## A LETTER FROM OUR CEO TO OUR SHAREHOLDERS

## Dear Delta shareholder:

Delta Air Lines had a strong year on many fronts in 2017, delivering solid results for our employees, customers and owners, while also making significant investments in Delta’s future. We generated more than $5 billion in pre-tax income for the third consecutive year despite a number of challenges, including major weather events and a 12-hour power outage at our Atlanta hub. Through it all, Delta people provided our customers the very best service in the industry - showing that they are our greatest asset.

Our top financial priority in 2017 was to return the business to unit revenue growth. We took a number of actions to drive this result, including capping our capacity growth at 1% for the year. We also made investments in our product and people that are contributing to higher net promoter scores, demonstrating better customer satisfaction and a sustainable revenue premium. We enter 2018 with the best revenue momentum in years. Domestic demand and yields remain robust and global economies are rebounding, allowing us to resume growth in our international business.

Limiting our capacity growth helped produce revenue momentum, but it also created heightened pressure on our unit costs. Costs were further pressured by product investments, weather and accelerated depreciation on aircraft exiting our fleet. These impacts combined for unsustainable unit cost growth in 2017, and we are determined to change this trajectory in 2018. Our 2018 fleet additions are set to deliver some of the greatest efficiency gains in Delta’s history. In addition, we have started a company-wide project to drive productivity by better leveraging our scale and rethinking the way we do business.

In recent years, we have invested more than $2 billion in partnerships with some of the finest airlines in the world. These strong relationships allow us to offer more choices to our customers and expand globally in a more capital efficient way. In 2017 alone, we acquired a 10% stake in Air France-KLM, acquired a 49% stake in Grupo Aeroméxico and announced plans for joint ventures with Korean Air and WestJet. With these investments made, we have built the foundation to produce hundreds of millions of dollars in benefits in the coming years from serving some of the largest and fastest growing markets in the world.

As we look to 2018 and beyond, our focus is on delivering sustainable financial results by leveraging our five key competitive differentiators:

Our People and Culture - Our culture is the foundation of every decision we make at Delta and the key to every other competitive advantage that we have built. Ensuring that the incentives of our people are aligned with those of our customers and shareholders is vital to our success, which is why we are proud to offer our people one of the most generous profit-sharing programs of any company. Since we started our profit sharing program in 2007, it has paid out more than $6 billion, including at least $1 billion for each of the past four years. Our culture is also one of giving back to the communities we serve - in 2017 we contributed over $40 million as part of our annual commitment to give 1 percent of net income to key charitable organizations.

Our Industry-Leading Operational Reliability - We are constantly focused on ways to run a better, more reliable, customer-focused airline. We have made significant investments in our business and currently run the best operation in the global industry - in 2017 we ran 242 days without cancelling any mainline flights, including 90 days with no system cancellations on the entire Delta platform - a 10% increase from 2016. These results led to Delta’s recognition by FlightGlobal as the most on-time global airline - the first time a U.S. airline has earned this award.

Our Network - Our domestic network combines a focus on the most desirable markets with a balanced footprint between East and West coasts, and is optimally structured to capture premium revenue. Delta holds approximately 60% share in our four interior hubs (Atlanta, Minneapolis, Detroit and Salt Lake City), allowing us to take advantage of scale economies. We have also streamlined our international network with a focus on major and developing markets around the world through global partnerships. We are achieving many of the benefits of cross-border cooperation for our customers and our owners, with strong alliances in Europe, Latin America, Asia, Australia and Canada.



Our Customer Loyalty and Brand - During 2017, we achieved record customer satisfaction levels, with higher net promoter scores in every region and a 2-point improvement overall, including an all-time high in November 2017. We will continue to build on this success, with more than $12 billion of airport facility projects planned in the next decade. We are offering more customer choice through Branded Fares, including First Class upsell, Comfort+, Preferred Seats and Basic Economy, which combined generated nearly $2 billion of revenue in 2017. We are also growing our relationship with American Express - our co-brand partnership contributed $3 billion in 2017, which we expect to grow to $4 billion by 2021.

Our Investment Grade Balance Sheet - Since 2009, we have reduced the principal amount of our debt by more than $9 billion, which has lowered our annual interest expense by approximately $900 million and resulted in an investment grade credit rating from all three agencies. In addition, our pension funded status is at its highest level since the merger. Our long-term goal is to generate $8 - $9 billion in operating cash flow and $4 - $5 billion of free cash flow annually, which will be used to further pay down debt and continue to return cash to shareholders. In 2017, we returned $2.4 billion to shareholders through dividends and share repurchases and announced our fourth 50% dividend increase in as many years. Since 2013, we have returned nearly $10 billion to shareholders and have reduced our outstanding shares by 18%.

We are approaching the 10-year anniversary of the Delta-Northwest merger, and the transformation of our company and the airline industry over that decade has been unprecedented. We are financially stronger, consistently delivering and investing in a high-quality experience for our customers, and sharing our success with our people. We love our “Keep Climbing” tagline because it reminds us not only of the hard work it has taken to achieve our current success, but also that our greatest days are ahead of us.

## Part I

## ITEM 1. BUSINESS

## General

We provide scheduled air transportation for passengers and cargo throughout the United States ("U.S.") and around the world. Our global route network gives us a presence in every major domestic and international market. Our route network is centered around a system of hub, international gateway and key airports that we operate in Amsterdam, Atlanta, Boston, Detroit, London-Heathrow, Los Angeles, Minneapolis-St. Paul, New York-LaGuardia, New York-JFK, Paris-Charles de Gaulle, Salt Lake City, Seattle and Tokyo-Narita. Each of these operations includes flights that gather and distribute traffic from markets in the geographic region surrounding the hub or gateway to domestic and international cities and to other hubs or gateways. Our network is supported by a fleet of aircraft that is varied in size and capabilities, giving us flexibility to adjust aircraft to the network. Other important characteristics of our route network include our international joint ventures, our alliances with other foreign airlines, our membership in SkyTeam and agreements with multiple domestic regional carriers that operate as Delta Connection \( ^{®} \) .

We are incorporated under the laws of the State of Delaware. Our principal executive offices are located at Hartsfield-Jackson Atlanta International Airport in Atlanta, Georgia. Our telephone number is (404) 715-2600 and our Internet address is www.delta.com. Information contained on our website is not part of, and is not incorporated by reference in, this Form 10-K.

## International Alliances

Our international alliance relationships with foreign carriers are an important part of our business as they improve our access to international markets and enable us to market globally integrated air transportation services. The most significant of these arrangements are commercial joint ventures that include joint sales and marketing coordination, co-location of airport facilities and other commercial cooperation arrangements. Our alliance arrangements also include reciprocal codesharing and reciprocal frequent flyer program participation and airport lounge access arrangements. These alliance relationships also may present opportunities in other areas, such as airport ground handling arrangements, aircraft maintenance insourcing and joint procurement.

Joint Venture Agreements. We currently operate four joint ventures with foreign carriers and have entered into an agreement to form a fifth. These arrangements, for which we have received antitrust immunity from the U.S. Department of Transportation ("DOT"), provide for joint commercial cooperation with our partners within the geographic scope of those arrangements, including the sharing of revenues and/or profits and losses generated by the parties on the joint venture routes, as well as joint marketing and sales, coordinated pricing and revenue management, network planning and scheduling and other coordinated activities with respect to the parties' operations on joint venture routes. Our commercial joint ventures are:

• A transatlantic joint venture with Air France and KLM, both of which are subsidiaries of the same holding company, and Alitalia.

• A joint venture with Virgin Atlantic Airways with respect to operations on non-stop routes between the United Kingdom and North America. In addition to the joint venture, we own a non-controlling 49% equity stake in Virgin Atlantic Limited, the parent company of Virgin Atlantic Airways.

- A joint venture with Aeroméxico with respect to trans-border operations on flights between the U.S. and Mexico. In addition to the joint venture, we acquired a non-controlling 49% equity stake in Grupo Aeroméxico, S.A.B. de C.V., the parent company of Aeroméxico. In addition, we and Aeroméxico have established a joint venture relating to an airframe maintenance, repair and overhaul operation located in Queretaro, Mexico.

- A joint venture with Virgin Australia Airlines and its affiliated carriers with respect to operations on transpacific routes between North America and Australia/New Zealand.

- In 2017, we entered into a joint venture with Korean Air Lines with respect to operations on transpacific routes between the United States and certain countries in Asia. We have not yet implemented this joint venture as it remains subject to receipt of required regulatory approvals in Korea.



## Table of Contents

Enhanced Commercial Agreements with Foreign Carriers. We have a strategic equity investment in GOL Linhas Aéreas Inteligentes, S.A., the parent company of Gol Linhas Aéreas (a Brazilian air carrier), and an exclusive commercial cooperation relationship with GOL, which includes reciprocal codesharing and frequent flyer program participation, airport lounge access arrangements and joint sales cooperation.

We also own shares of China Eastern and entered into a joint marketing agreement with China Eastern in 2015 to expand our commercial cooperation and better connect the networks of the two airlines.

SkyTeam . In addition to our marketing alliance agreements with individual foreign airlines, we are a member of the SkyTeam global airline alliance. The other members of SkyTeam are Aeroflot, Aerolíneas Argentinas, Aeroméxico, Air Europa, Air France, Alitalia, China Airlines, China Eastern, China Southern, CSA Czech Airlines, Garuda Indonesia, Kenya Airways, KLM, Korean Air, Middle East Airlines, Saudi Arabian Airlines, Tarom, Vietnam Airlines and Xiamen Airlines. Through alliance arrangements with other SkyTeam carriers, Delta is able to link its network with the route networks of the other member airlines, providing opportunities for increased connecting traffic while offering enhanced customer service through reciprocal codesharing and frequent flyer arrangements, airport lounge access programs and coordinated cargo operations.

## Regional Carriers

We have air service agreements with domestic regional air carriers that feed traffic to our route system by serving passengers primarily in small and medium-sized cities. These arrangements enable us to better match capacity with demand in these markets. Approximately 16% of our passenger revenue in 2017 was related to flying by these regional air carriers.

Through our regional carrier program, Delta Connection, we have contractual arrangements with regional carriers to operate aircraft using our "DL" designator code. We have contractual arrangements with:

• ExpressJet Airlines, Inc. and SkyWest Airlines, Inc., both subsidiaries of SkyWest, Inc.;

• Republic Airline, Inc. ("Republic"), a subsidiary of Republic Airways Holdings, Inc.;

• Compass Airlines, LLC ("Compass") and GoJet Airlines, LLC, both subsidiaries of Trans States Holdings, Inc. ("Trans States"); and

• Endeavor Air, Inc., which is a wholly owned subsidiary of ours.

Our contractual agreements with regional carriers primarily are capacity purchase arrangements, under which we control the scheduling, pricing, reservations, ticketing and seat inventories for the regional carriers' flights operating under our "DL" designator code. We are entitled to all ticket, cargo, mail, in-flight and ancillary revenues associated with these flights. We pay those airlines an amount, as defined in the applicable agreement, which is based on a determination of their cost of operating those flights and other factors intended to approximate market rates for those services. These capacity purchase agreements are long-term agreements, usually with initial terms of at least 10 years, which grant us the option to extend the initial term. Certain of these agreements provide us the right to terminate the entire agreement, or in some cases remove some of the aircraft from the scope of the agreement, for convenience at certain future dates.

SkyWest Airlines operates some flights for us under a revenue proration agreement. This proration agreement establishes a fixed dollar or percentage division of revenues for tickets sold to passengers traveling on connecting flight itineraries.



## Frequent Flyer Program

Our SkyMiles \( ^{®} \)  frequent flyer program ("SkyMiles program") is designed to retain and increase traveler loyalty by offering incentives to customers to increase travel on Delta. The SkyMiles program allows program members to earn mileage credit for travel awards by flying on Delta, its regional carriers and other participating airlines. Mileage credit may also be earned by using certain services offered by program participants, such as credit card companies, hotels and car rental agencies. In addition, individuals may purchase mileage credits. Miles do not expire, but are subject to the program rules. We reserve the right to terminate the program with six months advance notice, and to change the program's terms and conditions at any time without notice.

SkyMiles program mileage credits can be redeemed for air travel on Delta and participating airlines, for membership in our Delta Sky Clubs \( ^{®} \)  and for other program participant awards. Mileage credits are subject to certain transfer restrictions and travel awards on partner airlines are subject to capacity-controlled seating. We offer last-seat availability for travel awards on our own flights (including most Delta Connection flights). In 2017, program members redeemed more than 345 billion miles in the SkyMiles program for 14.9 million award redemptions. During this period, 7.9% of revenue miles flown on Delta were from award travel.

## Fuel

Our results of operations are significantly impacted by changes in the price and availability of aircraft fuel. The following table shows our aircraft fuel consumption and costs.

<table><tr><td>Year</td><td>Gallons Consumed (1) (in millions)</td><td>Cost (1)(2) (in millions)</td><td>Average Price Per Gallon (1)(2)</td><td>Percentage of Total Operating Expense (1)(2)</td></tr><tr><td>2017</td><td>4,032</td><td>$ 6,756</td><td>$ 1.68</td><td>19.2%</td></tr><tr><td>2016</td><td>4,016</td><td>$ 5,985</td><td>$ 1.49</td><td>18.3%</td></tr><tr><td>2015</td><td>3,988</td><td>$ 7,579</td><td>$ 1.90</td><td>23.0%</td></tr></table>

(1) Includes the operations of our regional carriers operating under capacity purchase agreements.

(2) Includes the impact of fuel hedge activity and refinery segment results.

## General

We purchase most of our aircraft fuel under contracts that establish the price based on various market indices and therefore do not provide material protection against price increases or assure the availability of our fuel supplies. We also purchase aircraft fuel on the spot market, from off-shore sources and under contracts that permit the refiners to set the price.

## Monroe Energy

Our wholly owned subsidiaries, Monroe Energy, LLC and MIPC, LLC (collectively, "Monroe") operate the Trainer refinery and related assets located near Philadelphia, Pennsylvania. The facilities include pipelines and terminal assets that allow the refinery to supply jet fuel to our airline operations throughout the Northeastern U.S., including our New York hubs at LaGuardia and JFK. These companies are distinct from us, operating under their own management teams and with their own boards of managers. We own Monroe as part of our strategy to mitigate the cost of the refining margin reflected in the price of jet fuel, as well as to maintain sufficiency of supply to our New York operations.

Refinery Operations. The facility is capable of refining approximately 200,000 barrels of crude oil per day. In addition to jet fuel, the refinery's production consists of gasoline, diesel and other refined products ("non-jet fuel products"). Monroe sources domestic and foreign crude oil supply from a variety of providers.

Strategic Agreements. Monroe exchanges the non-jet fuel products the refinery produces with third parties for jet fuel consumed in our airline operations.

Segments. Because the products and services of Monroe's refinery operations are discrete from our airline services, segment results are prepared for our airline segment and our refinery segment. Financial information on our segment reporting can be found in Note 14 of the Notes to the Consolidated Financial Statements.



## Table of Contents

## Fuel Hedging Program

We have recently managed our fuel price risk through a hedging program intended to reduce the financial impact from changes in the price of fuel as fuel prices are subject to potential volatility. We may utilize different contract and commodity types in this program and frequently test their economic effectiveness against our financial targets. We closely monitor the hedge portfolio and rebalance the portfolio based on market conditions, which may result in locking in gains or losses on hedge contracts prior to their settlement dates. In addition, we enter into derivatives with third parties to hedge financial risk related to Monroe’s refining margins.

## Fuel Supply Availability

We are currently able to obtain adequate supplies of aircraft fuel, including fuel produced by Monroe or procured through the exchange of non-jet fuel products the refinery produces, and crude oil for Monroe's operations. However, it is impossible to predict the future availability or price of aircraft fuel and crude oil. Weather-related events, natural disasters, political disruptions or wars involving oil-producing countries, changes in government policy concerning aircraft fuel production, transportation, taxes or marketing, changes in refining capacity, environmental concerns and other unpredictable events may result in future fuel supply shortages and fuel price increases.

## Other Businesses

## Cargo

Through our global network, our cargo operations are able to connect the world's major freight gateways. We generate cargo revenues in domestic and international markets through the use of cargo space on regularly scheduled passenger aircraft. We are a member of SkyTeam Cargo, a global airline cargo alliance, whose other members are Aeroflot, Aerolíneas Argentinas, Aeroméxico Cargo, Air France-KLM Cargo, Alitalia Cargo, China Airlines Cargo, China Cargo Airlines, China Southern Cargo, Czech Airlines Cargo and Korean Air Cargo. SkyTeam Cargo offers a global network spanning six continents.

## Ancillary Businesses

We have several other businesses arising from our airline operations, including aircraft maintenance, repair and overhaul ("MRO"), staffing and other services, vacation wholesale operations and our private jet operations. In 2017, the total revenue from these businesses was approximately $1 billion.

- In addition to providing maintenance and engineering support for our fleet of over 900 aircraft, our MRO operation, known as Delta TechOps, serves aviation and airline customers from around the world.

- Delta Global Services provides services to us and to third parties, including staffing services, aviation solutions, professional security and training services.

• Our vacation wholesale business, Delta Vacations, provides vacation packages to third-party consumers.

- Our private jet operations, Delta Private Jets, provides aircraft charters, aircraft management and programs allowing members to purchase flight time by the hour.

## Distribution and Expanded Product Offerings

Our tickets are sold through various distribution channels, including: (1) digital channels, such as delta.com and mobile applications/web, (2) telephone reservations, (3) online travel agencies and (4) traditional "brick and mortar" and other agencies. We make fare and product information widely available across those channels, ensuring customers always receive the best information and service options. An increasing number of our tickets are sold through Delta digital direct channels, driving more direct, personalized interactions with our customers and reducing distribution costs.



## Table of Contents

We have transformed distribution to a more retail oriented, merchandised approach by introducing well-defined and differentiated products for our customers. We offer distinct travel experiences with clear value propositions that enable customer choice. Delta One \( ^{TM} \) , Delta Premium Select, First Class and Delta Comfort+ \( ^{TM} \)  include varying premium amenities and services while Main Cabin and Basic Economy allow varying levels of pre-travel flexibility as well as exceptional service once onboard the aircraft. We expect that these merchandising initiatives as implemented across all of Delta's distribution channels will allow customers to better understand our product offerings, make it easier to buy the products they desire and increase customer satisfaction. This merchandising effort is most effective in Delta's digital channels where customers can compare all product options in a single, easy to understand display.

## Technology Transformation

Significant progress was made in 2017 in the transformation of our information technology function to improve operational reliability and enhance disaster recovery capabilities. Most significantly, we opened a new data center to provide redundancy for our key systems and continue the enhancement of that facility. We also reduced the risk of technology system failures to our operations through additional disaster recovery processes and heightened emphasis on our information security program including through the hiring of an experienced information security professional as our Chief Information Security Officer.

We are engaged in a digital transformation by continuing to invest in technology that supports our operations and provides tools for our employees, with our long term goal to convert our technology into a competitive advantage. These investments include improvements to infrastructure and technology architecture to unify and improve access to data sources and continue innovations in customer facing applications. This digital transformation will enhance interactions with our customers and allow us to deliver more personalized service, further enhancing the customer experience and strengthening our brand and competitive position.

## Competition

The airline industry is highly competitive, marked by significant competition with respect to routes, fares, schedules (both timing and frequency), services, products, customer service and frequent flyer programs. The industry has evolved through mergers and new entry, both domestically and internationally, and changes in international alliances. Consolidation in the airline industry, the rise of well-funded government sponsored international carriers, changes in international alliances and the creation of immunized joint ventures have altered, and will continue to alter, the competitive landscape in the industry, resulting in the formation of airlines and alliances with increased financial resources, more extensive global networks and more competitive cost structures.

## Domestic

Our domestic operations are subject to competition from traditional network carriers, including American Airlines and United Airlines, national point-to-point carriers, including Alaska Airlines, JetBlue Airways and Southwest Airlines, and discount carriers, some of which may have lower costs than we do and provide service at low fares to destinations served by us. Point-to-point, discount and ultra low-cost carriers, including Spirit Airlines and Allegiant Air, place significant competitive pressure on network carriers in the domestic market. In particular, we face significant competition at our domestic hub and gateway airports either directly at those airports or at the hubs of other airlines that are located in close proximity to our hubs and gateways. We also face competition in smaller to medium-sized markets from regional jet operations of other carriers.

## International

Our international operations are subject to competition from both foreign and domestic carriers. Competition is increasing from government-owned and -funded carriers in the Gulf region, including Emirates, Etihad Airways and Qatar Airways. These carriers have large numbers of international widebody aircraft on order and are increasing service to the U.S. These carriers are government-subsidized, which has allowed them to grow quickly, reinvest in their product and expand their global presence at the expense of U.S. airlines.

