must be Rapid Rewards Members and only one transfer is permitted. Transferable Flight Credits issued for Choice fare tickets purchased on or after May 28, 2025, will expire one year from the date of booking and ticketing. For bookings through a Southwest Business (corporate travel) channel, a transfer may only be made to an employee of the same organization. Choice fares earn six Rapid Rewards points for each dollar spent on the base fare. Customers purchasing a Choice fare receive the choice of any standard seat at booking or may purchase a preferred or extra legroom seat, if available. Choice fares also enable a same-day confirmed change, free of airline charges, if there is an open seat on another flight that departs on the same day as the original flight and is between the same origin and destination airports, but the Customer is required to pay any additional government taxes and fees associated with voluntary changes in their itinerary (refunds may be provided). If there is no open seat on this different flight, a traveler may request to be added to the standby list for that flight.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "Choice Preferred" fares may be subject to advance purchase requirements. They are refundable if canceled, subject to Southwest's No-Show Policy, or a Transferable Flight Credit may be applied towards future travel on Southwest. If this fare is purchased with non-refundable flight credit, then the resulting flight credit will be non-refundable if travel is canceled. Transferable Flight Credits issued for Choice Preferred fare tickets purchased on or after May 28, 2025, will expire one year from the date of booking and ticketing. Choice Preferred fares earn 10 Rapid Rewards points for each dollar spent on the base fare. Customers purchasing a Choice Preferred fare receive the choice of any standard or preferred seat at booking or may purchase an extra legroom seat, if available. Additionally, Choice Preferred fares receive Priority Lane and Express Lane access through check-in and security lines where available. Further, Choice Preferred fares receive all of the benefits of Choice fares, including a Transferable Flight Credit and same-day confirmed changes and standby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "Choice Extra" fares may be subject to advance purchase requirements. They are refundable if canceled, subject to Southwest's No-Show Policy, or a Transferable Flight Credit may be applied towards future travel on Southwest. If this fare is purchased with non-refundable flight credit, then the resulting Transferable Flight Credit will be non-refundable if travel is canceled. Transferable Flight Credits issued for Choice Extra fare tickets purchased on or after May 28, 2025, will expire one year from the date of booking and ticketing. Customers purchasing a Choice Extra fare receive the choice of any seat at booking, including a preferred or extra legroom seat, if available. Choice Extra fares include additional perks such as two free checked bags, early boarding (in groups 1 and 2), and 14 Rapid Rewards points per dollar spent on the base fare, the highest loyalty point multiplier of all Southwest fare products. Choice Extra fares also receive one complimentary premium beverage coupon for the day of travel on flights 251 miles or more (Customers must be of legal drinking age to drink alcoholic beverages) and all of the benefits of Choice Preferred fares, including Priority Lane and Express Lane access through check-in and security lines where available, a Transferable Flight Credit, and same-day confirmed changes and standby.

Southwest's No-Show Policy applies if a Customer does not change or cancel a flight segment at least 10 minutes prior to scheduled departure and the Customer does not travel on the scheduled flight. In such event, subject to certain exceptions, all unflown segments associated with the reservation will be canceled, and (i) with respect to a Basic or Choice reservation, the fare paid for unused travel and any points used for booking the reservation will be forfeited, along with any taxes and fees associated with a reward travel reservation; and (ii) with respect to a Choice Preferred or Choice Extra reservation, the value of the ticket will be refunded in the form of a Transferable Flight Credit and any points used for booking the reservation will be redeposited to the Customer's Rapid Rewards account, and any taxes and fees associated with a reward travel reservation will be converted into a Transferable Flight Credit for future use. Transferable Flight Credits created from reservations booked and ticketed and/or voluntarily changed on or after May 28, 2025 have a specified expiration date. All travel must be completed by the expiration date.

***Ancillary Services***

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

The Company offers ancillary services such as Priority Boarding and transportation of pets and unaccompanied minors in accordance with Southwest's respective policies.

Priority Boarding allows Customers to upgrade their boarding group ahead of Group 1. This upgrade is available for purchase starting 24 hours before departure and can be bought up to 60 minutes prior to departure, if available. Priority Boarding is non-refundable, priced per flight, per Customer, and sold by segment for connecting itineraries.

Priority Boarding replaced Southwest's legacy ancillary services: EarlyBird Check-In<sup>®</sup>, which provided Customers with automatic check-in and an assigned boarding position before general boarding positions became available, and Upgraded Boarding, which allowed a Customer to pay for an open priority boarding position in the first 15 positions in its "A" boarding group. Early Bird Check-In and Upgraded Boarding were available for flights that departed on or before January 26, 2026.

Southwest's Pet Policy provides Customers an opportunity to travel with a small cat or dog in the aircraft cabin on domestic flights. Southwest also has an unaccompanied minor travel policy, with pricing to address the administrative costs and the extra care necessary to safely transport these Customers.

**Rapid Rewards Loyalty Program**

Southwest's Rapid Rewards loyalty program enables program members ("Members") to earn points for every dollar spent on Southwest base fares, also generally including purchases paid with LUV Vouchers, gift cards, or flight credits. The amount of points earned under the program is based on the base fare and fare class purchased, with higher fare products (e.g., Choice Extra) earning more points than lower fare products (e.g., Basic). As discussed above under "Fare Structure – General," each fare class is associated with a points earning multiplier, and points for flights are calculated by multiplying the base fare for the flight by the fare class multiplier. The amount of points required to be redeemed for a flight is based on the base fare and a multiplier. In 2025, the Company better aligned earn rates to fare type and introduced variable redemption rates across higher-demand and lower-demand flights as part of its transformational plan. Under the program, (i) Members are able to redeem their points for every available seat, every day, on every flight, with no blackout dates; and (ii) points do not expire.

Under the program, Members continue to accumulate points until the time they decide to redeem them. As a result, the program provides Members significant flexibility and options for earning and redeeming rewards. For example, Members can earn more points (and achieve tier status such as A-List, A-List Preferred, or a Companion Pass<sup>®</sup> faster) by purchasing higher fare tickets. Members also have significant flexibility in redeeming points, such as the opportunity to take advantage of many fare sales, requiring fewer points, or by redeeming points for close-in bookings, if seats are still available for sale. Members can also earn points through qualifying purchases with Rapid Rewards Partners (which include, for example, car rental agencies, hotels, and restaurants), as well as by using Southwest's co-branded Chase<sup>®</sup> Visa credit cards or Southwest Airlines Rapid Rewards Debit Card. In addition to earning points for revenue flights and qualifying purchases with Rapid Rewards Partners, Members also have the ability to purchase, gift, and transfer points, as well as the ability to donate points to selected charities. Members are also able to pay for their flights with a combination of cash and Rapid Rewards points—starting with as few as 1,000 points. The cash portion of a cash plus points booking earns Rapid Rewards points, Rapid Rewards Business points, tier qualifying points for A-List or A-List Preferred status, and Companion Pass qualifying points.

Southwest's Rapid Rewards loyalty program features tier status and Companion Pass programs for the most active Members, including "A-List" and "A-List Preferred" status. A Member who flies 20 qualifying one-way flight segments booked through Southwest or earns 35,000 tier qualifying points per calendar year will qualify for A-List status. A Member who flies 40 qualifying one-way flights booked through Southwest or earns 70,000 tier qualifying points per calendar year will qualify for A-List Preferred status. The Member will maintain A-List or A-List Preferred status for the remainder of the calendar year in which the status is earned and for the entire calendar year immediately following. Both A-List and A-List Preferred Members enjoy benefits such as free Wi-Fi sponsored by T-Mobile, priority check-in and security lane access, where available, dedicated phone lines, standby priority, and

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

an earnings bonus on eligible revenue flights (25 percent for A-List and 100 percent for A-List Preferred). In addition, A-List Preferred Members enjoy up to two complimentary premium drinks per flight on flights traveling 251 miles or more, added directly to their mobile boarding passes. If an A-List or A-List Preferred Member's plans change, subject to Southwest's No Show Policy, they are entitled to a same-day standby listing, free of airline charges, if there is another flight that departs on the same day as the original flight and is between the same origin and destination airports, but the Customer is required to pay any additional government taxes and fees associated with voluntary changes in their itinerary. A-List Preferred and A-List Members are not eligible for free same-day change unless the Member purchases a qualifying fare. Another feature of the Rapid Rewards loyalty program is the Companion Pass. Members who fly 100 qualifying one-way flights or earn 135,000 qualifying points in a calendar year automatically receive a Companion Pass, which provides for unlimited travel for the designated Companion free of charges (other than taxes and fees). The Companion Pass is valid for the remainder of the calendar year in which status is earned and for the following full calendar year to any destination available on Southwest for a designated Companion of the qualifying Member. The Member and designated Companion must travel together on the same flight.

Southwest updated its Tier Benefits in 2025, giving A-List and A-List Preferred Members and Cardmembers more value through assigned seats, extra legroom seating, and Southwest's baggage policy. A-List Preferred Members receive their first and second checked bags for free, and A-List Members and Rapid Rewards Credit Cardmembers receive their first checked bag for free. When available, Members who attain A-List Preferred status receive the ability to choose an extra legroom seat, preferred seat, or standard seat at the time of booking when purchasing any fare product for themselves and up to eight additional passengers on the same reservation as the A-List Preferred Member. When available, A-List Members receive the ability to choose a preferred seat or standard seat at the time of booking when purchasing any fare product and may also upgrade to an extra legroom seat within 48 hours prior to flight departure for themselves and up to eight additional passengers on the same reservation as the A-List Member. Additionally, Cardmembers are eligible to select seats within 48 hours of departure on any fare, and certain Cardmembers are eligible to select seats upon booking any fare.

The Company also began offering the Southwest Airlines Rapid Rewards Debit Card, a Visa debit card issued by Sunrise Banks N.A., in November 2025. Debit cardholders can earn Rapid Rewards points on everyday purchases. The Company is exploring potential additional opportunities for Rapid Rewards Members to earn and redeem points.

The Company also gives businesses the ability to earn Rapid Rewards points through Rapid Rewards Business. By joining Rapid Rewards Business, companies earn Rapid Rewards points that can be applied toward travel on the company's behalf, while travelers who are Rapid Rewards Members also earn Rapid Rewards points in their personal accounts. Rapid Rewards Business accounts generally have the same opportunities and benefits to earn and redeem points as individual Member accounts.

Southwest's Rapid Rewards loyalty program has been designed to drive more revenue by (i) bringing in new Customers, including new Members, as well as new holders of Southwest's co-branded Chase Visa credit cards and Southwest Airlines Rapid Rewards Debit Card; (ii) increasing business from existing Customers; and (iii) strengthening the Company's Rapid Rewards hotel, rental car, credit card, debit card, and other partnerships. The table below shows the number of flight awards redeemed for each of the past three years.

---

| | | | |
|:---|:---|:---|:---|
| | **Year ended December 31,** | **Year ended December 31,** | **Year ended December 31,** |
| | **2025** | **2024** | **2023** |
| Flight awards redeemed (millions) | 9.1 | 10.1 | 10.9 |

---

For 2025, 2024, and 2023, Customer redemption of flight awards accounted for approximately 13.7 percent, 14.7 percent, and 16.3 percent of revenue passenger miles flown, respectively. The Company's accounting policies with respect to its loyalty programs are discussed in more detail in Note 1 to the Consolidated Financial Statements.

**Investments in Customer Experience**

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

In recent years, the Company has sought to modernize and transform the Customer Experience. As part of the evolution, Southwest began offering free Wi-Fi for all Rapid Rewards Members through a sponsorship with T-Mobile in October 2025. Additionally, Southwest offers a comprehensive inflight entertainment platform that includes more than 115 free movies-on-demand each month, live and on-demand television (where available), a flight tracker, and additional curated content, as well as a variety of premium snacks and coffee.

The Company has further enhanced Customers' cabin experience through the introduction of in-seat power, larger overhead bins, and a refreshed cabin design. The Company began taking delivery of MAX aircraft with the latest-generation of onboard USB-A and USB-C power ports in 2023 to allow Customers to charge personal devices at every seat and completed installation of in-seat power ports on all previously delivered MAX aircraft as of July 2025. Further, the Company had received 146 new -8 aircraft and retrofitted 39 -8 aircraft and 15 -800 aircraft with larger overhead bin space as of December 31, 2025. All of the Company's new -8 aircraft deliveries will come equipped with larger overhead bin space, and the Company plans to retrofit the remainder of its -8 and -800 fleets with larger overhead bins by the end of 2026. The larger overhead bins provide easier access to carryon items and are expected to result in better operational metrics, fewer gate checked bags, and an improved Customer Experience. Additionally, the Company received its first deliveries of aircraft with new, more comfortable RECARO seats in 2025 as part of its cabin design refresh.

The Company has enabled new self-service capabilities to elevate ease of doing business with Southwest. The Company launched its participation in TSA PreCheck<sup>®</sup> Touchless ID in 2025 so that Rapid Rewards Members enrolled in TSA PreCheck may opt in on the Southwest app. Additionally, Customers can now digitally check and pay for up to three bags prior to arriving at the airport through the Southwest app.

Beginning January 27, 2026, the Company introduced an assigned seating model to provide Customers enhanced optionality based on Customer feedback, travel patterns, and preferences. Customers may now select their seats from standard seat, preferred seat, or extra legroom seat options. In connection with its move to assigned seating, the Company also redesigned its boarding model based on seat location, fare bundle, and loyalty program status. Generally, Customers flying on a Choice Extra fare or with A-List Preferred Member status board in groups one or two, Choice Preferred fares board groups three through five, Choice fares board groups five through eight, and Basic fares are the last to board. A-List Members generally board in groups one through five, and Rapid Rewards Credit Cardmembers booking Basic or Choice fares may generally board in group five or sooner. Customers may also purchase Priority Boarding 24 hours prior to departure to be among the first to board.

**Global Airline Partnerships**

In 2025, Southwest launched its first partnerships with international carriers to expand its network and connect Customers with more global destinations with the goal of generating additional demand for travel across the Southwest network. The Company now has interline partnerships with Icelandair, China Airlines, EVA Air, Philippine Airlines, Condor, and Turkish Airlines to provide transoceanic connectivity through Baltimore-Washington, Denver, Nashville, Orlando, Pittsburgh, Raleigh-Durham, Honolulu, Los Angeles, Seattle, San Francisco, Ontario, and Chicago. The Company is exploring opportunities to add additional gateways with these partners in 2026. The Company additionally intends to continue to pursue partnerships with other airlines to further expand the reach of the Company's network, with a goal to add additional partners during 2026. The Company also launched a partnership with Hahnair in 2025 to expand its global ticketing reach to markets outside of the United States and enable international Customers to purchase Southwest itineraries in their local currency.

**Getaways by Southwest** 

In August 2025, the Company launched Getaways, a new in-house vacation package product, replacing the outsourced product Southwest historically offered. Southwest has over 25 direct hotel partnerships in over 30 destinations through Getaways and is exploring opportunities to introduce more hotel partnerships in 2026. Customers booking a vacation through Getaways can check two bags for free and earn five Rapid Rewards points

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

per dollar spent on bookings. Customers can also cancel their packages and receive vacation travel credits, valid for 18 months, that can be applied toward a future Getaway, and Customers have the flexibility to make changes to their Getaway package without paying a change fee. The Company expects Getaways to appeal directly to its broad existing Customer base with an enhanced offering that includes both lodging and excursions, designed to drive growth with leisure travelers and grow higher-margin revenues.

**Distribution and Marketing Approach**

The Company primarily offers its fare products directly to Customers through its Internet website, Southwest.com<sup>®</sup>, and the Southwest App. For the years ended December 31, 2025, and December 31, 2024, approximately 78 percent and 81 percent, respectively, of the Company's Passenger revenues originated from Southwest.com or the Southwest App (including revenues from SWABIZ<sup>®</sup>, the Company's online booking tool designed for business Customers who prefer a self-service and low-cost solution for booking their air travel on Southwest). The year-over-year decrease primarily resulted from an increase in bookings through online travel agencies in 2025.

The Company has recently focused on attracting new and less frequent Customers, in part, through new distribution channels and the launching of new ad campaigns. The Company has expanded its distribution channels through partnerships with flight meta search engines, including Google Flights, Kayak, Skyscanner, and, in 2025, online travel agencies Expedia and Priceline, to increase visibility and drive traffic for bookings to Southwest.com. In connection with its international partnerships, the Company also expanded its distribution in 2025 to allow (i) other partner airlines to sell tickets which include Southwest segments and (ii) third party agencies associated with partner airlines to sell tickets for Southwest itineraries in local, foreign currency.

In June 2025, the Company launched "Are You Sitting Down?": a marketing campaign to build awareness and excitement for the Company's new assigned seating policy and extra legroom seats options. The campaign highlights choice and greater control of the travel experience for the Company's Customers delivered with the Company's unique sense of humor. Additionally, in August 2025, the Company launched a "Vacation is More Fun When it's Flexible!" campaign touting its new in-house vacation product, Getaways. The Company has also expanded its promotional text message and push notification campaigns, enhanced its Rapid Rewards acquisition programs, and improved co-brand credit card acquisition strategies to strengthen Customer engagement and loyalty.

The Company continues to invest in technology to support artificial intelligence ("AI")-based marketing efforts. In 2025, the Company undertook broad search engine and generative AI engine optimization efforts across its mobile app, landing pages, and destination, origination, and market specific pages. Generative AI copy testing has been introduced to refine marketing messages and optimize conversion rates, contributing to increased sales per marketing effort.

**Digital Hospitality**

The Company remains committed to strengthening its Customer Service by enhancing digital Hospitality capabilities. The Company continues to execute a multi-year digital service modernization program designed to, among other things, improve Customer Service while lowering operating costs. Key focus areas of the program include contact center service modernization, airport service modernization, Customer Service communications, and disruptions management.

In 2025, the Company implemented digital enhancements to empower Customer self-service and improve operational efficiency. Key updates included digital pre-paid checked baggage fee collection, tools to improve the check-in and boarding processes in conjunction with assigned seating, and the launch of a new security processing capability, TSA Precheck Touchless ID, at multiple airports in partnership with the Transportation Security Administration ("TSA"). The Company added additional Customer Service capabilities, including self-service assigned seating management, automated messaging directing eligible Customers to check carryon bags prior to arriving at the jet bridge, and improved account assistance tools aimed at reducing contact center volume and

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

increasing account protection through multi-factor authentication. The Company also launched a simplified Rapid Rewards enrollment process and introduced free Wi-Fi sponsored by T-Mobile for Rapid Rewards Members.

The Company advanced several initiatives during 2025 to enhance its digital channels and improve commercial performance. Southwest continued modernizing its core digital platforms with the launch of a fully responsive web homepage and an improved mobile app. Southwest redesigned its mobile app homepage, upcoming trips view, offers experience, and navigation structure. Southwest's app now provides enhanced mobile boarding passes and information on inflight food, beverage, entertainment, and connectivity options. The Company also deployed a newly redesigned Low Fare Calendar experience, making it easier to discover low fares on desktop and mobile experiences, and enabled International Document Scanning for international travelers to validate supported travel documents. Improvements to these digital platforms underscore the Company's commitment to meeting various Customer needs and growing its market presence.

**Southwest Business**<sup>®</sup> **Initiatives**

In addition to improvements in the Company's consumer-direct Southwest.com channel of distribution and new distribution partnerships, in recent years the Company has taken significant action, including investments in Employees, processes, and technology, in order to grow its corporate travel business with the goal of making it easier for corporate travel Customers and travel management companies to do business with Southwest. The Company employs a multi-channel distribution strategy for its corporate business travel, offering the ability for business travelers and travel decision makers to book Southwest fares within all major Global Distribution System platforms via Amadeus, Travelport, and Sabre channels, through third-party partners directly connected to the Company's host reservation system, or through the Company's free corporate online booking tool, SWABIZ<sup>®</sup>.

The Company utilizes Airlines Reporting Corporation to implement industry standard processes to handle the settlement of tickets booked through Travelport, Amadeus, and Sabre channels. The Company also utilizes ATPCO Routehappy to provide detailed product information that supports robust shopping and selling processes in third-party booking channels.

The Company offers Southwest Business Meetings, a product for its corporate Customers that is designed to make it easier for meeting planners to manage travel on Southwest by streamlining the process to book group travel for meetings and conventions. In 2025, the Company launched Southwest Groups, a redefined booking and travel management tool for travel decision makers specializing in group travel. The Company also offers Southwest Business Assist™, a travel portal that enables corporate travel buyers, travel decision makers, and travel management companies to better manage their business travel on Southwest using dashboards, reports, automated processing of travel benefits, and Customer Service. The on-demand self-service tool provides access to real-time information and reporting. Southwest Business has also continued to invest in and enhance SWABIZ with mobile capabilities. SWABIZ is designed for business Customers who prefer a self-service and low-cost solution for booking their air travel on Southwest. The site also facilitates car and hotel bookings and offers a suite of reports for travel managers. The Company has additionally developed a data-sharing application programming interface channel, Southwest Business TravelTrack<sup>®</sup>, that provides business travel Customers and third-party partners more visibility into the business they do with Southwest.

**Technology Initiatives**

The Company is focused on the prioritization and execution of its technology investments through an evolving multi-year plan, with the goal of developing stronger, more adaptable, more efficient, more secure, and more reliable technology systems to support the Company's strategic priorities. The Company has committed, and plans to continue to commit, significant resources to technology improvements in support of its ongoing operations and initiatives. During 2025, among other things, the Company (i) developed new technology to enable assigned seating, extra legroom seating, and enhanced boarding processes; (ii) introduced free Wi-Fi sponsored by T-Mobile for all Rapid Rewards Members; (iii) further expanded its distribution channels via partnerships with Expedia and

Priceline; (iv) launched a digital pre-paid bags application; (v) enhanced and modernized chat functions and AI-based support for service replies; (vi) enabled interline partnerships; (vii) replaced its legacy flow management system in support of the Company's continued investment in operational excellence; and (viii) modernized operational systems that enabled redeye flying.

The Company continues to invest significantly in technology resources including, among others, the Company's systems related to (i) inflight Wi-Fi capabilities; (ii) digital Customer Service modernization; (iii) enhancing the Customer Experience and premium product offerings; (iv) industry standard interline and codeshare capabilities; (v) further scaling 24-hour operations; (vi) flight schedule management designed to improve operating efficiency and fleet utilization; (vii) aircraft turn capabilities designed to improve operating efficiency; (vii) crew mobility and scheduling capabilities designed to improve operating quality and resiliency; (viii) further enhancing the Company's vacation packages with Getaways; (ix) modernization of the Company's financial management systems; (x) modernization of the Company's data and processing AI capabilities; and (xi) further modernization of technology infrastructure and cybersecurity. The Company's strategic initiatives represent significant undertakings by the Company and continue to require the incorporation of new technologies and procedures for a seamless transition.

**Environmental Sustainability**

Over the years, the Company has undertaken a number of initiatives that have a direct impact on its fuel conservation and emissions-related reduction efforts, including the introduction of the MAX aircraft into the Company's fleet, which is more fuel-efficient and releases fewer CO₂ emissions per ASM than the Company's previous generation of 737 aircraft.

The Company participates in Required Navigation Performance ("RNP") operations as part of the FAA's Performance Based Navigation program. RNP combines the capabilities of advanced aircraft avionics, satellite navigation (instead of less efficient ground-based navigation), and new flight procedures to enhance navigational and operational capabilities, improve fuel efficiency, and minimize greenhouse gas ("GHG") emissions. RNP approaches, which are published by the FAA, are currently available at a limited number of the airports Southwest serves, but the Company continues to work with the FAA to develop and seek more use of RNP approaches and to evolve air traffic control rules to support greater utilization of RNP.

The Company has previously announced certain near- and long-term environmental sustainability goals and has undertaken related initiatives. These goals and initiatives remain subject to ongoing evaluation and may change as market, regulatory, or technological conditions evolve. In addition, the Company's ability to make progress towards its sustainability goals and the advancement of related initiatives will depend on factors outside of its control, including, among other things, the future availability and cost of sustainable aviation fuel ("SAF"), advancements in fuel-efficient technology, government support, and other operational or technological innovations. While the Company believes that its voluntary disclosures regarding environmental, social, and governance matters are responsive to various areas of investor interest, the Company believes that certain of these disclosures do not currently address matters that are material to the Company's operations, strategy, financial condition, or financial results, although this view may change in the future based on new information that could materially alter the estimates, assumptions, or timelines used to create these disclosures. Given the estimates, assumptions, and timelines used to create such disclosures, the materiality of these disclosures is inherently difficult to assess in advance.

**Regulation**

***General***

The airline industry is heavily regulated domestically and internationally, especially by the federal government, and there are a significant number of governmental agencies, offices, and legislative bodies that could directly or indirectly affect the Company and the airline industry financially and operationally. Regulations affecting the Company or the airline industry include, but are not limited to, those discussed below. For further discussion of the

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

risks relating to regulation of the Company and the airline industry, see "Risk Factors—Legal, Regulatory, Compliance, and Reputational Risks."

Commercial air carriers in the United States are subject to regulation by the Department of Transportation ("DOT"), which regulates economic operating authority for air carriers and consumer protection for airline passengers, and the FAA, an agency within the DOT which has the authority to regulate safety aspects of civil aviation operations. The FAA manages the nation's labor-intensive air traffic control ("ATC") system. The Company may be subject to civil penalties or cease and desist orders for violations of federal regulations.

The airline industry is dependent on the federal government in terms of its effective management of aviation security and customs functions. The TSA regulates aviation security and operates airport checkpoints and baggage screening systems, while U.S. Customs and Border Protection ("CBP") is responsible for border protection and facilitates the flow of international travel by regulating immigration and customs laws. Other federal entities with influence over airlines include, but are not limited to, the U.S. Department of Justice, which oversees certain airline antitrust matters; the National Mediation Board, which administers the Railway Labor Act governing labor relations in the airline industry; and the Pipeline and Hazardous Materials Safety Administration, which establishes rules for hazardous materials and other dangerous goods transported on aircraft.

The Company is also subject to various state, local, and foreign laws and regulations.

The airline industry may also be impacted by the activities of Congress. For instance, from time-to-time, Congress may be unable to enact appropriations bills to fund one or more of the aforementioned agencies, which may result in a lapse in appropriations and cause a partial government shutdown. Government shutdowns may disrupt important government services, such as ATC functions. A shutdown lasting more than several days, such as the partial government shutdown that occurred from October 1, 2025 through November 12, 2025, has resulted, and may in the future result, in substantial operational and financial burdens on the Company.

**Economic and Consumer Protection Regulation**

***Regulation by the U.S. Department of Transportation***

To provide passenger transportation in the United States, a domestic airline is required to hold a Certificate of Public Convenience and Necessity from the DOT, which is unlimited in duration. The Company's certificate generally permits it to operate among any points within the United States and its territories and possessions. Additional DOT authority, in the form of a certificate or exemption from certificate requirements, is required for a U.S. airline to serve foreign destinations either with its own aircraft or via code-sharing with another airline. Exemptions granted by the DOT to serve international markets are generally limited in duration and are subject to periodic renewal requirements. The DOT may revoke a certificate or exemption, in whole or in part, for failure to comply with federal aviation statutes, regulations, orders, or the terms of the certificate or exemption itself.

The DOT's consumer protection and enforcement authority is derived primarily from a federal statutory prohibition on "unfair or deceptive practices or unfair methods of competition" by air carriers. The DOT also enforces the requirement that air carriers provide safe and adequate air transportation, and the prohibition on discrimination against consumers on the basis of (i) disability and (ii) race, color, religion, national origin, sex, or ancestry.

The DOT has adopted "Passenger Protection Rules," which address a wide variety of matters, including flight delays on the tarmac, chronically delayed flights, denied boarding compensation, baggage liability requirements, ticket refunds, disabled passenger transportation, and advertising of airfares, among others. The Passenger Protection Rules affect the Company's operations and may have a material effect on the Company's capital expenditures and earnings. The DOT's August 2023 rule on accessible lavatories requires airlines to have one accessible (i.e., larger) lavatory on new narrow-body aircraft that are (i) originally ordered after October 3, 2033, (ii) delivered after October 2, 2035, or (iii) part of a new type-certificated design filed with the FAA or a foreign carrier's safety authority after October 2, 2024. The Company anticipates that this rule could impose substantial

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

costs on the Company and have a material effect on the Company's capital expenditures, earnings, and competitive position.

In 2024, the DOT finalized new rules enhancing protections for passengers who use wheelchairs and assistive devices and requiring airlines to provide a full ticket refund to passengers in certain situations involving a cancellation or significant delay. The DOT has also issued a rule related to when and how air carriers must disclose ancillary service fees, although that rule is currently stayed, pending litigation. The DOT may expand upon its rules or issue new rules in the future, which could increase the cost of regulatory compliance.

***Aviation Taxes and Fees***

The federal government requires airlines to collect certain aviation taxes, including an excise tax and a domestic segment tax paid by airline customers, which are used, in part, to finance programs administered by the FAA. Airline passengers are also required to pay a "Passenger Facility Charge" if utilizing a commercial airport with such a user fee, and air carriers pay the federal government a commercial jet fuel tax. Additionally, passengers are subject to federal fees related to the U.S. Department of Homeland Security. Passengers taking trips originating in the United States pay a Transportation Security Fee. International passengers arriving in the United States are subject to U.S. immigration and customs fees which support the CBP and an agriculture inspection fee imposed by the U.S. Department of Agriculture's Animal and Plant Health Inspection Service. Certain of these taxes and fees may be indexed to inflation, and new or higher aviation taxes or user fees on air carriers and/or their customers may be imposed by Congress or the applicable agency at any time.

**Operational and Safety Regulation**

The Company and certain of its third-party service providers are subject to the jurisdiction of the FAA with respect to aircraft maintenance and operations, including equipment, ground facilities, dispatch, communications, training, and other matters affecting air safety. For example, the FAA has rules with respect to crew flight, duty, and rest times. The FAA, from time to time, issues orders or directives relating to the maintenance and operation of aircraft that require significant expenditures or operational restrictions. The FAA also requires airlines to obtain and maintain an Air Carrier Operating Certificate, as well as other certificates, approvals, and authorities. These certificates, approvals, and authorities are subject to amendment, suspension, or revocation for cause. The FAA may issue advisory circulars to provide guidance for compliance with aircraft and pilot certification standards, operational standards, training standards, and other FAA rules.

The FAA Reauthorization Act of 2024 authorizes funding for the FAA through federal fiscal year 2028 and provides direction to various FAA and DOT offices and programs over the next several years, including mandates for new rulemakings. As the airlines' safety regulator, the FAA may utilize a variety of methods, such as temporary flight restrictions, to address safety concerns and control aircraft operations within designated areas. The FAA regulates authorizations to land and take off at certain U.S. airports the Company serves, including Reagan National Airport and LaGuardia Airport. These "slot" restrictions limit operations and regulate capacity. The allocation of slots and additional slot restrictions, exemptions, or waivers, which may be implemented in the future, could affect the Company's operations and strategic initiatives.

The FAA is also the safety regulator of airplane manufacturers and oversees the aircraft certification process. The certification of the -7 is stalled due in part to the FAA's heightened oversight of aircraft manufacturers. The FAA's oversight of the Company's original equipment manufacturers and the rate of production of new planes are outside of the Company's control. The FAA may also require airplane manufacturers to retrofit airplanes to address safety concerns, which could impose substantial costs on the Company. For example, the FAA has finalized a rule requiring commercial aircraft manufactured after August 2025 to have a physical secondary barrier installed between the aircraft's flight deck and cabin to provide additional protection against unauthorized access to the flight deck. The Company is currently installing these modifications on new deliveries of its aircraft. The FAA may also issue regulations requiring installation of secondary barriers on existing commercial aircraft that were manufactured prior to August 2025, which would impose significant costs on the Company.

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

The FAA also manages the nation's ATC system. The U.S. government and the airline industry are increasingly focused on addressing persistent shortages of fully licensed and trained air traffic controllers, as well as modernizing the ATC system through large-scale capital projects. Congress allocated approximately $12.5 billion in 2025 for the FAA to replace outdated technology and infrastructure and recruit and train controllers. Controller shortages and inefficiencies in the ATC system have caused air carrier delays and cancellations, which may significantly impact the Company's operations and cost.

Additionally, the FAA has continued its ongoing effort to implement a multi-faceted, airspace modernization program. The Company has implemented technology and programs intended to comply with applicable requirements, but continued compliance and future equipage mandates could impose substantial costs on the Company. The Company is subject to any operational changes imposed by the FAA as they relate to the modernization program or otherwise.

**Passenger and Occupational Health Regulation** 

The Company is subject to various other federal, state, and local laws and regulations relating to health and occupational safety, including Department of Health and Human Services, Centers for Disease Control and Prevention, Occupational Safety and Health Administration, and Food and Drug Administration regulations. New health requirements or standards, whether mandated by government agencies or voluntarily adopted by the Company, could affect the Company's costs and performance.

**Security Regulation**

The TSA and the CBP are responsible for certain civil aviation security matters affecting U.S. air carriers. TSA regulations and procedures address, among other things, (i) flight deck security; (ii) the use of federal air marshals onboard flights; (iii) airport and aircraft access security; (iv) airline crew security training; (v) security screening of passengers, baggage, cargo, mail, employees, and vendors; (vi) training and qualifications of security screening personnel; (vii) provision of passenger data to CBP; (viii) background checks; and (ix) certain cybersecurity requirements. The CBP is the federal agency charged with facilitating international trade, collecting import duties, and enforcing U.S. regulations with respect to trade, customs, and immigration.

TSA or CBP personnel and mandated security procedures can affect the Company's operations, costs, and Customer Experience. For example, as part of its security measures, the TSA requires airlines to collect passengers' personal information to identify individuals for more extensive security screening, which has raised privacy concerns by some air travelers. TSA and CBP procedures and lack of sufficient numbers of personnel have also caused delays at screening checkpoints. The TSA has expressed its plans to leverage advanced transportation security screening technologies, including biometric solutions, to improve security effectiveness and operational efficiency. The advanced technologies have prompted privacy, cost, and legal concerns from air carriers, travelers, and advocacy groups.

The Company works collaboratively with the TSA, CBP, foreign governments, and airports to provide risk-based security measures at international locations served by the Company. The Company has also made significant investments in facilities, equipment, and technology to inspect and process Customers, checked baggage, and cargo efficiently in compliance with applicable security regulations. However, the Company is not able to predict the impact, if any, that any new security measures or TSA or CBP resource limitations at certain airports will have on Passenger revenues and the Company's costs, either in the short-term or the long-term.

**Environmental Regulation**

The Company is subject to various federal laws and regulations relating to the protection of the environment, including the Clean Air Act, the Resource Conservation and Recovery Act, the Clean Water Act, the Safe Drinking Water Act, and the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), as

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

well as state and local laws and regulations. These laws and regulations govern aircraft drinking water, emissions, storm water discharges from operations, and the disposal of materials such as jet fuel, chemicals, hazardous waste, and aircraft deicing fluid.

In conjunction with airport authorities, other airlines, and state and local environmental regulatory agencies, the Company, as a normal course of business, undertakes voluntary investigation or remediation of soil or groundwater contamination at various airport sites. The Company has not historically experienced any airport site environmental liability that has had a material adverse effect on its capital expenditures, earnings, or competitive position. However, many airports, as well as federal, state, and local governmental authorities, are increasingly focused on groundwater contamination caused by per- and polyfluoroalkyl substances ("PFAS"). PFAS are a key component in foam used to fight petroleum-based fires at both commercial and military aviation facilities. Regulatory authorities at the federal, state, and local levels are moving forward with prohibitions on the manufacturing, use, or sale of PFAS-based foam, as well as costly remediation efforts at airports to address groundwater contamination. In April 2024, the U.S. Environmental Protection Agency (the "EPA") issued a final rule listing two specific types of PFAS as hazardous substances under CERCLA and requiring entities to report releases that meet or exceed a reportable quantity to the EPA and applicable state and local agencies. The evolving legal and regulatory activity surrounding PFAS could lead to an inadequate supply of FAA-certified firefighting foam throughout the aviation system, additional costs associated with transitioning away from products containing PFAS, potential environmental incident prevention or cleanup costs for historic use of hazardous substances, and/or increased operating costs at certain airports. Moreover, listing PFAS compounds under CERCLA may give rise to strict, joint and several liability for removal, remedial, response, and other costs, the costs of which could be material.

Members of the United Nations' International Civil Aviation Organization ("ICAO") have agreed to a series of measures to reduce GHG emissions within the aviation sector. At the federal level, the EPA adopted aircraft GHG emissions standards in December 2020, which apply to airframe and aircraft engine manufacturers and align with the standards previously adopted by ICAO. The FAA finalized these standards in February 2024, mandating improved fuel efficiency certification regulations for airplanes manufactured after January 1, 2028. The Company has not and does not expect to incur any material costs related to the EPA's aircraft GHG emissions rules at this time, and the rules are not expected to adversely impact the Company's current aircraft fleet; however, the Company cannot guarantee that more stringent standards will not be adopted by Congress, the FAA, or the EPA in the future that could require material capital expenditures to modernize or replace its aircraft fleet or incur other costs related to GHG emissions from its aircraft. The Company may also face new regulation of aircraft emissions in the U.S. or internationally, potentially subjecting the Company to further taxes, environmental fees, or requirements to obtain permits or offsets for GHG emissions in certain jurisdictions.

In addition to aircraft emissions standards, ICAO has adopted its Carbon Offsetting and Reduction Scheme for International Aviation ("CORSIA") program, a global market-based measure intended to cap carbon emissions from international civil aviation at their 2019 levels from 2021 to 2023 and 85 percent of their 2019 levels from 2024 to 2035. CORSIA calls for international aviation emissions above these levels to be offset or reduced through the use of carbon offsets or eligible sustainable fuels. The U.S. has not enacted legislation to implement CORSIA. However, the Company is voluntarily monitoring its international emissions for reporting purposes and to determine carbon offsetting requirements under the CORSIA program. The future costs of adhering to CORSIA are uncertain, and the Company could face increased costs to purchase additional volumes of SAF or carbon offsets, or to take other measures to adhere to the CORSIA program or other similar climate-change related mandates in the future. To date, the Company has not incurred any material costs related to CORSIA; however, the Company could experience material costs as a result of future changes to the CORSIA program or the expansion of its international operations, which could increase its potential obligations under CORSIA.

The federal government and several U.S. states have also enacted or proposed climate-related disclosure laws that would require the Company to evaluate and report climate-related risks. For example, the State of California requires reporting related to voluntary carbon offsets, and the Securities and Exchange Commission has considered new rules requiring disclosure of certain climate-related information. California has also enacted climate-disclosure laws which are subject to legal challenge and would require the Company to disclose GHG emissions and a climate-

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

related financial risk report. The timing and scope of future legislation, if passed into law, is uncertain at this time. The reporting obligations of state or federal laws or rules requiring the disclosure of climate-related risks may cause the Company to incur increased costs with respect to modifying existing disclosure controls, financial reporting practices, and the gathering and reporting of emissions data. For further discussion of the risks relating to these reporting obligations, see "Risk Factors—Legal, Regulatory, Compliance, and Reputational Risks."

In addition to climate change, aircraft noise continues to be an environmental focus. The Airport Noise and Capacity Act of 1990 gives airport operators the right, under certain circumstances, to implement local noise abatement programs. Some airports have established airport restrictions to limit noise, including restrictions on aircraft types to be used and limits on the number of hourly or daily operations or the time of operations. Foreign governments may enact or allow airports to enact similar restrictions. These types of restrictions can cause curtailments in service or increases in operating costs, limit the ability of air carriers to expand operations at the affected airports, block access for new entrants, impede the implementation or use of more efficient flight paths, and result in civil fines when operators violate curfews or noise limitations.

Government efforts at the international, federal, state, or local levels to address worldwide climate change, manage GHG emissions, and reduce aircraft noise, to the extent pursued or implemented, could affect the Company, aircraft operators, original equipment manufacturers, producers and sellers of aviation fuel, and other third parties on which the Company is dependent. Additional legislative or regulatory activity in this area could require modifications to the Company's equipment, operations, and strategy, and could have a material effect on the Company's capital expenditures, earnings, or competitive position. The Company does not currently expect any such effects to be material. However, until the timing, scope, and extent of such future developments become known, the Company cannot accurately predict their effect on the Company's cost structure or its operating results.

**Data Privacy and Cybersecurity Regulation**

The Company is subject to increasingly complex legislative, regulatory, and customer expectations related to data privacy, AI, and cybersecurity risk management across a variety of domestic and international jurisdictions. Existing and evolving requirements could result in risks or challenges such as expanded compliance burdens, operational changes, and enforcement risks for the Company. For further discussion of the risks relating to data privacy and cybersecurity, see "Risk Factors—Information Technology, Cybersecurity, and Data Privacy Risks."