Through alliance and other marketing and codesharing agreements with foreign carriers, U.S. carriers have increased their ability to sell international transportation, such as services to and beyond traditional European and Asian gateway cities. Similarly, foreign carriers have obtained increased access to interior U.S. passenger traffic beyond traditional U.S. gateway cities through these relationships. In particular, alliances formed by domestic and foreign carriers, including SkyTeam, the Star Alliance (among United Airlines, Lufthansa German Airlines, Air Canada and others) and the onward alliance (among American Airlines, British Airways, Qantas and others) have enhanced competition in international markets.



## Table of Contents

In addition, several joint ventures among U.S. and foreign carriers, including our transatlantic and transpacific joint ventures, have received grants of antitrust immunity allowing the participating carriers to coordinate schedules, pricing, sales and inventory. Other joint ventures that have received antitrust immunity include a transatlantic alliance among United Airlines, Air Canada and Lufthansa German Airlines, a transpacific joint venture between United Airlines and All Nippon Airways, a transatlantic joint venture among American Airlines, British Airways and Iberia and a transpacific joint venture between American Airlines and Japan Air Lines.

## Regulatory Matters

The DOT and the Federal Aviation Administration (the "FAA") exercise regulatory authority over air transportation in the U.S. The DOT has authority to issue certificates of public convenience and necessity required for airlines to provide domestic air transportation. An air carrier that the DOT finds fit to operate is given authority to operate domestic and international air transportation (including the carriage of passengers and cargo). Except for constraints imposed by regulations regarding "Essential Air Services," which are applicable to certain small communities, airlines may terminate service to a city without restriction.

The DOT has jurisdiction over certain economic and consumer protection matters, such as unfair or deceptive practices and methods of competition, advertising, denied boarding compensation, baggage liability and disabled passenger transportation. The DOT also has authority to review certain joint venture agreements between domestic and international carriers and engages in regulation of economic matters such as slot transactions. The FAA has primary responsibility for matters relating to the safety of air carrier flight operations, including airline operating certificates, control of navigable air space, flight personnel, aircraft certification and maintenance and other matters affecting air safety.

Authority to operate international routes and international codesharing arrangements is regulated by the DOT and by the governments of the foreign countries involved. International certificate authorities are also subject to the approval of the U.S. President for conformance with national defense and foreign policy objectives.

The Transportation Security Administration and the U.S. Customs and Border Protection, each a division of the Department of Homeland Security, are responsible for certain civil aviation security matters, including passenger and baggage screening at U.S. airports and international passenger prescreening prior to entry into or departure from the U.S.

Airlines are also subject to various other federal, state, local and foreign laws and regulations. For example, the U.S. Department of Justice has jurisdiction over airline competition matters. The U.S. Postal Service has authority over certain aspects of the transportation of mail. Labor relations in the airline industry, as discussed below, are generally governed by the Railway Labor Act. Environmental matters are regulated by various federal, state, local and foreign governmental entities. Privacy of passenger and employee data is regulated by domestic and foreign laws and regulations.

## Fares and Rates

Airlines set ticket prices in all domestic and most international city pairs with minimal governmental regulation, and the industry is characterized by significant price competition. Certain international fares and rates are subject to the jurisdiction of the DOT and the governments of the foreign countries involved. Many of our tickets are sold by travel agents, and fares are subject to commissions, overrides and discounts paid to travel agents, brokers and wholesalers.



## Route Authority

Our flight operations are authorized by certificates of public convenience and necessity and also by exemptions and limited-entry frequency awards issued by the DOT. The requisite approvals of other governments for international operations are controlled by bilateral agreements (and a multilateral agreement in the case of the U.S. and the European Union) with, or permits or approvals issued by, foreign countries. Because international air transportation is governed by bilateral or other agreements between the U.S. and the foreign country or countries involved, changes in U.S. or foreign government aviation policies could result in the alteration or termination of such agreements, diminish the value of our international route authorities or otherwise affect our international operations. Bilateral agreements between the U.S. and various foreign countries served by us are subject to renegotiation from time to time. The U.S. government has negotiated "Open Skies" agreements with many countries, which allow unrestricted access between the U.S. and the foreign markets. These agreements include separate agreements with the European Union and Japan.

Certain of our international route authorities are subject to periodic renewal requirements. We request extension of these authorities when and as appropriate. While the DOT usually renews temporary authorities on routes where the authorized carrier is providing a reasonable level of service, there is no assurance this practice will continue in general or with respect to a specific renewal. Dormant route authorities may not be renewed in some cases, especially where another U.S. carrier indicates a willingness to provide service.

## Airport Access

Operations at three major domestic airports and certain foreign airports served by us are regulated by governmental entities through allocations of "slots" or similar regulatory mechanisms which limit the rights of carriers to conduct operations at those airports. Each slot represents the authorization to land at or take off from the particular airport during a specified time period.

In the U.S., the FAA currently regulates the allocation of slots, slot exemptions, operating authorizations, or similar capacity allocation mechanisms at Reagan National in Washington, D.C. and LaGuardia and JFK in the New York City area. Our operations at these airports generally require the allocation of slots or analogous regulatory authorizations. Similarly, our operations at Tokyo's Narita and Haneda airports, London's Heathrow airport and other international airports are regulated by local slot coordinators pursuant to the International Air Transport Association's Worldwide Scheduling Guidelines and applicable local law. We currently have sufficient slots or analogous authorizations to operate our existing flights, and we have generally been able to obtain the rights to expand our operations and to change our schedules. There is no assurance, however, that we will be able to do so in the future because, among other reasons, such allocations are subject to changes in governmental policies.

## Environmental Matters

Our operations are subject to a number of international, federal, state and local laws and regulations governing protection of the environment, including regulation of greenhouse gases and other air emissions, noise reduction, water discharges, aircraft drinking water, storage and use of petroleum and other regulated substances, and the management and disposal of hazardous waste, substances and materials.

Emissions. Greenhouse gas emissions by the aviation industry and their impact on climate change have become a particular focus in the international community and within the U.S. For several years, the European Union has required its member states to implement regulations to include aviation in its Emissions Trading Scheme ("ETS"). Under these regulations, any airline with flights originating or landing in the European Union is subject to the ETS and, beginning in 2012, was required to purchase emissions allowances if the airline exceeds the number of free allowances allocated to it under the ETS. The ETS was amended to apply only to flights within the European Economic Area from 2013 through 2016. In 2017, the EU extended the exemption for foreign flights through 2023 given the International Civil Aviation Organization's ("ICAO") adoption of a global market-based program.



## Table of Contents

In October 2016, ICAO formally adopted a global, market-based emissions offset program known as the Carbon Offsetting and Reduction Scheme for International Aviation. This program is designed to achieve a medium-term goal for the aviation industry of achieving carbon-neutral growth in international aviation beginning in 2020. A pilot phase of the offset program will begin in 2021, followed by a first phase of the program beginning in 2024 and a second phase beginning in 2027. Countries can voluntarily participate in the pilot and first phase, but participation in the second phase is mandatory. In 2016, ICAO also adopted new aircraft certification standards to reduce carbon dioxide  \( \left(\mathrm{CO}_{2}\right) \)  emissions from aircraft. The new aircraft certification standards will apply to new aircraft types in 2020 and to new in-production aircraft starting in 2023 but no later than 2028. It is important to note that the standards will not apply to existing in-service aircraft. However, exemption from the certification requirement would provide no protection from taxation schemes based on  \( CO_{2} \)  emissions.

In July 2016, the U.S. Environmental Protection Agency ("EPA") issued a final finding under the Clean Air Act that greenhouse gases threaten the public health and welfare, and further determined that aircraft cause or contribute to greenhouse gases. The endangerment finding does not establish standards, but triggers an obligation for the EPA to regulate greenhouse gas emissions from aircraft. The EPA has historically implemented air emissions control standards adopted by ICAO; therefore, the ICAO aircraft engine certification standards are expected to influence the development of any EPA greenhouse gas emission standards for aircraft.

We may face additional regulation of aircraft emissions in the U.S. and abroad and become subject to further taxes, charges or additional requirements to obtain permits or purchase allowances or emission credits for greenhouse gas emissions in various jurisdictions. Additional regulation could result in taxation or permitting requirements from multiple jurisdictions for the same operations and significant costs for us and the airline industry. In addition to direct costs, such regulation could result in increased fuel costs passed through from fuel suppliers affected by any such regulations. We are monitoring and evaluating the potential impact of such legislative and regulatory developments.

We seek to minimize the impact of greenhouse gas emissions from our operations through reductions in our fuel consumption and other efforts, and have realized reductions in our greenhouse gas emission levels since 2005. We have reduced the fuel needs of our aircraft fleet through the retirement of older, less fuel efficient aircraft and replacement with newer, more fuel efficient aircraft. In addition, we have implemented fuel saving procedures in our flight and ground support operations that further reduce carbon emissions. We are also supporting efforts to develop alternative fuels and efforts to modernize the air traffic control system in the U.S. as part of our efforts to reduce our emissions and minimize our impact on the environment.

Noise . The Airport Noise and Capacity Act of 1990 recognizes the rights of operators of airports with noise problems to implement local noise abatement programs so long as such programs do not interfere unreasonably with interstate or foreign commerce or the national air transportation system. This statute generally provides that local noise restrictions on Stage 3 aircraft first effective after October 1, 1990, require FAA approval. While we have had sufficient scheduling flexibility to accommodate local noise restrictions in the past, our operations could be adversely impacted if locally-imposed regulations become more restrictive or widespread. In addition, foreign governments may allow airports to enact similar restrictions, which could adversely impact our international operations or require significant expenditure in order for our aircraft to comply with the restrictions.

Refinery Matters . Monroe's operation of the Trainer refinery is subject to numerous environmental laws and extensive regulations, including those relating to the discharge of materials into the environment, waste management, pollution prevention measures and greenhouse gas emissions.

Under the Energy Independence and Security Act of 2007, the EPA has adopted Renewable Fuel Standards ("RFS") that mandate the blending of renewable fuels into gasoline and on-road diesel ("Transportation Fuels"). Renewable Identification Numbers ("RINs") are assigned to renewable fuels produced or imported into the U.S. that are blended into Transportation Fuels to demonstrate compliance with this obligation. A refinery may meet its obligation under RFS by blending the necessary volumes of renewable fuels with Transportation Fuels or by purchasing RINs in the open market or through a combination of blending and purchasing RINs. Because the refinery operated by Monroe does not blend renewable fuels, it must purchase its RINs requirement in the secondary market or obtain a waiver from the EPA.

Other Environmental Matters . We are subject to certain environmental laws and contractual obligations governing the management and release of regulated substances, which may require the investigation and remediation of affected sites. Soil and/or ground water impacts have been identified at certain of our current or former leaseholds at several domestic airports. To address these impacts, we have a program in place to investigate and, if appropriate, remediate these sites. Although the ultimate outcome of these matters cannot be predicted with certainty, we believe that the resolution of these matters will not have a material adverse effect on our Consolidated Financial Statements.

## Civil Reserve Air Fleet Program

We participate in the Civil Reserve Air Fleet program (the "CRAF Program"), which permits the U.S. military to use the aircraft and crew resources of participating U.S. airlines during airlift emergencies, national emergencies or times of war. We have agreed to make available under the CRAF Program a portion of our international aircraft during the contract period ending September 30, 2018. The CRAF Program has only been activated twice since it was created in 1951.

## Employee Matters

## Railway Labor Act

Our relations with labor unions representing our airline employees in the U.S. are governed by the Railway Labor Act. Under the Railway Labor Act, a labor union seeking to represent an unrepresented craft or class of employees is required to file with the National Mediation Board (the "NMB") an application alleging a representation dispute, along with authorization cards signed by at least 50% of the employees in that craft or class. The NMB then investigates the dispute and, if it finds the labor union has obtained a sufficient number of authorization cards, conducts an election to determine whether to certify the labor union as the collective bargaining representative of that craft or class. A labor union will be certified as the representative of the employees in a craft or class if more than 50% of votes cast are for that union. A certified labor union would commence negotiations toward a collective bargaining agreement with the employer.

Under the Railway Labor Act, a collective bargaining agreement between an airline and a labor union does not expire, but instead becomes amendable as of a stated date. Either party may request that the NMB appoint a federal mediator to participate in the negotiations for a new or amended agreement. If no agreement is reached in mediation, the NMB may determine, at any time, that an impasse exists and offer binding arbitration. 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 the U.S. President appoints a Presidential Emergency Board ("PEB") to investigate and report on the dispute. The appointment of a PEB maintains the "status quo" for an additional 60 days. 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 imposition of proposed changes to the collective bargaining agreement by the airline. Congress and the President have the authority to prevent self help by enacting legislation that, among other things, imposes a settlement on the parties.

## Collective Bargaining

As of December 31, 2017, we had approximately 87,000 full-time equivalent employees, approximately 19% of whom were represented by unions. The following table shows our domestic airline employee groups that are represented by unions.

<table><tr><td>Employee Group</td><td>Approximate Number of Active Employees Represented</td><td>Union</td><td>Date on which Collective Bargaining Agreement Becomes Amendable</td></tr><tr><td>Delta Pilots</td><td>13,234</td><td>ALPA</td><td>December 31, 2019</td></tr><tr><td>Delta Flight Superintendents (Dispatchers)</td><td>420</td><td>PAFCA</td><td>March 31, 2018</td></tr><tr><td>Endeavor Air Pilots</td><td>1,805</td><td>ALPA</td><td>January 1, 2024</td></tr><tr><td>Endeavor Air Flight Attendants</td><td>1,160</td><td>AFA</td><td>December 31, 2018</td></tr><tr><td>Endeavor Air Dispatchers</td><td>55</td><td>PAFCA</td><td>December 31, 2018</td></tr></table>

In addition, 192 refinery employees of Monroe are represented by the United Steel Workers under an agreement that expires on February 28, 2019. This agreement is governed by the National Labor Relations Act ("NLRA"), which generally allows either party to engage in self help upon the expiration of the agreement.

Labor unions periodically engage in organizing efforts to represent various groups of our employees, including at our operating subsidiaries, that are not represented for collective bargaining purposes.

## ITEM 1A. RISK FACTORS

## Risk Factors Relating to Delta

Our business and results of operations are dependent on the price of aircraft fuel. High fuel costs or cost increases, including in the cost of crude oil, could have a material adverse effect on our operating results.

Our operating results are significantly impacted by changes in the price of aircraft fuel. Over the last decade, fuel prices have increased substantially at times and have been highly volatile during the last several years. In 2017, our average fuel price per gallon, including the impact of fuel hedges, was $1.68, a 12.8% increase from our average fuel price in 2016. In 2016, our average fuel price per gallon was $1.49, a 21.6% decrease from our average fuel price in 2015. In 2015, our average fuel price per gallon was $1.90, a 45.2% decrease from our average fuel price in 2014. Fuel costs represented 19.2%, 18.3% and 23.0% of our operating expense in 2017, 2016 and 2015, respectively.

Our ability to pass along rapidly increasing fuel costs to our customers may be affected by the competitive nature of the airline industry. Because passengers often purchase tickets well in advance of their travel, a significant rapid increase in fuel price may result in the fare charged not covering that increase. At times in the past, we often were not able to increase our fares to offset fully the effect of increases in fuel costs, and we may not be able to do so in the future.

We acquire a significant amount of jet fuel from our wholly owned subsidiary, Monroe, and through strategic agreements that Monroe has with third parties. The cost of the fuel we purchase under these arrangements remains subject to volatility in the cost of crude oil and jet fuel. In addition, we continue to purchase a significant amount of aircraft fuel in addition to what we obtain from Monroe. Our aircraft fuel purchase contracts alone do not provide material protection against price increases as these contracts typically establish the price based on industry standard market price indices.

Fuel hedging activities are intended to manage the financial impact of the volatility in the price of jet fuel. The effects of rebalancing our hedge portfolio and mark-to-market adjustments may have a negative effect on our financial results.

We have recently managed our fuel price risk through a hedging program intended to reduce the financial impact from changes in the price of fuel as fuel prices are subject to potential volatility. We may utilize different contract and commodity types in this program and test their economic effectiveness against our financial targets. We closely monitor the hedge portfolio and rebalance the portfolio based on market conditions, which may result in locking in gains or losses on hedge contracts prior to their settlement dates. Our hedging program may not be successful in providing price protection due to market conditions and the choice of hedging instruments. In addition, we record mark-to-market adjustments ("MTM adjustments") on our fuel hedges. MTM adjustments are based on market prices at the end of the reporting period for contracts settling in future periods. Losses from rebalancing or MTM adjustments (or both) may have a negative impact on our financial results.

Our fuel hedge contracts may contain margin funding requirements, which require us to post margin to counterparties or cause counterparties to post margin to us as market prices in the underlying hedged items change. If fuel prices decrease significantly from the levels existing at the time we enter into fuel hedge contracts, we may be required to post a significant amount of margin, which could have a material impact on the level of our unrestricted cash and cash equivalents and short-term investments.

Significant extended disruptions in the supply of aircraft fuel, including from Monroe, could have a material adverse effect on our operations and operating results.

Weather-related events, natural disasters, political disruptions or wars involving oil-producing countries, changes in governmental policy concerning aircraft fuel production, transportation, taxes or marketing, changes in refining capacity, environmental concerns and other unpredictable events may impact crude oil and fuel supply and could result in shortages in the future. Shortages in fuel supplies could have negative effects on our results of operations and financial condition.



Because we acquire a large amount of our jet fuel from Monroe, the disruption or interruption of production at the refinery could have an impact on our ability to acquire jet fuel needed for our operations. Disruptions or interruptions of production at the refinery could result from various sources including a major accident or mechanical failure, interruption of supply or delivery of crude oil, work stoppages relating to organized labor issues, or damage from severe weather or other natural or man-made disasters, including acts of terrorism. If the refinery were to experience an interruption in operations, disruptions in fuel supplies could have negative effects on our results of operations and financial condition. In addition, the financial benefits from the operation of the refinery could be materially adversely affected (to the extent not recoverable through insurance) because of lost production and repair costs.

If Monroe's cost of producing non-jet fuel products exceeds the value it receives for those products, the financial benefits we expect to achieve through the ownership of the refinery and our consolidated results of operations could be materially adversely affected.

Our significant investments in airlines in other parts of the world and the commercial relationships that we have with those carriers may not produce the returns or results we expect.

An important part of our strategy to expand our global network has been to make significant investments in airlines in other parts of the world and expand our commercial relationships with these carriers. We expect to continue exploring ways to expand our relationships with other carriers as part of our global business strategy. These investments and relationships involve significant challenges and risks, including that we may not realize a satisfactory return on our investment, that they may distract management from our operations or that they may not generate the expected revenue synergies. These events could have a material adverse effect on our operating results or financial condition.

In addition, we are dependent on these other carriers for significant aspects of our network in the regions in which they operate. While we work closely with these carriers, we do 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 of time or their actions subject us to the consequences of failure to comply with laws and regulations, our results of operations may be adversely affected. We also may be subject to consequences from any improper behavior of joint venture partners, including for failure to comply with anti-corruption laws such as the United States Foreign Corrupt Practices Act.

We are at risk of losses and adverse publicity stemming from a serious accident involving our aircraft or aircraft of our airline partners.

An aircraft crash or other serious accident could expose us to significant liability. Although we believe that our insurance coverage is appropriate, we may be forced to bear substantial losses from an accident in the event that the coverage was not sufficient.

In addition, any accident involving an aircraft that we operate or an aircraft that is operated by an airline that is one of our regional carriers or codeshare, alliance or joint venture partners could create a negative public perception about safety, which could harm our reputation, resulting in air travelers being reluctant to fly on our aircraft and therefore harm our business.

Breaches or lapses in the security of our technology systems and the data we store could compromise passenger or employee information and expose us to liability, possibly having a material adverse effect on our business.

As a regular part of our ordinary business operations, we collect and store sensitive data, including personal information of our passengers and employees and information of our business partners. The secure operation of the networks and systems on which this type of information is stored, processed and maintained is critical to our business operations and strategy.



Our information systems are subject to an increasing threat of continually evolving cybersecurity risks. Unauthorized parties may attempt to gain access to our systems or information, including through fraud or other means of deception. Hardware or software we develop or acquire may contain defects that could unexpectedly compromise information security. The methods used to obtain unauthorized access, disable or degrade service or sabotage systems are constantly evolving and may be difficult to anticipate or to detect for long periods of time. As a result of these types of risks and regular attacks, we regularly review and update procedures and processes to prevent and protect against unauthorized access to our systems and information and inadvertent misuse of data. However, the constantly changing nature of the threats means that we may not be able to prevent all data security breaches or misuse of data. The compromise of our technology systems resulting in the loss, disclosure, misappropriation of, or access to, customers', employees' or business partners' information or failure to comply with regulatory or contractual obligations with respect to such information could result in legal claims or proceedings, liability or regulatory penalties under laws protecting the privacy of personal information, disruption to our operations and damage to our reputation, any or all of which could adversely affect our business.

## Disruptions of our information technology infrastructure could interfere with our operations, possibly having a material adverse effect on our business.

Disruptions in our information technology network could result from a technology error or failure impacting our internal systems, whether hosted internally at our data centers or externally at third-party locations, or large scale external interruption in technology infrastructure support on which we depend, such as power, telecommunications or the internet. The operation of our technology systems and the use of related data may also be vulnerable to a variety of other sources of interruption, including natural disasters, terrorist attacks, computer viruses, hackers and other security issues. A significant individual, sustained or repeated failure of our network, including third-party networks we utilize and on which we depend, could impact our customer service and result in increased costs. While we have in place initiatives to prevent disruptions and disaster recovery plans and continue to invest in improvements to these initiatives and plans, these measures may not be adequate to prevent a business disruption and its adverse financial and reputational consequences to our business.

## Failure of our technology to perform effectively could have an adverse effect on our business.

We are dependent on technology initiatives to provide customer service and operational effectiveness in order to compete in the current business environment. For example, we have made and continue to make significant investments in customer facing technology such as delta.com, mobile device applications, check-in kiosks, customer service applications, airport information displays and related initiatives, including security for these initiatives. We are also investing in significant upgrades to technology infrastructure and other supporting systems. The performance, reliability and security of the technology are critical to our ability to serve customers. If our technology does not perform effectively, our business and operations would be negatively affected, which could be material.

Agreements governing our debt, including credit agreements, include financial and other covenants. Failure to comply with these covenants could result in events of default.

Our credit facilities have various financial and other covenants that require us to maintain, depending on the particular agreement, minimum fixed charge coverage ratios, minimum liquidity and/or minimum collateral coverage ratios. The value of the collateral that has been pledged in each facility may change over time due to appraisals of collateral required by our credit agreements and indentures. These changes could result from factors that are not under our control. A decline in the value of collateral could result in a situation where it may be difficult to maintain the collateral coverage ratio. In addition, the credit facilities contain other negative covenants customary for such financings. These covenants are subject to important exceptions and qualifications. If we fail to comply with these covenants and are unable to remedy or obtain a waiver or amendment, an event of default would result.

The credit facilities also contain other events of default customary for such financings. If an event of default were to occur, the lenders could, among other things, declare outstanding amounts due and payable. In addition, an event of default or declaration of acceleration under any of the credit facilities could also result in an event of default under other of our financing agreements. The acceleration of significant amounts of debt could require us to renegotiate, repay or refinance the obligations under the credit facilities or other financing arrangements.



## Table of Contents

Employee strikes and other labor-related disruptions may adversely affect our operations.

Our business is labor intensive, utilizing large numbers of pilots, flight attendants, aircraft maintenance technicians, ground support personnel and other personnel. As of December 31, 2017, approximately 19% of our workforce, primarily pilots, was unionized. Relations between air carriers and labor unions in the United States are governed by the Railway Labor Act, which provides that a collective bargaining agreement between an airline and a labor union does not expire, but instead becomes amendable as of a stated date. The Railway Labor Act generally prohibits strikes or other types of self-help actions both before and after a collective bargaining agreement becomes amendable, unless and until the collective bargaining processes required by the Railway Labor Act have been exhausted. Monroe's relations with unions representing its employees are governed by the NLRA, which generally allows self help after a collective bargaining agreement expires.

If we or our subsidiaries are unable to reach agreement with any of our unionized work groups on future negotiations regarding the terms of their collective bargaining agreements or if additional segments of our workforce become unionized, we may be subject to work interruptions or stoppages, subject to the requirements of the Railway Labor Act or the NLRA, as the case may be. Strikes or labor disputes with our unionized employees may adversely affect our ability to conduct business. Likewise, if third-party regional carriers with whom we have contract carrier agreements are unable to reach agreement with their unionized work groups in current or future negotiations regarding the terms of their collective bargaining agreements, those carriers may be subject to work interruptions or stoppages, subject to the requirements of the Railway Labor Act, which could have a negative impact on our operations.

## Our results can fluctuate due to the effects of weather, natural disasters and seasonality.

Our results of operations are impacted by severe weather, natural disasters and seasonality. Severe weather conditions and natural disasters (or other environmental events) can significantly disrupt service and create air traffic control problems. These events decrease revenue and can also increase costs. In addition, increases in the frequency, severity or duration of thunderstorms, hurricanes, typhoons or other severe weather events, including from changes in the global climate, could result in increases in delays and cancellations, turbulence-related injuries and fuel consumption to avoid such weather, any of which could result in loss of revenue and higher costs. In addition, demand for air travel is typically higher in the June and September quarters, particularly in international markets, because there is more vacation travel during these periods than during the remainder of the year. The seasonal shifting of demand causes our financial results to vary on a seasonal basis. Because of fluctuations in our results from weather, natural disasters and seasonality, operating results for a historical period are not necessarily indicative of operating results for a future period and operating results for an interim period are not necessarily indicative of operating results for an entire year.

An extended disruption in services provided by third parties, including third-party regional carriers, could have a material adverse effect on our results of operations.

We utilize the services of third parties in a number of areas in support of our operations that are integral to our business, including third-party carriers in the Delta Connection program. While we have agreements with these providers that define expected service performance, we do not have direct control over their operations. In particular, some third-party regional carriers are facing a shortage of qualified pilots due to government mandated increases in flight experience required for pilots working for airlines. If this shortage becomes more widespread, third-party regional carriers may not be able to comply with their obligations to us. To the extent that a significant disruption in services occurs because third party providers, including regional carriers, are unable to perform their obligations over an extended period of time, our revenue may be reduced or our expenses may be increased resulting in a material adverse effect on our results of operations.



The failure or inability of insurance to cover a significant liability related to an environmental or other incident associated with the operation of the Monroe refinery could have a material adverse effect on our consolidated financial results.

Monroe’s refining operations are subject to various hazards unique to refinery operations, including explosions, fires, toxic emissions and natural catastrophes. Monroe could incur substantial losses, including cleanup costs, fines and other sanctions and third-party claims, and its operations could be interrupted, as a result of such an incident. Monroe’s insurance coverage does not cover all potential losses, costs or liabilities, and Monroe could suffer losses for uninsurable or uninsured risks or in amounts greater than its insurance coverage. In addition, Monroe’s ability to obtain and maintain adequate insurance may be affected by conditions in the insurance market over which it has no control. If Monroe were to incur a significant liability for which it is not fully insured or for which insurance companies do not or are unable to provide coverage, this could have a material adverse effect on our consolidated financial results of operations or consolidated financial position.

The operation of the refinery by Monroe is subject to significant environmental regulation. Failure to comply with environmental regulations or the enactment of additional regulation could have a negative impact on our consolidated financial results.

Monroe’s operations are subject to extensive environmental, health and safety laws and regulations, including those relating to the discharge of materials into the environment, waste management, pollution prevention measures and greenhouse gas emissions. Monroe could incur fines and other sanctions, cleanup costs and third-party claims as a result of violations of or liabilities under environmental, health and safety requirements, which if significant, could have a material adverse effect on our financial results. In addition, the enactment of new environmental laws and regulations, including any laws or regulations relating to greenhouse gas emissions, could significantly increase the level of expenditures required for Monroe or restrict its operations.

In particular, under the Energy Independence and Security Act of 2007, the EPA has adopted RFS that mandate the blending of renewable fuels into Transportation Fuels. RINs are assigned to renewable fuels produced or imported into the U.S. that are blended into Transportation Fuels to demonstrate compliance with this obligation. A refinery may meet its obligation under RFS by blending the necessary volumes of renewable fuels with Transportation Fuels or by purchasing RINs in the open market or through a combination of blending and purchasing RINs.

Because the refinery operated by Monroe does not blend renewable fuels, it must purchase its RINs requirement in the secondary market or obtain a waiver from the EPA. As a result, Monroe is exposed to the market price of RINs. Market prices for RINs have been volatile, marked by periods of sharp increases and decreases. We cannot predict the future prices of RINs. Purchasing RINs at elevated prices could have a material impact on our results of operations and cash flows.

Existing laws or regulations could change, and the minimum volumes of renewable fuels that must be blended with refined petroleum products may increase. Increases in the volume of renewable fuels that must be blended into Monroe's products could limit the refinery's production if sufficient numbers of RINs are not available for purchase or relief from this requirement is not obtained, which could have an adverse effect on our consolidated financial results.

If we lose senior management and other key employees and they are not replaced by individuals with comparable skills, our operating results could be adversely affected.

We are dependent on the experience and industry knowledge of our officers and other key employees to design and execute our business plans. If we experience a substantial turnover in our leadership and other key employees, and these persons are not replaced by individuals with comparable skills, our performance could be materially adversely impacted. Furthermore, we may be unable to attract and retain additional qualified executives as needed in the future.

Our reputation and brand could be damaged if we are exposed to significant adverse publicity through social media.

We operate in a highly visible, public environment with significant exposure to social media. Adverse publicity, whether justified or not, can rapidly spread through social or digital media. In particular, passengers can use social media to provide feedback about their interaction with us in a manner that can be quickly and broadly disseminated. To the extent we are unable to respond timely and appropriately to adverse publicity, our brand and reputation may be damaged. Significant damage to our overall reputation and brand image could have a negative impact on our financial results.



## Risk Factors Relating to the Airline Industry

Terrorist attacks, geopolitical conflict or security events may adversely affect our business, financial condition and operating results.

Terrorist attacks, geopolitical conflict or security events, or fear of such events, could have a significant adverse effect on our business. Despite significant security measures at airports and airlines, the airline industry remains a high profile target for terrorist groups. We constantly monitor threats from terrorist groups and individuals, including from violent extremists both internationally and domestically, with respect to direct threats against our operations and in ways not directly related to the airline industry. In addition, the impact on our operations of avoiding areas of the world, including airspace, in which there are geopolitical conflicts and the targeting of commercial aircraft by parties to those conflicts can be significant. Security events, primarily from external sources but also from potential insider threats, also pose a significant risk to our passenger and cargo operations. These events could include random acts of violence and could occur in public areas that we cannot control.

Terrorist attacks, geopolitical conflict or security events, or fear of such events, even if not made directly on or involving the airline industry, could have significant negative impact on us by discouraging passengers from flying, leading to decreased ticket sales and increased refunds. In addition, potential costs from these types of events include increased security costs, impacts from avoiding flight paths over areas in which conflict is occurring, reputational harm and other costs. If any or all of these types of events occur, they could have a material adverse effect on our business, financial condition and results of operations.

The global airline industry is highly competitive and, if we cannot successfully compete in the marketplace, our business, financial condition and operating results will be materially adversely affected.

The airline industry is highly competitive, marked by significant competition with respect to routes, fares, schedules (both timing and frequency), services, products, customer service and frequent flyer programs. Consolidation in the airline industry, the rise of well-funded government sponsored international carriers, changes in international alliances and the creation of immunized joint ventures have altered and will continue to alter the competitive landscape in the industry, resulting in the formation of airlines and alliances with increased financial resources, more extensive global networks and competitive cost structures.

Our domestic operations are subject to competition from traditional network carriers, including American Airlines and United Airlines, national point-to-point carriers, including Alaska Airlines, JetBlue Airways and Southwest Airlines, and discount carriers, some of which may have lower costs than we do and provide service at low fares to destinations served by us. Point-to-point, discount and ultra low-cost carriers, including Spirit Airlines and Allegiant Air, place significant competitive pressure on network carriers in the domestic market. As a result, we face significant competition at our domestic hub and gateway airports either directly at those airports or at the hubs of other airlines that are located in close proximity to our hubs and gateways. We also face competition in smaller to medium-sized markets from regional jet operations of other carriers. Our ability to compete in the domestic market effectively depends, in part, on our ability to maintain a competitive cost structure. If we cannot maintain our costs at a competitive level, then our business, financial condition and operating results could be materially adversely affected.

Our international operations are subject to competition from both foreign and domestic carriers. Competition is significant from government-owned and -funded carriers in the Gulf region, including Emirates, Etihad Airways and Qatar Airways. These carriers have large numbers of international widebody aircraft on order and are increasing service to the U.S. from their hubs in the Middle East. Several of these carriers, along with carriers from China, India and Southeast Asia, are government-subsidized, which has allowed them to grow quickly, reinvest in their product and expand their global presence at the expense of U.S. airlines.

Through alliance and other marketing and codesharing agreements with foreign carriers, U.S. carriers have increased their ability to sell international transportation, such as services to and beyond traditional European and Asian gateway cities. Similarly, foreign carriers have obtained increased access to interior U.S. passenger traffic beyond traditional U.S. gateway cities through these relationships. In addition, several joint ventures among U.S. and foreign carriers have received grants of antitrust immunity allowing the participating carriers to coordinate schedules, pricing, sales and inventory.

Increased competition in both the domestic and international markets may have a material adverse effect on our business, financial condition and operating results.

Extended interruptions or disruptions in service at major airports in which we operate could have a material adverse impact on our operations.

The airline industry is heavily dependent on business models that concentrate operations in major airports in the United States and throughout the world. An extended interruption or disruption at an airport where we have significant operations could have a material impact on our business, financial condition and results of operation.

The airline industry is subject to extensive government regulation, and new regulations may increase our operating costs.

Airlines are subject to extensive regulatory and legal compliance requirements that result in significant costs. For instance, the FAA from time to time issues directives and other regulations relating to the maintenance and operation of aircraft that necessitate significant expenditures. We expect to continue incurring significant expenses to comply with the FAA's regulations.

Other laws, regulations, taxes and airport rates and charges have also been imposed from time to time that significantly increase the cost of airline operations or reduce revenues. The industry is heavily taxed. For example, the Aviation and Transportation Security Act mandates the federalization of certain airport security procedures and imposes security requirements on airports and airlines, most of which are funded by a per ticket tax on passengers and a tax on airlines. Additional taxes and fees, if implemented, could negatively impact our results of operations.

Proposals to address congestion issues at certain airports or in certain airspace, particularly in the Northeast U.S., have included concepts such as "congestion-based" landing fees, "slot auctions" or other alternatives that could impose a significant cost on the airlines operating in those airports or airspace and impact the ability of those airlines to respond to competitive actions by other airlines. In addition, the failure of the federal government to upgrade the U.S. air traffic control system has resulted in delays and disruptions of air traffic during peak travel periods in certain congested markets. The failure to improve the air traffic control system could lead to increased delays and inefficiencies in flight operations as demand for U.S. air travel increases, having a material adverse effect on our operations. Failure to update the air traffic control system in a timely manner, and the substantial funding requirements of an updated system that may be imposed on air carriers, may have an adverse impact on our financial condition and results of operations.

Future regulatory action concerning climate change, aircraft emissions and noise emissions could have a significant effect on the airline industry. While the specific nature of future actions is hard to predict, new environmental laws or regulations adopted in the U.S. or other countries could impose significant additional costs on our operations, either through direct costs in our operations or through increases in costs that our suppliers pass along to us.

We and other U.S. carriers are subject to domestic and foreign laws regarding privacy of passenger and employee data that are not consistent in all countries in which we operate. In addition to the heightened level of concern regarding privacy of passenger data in the U.S., certain European government agencies are reviewing airline privacy practices. Compliance with these regulatory regimes is expected to result in additional operating costs and could impact our operations and any future expansion.

Prolonged periods of stagnant or weak economic conditions could have a material adverse effect on our business, financial condition and operating results.

As a result of the discretionary nature of air travel, the airline industry has been cyclical and particularly sensitive to changes in economic conditions. Because we operate globally, with approximately 30% of our revenues from operations outside of the U.S., our business is subject to economic conditions throughout the world. During periods of unfavorable or volatile economic conditions in the global economy, demand for air travel can be significantly impacted as business and leisure travelers choose not to travel, seek alternative forms of transportation for short trips or conduct business through videoconferencing. If unfavorable economic conditions occur, particularly for an extended period, our business, financial condition and results of operations may be adversely affected. In addition, significant or volatile changes in exchange rates between the U.S. dollar and other currencies, and the imposition of exchange controls or other currency restrictions, may have a material adverse effect on our liquidity, financial conditions and results of operations.



## Table of Contents

Economic conditions and regulatory changes leading up to and following the United Kingdom’s exit from the European Union could have a material adverse effect on our business and results of operations.

Following a referendum in June 2016 in which voters in the U.K. approved an exit from the European Union ("EU"), the U.K. government has initiated a process to leave the EU (often referred to as Brexit) and begun negotiating the terms of the U.K.'s future relationship with the EU. The airline industry faces substantial uncertainty regarding the impact of the exit of the U.K. from the EU. Adverse consequences such as deterioration in economic conditions, volatility in currency exchange rates or adverse changes in regulation of the airline industry or bilateral agreements governing air travel could have a negative impact on our operations, financial condition and results of operations.

The rapid spread of contagious illnesses can have a material adverse effect on our business and results of operations.

The rapid spread of a contagious illness, or fear of such an event, can have a material adverse effect on the demand for worldwide air travel and therefore have a material adverse effect on our business and results of operations. Moreover, our operations could be negatively affected if employees are quarantined as the result of exposure to a contagious illness. Similarly, travel restrictions or operational issues resulting from the rapid spread of contagious illnesses in a part of the world in which we have significant operations may have a materially adverse impact on our business and results of operations.

## Ground Facilities

## Airline Operations

We lease most of the land and buildings that we occupy. Our largest aircraft maintenance base, various computer, cargo, flight kitchen and training facilities and most of our principal offices are located at or near the Atlanta airport on land leased from the City of Atlanta. We lease ticket counters, passenger holdrooms, operating areas and other terminal space in most of the airports that we serve. At most airports, we have entered into use agreements which provide for the non-exclusive use of runways, taxiways and other improvements and facilities; landing fees under these agreements normally are based on the number of landings and weight of aircraft. These leases and use agreements generally run for periods of less than one year to 30 years or more, and often contain provisions for periodic adjustments of lease rates, landing fees and other charges applicable under that type of agreement. We also lease aircraft maintenance and air cargo facilities at several airports. Our facility leases generally require us to pay the cost of providing, operating and maintaining such facilities, including, in some cases, amounts necessary to pay debt service on special facility bonds issued to finance their construction. We also lease marketing offices, reservations offices and other off-airport facilities in certain locations for varying terms.

We own our Atlanta reservations center, other real property in Atlanta, and reservations centers in Minot, North Dakota and Chisholm, Minnesota.

## Refinery Operations

Our wholly owned subsidiaries, Monroe and MIPC, own and operate the Trainer refinery and related assets in Pennsylvania. The facility includes pipelines and terminal assets that allow the refinery to supply jet fuel to our airline operations throughout the Northeastern U.S., including our New York hubs at LaGuardia and JFK.

## ITEM 3. LEGAL PROCEEDINGS

## First Bag Fee Antitrust Litigation

In 2009, a number of purported class action antitrust lawsuits were filed against Delta and AirTran Airways ("AirTran"), alleging that Delta and AirTran engaged in collusive behavior in violation of Section 1 of the Sherman Act in November 2008 based upon certain public statements made in October 2008 by AirTran's CEO at an analyst conference concerning fees for the first checked bag, Delta's imposition of a fee for the first checked bag on November 4, 2008 and AirTran's imposition of a similar fee on November 12, 2008. The plaintiffs sought to assert claims on behalf of an alleged class consisting of passengers who paid the first bag fee after December 5, 2008 and seek injunctive relief and unspecified treble damages. All of these cases have been consolidated for pre-trial proceedings and remain pending in the Northern District of Georgia.

On July 12, 2016, the Court issued an order granting the plaintiffs' motion for class certification. On October 7, 2016, the U.S. Court of Appeals for the Eleventh Circuit granted the defendants' petition for interlocutory review of this order, and that appeal remains pending.

On March 29, 2017, the District Court granted the defendants' motions for summary judgment. The plaintiffs have filed an appeal to the U.S. Court of Appeals, and that appeal remains pending.

## Capacity Antitrust Litigation

In July 2015, a number of purported class action antitrust lawsuits were filed alleging that Delta, American, United and Southwest had conspired to restrain capacity. The lawsuits were filed in the wake of media reports that the U.S. Department of Justice had served civil investigative demands upon these carriers seeking documents and information relating to this subject. The lawsuits have been consolidated into a single Multi-District Litigation proceeding in the U.S. District Court for the District of Columbia. In November 2016, the District Court denied the defendants' motion to dismiss the claims, and the matter is now proceeding through discovery. Delta believes the claims in these cases are without merit and is vigorously defending these lawsuits.

As reflected above, the Board has increased the quarterly dividend payment several times, most recently to $0.305 per share in the September 2017 quarter. The Board expects to be able to continue to pay cash dividends for the foreseeable future, subject to applicable limitations under Delaware law. Dividend payments will be dependent upon our results of operations, financial condition, cash requirements, future prospects and other factors deemed relevant by the Board of Directors. In addition, our ability to pay future dividends is subject to compliance with covenants in several of our credit facilities.