Regulators and certain jurisdictions, including the European Union, the U.K., and numerous states within the United States, have passed laws relating to the notice, collection, processing, use, retention, protection, and transfer of personal information as well as the protection of sensitive information and critical systems. In some cases, such laws and regulations can be enforced by private parties in addition to regulators. The Company processes, stores, and transmits sensitive data that includes information such as Customer and Employee data, credit card numbers, sensitive security information, and other regulated information for a variety of business purposes. The Company, therefore, is subject to various risks and costs associated with such activities, including costs associated with compliance with U.S. and foreign data collection and privacy laws and various contractual obligations.

The Company must also comply with evolving payment card association and network operating rules, including data security rules, certification requirements, and rules governing electronic fund transfers. For example, the Company must comply with evolving Payment Card Industry Data Security Standards ("PCI DSS"), which impose stringent requirements on how the Company processes and protects payment card data. Failure to maintain PCI DSS compliance or the compromise of cardholder data that the Company processes, stores, or transmits could result in costs, fees, fines, penalties, and restrictions on the Company's ability to process payment card transactions, which could materially impact operations and Customer Experience.

As the Company expands into new locations, enters international partnerships, and participates in other global activities, it may be required to comply with foreign laws like the EU's General Data Protection Regulation, which could impose additional data privacy and cybersecurity requirements upon the Company along with significant compliance obligations and substantial penalties for non-compliance.

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

The Company is subject to broadly applicable cybersecurity legal obligations and has experienced heightened legislative and regulatory focus on cybersecurity due to its designation as critical infrastructure and its federal contractor status. The Company must comply with a developing set of cybersecurity requirements, including, but not limited to, reporting obligations, technical security measures, internal and external coordination, cyber-related risk-management and governance obligations, and other compliance requirements related to information technology systems and operational technology systems. In 2025, the Company completed a series of distinct cybersecurity inspections conducted by the TSA, FAA, and Department of Defense, each designed to assess compliance with their respective regulatory requirements. Failure to comply with emerging cybersecurity obligations or to address identified gaps could lead to enforcement actions, monetary penalties, operational limitations, or reputational damage.

Additionally, there are emerging regulations and state laws around AI, including those in California and Colorado, that may soon require companies that develop or deploy AI systems to establish formal governance structures and internal controls, including designated oversight personnel, documented risk assessment procedures, and regular compliance reviews of their AI systems. The Company has established an internal AI governance team, and the Company's Board of Directors oversees AI risks through its Audit Committee and at the full Board level. AI usage and governance continues to evolve, and the Company may become subject to regulations that effect its operations and increase its costs.

**International Regulation**

All international air service is subject to certain U.S. federal requirements and approvals, as well as the regulatory requirements of the appropriate authorities of the foreign countries involved. Foreign regulatory agencies located in jurisdictions served by the Company can impose requirements on various aspects of the Company's business, including safety, marketing, ticket sales, staffing, and tax. Foreign countries may also enact passenger protection rules similar to or exceeding the DOT's rules, which could impose additional costs and liabilities on the Company.

The Company has obtained the necessary economic authority from the DOT, as well as approvals required by the FAA and applicable foreign government entities, to conduct operations, under certain circumstances, to points outside of the continental United States currently served by the Company. Certain international authorities and approvals held by the Company are subject to periodic renewal requirements. To the extent the Company seeks to serve additional foreign destinations in the future, or to renew its authority to serve certain routes, it may be required to obtain necessary authority from the DOT and/or approvals from the FAA, as well as any applicable foreign government entity. To the extent the Company expands its international flight offerings, CBP and its requirements and resources will also become increasingly important considerations to the Company.

Certain international markets are governed by bilateral air transportation agreements between the United States and foreign countries, which may be subject to renegotiation or reinterpretation from time to time. Changes in U.S. or foreign government aviation policies could result in the alteration or termination of such agreements, diminish the value of the Company's existing international authorities, present barriers to renewing existing or securing new authorities, or otherwise affect the Company's international operations. There are also capacity limitations at certain international airports, which could impact future service levels. While the U.S. government has negotiated "open skies" agreements with many countries, which allow for reciprocal unrestricted access between the United States and respective foreign destinations, airport gate and/or limitations on commercially viable slot times may impede the Company's service or growth. Further, agreements with other non-open skies countries may restrict or limit the Company's entry into those destinations and/or its related growth opportunities.

**Insurance**

The Company carries insurance of types customary in the airline industry and in amounts the Company deems adequate to protect the Company and its property and to comply both with applicable regulations and certain of the Company's credit and lease agreements. The policies principally provide coverage for public and passenger liability,

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

property damage, pollution, D&O/fiduciary, cargo and baggage liability, loss or damage to aircraft, engines, and spare parts, and workers' compensation. In addition, the Company carries a cybersecurity insurance policy with regards to data protection and business interruption associated with both security breaches from malicious parties and from certain system failures. The Company also manages insured risk through the use of reinsurance programs, pooling mechanisms, and a wholly-owned captive insurance subsidiary. For a discussion of the risks related to the Company's insurance coverage, see "Risk Factors."

**Industry and Competition**

Historically, the airline industry has been an extremely volatile industry. Among other things, it has been cyclical, energy intensive, labor intensive, capital intensive, technology intensive, highly regulated, heavily taxed, and extremely competitive. The airline industry has also been particularly susceptible to detrimental events such as U.S. government shutdowns, economic recessions, jet fuel price volatility, unscheduled maintenance disruptions, outbreaks of disease and/or pandemics, supply chain challenges, acts of terrorism or war, geopolitical unrest, severe weather, and natural disasters. In 2025, the U.S. airline industry continued to face challenges such as the historically prolonged government shutdown (which impacted key functions such as TSA and the ATC system and mandated industry capacity reductions), inflationary cost pressures (particularly labor costs), delayed aircraft deliveries, shifting travel demand patterns, economic uncertainty, disruptive weather events, and natural disasters. In response to ever-evolving travel patterns, the Company and several other U.S. airlines implemented route network changes and evaluated capacity.

Competition within the airline industry is intense and highly unpredictable, and Southwest has historically competed with other airlines on virtually all of its scheduled routes. In recent years, the majority of domestic airline service has been provided by Southwest and the other largest major U.S. airlines, including American Airlines, Delta Air Lines, and United Airlines. The DOT defines major U.S. airlines as those airlines with annual revenues of at least $1 billion; there are currently 14 passenger airlines offering scheduled service, including Southwest, that meet this standard.

Key competitive factors within the airline industry include (i) pricing and cost structure; (ii) routes, loyalty programs, and schedules; (iii) customer service, operational reliability, product offerings, and amenities; and (iv) balance sheet health. Airlines, including Southwest, also compete for customers with alternatives to air travel, such as driving, videoconferencing, and business communication platforms. These communication alternatives have become particularly prevalent post-pandemic.

**Pricing and Cost Structure**

Pricing is a significant competitive factor in the airline industry, and the availability of fare information on the Internet allows travelers to easily compare fares and identify competitor promotions and discounts. During 2025, the Company continued to experience a highly competitive fare environment.

Pricing can be driven by a variety of factors. For example, airlines may discount fares to stimulate traffic in new markets, increase traffic in existing markets, and/or grow market share in existing markets. Some airlines have been able to offer more competitive fares through measures designed to lower operating costs. Common efforts include fleet transformation to gain fuel efficiencies, fleet simplification, and increasing the number of seats per trip through seat retrofits and the use of larger aircraft.

The Company believes its cost structure has historically provided it with an advantage over many of its airline competitors by enabling it to charge competitive fares, and the Company remains focused on driving efficiencies to offset overall inflationary cost pressures.

**Routes, Loyalty Programs, and Schedules**

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

The Company also competes with other airlines based on markets served, loyalty opportunities, and flight schedules. While the Company has a robust route network in the United States, some major airlines have more extensive global route structures than Southwest, including more extensive international networks. In addition, many competitors have entered into significant commercial relationships with other airlines, such as strategic alliances, code-sharing, and capacity purchase agreements, which increase the airlines' opportunities to expand their route offerings. Depending on the nature of the specific alliance, code-sharing arrangement, or capacity purchase agreement, a participating airline may be able to, among other things, (i) offer its customers access to more destinations than it would be able to serve on its own, (ii) gain exposure in markets it does not otherwise serve, and (iii) increase the perceived frequency of its flights on certain routes. More extensive route structures, as well as alliance and code-sharing arrangements, not only provide additional route flexibility for participating airlines, but they can also allow these airlines to offer their customers more opportunities to earn and redeem loyalty miles or points. In 2025 and first quarter 2026, the Company launched such partnerships with Icelandair, Hahnair, China Airlines, EVA Air, Philippine Airlines, Condor, and Turkish Airlines to provide transoceanic connectivity. The Company is exploring additional gateways with these existing partners, as well as additional partnerships with other airlines, in 2026 in an effort to enhance its route offerings.

**Customer Service, Operational Reliability, Product Offerings, and Amenities**

Southwest also competes with other airlines with respect to customer service, operational reliability (such as ontime performance), product offerings, and passenger amenities. Southwest competes with airlines that have more seating options and associated passenger amenities, including first class, business class, and other related amenities, which can appeal in particular to business customers. The Company believes the introduction of assigned and extra legroom seating provides an opportunity to increase the Company's market share of business customers. As part of its product offerings evolution, in 2025, the Company also introduced a new, Basic fare product to appeal to Customers who prioritize lower fare price.

New and different types of aircraft flown by competitors could have operational attributes and passenger amenities that could be considered more attractive to certain consumers than those associated with the Company's existing fleet. Some of the Company's competitors have added, and may continue to add, passenger amenities not offered by the Company, including through new aircraft types and configurations. While Southwest historically utilized an open seating model, the Company began to assign seats, offer extra legroom seating options, and evolve its boarding processes in January 2026. The Company also introduced a refreshed cabin design, and has received initial deliveries of aircraft with new, more comfortable RECARO seats. The Company has further expanded its competitive product offerings with redeye flights, airline partnerships aimed at delivering international connectivity, and an in-house vacation package through Getaways. These initiatives are designed to elevate the Customer Experience and enable the Company to better compete with other airlines' product offerings and passenger amenities.

Carriers are also increasingly focusing on customer-friendly policies as opportunities to win and retain customers. The Company continuously reviews the effectiveness of its Customer policies in achieving its commercial objectives. The Company believes its Customer Service and policies (including those listed below) continue to positively differentiate it from many of its competitors.

&nbsp;&nbsp;&nbsp;&nbsp;• The Company offers free in-flight Wi-Fi for all Rapid Rewards Members through a partnership with T-Mobile;

&nbsp;&nbsp;&nbsp;&nbsp;• The Company offers competitive fares and does not charge change fees for most fare products (although fare differences may apply) or cancellation fees (subject to the Company's No Show policy);

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

The Company has maintained its investment-grade rating by all three major credit agencies (Moody's, S&P Global, and Fitch), and is one of only two major U.S. passenger airlines with an investment-grade rating by all three major credit agencies. The Company believes its strong balance sheet and focus on prudent capital deployment will support its strategic plans and initiatives. The Company's capital allocation framework supports its continued commitment to a strong and efficient investment-grade balance sheet. The Company intends to preserve the strength of its balance sheet through manageable debt maturities and a targeted liquidity balance, comprised of cash and cash equivalents, short-term investments, and a revolving credit line, with the goal of maintaining a targeted leverage ratio of adjusted debt to adjusted earnings before interest, taxes, depreciation, amortization, and rent. The Company also intends to continue returning value back to its Shareholders through dividends and opportunistic share repurchases. The Company plans to continually review its return of capital program, taking into account the Company's free cash flow, leverage, and fleet monetization strategy.

**Other Forms of Competition**

Technology advancements have provided alternatives to air travel, such as videoconferencing, business communication platforms, and the Internet, and these alternatives have significantly increased in scope in recent years. There is risk that the significantly increased use of these alternatives could result in permanent changes to consumer behavior and thereby negatively affect demand for air travel.

The airline industry is also subject to varying degrees of competition from other forms of transportation, including public charter operators and surface transportation by automobiles, buses, and trains. Inconveniences and delays associated with air travel security measures can increase surface competition. In addition, surface competition can be significant during economic downturns when consumers cut back on discretionary spending and fewer choose to fly, or when gasoline prices are lower, making surface transportation a less expensive option. The Company has historically provided a relatively high percentage of short-haul travel, and thus has been particularly exposed to competition from surface transportation in these instances.

**Seasonality**

The Company's business is ordinarily seasonal. In most markets the Company serves, demand for air travel has historically been greater, and, therefore, revenues in the airline industry tend to be stronger, during the summer months and peak travel periods, including holidays. As a result, in many cases, the Company's results of operations reflect this seasonality. Factors that could alter this seasonality include, among others, the price of fuel, general economic conditions, changes in consumer behavior, governmental action, including shutdowns, global pandemics, extreme or severe weather and natural disasters, fears of terrorism or war, or changes in the competitive environment. Therefore, the Company's quarterly operating results are not necessarily indicative of operating results for the entire year, and historical operating results in a quarterly or annual period are not necessarily indicative of future operating results.

**Human Capital Resources**

***Employees***

As of December 31, 2025, the Company had 72,790 active full-time equivalent Employees, consisting of 32,214 air operations (including Pilots, Flight Attendants, Dispatchers, Flight Simulator Technicians, Flight Crew Training Instructors, and Meteorologists), 21,734 ground operations (including Ramp, Operations, Provisioning, Freight Agents, and Customer Service Agents), 2,629 Customer Representatives and Source of Support Representatives, 3,727 maintenance and engineering (including Material Specialists, Mechanics, Aircraft Appearance Technicians, and Facilities Maintenance Technicians), and 12,486 additional "noncontract" Employees. The Company has consistently utilized active full-time equivalent Employees to determine various metrics that measure productivity and efficiency, so it has chosen to not include on-leave Employees in the figure, which totaled an additional 4,607 Employees as of December 31, 2025. In addition, the active full-time equivalent Employees figure includes an adjustment to count all part-time Employees as a 0.5 full-time equivalent Employee. When considering total

demographics of Employees, however, the Company looks at total headcount, active and on-leave Employees, irrespective of part-time or full-time status.

In February 2025, the Company implemented a reduction in workforce, which reduced approximately 1,750 Employee roles, or approximately 15 percent of corporate positions. As of December 31, 2025, the Company's number of active full-time equivalent Employees increased by 0.5 percent, year-over-year, due in part to the hiring of full-time equivalent contract Employees. The Company plans to continue efforts to right-size staffing, with the goal of running a safe, reliable, and efficient operation.

***Global Innovation Center***

In November 2025, the Company formed Southwest Airlines India Private Limited, a wholly-owned subsidiary, in Hyderabad, India. The subsidiary is a Global Innovation Center intended to enhance Southwest's delivery model by transitioning the delivery of certain critical business functions from the Company's international vendor network to internal Employees and decreasing the Company's reliance on existing resources.

***Labor Union Activity***

Approximately 84 percent of Company Employees as of December 31, 2025, were represented by labor unions. The Railway Labor Act establishes the right of airline employees to organize and bargain collectively. Under the Railway Labor Act, collective-bargaining agreements between an airline and a labor union generally do not expire, but instead become amendable as of an agreed date. By the amendable date, if either party wishes to modify the terms of the agreement, it must notify the other party in the manner required by the Railway Labor Act and/or described in the agreement. After receipt of the notice, the parties must meet for direct negotiations. If no agreement is reached, either party may request the National Mediation Board to appoint a federal mediator. If no agreement is reached in mediation, the National Mediation Board may determine an impasse exists and offer binding arbitration to the parties. If either party rejects binding arbitration, a 30-day "cooling off" period begins. At the end of this 30-day period, the parties may engage in "self-help," unless a Presidential Emergency Board is established to investigate and report on the dispute. The appointment of a Presidential Emergency Board maintains the "status quo" for an additional period of time. If the parties do not reach agreement during this period, the parties may then engage in "self-help." "Self-help" includes, among other things, a strike by the union or the airline's imposition of any or all of its proposed amendments and the hiring of new employees to replace any striking workers. Since October 2022, each of the 12 union-represented workgroups have ratified new contracts.

The following table sets forth the Company's Employee groups subject to collective bargaining and the status of their respective collective-bargaining agreements as of December 31, 2025:

**<u>Financial Risks</u>**

***The airline industry is particularly sensitive to changes in economic conditions; in the event of continued or future unfavorable economic conditions or economic uncertainty, the Company's results of operations could be further negatively affected, which could require the Company to further adjust its business strategies.***

The airline industry, which is subject to relatively high fixed costs and highly variable and unpredictable demand, is particularly sensitive to changes in economic conditions, including changes in consumer discretionary spending as a result of inflation, rising interest rates, or other factors. Historically, unfavorable U.S. economic conditions have driven changes in travel patterns and have resulted in reduced spending for both leisure and business travel. For some consumers, leisure travel is a discretionary expense, and short-haul travelers, in particular, have the option to replace air travel with surface travel.

Businesses and other travelers are able to forego air travel by using other communications such as videoconferencing, business communication platforms, and the Internet. Further, some businesses allow their employees to work remotely and/or restrict non-essential travel for their employees, which has impacted the demand for business air travel. In addition, to the extent business travel demand increases, businesses may require the purchase of less expensive tickets to reduce costs. This, in turn, can result in a decrease in average revenue per seat.

During unfavorable economic conditions, low fares are often used to stimulate traffic. However, offering low fares typically hampers the ability of airlines to counteract any increases in fuel, labor, and other costs. Consumer behavior related to traveling may be negatively impacted by adverse changes in the perceived or actual economic climate, including declines in income levels or disposable income, and/or loss of wealth resulting from the impact of economic conditions. Government foreign-relations actions, including tariffs and immigration policies, may also reduce the willingness of non-U.S. persons to travel to or within the United States, including by air. Any continuing or future U.S. or global economic uncertainty could further negatively affect the Company's results of operations and could cause the Company to further adjust its business strategies. Additionally, because a significant portion of expenses to operate a flight do not vary significantly with the number of passengers carried, a relatively small change in the number of passengers can have a disproportionate effect on an airline's operating and financial results. Therefore, any general reduction in airline passenger traffic could adversely affect the Company's results of operations.

***The Company's business can be significantly affected by the availability of jet fuel, fuel prices, and volatility of fuel prices and the Company's operations are subject to disruption in the event of any delayed supply of fuel; therefore, the Company's strategic plans and future profitability are likely to be affected by fuel availability, price increases, and fuel price volatility.***

Airlines are inherently dependent upon energy to operate, and jet fuel and oil represented approximately 19 percent of the Company's operating expenses for 2025. Even a small change in market fuel prices can significantly affect

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

profitability. The cost of fuel can be extremely volatile and unpredictable and is subject to many external factors and market expectations that are beyond the Company's control. For example, fuel prices can be impacted by geopolitical, environmental (including those related to climate change), and economic factors, such as (i) dependency on foreign imports of crude oil and potential or actual hostilities or other conflicts in oil producing areas or along global trade routes; (ii) limitations and/or disruptions in domestic refining or pipeline operations or capacity due to weather, natural disasters, or other factors; (iii) worldwide demand for fuel, particularly in developing countries, which can result in inflated energy prices; (iv) changes in U.S. governmental policies on fuel production, transportation, taxes, and marketing; (v) imposition of economic sanctions on oil-producing countries or specific industry participants; and (vi) changes in currency exchange rates.

The Company is also reliant upon the readily available supply and timely delivery of jet fuel to the airports that it serves. A disruption in refinery production or related service and transportation operations affecting supply could present significant challenges to the Company's operations and could ultimately cause the cancellation of flights and/or hinder the Company's ability to provide service to a particular airport. In addition, the occurrence of extreme weather events (regardless of cause), such as flooding, acute or prolonged winter storms, tropical storms, and hurricanes, can also disrupt the jet fuel supply chain and affect fuel prices.

The Company's ability to mitigate the impact of fuel price increases or volatility through increased fares or fees could also be limited by the competitive nature of the airline industry and the unpredictability of the market for air travel. Passengers often purchase tickets well in advance of their travel, and the Company may not be able to increase fares, impose fuel surcharges, increase revenues, or decrease other operating costs sufficiently to offset rapid or prolonged fuel price increases. Further, the Company faces the risk that higher fares may drive a decrease in air travel demand generally or a disproportionate decrease in leisure travel due to price sensitivity. Conversely, prolonged periods of low fuel prices may hinder the Company's ability to execute on its strategic initiatives as other carriers compete by offering lower fares, flying longer-haul routes, or increasing capacity.

Historically, the Company attempted to manage its risk associated with volatile jet fuel prices by utilizing over-the-counter fuel derivative instruments to hedge a portion of its future jet fuel purchases. However, based on higher fuel hedging premium costs over time and other factors, the Company terminated its remaining fuel hedge positions in second quarter 2025 and does not intend to add new fuel derivatives to its portfolio. The Company may review its approach to hedging from time to time based on market conditions and other factors. Purchasing jet fuel at prevailing market prices, which could change substantially over short periods of time, may make the Company's earnings more vulnerable to volatile fuel prices and could have a material adverse effect on the Company's results of operations and financial condition. If the Company were to resume its fuel hedging program in the future, it cannot guarantee that the fuel derivatives it uses will provide adequate protection against significant increases in fuel prices. In certain cases, the type of derivative instruments utilized could result in hedging losses, which could result in the Company effectively paying higher than market prices for fuel, thus creating additional volatility in the Company's earnings. The Company's ability to enter into fuel derivative instruments in the future could also be limited by market conditions.

The Company's prior period fuel hedging arrangements and the various potential impacts of hedge accounting on the Company's financial position, cash flows, and results of operations are discussed in more detail under "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Quantitative and Qualitative Disclosures About Market Risk," and in Note 1 and Note 10 to the Consolidated Financial Statements.

***The Company's low-cost structure has historically been one of its primary competitive advantages, and many factors have adversely affected and could continue to adversely affect the Company's ability to control its costs.***

The Company's low-cost structure has been one of its primary competitive advantages, as it has generally enabled the Company to offer low fares, drive traffic volume, grow market share, and protect profits. As discussed below under "Management's Discussion and Analysis of Financial Condition and Results of Operations," the Company has experienced significant inflationary cost pressure, particularly with respect to Salaries, wages, and benefits

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

expense. The Company's low-cost structure can also be negatively impacted by costs over which the Company has limited control. These include costs such as fuel, labor (especially union labor), airport, and regulatory compliance costs.

The Company's ability to control labor costs is limited by the terms of its collective-bargaining agreements. These agreements include required work rules and wage-rate provisions, as well as other negotiated terms, that may restrict the Company's operational flexibility and result in increased staffing or scheduling inefficiencies, thereby pressuring its cost structure relative to certain competitors. The Company's unionized workforce makes up approximately 84 percent of its Employees and many have had pay scale increases as a result of contractual rate increases, which has increased the Company's labor costs. Further, in response to staffing challenges, the Company has increased the minimum pay for certain of its workforce and provided incentive pay in certain instances. If new or amended labor agreements include additional pay increases, work rule requirements, or other terms that further elevate costs, the Company's competitive cost position could be adversely affected.

As discussed under "Business - Regulation," the airline industry is heavily regulated, and the Company's regulatory compliance costs are subject to potentially significant increases from time to time based on actions by regulatory agencies that are out of the Company's control. Additionally, because of airport infrastructure updates and other factors, the Company has experienced increased space rental rates at various airports in its network. Further, the Company cannot control decisions by other airlines to reduce their capacity. When this occurs, as it has at times during recent years, certain fixed airport costs are allocated among a fewer number of total flights, which can result in increased landing fees and other costs for the Company.

The Company is reliant upon third-party vendors and service providers, and the Company's competitive position is dependent in part on its ability to obtain and maintain commercially reasonable terms with those parties. Disruptions to capital markets, shortages of skilled personnel, supply chain disruptions, increased regulation, geopolitical developments, tariffs, and/or adverse economic conditions could subject certain of the Company's third-party vendors and service providers to significant financial pressures, which could lead to delays and other performance issues, ceased operations, or even bankruptcies among these third-party vendors and service providers. If a third-party vendor or service provider is unable to fulfill its commitments to the Company, the Company may be unable to replace that third-party vendor or service provider in a short period of time, or at competitive terms, which could have a material adverse effect on the Company's results of operations.

The Company participates in fuel consortium arrangements and fuel committees at certain airports. Fuel consortiums and fuel committees have, directly or indirectly, incurred debt obligations for improvements and capital projects for fuel facilities. While each participating airline in a consortium is generally allocated a share of the consortium's costs based on usage, the inability of other participating airlines to satisfy their obligations with respect to fuel consortiums and fuel committees could adversely impact the Company's financial results.

 ***Increases in insurance costs or reductions in insurance coverage may adversely impact the Company's operations and financial results.***

As discussed under "Business - Insurance," the Company carries insurance of types customary in the airline industry. Although the Company has been able to purchase aviation, property, liability, pollution, cybersecurity, and D&O/fiduciary insurance via the commercial insurance marketplace, costs have generally increased, and it is more difficult and, in some cases not possible, to obtain insurance for certain activities and weather-related events. For instance, the cost of insurance premiums related to hail and wind damage has increased for certain facilities, and certain flood insurance is no longer available. Available commercial insurance could be more expensive in the future and/or have material differences in coverage than insurance that has historically been provided and may not be adequate to protect against the Company's risk of loss from future events, including acts of terrorism and severe weather events. With respect to any insurance claims, policy coverages and claims are subject to acceptance by the many insurers involved and may require arbitration, mediation, and/or litigation to effectively settle the claims over prolonged periods of time. The Company's wholly-owned insurance captive uses actuarial services to determine the value of policies and reserves, which can be subject to fluctuation as past trends are not always indicative of future

loss developments. In addition, an aircraft accident or other incident involving Southwest could result in costs in excess of its related insurance coverage, which costs could be substantial. Any aircraft accident or other incident involving Southwest or Southwest's strategic partners, even if fully insured, could also have a material adverse effect on the public's perception of the Company, which could harm its reputation and business.

***The Company's business, operating results, and financial condition could be adversely impacted if it is unable to effectively execute its strategic plans.***

The Company is reliant on the success of its strategic plans and initiatives to increase revenues and help offset increasing costs. The execution of the Company's strategic plans have been and may again be negatively affected by macroeconomic conditions. In both 2024 and 2025, the Company announced plans for, and is in the process of implementing, certain transformational initiatives, such as changing to an assigned seating model, offering extra legroom seating, formalizing partnerships with international carriers to expand its network, offering Getaways by Southwest, introducing 24-hour operations, reducing the turn times between flights, and introducing bag fees for most fare products. The Company's transformational initiatives are discussed in more detail under "Business." The Company made certain assumptions in developing its strategic plans and initiatives related to, for example, customer demand (in light of changing economic conditions), fuel costs, delivery of aircraft, aircraft certification approval timelines, labor market constraints and related costs, supply chain constraints, inflationary pressures, voluntary or mandatory groundings of aircraft, its network, competition, market consolidation, and other macroeconomic and geopolitical factors. The timely and effective execution of the Company's strategies is dependent upon, among other factors, (i) the Company's ability to balance its network schedule and capacity with the availability and location of its crew resources; (ii) the Company's ability to effectively balance its investment of incremental operating expenses and capital expenditures related to its strategies against the need to effectively control costs; (iii) the Company's ability to timely and effectively implement, transition, and maintain related information technology systems and infrastructure; (iv) the Company's ability to secure labor agreements or modifications necessary to support certain operational or strategic initiatives; (v) the Company's ability to maintain satisfactory relations with its Employees or its Employees' representatives; (vi) the Company's ability to retain and broaden its Customer base; and (vii) the Company's dependence on third parties with respect to the execution of its strategic plans. The Company's commercial and operational initiatives are designed to meet evolving Customer preferences, increase revenue opportunities, mitigate cost pressures, and modernize processes. Nevertheless, these measures and any future initiatives may hurt the Company's competitive position and Customer loyalty rather than improve it and may not be successful in increasing revenues or offsetting costs. Furthermore, the execution of the Company's strategic plans may exacerbate other risks described in this Form 10-K. Actual conditions may be different from the Company's assumptions at any time and could cause the Company to further adjust its strategic plan. Additionally, the implementation of these initiatives may create logistical or reputational challenges that could harm the operational performance of the airline or result in decreased demand for air travel on Southwest. If the Company does not successfully execute its transformational initiatives or other strategic plans, or if actual results vary significantly from its expectations, the Company's business, operating results, and financial condition may be adversely affected.

***The airline industry is intensely competitive.***

As discussed in more detail under "Business—Competition," the airline industry is intensely competitive. The Company's primary competitors include other major domestic airlines, as well as regional and new entrant airlines, public charter operators, surface transportation, and alternatives to transportation such as videoconferencing, business communication platforms, and the Internet.

The Company's historical low-fare position has been challenged by the removal of fare floors for certain routes by other carriers, leading to a lower fare offering across the industry, as well as "unbundled" service offerings by some carriers, which appeal to price-sensitive travelers through promotion to consumers of relatively low base fare options. Additionally, most major U.S. airlines offer expanded cabin segmentation fare products, such as "basic economy," "premium economy," and "first class" products. To meet Customer preferences and better compete with the major U.S. airlines, the Company has moved to a more segmented approach, offering a basic economy product

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

and a premium economy fare product with extra legroom. The Company has also moved to an assigned seating model and now charges bag fees for most fare products. The competitiveness of the Company's offerings could be adversely affected if it is unable to implement new initiatives in a timely and successful manner or if Customers are unwilling to accept the Company's product and policy changes. If the Company cannot adequately retain and attract Customers or differentiate its product offerings from those of its competitors, then its business, financial condition, and results of operations could be materially adversely affected.

The Company's revenues are sensitive to the actions of other carriers with respect to pricing, routes, loyalty programs, scheduling, capacity, customer service, operational reliability, comfort and amenities, product offerings, cost structure, aircraft fleet, strategic alliances, and code-sharing and similar activities. Many of the Company's competitors participate in joint ventures and international alliances, providing for increased financial resources and improved profit margins. Many major U.S. airlines also offer longer-haul, international routes through extensive global networks. In order to compete with these activities and expand its transatlantic and transpacific service offerings, the Company began to enter into international partnerships in 2025. Failure to successfully implement and manage international partnerships could result in financial losses and reputational harm. The airline industry also has been and may again be impacted by bankruptcies, mergers, acquisitions, or heightened financial pressures. Further consolidation in the airline industry generally could result in the reduction of fares by other airlines, which could in turn affect the Company's profitability in existing and new markets. If the Company cannot compete with other airlines' offerings or maintain its costs at a competitive level, then its business, financial condition, and results of operations could be materially adversely affected.

**<u>Operational Risks</u>**

***The Company is currently dependent on Boeing as the sole manufacturer of the Company's aircraft. If the MAX aircraft were to become unavailable for the Company's operations, or if the Company were to continue to experience prolonged delivery delays of MAX aircraft, the Company's business plans, strategies, and results of operations could be materially and adversely affected.***

The Boeing MAX aircraft are crucial to the Company's ability to operate and grow its business and fleet modernization initiatives. The Company operates the -8 out of the MAX family of aircraft and is awaiting delivery of the -7 out of the MAX family of aircraft. Deliveries of MAX aircraft from Boeing to the Company are subject to Boeing's production schedules and volumes. Boeing has in the past, and may continue to, experience delays in fulfilling its commitments with regards to delivery of the -8 to the Company as a result of manufacturing challenges. Further, the Company's contractual delivery schedule for the -7 is dependent on the FAA issuing required certifications and approvals to Boeing and the Company. The FAA will ultimately determine the timing of the -7 certification and entry into service, and the Company therefore offers no assurances that current estimations and timelines are correct.

The Company currently operates a higher proportion of the Boeing 737 aircraft than other air carriers in the industry, and therefore may encounter novel hazards, age-related maintenance issues, or airworthiness issues associated with 737 aircraft to a larger degree than other carriers with more diversified fleets. Boeing no longer manufactures versions of the 737 other than the MAX family of aircraft. If the MAX aircraft were to become unavailable for the Company's flight operations, the Company's operations would be materially adversely affected. Further, if the -7 certification is not completed in a timely manner, the Company's growth and network plans could be restricted unless and until it could procure and operate other types of aircraft from Boeing or another manufacturer, seller, or lessor.

***The Company may not be able to procure aircraft in the future in a timely manner or on favorable commercial terms, which could limit the Company's growth or negatively affect the Company's cost structure and competitive position.***

The Company's ability to execute its growth, fleet modernization, and strategic and operational plans may be affected by the timely procurement of additional aircraft on commercially favorable terms. Industry demand for new

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

aircraft may exceed supply, and manufacturers may face production constraints, supply chain shortages, changes in production rates, labor disruptions, or order backlogs that limit availability of aircraft. The Company may also encounter less favorable pricing, reduced delivery slot availability, more restrictive contractual terms, or diminished negotiating leverage with aircraft manufacturers, sellers, or lessors. If the Company is unable to procure additional aircraft on acceptable terms or within planned timeframes, the resulting constraints could negatively affect the Company's ability to meet evolving Customer demands, pursue growth or network expansion opportunities, or replace aircraft planned for retirement, any of which could adversely affect the Company's competitive position, operating results, and financial condition.

***Introducing a new aircraft manufacturer or fleet type could impose significant operational complexities, regulatory requirements, and costs on the Company.***

If the Company's operations, growth, or strategic initiatives were to be dependent upon the introduction of a new aircraft make and model to the Company's fleet, the Company would need to, among other things, (i) develop and implement new maintenance, operating, and training programs; (ii) procure new simulators, tooling, spares, and facilities; (iii) secure extensive regulatory approvals; (iv) implement new technologies; (v) negotiate new supplier, parts-support, and maintenance arrangements; and (vi) negotiate pay and work rules with certain labor unions. The requirements associated with operating a new aircraft make and model could take an extended period of time to fulfill and would likely impose substantial costs on the Company. A shift away from a single fleet type could also add complexity to the Company's operations, present operational and compliance risks, and materially increase the Company's costs. Any of these events would have a material, adverse effect on the Company's business, operating results, and financial condition. The Company could also be materially adversely affected if the pricing or operational attributes of its aircraft were to become less competitive.

***The Company's business is labor intensive, with most Employees represented by labor unions; therefore, the Company could be materially adversely affected in the event of conflict with its Employees or its Employees' representatives.***

The airline business is labor intensive, and for the year ended December 31, 2025, Salaries, wages, and benefits expense represented approximately 47 percent of the Company's operating expenses. As of December 31, 2025, approximately 84 percent of the Company's Employees were represented for collective-bargaining purposes by labor unions, making the Company particularly exposed in the event of labor-related job actions. Employment-related matters (some of which relate to negotiated items) that have impacted the Company's results of operations include hiring/retention rates, attendance, pay rates, outsourcing, work rules, health care costs, and retirement benefits. Although the Company has reached final labor agreements with its twelve unionized Employee groups, the next of which becomes amendable in October 2026, general wage inflation has resulted, and is expected to continue to result, in pressure on the Company's low-cost structure. Renegotiating labor agreements or entering into new labor agreements can require significant costs and extensive bargaining and, in some instances, may not be successful. The Company's results could be materially adversely affected in the event of conflicts or failures to successfully negotiate necessary terms or agreements with its Employees or its Employees' representatives.

***The Company's business is labor intensive; therefore, the Company has been, and could in the future be, adversely affected if it were unable to employ and retain appropriate numbers of qualified Employees to maintain its operations.***

The Company's success depends on its ability to attract and retain appropriate levels of skilled personnel. In connection with the drastic reduction in travel demand due to the pandemic, in 2020 the Company offered voluntary separation and extended time-off programs to Employees. This negatively impacted the Company's ability to staff appropriately when demand for leisure travel returned. Boeing aircraft delivery delays, network optimization efforts, and cost control initiatives have also required the Company to re-evaluate its hiring needs and moderate staffing in line with demand. As a result, the Company offered a voluntary separation program to certain Employees in 2024, and the Company implemented a reduction in workforce in 2025. Staffing-related challenges, particularly any unpredictability in required staffing levels, could continue to occur in certain areas and limit the Company's ability

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

to optimally adjust capacity. The inability to recruit and retain skilled personnel or the unexpected loss of key skilled personnel could continue to adversely affect the Company's operations.

***The Company is currently dependent on a single engine supplier, as well as single suppliers of certain other aircraft parts and equipment; therefore, the Company could be materially adversely affected (i) if it were unable to obtain timely or sufficient delivery of aircraft parts or equipment from Boeing or other suppliers or adequate maintenance or other support from any of these suppliers at commercially reasonable terms, (ii) if Boeing or other suppliers were unable to achieve and/or maintain required regulatory certifications or approvals of their parts or equipment, or (iii) in the event of a mechanical or regulatory issue associated with the Company's aircraft parts or equipment.***

The Company is dependent on Boeing as its sole supplier for many of its aircraft parts. The Company is also dependent on sole or limited suppliers for aircraft engines and certain other aircraft parts, equipment, and services. If Boeing, or other suppliers, were unable or unwilling to timely provide adequate products or support for their products at commercially reasonable terms, were unable to achieve and/or maintain required regulatory certifications or approvals of their parts or equipment, or in the event of a mechanical or regulatory issue associated with engines or other parts or services, the Company's operations could be materially adversely affected. The Company could also be materially adversely affected if the pricing or operational attributes of its aircraft parts or equipment were to become less competitive.

The Company is also dependent on third-party vendors and service providers. Adverse macroeconomic conditions have resulted, and could continue to result, in delays and other performance issues, ceased operations, or even bankruptcies among suppliers, third-party vendors, and service providers. The operations of the Company's third-party vendors and service providers could also be affected by the policies, procedures, and performance of their suppliers, and the Company may not have visibility into this multi-tiered supply chain. Failures of suppliers, third-party vendors, or service providers to timely provide adequate products or support for their products, or otherwise fulfill their commitments to the Company, could materially adversely affect the Company's operations.

***The airline industry has faced on-going security concerns and related cost burdens; further threatened or actual terrorist attacks, war, or other hostilities, even if not made directly on the airline industry, could significantly harm the airline industry and the Company's operations.***

Terrorist attacks, war, or other hostilities, actual and threatened, have from time to time materially adversely affected the demand for air travel and have necessitated increased safety and security measures and related costs for the Company and the airline industry generally. Safety and security measures can create delays and inconveniences, which in turn can reduce the Company's competitiveness against surface transportation for short-haul routes and alternatives to transportation such as videoconferencing, business communication platforms, and the Internet. Additional terrorist attacks, war, or other hostilities, even if not made directly on the airline industry, or the fear of such attacks or other hostilities (including elevated national threat warnings, government travel warnings to certain destinations, travel restrictions, or selective cancellation or redirection of flights due to terror threats) would likely have a further significant negative impact on the Company and the airline industry.

***Interruptions or disruptions in service at one of the Company's core stations have had, and could in the future have, a material adverse impact on its operations.***

In recent years, the Company has increasingly focused on designing its network around core stations in an effort to provide greater connectivity and support operational reliability and recoverability. Significant interruptions or disruptions in service at one or more of the Company's core stations (such as Denver or Chicago-Midway), resulting from air traffic control systems, weather incidents, performance by third-party service providers, interruption of the Company's technology, the availability and location of the Company's crew resources, fuel supplies, or otherwise, have resulted, and could again in the future result, in the cancellation or delay of a significant portion of the Company's flights and, as a result, have had, and could again in the future have, a severe impact on its business, results of operations and financial condition.

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

***The Company's operations have been, and in the future may again be, materially and adversely disrupted by extreme weather events. An inability to quickly and effectively restore operations following adverse weather, a localized disaster, or disturbance in a key geography has adversely and materially impacted, and in the future could again adversely and materially impact, the Company's business, results of operations, and financial condition.***

While the Company operates across a diverse geographic footprint, its operations at times have been adversely and materially impacted by severe weather, such as Winter Storm Fern in January 2026, Hurricane Milton in October 2024, and Winter Storm Elliott in December 2022. Depending on location, the Company's assets and route network have been or could be exposed to ongoing risks arising from a variety of adverse weather conditions or localized natural or manmade disasters such as earthquakes, volcanoes, wildfires (such as the 2023 Maui wildfires and the 2025 Los Angeles wildfires), hurricanes, tropical storms, tornadoes, floods, sea-level rise, severe winter weather, sustained or extreme cold or heat, drought, or other disturbances, actual or threatened. Extreme weather conditions, including increases in the frequency, severity, or duration of severe weather events (whether or not caused by anthropogenic climate change), can disrupt air travel from time to time, ground planes, damage equipment and increase maintenance costs, cause delays and cancellations or other network disruptions, require implementation of weight limitations due to increased temperatures, increase turbulence-related injuries, cause disruptions in staffing, cause increases in fuel consumption to avoid such weather, disrupt the Company's supply chains (including fuel, parts, and service provider disruptions), and otherwise adversely affect the Company's assets, operations, and infrastructure. The Company could incur significant costs to improve the resiliency of its operations, infrastructure, and supply chain, and otherwise prepare for, respond to, and mitigate the potential acute and chronic physical effects of climate change. The Company is not able to predict accurately the materiality of any potential losses or costs associated with the extreme weather events. Prolonged interruptions or disruptions at airports can and do also adversely impact the Company's business and results of operations. The Company also may incur significant costs to reestablish or relocate affected business functions, aircraft, and Employees. Moreover, any resulting economic dislocations could adversely affect demand for the Company's services, resulting in an adverse effect on its business, results of operations, and financial condition.

***The airline industry is made up of inherently complex systems and is affected by many conditions that are beyond its control, which can impact the Company's business strategies and results of operations.***

In addition to the unpredictable economic conditions and fuel costs previously discussed, the Company, like the airline industry in general, is affected by conditions that are largely unforeseeable and outside of its control, including, among others:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• adverse weather and natural disasters and the associated effects on the Company's operations, which have, in certain circumstances, such as Winter Storm Elliott, impacted the Company's operational recovery to a greater degree than other airlines;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in consumer preferences, perceptions, spending patterns, or demographic trends (including, for example, changes in travel patterns due to economic conditions, weather, government restrictions, sequestration, or shutdowns);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actual or potential disruptions in the air traffic control system (including, for example, as a result of FAA system outages or inadequate FAA staffing levels, as the United States has recently seen a shortage of air traffic controllers, resulting in more frequent and prolonged flight delays, limitations on the number of offered flights, and disrupting travel plans across the entire network);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actual or perceived delays at various airports resulting from government restrictions (including, for example, longer wait-times at TSA checkpoints due to inadequate TSA staffing levels);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the competitive environment due to industry consolidation, industry bankruptcies, and other factors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• delays in deliveries of new aircraft (including, for example, due to delays in the manufacturing process, in FAA certification, or due to the closure of the FAA's aircraft registry during government restrictions or shutdowns);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• collective-bargaining requirements and demands;

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reliance on third-party facilities, goods, and/or services essential to its operations and/or business such as airports, de-icing services, fuel supply and delivery, software, and weather data and other critical information;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• outbreaks of disease such as the COVID-19 pandemic;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• laws and regulations, which may change or which may be inconsistent across various jurisdictions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actual or threatened war, terrorist attacks, government travel warnings to certain destinations, travel restrictions, and political instability.

Because airline systems are inherently and unavoidably complex, large or small events, especially when in combination, can create opportunity for a systemic incident. The potential triggers for incidents and failures change constantly because of changing technology, work organization, efforts to eradicate those potential triggers, and other factors. Events or combinations of events such as those described above have had, and could have, a material adverse effect on the Company's business, results of operations, and financial condition.

**<u>Information Technology, Cybersecurity, and Data Privacy Risks</u>**

***The Company is heavily dependent on technology to operate its business and continues to implement substantial changes to its information systems; any failure, disruption, breach, or delay in the Company's information systems or in implementation of necessary changes could materially adversely affect its operations.***

The Company depends heavily on the use of computer systems, hardware, software, technology infrastructure, operational technology, networks, and online sites (collectively, "IT Systems") to run its ongoing operations and support its strategic objectives. These IT Systems include, among others, the Company's website and reservation system; mobile application; flight dispatch and tracking systems; flight simulators; check-in kiosks; aircraft maintenance, planning, and record keeping systems; telecommunications systems; flight planning and scheduling systems; crew scheduling systems; human resources systems; and financial planning, management, and accounting systems. The performance, reliability, and security of the Company's IT Systems are critical to the Company's operations and initiatives. Any failure, disruption, or delay in implementation of the Company's IT Systems could limit or even curtail its growth, delay strategic initiatives, increase its compliance costs, harm its reputation, or reduce its competitive advantage.

In the ordinary course of business, the Company's IT Systems require continuous updates and modifications to support business operations, growth, and changing business strategy or regulatory requirements. These enhancements and upgrades represent significant investments and challenges in terms of costs, human resources, and development of internal controls. Implementation and integration require balancing the introduction of new capabilities with the management of existing systems and present the risk of operational or security inadequacy or interruption. The Company's inability to timely or effectively implement, update, or integrate its IT Systems, could materially affect its business and/or could negatively impact the Company's results of operations and financial performance.

The Company is also reliant upon the performance of third parties for timely and effective implementation and support of many of its technology initiatives, to provide required data and information services, and for maintaining adequate information security measures within the services and/or software they deliver, and such third parties are occasionally not timely or adequate in providing the services required by the Company. If any of the Company's IT Systems or third-party systems were to cease functioning, or if its third-party service providers or data providers were to fail to adequately and timely provide required information or reports, technical support, system maintenance, security, or software upgrades for any of the Company's existing IT Systems, the Company could experience service interruptions, delays, and loss of critical data, which could harm its operations and result in financial losses and reputational damage.

The Company must securely handle high volumes of traffic and operational data, which makes it vulnerable to various security risks and interruptions. The Company has experienced material technology system interruptions and delays that have made its websites and operational systems unavailable or slow to respond, which has prevented the Company from efficiently processing Customer transactions or providing services. Similarly, the Company has

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

experienced operational challenges in connection with severe weather events and associated crew scheduling, such as during and subsequent to Winter Storm Elliott. Any future system interruptions or delays or operational disruptions or delays could reduce the Company's operating revenues and the attractiveness of its services, as well as increase the Company's costs.

The Company's IT Systems or those of third-party service providers could be damaged or interrupted by catastrophic events beyond its control such as fires, floods, earthquakes, tornadoes and hurricanes, power loss, computer and telecommunications failures, acts of war or terrorism, computer viruses, malware, ransomware, security breaches, and similar events or disruptions generally beyond the Company's control. Any of these events could cause system interruptions, delays, and loss of critical data, and could prevent the Company from processing Customer transactions or providing services, which could make the Company's business and services less attractive and subject the Company to liability. Any of these events could damage the Company's reputation and be expensive to remedy.

***The Company is increasingly exposed to cybersecurity attacks and data incidents impacting its IT Systems, or those of the Company's vendors or service providers. Such cybersecurity incidents or data incidents could have a disruptive and material adverse effect on the Company's business, financial position, or results of operations.***

The Company's business depends on both internal and external IT Systems. These IT Systems are essential for daily operations but are exposed to risks like programming errors, software malfunctions, unauthorized access, accidental leaks of sensitive information, denial of service attacks, ransomware, data corruption, business disruptions, outages, security breaches, computer viruses, data loss, scams, theft, insider threats, and human errors. These IT Systems may be subject to increasingly significant attacks by hackers, cybercriminals, nation-states, insiders, or other third parties. Advances in computer capabilities, AI-enhanced attacks, social engineering, phishing, cryptography, inadequate facility security, insider threats, or other technological developments may result in a compromise or breach of the Company's critical operations systems, physical assets, or technology the Company uses to safeguard confidential, personal, or proprietary information. A compromise of the Company's IT Systems or physical assets, or those of a vendor or service provider, could lead to safety incidents, damage to the Company's assets, significant remediation costs and liability, regulatory actions, privacy or securities law violations and related fines, loss of contracts, significant and long-lasting reputational harm, or a failure to meet the Company's contractual obligations. Incidents impacting one system can impact other interconnected systems. For example, cybersecurity incidents impacting the Company's IT Systems or those provided by a vendor or service provider could disrupt the Company's operations and even impact the safe operation of physical assets like aircraft. Any of these outcomes could significantly harm the Company's operations, financial health, and business results.

To operate its business, the Company must receive, process, transmit, and store information related to a number of groups—Customers, Employees, contractors, business partners, and other third parties—and the Company's operations depend upon secure processing, transmission (including over public networks), storage, and retention of that information. As noted above, this subjects the Company to cyber-attacks, which can vary in scope and sophistication, potentially resulting in unauthorized access to its systems or physical assets, data incidents, operational disruptions, and misappropriation of sensitive data. All information processed, stored, and retained by Company or on behalf of Company is subject to the continually evolving risk of intrusion, tampering, theft, or deletion.

The Company has a dedicated cybersecurity team and program, along with support from legal advisors and other resources, focused on current and emerging data security matters. The Company's systems and cybersecurity measures require ongoing monitoring and updating as technologies change, and security could be compromised, personal or confidential information could be misappropriated, or system disruptions could occur. The Company may also incur significant costs to modify, upgrade, or enhance its cybersecurity measures to protect and defend against such attacks and breaches. The Company may not be able to anticipate, detect, or prevent cyber-attacks, security breaches, or data incidents, particularly because the methodologies used by threat actors change frequently or may not be recognized until such attack is launched or for a substantial period thereafter, and because threat

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

actors are increasingly using technologies specifically designed to circumvent cybersecurity measures and avoid detection. Moreover, even with the efforts and investments to protect against cyber-attacks, the Company may not be able to prevent a data breach involving sensitive data. A successful breach of the Company's IT Systems could erode Customer confidence in the Company's digital platforms, security measures, data protection, resiliency, and services. Beyond operational disruptions, such incidents could result in reputational damage, loss of Customer trust, regulatory investigations and fines, or individual or class action lawsuits, all of which could have a material adverse effect on the Company's financial condition and results of operations. See "Business—Regulation—Data Privacy and Cybersecurity Regulation."

In the ordinary course of its business, the Company also provides certain confidential, proprietary, and personal information, intellectual property, and safety information to third parties. While the Company seeks to obtain assurances that these third parties will protect this information and their systems in accordance with legal requirements and industry standards, there is a risk that the security of systems and data held by third parties could be compromised. A compromise of data stored by third-party systems could adversely affect the Company's reputation, disrupt its operations, and result in litigation against the Company or the imposition of penalties from regulators. In addition, these third-party incidents or failures could be costly and take time to remediate.

The Company offers the ability for some of its Employees to work remotely and, with that, maintaining a remote work environment significantly increases the risk of cyber incidents and events, such as computer viruses and security breaches, due to increased available attack vectors. Targeted attacks have also increased but have thus far been mitigated by preventative, detective, and responsive measures put in place by the Company.

Although the Company has not experienced cyber incidents that are, individually or in the aggregate, material, the Company and certain of its vendors and service providers have experienced cyber-attacks and cybersecurity incidents in the past, which have thus far been mitigated by preventative, detective, and responsive measures.

***The Company is expanding its use of AI and machine-learning. Any failure in the Company's AI implementation strategy, compliance with regulations, or failure to otherwise manage the risks related to AI technologies effectively could materially adversely affect its operations, reputation, and/or financial position.***

The Company is expanding its use of AI and machine-learning to carry out elements of its business strategy. The implementation of AI technologies also presents significant operational, legal, and competitive risks to the Company. Although the Company believes it diligently evaluates, governs, tests, and deploys AI-related technologies, the Company could face numerous AI-related challenges, such as cybersecurity vulnerabilities, algorithmic biases or errors, evolving regulatory requirements across jurisdictions, and potential competitive disadvantage if the Company's competitors deploy AI technologies more quickly or more successfully. The complex and evolving regulatory landscape surrounding AI technologies, including regarding violations of intellectual property rights and data privacy concerns, creates additional compliance challenges and potential liability. For example, emerging regulations, state laws, and other proposed legislation around AI may require companies that develop or deploy AI systems to establish formal governance structures and internal controls, including designated oversight personnel, documented risk assessment procedures, and regular compliance reviews of their AI systems. While the Company expects its AI adoption to enhance its operations, there can be no assurance of its effectiveness or that it will deliver the anticipated benefits. Furthermore, the Company's use of AI could result in reputational damage, legal exposure, or loss of Customer confidence if not properly deployed or managed. Moreover, changes to the Company's technology and systems could also expose the Company to intellectual property risks, such as allegations of infringement of third-party patents or copyrights. Defending against allegations could involve significant fees and resources. If the Company is found to infringe upon third-party intellectual property rights, the Company may be liable for damages.

**<u>Legal, Regulatory, Compliance, and Reputational Risks</u>**

***The Company is subject to extensive government regulation that may disrupt or necessitate modifications to the Company's operations, business plans, and strategies, increase the Company's operating costs, or otherwise limit the Company's ability to conduct business.***

The FAA promulgates and enforces regulations affecting the airline industry and exercises extensive regulatory oversight of the Company's operations. For example, in November 2025 during the partial government shutdown, the FAA issued an emergency order mandating an industry-wide reduction in flights at 40 major U.S. airports. The FAA from time to time also issues orders or directives relating to the maintenance and operation of aircraft. FAA orders and directives can be issued with little or no notice, and in certain instances, require the temporary grounding of aircraft, such as the FAA's March 2019 grounding of all Boeing 737 MAX aircraft, and/or the responsive investment of operational and financial resources. The issuance of new FAA regulations, regulatory amendments, or orders or directives could result in flight schedule adjustments and groundings or delays in aircraft deliveries, as well as lower operating revenues, operating income, and net income due to a variety of factors, including, among others, (i) lost revenue due to flight cancellations and operational disruptions as a result of a smaller operating aircraft fleet, (ii) the lack of ability to make corresponding reductions in expenses because of the fixed nature of many expenses, and (iii) possible negative effects on Customer confidence and airline choice.

As discussed under "Business - Regulation," airlines are also subject to other extensive regulatory requirements. These requirements often impose substantial costs on airlines. The Company's strategic plans and results of operations could be negatively affected by changes in law and future actions taken by domestic and foreign governmental agencies having jurisdiction over the Company's operations, including, but not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increases in airport rates and charges;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limitations on airport gate capacity or use of other airport facilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limitations on route authorities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actions and decisions that create difficulties in obtaining access at slot-controlled airports (a "slot" is the right of an air carrier, pursuant to regulations of the FAA or local authorities, to operate a takeoff or landing at certain airports);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actions and decisions that create difficulties in obtaining operating permits and approvals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes to environmental regulations, including mandates affecting the usage of SAF and enhanced emissions and climate reporting obligations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mandates on and regulation of existing products and services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• new or increased taxes or fees, such as with respect to potential increases to the federal corporate income tax rate, and such as those contained in the Inflation Reduction Act, including a potential corporate alternative minimum tax or taxes imposed on share repurchases, which may affect the Company's decisions with respect to capital markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes to laws that affect the services that can be offered by airlines in particular markets and at particular airports;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• restrictions on competitive practices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in laws that increase costs for safety, security, compliance, or other Customer Service standards;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in laws that may limit or regulate the Company's ability to promote the Company's business or fares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in laws that could affect the value of the Company's existing contracts or agreements, such as its co-branded credit card agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• airspace closures or restrictions, such as restrictions on operations in markets where certain wireless telecommunications systems may cause interference with certain aircraft avionics;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• grounding of commercial air traffic by the FAA;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the adoption of more restrictive locally imposed noise regulations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expanded compliance burdens, costs, and enforcement risks related to evolving data privacy and cybersecurity laws and regulations.

***Airport capacity constraints and air traffic control inefficiencies have limited and could continue to limit the Company's growth.***

Almost all commercial service airports are owned and/or operated by units of local or state governments. Airlines are largely dependent on these governmental entities to provide adequate airport facilities and capacity at an affordable cost. In order to operate efficiently, as well as to add service in current and new markets, the Company must be able to maintain and/or obtain space and facilities at desirable airports with adequate infrastructure. Airport space, facility, and infrastructure constraints may prevent the Company from maintaining existing service and/or implementing new service in a commercially viable manner.

Similarly, the federal government singularly controls all U.S. airspace, and airlines are dependent on the FAA controlling that airspace in a safe and efficient manner. The current air traffic control system is mainly radar-based, supported in large part by antiquated equipment and technologies, and heavily dependent on skilled personnel. As a result, the air traffic control system may not be able to effectively keep pace with future air traffic growth. The FAA has received funds to support upgrades to the air traffic control system, but ongoing modernization efforts continue to face bureaucratic and budgetary constraints, and the FAA may not be able to secure adequate additional funding to implement sufficient system upgrades in a timely manner. The FAA's protracted transition to modernized air traffic control systems and newer technologies has and may continue to adversely impact airspace capacity and the overall efficiency of the system, resulting in limited opportunities for the Company to grow, longer scheduled flight times, increased delays and cancellations, and increased fuel consumption and aircraft emissions. For example, due to air traffic control staffing challenges, government agencies have had to implement short-term capacity constraints during peak travel periods or adverse weather conditions in certain markets, resulting in delays and disruptions of air traffic. Additionally, telecommunications outages such as the 2025 Newark outages and September 2025 Dallas outages have caused air traffic controllers to lose radar and communications, resulting in ground stops, delays, and cancellations. The continuation of these air traffic control disruptions and constraints or the FAA's inability to meet staffing needs on a long-term basis may have a material adverse effect on the Company's operations.

***The Company is subject to various environmental requirements and risks, including increased regulation, changing consumer preferences, physical, environmental, and climate risks, and risks associated with climate change; the cost of compliance with more stringent environmental regulations, failure to comply with environmental regulations, or failure to otherwise manage the risks of climate change effectively could have a material adverse effect on the Company's results of operations.***

The Company is subject to changing federal, state, local, and international laws and regulations relating to the protection of the environment, including those relating to aircraft and ground-based emissions, discharges to water systems, safe drinking water, and the management of hazardous substances and waste materials. In addition, while the Company cannot predict what requirements may be imposed in the future or the timing with respect to the same, federal, state, local, and international legislative and regulatory bodies in recent years have generally increased focus on climate change and reducing GHG, including by requiring disclosure of emissions and climate-related risks, and may continue to do so. For more detail, see "Business–Regulation–Environmental Regulation." Future policy, legal, regulatory, or other market developments could require the Company to reduce its emissions, increase its usage of SAF and other forms of lower carbon energy, modify its supply chain practices or aspects of its operations, make capital investments to purchase specific types of equipment or technologies, secure carbon offset credits, disclose or report additional GHG information, or otherwise incur additional costs related to regulatory compliance and climate objectives. Additional regulation could result in increased regulatory or permitting requirements for the Company from multiple jurisdictions. Further, various state agencies have proposed regulation that would subject fossil jet fuel to lower emissions standards. Proposal or adoption of such obligations could increase the demand for and the costs of the limited supply of SAF currently available and could result in increased costs of fossil jet fuel. Until the timing, scope, and extent of such future policy, legal, regulatory, or other market developments become known, the Company cannot predict their effect on the Company's cost structure or its operating results. Violations of environmental and climate change-related laws and regulations could lead to significant fines and penalties and reputational harm. The Company could also face increased risks of litigation resulting from any enhanced disclosure requirements related to climate change.

Concern among consumers of the impacts of climate change may mean some customers choose to fly less frequently or fly on an airline they perceive as operating in a manner that is more sustainable to the climate, and customers may choose to use alternatives to travel, such as virtual meetings and workspaces. Greater development of high-speed rail in markets now served by short-haul flights could provide passengers with lower-carbon alternatives to flying. Longer-term changes in weather patterns could adversely impact any of the Company's destination cities and, as a result, alter Customers' travel behavior. The Company's collateral to secure loans, including in the form of aircraft, could lose value as customer demand shifts and economies move to lower-carbon alternatives, which may increase the Company's financing costs. In addition, major financial institutions have announced GHG emissions reductions targets for their financed activities in the aviation sector, and while these commitments may be in flux, financing restrictions related to emissions reductions targets could impact the Company's ability to access capital on advantageous terms now or in the future. To the extent that the Company's climate targets are not perceived to align with those of its lenders, the Company's access to credit may be adversely impacted.

***The Company is subject to risks related to its sustainability goals and disclosures, which may affect stakeholder sentiment and the Company's reputation and brand.***

The Company has voluntarily set near- and long-term environmental sustainability plans and goals, and any failure or perception of failure to meet or adequately progress against its sustainability plans or goals, which are often aspirational, or any modifications to such goals could adversely affect the Company's reputation and brand. The Company's sustainability goals are subject to risks and uncertainties related to the Company's ability to successfully implement its business strategy, effectively respond to changes in market dynamics, and realize the anticipated benefits and associated cost savings of its actions.

The achievement of the Company's plans and goals is materially dependent on the performance of third parties and government action, and these goals could be adversely affected by changes in third-party expectations, methodologies, and priorities, which are rapidly evolving. For example, the Company plans to diversify its sources of jet fuel through increasing the volumes of SAF in its operations. The cost of SAF may be prohibitively expensive without appropriate government support, policies, and incentives (including tax credits). The Company may have binding SAF purchase commitments that extend beyond various incentives currently in place, and the presidential administration may take action to revise, repeal, or otherwise modify existing SAF incentives, which could impact the Company's operations. The Company may also face pressure from local and state governments as they continue advancing their own, sometimes conflicting, climate-related policies. Heightened competition for alternative fuel sources like SAF may impact the Company's ability to negotiate contracts with third parties at commercially reasonable and economically favorable terms. The Company's achievement of its sustainability goals (whether mandated or voluntary) may also depend on technology developments that have not yet occurred or been implemented in a commercially feasible and cost-competitive manner. Failures or delays in sufficient SAF production and delivery, or ceased operations or bankruptcies of the Company's counterparties, could inhibit the Company's ability to meet its stated goals. Additionally, to the extent that the Company may seek to achieve its climate goals and obligations through the use of carbon offsets, it may be exposed to increased costs, disclosure requirements, and risks related to third parties associated with the procurement of such offsets.

The Company makes certain disclosures regarding sustainability, many of which are based on estimates, assumptions, and timelines which are subject to high levels of uncertainty and inherently difficult to assess in advance. There is no guarantee that Customers, regulators, or other stakeholders will not object to the Company's use of certain models and accounting methods. Enhanced mandatory climate-related disclosures could lead to reputational or other harm with Customers, regulators, investors, or other stakeholders. Statements or initiatives with respect to sustainability matters are also increasingly subject to heightened scrutiny from the public and governmental authorities. The Company may face pressure from Customers, stakeholders, and financial institutions to change its policies, and such stakeholders may have different, conflicting expectations. Certain regulators, such as the SEC and various state agencies, as well as nongovernmental organizations and other private actors have filed lawsuits under various securities and consumer protection laws alleging that certain sustainability statements, goals, or standards were misleading, false, or otherwise deceptive. Alternatively, the Company could face criticism from

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

certain "anti-ESG" parties for making environmental or social commitments or pursuing certain environmental or social initiatives that are alleged to be political or polarizing in nature, which could adversely affect the Company's reputation, business, financial performance, market access, and growth.

The Company could face increased litigation risks relating to alleged direct or indirect climate-related damages resulting from the Company's operations, statements alleged to have been made by the Company or others in the aviation industry regarding climate change risks, or in connection with any future voluntary or mandatory disclosures the Company may make regarding reported emissions. The Company, as a consumer-facing business, may also face public relations criticism (such as boycotts or negative publicity campaigns) related to its sustainability efforts and policies. Any damage to the Company's reputation or brand as a result of such litigation, public criticism, or failure to meet or maintain its sustainability plans or goals could adversely affect the Company's operations, financial condition, and future results.

***The Company's future results may suffer if it is unable to effectively manage its current and contemplated international operations or Extended Operations ("ETOPS").***

The Company's international flights are subject to CBP-mandated procedures, which can affect the Company's operations, costs, and Customer Experience. The Company has made significant investments in facilities, equipment, and technologies at certain airports in order to improve the Customer Experience and to assist CBP with its inspection and processing duties; however, the Company is not able to predict the impact, if any, that various CBP measures or the lack of CBP resources will have on Company revenues and costs, either in the short-term or the long-term.

International flying requires the Company to modify certain processes, as the airport environment can be dramatically different in certain international locations with respect to, among other things, common-use ticket counters and gate areas, passenger entry requirements (including health requirements), local operating requirements, staffing, infrastructure, and cultural preferences. Certain international routes served by the Company are also subject to specific aircraft equipage requirements and unique consumer behavior. Route-specific equipage requirements and unique consumer behavior, together or individually, may (i) restrict the Company's flexibility when scheduling and routing aircraft and crews; (ii) require the Company to modify its policies or procedures; and (iii) impact the Company's operational performance, costs, and Customer Experience. In addition, international flying exposes the Company to certain foreign currency risks to the extent the Company chooses to, or is required to, transact in currencies other than the U.S. dollar. To the extent the Company seeks to serve additional international destinations in the future, or to renew its authority to serve certain routes, it may be required to obtain necessary authority from the DOT and/or approvals from the FAA, as well as any applicable foreign government entity.

The Company's operations in non-U.S. jurisdictions may subject the Company to the laws of those jurisdictions rather than, or in addition to, U.S. laws. Laws in some jurisdictions differ in significant respects from those in the United States, and these differences can affect the Company's ability to react to changes in its business, and its rights or ability to enforce rights may be different than would be expected under U.S. laws. Furthermore, enforcement of laws in some jurisdictions can be inconsistent and unpredictable, which can affect both the Company's ability to enforce its rights and to undertake activities that it believes are beneficial to its business. As a result, the Company's ability to generate revenue and its expenses in non-U.S. jurisdictions may differ from what would be expected if U.S. laws governed these operations. Although the Company has policies and procedures in place that are designed to promote compliance with the laws of the jurisdictions in which it operates, a violation by the Company's Employees, contractors, or agents or other intermediaries could nonetheless occur. Any violation (or alleged or perceived violation), even if prohibited by the Company's policies, could have an adverse effect on the Company's reputation and/or its results of operations.

In 2019, the Company began service to Hawaii after receiving approval from the FAA for ETOPS, a regulatory requirement to operate between the U.S. mainland and the Hawaiian Islands. The Company is subject to additional, ongoing, ETOPS-specific regulatory and procedural requirements, which present operational and compliance risks to the Company's business, including costs associated therewith.

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

The Company has entered into interline partnership agreements for international flights, including with Icelandair, China Airlines, EVA Air, Philippine Airlines, Condor, and Turkish Airlines. The Company is also actively pursuing partnerships with other international carriers for transpacific and transatlantic service. There is no assurance that the Company will be able to successfully execute its strategies and achieve its previously announced international partnership goals, and failure to do so may adversely affect the Company's operating results.

***The Company's plans to develop commercial relationships with airlines in other parts of the world may not produce the results or returns it expects.***

The Company continues its initiative to expand its network and develop strategic relationships with a number of airlines through interline agreements, and potentially other forms of cooperation and support. These relationships involve significant challenges and risks, including that cooperation agreements may be subject to ongoing approval, review, and renewal requirements, may not generate the expected financial results, and may distract management from the Company's operations or other strategic options. The Company faces competition in forming and maintaining these commercial relationships since there are a limited number of potential arrangements and other airlines may be looking to enter into similar relationships. The Company's inability to form or maintain these relationships, or inability to form as many relationships as the Company's competitors or in less advantageous geographic regions as its competitors, could adversely affect the Company's business. The Company may be dependent on these other carriers for significant aspects of its network in the regions in which they operate. While the Company expects to work closely with these carriers, the Company will not have control over their operations or business methods. To the extent that the operations of any of these carriers are disrupted over an extended period or their actions have a significant adverse effect on the Company's operations, the Company's results of operations could be materially adversely affected. If the Company's commercial arrangements with any of these partners are not maintained, its business and results of operations could be materially adversely affected.

***The Company is currently subject to regulatory actions and pending litigation, and if judgment, penalties, or fines were to be rendered against the Company, such judgment, penalties, or fines could adversely affect the Company's operating results.***

As discussed below under "Legal Proceedings," the Company is subject to regulatory actions and pending litigation. Regardless of merit, these litigation matters and any potential future claims against the Company may be both time consuming and disruptive to the Company's operations and cause significant expense and diversion of management attention. Should the Company fail to prevail in these or other matters, the Company may be faced with significant monetary damages or injunctive relief that could materially adversely affect its business and might materially affect its financial condition and operating results and could cause reputational harm.

***Conflicting federal, state, and local laws and regulations may impose additional requirements and restrictions on the Company's operations, which could increase the Company's operating costs, result in service disruptions, and increase litigation risk.***

Airlines are subject to extensive regulatory and legal requirements at the federal, state, and local levels that require substantial compliance costs and that may be inconsistent with each other. These laws could affect the Company's relationship with its workforce and cause its expenses to increase without an ability to pass through these costs. In recent years, the airline industry has experienced an increase in litigation asserting the application of state and local employment laws. Application of state and local laws to the Company's operations may conflict with federal laws—or with the laws of other states and local governments—and may subject the Company to additional requirements and restrictions. Moreover, application of these state and local laws may result in operational disruption, increased litigation risk, and negative effects on the Company's collective-bargaining agreements. Adverse litigation results in any of these cases could adversely impact the Company's operational flexibility and result in the imposition of damages and fines, which could potentially be significant.

***The Company's reputation and brand could be harmed if it were to experience significant negative publicity through social media or otherwise.***

The Company operates in a public-facing industry with significant exposure to social media, and failure to maintain the Company's reputation or brand could adversely affect its business, financial performance, market access, and growth. Negative publicity, whether or not justified, can spread rapidly through social media. The Company's reputation or brand, as well as its Customer and other stakeholder relationships, could be adversely impacted as a result of, among other things, (i) Customer perceptions of the Company's strategic initiatives; (ii) Customer perceptions of the Company's advertising campaigns, sponsorship arrangements or marketing programs; (iii) Customer perceptions of the Company's use of social media; (iv) Customer and other stakeholder perceptions of statements made by the Company, its Employees and executives, agents, any industry trade associations, or other third parties; or (v) public pressure from certain investors or policy groups to change the Company's policies. Negative consumer perception of the safety of air travel, including due to public reports and coverage of specific accidents, may also adversely impact the Company's reputation and brand. To the extent that the Company is unable to respond timely and appropriately to negative publicity, including as related to its strategic initiatives, the Company's reputation and brand can be harmed. Damage to the Company's overall reputation and brand could have a negative impact on its financial results and require additional resources for the Company to rebuild its reputation.

***The Company's business has been, and could in the future be, negatively affected as a result of actions of activist shareholders, and such activism could adversely affect the strategic direction and business results of the Company.***

Publicly traded companies are increasingly subject to campaigns by activist shareholders advocating corporate actions such as operational, governance, management or social changes, financial restructurings, increased borrowings, special dividends, stock repurchases, or sales of assets or entire companies to third parties or to the activist shareholders themselves. The Company has been and may again be subject to actions from activist shareholders or others that may not align with its business strategies or may not be in the best interests of all of its Shareholders. Actions taken by the Board and management in seeking to maintain constructive engagement with certain Shareholders may not be successful to prevent the occurrence of shareholder activist campaigns or changes that adversely affect the strategic direction or business results of the Company.

Responding to actions by activist shareholders has been, and may in the future be, costly and time-consuming and diverts the attention of the Board, management team, and Employees from the management of the Company's operations and the pursuit of its business strategies. Further, actions of activist shareholders may cause fluctuations in the Company's stock price based on temporary or speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of its business. Activist shareholder initiatives and perceived uncertainties as to the Company's future direction, strategy, or leadership created as a consequence of such initiatives may be exploited by the Company's competitors or result in the loss of potential business opportunities and make it more difficult to attract and retain investors, Customers, Employees, qualified directors and officers, and business partners. Changes to the Company's business as a result of or in response to shareholder activism may not produce the anticipated economic benefits and may harm its reputation with Customers, Employees, and others, with related adverse economic consequences. Also, the Company has incurred, and may in the future incur, significant expenses related to activist shareholder matters (including, without limitation, legal fees, fees for financial advisors, fees for public relation advisors, and proxy solicitation expenses). If individuals with a specific agenda are elected or appointed to the Board, it may adversely affect the Company's ability to effectively and timely implement its strategic plans to maximize value for Shareholders. Furthermore, if individuals are elected or appointed to the Board who do not agree with the Company's strategic plan, the ability of the Board to function effectively could be adversely affected. As a result, activist shareholder campaigns could adversely affect the Company's business, results of operations, financial condition, and share price.

In connection with any activist campaign, the Company may choose to initiate, or may become subject to, litigation, which could serve as a further distraction to the Board, management, and Employees and require the Company to incur significant additional costs.

The Company cannot predict, and no assurances can be given as to, the consequences of the settlement of prior activism or the outcome or timing of any matters relating to the foregoing actions by activist shareholders and its responses thereto or the ultimate effects on its business, liquidity, financial condition, or results of operations.

***The Company has adopted certain provisions in its Bylaws that could increase costs to bring a claim, discourage claims, limit the ability of the Company's Shareholders to bring a claim, or limit the ability of the Company's Shareholders to bring a claim in a judicial forum viewed by the Shareholders as more favorable for disputes with the Company or the Company's directors, officers, or other Employees.***

The Company's Bylaws provide that, unless the Company consents in writing to the selection of an alternative forum, the United States District Court for the Northern District of Texas or, if such court lacks jurisdiction, the Texas Business Court located in Dallas County, Texas, will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (a) any derivative action or proceeding brought on behalf of the Company; (b) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, or other Employee of the Company to the Company or the Company's Shareholders; (c) any action asserting a claim against the Company or any director, officer, or other Employee of the Company pursuant to any provision of the Company's Restated Certificate of Formation or Bylaws (as either may be amended from time to time) or the Texas Business Organizations Code ("TBOC"); and (d) any other action asserting a claim against the Company or any director, officer, or other Employee of the Company constituting an "internal entity claim" under the TBOC. Each Shareholder is deemed to have waived any right it may have to a trial by jury in any legal action, proceeding, cause of action, or counterclaim concerning any internal entity claim and, to the fullest extent permitted by applicable law, in any other claim, action, or proceeding against the Company or any director, officer, or other Employee of the Company.

The Company's Bylaws further provide that, as permitted by the TBOC, no shareholder (as defined by the TBOC) may institute or maintain a derivative proceeding unless that shareholder beneficially owns at least three (3) percent of the outstanding shares of the Company.

The forum selection, waiver of jury trial, and derivative proceedings threshold provisions may increase costs to bring a claim, discourage claims, limit a Shareholder's ability to bring a claim, or limit a Shareholder's ability to bring a claim in a judicial forum that such Shareholder finds favorable for disputes with the Company or the Company's directors, officers, or other Employees, which may discourage such lawsuits against the Company or the Company's directors, officers, and other Employees. Alternatively, if a court were to find any of the provisions contained in the Company's Bylaws to be inapplicable or unenforceable in an action, the Company could incur additional costs associated with resolving such actions.

**Cybersecurity Risk Management and Strategy** 

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

**Risk Assessment and Management**

The Company is increasingly dependent on the use of complex technology and systems to run its operations and support its strategic objectives. These technologies and systems include, among others, the Company's website and reservation system; mobile application; flight dispatch and tracking systems; flight simulators; check-in kiosks; aircraft maintenance, planning, and record keeping systems; telecommunications systems; flight planning and scheduling systems; crew scheduling systems; human resources systems; and financial planning, management, and accounting systems. Additionally, the Company must receive and process certain confidential or personal information related to its Customers and Employees to run its business, and the Company's operations depend upon secure collection, processing, retention, and transmission of such information. Therefore, the performance, reliability, and security of the Company's technology infrastructure and information systems are critical to the Company's operations and initiatives.

The Company has an enterprise risk management ("ERM") program to identify, evaluate, and manage risks. Cybersecurity risks are evaluated alongside other critical business risks under the ERM program to align cybersecurity efforts with the Company's broader business goals and objectives. The Company believes that integrating cybersecurity risks into its ERM program fosters a proactive and holistic approach to cybersecurity, which helps safeguard the Company's operations, financial condition, and reputation in an ever-evolving threat landscape.

The Company maintains a cybersecurity program that is designed to identify, protect from, detect, respond to, and recover from cybersecurity threats and risks, and protect the confidentiality, integrity, and availability of its information systems, including the information residing on such systems. The National Institute of Standards and Technology Cybersecurity Framework helps the Company inform its cybersecurity agenda and prioritize its cybersecurity activities. The Company takes a risk-based, threat-informed approach to cybersecurity, which begins with the identification and evaluation of cybersecurity risks or threats that could affect the Company's operations, finances, legal or regulatory compliance, or reputation. Once identified, cybersecurity risks and related mitigation efforts are evaluated and prioritized based on their potential impact, likelihood, velocity, and vulnerability, considering both quantitative and qualitative factors. Risk mitigation strategies are developed and implemented based on the specific nature of each cybersecurity risk or threat. These strategies include, among others, the application of cybersecurity policies and procedures, implementation of administrative, technical, and physical controls, and Employee training, education, and awareness initiatives. The Company's cybersecurity program also includes a Security Operations Center ("SOC") that conducts ongoing monitoring of networks and systems for potential signs of suspicious activity. The SOC is a centralized function that monitors security alerts to initiate triage, verification, and remediation activities. Additionally, the Company's cybersecurity program provides mechanisms for Employees to report any unusual or potentially malicious activity they observe. The Company tracks key performance indicators and cybersecurity metrics to evaluate the efficacy of its cybersecurity controls and practices. Further, the Company's cybersecurity program is periodically reviewed by its Chief Information Officer ("CIO") and Chief Information Security Officer ("CISO" and, together with the CIO, the Company's "Cybersecurity Leaders") and adjusted in an effort to maintain the program's agility and responsiveness as circumstances evolve, new cybersecurity threats emerge, and regulations change.

**Incident Response** 

The Company has a dedicated cybersecurity incident response team responsible for managing and coordinating the Company's cybersecurity incident response efforts. This team collaborates closely with other internal teams as well as with external experts such as legal advisors, communication specialists, and other key stakeholders, as appropriate, in identifying, protecting from, detecting, responding to, and recovering from cybersecurity incidents. Cybersecurity incidents that meet certain thresholds are escalated to the Cybersecurity Leaders and cross-functional teams on an as-needed basis for support and guidance. Additionally, this team tracks cybersecurity incidents to help identify and analyze them. The Company maintains a cybersecurity incident response plan to prepare for and respond to cybersecurity incidents. The incident response plan includes standard processes for reporting and

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

escalating cybersecurity incidents, as appropriate, to senior management, the Audit Committee, and the Board. Additionally, the Company conducts at least one cybersecurity tabletop exercise on an annual basis, where members of a cross-functional team engage in a simulated cybersecurity incident scenario. This preparedness exercise is intended to provide hands-on training for the participants and helps the Company assess its cybersecurity response plan and its processes and capabilities in addressing cybersecurity threats.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**Use of Third Parties**

*Cybersecurity Service Providers and Third-Party Consultants*. The Company engages cybersecurity consultants, assessors, and other third parties to assess and enhance its cybersecurity practices. These third parties conduct assessments, penetration testing, and vulnerability evaluations to help identify potential weaknesses and recommend improvements. Additionally, the Company leverages a number of third-party tools and technologies as part of its efforts to enhance cybersecurity functions, such as a managed security service provider to augment the Company's dedicated SOC team, an endpoint detection and response system for continuous monitoring, detection, and response capabilities, and a security information and event management solution to automate real-time threat detection, investigation, and prioritization of high-fidelity alerts.

*Oversight of Third-Party Service Providers*. The Company also uses third-party service providers to support its operations and many of its technology initiatives. The Company evaluates third-party service providers from a cybersecurity risk perspective, which may include an assessment of that service provider's cybersecurity posture and/or a recommendation of specific mitigation activities. Following an evaluation, the Company determines and prioritizes service provider risk based on potential threat impact and likelihood, and such risk determinations drive the level of due diligence and ongoing compliance monitoring required for each service provider.

**Risks from Material Cybersecurity Threats**

As of the date of this report, the Company has not identified any cybersecurity threats that have materially affected or are reasonably likely to have a material effect on the Company's business strategy, results of operations, or financial condition. Although the Company has not experienced cybersecurity incidents that are individually, or in the aggregate, material, the Company and its service providers have experienced cyber-attacks in the past, which the Company believes have thus far been mitigated by preventative, detective, and responsive measures put in place. For a detailed discussion of the Company's cybersecurity related risks, see "Item 1A. Risk Factors—Information Technology, Cybersecurity, and Data Privacy Risks."

**Cybersecurity Governance** 

**Board Oversight**

The Board is responsible for overseeing management's assessments of major risks facing the Company and for reviewing options to mitigate such risks. The Board's oversight of major risks, including cybersecurity risks, occurs at both the full Board level and at the Board committee level through the Audit Committee.

*The Board*. The Chief Executive Officer, the Chief Operating Officer, the Chief Financial Officer, members of senior management, and other personnel and advisors, as requested by the Board, report on the Company's financial, operating, and commercial strategies, as well as major related risks, which may include cybersecurity risks, at regularly scheduled meetings of the Board. Based on these reports, the Board may request follow-up information and presentations to address any specific concerns and recommendations. Additionally, the Audit Committee has opportunities to report regularly to the entire Board and review with the Board any major issues that arise at the committee level, which may include cybersecurity risks.

*The Audit Committee.* The Audit Committee reviews with management the Company's technology and cybersecurity frameworks, policies, programs, opportunities, and risk profile as needed at its regularly scheduled meetings. The Company's CIO, CISO, members of the cybersecurity team, or other advisors, as requested by the Audit Committee, report periodically on the Company's technology, data protection, and cybersecurity strategies

and risks. Cybersecurity topics are presented to the Audit Committee on a periodic basis and generally highlight any significant cybersecurity incidents, the cyber threat landscape, cybersecurity program enhancements, cybersecurity risks and related mitigation activities, and any other relevant cybersecurity topics. Management believes that this regular cadence of reporting helps to provide the Audit Committee with an informed understanding of the Company's dynamic cybersecurity program and threat landscape. As needed, the Audit Committee reviews with management the Company's business continuity and disaster recovery plans and capabilities and the effectiveness of the Company's escalation procedures. Based on these management reports, the Audit Committee may request follow-up information and presentations to address any specific concerns and recommendations. In addition to this regular reporting, cybersecurity risks or threats may also be escalated on an as-needed basis to the Audit Committee.