## Stock Performance Graph

The following graph compares the cumulative total returns during the period from December 31, 2012 to December 31, 2017 of our common stock to the Standard & Poor's 500 Stock Index and the NYSE ARCA Airline Index. The comparison assumes $100 was invested on December 31, 2012 in each of our common stock and the indices and assumes that all dividends were reinvested.



## Issuer Purchases of Equity Securities

The following table presents information with respect to purchases of common stock we made during the December 2017 quarter. The total number of shares purchased includes shares repurchased pursuant to our $5 billion share repurchase program, which was publicly announced on May 11, 2017 and will terminate no later than December 31, 2020. Some purchases were made pursuant to a trading plan meeting the requirements of Rule 10b5-1 under the Securities Exchange Act of 1934.

In addition, the table includes shares withheld from employees to satisfy certain tax obligations due in connection with grants of stock under the Delta Air Lines, Inc. Performance Compensation Plan (the "Plan"). The Plan provides for the withholding of shares to satisfy tax obligations. It does not specify a maximum number of shares that can be withheld for this purpose. The shares of common stock withheld to satisfy tax withholding obligations may be deemed to be "issuer purchases" of shares that are required to be disclosed pursuant to this Item.

## ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

## Financial Highlights - 2017 Compared to 2016

Our pre-tax income for 2017 was $5.7 billion, representing a $935 million decrease compared to the prior year primarily due to higher fuel costs, salaries and related costs and depreciation expense, which were partially offset by increased operating revenue. Pre-tax income, adjusted for special items (a non-GAAP financial measure) was $5.5 billion, a decrease of $621 million, or 10.2%. Special items were primarily related to fuel hedge MTM adjustments and settlements of $259 million in 2017 compared to $450 million in 2016.

Revenue. Compared to 2016, our operating revenue increased $1.6 billion, or 4.0%, on 1.0% higher capacity combined with robust demand and strong revenue momentum, closing 2017 with three consecutive quarters of year-over-year passenger unit revenue growth. Passenger revenue per available seat mile ("PRASM") increased 2.1% led by (1) strong domestic leisure yields, (2) expanded distribution of Branded Fares, (3) an improving business fare environment, (4) strength in the Atlantic region leveraged through U.S. point-of-sale traffic gains, along with business cabin traffic and yield growth, and (5) strong performance in the Caribbean, Central America, Brazil and Mexico leisure markets. Other revenue increased 9.7% partially resulting from growth in our co-brand credit card partnership with American Express.

Operating Expense. Total operating expense increased $2.4 billion and our consolidated operating cost per available seat mile ("CASM") increased 6.4% compared to 2016 to 13.81 cents, primarily due to higher fuel costs, salaries and related costs and depreciation expense. Including our regional carriers, fuel expense increased $771 million compared to the prior year due to a 22.3% increase in the market price per gallon of fuel, partially offset by reduced fuel hedge losses compared to the prior year and profits generated within our refinery segment. Salaries and related costs were higher due to increases for eligible merit, ground and flight attendant employees implemented in the June 2017 quarter. The increase in depreciation expense primarily results from new aircraft deliveries, including B-737-900ER, A321-200, A330-300 and A350-900 aircraft, fleet modifications and accelerated depreciation due to the planned retirement of our MD-88 fleet and two B-767-300ER aircraft.

Non-fuel unit costs ("CASM-Ex, including profit sharing" a non-GAAP financial measure) increased 4.3% to 10.57 cents due to the pay rate increases and depreciation expense discussed above, which were partially offset by productivity gains from our fleet, technology and supply chain initiatives.

The non-GAAP financial measures for pre-tax income, adjusted for special items, and CASM-Ex, including profit sharing, both used above, are defined and reconciled in "Supplemental Information" below.

Passenger revenue increased $1.0 billion over the prior year. PRASM increased 2.1% and passenger mile yield increased 0.9% on 1.0% higher capacity. Load factor was 1.0 point higher than the prior year at 85.6% .

Unit revenues of the domestic region increased 1.7%, resulting from our commercial initiatives, including differentiated products for our customers, known as Branded Fares, and an improving revenue environment. We continue to differentiate our product offerings and enable customer choice through segmentation, including offering Basic Economy throughout our domestic network. Our domestic operations closed 2017 with three consecutive quarters of year-over-year unit revenue growth, with robust demand for both business and leisure. We continue to see improvements in business markets with 81 of the top 100 business markets producing positive yields during the December 2017 quarter, up from 50% from earlier in the year.

Passenger revenues related to our international regions increased 0.5% year-over-year primarily due to strength in the Atlantic and Latin America regions, partially offset by revenue declines in the Pacific. During 2017, we continued to roll out the expansion of our Branded Fares product throughout the international regions.

The Atlantic region closed 2017 with three consecutive quarters of year-over-year unit revenue growth on strong business class bookings. We continue to leverage our alliance partners' hub positions in Europe's leading business markets of London, Amsterdam and Paris to increase the volume of U.S. point-of-sale traffic. The U.K. was particularly robust, with unit revenue growth throughout 2017, including double-digit growth in the second half of 2017. During the year, we expanded our Basic Economy product to mitigate the impact of ultra-low cost carrier capacity increases.

Unit revenue declines in the Pacific primarily resulted from industry capacity growth in the region. We continued to optimize the Pacific region with a 7.7% reduction in capacity during 2017, focused on refining the network to generate incremental value from our Chinese and Korean alliances and differentiating our product offerings, including expanding Basic Economy and selling Comfort+ as a separate fare product. During 2017, we reached an agreement to create a trans-Pacific joint venture with Korean Air, offering an enhanced and expanded network, industry-leading products and service, and a seamless customer experience between the U.S. and Asia. We also retired our last B-747-400 and introduced our new A350-900 with Delta One suites and the Delta Premium Select cabin on routes from Detroit to Tokyo-Narita and Seoul-Incheon, which are driving improvements in both profitability and customer feedback. These efforts are beginning to show results as the Pacific returned to positive PRASM growth during the December 2017 quarter for the first time in more than four years.

Unit revenues increased in Latin America principally resulting from unit revenue improvement in Brazil, related to both improved traffic and higher fares. This improvement was driven by the strengthening of the Brazilian economy and additional connectivity for our customers provided by our relationship with GOL. Increased leisure traffic to Mexico and the Caribbean, and the incremental value provided by our alliance with Aeroméxico also contributed to the Latin America unit revenue improvement. Although unit revenue improved in the Caribbean, hurricane damage in several markets during 2017 resulted in temporary service adjustments. Finally, we continued to differentiate our product offerings, including expanding Basic Economy and selling Comfort+ as a separate fare product in Latin America.

Loyalty programs. We sell mileage credits to credit card companies, hotels and car rental agencies under marketing agreements. We allocate the consideration received from mileage credit sales to the individual products and services bundled with the sale based on their relative selling prices. We defer the travel component as part of frequent flyer deferred revenue and recognize passenger revenue as the mileage credits are redeemed for travel. The revenue allocated to the remaining deliverables (such as lounge access, baggage fee waivers and brand usage) is recorded in other revenue. We recognize the revenue for these services as they are performed.

The amount of loyalty program revenue changes based on the price paid for mileage credits, the volume of credits sold and our allocation of selling price to the individual products and services. With the adoption of the new revenue recognition standard in 2018, we will increase the value we use to account for the travel component within mileage credit sales. This new value for the travel component will cause a re-allocation of the consideration received from mileage credit sales. The re-allocation will result in less revenue recognized for loyalty programs in other revenue and more revenue in passenger revenue as the frequent flyer awards are redeemed.

Loyalty program revenue increased compared to 2016 related to growth in our co-brand credit card partnership with American Express. Additional information about our frequent flyer program accounting policies can be found in Note 1 of the Notes to the Consolidated Financial Statements.

Administrative fees, club and on-board sales. These revenues primarily relate to travel-related services such as ticket changes and unaccompanied minors and also include amounts collected for on-board sales and Sky Club lounge memberships. We recognize revenue as these services are performed. A significant portion of these fees are travel-related and performed in conjunction with the passenger’s flight. Therefore, the majority of these fees will be reclassified to passenger revenue with our adoption of the new revenue recognition standard in 2018.

Ancillary businesses and refinery. Ancillary businesses and refinery includes aircraft maintenance and staffing services we provide to third parties, our vacation wholesale operations and refinery sales to third parties. Ancillary businesses and refinery revenues are not related to the generation of a seat mile. Ancillary businesses and refinery sales primarily increased due to sales of non-jet fuel products to third parties by our oil refinery, consistent with stronger pricing of refined products throughout the oil industry.

Baggage fees. The revenue amount shown above represents baggage fees that were sold as a separate component of the passenger’s ticket. Similar to administrative fees described above, baggage services are performed and earned in conjunction with the passenger’s flight, and these fees will be reclassified to passenger revenue with our adoption of the new revenue recognition standard in 2018.

Salaries and Related Costs. The increase in salaries and related costs is primarily due to increases for eligible merit, ground and flight attendant employees implemented in the June 2017 quarter.

Aircraft Fuel and Related Taxes. Including our regional carriers, fuel expense increased $771 million compared to the prior year due to a 22.3% increase in the market price per gallon of fuel, partially offset by reduced fuel hedge losses compared to the prior year and profits generated within our refinery segment. The table below presents fuel expense, including our regional carriers:

Depreciation and Amortization. The increase in depreciation expense primarily results from new aircraft deliveries, including B-737-900ER, A321-200, A330-300 and A350-900 aircraft, fleet modifications and accelerated depreciation due to the planned retirement of our MD-88 fleet and two B-767-300ER aircraft.

Contracted Services. The increase in contracted services expense predominantly relates to additional contract labor expenses associated with investments in our technology infrastructure and other activities to improve the customer experience.

Aircraft Maintenance Materials and Outside Repairs. Aircraft maintenance materials and outside repairs consist of costs associated with the maintenance of aircraft used in our operations and costs associated with maintenance sales to third parties by our MRO business. The increase in aircraft maintenance materials and outside repairs expense primarily relates to an increase in maintenance activity in order to enhance service reliability of certain aircraft.

Passenger Service. Passenger service expense includes the costs of onboard food and beverage, cleaning and supplies. The increase in passenger service expense predominantly relates to costs associated with enhancements to our onboard product offering and higher traffic.

Aircraft Rent. The increase in aircraft rent primarily results from new leased aircraft deliveries since the prior year, including B-737-900ER and A321-200 aircraft.

Other. The increase in other expense primarily relates to costs associated with sales of non-jet fuel products to third parties by our oil refinery.

Passenger revenue decreased $1.0 billion over the prior year. PRASM decreased 4.9% and passenger mile yield decreased 4.5% on 2.1% higher capacity. Load factor was 0.3 points lower than the prior year at 84.6%.

Unit revenues of the domestic region decreased 5.2%, resulting from weakness in the close-in yield environment during most of the year despite strong volume.

Revenues related to our international regions decreased 7.2% year-over-year primarily due to yield declines resulting from imbalances between supply and demand, principally in the Atlantic region and China, the impact of foreign currency fluctuations, continued reductions in international fuel surcharges and economic challenges in certain regions.

In the Atlantic, the unit revenue decline predominantly resulted from lower yields driven by industry capacity growth outpacing passenger demand and the strength of the U.S. dollar. In core European markets, U.S. point-of-sale demand was strong and recovered quickly following the Brussels airport terrorist attack in March 2016. However, Europe point-of-sale demand was soft largely due to the impact of weaker Euro exchange rates.

Unit revenue declines in the Pacific compared to 2015 primarily resulted from lower yen hedge gains, lower international fuel surcharges and yield declines resulting from industry capacity growth between the U.S. and China. During the September 2016 quarter, the U.S. Department of Transportation announced that we were awarded two daytime slot pairs at Tokyo's Haneda Airport (from Los Angeles and Minneapolis). We commenced these routes and canceled other routes in the Pacific region during the December 2016 quarter as part of our ongoing optimization of the Pacific region.

Although Latin America unit revenues declined compared to 2015, unit revenues improved in the second half of 2016 compared to the second half of 2015. An Open Skies agreement between the U.S. and Mexico took effect in August 2016 and our application for antitrust immunity with Aeroméxico was approved in the December 2016 quarter, which continued to strengthen our performance in the important Mexican business markets.

## Cargo Revenue

Cargo revenue decreased $145 million, or 17.8%, primarily due to weaker international demand compared to the prior year.

Salaries and Related Costs. The increase in salaries and related costs was principally due to pay rate increases given to eligible employees, which includes an 18% pay rate increase for pilots resulting from a new pilot contract ratified in the December 2016 quarter that was retroactive to January 1, 2016. Additionally, in the December 2015 quarter, base pay rates increased 14.5% for eligible merit, ground and flight attendant employees in conjunction with changes in their profit sharing program.



Aircraft Fuel and Related Taxes. Including our regional carriers, fuel expense decreased $1.6 billion compared to the prior year due to an 18% decrease in the market price per gallon of fuel and lower fuel hedge losses, partially offset by a loss from our refinery segment in the current year compared to a profit in the prior year and a 0.7% increase in consumption.

The table below presents fuel expense, including our regional carriers:

(3) MTM adjustments and settlements include the effects of the derivative transactions discussed in Note 4 of the Notes to the Consolidated Financial Statements. For additional information and the reason for adjusting fuel expense, see "Supplemental Information" below.

Regional Carriers Expense. The increase in regional carriers expense was primarily due to increases in aircraft maintenance and scheduled contract carrier rate escalations, partially offset by lower fuel cost from the decrease in the market price of fuel.

Contracted Services. The increase in contracted services expense predominantly related to costs associated with the 2.1% increase in capacity and additional temporary staffing.

Profit Sharing. The decrease in profit sharing was primarily due to an adjustment to the profit sharing calculation during 2016 (paid out in 2017) for merit, ground and flight attendant employees. This adjusted calculation paid 10% of annual profit (as defined by the terms of the program) and, if we exceeded our prior-year results, the program paid 20% of the year-over-year increase in profit to eligible employees. In 2015, our profit sharing program paid 10% to all eligible employees for the first $2.5 billion of annual profit and 20% of annual profit above $2.5 billion. The profit sharing program for pilots remained unchanged from the prior year.

At December 31, 2016, the principal amount of debt and capital leases was $7.4 billion. During 2017, we issued $2.5 billion of unsecured notes. As a result of the debt issuances, partially offset by scheduled principal payments, the amount of debt and capital leases was $8.9 billion at December 31, 2017.

Miscellaneous, net is primarily composed of our proportionate share of earnings from our equity investments in Virgin Atlantic and Grupo Aeroméxico, foreign exchange gains/losses and charitable contributions. Our equity investment earnings and foreign exchange gains/losses vary and impact the comparability of miscellaneous, net from period to period.

## Income Taxes

Our effective tax rate for 2017 was 37.2% . We recorded a provisional estimate of $150 million related to the Tax Cuts and Jobs Act of 2017, resulting in a 2.6% increase to our effective tax rate. We expect our annual effective tax rate to be between 21% and 23% for 2018. At December 31, 2017, we had approximately $5.1 billion of U.S. federal pre-tax net operating loss carryforwards, which do not begin to expire until 2027. Accordingly, we believe we will not pay cash federal income taxes before 2019. See Note 11 of the Notes to the Consolidated Financial Statements for more information.

## Refinery Segment

The refinery primarily produces gasoline, diesel and jet fuel. Monroe exchanges the non-jet fuel products the refinery produces with third parties for jet fuel consumed in our airline operations. The jet fuel produced and procured through exchanging gasoline and diesel fuel produced by the refinery provided approximately 200,000 barrels per day for use in our airline operations during 2017. We believe that the jet fuel supply resulting from the refinery's operation has contributed to the reduction in the market price of jet fuel, and thus lowered our cost of jet fuel compared to what it otherwise would have been.

The refinery recorded operating revenues of $5.0 billion in 2017, compared to $3.8 billion in 2016. Operating revenues in 2017 were primarily composed of $3.2 billion of non-jet fuel products exchanged with third parties to procure jet fuel and $886 million of sales of jet fuel to the airline segment. Refinery revenues increased compared to the prior year due to higher product demand and an increase in margins during the second half of 2017 due to hurricanes that caused extensive refinery closures on the Gulf Coast for several weeks.

The refinery recorded income of $110 million in 2017, compared to a loss of $125 million recorded in 2016. The refinery's income in 2017 was primarily due to higher refined product cracks, lower crude costs and higher throughput levels.

A refinery is subject to annual EPA requirements to blend renewable fuels into the gasoline and on-road diesel fuel it produces. Alternatively, a refinery may purchase renewable energy credits, called RINs, from third parties in the secondary market. The refinery, operated by Monroe purchases the majority of its RINs requirement in the secondary market. We recognized $159 million and $171 million of expense related to the RINs requirement in 2017 and 2016, respectively. RINs expense decreased during 2017 primarily as a result of a slight decrease in the unit cost of RINs during 2017 after a significant increase in the unit cost of RINs during 2016.

The Monroe refinery is planning for a shutdown of approximately 60 days in the December 2018 quarter. This planned outage, called a turnaround, is in accordance with the long term maintenance plan for the facility to allow for the safe completion of major repairs and upgrades. During that planned outage, we have identified other sources of fuel to maintain service levels and to mitigate the financial impact.

For more information regarding the refinery's results, see Note 14 of the Notes to the Consolidated Financial Statements.

## Financial Condition and Liquidity

We expect to meet our cash needs for the next 12 months from cash flows from operations, cash and cash equivalents, short-term investments and financing arrangements. As of December 31, 2017, we had $5.1 billion in unrestricted liquidity, consisting of $2.6 billion in cash and cash equivalents and short-term investments and $2.5 billion in undrawn revolving credit facilities. During 2017, we used existing cash and cash generated from operations to fund capital expenditures of $3.9 billion, purchase shares of Grupo Aeroméxico and Air France-KLM for $1.2 billion and return $2.4 billion to shareholders. In addition, we used the proceeds from a debt offering and cash generated from operations to contribute $3.2 billion in cash to fund our pension obligation.

## Sources of Liquidity

## Operating Activities

Cash flows from operating activities continue to provide our primary source of liquidity. We generated positive cash flows from operations of $5.1 billion in 2017, $7.2 billion in 2016 and $7.9 billion in 2015. We also expect to generate positive cash flows from operations in 2018. We had lower operating cash flows in 2017 compared to prior years primarily due to incremental pension plan contributions partially funded through $2.0 billion of debt issuance.

Our operating cash flows can be impacted by the following factors:

Seasonality of Advance Ticket Sales. We sell tickets for air travel in advance of the customer's travel date. When we receive a cash payment at the time of sale, we record the cash received on advance sales as deferred revenue in air traffic liability. The air traffic liability increases during the winter and spring as advanced ticket sales grow prior to the summer peak travel season and decreases during the summer and fall months.

Fuel. Including our regional carriers, fuel expense represented 19.2% of our total operating expenses for 2017. The market price for jet fuel is highly volatile, which can impact the comparability of our cash flows from operations from period to period.

Pension Contributions. We sponsor defined benefit pension plans for eligible employees and retirees. These plans are closed to new entrants and are frozen for future benefit accruals. Our funding obligations for these plans are governed by the Employee Retirement Income Security Act, as modified by the Pension Protection Act of 2006. In the first half of 2017, we contributed $3.5 billion to our qualified defined benefit pension plans using net proceeds from a $2.0 billion debt issuance, shares of our common stock from treasury with a value of $350 million and existing cash. As a result of these contributions, we satisfied, on an accelerated basis, our 2017 required contributions for our defined benefit plans, including more than $3.0 billion above the minimum funding requirements. We contributed $1.3 billion and $1.2 billion in 2016 and 2015, respectively. We have no minimum funding requirements in 2018. However, in January 2018, we voluntarily contributed approximately $500 million to these plans.

Profit Sharing. Our broad-based employee profit sharing program provides that, for each year in which we have an annual pre-tax profit, as defined by the terms of the program, we will pay a specified portion of that profit to employees. In determining the amount of profit sharing, the program defines profit as pre-tax profit adjusted for profit sharing and certain other items.

We paid $1.1 billion in February 2017, $1.5 billion in February 2016, and $1.1 billion in two payments, $756 million in February 2015 and more than $300 million in October 2014, to our employees in recognition of their contributions toward meeting our financial goals. During the year ended December 2017, we recorded $1.1 billion in profit sharing expense based on 2017 pre-tax profit, which was paid to employees in February 2018.

Effective October 1, 2017, we aligned our profit sharing plans under a single formula. Under this formula, our profit sharing program pays 10% to all eligible employees for the first $2.5 billion of annual profit and 20% of annual profit above $2.5 billion. Prior to that time, the profit sharing program for pilots used this formula but for 2016 and the first nine months of 2017, the profit sharing program for merit, ground and flight attendant employees paid 10% of annual profit (as defined by the terms of the program) and, if we exceeded our prior-year results, the program paid 20% of the year-over-year increase in profit to eligible employees. For years prior to 2016, the profit sharing program for merit, ground and flight attendant employees paid according to the current formula. Going forward, all eligible employees will be paid profit sharing under the current formula.

## Investing Activities

Capital Expenditures. Our capital expenditures were $3.9 billion in 2017, $3.4 billion in 2016 and $2.9 billion in 2015. Our capital expenditures during 2017 were primarily related to the purchase of B-737-900ER aircraft to replace a portion of our older B-757-200 aircraft, purchases of A321-200 and A330-300 aircraft, advanced deposit payments on future aircraft order commitments and seat density projects for our domestic fleet. Our capital expenditures during 2016 and 2015 were primarily for the purchase of aircraft and modifications to upgrade aircraft interiors that enhance our product offering.

We have committed to future aircraft purchases that will require significant capital investment and have obtained long-term financing commitments for a substantial portion of the purchase price of these aircraft. We expect that we will invest approximately $4.5 billion in 2018 primarily for (1) aircraft, including deliveries of B-737-900ERs, A321-200s and A350-900s, along with advance deposit payments for these and our new A330-900neo and CS100 orders as well as for (2) aircraft modifications, the majority of which relate to increasing the seat density and enhancing the cabins on our domestic fleet. We expect that the 2018 investments will be funded primarily through cash flows from operations.

Equity Investments. During 2017, we completed a $622 million tender offer and settled derivative contracts for $173 million to obtain additional capital stock of Grupo Aeroméxico, increasing our ownership percentage to a non-controlling 49% equity stake in Grupo Aeroméxico. During the December 2017 quarter, we acquired shares of Air France-KLM for $450 million, which provides us with a 10% ownership interest.

Los Angeles International Airport Construction. During 2016, we executed a new lease agreement with Los Angeles World Airports ("LAWA"), which owns and operates LAX, and announced plans to modernize, upgrade and connect Terminals 2 and 3 at LAX over the next seven years. Based on the lease agreement, we are designing and managing the construction of the initial investment of $350 million to renovate gate areas, support space and other amenities for passengers, upgrade the baggage handling systems in the terminals and facilitate the relocation of those airlines located in Terminals 2 and 3 to Terminals 5 and 6 and Tom Bradley International Terminal ("TBIT"). The relocation activities were completed during the June 2017 quarter. Subject to required approvals, we have an option to expand the project, which could cost an additional $1.5 billion and would include (1) redevelopment of Terminal 3 and enhancement of Terminal 2, (2) rebuild of the ticketing, arrival hall and security checkpoint, (3) construction of infrastructure for the planned airport people mover, (4) ramp improvements and (5) construction of a secure connector to the north side of TBIT.

A substantial majority of the project costs will be funded through the Regional Airports Improvement Corporation ("RAIC"), a California public benefit corporation, using an $800 million revolving credit facility provided by a group of lenders. The credit facility was executed during 2017. Loans made under the credit facility will be repaid with the proceeds from LAWA's purchase of completed project assets. We have guaranteed the obligations of the RAIC under the credit facility. We expect to spend approximately $200 million on this project in 2018 using funding provided by the credit agreement and/or cash flows from operations.

New York-LaGuardia Redevelopment. As part of the terminal redevelopment project at LaGuardia Airport, we are partnering with the Port Authority of New York and New Jersey (the "Port Authority") to replace Terminals C and D with a new state-of-the-art terminal facility consisting of 37 gates across four concourses connected to a central headhouse. The terminal will feature a new, larger Delta Sky Club, wider concourses, more gate seating and 30 percent more concessions space than the existing terminals. The facility will also offer direct access between the parking garage and terminal and improved roadways and drop-off/pick-up areas. The design of the new terminal will integrate sustainable technologies and improvements in energy efficiency. Construction will be phased to limit passenger inconvenience and is expected to be completed by 2026.

In connection with the redevelopment, during 2017, we entered into an amended and restated terminal lease with the Port Authority with a term through 2050. Pursuant to the lease agreement we will (1) fund (through debt issuance and existing cash) and undertake the design, management and construction of the terminal and certain off-premises supporting facilities, (2) receive a Port Authority contribution of $600 million to facilitate construction of the terminal and other supporting infrastructure, (3) be responsible for all operations and maintenance during the term of the lease and (4) have preferential rights to all gates in the terminal subject to Port Authority requirements with respect to accommodation of designated carriers. We currently expect our costs for the project to be approximately $3.3 billion and we bear the risks of project construction, including if the project's actual costs exceed the projected costs. We expect to spend approximately $550 million on this project in 2018 using funding provided by cash flows from operations and/or financing arrangements.

## Financing Activities

Debt and Capital Leases. The principal amount of debt and capital leases was $8.9 billion at December 31, 2017. Since December 31, 2009, we have reduced our principal amount of debt and capital leases by $9.4 billion.

During the March 2017 quarter, we issued $2.0 billion in aggregate principal amount of unsecured notes, consisting of $1.0 billion of 2.785% Notes due 2020 and $1.0 billion of 3.625% Notes due 2022. As discussed above, we used the net proceeds from this issuance to make a cash contribution to our qualified defined benefit pension plans. During the December 2017 quarter, we issued $450 million in aggregate principal amount of 2.600% Notes due 2020.

Our Pacific Facilities (including the Term Loan with a principal balance of $1.0 billion) mature in October 2018. We expect to repay this obligation with cash flows from operations, cash and cash equivalents and/or new financing arrangements.

During 2017, we received an upgrade to our credit rating from Standard & Poor's to an investment-grade rating of BBB-. We now have investment-grade ratings from all three major credit rating agencies.

At December 31, 2017, our corporate ratings were:

<table><tr><td>Rating Agency</td><td>Current Rating</td><td>Outlook</td></tr><tr><td>Fitch</td><td>BBB-</td><td>Stable</td></tr><tr><td>Moody&#x27;s</td><td>Baa3</td><td>Stable</td></tr><tr><td>Standard &amp; Poor&#x27;s</td><td>BBB-</td><td>Stable</td></tr></table>

Capital Returns to Shareholders. Since first implementing our quarterly dividend in 2013, we have increased the dividend per share by 50% annually and paid $1.9 billion in total dividends, including $731 million in 2017. Through dividends and share repurchases, we have returned $9.8 billion to shareholders since 2013, while reducing outstanding shares by approximately 18% compared to the beginning of 2013. During 2017 alone, we repurchased and retired 33 million shares at a cost of $1.7 billion.

<table><tr><td>(in millions, except repurchase price)</td><td>Share Repurchase Authorization</td><td>Average Repurchase Price</td><td>Planned Completion Date</td><td>Authorization Remaining</td></tr><tr><td>May 2014 Program</td><td>$ 2,000</td><td>$ 42.86</td><td>December 31, 2016</td><td>Completed June 2015</td></tr><tr><td>May 2015 Program</td><td>$ 5,000</td><td>$ 45.32</td><td>December 31, 2017</td><td>Completed September 2017</td></tr><tr><td>May 2017 Program</td><td>$ 5,000</td><td>$ 52.13</td><td>December 31, 2020</td><td>$ 4,675</td></tr></table>

On February 9, 2018, the Board of Directors declared a $0.3050 per share dividend for shareholders of record as of February 23, 2018.

Fuel Hedge Restructuring. During 2016, we entered into transactions to defer settlement of a portion of our hedge portfolio until 2017. These deferral transactions, excluding market movements from the date of inception, provided approximately $300 million in cash receipts during the second half of 2016 and required approximately $300 million in cash payments in 2017.

During the June 2016 quarter, we early terminated certain of our outstanding deferral transactions and made cash payments of $170 million, including normal settlements. As a result, during the year ended December 31, 2017, we reported $20 million in cash receipts and $244 million in cash payments associated with these transactions. For additional information regarding these transactions, see Note 4 to the Notes to the Consolidated Financial Statements.

## Undrawn Lines of Credit

We have $2.5 billion available in undrawn revolving lines of credit. Our credit facilities have covenants, including minimum collateral coverage ratios. If we are not in compliance with these covenants, we may be required to repay amounts borrowed under the credit facilities or we may not be able to draw on them. We currently have a substantial amount of unencumbered assets available to pledge as collateral.

## Covenants

We were in compliance with the covenants in our financing agreements at December 31, 2017.



## Contractual Obligations

The following table summarizes our contractual obligations at December 31, 2017 that we expect will be paid in cash. The table does not include amounts that are contingent on events or other factors that are uncertain or unknown at this time, including legal contingencies, uncertain tax positions and amounts payable under collective bargaining arrangements, among others. In addition, the table does not include expected significant cash payments representing obligations that arise in the ordinary course of business that do not include contractual commitments.

The amounts presented 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 presented in the table.

## Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are those that require significant judgments and estimates. Accordingly, the actual results may differ materially from these estimates. For a discussion of these and other accounting policies, see Note 1 of the Notes to the Consolidated Financial Statements.

## Frequent Flyer Program

Our SkyMiles program offers incentives to travel on Delta. This program allows customers to earn mileage credits by flying on Delta, Delta Connection and airlines that participate in the SkyMiles program, as well as through participating companies such as credit card companies, hotels and car rental agencies. We sell mileage credits to non-airline businesses, customers and other airlines. Effective January 1, 2015, the SkyMiles program was modified from a model in which customers earn redeemable mileage credits based on distance traveled to a model based on ticket price. This award change did not affect the way we account for the program.

The SkyMiles program includes two types of transactions that are considered revenue arrangements with multiple deliverables. As discussed below, these are (1) passenger ticket sales earning mileage credits and (2) the sale of mileage credits to participating companies with which we have marketing agreements. Mileage credits are a separate unit of accounting as they can be redeemed by customers in future periods for air travel on Delta and participating airlines, membership in our Sky Club and other program awards.

Passenger Ticket Sales Earning Mileage Credits. Passenger ticket sales earning mileage credits under our SkyMiles program provide customers with (1) mileage credits earned and (2) air transportation. We value each deliverable on a standalone basis. Our estimate of the selling price of a mileage credit is based on an analysis of our sales of mileage credits to other airlines and customers, which is re-evaluated at least annually. We use established ticket prices to determine the estimated selling price of air transportation. We allocate the total amount collected from passenger ticket sales between the deliverables based on their relative selling prices.

We defer revenue for the mileage credits related to passenger ticket sales when the credits are earned and recognize it as passenger revenue when miles are redeemed and services are provided. We record the air transportation portion of the passenger ticket sales in air traffic liability and recognize these amounts in passenger revenue when we provide transportation or when the ticket expires unused. A hypothetical 10% increase in our estimate of the standalone selling price of a mileage credit would decrease passenger revenue by approximately $50 million, as a result of an increase in the amount of revenue deferred from the mileage component of passenger ticket sales.

Sale of Mileage Credits. Customers may earn mileage credits through participating companies such as credit card companies, hotels and car rental agencies with which we have marketing agreements to sell mileage credits. Our contracts to sell mileage credits under these marketing agreements have multiple deliverables, as defined below.

Our most significant contract to sell mileage credits relates to our co-brand credit card relationship with American Express. In December 2014, we amended our marketing agreements with American Express, which increased the value we receive under the agreements through 2022. The amended agreements became effective January 1, 2015. We account for the agreements consistent with the accounting method that allocates the consideration received to the individual products and services delivered based on their relative selling prices. We determined our best estimate of the selling prices by considering discounted cash flow analysis using multiple inputs and assumptions, including: (1) the expected number of miles awarded and number of miles redeemed, (2) the rate at which we sell mileage credits to other airlines, (3) published rates on our website for baggage fees, discounted access to Delta Sky Club lounges and other benefits while traveling on Delta and (4) brand value. The increased value received under the amended agreements increases the amount of deferred revenue for the travel component and increases the value of the other deliverables, which are recognized in other revenue as they are provided.

We recognize revenue as we deliver each sales element. We defer the travel deliverable (mileage credits) as part of frequent flyer deferred revenue and recognize passenger revenue as the mileage credits are used for travel. The revenue allocated to the remaining deliverables is recorded in other revenue. We recognize the revenue for these services as they are performed.



## Table of Contents

Breakage. For mileage credits that we estimate are not likely to be redeemed ("breakage"), we recognize the associated value proportionally during the period in which the remaining mileage credits are expected to be redeemed. We use statistical models to estimate breakage based on historical redemption patterns. A change in assumptions as to the period over which mileage credits are expected to be redeemed, the actual redemption activity for mileage credits or the estimated fair value of mileage credits expected to be redeemed could have a material impact on our revenue in the year in which the change occurs and in future years. At December 31, 2017, the aggregate deferred revenue balance associated with the SkyMiles program was $4.1 billion. A hypothetical 1% change in the number of outstanding miles estimated to be redeemed would result in a $34 million impact on our deferred revenue liability at December 31, 2017.

## Goodwill and Indefinite-Lived Intangible Assets

We apply a fair value-based impairment test to the carrying value of goodwill and indefinite-lived intangible assets on an annual basis (as of October 1) and, if certain events or circumstances indicate that an impairment loss may have been incurred, on an interim basis. We assess the value of our goodwill and indefinite-lived assets under either a qualitative or quantitative approach. Under a qualitative approach, we consider various market factors, including the key assumptions listed below. We analyze these factors to determine if events and circumstances have affected the fair value of goodwill and indefinite-lived intangible assets. If we determine that it is more likely than not that the asset may be impaired, we use the quantitative approach to assess the asset's fair value and the amount of the impairment. Under a quantitative approach, we calculate the fair value of the asset using the key assumptions listed below.

When we evaluate goodwill for impairment using a quantitative approach, we estimate the fair value of the reporting unit by considering both market capitalization and projected discounted future cash flows (an income approach). When we perform a quantitative impairment assessment of our indefinite-lived intangible assets, fair value is estimated based on (1) recent market transactions, where available, (2) the royalty method for the Delta tradename (which assumes hypothetical royalties generated from using our tradename) or (3) projected discounted future cash flows (an income approach).

Key Assumptions. The key assumptions in our impairment tests include: (1) forecasted revenues, expenses and cash flows, (2) terminal period revenue growth and cash flows, (3) an estimated weighted average cost of capital, (4) assumed discount rates depending on the asset and (5) a tax rate. These assumptions are consistent with those hypothetical market participants would use. Since we are required to make estimates and assumptions when evaluating goodwill and indefinite-lived intangible assets for impairment, actual transaction amounts may differ materially from these estimates. In addition, we consider the amount by which the intangible assets' fair values exceeded their respective carrying values in the most recent fair value measurements calculated using a quantitative approach.

Changes in certain events and circumstances could result in impairment or a change from indefinite-lived to definite-lived. Factors which could cause impairment include, but are not limited to, (1) negative trends in our market capitalization, (2) reduced profitability resulting from lower passenger mile yields or higher input costs (primarily related to fuel and employees), (3) lower passenger demand as a result of weakened U.S. and global economies, (4) interruption to our operations due to a prolonged employee strike, terrorist attack or other reasons, (5) changes to the regulatory environment (e.g., diminished slot restrictions or additional Open Skies agreements), (6) competitive changes by other airlines and (7) strategic changes to our operations leading to diminished utilization of the intangible assets.

We assessed each of the above assumptions in our most recent impairment analyses. The combination of our most recently completed annual results and our projected revenues, expenses and cash flows more than offset any negative events and circumstances. The stabilized operating environment for U.S. airlines has also contributed to improved financial results.

Goodwill. Our goodwill balance, which is related to the airline segment, was $9.8 billion at December 31, 2017. Based upon our qualitative assessment of all relevant factors, including applicable factors noted in "Key Assumptions" above, we determined that there was no indication that goodwill was impaired.

Identifiable Intangible Assets. Our identifiable intangible assets, which are related to the airline segment, had a net carrying amount of $4.8 billion at December 31, 2017, of which $4.7 billion related to indefinite-lived intangible assets. Indefinite-lived assets are not amortized and consist primarily of routes, slots, the Delta tradename and assets related to SkyTeam and collaborative arrangements. Definite-lived assets consist primarily of marketing and maintenance service agreements.

We performed qualitative assessments of our indefinite-lived intangible assets, including applicable factors noted in "Key Assumptions" above, and determined that there was no indication that the assets were impaired. Our qualitative assessments include analyses and weighting of all relevant factors, which impact the fair value of our indefinite-lived intangible assets.

## Long-Lived Assets

Our flight equipment and other long-lived assets have a recorded value of $26.6 billion at December 31, 2017. This value is based on various factors, including the assets' estimated useful lives and salvage values. We review flight equipment and other long-lived assets used in operations for impairment losses when events and circumstances indicate the assets may be impaired. Factors which could be indicators of impairment include, but are not limited to, (1) a decision to permanently remove flight equipment or other long-lived assets from operations, (2) significant changes in the estimated useful life, (3) significant changes in projected cash flows, (4) permanent and significant declines in fleet fair values and (5) changes to the regulatory environment. For long-lived assets held for sale, we discontinue depreciation and record impairment losses when the carrying amount of these assets is greater than the fair value less the cost to sell.

To determine whether impairments exist for aircraft used in operations, we group assets at the fleet-type level (the lowest level for which there are identifiable cash flows) and then estimate future cash flows based on projections of capacity, passenger mile yield, fuel costs, labor costs and other relevant factors. If an impairment occurs, the impairment loss recognized is the amount by which the fleet's carrying amount exceeds its estimated fair value. We estimate aircraft fair values using published sources, appraisals and bids received from third parties, as available.

## Defined Benefit Pension Plans

We sponsor defined benefit pension plans for eligible employees and retirees. These plans are closed to new entrants and frozen for future benefit accruals. As of December 31, 2017, the unfunded benefit obligation for these plans recorded on our Consolidated Balance Sheet was $7.0 billion. During 2017, we contributed $3.5 billion to these plans. We have no minimum funding requirements in 2018. However, in January 2018, we voluntarily contributed approximately $500 million to these plans. The most critical assumptions impacting our defined benefit pension plan obligations and expenses are the discount rate, the expected long-term rate of return on plan assets and life expectancy.

Weighted Average Discount Rate. We determine our weighted average discount rate on our measurement date primarily by reference to annualized rates earned on high-quality fixed income investments and yield-to-maturity analysis specific to our estimated future benefit payments. We used a weighted average discount rate to value the obligations of 3.69% and 4.20% at December 31, 2017 and 2016, respectively. Our weighted average discount rate for net periodic pension benefit cost in each of the past three years has varied from the rate selected on our measurement date, ranging from 4.13% to 4.57% between 2015 and 2017.

Expected Long-Term Rate of Return. Our expected long-term rate of return on plan assets is based primarily on plan-specific investment studies using historical market return and volatility data. Modest excess return expectations versus some public market indices are incorporated into the return projections based on the actively managed structure of the investment programs and their records of achieving such returns historically. We also expect to receive a premium for investing in less liquid private markets. We review our rate of return on plan assets assumptions annually. Our annual investment performance for one particular year does not, by itself, significantly influence our evaluation. The investment strategy for our defined benefit pension plan assets is to earn a long-term return that meets or exceeds our annualized return target while taking an acceptable level of risk and maintaining sufficient liquidity to pay current benefits and other cash obligations of the plan. This is achieved by investing in a globally diversified mix of public and private equity, fixed income, real assets, hedge funds and other assets and instruments. Our expected long-term rate of return on assets for net periodic pension benefit cost for the year ended December 31, 2017 was 8.96%.

The impact of a 0.50% change in these assumptions is shown in the table below:

<table><tr><td>Change in Assumption</td><td>Effect on 2018 Pension Expense</td><td>Effect on Accrued Pension Liability at December 31, 2017</td></tr><tr><td>0.50% decrease in weighted average discount rate</td><td>$ (9) million</td><td>$ 1.4 billion</td></tr><tr><td>0.50% increase in weighted average discount rate</td><td>$ 5 million</td><td>$ (1.2) billion</td></tr><tr><td>0.50% decrease in expected long-term rate of return on assets</td><td>$ 73 million</td><td>$ —</td></tr><tr><td>0.50% increase in expected long-term rate of return on assets</td><td>$ (73) million</td><td>$ —</td></tr></table>



## Table of Contents

Life Expectancy. Changes in life expectancy may significantly change our benefit obligations and future expense. We use the Society of Actuaries ("SOA") published mortality data, other publicly available information and our own perspective of future longevity to develop our best estimate of life expectancy. The SOA publishes annual updated mortality tables for U.S. plans and updated improvement scale. Each year we consider updates by the SOA in setting our mortality assumptions for purposes of measuring pension and other postretirement and postemployment benefit obligations.

Funding. Our funding obligations for qualified defined benefit plans are governed by the Employee Retirement Income Security Act. The Pension Protection Act of 2006 allows commercial airlines to elect alternative funding rules ("Alternative Funding Rules") for defined benefit plans that are frozen. We elected the Alternative Funding Rules under which the unfunded liability for a frozen defined benefit plan may be amortized over a fixed 17-year period and is calculated using an 8.85% discount rate.