**Management's Role**

The Company has a dedicated cybersecurity organization within its technology department that focuses on current and emerging cybersecurity matters. The Company's cybersecurity function is led by the Company's CISO, who reports to the Company's CIO. The Cybersecurity Leaders are actively involved in assessing and managing cybersecurity risks. They are responsible for implementing cybersecurity policies, programs, procedures, and strategies. The responsibilities and relevant experience of each of the Cybersecurity Leaders are listed below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Executive Vice President and CIO provides leadership for the Company's technology department. The CIO holds an undergraduate degree from Cornell University and has served in various roles in information technology for over 20 years, including Senior Vice President, Vice President, Senior Director, Manager, and Consultant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The CISO is responsible for leading the Company's cybersecurity strategy and department, as well as the protection of data and assets across the Company's facilities, airports, and aircraft. The CISO has served in various roles in cybersecurity for over 19 years. The CISO earned a Bachelor of Business Administration in Management Information Systems from The University of Oklahoma and holds a Certified Information Systems Security Professional certification. The CISO also participates in the Aviation Information Sharing and Analysis Center Board and is the Vice Chair of the Cybersecurity Council at Airlines for America.

The Company's cybersecurity department is comprised of teams that engage in a range of cybersecurity activities such as threat intelligence, incident response, security operations, vulnerability management, risk and compliance and security engineering. These teams conduct vulnerability management and penetration testing to identify, classify, prioritize, remediate, and mitigate vulnerabilities. Leaders from each team regularly meet with the Cybersecurity Leaders to provide visibility of relevant issues and seek alignment with strategy. As noted above under "Incident Response," the Company's cybersecurity incident response plan includes standard processes for reporting and escalating cybersecurity incidents, as appropriate, to senior management, the Audit Committee, and the Board. Cybersecurity incidents that meet certain thresholds are escalated to the Cybersecurity Leaders and cross-functional teams on an as-needed basis for support and guidance. The Company's incident response team also coordinates, as needed, with external legal advisors, communication specialists, and other key stakeholders.

**Aircraft** 

Southwest operated a total of 803 Boeing 737 aircraft as of December 31, 2025, of which 82 and 15 were under operating and finance leases, respectively. The following table details information on the 803 aircraft as of December 31, 2025:

&nbsp;&nbsp;&nbsp;&nbsp;(a)See Note 7 to the Consolidated Financial Statements for more information on the Company's lease transactions.

&nbsp;&nbsp;&nbsp;&nbsp;(b)In January 2026, the Company completed retrofits on its -700 fleet to reduce the number of seats to 137 in connection with its implementation of extra legroom seating.

In second quarter and fourth quarter 2025, the Company entered into supplemental agreements with Boeing relating to its contractual order book for -7 and -8 aircraft. These agreements provide flexibility in support of the Company's growth plans and fleet modernization and include certain confidential credits and other concessions provided to the Company by Boeing. The delivery schedule below reflects contractual commitments, although the timing of future deliveries could be affected by any potential or prolonged delays in the manufacturing process or with the -7 certification. The Company retains significant flexibility to manage its fleet size, including opportunities to accelerate fleet modernization efforts if growth opportunities do not materialize.

As of December 31, 2025, the Company had firm deliveries and options for -7 and -8 aircraft as follows:

---

|  | 269 | (a) | 196 | (b) | 152 | (b) | 617 |  |

(a) The delivery timing for the -7 is dependent on the FAA issuing required certifications and approvals to Boeing and the Company. The FAA will ultimately determine the timing of the -7 certification and entry into service, and the Company therefore offers no assurances that current estimations and timelines are correct.

(b) The Company has flexibility to designate firm orders or options as -7s or -8s, upon written advance notification as stated in the contract.

(c) The Company has included the remaining 81 of its 2024 and 2025 contractual but undelivered aircraft (27 -7s and 54 -8s) within its 2026 contractual commitments. As Boeing continues to ramp up production and works to certify the -7, the Company expects 66 -8 aircraft deliveries in 2026. The 2026 contractual detail is as follows:

**Ground Facilities and Services**

Southwest either leases or pays a usage fee for terminal passenger service facilities at each of the airports it serves, to which various leasehold improvements have been made. The Company leases the land and/or structures on a long-term basis for its aircraft maintenance centers (located at Dallas Love Field, Houston Hobby, Phoenix Sky Harbor, Chicago Midway, Hartsfield-Jackson Atlanta International Airport, Denver International Airport, and Orlando International Airport) and its main corporate headquarters building, also located near Dallas Love Field. The Company also leases a warehouse and engine repair facility in Atlanta. The Company completed construction on a new 129,000 square foot aircraft maintenance facility at Baltimore-Washington International Airport in the second quarter of 2025.

The Company owns two additional headquarters buildings, located across the street from the Company's main headquarters building, on land owned by the Company, including (i) an energy efficient, modern building, called TOPS, which houses certain operational and training functions, including the Company's 24-hour operations and (ii) the Wings Complex, consisting of a Leadership Education and Aircrew Development ("LEAD") Center (housing the Company's 26 Boeing 737 flight simulators and classroom space for Pilot training), an additional office building, and a parking garage.

The Company has commitments associated with various airport improvement projects, including construction at Houston Hobby International Airport. This project includes the construction of new facilities and the rebuilding or modernization of existing facilities. Construction on the project has begun, and the Company expects construction to be completed in 2027. In April 2023, the Company executed a ground lease agreement with Los Angeles World Airports ("LAWA") at Los Angeles International Airport (LAX) which provides the Company the right to construct a 9-gate concourse (Concourse 0) adjacent to Terminal 1. The Company expects to manage the design, development, financing, construction, and commissioning of the project, and expects to commence construction in 2028 with construction to be completed in 2032. Prior to commencement of construction, LAWA and the Company will need to agree on scope and budget and have financing in place. Additional information regarding these projects is provided in Note 4 to the Consolidated Financial Statements.

The Company performs substantially all line maintenance on its aircraft and provides ground support services at most of the airports it serves. However, the Company has arrangements with certain aircraft maintenance providers for major component inspections and repairs for its airframes and engines, which comprise the majority of the Company's annual aircraft maintenance costs.

**Item 3.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*Legal Proceedings***

On June 30, 2015, the U.S. Department of Justice ("DOJ") issued a Civil Investigative Demand ("CID") to the Company. The CID sought information and documents about the Company's capacity from January 2010 to the date of the CID, including public statements and communications with third parties about capacity. In June 2015, the Company also received a letter from the Connecticut Attorney General requesting information about capacity. The Company is cooperating fully with the DOJ CID and the state inquiry.

Further, on July 1, 2015, a complaint was filed in the United States District Court for the Southern District of New York on behalf of putative classes of consumers alleging collusion among the Company, American Airlines, Delta Air Lines, and United Airlines to limit capacity and maintain higher fares in violation of Section 1 of the Sherman Act. Since then, a number of similar class action complaints were filed in the United States District Courts for the Central District of California, the Northern District of California, the District of Columbia, the Middle District of Florida, the Southern District of Florida, the Northern District of Georgia, the Northern District of Illinois, the Southern District of Indiana, the Eastern District of Louisiana, the District of Minnesota, the District of New Jersey, the Eastern District of New York, the Southern District of New York, the Middle District of North Carolina, the District of Oklahoma, the Eastern District of Pennsylvania, the Northern District of Texas, the District of Vermont, and the Eastern District of Wisconsin. On October 13, 2015, the Judicial Panel on Multi-District Litigation centralized the cases to the United States District Court in the District of Columbia. On March 25, 2016, the plaintiffs filed a Consolidated Amended Complaint in the consolidated cases alleging that the defendants conspired to restrict capacity from 2009 to present. The plaintiffs seek to bring their claims on behalf of a class of persons who purchased tickets for domestic airline travel on the defendants' airlines from July 1, 2011 to present. They seek treble damages, injunctive relief, and attorneys' fees and expenses. On May 11, 2016, the defendants moved to dismiss the Consolidated Amended Complaint, which the Court denied on October 28, 2016. On December 20, 2017, the Company reached an agreement to settle these cases with a proposed class of all persons who purchased domestic airline transportation services from July 1, 2011, to the date of the settlement. The Company agreed to pay $15 million and to provide certain cooperation with the plaintiffs as set forth in the settlement agreement. After notice was provided to the proposed settlement class and the Court held a fairness hearing, the Court issued an order granting final approval of the settlement on May 9, 2019. On June 10, 2019, certain objectors filed notices of appeal to the United States Court of Appeals for the District of Columbia Circuit, which the Court dismissed on July 9, 2021, for lack of jurisdiction because the district court's order approving the settlements was not a final appealable order. The case is continuing as to the remaining defendants. The Company denies all allegations of wrongdoing.

On January 7, 2019, a complaint alleging a violation of the federal Uniformed Services Employment and Reemployment Rights Act ("USERRA") and seeking a certification as a class action was filed against the Company in the United States District Court for the Northern District of California. The complaint alleges that the Company violates section 4316(b) of USERRA because it does not provide paid "short-term" military leave (i.e., a military leave of 14 days or fewer) but does provide paid jury duty leave, bereavement leave, and sick leave, which the plaintiff alleges are "comparable" forms of leave under USERRA and its implementing regulations. The complaint seeks declaratory and injunctive relief, damages, liquidated damages, interest, and attorneys' fees, expert fees, and litigation costs. On February 3, 2021, the Court granted the plaintiff's motion for class certification and issued an order certifying a class comprised of current or former Employees who, during their employment with the Company at any time from October 10, 2004, through the date of judgment in this action, have taken short-term military leave and were subject to a collective-bargaining agreement, except for Employees subject to the Transport Workers Union Local 550 agreement covering meteorologists. On January 11, 2022, the Court granted the parties' stipulated request to vacate the trial date as the Department of Defense had not yet produced the class members' military pay and service records pursuant to the Company's third-party subpoena. On August 18, 2022, the Court entered an order that effectively stayed the action, except for attention to the third-party subpoena, until after the Ninth Circuit issued its opinion in the matter of Clarkson v. Alaska Airlines, Inc. and Horizon Industries, Inc., an appeal from an order by the United States District Court for the Eastern District of Washington granting summary judgment in defendants' favor on substantially the same claims at issue in this action. The Ninth Circuit issued its order in Clarkson on February 1, 2023, reversing the district court's grant of summary judgment and remanding the Clarkson case to the District Court with instructions to consider the "pay during leave" issue in the first instance. The Company has received the military pay and service records. On October 29, 2024, the Company filed a motion to decertify the class, which was then fully briefed and set for hearing. On February 13, 2025, the parties filed a notice of settlement advising the Court that they reached a settlement in principle, and the parties made a stipulated request for the Court to vacate the case schedule, including the hearing on the Company's decertification motion, and to set a deadline of June 19, 2025, for the filing of either a motion for preliminary approval of the class settlement or a status update about the timing of the remaining steps in the settlement process. The Court granted the stipulation on February 14, 2025. On June 20, 2025, the Court granted the parties' stipulated request to continue the deadline for filing a motion for preliminary approval of the class settlement and the Court reset the deadline for

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

August 21, 2025. On September 25, 2025, plaintiffs filed a motion for preliminary approval of the settlement class. The class proposed in the settlement modifies the class definition to use an end date of January 1, 2026 (rather than treating the date of judgment as the end date). The settlement includes an $18.5 million settlement fund and prospective relief that includes a differential pay benefit for up to ten days of military leave per year, which will remain in place for at least five years once initiated. On December 11, 2025, the Court granted preliminary approval of the settlement and set the final approval hearing for May 14, 2026.

On December 27, 2019, a former customer service agent at Oakland International Airport, filed a putative class action complaint in the Superior Court of California, for the County of Santa Clara, against the Company alleging the following seven claims under the California Labor Code and Business & Professions Code: (1) failure to provide meal periods; (2) failure to provide rest periods; (3) failure to pay hourly wages; (4) failure to provide accurate wage statements; (5) failure to timely pay all final wages; (6) unfair competition; and (7) civil penalties for the foregoing. Plaintiff filed a First Amended Complaint on October 15, 2021, that asserted the same causes of action and added a named plaintiff. The First Amended Complaint primarily seeks unpaid wages, interest thereon, and associated civil and statutory penalties, along with attorneys' fees and costs. On February 26, 2025, the Court granted class certification as to the first cause of action for failure to provide meal periods, denied certification on the second through fourth causes of action, and granted certification on the fifth and sixth causes of action only insofar as they are predicated on the first cause of action. The certified class consists of all of the Company's non-exempt ground employees in California who worked a shift in excess of five hours for the time period between October 24, 2014, forward. On April 17, 2025, the Company filed a summary judgment motion arguing that Plaintiffs' first cause of action, and all causes of action predicated thereon, failed as a matter of law. The motion was granted on July 25, 2025. Judgment was entered in favor of the Company on September 2, 2025, and Plaintiffs filed a notice of appeal on September 4, 2025. The Company intends to continue to vigorously defend itself in all respects.

On June 22, 2020, a derivative action for breach of fiduciary duty was filed in the United States District Court for the Northern District of Texas naming the members of the Company's Board of Directors (the "Board") as defendants and the Company as a nominal defendant (the "Derivative Action"). The plaintiff alleges unspecified damage to Company's reputation, goodwill, and standing in the community, as well as damage from exposure to civil and regulatory liability and defense costs. According to the lawsuit, these damages arise from the Company's alleged failure to comply with safety and record maintenance regulations and false statements in public filings regarding the Company's safety practices. The plaintiff alleges the Board, in the absence of good faith, exhibited reckless disregard for its duties of oversight. On October 7, 2020, the Court entered an order staying and administratively closing the Derivative Action, pending the District Court's final resolution of the Company's motion to dismiss in a parallel securities class action under Section 10(b) of the Exchange Act that was filed on February 19, 2020, or upon the occurrence of certain other conditions. While the parallel securities class action was dismissed with prejudice on October 5, 2023, the plaintiff in the Derivative Action has taken no steps to lift the stay in the case, which remains stayed. The Board and Company deny all allegations of wrongdoing made in the Derivative Action.

On August 26, 2021, a complaint alleging breach of contract and seeking certification as a class action was filed against the Company in the United States District Court for the Western District of Texas in Waco. The complaint alleges that the Company breached its Contract of Carriage and other alleged agreements in connection with its use of the allegedly defective MAX aircraft manufactured by The Boeing Company. The complaint seeks damages on behalf of putative classes of customers who provided valuable consideration, whether in money or other form (e.g., voucher, miles/points, etc.), in exchange for a ticket for air transportation with the Company, which transportation took place between August 29, 2017, and March 13, 2019. The complaint generally seeks money damages, declaratory relief, and attorneys' fees and other costs. On October 27, 2021, the Company filed a multi-faceted motion challenging the complaint based upon lack of subject matter jurisdiction, the existence of a prior-filed complaint on appeal in the Fifth Circuit (the "Sherman Complaint"), improper venue, and failure to state a claim, and seeking to have the complaint's class contentions stricken. That motion was fully briefed by both parties and was argued to a United States Magistrate Judge on June 27, 2022. On July 5, 2022, the Magistrate Judge granted the motion in part and ordered the case stayed until the issuance of the Fifth Circuit's opinion in the Sherman Complaint. On November 28, 2022, the parties jointly notified the Court of the Fifth Circuit's decision regarding the Sherman Complaint. On March 23, 2023, the parties jointly notified the Court of the dismissal of the Sherman Complaint for lack of jurisdiction. Following more recent communications by the parties regarding the status of the stay, the Court directed the parties to file a joint status report, which was filed on February 24, 2025, with the

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

Company renewing its request that the case be dismissed for lack of standing and lack of subject matter jurisdiction in light of the Fifth Circuit's decision regarding the Sherman Complaint, which the plaintiffs opposed. On March 11, 2025, the Court heard argument of the parties' respective positions on the Company's request for dismissal for lack of standing and lack of subject matter jurisdiction. On June 9, 2025, the Court issued an order dismissing the case for lack of standing and lack of subject matter jurisdiction and entered final judgment in favor of the Company. On July 9, 2025, the plaintiffs in the case filed a notice of appeal to the Fifth Circuit Court of Appeals. The appeal has now been fully briefed by the parties. No oral argument has been set. The Company continues to deny all allegations of wrongdoing, believes the plaintiffs' positions are without merit, and intends to vigorously defend itself against the appeal.

Two complaints alleging violations of federal securities laws and seeking certification as a class action were filed (on January 10, 2023, and March 13, 2023, respectively) against the Company and certain of its officers in the United States District Court for the Southern District of Texas in Houston. The complaints seek damages on behalf of a putative class of persons who purchased or otherwise acquired the Company's common stock between June 13, 2020, and December 31, 2022. The complaints assert claims under Sections 10(b) and 20 of the Exchange Act and allege that the Company made material misstatements to investors regarding the Company's internal technology and alleged vulnerability to large-scale flight disruptions. The complaints generally seek money damages, pre-judgment and post-judgment interest, and attorneys' fees and other costs. The deadline in the first of these two cases to file a motion seeking appointment of lead plaintiff was March 13, 2023; four separate motions were filed, and three of the parties seeking appointment contested the issue. On July 17, 2023, the Court signed an order consolidating the two federal securities cases into the first-filed suit and also appointed plaintiff Michael Berry as lead plaintiff in the consolidated case, with his counsel of record to serve as lead counsel and liaison counsel. On September 15, 2023, the lead plaintiff filed an amended complaint that expanded the class period to include persons who purchased or otherwise acquired the Company's common stock between February 4, 2020, and March 14, 2023, while continuing to assert claims under Sections 10(b) and 20 of the Exchange Act based on alleged misstatements regarding the Company's internal technology and alleged vulnerability to large-scale flight disruptions. On November 20, 2023, the Company and the individual defendants filed a motion to dismiss the amended complaint for failure to state a claim. Plaintiffs filed an opposition brief on January 26, 2024. The Company and the individual defendants filed a reply brief on February 23, 2024. On December 5, 2024, the United States District Court for the Southern District of Texas denied the motion to dismiss on the basis that "the issues are better suited for a summary judgment motion after the parties have had the opportunity to engage in discovery." On December 21, 2024, the Company moved for reconsideration of the December 5, 2024, order and, in the alternative, for permission to pursue an interlocutory appeal. The plaintiffs opposed both requests for relief. On April 3, 2025, the United States District Court for the Southern District of Texas conducted a hearing on the Company's motion for reconsideration and requested the parties to confer and submit an agreed post-hearing briefing schedule in order for the Court to evaluate and determine the sufficiency of the allegations in Plaintiffs' amended complaint in accordance with the Private Securities Litigation Reform Act. The parties' respective briefing on these issues has been completed and the matter remains pending for a decision by the Court. The Company denies all allegations of wrongdoing in the complaint, believes the plaintiffs' positions are without merit, and intends to vigorously defend itself in all respects.

Starting on or about January 24, 2023, the Company's senior officers and the Board received multiple derivative demand letters from legal counsel for purported Southwest Shareholders demanding that the Board investigate claims, initiate legal action, and take remedial measures in connection with the service disruptions occurring in December 2022. Generally, the demand letters broadly assert that the Company's directors and senior officers did not make sufficient investments in internal technology systems to prevent large-scale flight disruptions, did not exercise sufficient oversight over the Company's operations, approved or received unwarranted compensation, caused the Company to make materially misleading public statements, and breached their fiduciary duties to the Company. Additionally, since January 27, 2023, the Company has received multiple letters from counsel for purported Southwest Shareholders making statutory demands for the production of various books and records of the Company, purportedly in an effort to investigate possible derivative claims similar to those made the subject of the derivative demands discussed above. On June 13, 2023, a shareholder derivative suit was filed against certain of the Company's current and former officers and directors in the 14th Judicial District Court of Dallas County, Texas, asserting claims for damages from alleged breach of fiduciary duty, waste of corporate assets, and unjust enrichment derivatively on the Company's behalf against the individual defendants based on similar factual allegations as contained in the demand letters and in the federal class action complaints. On June 15, 2023, a second shareholder derivative suit was filed against certain of the Company's current and former officers and directors in the United States District Court for the Northern District of Texas, asserting claims under Section 14(a) of the Exchange Act

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

and for damages from alleged breach of fiduciary duty, indemnification, and unjust enrichment derivatively on the Company's behalf against the individual defendants based on similar factual allegations as contained in the demand letters and in the federal class action complaints. On November 14, 2023, a third shareholder derivative suit was filed in the 134th Judicial District of Dallas County, Texas, by some of the same counsel involved in the June 13, 2023, suit against the same defendants in that suit and making allegations of the same operative facts and claims. On June 18, 2024, a fourth shareholder derivative suit was filed in the 101st Judicial District Court of Dallas County, Texas, asserting substantially similar claims as in the first two state court derivative suits. On June 26, 2024, a fifth shareholder derivative suit was filed in the United States District Court for the Northern District of Texas, asserting substantially similar claims as in the first federal derivative suit. On July 18, 2024, a sixth shareholder derivative suit was filed in the United States District Court for the Northern District of Texas, asserting substantially similar claims as in the first federal derivative suit (together with the previous demand letters and shareholder derivative suits, the "Derivative Actions and Demands").

The Company and the Board have addressed the Derivative Actions and Demands in accordance with the applicable Texas statutes governing such demands and litigation. Pursuant to those statutes, a committee of independent and disinterested directors (the "Special Litigation Committee") was appointed to conduct an inquiry regarding the allegations in the Derivative Actions and Demands. The state court cases have been consolidated into one state court case, and the federal cases were later consolidated into one federal case.

As described above, pursuant to the applicable Texas statutes governing derivative demands and litigation, the Special Litigation Committee was duly appointed to conduct an inquiry regarding the claims and allegations asserted in the Derivative Actions and Demands. The Derivative Actions and Demands were all stayed, formally or by agreement, pending the outcome of the investigation by the Special Litigation Committee. On September 19, 2024, the Special Litigation Committee formally reported its findings and resolution concerning its investigation of the Derivative Actions and Demands, which began in July 2023 and concluded with the September 19, 2024 report and resolution, which in turn were delivered to the Company and its Board on September 23, 2024. The Special Litigation Committee retained two law firms to represent the Special Litigation Committee in connection with the Special Litigation Committee's investigation of the Derivative Actions and Demands and the Special Litigation Committee's review and assessment of evidence gathered in its investigation. The Special Litigation Committee further reported, among other details, upon its appointment, the independence and disinterestedness of its members, the Special Litigation Committee's investigative processes, including meetings, scope of investigation, volume of documents reviewed, numbers of witnesses interviewed, other presentations received, review and analysis of evidence and applicable legal standards, work with its counsel, and findings and preparation of the final report and resolution of the Special Litigation Committee. Based upon the Special Litigation Committee report and the conclusions reached therein, the Special Litigation Committee, consistent with its appointment and delegated authority, unanimously adopted a resolution (i) determining that it is not in the best interests of the Company or its Shareholders to pursue the relief requested in the Derivative Actions and Demands; (ii) determining that it is in the best interests of the Company and its Shareholders to reject the Derivative Actions and Demands; (iii) determining that it is in the best interests of the Company and its Shareholders for the Company to move to dismiss the Derivative Actions and Demands; and (iv) instructing that the Company and counsel take all further actions necessary to implement the resolution. On December 26, 2024, the Board received a seventh demand letter, and on January 31, 2025, received an eighth demand letter, each containing allegations substantially similar to those presented in certain of the prior Derivative Actions and Demands, which are being addressed consistent with applicable Texas law governing such demands. On April 1, 2025, the Company filed a motion to dismiss or stay the consolidated state court derivative actions based on the forum selection clause in the Company's bylaws and the pendency of the related federal derivative cases. In May 2025, the Company and the plaintiffs in the state court derivative actions filed a joint stipulation and proposed order to stay the state court derivative actions and, among other things, to make a ruling on a motion to dismiss in the federal derivative case binding upon the state court derivative actions. On June 18, 2025, the Company filed a motion to lift the stay in the consolidated federal derivative actions and an accompanying motion to dismiss based on the Special Litigation Committee's report, conclusions, and resolution. The parties have submitted to the Court a stipulation with a proposed schedule pertaining to further briefing and related proceedings in connection with the motion to dismiss. The stipulation has not yet been signed by the Court.

Based on the Company's wide-scale operational disruption, which led to the cancelation of a significant number of flights between December 21 and December 29, 2022, the Company has been subject to inquiries and investigations by governmental agencies (including with respect to a December 2023 settlement with the DOT) and could be

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

subject to fines and/or penalties resulting from those inquiries and investigations, as well as litigation from Customers and Shareholders.

On January 28, 2025, two participants in the Company's retirement plans commenced a putative class action in the United States District Court for the Northern District of Texas against the Company, the Board, and certain of the Company's officers. Plaintiffs purport to represent a class consisting of participants and beneficiaries in the Southwest Airlines Co. Retirement Savings Plan, the Southwest Airlines Co. 401(k) Plan, and the Southwest Airlines Co. ProfitSharing Plan (collectively, the "Plan") who invested in the Harbor Capital Appreciation Fund from January 28, 2019 "through the date of judgment." The complaint asserts that defendants mismanaged Plan assets and failed to monitor the Plan in violation of the Employee Retirement Income Security Act by, among other things, failing to remove the Harbor Fund as an investment option. The complaint seeks various forms of declaratory and monetary relief as well as attorneys' fees, interest and other costs. The defendants deny all allegations of wrongdoing, believe the plaintiffs' claims are without merit, and intend to vigorously defend against these claims.

On April 29, 2025, the Company received a demand letter addressed to the Board, dated April 28, 2025, from a purported Southwest Shareholder contending that the Company's directors and senior officers breached their fiduciary duties in connection with the Board's decision to end Southwest's Bags Fly Free policy and to begin charging passengers for bags. The letter demanded that the Board investigate the circumstances surrounding the policy change and bring suit against individual directors and officers who allegedly breached their duties to the Company. On June 27, 2025, the Company sent a response to the demand letter on behalf of the Board rejecting the allegations and denying them and any other form of wrongdoing. The response letter also noted that the Board approved an amendment and restatement of the Company's bylaws that, among other things, established a minimum ownership threshold of three percent of Southwest's outstanding shares in order for a Southwest shareholder to institute or maintain a derivative proceeding, consistent with the provisions in Texas Senate Bill 29, which was signed into law on May 14, 2025. The response letter further noted that the purported shareholder who sent the demand letter claims to hold only 100 shares of the Company's stock and thus fell well short of the three percent threshold. On July 10, 2025, the shareholder who sent the demand filed a shareholder derivative complaint in the United States District Court for the Northern District of Texas against various directors and officers of the Company based on the contentions asserted in the demand letter. The suit asserts, among other things, that the decision to change Southwest's Bags Fly Free policy conflicts with the Company's prior views regarding the policy and is detrimental to the Company's business, and that the Company's directors approved the policy to accede to pressure from large shareholder Elliott Investment Management L.P., to preserve their Board seats, or both, rather than to serve the Company's interests. The complaint also asserts that the amendment and restatement of the Company's bylaws is ineffective. On August 25, 2025, the Company and its Board moved to dismiss the derivative complaint and all claims on the grounds, among others, that the suit is barred by Texas Senate Bill 29 and the Company's bylaw passed pursuant thereto requiring a three percent ownership threshold in order for Company shareholders to bring derivative claims. The plaintiff opposed the motion, claiming the purportedly retroactive application of Texas Senate Bill 29 and the Company bylaw are unconstitutional; and the Company filed a reply in support of its motion to dismiss. Additionally, multiple entities sought and were granted leave to file three separate amicus curiae briefs in support of the Company's motion to dismiss and Texas Senate Bill 29; those included one amicus brief each by: (i) the Chamber of Commerce of the United States of America and the Texas Association of Business, (ii) the Alliance for Corporate Excellence, and (iii) Texans for Lawsuit Reform. Finally, in light of the constitutional challenge to Texas Senate Bill 29, on October 3, 2025, the State of Texas, represented by the Office of the Attorney General of Texas, filed a motion to intervene in the case and its own accompanying motion to dismiss the plaintiff's derivative suit and all claims therein as barred by Texas Senate Bill 29. The State of Texas's motion to intervene was granted, and its motion to dismiss has been fully briefed by both the State and the plaintiff. The motions to dismiss of both the Company and the State of Texas remain pending and awaiting decision by the Court. The Company and its Board deny all allegations of wrongdoing, believe the plaintiffs' positions are without merit, and intend to vigorously defend themselves in all respects.

The Company is from time to time subject to various legal proceedings and claims arising in the ordinary course of business, including, but not limited to, examinations by the Internal Revenue Service and state and local income tax authorities.

The Company's management does not expect that the outcome in any of its currently ongoing legal proceedings or the outcome of any proposed adjustments presented to date by the Internal Revenue Service and state and local

(1) On September 25, 2024, the Board authorized the repurchase of up to $2.5 billion of the Company's common stock, of which no amounts remained as of the end of second quarter 2025. On July 23, 2025, the Board approved a $2.0 billion share repurchase authorization of the Company's common stock. Subject to certain conditions, repurchases may be made in accordance with applicable securities laws in open market or private, including accelerated, repurchase transactions from time to time, depending on market conditions.

(2) Excludes immaterial amount of excise tax on share repurchases, net of issuances.

(3) Under an accelerated share repurchase program entered into by the Company with a third-party financial institution in third quarter 2025 (the "Third Quarter 2025 ASR Program"), the Company paid $250 million and received an initial delivery of 6,368,213 shares during September 2025, representing an estimated 80 percent of the shares to be purchased by the Company under the Third Quarter 2025 ASR Program. This share amount was based on the $31.39 and $31.43 closing price of the Company's common stock on September 5, 2025 and September 15, 2025, respectively. Upon settlement, the third-party financial institution delivered 1,409,551 additional shares of the Company's common stock to the Company in October 2025 based on a discount to the volume-weighted average price per share of the Company's common stock during the calculation period. Upon completion of the Third Quarter 2025 ASR Program in October 2025, the average purchase price per share for the 7,777,764 shares repurchased was $32.14.

(4) Under an accelerated share repurchase program entered into by the Company with a third party financial institution in fourth quarter 2025 (the "Fourth Quarter 2025 ASR Program"), the Company paid $50 million and received an initial delivery of 1,224,740 shares during November 2025, representing an estimated 80 percent of the shares to be purchased by the Company under the Fourth Quarter 2025 ASR Program. This share amount was based on the $32.66 closing price of the Company's common stock on November 10, 2025. Final settlement of the Fourth Quarter 2025 ASR Program occurred in December 2025 and was based on a discount to the volume-weighted average price per share of the Company's common stock during a calculation period completed in December 2025. Upon settlement, the third party financial institution delivered 106,178 additional shares of the Company's common stock to the Company. Upon completion of the Fourth Quarter 2025 ASR Program in December 2025, the average purchase price per share for the 1,330,918 shares repurchased was $37.57.

(5) In addition, under a forward contract entered into by the Company in December 2025, the Company committed $750 million for an accelerated share repurchase program with a third party financial institution (the "January 2026 ASR Program") under which the Company paid $750 million in January 2026 and received total delivery of 17,965,193 shares as settlement in full. Upon completion of the January 2026 ASR Program in January 2026, the average purchase price per share of the 17,965,193 shares repurchased was $41.75. The $750 million paid in January correspondingly reduced the maximum dollar value of shares that may yet be purchased under the repurchase program to $950 million.

(6) Under an accelerated share repurchase program entered into by the Company with a third party financial institution in January 2026 (the "First Quarter 2026 ASR Program"), the Company paid $400 million and received an initial delivery of 6,597,939 shares during January 2026, representing an estimated 80 percent of the shares to be purchased by the Company under the First Quarter 2026 ASR Program. This share amount was based on the $48.50 closing price of the Company's

------

common stock on January 29, 2026. Final settlement of the First Quarter 2026 ASR program is scheduled to occur by the end of April 2026 and will be based on a discount to the volume-weighted average price per share of the Company's common stock during a calculation period to be completed at time of settlement. The $400 million paid in first quarter 2026 correspondingly reduced the maximum dollar value of shares that may yet be purchased under the repurchase program to $550 million.

**Item 7**.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***Management's Discussion and Analysis of Financial Condition and Results of Operations***

**YEAR IN REVIEW**

The Company had a record full year revenue performance in 2025, producing operating revenues of $28.1 billion, due in part to continued strong domestic travel demand, as well as the execution of transformational initiatives, which has resulted in strong financial performance and driven incremental Shareholder value.

The Company recorded results for 2025 and 2024, on an accounting principles generally accepted in the United States ("GAAP") and non-GAAP basis, as noted in the following tables. See Note Regarding Use of Non-GAAP Financial Measures and the Reconciliation of Reported Amounts to Non-GAAP Financial Measures for additional detail regarding non-GAAP financial measures.

---

The Company's operating income, as shown above on a GAAP and non-GAAP basis for the year ended December 31, 2025, increased compared to the same prior year period primarily driven by revenue initiatives, including the Company's policy change related to certain Customers' first and second checked bags that became effective May 28, 2025. This increase was combined with outperformance of cost reduction goals and lower year-over-year Fuel and oil expense primarily driven by lower jet fuel prices, partially offset by higher salaries, wages, and benefits expense. Despite the negative impacts to bookings and travel associated with the government shutdown during a portion of fourth quarter 2025, the Company earned an outsized portion of its 2025 operating income during the period. On a GAAP basis, the Company achieved in excess of 90 percent, and on a non-GAAP basis, achieved in excess of 70 percent, of its annual operating income during the fourth quarter of the year, both primarily as a result of the ramp-up of its transformational and revenue initiatives over the course of the year. The Company's net income, as shown above on a GAAP and non-GAAP basis for the year ended December 31, 2025, decreased compared to the same prior year period primarily due to a decrease in interest income driven by a lower cash and investment balance. Additionally, on a GAAP basis, the Company's results for the year ended December 31, 2024, included a reversal of $116 million of breakage revenue recorded in prior years related to a portion of flight credits issued to Customers during 2022 and prior that either were redeemed or are expected to be redeemed in future periods. The majority of these flight credits were issued during the COVID-19 pandemic as the Company was making significant changes to its flight schedules based on fluctuating demand. This adjustment was treated as a special item and excluded from the Company's presentation of non-GAAP results. See Note Regarding Use of Non-GAAP Financial Measures and the Reconciliation of Reported Amounts to Non-GAAP Financial Measures for additional detail regarding non-GAAP financial measures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Updated its flight credit policy for tickets purchased on or after May 28, 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Began selling assigned and extra legroom seating for travel beginning January 27, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expanded distribution channels through new partnerships with online travel agencies, Expedia and Priceline;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Better optimized its Rapid Rewards<sup>®</sup> program, including variable earn and burn rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amended its co-brand credit card agreement with JPMorgan Chase Bank, N.A. ("Chase"), including new benefits and improved economics;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Launched Getaways by Southwest™, an in-house packaged vacations product;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced free Wi-Fi sponsored by T-Mobile for all Rapid Rewards Members beginning October 24, 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Added redeye flying to increase aircraft utilization and network connectivity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reduced turn time to increase aircraft utilization;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Deployed new technology boosting operational reliability, a key enabler of the Company's #1 rank in The Wall Street Journal Best U.S. Airlines of 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Launched a partnership with Hahnair to expand its global ticketing reach; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced six strategic partnerships with Icelandair, EVA Air, China Airlines, Philippine Airlines, Condor, and Turkish Airlines.

In January 2026, the Company began operating assigned and extra legroom seating for travel beginning on January 27, 2026, which required retrofitting 780 aircraft. With assigned and extra legroom seating becoming operational, Southwest expects future earnings upside based on how booking behavior related to these initiatives unfolds. This includes upsell revenue from close-in bookings, which are more closely affiliated with business and price-flexible Customers, as well as growth in business and leisure Customer segments driven by the more attractive new product offering.

The Company has also continued to enhance its onboard offerings, with improvements such as faster WiFi, in-seat power, and larger overhead bins, and work is well underway on a refreshed cabin design, including new, more comfortable RECARO seats. The first Boeing 737-8 ("-8") aircraft with an updated cabin was delivered and entered service on October 16, 2025.

*Other Initiatives and Developments*

The Company has also announced its intention to commence new service at multiple locations in an effort to grow its network and provide more destinations for Customers. These locations include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cyril E. King International Airport on St. Thomas beginning early 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• McGhee Tyson Airport in Knoxville, Tennessee beginning March 5, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Princess Juliana International Airport on St. Maarten beginning April 7, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Charles M. Schulz Sonoma County Airport in Santa Rosa, California beginning April 7, 2026; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ted Stevens Anchorage International Airport in Anchorage, Alaska beginning in the first half of 2026.

During 2025, the Company continued to deliver value to its Shareholders by returning $2.9 billion to Shareholders through $399 million in dividend payments and $2.6 billion through accelerated share repurchase programs entered into by the Company with third party financial institutions. In addition, under a forward contract entered into by the Company in December 2025, the Company committed $750 million for an accelerated share repurchase program with a third party financial institution (the "January 2026 ASR Program") under which the Company paid $750 million in January 2026 and received total delivery of 17,965,193 shares to the Company as settlement in full. Additionally, the Company launched a $400 million accelerated share repurchase program in January 2026 (the "First Quarter 2026 ASR Program") that is scheduled to be completed by the end of April 2026. All of the Company's share repurchases will be recorded as treasury share repurchases for purposes of calculating earnings per share. Upon completion of the Company's January 2026 share repurchase activity, the Company will have $550 million remaining under its July 2025 $2.0 billion share repurchase authorization. See Part II, Item 5 for further information on the Company's share repurchase authorizations.

In December 2025, the U.S. Department of Transportation ("DOT") amended a December 2023 order assessing a civil penalty of $140 million on the Company resulting from its December 2022 operational disruption by waiving the final cash installment that was due January 31, 2026, and issuing the Company an $11 million credit for the Company significantly improving its ontime performance and completion factor.

In February 2025, the Company implemented a reduction in workforce that provided for the reduction of approximately 1,750 Employee roles, or 15 percent of corporate positions. As a result of the reduction in workforce, the Company incurred a one-time expense of $62 million during first quarter 2025, achieved 2025 savings of approximately $230 million, and estimates 2026 savings of approximately $310 million. Separations were substantially complete by the end of second quarter 2025. See Note 16 to the Consolidated Financial Statements for further information.

*Fleet Information*

As a result of The Boeing Company's ("Boeing") delivery delays, the Company has previously replanned its capacity and delivery expectations multiple times and will continue to closely monitor the ongoing aircraft delivery delays with Boeing and further adjust expectations as needed.

The Company ended 2025 with 803 Boeing 737 aircraft, including 300 -8 aircraft. During 2025, the Company retired 55 aircraft (including 48 Boeing 737-700 ("-700") aircraft, and seven Boeing 737-800 ("-800") aircraft, inlcuding the sale of five -800 aircraft) and took delivery of 55 -8 aircraft. The Company also completed the sale-leaseback of one -800 aircraft in January 2025. The Company's order book with Boeing as of January 29, 2026, consists of a total of 467 MAX firm orders (271 Boeing 737-7 ("-7") aircraft and 196 -8 aircraft) for the years 2026 through 2031, including 27 -7 aircraft that were contractually committed for 2024, and 54 -8s that were contractually committed for 2025, but were not received, and 150 MAX options (-7s or -8s) for the years 2027 through 2031. The Company expects 66 -8 aircraft deliveries in 2026, which differs from its contractual order book, as Boeing continues to ramp up production and works to certify the -7. This expectation supports the Company's plans to retire approximately 60 aircraft in 2026. The Company's aircraft delivery and retirement expectations for 2026 and beyond are fluid and subject to Boeing's production capability.

As of February 5, 2026, the Company has published its flight schedule through September 30, 2026.

**Operating Revenues**

Passenger revenues for 2025 increased by $555 million, or 2.2 percent, compared with 2024, to achieve an all-time full year Company record of $25.5 billion. On a unit basis, Passenger revenues increased 0.6 percent, year-over-year. On both a dollar basis and a per unit basis, the increase was primarily due to an increase in bag fee revenues driven by the Company's policy change, coupled with an increase in the portion of the Company's co-brand credit card benefits that are now classified within Passenger revenues as a result of the amended and restated co-brand agreement with Chase.

Other revenues for 2025 increased by $29 million, or 1.2 percent, compared with 2024. On both a dollar basis and a per unit basis, the increase was primarily due to a $30 million increase in loyalty revenues due to a higher portion of revenues recognized sooner associated with the Company's co-brand agreement with Chase, as a result of the contract amendments with Chase in 2025. See Note 5 to the Consolidated Financial Statements for further information.

**Operating Expenses**

Operating expenses for 2025 increased by $473 million, or 1.7 percent, compared with 2024, and capacity increased 1.6 percent over the same prior year period. A majority of the operating expenses increase was due to higher Salaries, wages, and benefits expense, partially offset by outperforming cost reduction goals, including the Company's first quarter 2025 workforce reduction, and lower Fuel and oil expense. The following table presents the Company's Operating expenses per ASM for 2025 and 2024, followed by explanations of these changes on a dollar basis.