While the Pension Protection Act makes our funding obligations for these plans more predictable, factors outside our control continue to have an impact on the funding requirements. Estimates of future funding requirements are based on various assumptions and can vary materially from actual funding requirements. Assumptions include, among other things, the actual and projected market performance of assets, statutory requirements and demographic data for participants. For additional information, see Note 9 of the Notes to the Consolidated Financial Statements.

## Recent Accounting Standards

## Revenue from Contracts with Customers

On January 1, 2018, we will adopt ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" using the full retrospective method. While the adoption will not have a significant impact on earnings, the classification of certain revenues that are currently classified in other revenue will be reclassified to passenger revenue. These include baggage fees, administrative charges and other travel-related fees, all of which will be deemed part of the single performance obligation of providing passenger transportation. These revenues, which are approximately $2 billion annually, will be reclassified from the current presentation in other revenue to passenger revenue.

In addition, the adoption of the new standard increases the rate used to account for frequent flyer miles. We currently analyze our standalone sales of mileage credits to other airlines and customers to establish the accounting value for frequent flyer miles. Considering the guidance in the new standard, we will change our valuation of a mileage credit to an analysis of the award redemption value. The new valuation considers the value a passenger receives by redeeming miles rather than paying cash for an award ticket. This change increases our frequent flyer liability by approximately $2 billion. The mileage deferral and redemption rates are approximately the same; therefore, assuming stable volume, there would not be a significant change in revenue recognized from the program for a given period.

The adoption of the new standard will also reduce our air traffic liability by approximately $500 million. This change primarily results from estimating the tickets that will expire unused and recognizing revenue at the scheduled flight date rather than when the unused tickets expire.

## Retirement Benefits

In 2017, the FASB issued ASU No. 2017-07, "Compensation—Retirement Benefits (Topic 715)." This standard requires an entity to report the service cost component in the same line item as other compensation costs. The other components of net (benefit) cost will be required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. In 2017, we recorded $50 million of non-service costs that will be reclassified to non-operating expense upon adoption. This standard is effective for interim and annual reporting periods beginning after December 15, 2017. We will adopt the standard effective January 1, 2018.



See the table below for the unaudited impact resulting from the adoption of these standards on our Consolidated Financial Statements.

## Supplemental Information

We sometimes use information ("non-GAAP financial measures") that is derived from the Consolidated Financial Statements but that is not presented in accordance with GAAP. Under the U.S. Securities and Exchange Commission rules, non-GAAP financial measures may be considered in addition to results prepared in accordance with GAAP but should not be considered a substitute for our superior to GAAP results.

The following table shows a reconciliation of pre-tax income (a GAAP measure) to pre-tax income, adjusted for special items (a non-GAAP financial measure). We adjust pre-tax income for the following items to determine pre-tax income, adjusted for special items, for the reasons described below:

- MTM adjustments and settlements. MTM adjustments are defined as fair value changes recorded in periods other than the settlement period. Such fair value changes are not necessarily indicative of the actual settlement value of the underlying hedge in the contract settlement period. Settlements represent cash received or paid on hedge contracts settled during the period. These items adjust fuel expense to show the economic impact of hedging, including cash received or paid on hedge contracts during the period. Adjusting for these items allows investors to better understand and analyze our core operational performance in the periods shown.

- Investment MTM adjustments. We record our proportionate share of earnings from our equity investments in Virgin Atlantic and Aeroméxico in non-operating expense. We adjust for Virgin Atlantic's and Aeroméxico's MTM adjustments to allow investors to better understand and analyze our core financial performance in the periods shown.

The following table shows a reconciliation of CASM (a GAAP measure) to CASM-Ex, including profit sharing (a non-GAAP financial measure). We adjust CASM for the following items to determine CASM-Ex, including profit sharing for the reasons described below:

- Aircraft fuel and related taxes. The volatility in fuel prices impacts the comparability of year-over-year financial performance. The adjustment for aircraft fuel and related taxes (including our regional carriers) allows investors to better understand and analyze our non-fuel costs and year-over-year financial performance.

- Other expenses. Other expenses include aircraft maintenance and staffing services we provide to third parties, our vacation wholesale operations and refinery cost of sales to third parties. Because these businesses are not related to the generation of a seat mile, we adjust for the costs related to these sales to provide a more meaningful comparison of the costs of our airline operations to the rest of the airline industry.

## ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We have market risk exposure related to fuel prices, interest rates and foreign currency exchange rates. Market risk is the potential negative impact of adverse changes in these prices or rates on our Consolidated Financial Statements. In an effort to manage our exposure to these risks, we enter into derivative contracts and may adjust our derivative portfolio as market conditions change. We expect adjustments to the fair value of financial instruments to result in ongoing volatility in earnings and stockholders' equity.

The following sensitivity analyses do not consider the effects of a change in demand for air travel, the economy as a whole or actions we may take to seek to mitigate our exposure to a particular risk. For these and other reasons, the actual results of changes in these prices or rates may differ materially from the following hypothetical results.

## Fuel Price Risk

Changes in fuel prices materially impact our results of operations. We have recently managed our fuel price risk through a hedging program intended to reduce the financial impact from changes in the price of fuel as fuel prices are subject to potential volatility. A one cent increase in the cost of jet fuel would result in approximately $40 million of additional annual fuel expense.

## Interest Rate Risk

Our exposure to market risk from adverse changes in interest rates is primarily associated with our long-term debt obligations. Market risk associated with our fixed and variable rate long-term debt relates to the potential reduction in fair value and negative impact to future earnings, respectively, from an increase in interest rates.

At December 31, 2017, we had $5.3 billion of fixed-rate long-term debt and $3.2 billion of variable-rate long-term debt. An increase of 100 basis points in average annual interest rates would have decreased the estimated fair value of our fixed-rate long-term debt by $160 million at December 31, 2017 and would have increased the annual interest expense on our variable-rate long-term debt by $32 million.

## Foreign Currency Exchange Risk

We are subject to foreign currency exchange rate risk because we have revenue and expense denominated in foreign currencies with our primary exposures being the Japanese yen and Canadian dollar. To manage exchange rate risk, we execute both our international revenue and expense transactions in the same foreign currency to the extent practicable. From time to time, we may also enter into foreign currency option and forward contracts. At December 31, 2017, we had open foreign currency forward contracts totaling a $17 million liability position. We estimate that a 10% depreciation or appreciation in the price of the Japanese yen and Canadian dollar in relation to the U.S. dollar would change the projected cash settlement value of our open hedge contracts by a $34 million gain or $42 million loss, respectively, for the year ending December 31, 2018.

## REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Delta Air Lines, Inc.

## Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Delta Air Lines, Inc. (the Company) as of December 31, 2017 and 2016, and the related consolidated statements of operations, comprehensive income, cash flows, and stockholders' equity for each of the three years in the period ended December 31, 2017, 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, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, 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, 2017, 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 23, 2018 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 misstatements 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.

We have served as the Company's auditor since 2006.

## NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

## NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

## Basis of Presentation

Delta Air Lines, Inc., a Delaware corporation, provides scheduled air transportation for passengers and cargo throughout the United States ("U.S.") and around the world. Our Consolidated Financial Statements include the accounts of Delta Air Lines, Inc. and our wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP"). We do not consolidate the financial statements of any company in which we have an ownership interest of 50% or less. We are not the primary beneficiary of, nor do we have a controlling financial interest in, any variable interest entity. Accordingly, we have not consolidated any variable interest entity.

We have marketing alliances with other airlines to enhance our access to domestic and international markets. These arrangements may include codesharing, reciprocal frequent flyer program benefits, shared or reciprocal access to passenger lounges, joint promotions, common use of airport gates and ticket counters, ticket office co-location and other marketing agreements. We have received antitrust immunity for certain marketing arrangements, which enables us to offer a more integrated route network and develop common sales, marketing and discount programs for customers. Some of our marketing arrangements provide for the sharing of revenues and expenses. Revenues and expenses associated with collaborative arrangements are presented on a gross basis in the applicable line items on our Consolidated Statements of Operations.

We reclassified certain prior period amounts to conform to the current period presentation. Unless otherwise noted, all amounts disclosed are stated before consideration of income taxes.

## Use of Estimates

We are required to make estimates and assumptions when preparing our Consolidated Financial Statements in accordance with GAAP. These estimates and assumptions affect the amounts reported in our Consolidated Financial Statements and the accompanying notes. Actual results could differ materially from those estimates.

## Recent Accounting Standards

Revenue from Contracts with Customers. In 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." Under this ASU and subsequently issued amendments, revenue is recognized at the time a good or service is transferred to a customer for the amount of consideration received. Entities may use a full retrospective approach or report the cumulative effect as of the date of adoption. We will adopt the standard effective January 1, 2018 using the full retrospective approach.

While the adoption of the new standard will not have a significant effect on earnings, the classification of certain revenues that are currently classified in other revenue will be reclassified to passenger revenue. These include baggage fees, administrative charges and other travel-related fees, all of which will be deemed part of the single performance obligation of providing passenger transportation. These revenues, which are approximately $2 billion annually, will be reclassified from the current presentation in other revenue to passenger revenue after adoption.

In addition, the adoption of the new standard increases the rate used to account for frequent flyer miles. We currently analyze our standalone sales of mileage credits to other airlines and customers to establish the accounting value for frequent flyer miles. Considering the guidance in the new standard, we will change our valuation of a mileage credit to an analysis of the award redemption value. The new valuation considers the value a passenger receives by redeeming miles rather than paying cash for an award ticket. This change increases our frequent flyer liability by approximately $2 billion. The mileage deferral and redemption rates are approximately the same; therefore, assuming stable volume, there would not be a significant change in revenue recognized from the program for a given period.

The adoption of the new standard will also reduce our air traffic liability by approximately $500 million. This change primarily results from estimating the tickets that will expire unused and recognizing revenue at the scheduled flight date rather than when the unused tickets expire.

Leases. In 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." This standard will require all leases with durations greater than twelve months to be recognized on the balance sheet and is effective for interim and annual reporting periods beginning after December 15, 2018.



## Table of Contents

We have not completed our assessment, but the adoption of this standard will have a significant impact on our Consolidated Balance Sheets. However, we do not expect the adoption to have a significant impact on the recognition, measurement or presentation of lease expenses within the Consolidated Statements of Operations or the Consolidated Statements of Cash Flows. Information about our undiscounted future lease payments and the timing of those payments is in Note 7, "Lease Obligations." We will adopt this standard effective January 1, 2019.

Statement of Cash Flows. In 2016, the FASB issued ASU Nos. 2016-15 and 2016-18 related to the classification of certain cash receipts and cash payments and the presentation of restricted cash within an entity's statement of cash flows, respectively. We will adopt the standards effective January 1, 2018.

Financial Instruments. In 2016, the FASB issued ASU No. 2016-01, "Financial Instruments—Overall (Subtopic 825-10)." This standard makes several changes, including the elimination of the available-for-sale classification of equity investments, and requires equity investments with readily determinable fair values to be measured at fair value with changes in fair value recognized in net income. We will adopt the standard effective January 1, 2018. This standard does not apply to our investments in Grupo Aeroméxico and Virgin Atlantic, which are accounted for under the equity method.

Our investments in GOL Linhas Aéreas Inteligentes, the parent company of VRG Linhas Aéreas (operating as GOL) and China Eastern are currently accounted for as available-for-sale with changes in fair value recognized in other comprehensive income. At the time of adoption, the balance in accumulated other comprehensive income/(loss) ("AOCI") related to equity investments will be reclassified to retained earnings. As of December 31, 2017, a net unrealized gain of $162 million related to these investments was recorded in AOCI on our Consolidated Balance Sheet.

Our investment in Air France-KLM is currently accounted for at cost as our investment agreement restricts the sale or transfer of these shares for five years. Despite the restriction, upon adoption of ASU No. 2016-01, this investment will be accounted for at fair value with changes in fair value recognized in net income.

Retirement Benefits. In 2017, the FASB issued ASU No. 2017-07, "Compensation—Retirement Benefits (Topic 715)." This standard requires an entity to report the service cost component in the same line item as other compensation costs. The other components of net (benefit) cost will be required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. In 2017, we recorded $50 million of non-service costs that will be reclassified to non-operating expense upon adoption. This standard is effective for interim and annual reporting periods beginning after December 15, 2017. We will adopt the standard effective January 1, 2018.

Comprehensive Income. In February 2018, the FASB issued ASU No. 2018-02, "Income Statement—Reporting Comprehensive Income (Topic 220)." This standard provides financial statement preparers with an option to reclassify stranded tax effects within AOCI from retained earnings due to the U.S. federal corporate income tax rate change in the Tax Cuts and Jobs Act of 2017. This standard is effective for interim and annual reporting periods beginning after December 15, 2018, and early adoption is permitted. The adoption of the standard may impact tax amounts stranded in AOCI related to our pension plans. See Note 11 of the Notes to the Consolidated Financial Statements for more information.

## Cash and Cash Equivalents and Short-Term Investments

Short-term, highly liquid investments with maturities of three months or less when purchased are classified as cash and cash equivalents. Investments with maturities of greater than three months, but not in excess of one year, when purchased are classified as short-term investments. Investments with maturities beyond one year when purchased may be classified as short-term investments if they are expected to be available to support our short-term liquidity needs. All short-term investments are classified as either available-for-sale or held-to-maturity, and realized gains and losses are recorded using the specific identification method.

## Accounts Receivable

Accounts receivable primarily consist of amounts due from credit card companies from the sale of passenger airline tickets, customers of our aircraft maintenance and cargo transportation services and other companies for the purchase of mileage credits under our frequent flyer program (the "SkyMiles program"). We provide an allowance for uncollectible accounts equal to the estimated losses expected to be incurred based on historical chargebacks, write-offs, bankruptcies and other specific analyses. Bad debt expense was not material in any period presented.



## Inventories

Spare Parts. Inventories of expendable parts related to flight equipment, which cannot be economically repaired, reconditioned or reused after removal from the aircraft, are carried at moving average cost and charged to operations as consumed. An allowance for obsolescence is provided over the remaining useful life of the related fleet. We also provide allowances for parts identified as excess or obsolete to reduce the carrying costs to the lower of cost or net realizable value. These parts are assumed to have an estimated residual value of 5% of the original cost.

Refinery. Refined product, feedstock and blendstock inventories, all of which are finished goods, are carried at recoverable cost. We use jet fuel in our airline operations that is produced by the refinery and procured through the exchange with third parties of gasoline, diesel and other refined products ("non-jet fuel products") the refinery produces. Cost is determined using the first-in, first-out method. Costs include the raw material consumed plus direct manufacturing costs (such as labor, utilities and supplies) incurred and an applicable portion of manufacturing overhead.

## Accounting for Refinery Related Buy/Sell Agreements

To the extent that we receive jet fuel for non-jet fuel products exchanged under buy/sell agreements, we account for these transactions as nonmonetary exchanges. We have recorded these nonmonetary exchanges at the carrying amount of the non-jet fuel products transferred within aircraft fuel and related taxes on the Consolidated Statements of Operations.

## Derivatives

Changes in fuel prices, interest rates and foreign currency exchange rates impact our results of operations. In an effort to manage our exposure to these risks, we may enter into derivative contracts and adjust our derivative portfolio as market conditions change. We recognize derivative contracts at fair value on our Consolidated Balance Sheets.

Not Designated as Accounting Hedges. We do not designate our fuel derivative contracts as accounting hedges. We recorded changes in the fair value of our fuel hedges in aircraft fuel and related taxes. These changes in fair value include settled gains and losses as well as mark-to-market adjustments ("MTM adjustments"). MTM adjustments are defined as fair value changes recorded in periods other than the settlement period. Such fair value changes are not necessarily indicative of the actual settlement value of the underlying hedge in the contract settlement period.

Designated as Cash Flow Hedges. For derivative contracts designated as cash flow hedges (interest rate contracts and foreign currency exchange contracts), the effective portion of the gain or loss on the derivative is reported as a component of AOCI and reclassified into earnings in the same period in which the hedged transaction affects earnings. The effective portion of the derivative represents the change in fair value of the hedge that offsets the change in fair value of the hedged item. To the extent the change in the fair value of the hedge does not perfectly offset the change in the fair value of the hedged item, the ineffective portion of the hedge is immediately recognized in non-operating expense.

Designated as Fair Value Hedges. For derivative contracts designated as fair value hedges (interest rate contracts), the gain or loss on the derivative is reported in earnings and an equivalent amount is reflected as a change in the carrying value of long-term debt and capital leases, with an offsetting loss or gain recognized in current earnings. We include the gain or loss on the hedged item in the same account as the offsetting loss or gain on the related derivative contract, resulting in no impact to our Consolidated Statements of Operations.

The following table summarizes the risk each type of derivative contract is hedging and the classification of related gains and losses on our Consolidated Statements of Operations:

<table><tr><td>Derivative Type</td><td>Hedged Risk</td><td>Classification of Gains and Losses</td></tr><tr><td>Fuel hedge contracts</td><td>Fluctuations in fuel prices</td><td>Aircraft fuel and related taxes</td></tr><tr><td>Interest rate contracts</td><td>Increases in interest rates</td><td>Interest expense, net</td></tr><tr><td>Foreign currency exchange contracts</td><td>Fluctuations in foreign currency exchange rates</td><td>Passenger revenue</td></tr></table>



## Table of Contents

The following table summarizes the accounting treatment of our derivative contracts:

<table><tr><td rowspan="2">Accounting Designation</td><td colspan="2">Impact of Unrealized Gains and Losses</td></tr><tr><td>Effective Portion</td><td>Ineffective Portion</td></tr><tr><td>Not designated as hedges</td><td colspan="2">Change in fair value of hedge is recorded in earnings</td></tr><tr><td>Designated as cash flow hedges</td><td>Market adjustments are recorded in AOCI</td><td>Excess, if any, over effective portion of hedge is recorded in non-operating expense</td></tr><tr><td>Designated as fair value hedges</td><td>Market adjustments are recorded in long-term debt and capital leases</td><td>Excess, if any, over effective portion of hedge is recorded in non-operating expense</td></tr></table>

We perform, at least quarterly, an assessment of the effectiveness of our derivative contracts designated as hedges, including assessing the possibility of counterparty default. If we determine that a derivative is no longer expected to be highly effective, we discontinue hedge accounting prospectively and recognize subsequent changes in the fair value of the hedge in earnings. We believe our derivative contracts that continue to be designated as hedges, consisting of interest rate and foreign currency exchange contracts, will continue to be highly effective in offsetting changes in fair value or cash flow, respectively, attributable to the hedged risk.

Cash flows associated with purchasing and settling hedge contracts generally are classified as operating cash flows. However, if a hedge contract includes a significant financing element at inception, cash flows associated with the hedge contract are recorded as financing cash flows.

Hedge Margin. In accordance with our fuel, interest rate and foreign currency hedge contracts, we may require counterparties to fund the margin associated with our gain position and/or counterparties may require us to fund the margin associated with our loss position on these contracts. The amount of the margin, if any, is periodically adjusted based on the fair value of the hedge contracts. The margin requirements are intended to mitigate a party's exposure to the risk of counterparty default. We do not offset margin funded to counterparties or margin funded to us by counterparties against fair value amounts recorded for our hedge contracts.

The hedge margin we receive from counterparties is recorded in prepaid expenses and other, with the offsetting obligation in accounts payable. The hedge margin we provide to counterparties is recorded in prepaid expenses and other.

## Long-Lived Assets

The following table summarizes our property and equipment:

<table><tr><td rowspan="2">(in millions, except for estimated useful life)</td><td rowspan="2">Estimated Useful Life</td><td colspan="2">December 31,</td></tr><tr><td>2017</td><td>2016</td></tr><tr><td>Flight equipment</td><td>20-32 years</td><td>$ 30,688</td><td>$ 28,135</td></tr><tr><td>Ground property and equipment</td><td>3-40 years</td><td>7,665</td><td>6,581</td></tr><tr><td>Flight and ground equipment under capital leases</td><td>Shorter of lease term or estimated useful life</td><td>1,147</td><td>1,056</td></tr><tr><td>Advance payments for equipment</td><td></td><td>1,160</td><td>1,059</td></tr><tr><td>Less: accumulated depreciation and amortization (1)</td><td></td><td>(14,097)</td><td>(12,456)</td></tr><tr><td>Total property and equipment, net</td><td></td><td>$ 26,563</td><td>$ 24,375</td></tr></table>

(1) Includes accumulated amortization for flight and ground equipment under capital leases in the amount of $668 million and $757 million at December 31, 2017 and 2016, respectively.

We record property and equipment at cost and depreciate or amortize these assets on a straight-line basis to their estimated residual values over their estimated useful lives. The estimated useful life for leasehold improvements is the shorter of lease term or estimated useful life. Depreciation and amortization expense related to our property and equipment was $2.2 billion, $1.9 billion and $1.8 billion for each of the years ended December 31, 2017, 2016 and 2015, respectively. Residual values for owned aircraft, engines, spare parts and simulators are generally 5% to 10% of cost.

We capitalize certain internal and external costs incurred to develop and implement software and amortize those costs over an estimated useful life of three to 10 years. Included in the depreciation and amortization expense discussed above, we recorded $189 million, $160 million and $148 million for amortization of capitalized software for the years ended December 31, 2017, 2016 and 2015, respectively. The net book value of these assets totaled $659 million and $549 million at December 31, 2017 and 2016, respectively.



## Table of Contents

We review flight equipment and other long-lived assets used in operations for impairment losses when events and circumstances indicate the assets may be impaired. Factors which could be indicators of impairment include, but are not limited to, (1) a decision to permanently remove flight equipment or other long-lived assets from operations, (2) significant changes in the estimated useful life, (3) significant changes in projected cash flows, (4) permanent and significant declines in fleet fair values and (5) changes to the regulatory environment. For long-lived assets held for sale, we discontinue depreciation and record impairment losses when the carrying amount of these assets is greater than the fair value less the cost to sell.

To determine whether impairments exist for aircraft used in operations, we group assets at the fleet-type level (the lowest level for which there are identifiable cash flows) and then estimate future cash flows based on projections of capacity, passenger mile yield, fuel costs, labor costs and other relevant factors. If an impairment occurs, the impairment loss recognized is the amount by which the fleet's carrying amount exceeds its estimated fair value. We estimate aircraft fair values using published sources, appraisals and bids received from third parties, as available.

## Goodwill and Other Intangible Assets

Our goodwill and identifiable intangible assets relate to the airline segment. We apply a fair value-based impairment test to the carrying value of goodwill and indefinite-lived intangible assets on an annual basis (as of October 1) and, if certain events or circumstances indicate that an impairment loss may have been incurred, on an interim basis. We assess the value of our goodwill and indefinite-lived assets under either a qualitative or quantitative approach. Under a qualitative approach, we consider various market factors, including the key assumptions listed below. We analyze these factors to determine if events and circumstances have affected the fair value of goodwill and indefinite-lived intangible assets. If we determine that it is more likely than not that the asset may be impaired, we use the quantitative approach to assess the asset's fair value and the amount of the impairment. Under a quantitative approach, we calculate the fair value of the asset using the key assumptions listed below.

We value goodwill and indefinite-lived intangible assets primarily using market capitalization and income approach valuation techniques. These measurements include the following key assumptions: (1) forecasted revenues, expenses and cash flows, (2) terminal period revenue growth and cash flows, (3) an estimated weighted average cost of capital, (4) assumed discount rates depending on the asset and (5) a tax rate. These assumptions are consistent with those hypothetical market participants would use. Since we are required to make estimates and assumptions when evaluating goodwill and indefinite-lived intangible assets for impairment, actual transaction amounts may differ materially from these estimates.

Changes in certain events and circumstances could result in impairment or a change from indefinite-lived to definite-lived. Factors which could cause impairment include, but are not limited to, (1) negative trends in our market capitalization, (2) reduced profitability resulting from lower passenger mile yields or higher input costs (primarily related to fuel and employees), (3) lower passenger demand as a result of weakened U.S. and global economies, (4) interruption to our operations due to a prolonged employee strike, terrorist attack or other reasons, (5) changes to the regulatory environment (e.g., diminished slot restrictions or additional Open Skies agreements), (6) competitive changes by other airlines and (7) strategic changes to our operations leading to diminished utilization of the intangible assets.

Goodwill. When we evaluate goodwill for impairment using a quantitative approach, we estimate the fair value of the reporting unit by considering both market capitalization and projected discounted future cash flows (an income approach). If the reporting unit's fair value exceeds its carrying value, no further testing is required. If, however, the reporting unit's carrying value exceeds its fair value, we then determine the amount of the impairment charge, if any. We recognize an impairment charge if the carrying value of the reporting unit's goodwill exceeds its estimated fair value.



## Table of Contents

Identifiable Intangible Assets. Indefinite-lived assets are not amortized and consist of routes, slots, the Delta tradename and assets related to SkyTeam and collaborative arrangements. Definite-lived intangible assets consist primarily of marketing and maintenance service agreements and are amortized on a straight-line basis or under the undiscounted cash flows method over the estimated economic life of the respective agreements. Costs incurred to renew or extend the term of an intangible asset are expensed as incurred.

We assess our indefinite-lived assets under a qualitative or quantitative approach. We analyze market factors to determine if events and circumstances have affected the fair value of the indefinite-lived intangible assets. If we determine that it is more likely than not that the asset value may be impaired, we use the quantitative approach to assess the asset's fair value and the amount of the impairment. We perform the quantitative impairment test for indefinite-lived intangible assets by comparing the asset's fair value to its carrying value. Fair value is estimated based on (1) recent market transactions, where available, (2) the royalty method for the Delta tradename (which assumes hypothetical royalties generated from using our tradename) or (3) projected discounted future cash flows (an income approach). We recognize an impairment charge if the asset's carrying value exceeds its estimated fair value.

## Income Taxes

We account for deferred income taxes under the liability method. We recognize deferred tax assets and liabilities based on the tax effects of temporary differences between the financial statement and tax basis of assets and liabilities, as measured by current enacted tax rates. Deferred tax assets and liabilities are recorded net as noncurrent deferred income taxes.

A valuation allowance is recorded to reduce deferred tax assets when necessary. We periodically assess whether it is more likely than not that we will generate sufficient taxable income to realize our deferred income tax assets. We establish valuation allowances if it is not likely we will realize our deferred income tax assets. In making this determination, we consider all available positive and negative evidence and make certain assumptions. We consider, among other things, projected future taxable income, scheduled reversals of deferred tax liabilities, the overall business environment, our historical financial results and tax planning strategies.

## Fuel Card Obligation

We have a purchasing card with American Express for the purpose of buying jet fuel and crude oil. The card currently carries a maximum credit limit of $1.1 billion and must be paid monthly. At December 31, 2017 and December 31, 2016, we had $1.1 billion and $431 million, respectively, outstanding on this purchasing card, which was classified as a financing activity in our Consolidated Statements of Cash Flows.

## Retirement of Repurchased Shares

We immediately retire shares repurchased pursuant to our share repurchase program. We allocate the share purchase price in excess of par value between APIC and retained earnings.

## Passenger Tickets

We record sales of passenger tickets in air traffic liability. Passenger revenue is recognized when we provide transportation or when the ticket expires unused, reducing the related air traffic liability. We periodically evaluate the estimated air traffic liability and record any adjustments in our Consolidated Statements of Operations. These adjustments relate primarily to refunds, exchanges, transactions with other airlines and other items for which final settlement occurs in periods subsequent to the sale of the related tickets at amounts other than the original sales price.

## Passenger Taxes and Fees

We are required to charge certain taxes and fees on our passenger tickets, including U.S. federal transportation taxes, federal security charges, airport passenger facility charges and foreign arrival and departure taxes. These taxes and fees are assessments on the customer for which we act as a collection agent. Because we are not entitled to retain these taxes and fees, we do not include such amounts in passenger revenue. We record a liability when the amounts are collected and reduce the liability when payments are made to the applicable government agency or operating carrier.



## Frequent Flyer Program

Our SkyMiles program offers incentives to travel on Delta. This program allows customers to earn mileage credits by flying on Delta, Delta Connection and airlines that participate in the SkyMiles program, as well as through participating companies such as credit card companies, hotels and car rental agencies. We sell mileage credits to non-airline businesses, customers and other airlines. Effective January 1, 2015, the SkyMiles program was modified from a model in which customers earn redeemable mileage credits based on distance traveled to a model based on ticket price. This award change did not affect the way we account for the program.

The SkyMiles program includes two types of transactions that are considered revenue arrangements with multiple deliverables. As discussed below, these are (1) passenger ticket sales earning mileage credits and (2) the sale of mileage credits to participating companies with which we have marketing agreements. Mileage credits are a separate unit of accounting as they can be redeemed by customers in future periods for air travel on Delta and participating airlines, membership in our Sky Club and other program awards.

Passenger Ticket Sales Earning Mileage Credits. Passenger ticket sales earning mileage credits under our SkyMiles program provide customers with (1) mileage credits earned and (2) air transportation. We value each deliverable on a standalone basis. Our estimate of the selling price of a mileage credit is based on an analysis of our sales of mileage credits to other airlines and customers, which is re-evaluated at least annually. We use established ticket prices to determine the estimated selling price of air transportation. We allocate the total amount collected from passenger ticket sales between the deliverables based on their relative selling prices.

We defer revenue for the mileage credits related to passenger ticket sales when the credits are earned and recognize it as passenger revenue when miles are redeemed and services are provided. We record the air transportation portion of the passenger ticket sales in air traffic liability and recognize these amounts in passenger revenue when we provide transportation or when the ticket expires unused.

Sale of Mileage Credits. Customers may earn mileage credits through participating companies such as credit card companies, hotels and car rental agencies with which we have marketing agreements to sell mileage credits. Our contracts to sell mileage credits under these marketing agreements have multiple deliverables, as defined below.

Our most significant contract to sell mileage credits relates to our co-brand credit card relationship with American Express. Our agreements with American Express provide for joint marketing, grant certain benefits to Delta-American Express co-branded credit card holders ("Cardholders") and American Express Membership Rewards program participants and allow American Express to market using our customer database. Cardholders earn mileage credits for making purchases using co-branded cards, may check their first bag for free, are granted discounted access to Delta Sky Club lounges and receive other benefits while traveling on Delta. These benefits that we provide in the form of separate products and services under the SkyMiles agreements are referred to as "deliverables." Additionally, participants in the American Express Membership Rewards program may exchange their points for mileage credits under the SkyMiles program. As a result, we sell mileage credits at agreed-upon rates to American Express for provision to their customers under the co-brand credit card program and the Membership Rewards program.

Our marketing agreements with American Express extend to 2022. We account for the agreements consistent with the accounting method that allocates the consideration received to the individual products and services delivered based on their relative selling prices. We determined our best estimate of the selling prices by considering discounted cash flow analysis using multiple inputs and assumptions, including: (1) the expected number of miles awarded and number of miles redeemed, (2) the rate at which we sell mileage credits to other airlines, (3) published rates on our website for baggage fees, discounted access to Delta Sky Club lounges and other benefits while traveling on Delta and (4) brand value.

We recognize revenue as we deliver each sales element. We defer the travel deliverable (mileage credits) as part of frequent flyer deferred revenue and recognize passenger revenue as the mileage credits are used for travel. The revenue allocated to the remaining deliverables is recorded in other revenue. We recognize the revenue for these services as they are performed.

Breakage. For mileage credits that we estimate are not likely to be redeemed ("breakage"), we recognize the associated value proportionally during the period in which the remaining mileage credits are expected to be redeemed. Management uses statistical models to estimate breakage based on historical redemption patterns. A change in assumptions as to the period over which mileage credits are expected to be redeemed, the actual redemption activity for mileage credits or the estimated fair value of mileage credits expected to be redeemed could have a material impact on our revenue in the year in which the change occurs and in future years.



## Table of Contents

## Regional Carriers Revenue

Our regional carriers include both our contract carrier agreements with third-party regional carriers ("contract carriers") and Endeavor Air, Inc. ("Endeavor"), our wholly owned subsidiary. Our contract carrier agreements are structured as either (1) capacity purchase agreements where we purchase all or a portion of the contract carrier's capacity and are responsible for selling the seat inventory we purchase or (2) revenue proration agreements, which are based on a fixed dollar or percentage division of revenues for tickets sold to passengers traveling on connecting flight itineraries. We record revenue related to our contract carriers and Endeavor in regional carriers passenger revenue and the related expenses in regional carriers expense.

## Cargo Revenue

Cargo revenue is recognized when we provide the transportation.

## Other Revenue

Other revenue is primarily comprised of (1) loyalty programs, (2) administrative fees, club and on-board sales, (3) ancillary businesses and refinery and (4) baggage fees.

## Manufacturers' Credits

We periodically receive credits in connection with the acquisition of aircraft and engines. These credits are deferred until the aircraft and engines are delivered, and then applied as a reduction to the cost of the related equipment.

## Maintenance Costs

We record maintenance costs to aircraft maintenance materials and outside repairs. Maintenance costs are expensed as incurred, except for costs incurred under power-by-the-hour contracts, which are expensed based on actual hours flown. Power-by-the-hour contracts transfer certain risk to third-party service providers and fix the amount we pay per flight hour to the service provider in exchange for maintenance and repairs under a predefined maintenance program. Modifications that enhance the operating performance or extend the useful lives of airframes or engines are capitalized and amortized over the remaining estimated useful life of the asset or the remaining lease term, whichever is shorter.

## Advertising Costs

We expense advertising costs in passenger commissions and other selling expenses in the year incurred. Advertising expense was $284 million, $277 million and $230 million for the years ended December 31, 2017, 2016 and 2015, respectively.

## Commissions

Passenger sales commissions are recognized in operating expense when the related revenue is recognized.



## NOTE 2. FAIR VALUE MEASUREMENTS

Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or liability.

• Level 1. Observable inputs such as quoted prices in active markets;

• Level 2. Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

• Level 3. Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Assets and liabilities measured at fair value are based on the valuation techniques identified in the tables below. The valuation techniques are as follows:

(a) Market approach. Prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities; and

(b) Income approach. Techniques to convert future amounts to a single present value amount based on market expectations (including present value techniques and option-pricing models).

## Table of Contents

Cash Equivalents and Restricted Cash Equivalents and Investments. Cash equivalents generally consist of money market funds. Restricted cash equivalents and investments generally consist of money market funds and time deposits, which primarily support letters of credit that relate to certain projected self-insurance obligations and airport commitments. The fair value of these investments is based on a market approach using prices and other relevant information generated by market transactions involving identical or comparable assets.

Short-Term Investments. The fair values of short-term investments are based on a market approach using industry standard valuation techniques that incorporate observable inputs such as quoted market prices, interest rates, benchmark curves, credit ratings of the security and other observable information.

Long-Term Investments. Our long-term investments that have historically been measured at fair value primarily consist of equity investments in Grupo Aeroméxico, the parent company of Aeroméxico, and the parent company of GOL. During 2017, we completed a tender offer for additional shares of Grupo Aeroméxico. With the completion of the tender offer, our investment is accounted for under the equity method and is no longer measured at fair value on a recurring basis. As of December 31, 2017, our long-term investments include our shares in China Eastern and the parent company of GOL. Our investments are valued based on market prices and are classified in other noncurrent assets.

Hedge Derivatives. A portion of our derivative contracts are negotiated over-the-counter with counterparties without going through a public exchange. Accordingly, our fair value assessments give consideration to the risk of counterparty default (as well as our own credit risk). Such contracts are classified as Level 2 within the fair value hierarchy. The remainder of our hedge contracts are comprised of futures contracts, which are traded on a public exchange. These contracts are classified within Level 1 of the fair value hierarchy.

Fuel Contracts. Our fuel hedge portfolio consists of options, swaps and futures. The hedge contracts include crude oil and refined products, as these commodities are highly correlated with the price of fuel that we consume. Option contracts are valued under an income approach using option pricing models based on data either readily observable in public markets, derived from public markets or provided by counterparties who regularly trade in public markets. Volatilities used in these valuations ranged from 10% to 28% depending on the maturity dates, underlying commodities and strike prices of the option contracts. Swap contracts are valued under an income approach using a discounted cash flow model based on data either readily observable or provided by counterparties who regularly trade in public markets. Discount rates used in these valuations vary based on maturity dates utilizing the London interbank offered rate ("LIBOR"). Futures contracts and options on futures contracts are traded on a public exchange and valued based on quoted market prices.

• Foreign Currency Exchange Contracts. Our foreign currency derivatives consist of Japanese yen and Canadian dollar forward contracts and are valued based on data readily observable in public markets.

## Long-Term Investments

We have developed strategic relationships with certain airlines through equity investments and other forms of cooperation and support. Strategic relationships improve our coordination with these airlines and enable our customers to seamlessly connect to more places while enjoying a consistent, high-quality travel experience.

## Equity Method Investments

• Aroméxico . During 2017, we completed a $622 million tender offer and executed derivative contracts for $173 million to obtain additional capital stock of Grupo Aeroméxico, increasing our ownership percentage to a non-controlling 49% equity stake in Grupo Aeroméxico.

• Virgin Atlantic . We have a non-controlling 49% equity stake in Virgin Atlantic Limited, the parent company of Virgin Atlantic Airways.

We account for these investments under the equity method of accounting and recognize our portion of their financial results in miscellaneous, net in our Consolidated Statements of Operations.

## Available-for-Sale Investments

- GOL. We own 9% of the outstanding capital stock of GOL's parent company through ownership of its preferred shares. Driven by an improved outlook for the Brazilian economy and the financial performance of the company, the stock price of GOL's parent company has more than doubled since December 31, 2016 and exceeds the original cost of our investment. This unrealized gain of $56 million is recorded in AOCI.

Additionally, GOL has a $300 million five-year term loan facility with third parties, which we have guaranteed. Our entire guaranty is secured by GOL's ownership interest in Smiles, GOL's publicly-traded loyalty program. Because GOL remains in compliance with the terms of its loan facility, we have not recorded a liability on our Consolidated Balance Sheets as of December 31, 2017.

- China Eastern. We have a 3% equity interest in China Eastern. Because the investment agreement with China Eastern restricts our sale or transfer of these shares through the September 2018 quarter, we had previously recorded this investment at cost. As we are now within one year of the lapse of these restrictions, we began accounting for the investment during the September 2017 quarter as available-for-sale with changes in fair value recorded in AOCI. As of December 31, 2017, the unrealized gain recorded in AOCI was $106 million.

## Cost Method Investments

- Air France-KLM. During 2017, we acquired 10% of the outstanding shares of our joint venture partner, Air France-KLM, for $450 million. Because our investment agreement restricts the sale or transfer of these shares for five years, we account for this investment at cost. We are working to develop a combined long-term joint venture with Air France-KLM and Virgin Atlantic as part of our investment strategy.

- Republic Airways . During 2017, we acquired a 17% ownership interest in Republic Airways Holdings Inc. ("Republic"), in consideration for our unsecured claim in Republic's bankruptcy case. This ownership interest is accounted for at cost as Republic's shares are not actively traded on a public exchange and we do not have the ability to exercise significant influence over Republic.



## NOTE 4 . DERIVATIVES AND RISK MANAGEMENT

Changes in fuel prices, interest rates and foreign currency exchange rates impact our results of operations. In an effort to manage our exposure to these risks, we may enter into derivative contracts and adjust our derivative portfolio as market conditions change.

## Fuel Price Risk

Changes in fuel prices materially impact our results of operations. We have recently managed our fuel price risk through a hedging program intended to reduce the financial impact from changes in the price of fuel as fuel prices are subject to potential volatility. In addition, we may enter into derivatives with third parties to hedge financial risk related to Monroe’s refining margins.

In response to this volatility, during 2015 and 2016 we entered into transactions to defer settlement of a portion of our hedge portfolio and lock in the amount of hedge settlements for a portion of 2016 and 2017. These deferral transactions, excluding markets movements from the date of inception, provided approximately $300 million in cash receipts in 2015 and 2016 and required approximately $300 million in cash payments in 2016 and 2017. We also early settled $455 million of our airline segment's 2016 positions during 2016. Cash flows associated with the deferral transactions are reported as cash flows from financing activities within our Consolidated Statements of Cash Flows.

During the years ended December 31, 2017, 2016 and 2015, we recorded fuel hedge losses of $81 million, $366 million and $741 million, respectively.

## Interest Rate Risk

Our exposure to market risk from adverse changes in interest rates is primarily associated with our long-term debt obligations. Market risk associated with our fixed and variable rate long-term debt relates to the potential reduction in fair value and negative impact to future earnings, respectively, from an increase in interest rates.

In an effort to manage our exposure to the risk associated with our variable rate long-term debt, we periodically enter into interest rate swaps. We designate interest rate contracts used to convert the interest rate exposure on a portion of our debt portfolio from a floating rate to a fixed rate as cash flow hedges, while those contracts converting our interest rate exposure from a fixed rate to a floating rate are designated as fair value hedges.

We also have exposure to market risk from adverse changes in interest rates associated with our cash and cash equivalents and benefit plan obligations. Market risk associated with our cash and cash equivalents relates to the potential decline in interest income from a decrease in interest rates. Pension, postretirement, postemployment and worker's compensation obligation risk relates to the potential increase in our future obligations and expenses from a decrease in interest rates used to discount these obligations.

## Foreign Currency Exchange Rate Risk

We are subject to foreign currency exchange rate risk because we have revenue and expense denominated in foreign currencies with our primary exposures being the Japanese yen and Canadian dollar. To manage exchange rate risk, we execute both our international revenue and expense transactions in the same foreign currency to the extent practicable. From time to time, we may also enter into foreign currency option and forward contracts. These foreign currency exchange contracts are designated as cash flow hedges.