Operating expenses per ASM for 2025 increased by 0.2 percent, compared with 2024, primarily driven by higher Salaries, wages, and benefits expense, offset by the decrease in the Company's fuel cost per gallon. Operating expenses per ASM for 2025, excluding Fuel and oil expense, profitsharing, and special items (a non-GAAP financial measure), increased 3.1 percent, year-over-year. See Note Regarding Use of Non-GAAP Financial Measures and the Reconciliation of Reported Amounts to Non-GAAP Financial Measures for additional detail regarding non-GAAP financial measures.

Salaries, wages, and benefits expense for 2025 increased by $723 million, or 5.9 percent, compared with 2024. On a per ASM basis, Salaries, wages, and benefits expense for 2025 increased 4.3 percent, compared with 2024. On a dollar and per ASM basis, the majority of the increase was due to net step/pay rate increases and related benefits for the Company's workforce.

On May 16, 2025, the Company's 35 Network Operations Control Customer Planners, added to the existing Passenger Service Employees craft or class to be represented by the International Association of Machinists and Aerospace Workers ("IAM"), entered into a tentative agreement as part of the accretion process to join an existing collective-bargaining agreement. The vote to ratify a contract amendment with the Company failed, and the Company is continuing negotiations with the IAM.

On September 3, 2025, the Company and Transport Workers of America Union Local 557 ("TWU 557"), representing the Company's approximately 216 Flight Instructors, reached a tentative agreement on a three year extension of their collective-bargaining agreement from 2027 to 2030. The vote to ratify the extension with the Company failed, and the Company and TWU 557 are preparing to open full negotiations in 2026.

Fuel and oil expense for 2025 decreased by $572 million, or 9.8 percent, compared with 2024. On a per ASM basis, Fuel and oil expense for 2025 decreased 11.0 percent. On a dollar and per ASM basis, the decrease was primarily attributable to a decrease in fuel prices. The Company's 2025 average economic fuel cost was $2.41 per gallon with no cash settlements from hedging activities compared with an average economic fuel cost of $2.66 per gallon, which was net of approximately $53 million in cash settlements from hedging activities, in 2024. During second quarter 2025, the Company terminated its remaining portfolio of fuel hedging contracts, which were scheduled to settle through 2027, to effectively close its fuel hedging portfolio and program. However, this termination had no impact on the Company's Fuel and oil expense, as all hedge positions were out of the money and just consisted of remaining time value. The following table provides more information on the Company's economic fuel cost per gallon, including the impact of fuel hedging premium expense and fuel derivative contracts:

(a) Includes amounts reclassified from Accumulated Other Comprehensive Income associated with hedges previously terminated. See Note 10 to the Consolidated Financial Statements for further information.

See Note Regarding Use of Non-GAAP Financial Measures and the Reconciliation of Reported Amounts to Non-GAAP Financial Measures for additional detail regarding non-GAAP financial measures.

The Company's 2025 available seat miles per gallon ("fuel efficiency") improved 2.7 percent, year-over-year, due to operating more -8 aircraft, the Company's most fuel-efficient aircraft, as a percentage of its fleet. The continued deliveries of MAX aircraft are expected to remain critical to the Company's efforts to modernize its fleet.

As a result of applying hedge accounting in prior periods, the Company has amounts in Accumulated other comprehensive income ("AOCI") that will be recognized in the Consolidated Statement of Comprehensive Income in the periods the originally forecasted transactions occur, including deferred losses of $115 million in 2026 and $22 million in 2027 as of December 31, 2025 (net of tax). See Note 12 to the Consolidated Financial Statements for additional information on AOCI.

Maintenance materials and repairs expense for 2025 decreased by $126 million, or 9.3 percent, compared with 2024. On a per ASM basis, Maintenance materials and repairs expense decreased 10.5 percent, compared with 2024. On a dollar and per ASM basis, approximately 70 percent of the decrease was driven by fewer airframes in routine heavy check compared to 2024 as a result of the early retirement of a portion of the -700 fleet, and approximately 20 percent of the decrease was due to less routine bulk purchases of materials for the Company's seat refurbishment efforts.

Landing fees and airport rentals expense for 2025 increased by $216 million, or 11.0 percent, compared with 2024. On a per ASM basis, Landing fees and airport rentals expense increased 9.0 percent, compared with 2024. On a dollar and per ASM basis, approximately 50 percent of the increase was primarily attributable to an increase in airport rental expense throughout the network driven by higher rates charged by airports for leased space, 30 percent of the increase was primarily due to higher landing fees throughout the network, primarily driven by increased usage of the heavier -8 aircraft and higher rates, and 20 percent of the increase was due to receiving fewer favorable settlements and credits from various airports in 2025.

Depreciation and amortization expense for 2025 decreased by $97 million, or 5.9 percent, compared with 2024. On a per ASM basis, Depreciation and amortization expense decreased by 6.5 percent, compared with 2024. On a dollar and per ASM basis, this decrease was primarily due to a $109 million decrease from accelerating depreciation of fewer -700 aircraft planned for early retirement in 2025 compared to 2024, a $41 million decrease due to the fleet transactions completed during the December 2024 and January 2025 timeframe, and a $37 million decrease due to a change in estimate for the residual values of the Company's -700 airframes and -700, -800, and -8 engines. These decreases were partially offset by a $47 million increase from new technology assets being placed into service and a $41 million increase from the acquisition of 55 -8 aircraft during 2025.

Other operating expenses for 2025 increased by $329 million, or 8.0 percent, compared with 2024. Included within this line item was aircraft rentals expense in the amount of $322 million and $220 million for 2025 and 2024, respectively. On a per ASM basis, Other operating expenses increased 5.6 percent, compared with 2024. On a dollar and per ASM basis, the increase was due to (i) a $102 million increase in aircraft rental expense associated with fleet transactions completed during the December 2024 and January 2025 timeframe, (ii) a $92 million gain on the sale-leaseback of 35 -800 aircraft in 2024, (iii) a $77 million increase in Employee related expenses driven by higher travel expenses due to inflation in lodging rates and utilization of rooms as a result of redeye flying in 2025, and (iv) a $64 million increase in third party software maintenance agreement expense driven by expanded cloud-based services. See Note 7 to the Consolidated Financial Statements for further information on the sale-leaseback transaction.

**Non-Operating Expenses (Income)**

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

Interest expense for 2025 decreased by $82 million, or 32.9 percent, compared with 2024, primarily due to the Company's significant debt repayments in late 2024 and throughout 2025. These decreases were partially offset by the issuance of the 5.25% unsecured notes and 4.375% unsecured notes in November 2025. See Note 6 to the Consolidated Financial Statements for further information.

Capitalized interest for 2025 increased by $19 million, or 54.3 percent, compared with 2024, primarily due to an increase in various technology projects, facilities projects, and aircraft under construction.

Interest income for 2025 decreased by $292 million, or 58.8 percent compared with 2024, primarily due to lower cash and investment balances and a lower interest rate in the Company's total investment portfolio.

Other (gains) losses, net, primarily includes amounts recorded as a result of the Company's deferred compensation and hedging activities. See Note 10 to the Consolidated Financial Statements for further information on the Company's hedging activities.

**Income Taxes**

The Company's annual 2025 effective tax rate was 21.7 percent, compared with 22.2 percent in 2024. The year-over-year decrease in the tax rate is primarily due to lower state deferred tax rates in 2025 and a decrease in non-deductible expenses. The tax rate decrease was partially offset by a reduction in federal tax credits generated in 2025.

***2024 Compared with 2023***

The Company's comparison of 2024 results to 2023 results is included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2024, under Part II Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations.

(a) Includes amounts reclassified from Accumulated Other Comprehensive Income associated with hedges previously terminated. See Note 10 to the Consolidated Financial Statements for further information.

(b) See Note 10 to the Consolidated Financial Statements for further information.

(c) Represents Employee severance payments and related professional fees resulting from the workforce reduction in February 2025 ($53 million in Salaries, wages, and benefits and $9 million in Other operating expenses). See Note 16 to the Consolidated Financial Statements for further information.

(d) Represents a change in breakage revenue estimate related to flight credits the Company issued to Passengers during 2022 and prior. On July 28, 2022, the Company modified its policy and announced that all unexpired flight credits as of that date, including a significant volume of such credits issued to impacted Customers during the COVID-19 pandemic as the Company was making significant changes to its schedules based on fluctuating demand, will no longer have an expiration date and thus will be able to be redeemed by Customers indefinitely. This change in policy was considered a contract modification under ASC 606, Revenue from Contracts with Customers, and the Company accounted for such change prospectively in third quarter 2022. At that time, based on historical Customer behavior, the Company estimated that redemptions of these flight credits would have been reduced to an immaterial amount during 2024 and recognized breakage revenue in prior periods for these flight credits accordingly; however, based on actual Customer redemptions throughout 2024, as well as projected redemptions beyond 2024, the Company determined a reversal of a portion of this prior breakage revenue was warranted in 2024. This adjustment is not reflective of base business revenue trends in fourth quarter 2024 or beyond. See the Note Regarding Use of Non-GAAP Financial Measures for further information.

(e) Tax amounts for each individual special item are calculated at the Company's effective rate for the applicable period and totaled in this line item.

**Note Regarding Use of Non-GAAP Financial Measures** 

The Company's Consolidated Financial Statements are prepared in accordance with GAAP. These GAAP financial statements may include (i) unrealized noncash adjustments and reclassifications, which can be significant, as a result of accounting requirements and elections made under accounting pronouncements relating to derivative instruments and hedging and (ii) other charges and benefits the Company believes are unusual and/or infrequent in nature and thus may make comparisons to its prior or future performance difficult. &nbsp;&nbsp;&nbsp;&nbsp;

As a result, the Company also provides financial information in this filing that was not prepared in accordance with GAAP and should not be considered as an alternative to the information prepared in accordance with GAAP. The Company provides supplemental non-GAAP financial information (also referred to as "excluding special items"), including results that it refers to as "economic," which the Company's management utilizes to evaluate its ongoing financial performance and the Company believes provides additional insight to investors as supplemental information to its GAAP results. The non-GAAP measures provided that relate to the Company's performance on an economic fuel cost basis include Fuel and oil expense, non-GAAP; Total operating expenses, non-GAAP; Operating expenses, non-GAAP excluding Fuel and oil expense; Operating expenses, non-GAAP excluding Fuel and oil expense and profit sharing; Operating income, non-GAAP; Other gains, net, non-GAAP; Income before income taxes, non-GAAP; Provision for income taxes, net, non-GAAP; Net income, non-GAAP; Net income per share, diluted, non-GAAP; and Operating expenses per ASM, non-GAAP, excluding Fuel and oil expense and profit sharing (cents). For periods in which fuel hedge contracts are utilized, the Company's economic Fuel and oil expense results may differ from GAAP results in that they only include the actual cash settlements from fuel hedge contracts - all reflected within Fuel and oil expense in the period of settlement. Thus, Fuel and oil expense on an economic basis has historically been utilized by the Company, as well as some of the other airlines that utilize fuel hedging, as it reflects the Company's actual net cash outlays for fuel during the applicable period, inclusive of settled fuel derivative contracts. Any net premium costs paid related to option contracts that are designated as hedges are reflected as a component of Fuel and oil expense, for both GAAP and non-GAAP (including economic) purposes in the period of contract settlement. The Company believes these economic results provide further insight into the impact of the Company's fuel hedges on its operating performance and liquidity since they exclude the unrealized, noncash adjustments and reclassifications that are recorded in GAAP results in accordance with accounting guidance relating to derivative instruments, and they reflect all cash settlements related to fuel derivative contracts within Fuel and oil expense. This enables the Company's management, as well as investors and analysts, to consistently assess the Company's operating performance on a year-over-year or quarter-over-quarter basis after considering all efforts in place to manage fuel expense. However, because these measures are not determined in accordance with GAAP, such measures are susceptible to varying calculations, and not all companies calculate the measures in the same manner. As a result, the aforementioned measures, as presented, may not be directly comparable to similarly titled measures presented by other companies.

Further information on (i) the Company's fuel hedging program, (ii) the requirements of accounting for derivative instruments, (iii) the causes of hedge ineffectiveness and/or mark-to-market gains or losses from derivative instruments, and (iv) the Company's termination of its remaining fuel hedge derivative instruments is included in Note 10 to the Consolidated Financial Statements.

The Company's GAAP results in the applicable periods may include other charges or benefits that are also deemed "special items," that the Company believes make its results difficult to compare to prior periods, anticipated future periods, or industry trends. Financial measures identified as non-GAAP (or as excluding special items) have been adjusted to exclude special items. For the periods presented, in addition to the items discussed above, special items include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Reversal of breakage revenue previously recorded related to a portion of flight credits issued to Customers during 2022 and prior that have either been redeemed or are expected to be redeemed in future periods. The majority of these flight credits were issued during the COVID-19 pandemic as the Company was making significant changes to its flight schedules based on fluctuating demand, which made it difficult to estimate future redemption patterns when compared against historical Customer behavior;

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Incremental expense associated with a voluntary separation program that allowed eligible Employees the opportunity to voluntarily separate from the Company in exchange for severance, medical/dental coverage for a specified period of time, and travel privileges based on years of service;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.Incremental expense associated with contract ratification bonuses for various workgroups related to additional compensation for services performed by Employees outside the applicable fiscal period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.A credit received from the DOT regarding a settlement reached for the Company's December 2022 operational disruption in light of the Company significantly improving its on-time performance and completion factor through the Company's investment in its Network Operations Control;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.Expenses and/or reimbursements for incremental professional advisory fees related to activist investor activities, which were not budgeted by the Company, are not associated with the ongoing operation of the airline, and are difficult to predict in future periods;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.Charges associated with tentative litigation settlements regarding paid short-term military leave to certain Employees and an arbitration award in favor of the Company's Pilots relating to a collective-bargaining matter;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.Expenses associated with professional advisory fees related to the Company's implementation of its comprehensive transformational plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.Charges associated with severance, post-employment benefits, and professional fees as a result of the Company's reduction in workforce;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.Non-cash impairment charges to remove certain assets from the Consolidated Balance Sheet that are no longer in use;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.Expenses associated with a contract termination charge related to one of the Company's health insurance providers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.Unrealized mark-to-market adjustment associated with a forward contract entered into in fourth quarter 2025.

Because management believes special items can distort the trends associated with the Company's ongoing performance as an airline, the Company believes that evaluation of its financial performance can be enhanced by a supplemental presentation of results that exclude the impact of special items in order to enhance consistency and comparativeness with results in prior periods that do not include such items and as a basis for evaluating operating results in future periods. The following measures are often provided, excluding special items, and utilized by the Company's management, analysts, and investors to enhance comparability of year-over-year results, as well as to industry trends: Fuel and oil expense, non-GAAP; Total operating expenses, non-GAAP; Operating expenses, non-GAAP excluding Fuel and oil expense; Operating expenses, non-GAAP excluding Fuel and oil expense and profit sharing; Operating income, non-GAAP; Other gains, net, non-GAAP; Income before income taxes, non-GAAP; Provision for income taxes, net, non-GAAP; Net income, non-GAAP; Net income per share, diluted, non-GAAP; and Operating expenses per ASM, non-GAAP, excluding Fuel and oil expense and profit sharing (cents).

The Company has also provided its target for leverage, which is a non-GAAP measure of financial performance. Management believes this supplemental measure can provide a more accurate view of the Company's leverage and risk, since it considers the Company's debt and debt-like obligation profile and capital. Leverage ratios are widely used by investors, analysts, and rating agencies in the valuation, comparison, rating, and investment recommendations of companies. Although leverage ratios are commonly-used financial measures, definitions differ. The Company calculates leverage as adjusted debt divided by trailing twelve month adjusted EBITDAR. Adjusted EBITDAR is calculated as earnings before interest and taxes, and non-operating other (gains) losses, net, excluding special items, and adjusted by adding depreciation and amortization and the fixed portion of operating lease expense ("adjusted EBITDAR"). Adjusted debt includes current and long-term debt, finance lease obligations, and operating lease liabilities (including fleet, ground, and other). Projections do not reflect the potential impact of fuel and oil expense, special items, and profit sharing because the Company cannot reliably predict or estimate those items or expenses or their impact to its financial statements in future periods, especially considering the significant volatility of the fuel and oil expense line item. Accordingly, the Company believes a reconciliation of non-GAAP financial measures to the equivalent GAAP financial measures for these projected results is not meaningful or available without unreasonable effort.

**Liquidity and Capital Resources** 

Net cash provided by operating activities for 2025 was $1.8 billion, and net cash provided by operating activities for 2024 was $462 million. Operating cash inflows are historically primarily derived from selling tickets and providing air transportation to Customers. The vast majority of tickets are purchased prior to the day on which travel is provided and, in some cases, several months before the anticipated travel date. Operating cash outflows are related to the recurring expenses of airline operations. The operating cash flows for 2025 were largely impacted by the Company's net results (as adjusted for noncash items), a $103 million profit-sharing contribution for 2024 pursuant to the Company's Retirement Savings Plan, and a $1.1 billion decrease in Air traffic liability primarily driven by immediate recognition of a larger portion of revenues (and thus lower revenue deferred) associated with the Company's co-brand agreement with Chase from 2025 modifications to the agreement. See Note 5 to the Consolidated Financial Statements for further information. Operating cash flows for 2024 were largely impacted by the Company's net results (as adjusted for noncash items, primarily Depreciation and amortization and the gain on the sale-leaseback transaction), the approximately $1.9 billion paid to Pilots, Flight Attendants, and Ramp, Operations, Provisioning, and Cargo Agents as bonuses upon the ratification of the labor contract agreements with SWAPA, TWU 556, and TWU 555, respectively, and a $123 million decrease related to the purchase of fuel derivative instruments, which is included within Other, net operating cash flows in the accompanying Consolidated Statement of Cash Flows. Net cash provided by operating activities is primarily used to finance capital expenditures, repay debt, provide Shareholder returns, and provide working capital.

Net cash used in investing activities for 2025 was $1.4 billion, and net cash used in investing activities for 2024 was $261 million. Investing activities in both years included Capital expenditures and changes in the balance of the Company's short-term and noncurrent investments. Capital expenditures, net were $2.7 billion for 2025, compared with $2.1 billion in the same prior year period, and increased year-over-year largely due to an increase in payments for scheduled aircraft deliveries. Capital expenditures during 2024 included approximately $22 million associated with the Company's purchase of finance leased aircraft. The Company also raised $871 million in 2024 from the sale-leaseback of 35 aircraft. See Note 7 to the Consolidated Financial Statements for further information.

The Company estimates its 2026 net capital spending to be in the range of $3.0 billion to $3.5 billion based on its expectation of 66 -8 aircraft deliveries in 2026, with the remainder representing non-aircraft capital spending, partially offset by proceeds from planned fleet sales. The Company's opportunities to lower net capital spending from its fleet monetization strategy are dependent on aircraft market conditions and Boeing's ability to deliver aircraft pursuant to the Company's contractual order book.

Net cash used in financing activities for 2025 was $4.7 billion, and net cash used in financing activities for 2024 was $2.0 billion. During the twelve months ended December 31, 2025, the Company paid $399 million in cash dividends to Shareholders related to the first, second, and third quarter 2025 and fourth quarter 2024 declarations. Additionally, the Company expended $2.6 billion to repurchase the Company's outstanding common stock through authorized share repurchases during the twelve months ended December 31, 2025. The Company may engage in early debt repurchases from time to time at its discretion; however, no potential early future repurchases are included in the Company's current maturities of long-term debt as of December 31, 2025. During 2025, the Company repaid the Convertible Notes, the PSP1 Payroll Support Program loan, and the PSP2 Payroll Support Program loan in the amounts of $1.6 billion, $976 million, and $566 million, respectively. During fourth quarter 2025, the Company made an early partial prepayment of the PSP3 Payroll Support Program loan in the amount of $100 million utilizing available cash on hand. Additionally, during 2025 the Company issued $750 million senior unsecured notes due 2035 and $750 million senior unsecured notes due 2028. See Note 6 to the Consolidated Financial Statements for further information on the Company's debt repayments, issuances, and future debt maturities. The Company paid $430 million in cash dividends to Shareholders and repaid $1.3 billion in debt and finance lease obligations during the year ended December 31, 2024.

The Company repurchased $2.6 billion of its common stock in 2025 through a series of accelerated share repurchase programs, completing its September 2024 $2.5 billion authorization and leaving $1.7 billion remaining under its July 2025 $2.0 billion authorization as of December 31, 2025. See Note 8 to the Consolidated Financial Statements

for further information on the Company's share repurchases. These purchases were recorded as treasury share repurchases for purposes of calculating earnings per share. Under a forward contract entered into by the Company with a third-party financial institution in fourth quarter 2025, the Company committed $750 million for an Accelerated Share Repurchase Program ("ASR") to be completed in January 2026 (the "January 2026 ASR Program"). On January 2, 2026, the Company paid $750 million and, upon settlement, the third-party financial institution delivered 17,965,193 shares of the Company's common stock to the Company. Upon completion of the January 2026 ASR, the Company had $950 million remaining under its July 2025 $2.0 billion share repurchase authorization. The Company also entered into another agreement to repurchase $400 million of its outstanding common stock through an ASR program entered into in January 2026 (the "First Quarter 2026 ASR Program") under its current $2.0 billion authorization. Final settlement is scheduled to occur by the end of April 2026, and the Company will have $550 million remaining under its $2.0 billion authorization. Subject to certain conditions, repurchases may be made in accordance with applicable securities laws in open market or private, including accelerated repurchase transactions from time to time, depending on market conditions.

A discussion of the Company's most significant drivers impacting cash flow for 2023 are included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2024, under Part II Item 7, Liquidity and Capital Resources.

The Company is a "well-known seasoned issuer" and currently has an effective shelf registration statement registering an indeterminate amount of debt and equity securities for future sales. The Company currently intends to use the proceeds from any future securities sales off this shelf registration statement for general corporate purposes.

Additional detail regarding the Company's available liquidity is provided in the table below.

On July 22, 2025, the Company exercised the accordion feature under its amended and restated revolving credit facility (the "Amended Credit Agreement"), increasing the size of the facility to $1.5 billion. As of December 31, 2025, the Company had access to $1.5 billion under the Amended Credit Agreement, which expires in August 2028. There were no amounts outstanding under the Amended Credit Agreement as of December 31, 2025. See Note 6 to the Consolidated Financial Statements for further information.

As of December 31, 2025, the Company carried a working capital deficit of approximately $5 billion, in which its current liabilities exceed its current assets. This is common within the airline industry and is primarily due to the nature of the Air traffic liability account, which is related to advance ticket sales, unused flight credits available to Customers, and loyalty deferred revenue, which are performance obligations for future Customer flights, do not require future settlement in cash, and are mostly nonrefundable. See Note 5 to the Consolidated Financial Statements for further information.

The Company believes it has various options available to meet its capital and operating commitments, including unrestricted cash and cash equivalents of $3.2 billion as of December 31, 2025, and anticipated future internally generated funds from operations. The Company regularly evaluates its capital structure to efficiently manage financial risks, liquidity access, and cost of capital. The Company may consider, from time-to-time, additional financing arrangements, including secured or unsecured debt, as appropriate. The Company continues to have a large base of unencumbered aircraft and other related assets with a net book value of approximately $17.0 billion. In addition, the Company continues to maintain investment-grade credit ratings by all three major credit agencies (Moody's, S&P Global, and Fitch). As of December 31, 2025, the Company had the following corporate credit ratings:

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

 Moody's S&P Global Fitch <br> Southwest Airlines Co. <u>Baa2</u> <u>BBB</u> <u>BBB+</u>

The Company's capital allocation framework supports its continued commitment to a strong and efficient investment-grade balance sheet. The Company is currently targeting liquidity of approximately $4.5 billion, comprised of cash and cash equivalents, short-term investments, and a revolving credit line, which was recently increased to $1.5 billion. The Company will also target leverage in the range of 1.0 times to 2.5 times, which it calculates as adjusted debt to adjusted EBITDAR.

The following discussion includes various short-term and long-term material cash requirements from known contractual and other obligations, but does not include amounts that are contingent upon events or other factors that are uncertain or unknown at this time. Given the Company's current liquidity position, available resources, and prevailing outlook, it expects to be able to fulfill both its short-term and long-term material cash requirements. The amounts disclosed are based on various estimates, including estimates regarding the timing of payments, prevailing interest rates, volumes purchased, the occurrence of certain events and other factors. Accordingly, the actual results may vary materially from the amounts discussed herein.

*Debt*

As detailed in Note 6 to the Consolidated Financial Statements, in connection with the major negative impact of COVID-19 on air carriers, the Company received significant financial assistance from the United States Department of the Treasury ("Treasury") in the form of payroll support, and this assistance had a significant impact on the Company's reported GAAP financial results through 2021. During 2025, cash flows were impacted through the early repayment of payroll support loans. The Company has approximately $426 million in such loans that will have to be repaid to Treasury in future periods.

See Note 6 to the Consolidated Financial Statements for further detail on the Company's debt and the timing of expected and future principal payments. The Company also has significant future obligations associated with fixed interest payments associated with its debt. As of December 31, 2025, future interest payments associated with its fixed rate unsecured notes were $162 million in 2026, $104 million in 2027, $46 million in 2028, $13 million in 2029, and $7 million in 2030. During fourth quarter 2025, the Company issued $750 million 4.375 percent senior unsecured notes due 2028 and $750 million 5.25 percent senior unsecured notes due 2035. The Company entered into a fixed-to-floating interest rate swap to convert the interest on the 5.25 percent senior unsecured notes due 2035 to a floating rate until their maturity. As of December 31, 2025, based on prevailing forward market interest rates, future interest payments associated with its floating rate unsecured notes were $41 million in 2026, $37 million in 2027, $38 million in 2028, $40 million in 2029, $41 million in 2030, and $223 million thereafter.

*Leases*

The Company enters into leases for aircraft, airports and other real property, and other types of equipment in the normal course of business. See Note 7 to the Consolidated Financial Statements for further detail.

*Aircraft purchase commitments*

The Company is required to make cash deposits toward the purchase of aircraft in advance. These deposits are classified as Deposits on flight equipment purchase contracts in the Consolidated Balance Sheet until the aircraft is delivered, at which time deposits previously made are deducted from the final purchase price of aircraft and are reclassified as Flight equipment. See Part I, Item 2 for a complete table of the Company's contractual firm deliveries and options for -7 and -8 aircraft, and Note 4 to the Consolidated Financial Statements for the financial commitments related to these firm deliveries.

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

*Other*

The Company's other material cash requirements primarily consist of outlays associated with normal operating expenses of the airline, including payroll, fuel, airport costs, etc. While many of these expenses are variable in nature, some of the expenditures can be somewhat fixed in the short-term due to the lead-time involved in publishing the Company's flight schedule in advance and providing for resources to be available to operate those schedules.

The Company has a large net deferred tax liability on its Consolidated Balance Sheet. The deferral of income taxes has resulted in a significant benefit to the Company and its liquidity position. Since the Company purchases the majority of the aircraft it acquires, it has been able to utilize accelerated depreciation methods (including bonus depreciation) available under the Internal Revenue Code of 1986, as amended, in 2025 and in previous years, which has enabled the Company to accelerate cash tax benefits of depreciation. Based on the Company's scheduled future aircraft deliveries from Boeing and existing tax laws in effect, the Company will continue to accelerate the cash income tax benefits related to aircraft purchases. The Company has federal and state operating loss carryforwards of $504 million and $66 million (tax-effected), respectively, to reduce taxable income in future periods. See Note 14 to the Consolidated Financial Statements for further information. The Company has paid in the past, and will continue to pay in the future, cash taxes to the various taxing jurisdictions where it operates. The Company expects to be able to continue to meet such obligations utilizing cash and investments on hand, as well as cash generated from its ongoing operations.

**CRITICAL ACCOUNTING POLICIES AND ESTIMATES**

The Company's Consolidated Financial Statements have been prepared in accordance with GAAP. The Company's significant accounting policies are described in Note 1 to the Consolidated Financial Statements. The preparation of financial statements in accordance with GAAP requires the Company's management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying footnotes. The Company's estimates and assumptions are based on historical experience and changes in the business environment. However, actual results may differ from estimates under different conditions, sometimes materially. Critical accounting policies and estimates are defined as those that both (i) are most important to the portrayal of the Company's financial condition and results and (ii) require management's most subjective judgments. The Company's critical accounting policies and estimates are described below.

***Revenue Recognition***

Tickets sold for Passenger air travel are initially deferred as Air traffic liability. Passenger revenue is recognized and Air traffic liability is reduced when the service is provided (i.e., when the flight takes place). Air traffic liability primarily represents tickets sold for future travel dates, flight credits that are expected to be used in the future, and loyalty program benefits that are expected to be redeemed in the future. Air traffic liability typically fluctuates throughout the year based on seasonal travel patterns, fare sale activity, and activity associated with the Company's loyalty program. See Note 1 to the Consolidated Financial Statements for information about the Company's revenue recognition policies.

For air travel on Southwest, the amount of tickets (which includes flight credits—also referred to as partial tickets) that will go unused, referred to as breakage, is estimated and recognized in Passenger revenue once the scheduled flight date has passed, in proportion to the pattern of rights exercised by the Customer, in accordance with Accounting Standards Codification 606, Revenue From Contracts With Customers ("ASC 606"). Estimating the amount of tickets that will ultimately go unused involves some level of subjectivity and judgment. A significant amount of the Company's tickets sold are nonrefundable, although flight credits created when a Customer cancels or modifies an existing flight itinerary can be applied towards the purchase of future travel. Unused flight credits are the primary source of breakage. Breakage estimates are based on historical experience over many years. Fully refundable tickets rarely go unused.

On July 28, 2022, the Company modified its flight credit policy and announced that all $1.9 billion of unexpired flight credits outstanding as of that date, the majority of which were associated with travel disruptions during the COVID-19 pandemic, would no longer have an expiration date and thus will be able to be redeemed by Customers indefinitely. This change in policy was considered a contract modification under ASC 606 and the Company accounted for such change prospectively in third quarter 2022. Based on actual Customer redemptions of these flight credits throughout 2024, as well as projected redemptions beyond 2024, the Company determined a reversal of a portion of this prior breakage revenue in the amount of $116 million was warranted in fourth quarter 2024. See Note 1 to the Consolidated Financial Statements for further information regarding this adjustment and Note 5 to the Consolidated Financial Statements for further information regarding these extended flight credits. As of December 31, 2025, redemptions of these extended flight credits had declined to an immaterial amount on a monthly basis and the Company has determined that future redemptions of these credits will be immaterial.

On May 28, 2025, the Company again modified its flight credit policy. However, flight credits issued between July 28, 2022, and May 27, 2025 (including those issued subsequent to May 27, 2025, but which related to travel that had already been booked as of that date), do not have an expiration date. For non-expiring flight credits issued during this period, the Company has also been recording breakage for the amount of such flight credits that it does not expect to be redeemed. However, redemptions of these credits are expected to continue for an extended period of time into the future. Although the Company does not currently expect to incur significant breakage adjustments associated with this population of flight credits in future periods, Customer behavior could be different than expected and from prior experience and could thus result in future adjustments, including by a material amount. For every hypothetical one percentage point change in redemption and/or breakage amounts versus what has been

------

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

already recorded associated with these non-expiring flight credits, it would lead to an approximate $79 million change in Passenger revenues.

The majority of flight credits created from reservations booked and ticketed or voluntarily changed on or after May 28, 2025, have a specified expiration date of one year or less, depending on the type of fare purchased. However, with the launch of the new Getaways by Southwest™ ("Getaways") product, the Company has begun to issue vacation travel credits for cancelled bookings, with an 18-month expiration period from the original booking date. The Company is also recording breakage for such credits with expiration dates to the extent it expects them to not be redeemed prior to expiration. Through December 31, 2025, based on actual redemptions and redemption patterns exhibited by Customers thus far, the Company believes its breakage estimates are materially accurate and does not expect future material adjustments associated with these flight credits.

Assumptions about Customer behavior are reviewed frequently and corresponding adjustments are made to breakage estimates, as needed, when observed behaviors differ from historical experience or expectations. Assumptions about Customer behavior can be impacted by several factors including, but not limited to: fare increases, fare sales, changes to the Company's ticketing policies, changes to the Company's refund, exchange, and unused flight credit policies, seat availability, and economic factors. Although the Company's process for estimating breakage has been consistently applied from year to year, it continues to update and refine its analysis and techniques to take into consideration the differing attributes of flight credits as the Company's policies have changed over time. As with any estimates, actual ticket breakage may vary from estimated amounts.

***Loyalty Accounting***

The Company utilizes estimates in the recognition of revenues and liabilities associated with its loyalty program. These estimates primarily include the liability associated with Rapid Rewards loyalty member ("Member") account balances that are expected to be redeemed for travel or other products at a future date. Loyalty account balances include points earned through flights taken, points sold to Customers, or points earned through business partners participating in the loyalty program.

Under the Southwest Rapid Rewards loyalty program, Members earn points for every dollar spent on eligible Southwest fare purchases. The amount of points earned under the program is based on the fare amount and fare type, with higher fare types (e.g., Choice Extra) earning more points than lower fare types (e.g., Basic). Each fare type is associated with a points earning multiplier, and points for flights are calculated by multiplying the fare amount for the flight by the fare type multiplier. Likewise, the amount of points required to be redeemed for a flight can vary depending on destination, time, day of travel, demand, fare type, point redemption rate, and other factors, and is subject to change at any time until the booking is confirmed. Under the program, (i) Members are able to redeem their points for every available seat, every day, on every flight, with no blackout dates; and (ii) points do not expire. In addition, Members are able to redeem their points for items other than travel on Southwest Airlines, such as international flights on other airlines, cruises, hotel stays, rental cars, gift cards, event tickets, and more. In addition to earning points for revenue flights and qualifying purchases with Rapid Rewards Partners, Members also have the ability to purchase, gift, and transfer points, as well as the ability to donate points to selected charities.

The Company utilizes the deferred revenue method of accounting for points earned through flights taken in its loyalty program. The Company also sells points and related services to business partners participating in the loyalty program. Liabilities are recorded for the relative standalone selling price of the Rapid Rewards points which are awarded each period. The liabilities recorded represent the total number of points expected to be redeemed by Members, regardless of whether the Members may have enough to qualify for a full travel award. As of December 31, 2025, the loyalty liabilities were approximately $4.3 billion, including $3.1 billion classified within Air traffic liability and $1.2 billion classified as Air traffic liability – noncurrent.

In order to determine the value of each loyalty point, certain assumptions must be made at the time of measurement, which include an allocation of passenger revenue between the flight and loyalty points earned by passengers, and the fair value of Rapid Rewards points, which are generally based on their redemption value to the Customer. See

Note 5 to the Consolidated Financial Statements for further information on determining the estimated fair value of each loyalty point.

The majority of the points sold to business partners are through the Southwest co-branded credit card agreement ("Agreement") with Chase. Consideration received as part of this Agreement is subject to ASC 606. For periods presented in the Consolidated Financial Statements, the most recent instance in which the Agreement was amended was in 2025. The Company and Chase amended the co-brand credit card agreement in the first quarter of 2025 to extend the term of the agreement and add enhanced airline benefits for Cardmembers associated with the Company's planned assigned seating and premium seating initiative, and again in the second quarter of 2025 to add benefits to Cardmembers related to the Company's changes in its checked bag policy that went into effect on May 28, 2025. Agreements with Chase have the following multiple elements: travel points to be awarded, use of the Southwest Airlines' brand and access to Rapid Rewards Member lists, advertising elements, the use of the Company's resource team, and other airline benefits. These elements are combined into three performance obligations: transportation, marketing, and airline benefits, and consideration from the Agreement is allocated based on the relative selling price of each performance obligation.

Significant management judgment was used to estimate the selling price of each of the performance obligations in the Agreement at inception, including each time in which the Agreement has been materially amended. The objective is to determine the price at which the Company would transact a sale if the product or service was sold on a stand-alone basis. The Company determines the best estimate of selling price by considering multiple inputs and methods including, but not limited to, the estimated selling price of comparable travel, discounted cash flows, brand value, published selling prices, number of points awarded, and the number of points redeemed. The Company estimates the selling prices and volumes over the term of the Agreement in order to determine the allocation of proceeds to each of the multiple performance obligations. The Company records revenue related to air transportation when the travel is delivered, revenue related to marketing elements when the performance obligations related to those services are satisfied, which is generally the same period consideration is received from Chase, and revenue related to airline benefits when they are provided. A hypothetical one percent increase or decrease in the Company's estimate of the standalone selling prices, implemented as of January 1, 2025, causing a change to the allocation of proceeds to air transportation would not have had a material impact on the Company's Operating revenues for the year ended December 31, 2025.

Under its current program, Southwest estimates the portion of loyalty points that will not be redeemed. In estimating breakage revenue, the Company takes into account the Member's past behavior, as well as several factors related to the Member's account that are expected to be indicative of the likelihood of future point redemption. These factors are typically representative of a Member's level of engagement in the loyalty program. They include, but are not limited to, tenure with the program, points accrued in the program, and points redeemed in the program. The Company believes it has obtained sufficient historical behavioral data to develop a predictive statistical model to analyze the amount of breakage expected for all loyalty points. The Company updates this model at least annually, and applies the new breakage rates effective October 1 each year, or more frequently if required by changes in the business. Changes in the breakage rates applied annually in recent years have not had a material impact on Passenger revenues. For the year ended December 31, 2025, based on actual redemptions of points sold to business partners and earned through flights, a hypothetical one percentage point change in the estimated breakage rate would have resulted in a change to Passenger revenue of approximately $256 million (an increase in breakage would have resulted in an increase in revenue and a decrease in breakage would have resulted in a decrease in revenue). Given that Member behavior may fluctuate over time, the Company expects the current estimates may change in future periods. However, the Company believes its current estimates are reasonable given current facts and circumstances.

**Item 7A.&nbsp;&nbsp;&nbsp;&nbsp;*Quantitative and Qualitative Disclosures About Market Risk***

The Company has at times had interest rate risk in its floating-rate debt obligations and interest rate swaps, commodity price risk in jet fuel required to operate its aircraft fleet, and market risk in the derivatives used to manage its fuel hedging program and in the form of fixed-rate debt instruments. As of December 31, 2025, the Company also operated a total of 97 aircraft under operating and finance leases. The Company previously operated a small number of aircraft that had lease payments that fluctuated based in part on changes in market interest rates. The last fluctuating lease expired in July 2025. Therefore, the Company's leases are not considered market sensitive financial instruments and, therefore, are not included in the interest rate sensitivity analysis below. The Company does not purchase or hold any derivative financial instruments for trading purposes. See Note 10 to the Consolidated Financial Statements for information on the Company's financial derivative instruments.

***Hedging and Aircraft Fuel Risk***

Changes in fuel prices could materially affect the Company's results of operations. As discussed in Note 10 to the Consolidated Financial Statements, the Company discontinued its fuel hedging program in 2025. During second quarter 2025, the Company terminated its remaining portfolio of fuel hedging contracts, which were scheduled to settle through 2027, to effectively close its fuel hedging portfolio and program. Consequently, the Company is fully exposed to fluctuations in fuel prices like most of its competitors. The Company currently expects to consume approximately 2.2 billion gallons of jet fuel in 2026. Based on this anticipated usage, a change in jet fuel prices of one cent per gallon would impact the Company's Fuel and oil expense by approximately $22 million for 2026.

The fair values of the derivative instruments held in prior periods, depending on the type of instrument, were determined by use of present value methods or standard option value models with assumptions about commodity prices based on those observed in underlying markets. The Company's credit exposure related to derivative instruments in prior periods was represented by the fair value of contracts that were in an asset position to the Company. At such times, these outstanding instruments exposed the Company to credit loss in the event of nonperformance by the counterparties to the agreements.

The Company has agreements with a majority of its counterparties associated with its outstanding interest rate swap agreements in which cash collateral may be required based on the fair value of outstanding derivative instruments, as well as the Company's and its counterparties' credit ratings. As of December 31, 2025, no cash collateral deposits were provided by or held by the Company based on its outstanding interest rate swap agreements.

***&nbsp;&nbsp;&nbsp;&nbsp;Financial Market Risk***

The vast majority of the Company's tangible assets are aircraft, which are long-lived. The Company's long-term strategy is to maintain an investment grade balance sheet and generate adequate profits and returns on capital, while growing capacity steadily under the right conditions. While the Company uses financial leverage, it strives to maintain a strong and efficient balance sheet and has investment grade credit ratings with all three major credit rating agencies as of December 31, 2025. See Note 6 to the Consolidated Financial Statements for more information on the material terms of the Company's short-term and long-term debt.

<u>[**Table of Contents**](#id4b63aa117ff4ef0ac41217a4f4b5530_7)</u>

All the Company's senior unsecured notes outstanding as of December 31, 2025 were issued as fixed-rate obligations. See Note 6 to the Consolidated Financial Statements for further information.

During fourth quarter 2025, the Company entered into interest rate swap agreements as a hedge related to its $750 million 5.25% Notes due 2035. The primary objective for the Company's use of this interest rate hedge was to hedge against changes in the fair value of the debt instrument caused by changes in market interest rates, specifically SOFR. The hedge strategy is to eliminate the changes in fair value of the debt by converting the fixed rate interest of the debt to a floating rate. Under these interest rate swap agreements, the Company pays SOFR plus a margin every six months on the notional amount of the debt, and receives payments based on the fixed stated rate of the notes every six months until the date the notes become due. These interest rate swap agreements collectively qualify as a fair value hedge. As a result of the fixed-to-floating interest rate swap agreements in place, the average floating rate recognized during 2025 was approximately 5.44 percent, based on actual and forward rates as of December 31, 2025.

The $100 million 7.375% debentures due 2027 had at one point been converted to a floating rate, but the Company subsequently terminated the fixed-to-floating interest rate swap agreements related to it. The effect of this termination was that the interest associated with this debt prospectively reverted back to its original fixed rate. As a result of the gain realized on this transaction, which is being amortized over the remaining term of the corresponding notes, and based on projected interest rates at the date of termination, the Company does not believe its future interest expense, based on projected future interest rates at the date of termination, associated with these notes will significantly differ from the expense it would have recorded had the notes remained at floating rates.

During fourth quarter 2023, the Company terminated $150 million notional value of forward-starting interest rate swap agreements associated with the Company's forecasted issuance of debt. These swap agreements had been classified as cash flow hedges, and all fair market value changes were recorded to AOCI prior to their termination. Following the issuance of the Company's $750 million 5.25% Notes due 2035 in fourth quarter 2025, the deferred gain of $23 million associated with these terminated swaps is now being amortized as a reduction to Interest expense over the life of the notes. See Note 10 to the Consolidated Financial Statements for further information.

The Company's total debt divided by total assets was 16.9 percent as of December 31, 2025.

The Company also has some risk associated with changing interest rates due to the short-term nature of its invested cash, which totaled $3.2 billion, as of December 31, 2025. See Notes 1 and 11 to the Consolidated Financial Statements for further information. The Company currently invests available cash in time deposits, highly rated money market instruments, and other highly rated financial instruments, depending on market conditions and operating cash requirements. Because of the short-term nature of these investments, the returns earned parallel closely with short-term floating interest rates. The Company has not undertaken any additional actions to cover interest rate market risk and is not a party to any other material market interest rate risk management activities.

A hypothetical 10 percent change in market interest rates as of December 31, 2025, would have resulted in an approximate $32 million change in the fair value of the Company's fixed-rate debt instruments. See Note 11 to the Consolidated Financial Statements for further information on the fair value of financial instruments. A change in market interest rates could, however, have a corresponding effect on earnings and cash flows associated with the Company's debt that has been converted to a floating interest rate and invested cash (excluding cash collateral deposits held, if applicable) because of the floating-rate nature of these items. Assuming floating market rates in effect as of December 31, 2025, were held constant throughout a 12-month period, a hypothetical 10 percent change in those rates would have resulted in an immaterial impact on the Company's net earnings and cash flows. Utilizing these assumptions and considering the Company's cash balance (excluding the impact of cash collateral deposits held from or provided to counterparties, if applicable) and floating-rate debt outstanding as of December 31, 2025, an increase in rates would have a net positive effect on the Company's earnings and cash flows, while a decrease in rates would have a net negative effect on the Company's earnings and cash flows. However, a hypothetical 10 percent change in market rates would not impact the Company's earnings or cash flow associated with the Company's publicly traded fixed-rate debt.

The Company is also subject to a financial covenant included in its Amended Credit Agreement, and is subject to credit rating triggers related to its credit card transaction processing agreements, the pricing related to any funds drawn under its Amended Credit Agreement, and some of its hedging counterparty agreements. Certain covenants include the maintenance of minimum credit ratings and/or triggers that are based on changes in these ratings. The Company's Amended Credit Agreement contains a financial covenant to maintain a Coverage Ratio (as defined therein) of 1.25 to 1.00, subject to the Company's one-time option to reduce this ratio requirement to 0.80 to 1.00 for two consecutive fiscal quarters. As of December 31, 2025, the Company was in compliance with this covenant and there were no amounts outstanding under the Amended Credit Agreement. However, if conditions change and the Company fails to meet the minimum standards set forth in the Amended Credit Agreement, there could be a reduction in the availability of cash under the facility, or an increase in the costs to keep the facility intact as written. The Company's hedging counterparty agreements contain ratings triggers in which cash collateral could be required to be posted with the counterparty if the Company's credit rating were to fall below investment grade by two of the three major rating agencies, and if the Company were in a net liability position with the counterparty. See Note 10 to the Consolidated Financial Statements for further information.

The Company currently has agreements with organizations that process credit card transactions arising from purchases of air travel tickets by its Customers utilizing American Express, Discover, and MasterCard/VISA. Credit card processors have financial risk associated with tickets purchased for air travel because the processor generally forwards the cash related to the purchase to the Company soon after the purchase is completed, but the air travel generally occurs after that time; therefore, the processor will have liability if the Company does not ultimately provide the air travel. Under these processing agreements, and based on specified conditions, increasing amounts of cash reserves could be required to be posted with the counterparty. There was no cash reserved for this purpose as of December 31, 2025.

A majority of the Company's sales transactions are processed by Chase Paymentech. Should Customer chargebacks processed by Chase Paymentech reach a certain level, cash proceeds from advance ticket sales could be held back and used to establish a reserve account to cover such chargebacks and any other Customer-disputed charges that might occur. Additionally, cash reserves are required to be established if the Company's credit rating falls to specified levels below investment grade. Cash reserve requirements are based on the Company's public debt rating and a corresponding percentage of the Company's Air traffic liability. As of December 31, 2025, no cash holdbacks were in place.

As of December 31, 2025, the Company was in compliance with all credit card processing agreements. The inability to enter into credit card processing agreements would have a material adverse effect on the business of the Company. The Company believes that it will be able to continue to renew its existing credit card processing agreements or will be able to enter into new credit card processing agreements with other processors in the future.

**1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

***Basis of Presentation***

Southwest Airlines Co. (the "Company" or "Southwest") operates Southwest Airlines, a major domestic airline. The Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. The accompanying Consolidated Financial Statements include the results of operations and cash flows for all periods presented and all significant inter-entity balances and transactions have been eliminated. The preparation of financial statements in conformity with generally accepted accounting principles in the United States ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates.

In late December 2022, Winter Storm Elliott impacted a significant portion of the United States, leading to wide-scale operational disruptions for the Company. In attempting to recover from this weather event, the Company was challenged in its efforts to realign flight crews, flight schedules, and fleet for a period of days during this peak demand travel period. As a result, the Company canceled a significant number of flights between December 21 and December 29, before ultimately returning to a normal flight schedule on December 30, 2022. These canceled flights resulted in a significant reduction in Passenger revenues during this period and also created a deceleration in bookings, primarily isolated to January and February 2023. In addition, the Company incurred significant costs associated with this event, including approximately $55 million of additional expenses during first quarter 2023, which is included in the accompanying Consolidated Statement of Income. Such costs were primarily related to expense reimbursements to Customers impacted by the cancellations and the value of Rapid Rewards points offered as a gesture of goodwill to impacted Customers.

Based on the Company's wide-scale operational disruption, the Company could be subject to fines and/or penalties resulting from investigations by government agencies as well as litigation from Customers and Shareholders. During fourth quarter 2023, the Company reached a settlement with the Department of Transportation (the "DOT") based on their investigation into the disruption, and the Company accrued an associated expense of $107 million. On December 5, 2025, based on the Company's significant improvement to its ontime performance and completion factor since the time of the disruption, and as a result of its significant financial investment in its Network Operations Control function, the DOT waived the final settlement payment of $11 million, originally due January 2026. Other than these transactions, there were no material impacts to operating revenues or expenses as a result of this disruption beyond first quarter 2023.

***Cash and Cash Equivalents***

Cash in excess of that necessary for operating requirements is invested in short-term, highly liquid, income-producing investments. Investments with original maturities of three months or less when purchased are classified as cash and cash equivalents, which primarily consist of money market funds and time deposits issued by major corporations and financial institutions. Cash and cash equivalents are stated at cost, which approximates fair value.

As of December 31, 2025, the Company had no outstanding fuel derivative instruments and therefore no cash collateral deposits associated with its fuel hedge counterparties. Additionally, there were no cash collateral deposits associated with its interest rate hedges as of December 31, 2025. As of December 31, 2024, $22 million in cash collateral deposits were held by the Company from its fuel hedge counterparties, and the Company had no outstanding interest rate swap agreements and therefore no cash collateral deposits associated with its interest rate hedge counterparties. Cash collateral amounts provided or held associated with fuel derivative instruments historically have not been restricted in any way and earned interest income at an agreed upon rate that approximates the rates earned on short-term securities issued by the U.S. Government. See Note 10 for further information on fuel and interest rate derivative instruments.

***Short-term and Noncurrent Investments***

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

Short-term investments consist of investments with original maturities of greater than three months but less than twelve months when purchased. These are primarily short-term securities issued by the U.S. Government and certificates of deposit issued by domestic banks. All of these investments are classified as available-for-sale securities and are stated at fair value, which approximates cost. For all short-term investments, at each reset period or upon reinvestment, the Company accounts for the transaction as Proceeds from sales of short-term and other investments for the security relinquished, and Purchases of short-term investments for the security purchased, in the accompanying Consolidated Statement of Cash Flows. Unrealized gains and losses, net of tax, if any, are recognized in Accumulated other comprehensive income (loss) ("AOCI") in the accompanying Consolidated Balance Sheet. Realized net gains and losses on specific investments, if any, are reflected in Interest income in the accompanying Consolidated Statement of Income. Both unrealized and realized gains and/or losses associated with investments were immaterial for all years presented.

Noncurrent investments consist of investments with maturities of greater than twelve months. Noncurrent investments are included as a component of Other assets in the Consolidated Balance Sheet.

***Accounts and Other Receivables***

Accounts and other receivables are initially recorded at cost and are evaluated for collectability in every period. They primarily consist of the amounts due from the credit card companies associated with sales of tickets for future travel and amounts due from business partners in the Company's loyalty program. See Note 15 for further information. The allowance for doubtful accounts was immaterial as of December 31, 2025 and 2024. In addition, the provision for doubtful accounts and write-offs for 2025, 2024, and 2023 were each immaterial.

***Inventories***

Inventories primarily consist of aircraft fuel and flight equipment expendable parts, materials, and supplies. All of these items are carried at average cost, less an allowance for obsolescence. These items are generally charged to expense when issued for use. The reserve for obsolescence was immaterial as of December 31, 2025, and 2024. In addition, the Company's provision for obsolescence and write-offs for 2025, 2024, and 2023 were each immaterial.

***Property and Equipment***

Property and equipment is stated at cost. Capital expenditures, net include payments made for aircraft, other flight equipment, purchase deposits related to future aircraft deliveries, airport and other facility construction projects, and ground and other property and equipment. Proceeds from the disposition of property and equipment that are retired from service are presented net against capital expenditures, and were immaterial as a component of total capital expenditures for each period presented. Depreciation is provided by the straight-line method to estimated residual values over periods of approximately 25 years for flight equipment, and 5 to 30 years for ground property and equipment. As of December 31, 2025, residual values estimated for aircraft range from 18 percent to 22 percent, and generally range from 0 to 10 percent for ground property and equipment. Assets constructed for others consists of airport improvement projects in which the Company is considered to have control of the asset during the construction period. Once construction is effectively completed, the sale-leaseback model would apply when control passes from the lessee to the lessor. See Note 4 for further information. Leasehold improvements are amortized as a component of depreciation expense over the estimated useful life of the asset or the remaining term of the underlying lease, whichever is less. In certain situations, the term of the lease may include periods covered by renewal options, if renewal is reasonably certain.

The Company evaluates its long-lived assets used in operations for impairment when events and circumstances indicate that the undiscounted cash flows to be generated by that asset group are less than the carrying amounts of the asset group and may not be recoverable. Factors that would indicate potential impairment include, but are not limited to, significant decreases in the market value of the long-lived asset group, a significant change in the long-lived asset group's physical condition, and operating or cash flow losses associated with the use of the long-lived asset group. If an asset group is deemed to be impaired, an impairment loss is recorded for the excess of the asset

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

group's book value in relation to its estimated fair value. There were no material impairments in 2025, 2024, or 2023. In 2024 and 2023, the Company identified certain -700 aircraft that were to be retired earlier than planned through 2025. This change in retirement dates, and the corresponding impact to depreciation expense, is considered a change in estimate and resulted in the following impact to expense in 2024 and 2023:

\* net of profitsharing benefit and income taxes

During third quarter 2025, the Company completed an annual review of the estimated residual values of its long-lived assets. As a result of this review, the Company increased the estimated residual values for its Boeing 737-700 ("-700") airframe and -700, Boeing 737-800 ("-800"), and Boeing 737-8 ("-8") engine assets. This change took into consideration third party valuation data and recent market transactions. As this is considered a change in estimate, it has been accounted for on a prospective basis in accordance with Accounting Standards Codification ("ASC") 205, "Accounting Changes and Error Corrections" and thus the Company will record less depreciation expense over the remainder of the useful lives for each related asset. This change in estimated residual values, and the corresponding impact to depreciation expense resulted in the following impact to expense in the year ended December 31, 2025.

***Leases***

The Company determines if an arrangement is a lease at inception. Operating leases are included in Operating lease right-of-use assets, Current operating lease liabilities, and Noncurrent operating lease liabilities in the Consolidated Balance Sheet. Finance leases are included in Property and equipment, Current maturities of long-term debt, and Long-term debt less current maturities in the Consolidated Balance Sheet.

Right-of-use assets represent the Company's right to use an underlying asset for the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. The lease liability is measured as the present value of the unpaid lease payments, and the right-of-use asset value is derived from the calculation of the lease liability. Lease payments include fixed and in-substance fixed payments, variable payments based on an index or rate, reasonably certain purchase options, termination penalties, fees paid by the lessee to the owners of a special-purpose entity for restructuring the transaction, and probable amounts the lessee will owe under a residual value guarantee. Lease payments do not include (i) variable lease payments other than those that depend on an index or rate, (ii) any guarantee by the lessee of the lessor's debt, or (iii) any amount allocated to non-lease components, if such election was made upon adoption, per the provisions of the ASC 842 Leases. The Company uses its estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments, since the Company does not know the actual implicit rates in its leases. The Company gives consideration to its most recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rate. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. The Company combines lease

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

and non-lease components for all asset groups. The lease term includes any option to extend the lease when it is reasonably certain to be exercised based on considering all relevant economic factors.

***Aircraft and Engine Maintenance***

The cost of scheduled inspections and repairs and routine maintenance costs for all aircraft and engines are charged to Maintenance materials and repairs expense within the accompanying Consolidated Statement of Income as incurred.

The Company has maintenance agreements related to certain aircraft engines with external service providers, including agreements that effectively transfer the risk of performance of such work to the service provider. Under the agreements where the risk of performance is deemed transferred to the counterparty, expense is recorded commensurate with the period in which the corresponding level of service is provided. For its engine maintenance contracts that do not transfer risk to the service provider, the Company records expense on a time and materials basis when an engine repair event takes place.

Modifications that significantly enhance the operating performance or extend the useful lives of aircraft or engines are capitalized and amortized over the remaining life of the asset.

***Goodwill and Intangible Assets***

The Company applies a fair value-based impairment test to the carrying value of goodwill and indefinite-lived intangible assets annually on October 1, or more frequently if certain events or circumstances indicate that an impairment loss may have been incurred. The Company assesses the value of goodwill and indefinite-lived intangible assets under either a qualitative or quantitative approach. Under a qualitative approach, the Company considers various market factors, including applicable key assumptions also used in the quantitative assessment listed below. These factors are analyzed to determine if events and circumstances could reasonably have affected the fair value of goodwill and indefinite-lived intangible assets. If the Company determines that it is more likely than not that an indefinite-lived intangible asset or reporting unit goodwill is impaired, the quantitative approach is used to assess the asset or reporting unit fair value and the amount of the impairment. Under a quantitative approach, the fair value of the Company's indefinite-lived intangible asset or reporting unit is calculated based on key market participant assumptions. If the indefinite-lived intangible assets' carrying value exceeds the fair value calculated using the quantitative approach, an impairment charge is recorded for the difference in fair value and carrying value. If the reporting unit carrying value exceeds the reporting unit fair value calculated using the quantitative approach, an impairment charge is recorded for the difference between fair value and carrying value, limited to the amount of goodwill in the reporting unit.

The Company's intangible assets primarily consist of acquired rights to certain airport owned takeoff and landing slots (a "slot" is the right of an air carrier, pursuant to regulations of the Federal Aviation Administration ("FAA"), to operate a takeoff or landing at a specific time at certain airports) at certain domestic slot-controlled airports. Indefinite-lived slots of $296 million are included as a component of Other assets in the Company's Consolidated Balance Sheet, as of December 31, 2025 and 2024.

The Company applied the qualitative approach during its 2025 impairment tests, and no impairment was determined to exist for Goodwill or indefinite-lived intangible assets.

***Revenue Recognition***

Tickets sold for Passenger air travel are initially deferred as Air traffic liability. Passenger revenue is recognized and Air traffic liability is reduced when the service is provided (i.e., when the flight takes place). Air traffic liability primarily represents tickets sold for future travel dates, flight credits that are expected to be used in the future, and loyalty benefits that are expected to be redeemed in the future. The majority of the Company's tickets sold are nonrefundable. Southwest has a No-Show Policy that applies to fares that are not canceled or changed by a Customer at least 10 minutes prior to a flight's scheduled departure. Nonrefundable tickets that are sold but not

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

flown on the travel date, and are canceled in accordance with the No-Show Policy, can be applied to future travel. Refundable tickets that are sold but not flown on the travel date can also be applied to future travel. A small percentage of tickets (or partial tickets) will go unused, which is sometimes referred to as breakage. The Company estimates the amount of tickets that will go unused and recognizes such amounts in Passenger revenue in proportion to the pattern of flights taken by the Customers, once the flight date has lapsed. Based on the Company's revenue recognition policy, revenue is recorded at the flight date for a Customer who does not change his/her itinerary or does not cancel in accordance with the No-Show Policy as the Company has then fulfilled its performance obligation. Amounts collected from Passengers for ancillary services are also recognized when the service is provided, which is typically the flight date.

On July 28, 2022, the Company modified its policy and announced that all unexpired flight credits as of that date, including flight credits previously extended as a result of the COVID-19 pandemic, no longer had an expiration date and thus would be able to be redeemed by Customers indefinitely. This change in policy was considered a contract modification under ASC 606, and the Company accounted for such change prospectively in third quarter 2022. Due to Customer redemptions of these pre-policy change flight credits that were issued to Customers during 2022 and prior at a higher than projected rate throughout 2024, as well as projected redemptions beyond 2024, the Company determined that a reversal of a portion of prior recorded breakage revenue was warranted. This change in breakage revenue, and the corresponding impact to Passenger revenue, was considered a change in estimate and resulted in the following impact to 2024 results:

---

| | |
|:---|:---|
| **<u>(in millions, except per share amounts)</u>** | **Year ended December 31,**<br>**2024** |
| Breakage revenue adjustment | $(116) |

| Net income per basic share | (0.13) |
| Net income per diluted share | (0.12) |

---

\* net of profitsharing benefit and income taxes

On May 28, 2025, the Company implemented a change to its flight credit policy. Flight credits created from reservations booked and ticketed or voluntarily changed on or after May 28, 2025, will have a specified expiration date of one year or less, depending on the type of fare purchased. Flight credits issued between July 28, 2022, and May 28, 2025, including any future issuances associated with bookings made prior to the policy change on May 28, 2025, will continue to have no expiration date.

Breakage estimates are based on the Company's Customers' historical travel behavior as well as assumptions about their future travel behavior. Assumptions about the Customers' future travel behavior can be impacted by several factors including, but not limited to: fare increases; fare sales; changes to the Company's ticketing policies; changes to the Company's refund, exchange, and unused flight credit policies; seat availability; and economic factors. See Note 5 for further information.

Approximately $756 million, approximately $798 million, and approximately $828 million of the Company's Operating revenues in 2025, 2024, and 2023, respectively, were attributable to foreign operations. The remainder of the Company's Operating revenues, approximately $27.3 billion, approximately $26.7 billion, and approximately $25.0 billion in 2025, 2024, and 2023, respectively, were attributable to domestic operations.

***Loyalty Program***

The Company records a liability for the relative fair value of providing free travel under its loyalty program for all points earned from flight activity or sold to business partners participating in the Company's Rapid Rewards loyalty program. The loyalty liability represents performance obligations that will be satisfied when a Rapid Rewards loyalty Member redeems points and travels or other goods and services are provided. Points earned from flight activity are valued at their relative stand-alone selling price by applying fair value based on historical redemption

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

patterns. Points earned from business partner activity, which primarily consist of points sold, along with related marketing services, to companies participating in the Rapid Rewards loyalty program, are valued using a relative fair value methodology based on the contractual rate which partners pay to Southwest to award Rapid Rewards points to the business partners' customers. For points that are expected to remain unused, the Company recognizes breakage revenue in proportion to the pattern of points used by the Customer, which approximates the average period over which the population of Rapid Reward Members redeem their points. The Company records Passenger revenue related to air transportation when the transportation is delivered, the marketing elements are recognized as Other - net revenue when earned, and the airline benefits are recognized as Passenger revenue when they are provided. The Company's liability for loyalty benefits includes a portion that is expected to be redeemed during the following twelve months (classified as a component of Air traffic liability), and a portion that is not expected to be redeemed during the following twelve months (classified as Air traffic liability - noncurrent). The Company continually updates this analysis and adjusts the split between current and non-current liabilities as appropriate. See Note 5 for further information.

***Advertising***

Advertising costs are charged to expense as incurred. Advertising and promotions expense for the years ended December 31, 2025, 2024, and 2023 was $332 million, $346 million, and $266 million, respectively, and is included as a component of Other operating expense in the accompanying Consolidated Statement of Income.

***Share-based Employee Compensation***

The Company has share-based compensation plans covering certain Employees, including a plan that also covers the Company's Board of Directors. The Company accounts for share-based compensation based on its grant date fair value. See Note 9 for further information.

***Financial Derivative Instruments***

The Company accounts for financial derivative instruments at fair value and applies hedge accounting rules where appropriate. The Company has utilized various derivative instruments, including jet fuel, crude oil, unleaded gasoline, and heating oil-based derivatives, in an attempt to reduce the risk of its exposure to jet fuel price increases. These instruments were accounted for as cash flow hedges upon proper qualification. During second quarter 2025, the Company terminated its remaining portfolio of fuel hedging contracts, which were scheduled to settle through 2027, to effectively close its fuel hedging portfolio and program. See Note 10. The Company also has interest rate swap agreements to convert a portion of its fixed-rate debt to floating rates. These interest rate hedges are appropriately designated as fair value hedges.

Since the Company's financial derivative instruments are not traded on a market exchange, the Company estimates their fair values. Depending on the type of instrument, the values are determined by the use of present value methods or option value models with assumptions based on those observed in underlying markets.

All cash flows associated with purchasing and selling derivatives are classified as operating cash flows in the Consolidated Statement of Cash Flows, within Changes in certain assets and liabilities. The Company classifies any cash collateral provided to or held from counterparties in a "net" presentation on the Consolidated Balance Sheet against the fair value of the derivative positions with those counterparties. See Note 10 for further information.

***Software Capitalization***

The Company capitalizes certain internal and external costs related to the acquisition and development of internal use software during the application development stages of projects. The Company amortizes these costs using the straight-line method over the estimated useful life of the software, which is typically five to fifteen years. Costs incurred during the preliminary project or the post-implementation/operation stages of the project are expensed as incurred. Capitalized computer software, included as a component of Ground property and equipment in the

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

accompanying Consolidated Balance Sheet, net of accumulated depreciation, was $1.3 billion and $1.1 billion as of December 31, 2025, and 2024, respectively. Computer software depreciation expense was $318 million, $271 million, and $246 million for the years ended December 31, 2025, 2024, and 2023, respectively, and is included as a component of Depreciation and amortization expense in the accompanying Consolidated Statement of Income. The Company evaluates internal use software for impairment on a quarterly basis, and if it is determined the value of an asset was not recoverable or it qualifies for impairment, a charge will be recorded to write down the software to the lower of its carrying value or fair value. The Company had no significant impairments during 2025, 2024, or 2023.

***Insurance Reserves***

The Company uses a combination of insurance and self-insurance mechanisms, including a wholly-owned captive insurance entity and participation in a reinsurance treaty, to provide for the potential liabilities associated with certain risks, including workers' compensation, healthcare benefits, general liability, and aviation liability. Liabilities associated with the risks that are retained by the Company are not discounted and are estimated, in part, by considering historical claims experience, demographics, exposure and severity factors, and other actuarial assumptions.

***Income Taxes***

The Company accounts for deferred income taxes utilizing an asset and liability method, whereby deferred tax assets and liabilities are recognized based on the tax effect of temporary differences between the financial statements and the tax basis of assets and liabilities, as measured by current enacted tax rates. The Company also evaluates the need for a valuation allowance to reduce deferred tax assets to estimated recoverable amounts.

The Company uses the portfolio approach for releasing income tax effects associated with amounts reclassified out of AOCI.

The Company's policy for recording interest and penalties associated with uncertain tax positions is to record such items as a component of Income (loss) before income taxes. Penalties are recorded in Other (gains) losses, net, and interest paid or received is recorded in Interest expense or Interest income, respectively, in the accompanying Consolidated Statement of Income. There were no material amounts recorded for penalties and interest related to uncertain tax positions for all years presented. See Note 14 for further information.

On July 4, 2025, the One Big Beautiful Bill Act was signed into law. The legislation did not have a material impact on the Company's income tax expense for the year ended December 31, 2025, nor did it materially change the Company's effective income tax rate for 2025.

***Concentration Risk***

Approximately 84 percent of the Company's Employees are unionized and are covered by collective-bargaining agreements. The Company's last open collective-bargaining labor contract subject to Section 6 of the Railway Labor Act was ratified in December 2024, and all of the Company's collective-bargaining labor contracts are closed until October 2026 when the next labor contract becomes amendable, subject to any early opening of renegotiations.

The Company attempts to minimize its concentration risk with regards to its cash, cash equivalents, and its investment portfolio. This is accomplished by diversifying and limiting amounts among different counterparties, the type of investment, and the amount invested in any individual security or money market fund.

As of December 31, 2025, the Company operated an all-Boeing fleet, all of which are variations of the Boeing 737. The Boeing 737 MAX aircraft ("MAX") are crucial to the Company's growth plans and fleet modernization initiatives. Boeing has in the past experienced, and may continue to experience, delays in fulfilling its commitments with regards to delivery of the -8 to the Company as a result of manufacturing challenges. Further, the Company's contractual delivery schedule for the Boeing 737-7 ("-7") is dependent on the FAA issuing required certifications

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

and approvals to the Boeing Company ("Boeing") and the Company. The FAA will ultimately determine the timing of the -7 certification and entry into service, and the Company therefore offers no assurances that current estimations and timelines are correct.

Boeing no longer manufactures versions of the 737 other than the MAX family of aircraft. If the MAX aircraft were to become unavailable for the Company's flight operations, the Company's growth would be restricted unless and until it could procure and operate other types of aircraft from Boeing or another manufacturer, seller, or lessor, and the Company's operations would be materially adversely affected. In particular, if the Company's growth were to be dependent upon the introduction of a new aircraft make and model to the Company's fleet, the Company would need to, among other things, (i) develop and implement new maintenance, operating, and training programs, (ii) secure extensive regulatory approvals, and (iii) implement new technologies. The requirements associated with operating a new aircraft make and model could take an extended period of time to fulfill and would likely impose substantial costs on the Company. A shift away from a single fleet type could also add complexity to the Company's operations, present operational and compliance risks, and materially increase the Company's costs. Any of these events would have a material, adverse effect on the Company's business, operating results, and financial condition. The Company could also be materially adversely affected if the pricing or operational attributes of its aircraft were to become less competitive.

The Company is also dependent on sole or limited suppliers for aircraft engines and certain other aircraft parts and services. Therefore, it would also be materially adversely impacted in the event of the unavailability of engines, parts and certain repair services, the inability to find adequate support at commercially reasonable terms, or mechanical or regulatory issues associated with such engines or other parts or services.

The Company has historically entered into agreements with some of its co-brand, payment, and loyalty partners that contain exclusivity aspects which place certain confidential restrictions on the Company from entering into certain arrangements with other payment and loyalty partners. These arrangements generally extend for the terms of the agreements, none of which extend beyond October 31, 2031, as of December 31, 2025. Some of these agreements automatically renew on an annual basis, unless either party objects to such extension. In 2025, the Company reached an amended co-brand agreement with JPMorgan Chase Bank USA, N.A. ("Chase")—in the first quarter to extend the term of the agreement and add enhanced airline benefits for Cardmembers associated with the Company's planned assigned seating and premium seating initiative, and again in the second quarter to add benefits to Cardmembers related to the Company's changes in its checked bag policy that went into effect on May 28, 2025. None of these agreements are more than 10 years in length. The Company believes the financial benefits generated by the exclusivity aspects of these arrangements outweigh the risks involved with such agreements.

***Operating Segments and Related Disclosures***

Operating segments are defined as components of an enterprise with separate financial information, which are evaluated regularly by the chief operating decision maker ("CODM") and are used in resource allocation and performance assessments. The Company's CODM is considered to be the Company's President, Chief Executive Officer, & Vice Chairman of the Board of Directors. The Company is managed as a single operating segment that provides air transportation for Passengers and cargo. Managing the Company as one segment allows the Company to benefit from the value of integrated revenue pricing and its route network. The Company's flight equipment, which are all variations of the Boeing 737 series of aircraft, forms one fleet that is deployed through a single route scheduling system to maximize its value. The Company's tangible assets consist primarily of flight equipment, which are mobile across geographic markets and, therefore, have not been allocated.

Financial information and annual operational plans and forecasts are prepared and reviewed by the CODM at the consolidated level. The CODM assesses performance for the Company's single reportable segment and decides how to allocate resources based on Net income. Significant expenses that are regularly provided to the CODM for the Company's one reportable segment are presented in the Consolidated Statement of Income and are included within the operational measure of Net income. There are no additional significant expenses beyond the Consolidated Statement of Income provided to the CODM on a recurring basis. When making operational decisions, the CODM

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

is indifferent to the results on a geographic region basis. The Company's objective in making resource allocation decisions is to optimize the consolidated financial results, such as deciding whether to reinvest profits into parts of the entity, including fleet and network planning, or for other general Corporate purposes, such as shareholder returns.

For single reportable segment-level financial information, total assets, and significant non-cash transactions, see Item 8. Financial Statements.

**2. NEW ACCOUNTING PRONOUNCEMENTS AND ACCOUNTING CHANGES**

On September 18, 2025, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2025-06, Accounting for and Disclosure of Software Costs. The new standard modernizes the guidance to reflect the software development approaches currently being used by removing all references to "development stages" from ASC 350-40 Intangibles—Goodwill and Other - Internal-Use Software. Under ASU 2025-06, only the following criteria in ASC 350-40-25-12(b) and (c) must be met for entities to begin capitalizing software costs: (i) management, with the relevant authority, implicitly or explicitly authorizes and commits to funding a computer software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended (referred to as the "probable-to-complete recognition threshold"). This standard is effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. Entities may apply the guidance prospectively, retrospectively, or via a modified prospective transition method. The Company is evaluating this new standard, but does not expect it to have a significant impact on its financial statement presentation or results.

On November 4, 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This standard requires public companies to disclose, in interim and annual reporting periods, additional information about certain expenses in the notes to the financial statements. This standard is effective for all entities that are subject to Subtopic 220-40, for annual periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, but early adoption is permitted. The Company is evaluating this new standard but does not expect it to have a significant impact on its financial statement disclosures.

On December 14, 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This standard increases transparency and decision usefulness of income tax disclosures for investors by requiring information to better assess how an entity's operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This standard requires entities to provide enhanced disclosures related to the income tax rate reconciliation and income taxes paid. This standard is effective for all entities that are subject to Topic 740, Income Taxes for annual periods beginning after December 15, 2024, but early adoption is permitted. The Company adopted this standard as of January 1, 2025, utilizing the retrospective application as permitted in the standard and has included all required disclosures within this Form 10-K for the year ended December 31, 2025. See Note 14 for further information on the Company's income taxes.

**3. NET INCOME PER SHARE**

The following table sets forth the computation of basic and diluted net income per share (in millions except per share amounts). Basic net income per share is calculated by dividing net income by the weighted average of shares outstanding during the period. Diluted net income per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. An immaterial number of shares related to the Company's restricted stock units were excluded from the denominator for the fiscal years ended December 31, 2024 and 2023 because inclusion of such shares would be antidilutive. There were no antidilutive restricted stock units for the fiscal year ended December 31, 2025. During second quarter 2025, the Company's remaining balance of 1.25 percent Convertible Senior Notes due 2025 (the "Convertible Notes") of

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

$1.6 billion was repaid, settling both principal and accrued interest. Since they were outstanding for a portion of the period prior to repayment, the Convertible Notes had a weighted-average dilutive impact on the net income per share calculation for the year ended December 31, 2025.

**4. COMMITMENTS AND CONTINGENCIES**

***Commitments***

The Company has contractual obligations and commitments primarily with regard to future purchases of aircraft, repayment of debt (see Note 6), and lease arrangements (see Note 7). During the year ended December 31, 2025, the Company entered into supplemental agreements with Boeing relating to its contractual order book for -7 and -8 aircraft. The Company's contractual order book with Boeing for -7 and -8 aircraft, which extends to 2031, was designed to support the Company's growth and fleet modernization plans, while also providing significant flexibility and optionality to manage its fleet gauge and size, including opportunities to accelerate fleet modernization efforts if growth opportunities do not materialize. The Company received 55 -8 aircraft deliveries from Boeing in 2025 and retired 48 -700 aircraft and seven -800 aircraft, including the sale of five -800 aircraft. During fourth quarter 2025, the Company exercised six -7 options for delivery in 2027, converted one 2025 -7 firm order into a 2025 -8 firm order, and converted 12 2026 -7 firm orders into 2026 -8 firm orders.

Boeing continues to experience delays in fulfilling its commitments with regards to delivery of MAX aircraft to the Company and delays in achieving FAA certification of one of its new aircraft types, the -7, for which Southwest expects to be the launch customer. During 2025, as a result of Boeing's ongoing delivery delays, the Company conservatively re-planned its capacity and delivery expectations for 2026. The Company will continue to closely monitor the ongoing aircraft delivery delays with Boeing and adjust expectations as needed.

Based on the Company's current agreement with Boeing, capital commitments associated with its firm orders as of December 31, 2025 were:

---

|:---|:---|:---|:---|:---|:---|:---|:---|:---|
| **(in billions)** | **2026** |  | **2027** | **2028** | **2029** | **2030** | **2031** | **Total** |
| Payments for capital commitments | $4.2 | (a) | $2.7 | $2.7 | $2.5 | $1.5 | $1.2 | $14.8 |

---

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

(a) Capital commitments associated with the Company's firm orders in 2026 of $4.2 billion include approximately $2.5 billion primarily related to the existing scheduled 86 MAX aircraft to be delivered in 2026 and $1.7 billion related to 81 MAX aircraft (27 -7s and 54 -8s) that were contractually committed for 2024 and 2025, but were not received.

In addition, subsequent to December 31, 2025, and through February 5, 2026, the Company exercised four -7 options for delivery in 2027, resulting in an increase of the Company's 2027 capital commitments to $2.8 billion.

**Los Angeles International Airport**

In April 2023, the Company executed a lease agreement with Los Angeles World Airports ("LAWA"), which owns and operates Los Angeles International Airport ("LAX"), for the ground lease and construction of a new concourse. In this agreement, the Company will manage the development, design, financing, and construction of nine new gates, along with additional features, at LAX. Construction of the concourse is estimated to not exceed $2.3 billion. During 2024, the Company's leadership met with LAWA and agreed to pause the project, with plans to restart it in 2026. The Company expects to commence construction in 2028 with construction to be completed in 2032.

Funding for this project will flow through a credit facility and the outstanding loans are expected to be paid off directly by LAWA to the credit facility at project completion, thus reimbursing the Company on all costs drawn on the credit facility. As of December 31, 2025, the credit facility has yet to be put into place and is expected to be established closer to the beginning of construction in 2028. The Company is expected to be reimbursed by the credit facility on prior payments made once in place.

Based on this agreement, the Company has determined that it does have control over the assets during this project for accounting purposes. As a result, the costs incurred to fund this project thus far, which totaled $88 million as of December 31, 2025, are included within Assets constructed for others on the accompanying Consolidated Balance Sheet.

**William P. Hobby Airport**

In March 2022, the Company executed a Memorandum of Agreement ("MOA") with the City of Houston, Texas (the "City") which owns William P. Hobby Airport ("Hobby") that is managed and operated by the City's Houston Airport System. Under the MOA, the Company will manage the development, design, and construction of seven new gates in Hobby's West Concourse.

The project is currently estimated to be completed in 2027 at a cost of at least $470 million. The Company is providing initial funding for the majority of the project, but is being reimbursed for such funding from the City on a monthly basis and therefore the project has not and is not expected to significantly impact the Company's liquidity. The City plans to fund these reimbursements utilizing rates and charges collected from current and future Hobby occupants, including the Company.

Based on the MOA, as well as an amendment to the terminal lease agreement signed in August 2023, the Company has determined that it does not control the assets during the construction period for accounting purposes, and thus is recording the amounts funded for the project as a receivable until reimbursed by the City, at which time the balance is derecognized. A balance of $88 million was reflected within Accounts and other receivables in the accompanying Consolidated Balance Sheet as of December 31, 2025.

***Contingencies***

The Company is from time to time subject to various legal proceedings and claims arising in the ordinary course of business and records a liability for such claims when it is probable that a loss will be incurred and the amount is reasonably estimable.

The Company is a defendant in class action litigation asserting it has not provided paid short-term military leave to certain Employees, in violation of the federal Uniformed Services Employment and Reemployment Rights Act ("USERRA"). The United States District Court for the Northern District of California previously issued an order to

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

effectively stay the action, pending an appeal from an order by the United States District Court for the Eastern District of Washington granting summary judgment in favor of an airline in a separate case involving substantially the same claims at issue in this action. On February 1, 2023, the Ninth Circuit reversed the district court's grant of summary judgment and remanded the separate airline case to the District Court. The Ninth Circuit's decision may adversely affect the Company's defenses in the USERRA proceeding and may give rise to additional litigation in this or other areas. On October 29, 2024, the Company filed a motion to decertify the class. On February 13, 2025, the parties filed a notice of settlement advising the Court that they reached a settlement in principle, and the parties made a stipulated request for the Court to vacate the case schedule, including the hearing on the Company's decertification motion, and to set a deadline of June 19, 2025, for the filing of either a motion for preliminary approval of the class settlement or a status update about the timing of the remaining steps in the settlement process. The Court granted the stipulation on February 14, 2025. On June 20, 2025, the Court granted the parties' stipulated request to continue the deadline for filing a motion for preliminary approval of the class settlement. On September 25, 2025, plaintiffs filed a motion for preliminary approval of the settlement class. The settlement includes an $18.5 million settlement fund and prospective relief that includes a differential pay benefit for up to 10 days of military leave per year, which will remain in place for at least five years once initiated. On December 11, 2025, the Court granted preliminary approval of the settlement and set the final approval hearing for May 14, 2026. The proposed settlement is fully accrued as of December 31, 2025.

On December 27, 2019, a former Customer Service Agent at Oakland International Airport, filed a putative class action complaint in the Superior Court of California, for the County of Santa Clara, against the Company alleging the following seven claims under the California Labor Code and Business & Professions Code: (1) failure to provide meal periods; (2) failure to provide rest periods; (3) failure to pay hourly wages; (4) failure to provide accurate wage statements; (5) failure to timely pay all final wages; (6) unfair competition; and (7) civil penalties for the foregoing. Plaintiff filed a First Amended Complaint on October 15, 2021, that asserted the same causes of action and added a named plaintiff. The First Amended Complaint primarily seeks unpaid wages, interest thereon, and associated civil and statutory penalties, along with attorneys' fees and costs. On February 26, 2025, the Court granted class certification as to the first cause of action for failure to provide meal periods, denied certification on the second through fourth causes of action, and granted certification on the fifth and sixth causes of action only insofar as they are predicated on the first cause of action. The certified class consists of all of the Company's non-exempt ground Employees in California who worked a shift in excess of five hours for the time period between October 24, 2014, forward. On April 17, 2025, the Company filed a summary judgment motion arguing that Plaintiffs' first cause of action, and all causes of action predicated thereon, failed as a matter of law. The motion was granted on July 25, 2025. Judgment was entered in favor of the Company on September 2, 2025, and Plaintiffs filed a notice of appeal on September 4, 2025. The Company is currently not able to estimate a range of possible loss with regards to the litigation to which it is a defendant.

**5. REVENUE**

**Passenger Revenues**

The Company's contracts with its Customers primarily consist of its tickets sold, which are initially deferred as Air traffic liability. Passenger revenue associated with tickets is recognized when the performance obligation to the Customer is satisfied, which is primarily when travel is provided.

Revenue is categorized by revenue source as the Company believes it best depicts the nature, amount, timing, and uncertainty of revenue and cash flow. The following table provides the components of Passenger revenue recognized for the years ended December 31, 2025, 2024, and 2023:

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

---

| | | | |
|:---|:---|:---|:---|
| | **Year ended December 31,** | **Year ended December 31,** | **Year ended December 31,** |
| **<u>(in millions)</u>** | **2025** | **2024** | **2023** |
| Passenger non-loyalty | $20441 | $20467 | $19073 |
| Passenger loyalty - air transportation | 3259 | 3484 | 3639 |
| Passenger ancillary sold separately | 1835 | 1029 | 925 |
| &nbsp;&nbsp;**Total passenger revenues** | $25535 | $24980 | $23637 |

---

Passenger non-loyalty includes all revenues recognized from Passengers for flights purchased primarily with credit card. Passenger loyalty - air transportation primarily consists of the revenue associated with award flights taken by loyalty program Members upon redemption of loyalty points. Passenger ancillary sold separately includes any revenue associated with ancillary fees charged separately, such as in-flight purchases, baggage fees, EarlyBird Check-In<sup>®</sup>, and Upgraded Boarding.

In order to determine the value of each loyalty point in a flight transaction, certain assumptions must be made at the time of measurement, which include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Allocation of Passenger Revenue* - Revenues from Passengers, related to travel, who also earn Rapid Rewards points have been allocated between flight (recognized as revenue when transportation is provided) and loyalty (deferred until points are redeemed) based on each obligation's relative stand-alone selling price. The Company utilizes historical earning patterns to assist in this allocation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Fair Value of Rapid Rewards Points* - Determined from the base fare value of tickets which were purchased using prior point redemptions for travel and other products and services, which the Company believes to be indicative of the fair value of points as perceived by Customers and representative of the value of each point at the time of redemption. The Company's booking site allows a Customer to toggle between fares utilizing either cash (or equivalent) or point redemptions, which provides the Customer with an approximation of the equivalent value of their points. The value can differ, however, based on demand, the amount of time prior to the flight, and other factors. The mix of fare classes during the period measured represents a constraint, which could result in the assumptions above changing at the measurement date, as fare classes can have different coefficients used to determine the total loyalty points needed to purchase an award ticket. The mixture of these fare classes and changes in the coefficients used by the Company could cause the fair value per point to fluctuate.

The Company allocates consideration received to performance obligations based on the relative fair value of those obligations. The Company maintains a decades-long relationship with and has a co-branded credit card agreement ("Co-brand Agreement") with Chase, through which the Company sells loyalty points and certain marketing components, which consist of the use of the Southwest Airlines brand and access to Rapid Rewards Member lists, licensing and advertising elements, the use of the Company's resource team, and other airline benefits. In 2025, the Company and Chase amended the Co-brand Agreement—in the first quarter to extend the term of the agreement and add enhanced airline benefits for Cardmembers associated with the Company's planned assigned seating and premium seating initiative, and again in the second quarter to add benefits to Cardmembers related to the Company's changes in its checked bag policy that went into effect on May 28, 2025. For each change to the Co-brand Agreement, the Company estimated the selling prices and volumes over the term of the Co-brand Agreement in order to determine the allocation of proceeds to each of the three performance obligations identified in the Co-brand Agreement, which have been characterized as a transportation component, a marketing component, and an airline benefits component. The allocations utilized are reviewed to determine if adjustment is necessary any time there is a modification to the Co-brand Agreement. The Company records Passenger revenue related to loyalty point redemptions for air travel when the travel is delivered, the marketing elements are recognized as Other revenue when the performance obligations related to those services are satisfied, which is generally the same period consideration is received from Chase, and the airline benefits are recognized primarily within Passenger revenue when those performance obligations are satisfied. As a result of the 2025 amendments to the Co-brand Agreement, a larger portion of the Company's co-brand credit card benefits from Chase are now being classified within Passenger revenues.

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

For points that are expected to remain unused, the Company recognizes breakage in proportion to the pattern of points used by the Customer, which approximates the average period over which the population of Rapid Reward Members redeem their points. The Company utilizes historical behavioral data to develop a predictive statistical model to analyze the amount of expected breakage for points sold to business partners and earned through flight. The Company continues to evaluate expected breakage annually and applies appropriate adjustments in the fourth quarter of each year, or other times, if significant changes in Customer behavior are detected. Changes to breakage estimates impact revenue recognition prospectively. Due to the size of the Company's liability for loyalty benefits, changes in Customer behavior and/or expected future redemption patterns could result in significant variations in Passenger revenue.

As performance obligations to Customers are satisfied, the related revenue is recognized. The events that result in revenue recognition that are associated with performance obligations identified as a part of the Rapid Rewards loyalty program are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Tickets and Rapid Rewards Points* - When a flight occurs, the related performance obligation is satisfied and the related value provided by the Customer, whether from purchased tickets, Rapid Rewards points, or a combination thereof, is recognized as Passenger revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Loyalty Points Redeemed for Goods and/or Services Other Than Travel* - Rapid Rewards Members have the option to redeem points for goods and services offered through a third-party vendor, who acts as principal. The performance obligation related to the purchase of these goods and services is satisfied when the good and/or service is delivered to the Customer as a component of Other revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Marketing Royalties* - As part of its Co-brand Agreement with Chase, Southwest provides certain deliverables, including use of the Southwest Airlines' brand, access to Rapid Rewards Member lists, advertising elements, and the Company's resource team. These performance obligations are satisfied each month that the Co-brand Agreement is active and are recognized as a component of Other revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Travel-Related Services* - Travel-related services are primarily composed of services performed in conjunction with a passenger's flight, including checked baggage, seat, and other on-board benefits. The Company recognizes Passenger revenue for these services when the related transportation service is provided.

As of the years ended December 31, 2025 and 2024, the components of Air traffic liability, including contract liabilities based on tickets sold and unused flight credits available to the Customer, both of which are net of recorded breakage, and loyalty points available for redemption, within the Consolidated Balance Sheet were as follows:

| Air traffic liability - loyalty program | 4334 | 4849 |
| &nbsp;&nbsp;**Total Air traffic liability** | $7164 | $8242 |

---

The balance in Air traffic liability - passenger travel and ancillary passenger services also includes flight credits not currently associated with a ticket that can be applied by Customers towards the purchase of future travel. These flight credits are typically created as a result of a prior ticket cancellation or exchange, and are reflected net of associated breakage. Rollforwards of the Company's Air traffic liability - loyalty program for the years ended December 31, 2025 and 2024 were as follows (in millions):

On July 28, 2022, the Company announced that all existing Customer flight credits as of that date, as well as any future flight credits issued, no longer expire and will thus remain redeemable by Customers. The Company's balance of existing Customer flight credits as of the modification date was approximately $1.9 billion, including a portion of the extended flight credits issued during the early portion of the COVID-19 pandemic. The Company determined a $116 million reversal of a portion of prior breakage revenue was warranted for the twelve months ended December 31, 2024. This was due to continued redemptions for flight credits issued prior to the modification date during 2024 as well as projected redemptions at that time. This change in breakage revenue, and the corresponding impact to passenger revenue, is considered a change in estimate (see Note 1 for further information).

On May 28, 2025, the Company implemented a change to its flight credit policy. Flight credits created from reservations booked and ticketed or voluntarily changed on or after May 28, 2025, will have a specified expiration date of one year or less, depending on the type of fare purchased. Flight credits issued between July 28, 2022, and May 28, 2025, including any future issuances associated with bookings made prior to the policy change on May 28, 2025, do not have an expiration date. The Company also began to issue vacation travel credits for cancelled bookings resulting from the launch of the new Getaways by Southwest™ ("Getaways") product, and these credits will have an 18-month expiration period from original booking date. As the Company believes that a portion of Customer travel credits (both flight credits and Getaways travel credits) issued will not be redeemed, it estimates and records breakage associated with such amounts.

The amount of Customer flight credits represents approximately 5 percent and 8 percent of the total Air traffic liability balance as of December 31, 2025, and December 31, 2024, respectively.

Recognition of revenue associated with the Company's loyalty liability can be difficult to predict, as the number of award seats available to Members is not currently restricted and Members could choose to redeem their points at any time that a seat is available. The performance obligations classified as a current liability related to the Company's loyalty program were estimated based on expected redemptions utilizing historical redemption patterns, and forecasted flight availability and fares. The entire balance classified as Air traffic liability-noncurrent relates to loyalty points that were estimated to be redeemed in periods beyond the twelve months following the representative balance sheet date. Based on historical experience as well as current forecasted redemptions, the Company expects the majority of loyalty points to be redeemed within approximately one year of the date the points are issued. The

Company's policy change on flight credit expirations for any reservations booked and ticketed or voluntarily changed on or after May 28, 2025, will generally have satisfied the performance obligation duration of twelve months or less. For all other flight credits created under the prior policy, the Company currently does not expect the amount of flight credits that will be redeemed beyond twelve months to be material as a percentage of the Air traffic liability as of the financial statement date.

All performance obligations related to freight services sold are completed within twelve months or less; therefore, the Company has elected to not disclose the amount of the remaining transaction price and its expected timing of recognition for freight shipments.

Other revenues primarily consist of marketing royalties associated with the Company's co-brand Chase<sup>®</sup> Visa credit card program, but also include commissions and advertising associated with Southwest.com. All amounts classified as Other revenues are paid monthly, coinciding with the Company fulfilling its deliverables; therefore, the Company has elected to not disclose the amount of the remaining transaction price and its expected timing of recognition for such services provided.

The Company recognized revenue related to the marketing, advertising, and other travel-related benefits of the cash flows associated with various loyalty partner agreements including, but not limited to, the Co-brand Agreement with Chase, the majority of which is within Other operating revenues. For the years ended December 31, 2025, 2024, and 2023 the Company recognized $2.6 billion, $2.2 billion, and $2.1 billion, respectively. The increase in revenue recognized in 2025 was primarily driven by immediate recognition of a larger portion of revenues (and thus lower revenue deferred) associated with the Company's aforementioned co-brand agreement with Chase from 2025 modifications to the agreement, which has also resulted in a lower balance in Air traffic liability as of December 31, 2025, as compared to the prior year.

The Company is also required to collect certain taxes and fees from Customers on behalf of government agencies and remit these back to the applicable governmental entity on a periodic basis. These taxes and fees include foreign and U.S. federal transportation taxes, federal security charges, and airport passenger facility charges. These items are collected from Customers at the time they purchase their tickets, are excluded from the contract transaction price, and are therefore not included in Passenger revenue. The Company records a liability upon collection from the Customer and relieves the liability when payments are remitted to the applicable governmental agencies.&nbsp;&nbsp;&nbsp;&nbsp;

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

On May 1, 2020, the Company completed the public offering of $2.3 billion aggregate principal amount of the Convertible Notes, bearing interest at a rate of 1.25 percent, payable semi-annually in arrears. The Company repurchased $689 million during the two year period ending December 31, 2022, and the remaining $1.6 billion principal amount of the Convertible Notes was repaid at maturity during second quarter 2025 utilizing available cash on hand.

| Total interest expense | $10 | $30 |

---

The unamortized debt issuance costs were recognized as non-cash interest expense based on the 5-year term of the notes, through May 1, 2025, less amounts that were required to be accelerated immediately upon conversion or repurchases. The Company had no changes to contingencies with regards to the Convertible Notes through the settlement date, May 1, 2025.

***Payroll Support Program Loans due through 2031***

During 2020 and 2021, the Company entered into definitive documentation with the United States Department of the Treasury ("Treasury") with respect to payroll funding support ("Payroll Support") pursuant to three separate Payroll Support programs: the "PSP1 Payroll Support Program" in April 2020 under the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"); the "PSP2 Payroll Support Program" in January 2021 under the Consolidated Appropriations Act, 2021; and the "PSP3 Payroll Support Program" in April 2021 under the American Rescue Plan Act of 2021.

As consideration for its receipt of funding under each of these Payroll Support programs, the Company issued promissory notes in favor of Treasury (each initially classified as a component of Long-term debt less current maturities in the unaudited Condensed Consolidated Balance Sheet). The note associated with the PSP1 Payroll Support Program was originally due in April 2030 but was redeemed early on April 17, 2025, in the amount of $976 million. The note associated with the PSP2 Payroll Support Program was originally due in January 2031 but was redeemed early on December 29, 2025, in the amount of $566 million. The note associated with the PSP3 Payroll Support Program is due in April 2031. On December 30, 2025, the Company made a partial prepayment on the note associated with the PSP3 Payroll Support Program in the amount of $100 million. All payments were made utilizing available cash on hand.

On the day after the fifth anniversary of the note associated with the PSP3 Payroll Support Program during April 2026, the applicable interest rate is scheduled to change to SOFR plus two percent.

***Revolving Credit Facility***

As of December 31, 2025, the Company has access to $1.5 billion under its amended and restated revolving credit facility (the "Amended Credit Agreement"), which expires in August 2028, reflecting the Company's exercise of the accordion feature to increase the size of the facility on July 22, 2025. For the twelve months ended December 31, 2025 and 2024 there were no amounts outstanding under the Amended Credit Agreement.

Generally, amounts outstanding under the Amended Credit Agreement bear interest at rates based on either the SOFR rate (selected by the Company for designated interest periods) or the "alternate base rate" (being the highest of (1) the Wall Street Journal prime rate, (2) one-month adjusted SOFR (one-month SOFR plus 0.1 percent) plus 1 percent, and (3) the Federal Reserve Bank of New York Rate, plus 0.5 percent). The underlying SOFR rate is subject to a floor of 1 percent per annum and the "alternate base rate" is subject to a floor of 1 percent per annum.

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

The facility contains a financial covenant requiring a minimum coverage ratio of adjusted pre-tax income to fixed obligations, as defined. As of December 31, 2025, the Company was in compliance with this covenant and all other covenants in the Amended Credit Agreement.

The Company is required to provide standby letters of credit to support certain obligations that arise in the ordinary course of business. Although the letters of credit are an off-balance sheet item, the majority of the obligations to which they relate are reflected as liabilities in the Consolidated Balance Sheet. Outstanding letters of credit totaled $272 million as of December 31, 2025.

The Company had no assets pledged as collateral for its borrowings as of December 31, 2025.

***Maturities***

**7. LEASES**

The Company enters into leases for aircraft, property, and other types of equipment in the normal course of business. As allowed under ASC 842, Leases, the Company has elected a practical expedient to exclude from recognition lease assets and lease liabilities associated with leases that have an initial term of twelve months or less. Such expense was not material for the twelve months ended December 31, 2025, 2024, and 2023.

As of December 31, 2025, the Company held aircraft leases with remaining terms extending up to eight years. The aircraft leases generally can be renewed for three months to three years at rates based on the fair market value at the end of the lease term. Residual value guarantees included in the Company's lease agreements are not material. The lease return costs incurred by the Company for returns completed in 2025 were $33 million, recognized as a component of Other operating expenses but were not material for all other periods presented.

In fourth quarter 2024, the Company entered into an agreement with UMB Bank, N.A. ("UMB Bank") involving the sale of 36 of the Company's -800 aircraft that qualified as sale-leaseback arrangements under applicable accounting guidance. Of the 36 -800 sale-leasebacks, 35 were executed in fourth quarter 2024 and one was executed in first quarter 2025. The Company sold the 35 -800 aircraft in fourth quarter 2024 to UMB Bank for $871 million, then immediately leased the aircraft back for approximately two to three years. In first quarter 2025, the Company sold one -800 aircraft to UMB Bank for $24 million, then immediately leased the aircraft back for approximately three years. As such, 36 aircraft were de-recognized from Property and equipment at their remaining net book values at the time of sale. All of the leases from the sale-leasebacks are accounted for as operating leases, and thus are now reflected as part of the Company's Operating lease right-of-use assets and operating lease liabilities in the accompanying Consolidated Balance Sheet. The -800 sale-leaseback transaction resulted in a recognized gain of $92 million and operating lease right-of-use assets and liabilities of $319 million in fourth quarter 2024 and resulted in a recognized gain of $3 million and operating lease right-of-use assets and liabilities of $9 million in first quarter

2025. These gains were reflected within Other operating expenses, net in the accompanying Consolidated Statement of Comprehensive Income.

Throughout 2024, the Company entered into agreements with third parties to purchase two -700 aircraft, both of which were already in the Company's fleet under finance lease terms, one -800 aircraft, and the airframe of one -800 aircraft, both of which were already in the Company's fleet under operating lease terms. The Company paid the lessors $45 million in 2024, of which $3 million was recorded as the elimination of the Company's remaining finance lease obligation for the aircraft, and which was also reflected within Payments of long-term debt and finance lease obligations in the accompanying Consolidated Statement of Cash Flows and $2 million was recorded as the elimination of the Company's remaining operating lease obligation for the aircraft, and which was also reflected within Changes in Other noncurrent assets in the accompanying Consolidated Statement of Cash Flows. The remaining $40 million was the net purchase price of the aircraft and is included as part of the Company's Capital expenditures for 2024. There was no gain or loss recorded as a result of these transactions. As of December 31, 2025, the Company has 82 operating and 15 finance leased aircraft remaining in its fleet.

In second and third quarter 2023, the Company also entered into additional transactions with third parties to purchase four -700 aircraft, all of which were already in the Company's fleet under finance lease terms. The Company paid the lessors $44 million in 2023, of which $3 million was recorded as the elimination of the Company's remaining finance lease obligation for the aircraft, and which was also reflected within Payments of long-term debt and finance lease obligations in the accompanying Consolidated Statement of Cash Flows. The remaining $41 million was the net purchase price of the aircraft and is included as part of the Company's Capital expenditures for 2023. There was no gain or loss recorded as a result of these transactions.

In first quarter 2023, the Company completed the purchase of eight -700 aircraft from an aircraft sale agreement with AerCap Ireland Limited ("AerCap") to purchase a total of 39 -700 aircraft, all of which were already in the Company's fleet under finance lease terms. The Company completed the purchase of the other 31 of these aircraft during fourth quarter 2022. The Company paid the lessor 88 million in first quarter 2023 as part of this transaction, of which $50 million was recorded as the elimination of the Company's remaining finance lease obligation for the aircraft, and which was also reflected within Payments of long-term debt and finance lease obligations in the accompanying Consolidated Statement of Cash Flows. The remaining $38 million was the net purchase price of the aircraft and is included as part of the Company's Capital expenditures for first quarter 2023. There was no gain or loss recorded as a result of these transactions.

At each airport where the Company conducts flight operations, the Company has lease agreements, generally with a governmental unit or authority, for the use of airport terminals, airfields, office space, cargo warehouses, gates, and/or maintenance facilities. These leases are classified as operating lease agreements and have remaining lease terms extending up to 35 years. Certain leases can be renewed from one year to 11 years. The majority of the airport terminal leases contain certain provisions for periodic adjustments to rates that depend upon airport operating costs or use of the facilities, and are reset at least annually. Because of the variable nature of these rates, these leases are not recorded as a right-of-use asset or a lease liability on the Consolidated Balance Sheet.

The Company also leases certain technology assets, fuel storage tanks, and various other equipment that qualify as leases under the applicable accounting guidance with lease terms extending up to five years. Certain leases can be renewed to one year.

average price per share of the Company's common stock during a calculation period to be completed at the time of settlement.

**9. STOCK PLANS**

***Share-based Compensation***

The Company accounts for share-based compensation utilizing fair value, which is determined on the date of grant for all instruments. The Consolidated Statement of Income for the years ended December 31, 2025, 2024, and 2023, reflects share-based compensation expense of $99 million, $45 million, and $86 million, respectively. The total tax impact recognized in earnings from share-based compensation arrangements for the years ended December 31, 2025, 2024, and 2023, was not material. As of December 31, 2025, there was $100 million of total unrecognized compensation cost related to share-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.9 years. The Company expects substantially all unvested shares associated with time-based restricted stock unit awards to vest.

***Restricted Stock Units and Stock Grants***

Under the Company's Amended and Restated 2007 Equity Incentive Plan ("2007 Equity Plan"), which was approved by Shareholders, the Company granted restricted stock units ("RSUs") and performance-based restricted stock units ("PBRSUs") to certain Employees during 2025, 2024, and 2023.

The RSUs are scheduled to vest with respect to one-third of the shares covered thereby annually. Other than in connection with death or disability, vesting is subject to the individual's continued service as an Employee, Board member, or advisor through the vesting date. However, with respect to the RSUs granted in 2023, 2024, and 2025, provided that the individual's service has terminated no earlier than 12 months after the date of grant, in the event of a "qualified retirement," any outstanding unvested RSUs will remain outstanding as if the individual's service has not terminated and will continue to vest in accordance with the schedule set forth in the notice of the grant. An individual's termination of service will be considered a "qualified retirement" if (a) the individual has completed at least 10 years of continuous service; (b) the individual's age plus completed years of continuous service equal at least 65 at the time of the individual's termination of service; and (c) the individual has not been terminated for cause.

Under the 2023 grants, the number of PBRSUs vesting on the vesting date will be interpolated based on the Company's Adjusted ROIC performance, as defined, and ranges from zero to 200 percent of granted PBRSUs, only after a minimum performance level has been achieved. Adjusted ROIC for the Performance Period is the average of the ROIC, using an assumed federal tax rate of 24 percent, over the three full fiscal years within the Performance Period (2023, 2024, and 2025), and vesting is also subject generally to the individual's continued employment or service. However, in the event the Company's average Adjusted ROIC is greater than zero and exceeds the median (i.e., 50th percentile) return on invested capital of certain of the Company's Peer Group of domestic mainline carriers subject to the Securities and Exchange Commission's reporting requirements, the minimum number of PBRSUs that will vest, as of the vesting date, will be equal to the grant amount times 50 percent. If the Company's relative Adjusted ROIC ranks highest compared to the Company's Peer Group, the minimum number of PBRSUs that will vest, as of the vesting date, will be equal to the grant amount times 100 percent.

Under the 2024 grants, the number of PBRSUs vesting on the vesting date will be interpolated based on the Company's Adjusted ROIC performance, as defined, and ranges from zero to 200 percent of granted PBRSUs, only after a minimum performance level has been achieved. Adjusted ROIC for the Performance Period is the average of the ROIC, using an assumed federal tax rate of 24 percent, over the three full fiscal years within the Performance Period (2024, 2025, and 2026), and vesting is also subject generally to the individual's continued employment or service. However, in the event the Company's average Adjusted ROIC is greater than zero and exceeds the median (i.e., 50th percentile) return on invested capital of certain of the Company's Peer Group of domestic mainline carriers subject to the Securities and Exchange Commission's reporting requirements, the minimum number of

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

PBRSUs that will vest, as of the vesting date, will be equal to the grant amount times 50 percent. If the Company's relative Adjusted ROIC ranks highest compared to the Company's Peer Group, the minimum number of PBRSUs that will vest, as of the vesting date, will be equal to the grant amount times 100 percent.

Under the 2025 grants, the number of PBRSUs vesting on the vesting date will be interpolated based on the Company's Adjusted ROIC performance, as defined, and ranges from zero to 200 percent of granted PBRSUs, only after a minimum performance level has been achieved. Adjusted ROIC for the Performance Period is the average of the ROIC, using an assumed federal tax rate of 23.5 percent, over the three full fiscal years within the Performance Period (2025, 2026, and 2027), and vesting is also subject generally to the individual's continued employment or service. However, in the event the Company's average Adjusted ROIC is greater than zero and exceeds the median (i.e., 50th percentile) return on invested capital of certain of the Company's Peer Group of domestic mainline carriers subject to the Securities and Exchange Commission's reporting requirements, the minimum number of PBRSUs that will vest, as of the vesting date, will be equal to the grant amount times 50 percent. If the Company's relative Adjusted ROIC ranks highest compared to the Company's Peer Group, the minimum number of PBRSUs that will vest, as of the vesting date, will be equal to the grant amount times 100 percent.

Under the 2025 Southwest Even Better ("SEB") grants, the number of PBRSUs vesting on the vesting date will be based on the Company's Adjusted EBIT (as defined) for the years 2026 and 2027 and ranges from zero percent of granted PBRSUs to 200 percent of granted PBRSUs, only after a minimum performance level has been achieved. Vesting is also subject generally to the individual's continued employment.

With respect to PBRSUs granted in 2023, 2024, and 2025, not including the SEB grants, provided that the individual's service has terminated no earlier than 12 months after the date of grant, in the event of a "qualified retirement," such individual's PBRSUs will remain outstanding as if the individual's service has not terminated and will otherwise be settleable in accordance with the notice of grant and applicable terms and conditions; however, the number of shares received upon settlement will be prorated based on the individual's number of days of service between the date of grant and the end of the performance period.

For all RSU and PBRSU grants, forfeiture rates are estimated at the time of grant based on historical actuals for similar grants, and are trued-up to actuals over the vesting period. For all RSU and PBRSU grants, the Company recognizes all expense on a straight-line basis over the vesting period, as adjusted for qualified retirement provisions, with any changes in expense due to the number of RSUs and PBRSUs expected to vest being modified on a prospective basis.

***Taxes***

Grants of RSUs result in the creation of a deferred tax asset, which is a temporary difference, until the time the RSU vests. All excess tax benefits and tax deficiencies are recorded through the Consolidated Statement of Income. Due to the treatment of RSUs for tax purposes, the Company's effective tax rate from year to year is subject to variability.

**10. FINANCIAL DERIVATIVE INSTRUMENTS**

***Fuel Contracts***

&nbsp;&nbsp;&nbsp;&nbsp;

Airline operators are inherently dependent upon energy to operate and, therefore, are impacted by changes in jet fuel prices. Furthermore, jet fuel and oil typically represents one of the largest operating expenses for airlines. The Company has historically aimed to reduce volatility in operating expenses through its fuel hedging program. However, based on higher fuel hedging premium costs over time and other factors, the Company has discontinued its fuel hedging program in 2025 and does not intend to add additional fuel derivatives at this time.

For the purpose of evaluating its net cash spend for jet fuel and for forecasting its future estimated jet fuel expense, the Company has historically evaluated its hedge volumes strictly from an "economic" standpoint and thus did not consider whether the hedges had qualified or would qualify for hedge accounting. The Company defined its "economic" hedge as the net volume of fuel derivative contracts held, including the impact of positions that were offset through sold positions, regardless of whether those contracts qualified for hedge accounting.

During second quarter 2025, the Company terminated its remaining portfolio of fuel hedging contracts, which were scheduled to settle through 2027, to effectively close its fuel hedging portfolio and program. This resulted in the derecognition of all remaining related hedge assets in the Consolidated Balance Sheet. The cash proceeds from this transaction totaled approximately $40 million, which will reduce future premium costs. Subsequent to this termination, approximately $96 million that was previously expended on hedge positions in prior periods was reclassified from AOCI and recognized as an increase to Fuel and oil expense within the Consolidated Statement of Income during 2025, all of which is characterized as premium expense from terminated fuel hedging positions. As of December 31, 2025, approximately $137 million remained in AOCI related to these closed positions. This balance in AOCI, which does not include any tax impact, will also be characterized as premium expense and similarly reclassified as an increase to Fuel and oil expense in future periods when the originally forecasted transactions occur (through the end of 2027), and is net of the impact of the cash proceeds from the hedge terminations. See Note 12 for additional information on AOCI.

Historically, upon proper qualification, the Company accounted for its fuel derivative instruments as cash flow hedges. Qualification was re-evaluated quarterly, and all periodic changes in fair value of the derivatives designated as hedges were recorded in AOCI until the underlying jet fuel was consumed. See Note 12.

If a derivative initially did not qualify or ceased to qualify for hedge accounting, any change in the fair value of derivative instruments since the last reporting period was recorded in Other (gains) losses, net in the Consolidated Statement of Income in the period of the change; however, any amounts previously recorded to AOCI remained there until such time as the original forecasted transaction occurred, at which time these amounts were reclassified to Fuel and oil expense.

During third quarter 2024, the routine statistical analysis performed by the Company to determine which commodities qualify for special hedge accounting treatment on a prospective basis indicated that WTI crude oil-based derivatives no longer qualified for hedge accounting. This change was primarily due to the fact that the correlation between WTI crude oil prices and jet fuel prices during recent periods had not been as strong as in the past, and therefore the Company could no longer demonstrate that derivatives based on WTI crude oil prices would result in effective hedges on a prospective basis. As such, all WTI-based instruments were de-designated from their hedging relationships and the change in fair value of all of the Company's derivatives based in WTI was recorded to Other (gains) losses for third and fourth quarter 2024. All WTI crude oil based derivatives in the Company's portfolio have settled as of December 31, 2024. The change in fair value of the Company's WTI derivative contracts during the second half of 2024 was a decrease of $37 million, which resulted in a corresponding loss in the Consolidated Statement of Income. Any amounts previously recorded to AOCI remained there until the original forecasted transaction occurred in accordance with hedge accounting requirements.

All of the Company's prior period fuel derivative instruments and current period interest rate swaps are subject to agreements that follow the netting guidance in the applicable accounting standards for derivatives and hedging. The types of derivative instruments the Company determined were subject to netting requirements in the accompanying Consolidated Balance Sheet are those in which the Company paid or received cash for transactions with the same counterparty and in the same currency via one net payment or receipt. For cash collateral held by the Company or provided to counterparties, the Company netted such amounts against the fair value of the Company's derivative portfolio by each counterparty. The Company elected to utilize netting for its prior period fuel derivative instruments and also classified such amounts as either current or noncurrent, based on the net fair value position with each of the Company's counterparties in the Consolidated Balance Sheet.

The Company had the following recognized financial assets and financial liabilities resulting from those transactions that meet the scope of the disclosure requirements as necessitated by applicable accounting guidance for balance sheet offsetting:

***Interest Rate Derivatives***

The Company is at times party to certain interest rate swap agreements that are accounted for as either fair value hedges or cash flow hedges, as defined in the applicable accounting guidance for derivative instruments and hedging. The Company did not have any interest rate swap agreements designated as cash flow hedges during the periods presented. During the periods presented, the Company's interest rate swap agreements qualify for the "shortcut" or "critical terms match" methods of accounting for hedges, which dictate that the hedges were assumed to be perfectly effective at origination and, thus, there was no ineffectiveness to be recorded in the Consolidated Statement of Income.

During fourth quarter 2025, the Company entered into interest rate swap agreements as a hedge related to its $750 million 5.25% Notes due 2035. See Note 6. The primary objective for the Company's use of this interest rate hedge was to hedge against changes in the fair value of the debt instrument caused by changes in market interest rates, specifically SOFR. The hedge strategy is to eliminate the changes in fair value of the debt by converting the fixed rate interest of the debt to a floating rate. Under these interest rate swap agreements, the Company pays SOFR plus a margin every six months on the notional amount of the debt, and receives payments based on the fixed stated rate of the notes every six months until the date the notes become due. These interest rate swap agreements collectively qualify as a fair value hedge. As a result of the fixed-to-floating interest rate swap agreements in place, the average floating rate recognized during 2025 was approximately 5.44 percent, based on actual and forward rates as of December 31, 2025.

The fair values of the interest rate swap agreements, which are adjusted regularly, have been aggregated by counterparty for classification in the Consolidated Balance Sheet. Agreements totaling a net liability of $16 million, are fair value hedges, and are classified as components of Other noncurrent liabilities. The corresponding offsetting adjustment related to the net asset (or liability) associated with the Company's fair value hedges is to Long-term debt less current maturities.

During fourth quarter 2023, the Company terminated $150 million notional value of forward-starting interest rate swap agreements associated with the Company's forecasted issuance of debt. These swap agreements had been classified as cash flow hedges, and all fair market value changes were recorded to AOCI prior to their termination. Following the issuance of the Company's $750 million 5.25% Notes due 2035 in fourth quarter 2025, the deferred gain of $23 million associated with these terminated swaps is now being amortized to Interest expense over the life of the notes.

***Credit Risk and Collateral***

The Company had no cash collateral posted or received as of December 31, 2025.

**11. FAIR VALUE MEASUREMENTS**

Accounting standards pertaining to fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

As of December 31, 2025, the Company held certain items that are required to be measured at fair value on a recurring basis. These consisted of cash equivalents, but at other times the Company also holds short-term investments and available-for-sale securities. The majority of the Company's cash equivalents and short-term investments consist of instruments classified as Level 1. However, when the Company holds certificates of deposit and time deposits, they are classified as Level 2, due to the fact that the fair value for these instruments is determined utilizing observable inputs in non-active markets. Equity securities primarily consist of investments with readily determinable market values associated with the Company's excess benefit plan and market-based cash balance plan.

During second quarter 2025, the Company terminated its remaining portfolio of fuel hedging contracts, which were scheduled to settle through 2027, to effectively close its fuel hedging portfolio and program. The Company's interest rate derivative instruments and prior period fuel derivative instruments consist of over-the-counter contracts, which are not traded on a public exchange. Fuel derivative instruments historically consisted solely of option contracts, whereas interest rate derivatives consist solely of swap agreements. See Note 10 for further information on the Company's derivative instruments and hedging activities. The fair values of swap contracts are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. Therefore, the Company has categorized these swap contracts as Level 2. In prior periods, the Company determined the value of option contracts utilizing an option pricing model based on inputs that are either readily available in public markets, can be derived from information available in publicly quoted markets, or are provided by financial institutions that trade these contracts. The option pricing model used by the Company is an industry standard model for valuing options and is a similar model used by the broker/dealer community (i.e., the Company's counterparties). The inputs to this option pricing model are the option strike price, underlying price, risk free rate of interest, time to expiration, and volatility. Because certain inputs used to determine the fair value of option contracts are unobservable (principally implied volatility), the Company categorized these option contracts as Level 3. Volatility information was obtained from external sources, but was analyzed by the Company for reasonableness and compared to similar information received from other external sources. Holding other inputs constant, an increase (decrease) in implied volatility would have resulted in a higher (lower) fair value measurement, respectively, for the Company's derivative option contracts. The fair value of option contracts considered both the intrinsic value and any remaining time value associated with those derivatives that had not yet settled. The Company also considered counterparty credit risk and its own credit risk in its determination of all estimated fair values. To validate the reasonableness of the Company's option pricing model, on a monthly basis, the Company compared its option valuations to third party valuations. However, no significant differences were noted. The Company has consistently applied these valuation techniques in prior periods presented and believes it obtained the most accurate information available for the types of derivative contracts it previously held.

Included in Equity securities are the Company's investments primarily associated with its deferred compensation plans, which consist of mutual funds that are publicly traded and for which market prices are readily available. These plans are non-qualified deferred compensation plans designed to hold contributions in excess of limits established by the Internal Revenue Code of 1986, as amended. The distribution timing and payment amounts under these plans are made based on the participant's distribution election and plan balance. Assets related to the funded portions of the deferred compensation plans are held in a rabbi trust, and the Company remains liable to these participants for the unfunded portion of the plans. The Company records changes in the fair value of plan obligations and plan assets, which net to zero, within the Salaries, wages, and benefits line and Other (gains) losses, net line, respectively, of the Consolidated Statement of Income.

The fair values of the Company's publicly held debt are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets; therefore, the Company has categorized these agreements as Level 2. All privately held debt agreements are categorized as Level 3. The Company has determined the estimated fair value of this debt to be Level 3, as certain inputs used to determine the fair value of these agreements are unobservable. The Company utilizes indicative pricing from counterparties and a discounted cash flow method to estimate the fair value of the Level 3 items.

**13. EMPLOYEE RETIREMENT PLANS**

***Defined Contribution Plans***

The Company has defined contribution plans covering substantially all Employees. Contributions to these plans are primarily based on Employee elective deferrals as well as their eligible compensation and Company performance. The Company sponsors Employee savings plans under section 401(k) of the Internal Revenue Code of 1986, as amended. The Southwest Airlines Pilots Retirement Saving Plan has non-elective Company contributions. In the Southwest Airlines Co. Retirement Savings Plan (the "Retirement Savings Plan"), non-elective contributions are allowed for certain eligible workgroups that have negotiated such items as part of ratified collective-bargaining

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

contracts, Company matching contributions are made for eligible Employees contributing to their 401(k) accounts, and the Company contributes a percentage of its annual net profits, as defined.

Amounts associated with the Company's defined contribution plans expensed in 2025, 2024, and 2023, reflected as a component of Salaries, wages, and benefits, were $1.0 billion, $825 million, and $941 million respectively.

***Defined Benefit Plan***

In 2024, the Company began offering a market based cash balance defined benefit plan covering eligible Pilots. The Company's funding obligation for the qualified plan is governed by the Employee Retirement Income Security Act of 1974 (ERISA) and any applicable regulations. The plan provides pension credits equal to 1 percent of eligible wages for qualifying participants, which are credited based on in a designated portfolio of equity and fixed income assets. For payroll periods ending on or after January 1, 2026, each pension credit shall be equal to 2 percent of eligible wages for qualifying participants. Participants' hypothetical account balances reflect interest credits, calculated monthly based on the actual returns (positive or negative) of the designated portfolio. Participants' benefits consist of the sum of the pension credits and the returns (or losses) accrued on the hypothetical invested contributions. Amounts exceeding the limits established under the Internal Revenue Code will be provided through a separate unfunded arrangement or paid in cash. As a defined benefit plan, participants are guaranteed a distribution equivalent to no less than the sum of the original pension credits. For married participants, the default form of payment is a 50 percent qualified joint and survivor annuity payable over the joint lives of the participant and spouse unless the spouse consents to an alternative form. For unmarried participants, the default form is a single life annuity. Other annuity forms may be available as described in the plan document.

***Postretirement Benefit Plans***

The Company provides postretirement benefits to qualified retirees in the form of medical and dental coverage. Employees must meet minimum levels of service and age requirements as set forth by the Company, or as specified in collective-bargaining agreements with specific workgroups. Employees meeting these requirements, as defined, may use accrued unused sick time to pay for medical and dental premiums from the age of retirement until age 65.

The following table shows the change in the accumulated market based cash balance plan and postretirement benefit obligations for the years ended December 31, 2025 and 2024:

During 2025, the Company recorded $59 million in combined actuarial losses as an increase to the market based cash balance and postretirement benefit plans with an offset to AOCI. These 2025 actuarial losses are reflected

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

above and resulted from changes in certain key assumptions used to determine the Company's year-end obligation. The assumption change that resulted in the largest portion of the actuarial loss was a decrease in the discount rate used.

Benefits earned under the market based cash balance plan are expected to be paid from funded benefit plan assets, while the postretirement benefits are funded from current assets. The following table shows the estimated future benefit payments expected to be paid:

| Amortization of net gain |  |  | (7) | (7) | (10) |
| Net periodic benefit cost | $32 | $31 | $23 | $23 | $16 |

---

Service cost is recognized within Salaries, wages, and benefits expense, and all other costs are recognized in Other (gains) losses, net in the Consolidated Statement of Income. Unrecognized prior service cost is expensed using a straight-line amortization of the cost over the average future service of Employees expected to receive benefits under the plans. Actuarial gains are amortized utilizing the minimum amortization method. The following actuarial assumptions were used to account for the Company's market based cash balance and postretirement plans at December 31, 2025, 2024, and 2023:

The selection of a discount rate is made annually and is selected by the Company based upon comparison of the expected future cash flows associated with the Company's future payments under its consolidated benefit obligations to a yield curve created using high quality bonds that closely match those expected future cash flows.

This rate for postretirement benefits decreased during 2025 due to market conditions. The assumed healthcare trend rate is also reviewed at least annually and is determined based upon both historical experience with the Company's benefits paid and expectations of how those trends may or may not change in future years.

The expected long-term rate of return on plan assets is based on historical market and volatility data and expected market conditions, reflecting a target asset allocation of 40 percent equities and 60 percent fixed income. The Company reviews the rate of return on plan assets assumption annually. The annual investment performance for one particular year does not, by itself, significantly influence the Company's evaluation.

**14. INCOME TAXES**

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The components of deferred tax assets and liabilities as of December 31, 2025 and 2024, are as follows:

---

| | | |
|:---|:---|:---|
| **(in millions)** | **2025** | **2024** |
| **DEFERRED TAX LIABILITIES:** |  |  |
| &nbsp;&nbsp;&nbsp;Accelerated depreciation | $3655 | $3351 |
| &nbsp;&nbsp;&nbsp;Prepaid insurance | 329 | 282 |
| &nbsp;&nbsp;&nbsp;Operating lease right-of-use assets | 249 | 314 |
| &nbsp;&nbsp;&nbsp;Other | 99 | 99 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total deferred tax liabilities | 4332 | 4046 |
| **DEFERRED TAX ASSETS:** |  |  |
| &nbsp;&nbsp;&nbsp;Accrued employee benefits | 356 | 337 |
| &nbsp;&nbsp;&nbsp;Loyalty program and flight credit liability | 540 | 604 |
| &nbsp;&nbsp;&nbsp;Operating lease liabilities | 252 | 319 |
| &nbsp;&nbsp;&nbsp;Net operating losses and tax credits (a) | 644 | 352 |
| &nbsp;&nbsp;&nbsp;Other | 260 | 267 |
| &nbsp;&nbsp;&nbsp;Valuation allowance | (9) |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total deferred tax assets | 2043 | 1879 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Net deferred tax liability | $2289 | $2167 |

---

(a) As of December 31, 2025 and 2024, the Company had approximately $66 million and $56 million, respectively, of state net operating loss carryforwards (tax effected) to reduce future state taxable income. These state net operating loss carryforwards will expire in years 2026 through 2046 if unused. As of December 31, 2025 and 2024, the Company had $504 million and $253 million, respectively, of federal net operating loss carryforwards (tax effected) that may be carried forward indefinitely. As of December 31, 2025 and 2024, the Company had $75 million and $53 million, respectively, of federal research and development tax credit carryforwards subject to expiration beginning in 2043 if unused.

A valuation allowance is recorded when it is more likely than not that some portion of deferred tax assets will not be realized. During 2025, the Company established deferred tax assets related to Texas research and development tax credits. The gross deferred tax asset totaled $13 million, of which approximately $12 million is not expected to be realized based on current projections of taxable income and applicable utilization limitations. Accordingly, as of December 31, 2025, the Company recorded a valuation allowance of approximately $12 million against these assets. The change in the valuation allowance during the year reflects the initial recognition of the deferred tax assets and updated assessments of future utilization.

Foreign pretax income, income tax expense, and income taxes paid were immaterial for all periods presented. As a result, foreign amounts have not been separately disaggregated.

The provision (benefit) for income taxes is composed of the following:

---

| | | | |
|:---|:---|:---|:---|

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total deferred | 122 | 132 | 159 |

| &nbsp;&nbsp;&nbsp;&nbsp;Total income tax provision | $122 | 21.7% | $133 | 22.2% | $168 | 26.5% |

---

(1) State taxes in California, New York City, and Hawaii for 2023; California, Texas, and Hawaii for 2024; and Florida, Maryland, California, Colorado, and Arizona for 2025 represented the majority (greater than 50%) of the tax effect within this category.

The total cash paid for income taxes (net of refunds) is composed of the following:

---

| | | | |
|:---|:---|:---|:---|
| **(in millions)** | **2025** | **2024** | **2023** |
| U.S. federal | $(2) | $(19) | $(96) |
| State\* | 1 | (2) | 9 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total cash paid for income taxes (net of refunds) | $(1) | $(21) | $(87) |

---

\* Some jurisdictions met the 5% disaggregation threshold; however, the related amounts were immaterial.

The amount of, and changes to, the Company's uncertain tax positions were not material in any of the periods presented. Additionally, the Company does not expect significant changes to the total amount of unrecognized tax benefits within the next 12 months.

The only periods subject to examination for the Company's federal tax return are tax years 2020, 2024, and 2025. The Company is also subject to various examinations from state and local income tax jurisdictions in the ordinary course of business. These examinations are not expected to have a material effect on the financial results of the Company.

***Other Operating Expenses***

Other operating expenses consist of aircraft rentals, distribution costs, advertising expenses, personnel expenses, professional fees, certain technology-related costs, and other operating costs, none of which individually exceeded 10 percent of Total operating expenses.

**16. RESTRUCTURING**

In February 2025, the Company implemented a reduction in its workforce designed to reduce operating costs, increase efficiency, and create a leaner and more agile organization as part of its transformational plan. The workforce reduction of approximately 1,750 Employee roles was focused almost entirely on corporate overhead and leadership positions and represented approximately 15 percent of corporate positions, including senior leadership. Separations were substantially completed by the end of second quarter 2025.

As a result of this workforce reduction, the Company recorded a one-time expense of $62 million in first quarter 2025, which is included on the Consolidated Statement of Income as part of Salaries, wages, and benefits and Other operating expenses. Substantially all of the expense is due to Employee severance payments and related professional fees and was substantially paid in first and second quarter 2025, with no amounts remaining on the Consolidated Balance Sheet as of December 31, 2025. The Company does not expect to incur any material additional costs in connection with this reduction in workforce.

**Report of Independent Registered Public Accounting Firm**

To the Shareholders and the Board of Directors of Southwest Airlines Co.

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of Southwest Airlines Co. (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 5, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical audit matter**

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

| | ***Valuation of co-brand marketing component*** |
| *Description of the Matter* | As described in Note 5 to the consolidated financial statements, the Company executed an amendment to its co-branded credit card agreement ("Agreement") with Chase Bank USA, N.A. ("Chase") in June 2025, through which the Company sells Chase loyalty points, the use of its brand and access to its Rapid Rewards Member lists ("the marketing component"), and certain ancillary benefits for Chase cardholders. The Company estimated the selling prices over the term of the Agreement to determine the allocation of proceeds to the identified performance obligations. The Company estimated the standalone selling price of each of the performance obligations to determine the allocation of proceeds to each of the performance obligations based upon their relative selling prices. The Company applies the relative selling price allocation to the performance obligations in each period through the term of the arrangement. <br>Auditing the valuation of the marketing component of the co-brand agreement with Chase was complex and highly judgmental due to the absence of observable standalone selling prices. A change in the estimated selling price of the marketing component could have a material impact on the timing of revenue recognition. |
| *How We Addressed the Matter in Our Audit* | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's determination of the estimated standalone selling price of the marketing component and the completeness and accuracy of the data underlying the estimate.<br>To test the estimated selling price of the marketing component, our audit procedures included, among others, involving a valuation specialist to assist in testing the methodology used to develop the estimated standalone selling price of the marketing component and assessing the reasonableness of the royalty rate used to develop the estimate. Additionally, we assessed the sensitivity of the Company's recognized revenue to changes in the inputs used to estimate the standalone selling price of the marketing component. |

**Report of Independent Registered Public Accounting Firm**

To the Shareholders and the Board of Directors of Southwest Airlines Co.

**Opinion on Internal Control Over Financial Reporting**

We have audited Southwest Airlines Co.'s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework), (the COSO criteria). In our opinion, Southwest Airlines Co. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and our report dated February 5, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion**

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting**

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

------

<u>[Notes to Consolidated Financial Statements](#id4b63aa117ff4ef0ac41217a4f4b5530_118)</u>

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**Item 9.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*Changes in and Disagreements With Accountants on Accounting and Financial Disclosure***

None.

**Item 9A.&nbsp;&nbsp;&nbsp;&nbsp;*Controls and Procedures***

*Evaluation of Disclosure Controls and Procedures.* The Company maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act (the "Exchange Act")) designed to provide reasonable assurance that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms. These include controls and procedures designed to ensure that this information is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company's disclosure controls and procedures as of December 31, 2025. Based on this evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that the Company's disclosure controls and procedures were effective as of December 31, 2025, at the reasonable assurance level.

*Management's Annual Report on Internal Control over Financial Reporting.* Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act). The Company's internal control over financial reporting is a process, under the supervision of the Company's Chief Executive Officer and Chief Financial Officer, designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance of achieving their control objectives.

Management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company's internal control over financial reporting as of December 31, 2025. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework (2013 Framework). Based on this evaluation, management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, concluded that, as of December 31, 2025, the Company's internal control over financial reporting was effective.

Ernst & Young LLP, the independent registered public accounting firm who audited the Company's Consolidated Financial Statements included in this Form 10-K, has issued an attestation report on the Company's internal control over financial reporting, which is included herein.

*Changes in Internal Control over Financial Reporting.* There were no changes in the Company's internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the quarter ended December 31, 2025, that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

## Exhibit 4.6

![](exhibit46-descriptionofc001.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;Exhibit 4.6 DESCRIPTION OF COMMON STOCK General Southwest Airlines Co. (the "Company," "we," or "our") is incorporated in the State of Texas. The rights of our shareholders are generally covered by Texas law and our certificate of formation and bylaws (each as amended and restated and in effect on the date hereof). The terms of our common stock are therefore subject to Texas law, including the Texas Business Organizations Code (the "TBOC"), and the common and constitutional law of Texas. This exhibit describes the general terms of our common stock. This is a summary and does not purport to be complete. Our certificate of formation and bylaws as they exist on the date of this Annual Report on Form 10-K are incorporated by reference or filed as an exhibit to the Annual Report on Form 10-K of which this exhibit is a part, and amendments or restatements of each will be filed with the Securities and Exchange Commission (the "SEC") in future periodic or current reports in accordance with the rules of the SEC. You are encouraged to read these documents. For more detailed information about the rights of our common stock, you should refer to our certificate of formation and bylaws and the applicable provisions of Texas law, including the TBOC, for additional information. Authorized Capital Stock We are authorized to issue 2,000,000,000 shares of common stock, $1.00 par value. We are not authorized to issue shares of preferred stock. Voting Rights Holders of our common stock are entitled to one vote per share in the election of directors and on all other matters submitted to a vote at a meeting of shareholders. No shareholder has the right of cumulative voting. With respect to any matter other than the election of directors or a matter for which the affirmative vote of the holders of a specified portion of the shares entitled to vote is required by Texas law or our certificate of formation, the act of the shareholders shall be the affirmative vote of the holders of a majority of the shares entitled to vote on, and voted for or against, the matter at a meeting of shareholders at which a quorum is present; provided that, for purposes thereof, all abstentions and broker nonvotes shall not be counted as voted either for or against such matter. Directors shall be elected by a majority of the votes cast by the holders of shares entitled to vote in the election of directors at a meeting of shareholders at which a quorum is present; provided that, if the number of nominees exceeds the number of directors to be elected, directors shall be elected by a plurality of the votes cast. For purposes thereof, (i) a majority of the votes cast means that the number of votes cast for a director must exceed the number of votes cast against that director, and (ii) abstentions and broker nonvotes shall not be counted as votes cast either for or against any nominee for director. Directors may be removed with or without cause, by vote of the holders of a majority of the shares then entitled to vote for the election of directors. Dividend Rights

------

![](exhibit46-descriptionofc002.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Holders of our common stock are entitled to dividends when, as, and if declared by our board of directors out of funds legally available therefor. Liquidation Rights In the event of our liquidation, the holders of our common stock will be entitled to share ratably in any assets remaining after payment of all debts and other liabilities. Certain Business Combination Restrictions Section 21.606 of the TBOC restricts certain business combinations between us and an affiliated shareholder (beneficial ownership of 20% or more of the voting power of our stock entitled to vote for directors) for three years after the shareholder becomes an affiliated shareholder. The restrictions do not apply if the board of directors approved the transaction that caused the shareholder to become an affiliated shareholder or if the business combination is approved by the affirmative vote of two-thirds of our voting stock that is not beneficially owned by the affiliated shareholder at a meeting of shareholders called for that purpose within six months of the affiliated shareholder's acquiring the shares. Although we may elect to exclude ourselves from the restrictions imposed by Section 21.606, our certificate of formation does not do so. Certain Provisions of Our Certificate of Formation and Bylaws Advance Notice for Shareholder Proposals and Director Nominations Our bylaws establish advance notice procedures with regard to shareholder proposals to be included in the Company's proxy statements, shareholder nominations of directors to be included in the Company's proxy statements, shareholder nominations of directors and other proposals of business to be presented at an annual meeting of shareholders but not included in the Company's proxy statements, and shareholder proxy solicitations for shareholder director nominees. Generally, the advance notice provisions require that shareholder proposals to be included in the Company's proxy statement be provided to us not less than 120 days before the release date of the Company's proxy statement in connection with the last annual meeting, director nominations be provided to us between 120 and 150 days before the anniversary of our last annual meeting, and shareholder proposals to be presented at the annual meeting but not included in the Company's proxy statement be provided to us between 60 and 90 days before the anniversary of our last annual meeting in order to be properly brought before a shareholder meeting. The notice must set forth specific information regarding that shareholder and that business or director nominee, as described in our bylaws. This requirement is in addition to those set forth in the rules and regulations adopted by the SEC under the Securities Exchange Act of 1934. Proxy Access Our bylaws permit a shareholder, or a group of up to 20 shareholders (with funds having specified relationships constituting a single shareholder), owning three percent or more of our outstanding common stock continuously for at least three years, to nominate and include in our proxy materials director candidates constituting up to 20 percent of our board of directors (rounded down to the nearest whole number) or two directors, whichever is greater, provided that the shareholder(s) and the nominee(s) satisfy the requirements specified in our bylaws.

------

![](exhibit46-descriptionofc003.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Special Meetings of Shareholders Our bylaws provide that special meetings of shareholders may be called by the chair of the board of directors, the president, or the chief executive officer and shall be called by the secretary upon written request, stating the purpose or purposes therefor, by (i) a majority of the whole board of directors or (ii) one or more shareholders of record that, at the time a request is delivered, collectively own at least 10% (or such greater percentage not exceeding a majority as may be specified in our certificate of formation from time to time) of all of the shares entitled to vote at the proposed special meeting. The request for a special meeting must set forth specific information regarding the business to be conducted at the special meeting, as described in our bylaws. No Shareholder Action by Written Consent Our bylaws provide that shareholders may not act by written consent in lieu of a meeting. Exclusive Forum for Adjudication of Disputes Our bylaws provide that unless we consent in writing to the selection of an alternative forum, the United States District Court for the Northern District of Texas or, if such court lacks jurisdiction, the Texas Business Court located in Dallas County, Texas, shall, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company; (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to the Company or the Company's shareholders; (iii) any action asserting a claim against the Company or any director, officer, or other employee of the Company pursuant to any provision of our certificate of formation or our bylaws or the TBOC; and (iv) any other action asserting a claim against the Company or any director, officer, or other employee of the Company constituting an "internal entity claim" under the TBOC. Our bylaws provide that each shareholder irrevocably and unconditionally waives any right it may have to a trial by jury in any legal action, proceeding, cause of action or counterclaim concerning any internal entity claim and, to the fullest extent permitted by applicable law, in any other claim, action or proceeding against the Company or any director, officer, or other employee of the Company. Our bylaws further provide that unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States shall be the sole and exclusive forum for the resolution of complaints asserting a cause of action under the Securities Act of 1933. Derivative Proceedings Our bylaws provide that no shareholder may institute or maintain a derivative proceeding unless that shareholder is a Shareholder (as defined in Section 21.551(2) of the TBOC) that beneficially owns at least three (3) percent of the outstanding shares of the Company. Potential Anti-Takeover Effect Some provisions of our certificate of formation and bylaws could make the acquisition of control of our Company and/or the removal of our existing management more difficult, including those that provide as follows:

------

![](exhibit46-descriptionofc004.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cumulative voting in the election of our board of directors, which would otherwise allow less than a majority of shareholders to elect director candidates, is prohibited under our certificate of formation; • our board of directors fixes the size of the board of directors, may create new directorships, and may appoint new directors to serve in such newly created positions until the next election of one or more directors by our shareholders; • our board of directors may amend or repeal our bylaws, or adopt new bylaws, unless (a) such power is reserved exclusively to our shareholders in whole or part by our certificate of formation or the laws of Texas or (b) our shareholders in amending, repealing, or adopting a particular bylaw have expressly provided that our board of directors may not amend or repeal that bylaw; • all shareholder actions must be taken at a regular or special meeting of our shareholders and cannot be taken by written consent without a meeting; • we have advance notice procedures with respect to shareholder proposals and the nomination of candidates for election as directors; • our directors may be removed with or without cause, by vote of the holders of a majority of the shares then entitled to vote for the election of directors; and • unless we consent in writing to the selection of an alternative forum, (a) the United States District Court for the Northern District of Texas or, if such court lacks jurisdiction, the state district court of Dallas County, Texas, shall, to the fullest extent permitted by applicable law, be the sole and exclusive forum for certain types of actions or proceedings and (b) the federal district courts shall be the sole and exclusive forum for causes of action under the Securities Act. These provisions are expected to discourage coercive takeover practices and inadequate takeover bids. They are also designed, in part, to encourage persons seeking to acquire control of the Company to first negotiate with our board of directors. We believe that the benefits of increased protection give us the potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us and that these benefits outweigh the disadvantages of discouraging the proposals. Negotiating with the proponent could result in an improvement of the terms of the proposal. Other Our common stock has no preemptive or conversion rights and is not entitled to the benefits of any redemption or sinking fund provision. The outstanding shares of our common stock are fully paid and non-assessable. Stock Exchange Listing Our common stock is traded on the New York Stock Exchange under the symbol "LUV."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1 SOUTHWEST AIRLINES CO. AMENDED AND RESTATED 2007 EQUITY INCENTIVE PLAN TERMS AND CONDITIONS PERFORMANCE-BASED RESTRICTED STOCK UNITS (For Southwest Even Better Award) By asserting any rights with respect to performance-based Restricted Stock Units ("PBRSUs" or "Performance-Based Restricted Stock Units") received pursuant to the Southwest Airlines Co. Amended and Restated 2007 Equity Incentive Plan (the "Plan"), the recipient of the PBRSUs (the "Participant") will be deemed to have understood and agreed to the terms and conditions of the Plan and the terms and conditions set forth below. Capitalized terms used and not otherwise defined in these Terms and Conditions shall have the meanings assigned to them in the Plan or in the Notice of Grant of Performance-Based Restricted Stock Units with which these Terms and Conditions are enclosed (the "Notice of Grant"). 1. Vesting. Subject to these Terms and Conditions and the provisions of the Plan, vesting of the PBRSUs will be subject to and in accordance with the schedule set forth in the Notice of Grant. 2. Interpretation. The Participant's Performance-Based Restricted Stock Unit Award is subject to the terms and conditions of the Plan, which terms and conditions are incorporated herein by reference. The Participant's Performance-Based Restricted Stock Unit Award is also subject to any rules promulgated pursuant to the Plan by the Board, the Committee, or the persons designated by the Committee to administer the day-to-day administration of the Plan. Any decisions or interpretations upon any questions with respect to a Performance-Based Restricted Stock Unit Award or the Plan, including the determination of the number of shares of Common Stock to be received upon settlement of the Participant's Performance-Based Restricted Stock Units, shall (as permissible pursuant to applicable laws, rules, or regulations, including the rules of any stock exchange upon which the Company's Common Stock is listed or quoted) be determined (i) by the Committee, (ii) by the Board, or (iii) where permitted by the Committee, by any person(s) to whom the Committee has delegated its authority. The Participant (and any person who has acquired the PBRSUs by will or the laws of descent and distribution or intestacy) agrees to accept any such decisions or interpretations as binding, conclusive, and final in all respects. 3. Settlement of Performance-Based Restricted Stock Units. Subject to these Terms and Conditions and the provisions of the Plan, on the Vesting Date, the Participant (or any person who has acquired the PBRSUs by will or the laws of descent and distribution or intestacy) will become entitled to delivery of one share of Common Stock for each Performance-Based Restricted Stock Unit that vests, as determined in accordance with the schedule set forth in the Notice of Grant (the "Vested Shares"). As soon as is administratively and reasonably practicable after the Vesting Date (but in any event, no later than 30 days thereafter), such Vested Shares will be registered in the Participant's name or otherwise delivered or credited for the Participant's account or benefit (in each case as determined by the Company), subject to (a) the Participant's satisfaction of any Tax Obligations (as defined in Section 5 below); (b) the Participant's taking of any additional action deemed necessary or advisable by the Company to enable it to accomplish the delivery of the shares of Common Stock; and (c) the condition precedent that, if at any time the Board or the Committee shall determine in their discretion that the listing, registration, or qualification of the Vested Shares is required under any federal, state, or other law, rule, or regulation, or by the requirements of any securities exchange, or that the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the issuance of the Vested Shares, then the PBRSUs will not vest in whole or in part unless and until such listing, registration, qualification, consent, or approval shall have been effected or obtained free of any conditions not acceptable to the Board or the Committee; provided, however, in the event any action required by clause (a) or (b) above has not been completed by the Participant within 85 days following the Vesting Date, such Performance-Based Restricted

------

![](exhibit1014-formof2025so004.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2 Stock Units will be forfeited at 4:00 p.m., Eastern Time, on such date. No fractional shares of Common Stock will be issued in settlement of the PBRSUs. 4. Rights Upon Termination of Service. In the event of termination of the Participant's Service prior to the Vesting Date, all Performance-Based Restricted Stock Units shall automatically and without notice be forfeited at 4:00 p.m., Eastern Time, on the date of termination; provided that, notwithstanding anything in the Plan or the Notice of Grant to the contrary, in the event of the termination of the Participant's Service as a result of death or Disability, such Participant's Performance-Based Restricted Stock Units will remain outstanding as if the Participant's Service has not terminated and will otherwise be settleable in accordance with the Notice of Grant, these Terms and Conditions, and the terms of the Plan. 5. Taxes. a. In order to comply with any federal, state, local, or other laws or regulations of the United States or any other applicable jurisdiction, the Company or any Affiliate is authorized to take such action as it shall deem appropriate to provide that all applicable federal, state, local, or other income, employment, or other tax withholding or similar obligations (collectively, "Tax Obligations") to which the Participant is subject in connection with the PBRSUs are withheld or collected from the Participant. If and to the extent permitted by the Committee from time to time, the Company is authorized to satisfy the Tax Obligations by any one or more of the following methods: (i) by requiring the Participant to pay such amount in cash or check; (ii) by withholding a number of shares of Common Stock that would otherwise be issued with respect to the PBRSUs having a market value sufficient to meet the Tax Obligations; (iii) by instructing the Plan administrator to sell, or cause to be sold, on behalf of the Participant a number of Vested Shares having a market value equal to the amount of the Tax Obligations (plus sales commissions) to which the Participant is subject, and the Participant hereby appoints the Corporate Secretary of the Company as the Participant's attorney-in-fact, with full power of substitution and resubstitution, to execute such sale; (iv) by deducting the amount of the Tax Obligations out of any other remuneration otherwise payable by the Company to the Participant; or (v) by such other method as may be available to the Company from time to time. b. The Participant is ultimately liable and responsible for all of the Participant's Tax Obligations, regardless of any action taken by the Company in accordance with Section 5.a. The Company makes no representation or undertaking regarding the treatment of any Tax Obligation in connection with the grant, vesting, or settlement of the PBRSUs or the subsequent sale of any of the shares of Common Stock received upon settlement of any PBRSUs. The Company does not commit, and is under no obligation, to structure the Plan and its administration to reduce or eliminate a Participant's tax liability. c. The Participant agrees to release and indemnify the Company and its Affiliates from any liability or damages arising from or relating to the Participant's failure to comply with his or her Tax Obligations. 6. Restriction on Transfer. Performance-Based Restricted Stock Units and any rights with respect to the Participant's Performance-Based Restricted Stock Unit Award may not be sold, assigned, transferred, pledged, hypothecated, or otherwise disposed of by the Participant except by will or the laws of descent and distribution or intestacy, and any attempt to sell, assign, transfer, pledge, hypothecate, or otherwise dispose of the Participant's PBRSUs will be void and unenforceable against the Company or any Affiliate. 7. Rights as a Shareholder. The Participant will have no rights as a shareholder with respect to any shares of Common Stock covered by the Participant's Performance-Based Restricted Stock Units unless and until the Performance-Based Restricted Stock Units vest and are registered in

![](exhibit1014-formof2025so005.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3 the Participant's name or are otherwise delivered or credited for the Participant's account or benefit. 8. Adjustment of Number of Shares and Related Matters. The number and kind of shares of Common Stock covered by a Participant's Performance-Based Restricted Stock Unit Award shall be subject to adjustment in accordance with the terms of the Plan relating to recapitalization or reorganization. 9. Investment Representation. By accepting any shares of Common Stock issued pursuant to the Participant's Performance-Based Restricted Stock Unit Award, the Participant represents and warrants to the Company that the receipt of such shares shall be for investment and not with a view to distribution; provided that such representation and warranty shall be inoperative if, in the opinion of counsel to the Company, a proposed distribution of such shares is pursuant to an applicable effective registration statement under the Securities Act of 1933, as amended, or is, without such representation and warranty, exempt from registration under such Act. 10. Section 409A Compliance. The Plan and these Terms and Conditions are intended to comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended ("Section 409A"), including its exceptions, and shall be construed and administered in accordance with such intent. Notwithstanding any other provision of the Plan, these Terms and Conditions, or the Notice of Grant, any settlement of the PBRSUs may only occur upon an event and in a manner that complies with Section 409A or an applicable exemption. Any PBRSUs or settlement of PBRSUs that may be excluded from Section 409A as a short-term deferral shall be excluded from Section 409A to the maximum extent possible. Notwithstanding the foregoing, the Company makes no representations that the PBRSUs and any settlement of the PBRSUs comply with Section 409A, and the Company will not be liable for any portion of any taxes, penalties, interest, or other expenses that the Participant may incur because of non-compliance with Section 409A. Notwithstanding any provision of the Plan, these Terms and Conditions, or the Notice of Grant to the contrary, if the Participant is a "specified employee" within the meaning of Section 409A as of the date of the Participant's termination of Service, and the Company determines in good faith that immediate settlement of the PBRSUs would cause a violation of Section 409A, then to the extent shares are issuable upon the Participant's "separation from service" within the meaning of Section 409A and issuance (i) is subject to the provisions of Section 409A; (ii) is not otherwise excluded under Section 409A; and (iii) would otherwise occur during the first six-month period following the Participant's separation from service, such shares shall become issuable on the earlier of (1) the first business day after the date that is six months following the date of separation from service or (2) the date of the Participant's death. 11. No Right to Continued Service and other Participant Acknowledgments. Nothing herein shall be construed to confer upon the Participant any right to continue as an Employee, Director, or Advisor or to interfere with or restrict in any way the right of the Company or any Affiliate to discharge the Participant at any time (subject to any contractual rights of the Participant) for any reason whatsoever, with or without cause and with or without advance notice. Furthermore, nothing herein shall in any way be construed as imposing on the Company or any Affiliate a contractual obligation between the Company or any Affiliate and the Participant, other than with respect to the specific terms of the Participant's Performance-Based Restricted Stock Unit Award. 12. Law Governing. The Participant's Performance-Based Restricted Stock Unit Award shall be governed by, and construed in accordance with, the laws of the State of Texas, without regard to conflicts of laws principles thereof. 13. Legal Construction. In the event that any one or more of these Terms and Conditions shall be held by a Court of competent jurisdiction to be invalid, illegal, or unenforceable in any respect for any reason, the invalid, illegal, or unenforceable term or condition shall not affect any other term or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4 condition, and these Terms and Conditions shall be construed in all respects as if the invalid, illegal, or unenforceable term or condition had never been contained herein. 14. Amendments. The Plan and the PBRSUs may be amended or altered by the Board or the Committee to the extent provided in the Plan.

![](exhibit191-insidertradin001.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;SOUTHWEST AIRLINES CO. INSIDER TRADING POLICY To: All Board Members, Officers, Employees, and Consultants of Southwest Airlines Co. Date: July 31, 2025 Re: Southwest Airlines Co. Insider Trading Policy Background This policy applies to all Board members, Officers, Employees, and consultants of Southwest Airlines Co. This policy establishes rules intended to help prevent insider trading in Southwest securities and to protect Southwest's reputation for integrity and ethical conduct. In addition to civil and criminal penalties that the government may impose, your failure to comply with this policy may subject you to sanctions by Southwest, up to and including dismissal, whether or not your failure to comply with this policy results in a violation of law. Please read this policy carefully. Southwest reserves the right to amend or rescind this policy or any portion of it at any time and to adopt different policies and procedures at any time. In the event of any conflict or inconsistency between this policy and any other materials distributed by Southwest, this policy, as may be amended, shall govern. If a law conflicts with this policy, you must comply with the law. Statement of Policy No Transacting on Inside Information. You may not transact in Southwest securities, directly or indirectly through family members or other persons or entities, if you are aware of material nonpublic information relating to Southwest. This policy applies not only to you, but also to: • family members who live with you; • anyone else who lives with you; • any family members who do not live with you, but whose transactions in Southwest securities are directed by you or are subject to your influence or control (such as parents or children who consult with you before they transact in Southwest securities); and • partnerships, trusts, estates, and other entities that you control. You are responsible for the transactions of these other persons and entities and therefore should make them aware of the need to confer with you before they transact in Southwest securities. The existence of a personal financial emergency does not excuse you from compliance with this policy. You may not transact in the securities of any other publicly traded company with which Southwest does business in circumstances where you receive material nonpublic information about such other company that has been provided to Southwest and as to which Southwest has a duty of confidentiality that is known to you regarding such information.

------

![](exhibit191-insidertradin002.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;2 No Tipping. You may not communicate material nonpublic information about Southwest to any other person for use in purchasing or selling Southwest securities, and you may not make recommendations or express opinions as to transacting in Southwest securities on the basis of material nonpublic information. These practices, known as "tipping," can result in civil and criminal penalties even if you have not gained any personal financial benefit from the other person's transacting in Southwest securities. Material nonpublic information must not be communicated to anyone except as is necessary to the conduct of Southwest's business and only in accordance with Southwest's policies on confidentiality. Prohibited Transactions While in Possession of Material Nonpublic Information. The prohibition on transacting in Southwest securities while in possession of material nonpublic information relating to Southwest applies to purchases and sales of Southwest common stock, debt securities (debentures, bonds, and notes), warrants, convertible securities, and derivative securities and gifting of Southwest securities. To be clear, this prohibition on transacting applies to sales to third parties of common stock acquired under Southwest plans. For example: • Application to Restricted Stock Units and Stock Options. This policy's transacting restrictions apply to any sale of Southwest common stock acquired upon vesting of restricted stock units, exercise of stock options, or other stock-based compensation awards, including any sale that results from a cashless exercise of a stock option through a broker. • Application to Employee Stock Purchase Plan. This policy's transacting restrictions apply to any sale of common stock purchased through Southwest's employee stock purchase plan. • Application to ProfitSharing Plan. This policy's transacting restrictions apply to your Southwest common stock transactions in Southwest's ProfitSharing Plan. Permitted transactions under Southwest plans are discussed under "Permitted Transactions." Special and Prohibited Transactions. Except as discussed under "Permitted Transactions," the following transactions are prohibited. • Hedging Transactions. Hedging or monetization transactions involving Southwest securities are prohibited, whether or not you are in possession of material nonpublic information. • Short Sales. Short sales involving Southwest securities are prohibited. • Derivative Securities. Transactions in derivative securities involving Southwest securities are prohibited. This policy does not, however, restrict holding, exercising, or settling awards such as options, restricted stock, restricted stock units, or other derivative securities granted under a Southwest equity compensation plan. • Gifts. Gifting Southwest securities while in possession of material nonpublic information relating to Southwest is prohibited.

------

![](exhibit191-insidertradin003.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;3 • Standing Orders. Individuals subject to Southwest's Blackout and Pre-Clearance Procedures are prohibited from entering into standing orders. For others subject to this policy, standing orders should be used only for a maximum period of five days or such other time as designated by Southwest's Chief Legal Officer (or equivalent). • Margin Accounts and Pledges. Individuals subject to Southwest's Blackout and Pre- Clearance Procedures are prohibited from holding Southwest securities in a margin account or pledging of Southwest securities as collateral for a loan. For others subject to this policy, such margin accounts and pledges are strongly discouraged. Permitted Transactions. Regardless of whether you are in possession of material nonpublic information, certain transactions are permitted: • Stock Options and Other Stock-Based Compensation. This policy does not restrict your exercise or settlement of a stock option or other stock-based compensation received under a Southwest plan or your exercise of a tax withholding right or net settlement pursuant to which Southwest withholds shares subject to an option or other security or shares that vest under a restricted stock grant or other award in order to satisfy tax withholding requirements or the exercise price. • Employee Stock Purchase Plan. This policy does not restrict your purchases of Southwest common stock through Southwest's Employee Stock Purchase Plan. • ProfitSharing Plan. This policy does not restrict Southwest's allocation of common stock to your account through Southwest's ProfitSharing Plan. • Automatic Reinvestment in Dividends. This policy does not restrict the automatic reinvestment of dividends paid on Southwest common stock. This policy does apply, however, to (i) your election to participate in automatic reinvestment of dividends and (ii) your election to increase or decrease your level of automatic reinvestment of dividends. • Mutual Funds. Transactions in diversified mutual funds that are invested in Southwest securities are not prohibited by this policy. • Rule 10b5-1 Plans. Transactions made pursuant to a Rule 10b5-1 Plan are permitted. You must obtain authorization from Southwest's Chief Legal Officer (or equivalent) before entering into, modifying, or terminating (other than by its normal terms) a Rule 10b5-1 Plan. • Other Transactions. Any transaction specifically approved in advance by Southwest's Chief Legal Officer (or equivalent) is permitted. Blackout and Pre-Clearance Procedures Under Southwest's Blackout and Pre-Clearance Procedures, Southwest may prohibit you from transacting in Southwest securities or the securities of other companies at any time. Southwest's Chief Legal Officer (or equivalent) will notify you in the event of such a prohibition.

![](exhibit191-insidertradin004.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;4 Definition of Material Nonpublic Information A determination as to whether information is "material" or "nonpublic" depends on all of the relevant facts and circumstances. The following is intended to serve as guidance in making such a determination. Material Information. Information is material if there is a substantial likelihood a reasonable investor would consider the information as significantly altering the total mix of information available. Thus, information may be material if it is likely that a reasonable investor would consider it important in deciding whether to buy, hold, or sell a security. Similarly, information may be material if you reasonably expect that it would affect the price of the security. Both positive and negative information can be material. Common examples of information that could be, but are not necessarily, material include: • Projections of future earnings or losses or other earnings guidance. • Earnings inconsistent with the consensus expectations of the investment community. • The current revenue environment, including advance bookings, yields, and load factors. • Expected capacity growth and new markets. • A pending or proposed merger, acquisition, or tender offer or an acquisition or disposition of significant assets. • A change in executive officers or certain members of the Board of Directors. • Major events related to Southwest securities, such as the declaration of a stock split, the announcement of a stock repurchase program, significant changes in the Southwest's dividend policy, or the offering of additional equity securities. • Significant changes in Southwest's or its subsidiaries' credit ratings. • Severe financial liquidity problems or bankruptcy. • Significant cybersecurity incidents. • Actual or threatened major litigation or the resolution of such litigation. • New major contracts, orders, suppliers, customers, or finance sources, or the loss thereof. Nonpublic Information. Nonpublic information is information not generally known or available to the public. Material information does not necessarily lose its "nonpublic" status as soon as a press release is issued disclosing the information. Therefore, to avoid uncertainty, information should be considered available to the public only when the information has been released broadly to the marketplace (such as by a press release or a filing with the Securities and Exchange Commission) and the investing public has had time to fully absorb the information. Generally, at least one full trading day should be allowed after the broad release of information before such information is deemed to be public. Depending on the particular circumstances, Southwest (through its Chief Legal Officer or equivalent) may determine that a longer or shorter period should apply to the release of specific, material information. Post-Termination Transactions This policy continues to apply even after your services for Southwest have terminated if you are aware of material nonpublic information at that time. If you are aware of material nonpublic

------

![](exhibit191-insidertradin005.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;5 information when your services for Southwest have terminated, you may not transact in Southwest securities until that information has become public or is no longer material. Questions Your compliance with this policy is important for you and for Southwest. If you have any questions about this policy, please contact Southwest's Chief Legal Officer (or equivalent). References in this policy to Southwest's Chief Legal Officer (or equivalent) mean Southwest's Chief Legal Officer (or equivalent) or the Chief Legal Officer's (or equivalent's) designee. This document states a policy of Southwest Airlines Co. and is not intended to be regarded as legal advice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;SOUTHWEST AIRLINES CO. Blackout and Pre-Clearance Procedures Applicable to Southwest's Board of Directors, Officers, and Certain Other Employees July 31, 2025 Southwest Airlines Co. has adopted these Blackout and Pre-Clearance Procedures to help prevent inadvertent violations of the federal securities laws and to help avoid the appearance of transacting in Southwest securities while in possession of material nonpublic information. These procedures supplement Southwest's Insider Trading Policy and apply to Southwest's Board of Directors, Officers, and certain other Employees as discussed below. Insiders should also adhere to the general prohibitions set forth in the Insider Trading Policy, whether or not Southwest has identified such insider as being in the "Blackout Group." Blackout Group All members of the Board of Directors, Officers, and other Employees who have been identified by Southwest's Chief Legal Officer (or equivalent) (generally, persons who routinely receive or have access to material nonpublic information about Southwest) (the "Blackout Group") are subject to the following blackout procedures. Blackout Procedures for Blackout Group Quarterly Blackout Periods. Members of the Blackout Group may not transact in Southwest securities during the quarterly period designated by Southwest's Chief Legal Officer (or equivalent) from time to time (the "Quarterly Blackout Period"). Transacting in Southwest securities outside of this period should not be considered a "safe harbor." Transactions discussed under "Permitted Transactions" in Southwest's Insider Trading Policy are not subject to the Quarterly Blackout Period. Event-Specific Blackouts. From time to time, Southwest (through its Chief Legal Officer or equivalent) may also subject certain members of the Blackout Group or other persons who are not members of the Blackout Group to an event-specific trading blackout (an "Event-Specific Blackout") because of the occurrence of an event that is material to Southwest or to another company. The event may be known by only a few members of the Blackout Group or other persons who are not members of the Blackout Group. So long as the event remains material and nonpublic, the Event-Specific Blackout will remain in place. The existence of the Event-Specific Blackout will usually be announced only to those who are aware of the event giving rise to the blackout. Any person made aware of the existence of an Event-Specific Blackout should not disclose the existence of the blackout to any other person (outside those subject to the Event-Specific Blackout) and may not transact in Southwest securities or, if applicable, securities of the other designated company, during the Event-Specific Blackout, except as discussed under "Permitted Transactions" in Southwest's Insider Trading Policy.

&nbsp;&nbsp;&nbsp;&nbsp;2 Mandatory Pre-Clearance Procedures for Blackout Group Regardless of whether a Quarterly Blackout Period or Event-Specific Blackout is in place, members of the Blackout Group are subject to the mandatory pre-clearance procedures discussed below. Such pre-clearance procedures do not apply to transactions conducted pursuant to Rule 10b5-1 Plans that Southwest's Chief Legal Officer (or equivalent) has already properly approved. Advance Notice of Transactions. Members of the Blackout Group may not engage in any transaction involving Southwest securities (including, without limitation, transactions such as option exercises, gifts, loans or pledges, contributions to trusts, or other transfers) unless and until pre-clearance has been obtained from Southwest's Chief Legal Officer (or equivalent) or such other person(s) as may be designated from time to time by Southwest. Transactions by (i) family members or anyone else who lives with a member of the Blackout Group, (ii) any family members who do not live with a member of the Blackout Group, but whose transactions in Southwest securities are directed by a member of the Blackout Group or are subject to such member's influence or control (such as parents or children who consult with you before they transact in Southwest securities), and (iii) partnerships, trusts, estates, and other entities that a member of the Blackout Group controls may be attributable to such member and must therefore also be pre- cleared. Once pre-clearance to engage in a transaction is obtained, a member of the Blackout Group must complete the transaction within the time period designated by Southwest's Chief Legal Officer (or equivalent) or such other person(s) as may be designated from time to time by Southwest. Please note that clearance of a proposed transaction does not constitute legal advice or otherwise acknowledge that a member of the Blackout Group does not possess material nonpublic information. Members of the Blackout Group must ultimately make their own judgments regarding, and are personally responsible for determining, whether they are in possession of material nonpublic information. Additional Prohibited Transactions for Blackout Group The following provisions apply from the date of these Blackout and Pre-Clearance Procedures forward unless an exception has been pre-approved in writing by the Chief Legal Officer (or equivalent) (which approval may be withheld in the Chief Legal Officer's (or equivalent's) sole discretion): Hedging Transactions. Hedging or monetization transactions involving Southwest securities are prohibited. Short Sales. Short sales involving Southwest securities are prohibited. Derivative Securities. Transactions in derivative securities involving Southwest securities are prohibited. This policy does not, however, restrict holding or exercising or settling options, restricted stock, restricted stock units, or other derivative securities granted under a Southwest equity compensation plan. Standing Orders. Members of the Blackout Group are prohibited from placing standing orders with respect to Southwest securities.

![](exhibit191-insidertradin008.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;3 Limit Orders. Members of the Blackout Group are prohibited from placing limit orders with respect to Southwest securities. Margin Accounts and Pledges. Members of the Blackout Group are prohibited from holding Southwest securities in a margin account or pledging Southwest securities as collateral for a loan. Company Assistance Your compliance with Southwest's Insider Trading Policy, including these Blackout and Pre-Clearance Procedures, is important both for you and for Southwest. If you have any questions about the Insider Trading Policy and these procedures, or their application to any proposed transaction, you may obtain additional guidance from Southwest's Chief Legal Officer (or equivalent). References in these procedures to Southwest's Chief Legal Officer (or equivalent) mean the Chief Legal Officer (or equivalent) or the Chief Legal Officer's (or equivalent's) designee.