(1) As discussed above, we early settled $455 million of our airline segment's 2016 fuel hedge positions and entered into hedges designed to offset and effectively neutralize our 2017 airline segment hedge positions. The dollar amounts shown above primarily represent the offsetting derivatives that were used to neutralize the 2016 and 2017 airline segment hedge portfolio.

## Offsetting Assets and Liabilities

We have master netting arrangements with our counterparties giving us the right to offset hedge assets and liabilities. However, we have elected not to offset the fair value positions recorded on our Consolidated Balance Sheets. The following table shows the net fair value of our counterparty positions had we elected to offset.

## Table of Contents

## Credit Risk

To manage credit risk associated with our fuel price, interest rate and foreign currency hedging programs, we evaluate counterparties based on several criteria including their credit ratings and limit our exposure to any one counterparty.

Our hedge contracts contain margin funding requirements. The margin funding requirements may cause us to post margin to counterparties or may cause counterparties to post margin to us as market prices in the underlying hedged items change. Due to the fair value position of our hedge contracts, we posted margin of $43 million and $38 million as of December 31, 2017 and 2016, respectively.

Our accounts receivable are generated largely from the sale of passenger airline tickets and cargo transportation services, the majority of which are processed through major credit card companies. We also have receivables from the sale of mileage credits under our SkyMiles program to participating airlines and non-airline businesses such as credit card companies, hotels and car rental agencies. The credit risk associated with our receivables is minimal.

## Self-Insurance Risk

We self-insure a portion of our losses from claims related to workers' compensation, environmental issues, property damage, medical insurance for employees and general liability. Losses are accrued based on an estimate of the aggregate liability for claims incurred, using independent actuarial reviews based on standard industry practices and our historical experience.

(1) Guaranteed by substantially all of our domestic subsidiaries (the "Guarantors").

(2) Borrowings must be repaid annually in an amount equal to 1% per year of the original principal amount (paid in equal quarterly installments), with the balance due on the final maturity date.

(3) Due in installments.

(4) Interest rate equal to LIBOR (generally subject to a floor) or another index rate, in each case plus a specified margin. Additionally, certain aircraft and other financings are comprised of variable rate debt.

(5) Includes notes issued in March and December 2017.

(6) Primarily includes unsecured bonds and debt secured by certain accounts receivable and real estate.

## Unsecured Debt Offerings

During the March 2017 quarter, we issued $2.0 billion in aggregate principal amount of unsecured notes, consisting of $1.0 billion of 2.875% Notes due 2020 and $1.0 billion of 3.625% Notes due 2022. During the December 2017 quarter, we issued $450 million in aggregate principal amount of 2.600% Notes due 2020 (collectively, the "Notes"). The Notes are equal in priority with all of our other unsubordinated indebtedness and senior in priority to all of our future subordinated debt.

The Notes are subject to covenants that, among other things, limit our ability to incur liens securing indebtedness for borrowed money or capital leases and engage in mergers and consolidations or transfer all or substantially all of our assets, in each case subject to certain exceptions. The Notes are also subject to customary event of default provisions, including cross-defaults to other material indebtedness.

If we experience certain changes of control and a ratings decline on any series of Notes by two of the ratings agencies to a rating below investment grade within a certain period of time following a change of control or public notice of the occurrence of a change of control, we must offer to repurchase such series.

## Key Financial Covenants

We were in compliance with the covenants in our financing agreements at December 31, 2017.



## Table of Contents

Pacific Facilities. Our obligations under the Pacific Facilities are secured by a first lien on our Pacific route authorities and certain related assets. The Pacific Facilities include affirmative, negative and financial covenants that could restrict our ability to, among other things, make investments, sell or otherwise dispose of collateral if we are not in compliance with the collateral coverage ratio tests described below, pay dividends or repurchase stock.

<table><tr><td>Minimum fixed charge coverage ratio (1)</td><td>1.20:1</td></tr><tr><td>Minimum unrestricted liquidity</td><td></td></tr><tr><td>Unrestricted cash, permitted investments and undrawn revolving credit facilities</td><td>$2.0 billion</td></tr><tr><td>Minimum collateral coverage ratio (2)</td><td>1.60:1</td></tr></table>

(1) Defined as the ratio of (a) earnings before interest, taxes, depreciation, amortization and aircraft rent and other adjustments to net income to (b) the sum of gross cash interest expense (including the interest portion of our capitalized lease obligations) and cash aircraft rent expense, for the 12-month period ending as of the last day of each fiscal quarter.

(2) Defined as the ratio of (a) certain of the collateral that meet specified eligibility standards to (b) the sum of the aggregate outstanding obligations and certain other obligations.

2015 Credit Facilities. Our obligations under the 2015 Credit Facilities are secured by liens on certain of our and the Guarantors' assets, including accounts receivable, aircraft, spare engines, non-Pacific international routes, domestic slots and certain investment property. The 2015 Credit Facilities include affirmative, negative and financial covenants that may restrict our ability to, among other things, make investments, sell or otherwise dispose of assets if not in compliance with the collateral coverage ratio tests, pay dividends or repurchase stock. These covenants require us to maintain:

<table><tr><td colspan="2">Minimum unrestricted liquidity</td></tr><tr><td>Unrestricted cash, permitted investments and undrawn revolving credit facilities</td><td>$2.0 billion</td></tr><tr><td>Minimum collateral coverage ratio (1)</td><td>1.60:1</td></tr></table>

(1) Defined as the ratio of (a) certain of the collateral that meet specified eligibility standards to (b) the sum of the aggregate outstanding obligations under the 2015 Credit Facilities and certain other obligations.

Under the 2015 Credit Facilities, if the Minimum Collateral Coverage Ratio is not maintained, we must either provide additional collateral to secure our obligations, or we must reduce the secured obligations under the facilities by an amount necessary to maintain compliance with the collateral coverage ratio. The 2015 Credit Facilities contain events of default customary for similar financings, including cross-defaults to other material indebtedness and certain change of control events. Upon the occurrence of an event of default, the outstanding obligations under the 2015 Credit Facilities may be accelerated and become due and payable immediately.

## Fair Value of Debt

Market risk associated with our fixed- and variable-rate long-term debt relates to the potential reduction in fair value and negative impact to future earnings, respectively, from an increase in interest rates. The fair value of debt, shown below, is principally based on reported market values, recently completed market transactions and estimates based on interest rates, maturities, credit risk and underlying collateral. Long-term debt is primarily classified as Level 2 within the fair value hierarchy.

## NOTE 7 . LEASE OBLIGATIONS

We lease aircraft, airport terminals, maintenance facilities, ticket offices and other property and equipment from third parties. Rental expense for operating leases, which is recorded on a straight-line basis over the life of the lease term, totaled $1.3 billion for the years ended December 31, 2017 and 2016 and $1.2 billion for the year ended December 31, 2015. Amounts due under capital leases are recorded as liabilities, while assets acquired under capital leases are recorded as property and equipment. Amortization of assets recorded under capital leases is included in depreciation and amortization expense. Our airport terminal leases include contingent rents, which vary based upon facility usage, enplanements, aircraft weight and other factors. Many of our aircraft, facility and equipment leases include rental escalation clauses and/or renewal options. Our leases do not include residual value guarantees and we are not the primary beneficiary in or have other forms of variable interest with the lessor of the leased assets. As a result, we have not consolidated any of the entities that lease to us.



## Table of Contents

The following tables summarize our minimum rental commitments under capital leases and noncancelable operating leases (including certain aircraft flown by regional carriers) with initial or remaining terms in excess of one year for the years succeeding December 31, 2017:

## NOTE 8. AIRPORT REDEVELOPMENT

## New York-JFK Airport

In 2015, we completed our redevelopment project at New York-JFK's Terminal 4 to facilitate convenient connections for our passengers and improve coordination with our SkyTeam alliance partners. Terminal 4 is operated by JFK International Air Terminal LLC ("IAT"), a private party, under its lease with the Port Authority of New York and New Jersey ("Port Authority"). In December 2010, we entered into a 33-year agreement with IAT ("Sublease") to sublease space in Terminal 4. Also, in 2010, the Port Authority issued approximately $800 million principal amount of special project bonds to fund the majority of the project.

We managed the project and bore the construction risk, including cost overruns. We recorded an asset for project costs (e.g., design, permitting, labor and other general construction costs), regardless of funding source, and a construction obligation equal to project costs funded by parties other than us. Our rental payments reduce the construction obligation and result in the recording of interest expense, calculated using the effective interest method. As of December 31, 2017, we have recorded $691 million as property and equipment and $744 million as the related construction obligation.



## Table of Contents

We have an equity method investment in the entity which owns IAT, our sublessor at Terminal 4. The Sublease requires us to pay certain fixed management fees. We determined the investment is a variable interest entity and assessed whether we have a controlling financial interest in IAT. Our rights under the Sublease, with respect to management of Terminal 4, are consistent with rights granted to an anchor tenant under a standard airport lease. Accordingly, we do not consolidate the entity in which we have an investment in our Consolidated Financial Statements.

## Los Angeles International Airport

During 2016, we announced plans to modernize, upgrade and connect Terminals 2 and 3 at Los Angeles International Airport (“LAX”) over the next seven years. A substantial majority of the project costs will be funded through the Regional Airports Improvement Corporation ("RAIC"), a California public benefit corporation, using an $800 million revolving credit facility provided by a group of lenders. The credit facility was executed during 2017. We have guaranteed the obligations of the RAIC under the credit facility. Because the RAIC remains in compliance with the terms of its credit facility, we have not recorded a liability on our Consolidated Balance Sheet as of December 31, 2017.

## New York-LaGuardia Airport

As part of the terminal redevelopment project at LaGuardia Airport, we are partnering with the Port Authority of New York and New Jersey (the "Port Authority") to replace Terminals C and D with a new state-of-the-art terminal facility consisting of 37 gates across four concourses connected to a central headhouse. The terminal will feature a new, larger Delta Sky Club, wider concourses, more gate seating and 30 percent more concessions space than the existing terminals. The facility will also offer direct access between the parking garage and terminal with improved roadways and drop-off/pick-up areas. The design of the new terminal will integrate sustainable technologies and improved energy efficiency. Construction will be phased to limit passenger inconvenience and is expected to be completed by 2026.

In connection with the redevelopment, during 2017, we entered into an amended and restated terminal lease with the Port Authority with a term through 2050. Pursuant to the lease agreement we will (1) fund (through debt issuance and existing cash) and undertake the design, management and construction of the terminal and certain off-premises supporting facilities, (2) receive a Port Authority contribution of $600 million to facilitate construction of the terminal and other supporting infrastructure, (3) be responsible for all operations and maintenance during the term of the lease and (4) have preferential rights to all gates in the terminal subject to Port Authority requirements with respect to accommodation of designated carriers.

## NOTE 9. EMPLOYEE BENEFIT PLANS

We sponsor defined benefit and defined contribution pension plans, healthcare plans and disability and survivorship plans for eligible employees and retirees and their eligible family members.

Defined Benefit Pension Plans. We sponsor defined benefit pension plans for eligible employees and retirees. These plans are closed to new entrants and frozen for future benefit accruals. The Pension Protection Act of 2006 allows commercial airlines to elect alternative funding rules ("Alternative Funding Rules") for defined benefit plans that are frozen. We elected the Alternative Funding Rules under which the unfunded liability for a frozen defined benefit plan may be amortized over a fixed 17-year period and is calculated using an 8.85% discount rate. We have no minimum funding requirements in 2018. However, in January 2018, we voluntarily contributed approximately $500 million to these plans.

Defined Contribution Pension Plans. We sponsor several defined contribution plans. These plans generally cover different employee groups and employer contributions vary by plan. The costs associated with our defined contribution pension plans were $875 million, $733 million and $592 million for the years ended December 31, 2017, 2016 and 2015, respectively.

Postretirement Healthcare Plans. We sponsor healthcare plans that include providing benefits to eligible retirees and their dependents who are under age 65. We have generally eliminated company-paid post age 65 healthcare coverage, except for (1) subsidies available to a limited group of retirees and their dependents and (2) a group of retirees who retired prior to 1987. Benefits under these plans are funded from current assets and employee contributions.

Postemployment Plans. We provide certain other welfare benefits to eligible former or inactive employees after employment but before retirement, primarily as part of the disability and survivorship plans. Substantially all employees are eligible for benefits under these plans in the event of death and/or disability.

(1) At the end of each year presented, our accumulated benefit obligations for our pension plans are equal to the benefit obligations shown above.

During 2017 and 2016, net actuarial losses increased our benefit obligation due to the decrease in discount rates. These gains and losses are recorded in AOCI and reflected in the table below.

A net actuarial loss of $277 million will be amortized from AOCI into net periodic benefit cost in 2018. Amounts are generally amortized from AOCI over the expected future lifetime of plan participants.

(1) See Note 1 for discussion on ASU No. 2017-07, "Compensation - Retirement Benefits (Topic 715)."

## Assumptions

We used the following actuarial assumptions to determine our benefit obligations and our net periodic cost for the periods presented:

<table><tr><td rowspan="2">Benefit Obligations (1)</td><td colspan="2">December 31,</td></tr><tr><td>2017</td><td>2016</td></tr><tr><td>Weighted average discount rate</td><td>3.69%</td><td>4.20%</td></tr></table>

<table><tr><td rowspan="2">Net Periodic Cost (1)</td><td colspan="3">Year Ended December 31,</td></tr><tr><td>2017</td><td>2016</td><td>2015</td></tr><tr><td>Weighted average discount rate - pension benefit</td><td>4.14%</td><td>4.57%</td><td>4.13%</td></tr><tr><td>Weighted average discount rate - other postretirement benefit</td><td>4.19%</td><td>4.53%</td><td>4.13%</td></tr><tr><td>Weighted average discount rate - other postemployment benefit</td><td>4.14%</td><td>4.50%</td><td>4.13%</td></tr><tr><td>Weighted average expected long-term rate of return on plan assets</td><td>8.96%</td><td>8.94%</td><td>8.94%</td></tr><tr><td>Assumed healthcare cost trend rate (2)</td><td>7.00%</td><td>6.50%</td><td>7.00%</td></tr></table>

(1) Future employee compensation levels do not impact our frozen defined benefit pension plans or other postretirement plans and impact only a small portion of our other postemployment liability.

(2) Healthcare cost trend rate at December 31, 2017 is assumed to decline gradually to 5.00% by 2026 and remain unchanged thereafter.



Healthcare Cost Trend Rate. Assumed healthcare cost trend rates have an effect on the amounts reported for the other postretirement benefit plans. A 1% change in the healthcare cost trend rate used in measuring the plan benefit obligation for these plans would have the following effects:

<table><tr><td>(in millions)</td><td>1% Increase</td><td>1% (Decrease)</td></tr><tr><td>Increase (decrease) in total service and interest cost</td><td>1 $</td><td>(1)</td></tr><tr><td>Increase (decrease) in the accumulated plan benefit obligation</td><td>9</td><td>(30)</td></tr></table>

Expected Long-Term Rate of Return. Our expected long-term rate of return on plan assets is based primarily on plan-specific investment studies using historical market return and volatility data. Modest excess return expectations versus some public market indices are incorporated into the return projections based on the actively managed structure of the investment programs and their records of achieving such returns historically. We also expect to receive a premium for investing in less liquid private markets. We review our rate of return on plan assets assumptions annually. Our annual investment performance for one particular year does not, by itself, significantly influence our evaluation. The investment strategy for our defined benefit pension plan assets is to earn a long-term return that meets or exceeds our annualized return target while taking an acceptable level of risk and maintaining sufficient liquidity to pay current benefits and other cash obligations of the plan. This is achieved by investing in a globally diversified mix of public and private equity, fixed income, real assets, hedge funds and other assets and instruments. Our expected long-term rate of return on assets for net periodic pension benefit cost for the year ended December 31, 2017 was 8.96%.

Life Expectancy. Changes in life expectancy may significantly change our benefit obligations and future expense. We use the Society of Actuaries ("SOA") published mortality data, other publicly available information and our own perspective of future longevity to develop our best estimate of life expectancy. The SOA publishes annual updated mortality tables for U.S. plans and updated improvement scale. Each year we consider updates by the SOA in setting our mortality assumptions for purposes of measuring pension and other postretirement and postemployment benefit obligations.

## Benefit Payments

Benefit payments in the table below are based on the same assumptions used to measure the related benefit obligations. Actual benefit payments may vary significantly from these estimates. Benefits earned under our pension plans and certain postemployment benefit plans are expected to be paid from funded benefit plan trusts, while our other postretirement benefits are funded from current assets.

The following table summarizes the benefit payments that are scheduled to be paid in the years ending December 31:

<table><tr><td>(in millions)</td><td>Pension Benefits</td><td>Other Postretirement and Postemployment Benefits</td></tr><tr><td>2018</td><td>1,170</td><td>284</td></tr><tr><td>2019</td><td>1,177</td><td>291</td></tr><tr><td>2020</td><td>1,201</td><td>296</td></tr><tr><td>2021</td><td>1,220</td><td>297</td></tr><tr><td>2022</td><td>1,238</td><td>296</td></tr><tr><td>2023-2027</td><td>6,351</td><td>1,417</td></tr></table>

## Plan Assets

We have adopted and implemented investment policies for our defined benefit pension plans that incorporate strategic asset allocation mixes intended to best meet the plans' long-term obligations, while maintaining an appropriate level of risk and liquidity. These asset portfolios employ a diversified mix of investments, which are reviewed periodically. Active management strategies are utilized where feasible in an effort to realize investment returns in excess of market indices. Derivatives in the plans are primarily used to manage risk and gain asset class exposure while still maintaining liquidity. As part of these strategies, the plans are required to hold cash collateral associated with certain derivatives. Our investment strategies target a mix of 40 - 50% growth-seeking assets, 20 - 30% income-generating assets and 25 - 30% risk-diversifying assets. Risk diversifying assets include hedged mandates implementing long-short, market neutral and relative value strategies that invest primarily in publicly-traded equity, fixed income, foreign currency and commodity securities and are used to improve the impact of active management on the plans.

## Benefit Plan Assets Measured at Fair Value on a Recurring Basis

Benefit Plan Assets. Benefit plan assets relate to our defined benefit pension plans and certain of our postemployment benefit plans. These investments are presented net of the related benefit obligation in pension, postretirement and related benefits on the Consolidated Balance Sheets. See Note 2 of the Notes to the Consolidated Financial Statements for a description of the levels within the fair value hierarchy and associated valuation techniques used to measure fair value. The following table shows our benefit plan assets by asset class.

<table><tr><td rowspan="2">(in millions)</td><td colspan="3">December 31, 2017</td><td colspan="3">December 31, 2016</td><td rowspan="2">Valuation Technique</td></tr><tr><td>Level 1</td><td>Level 2</td><td>Total</td><td>Level 1</td><td>Level 2</td><td>Total</td></tr><tr><td>Equities and equity-related instruments</td><td>$ 2,033</td><td>$ 13</td><td>$ 2,046</td><td>$ 2,021</td><td>$ 14</td><td>$ 2,035</td><td>(a)</td></tr><tr><td>Delta common stock</td><td>801</td><td>—</td><td>801</td><td>386</td><td>—</td><td>386</td><td>(a)</td></tr><tr><td>Cash equivalents</td><td>735</td><td>697</td><td>1,432</td><td>228</td><td>1,240</td><td>1,468</td><td>(a)</td></tr><tr><td>Fixed income and fixed income-related instruments</td><td>17</td><td>3,648</td><td>3,665</td><td>8</td><td>1,190</td><td>1,198</td><td>(a)(b)</td></tr><tr><td>Benefit plan assets</td><td>$ 3,586</td><td>$ 4,358</td><td>$ 7,944</td><td>$ 2,643</td><td>$ 2,444</td><td>$ 5,087</td><td></td></tr><tr><td>Investments measured at net asset value ("NAV") (1)</td><td></td><td></td><td>$ 7,378</td><td></td><td></td><td>$ 5,724</td><td></td></tr><tr><td>Total benefit plan assets</td><td></td><td></td><td>$ 15,322</td><td></td><td></td><td>$ 10,811</td><td></td></tr></table>

(1) Investments that were measured at NAV per share (or its equivalent) as a practical expedient have not been classified in the fair value hierarchy.

Equities and Equity-Related Instruments. Investments include common stock and equity-related instruments. Common stock is valued at the closing price reported on the active market on which the individual securities are traded. Equity-related instruments include investments in securities traded on exchanges, including listed futures and options, which are valued at the last reported sale prices on the last business day of the year or, if not available, the last reported bid prices. Over-the-counter securities are valued at the bid prices or the average of the bid and ask prices on the last business day of the year from published sources or, if not available, from other sources considered reliable, generally broker quotes.

Delta Common Stock. In each of 2017 and 2016, we contributed $350 million of Delta common stock as a portion of the employer contribution to certain of its defined benefit pension plans. The Delta common stock investment is managed by an independent fiduciary.

Cash Equivalents. These investments primarily consist of high-quality, short-term obligations that are a part of institutional money market mutual funds that are calculated using current market quotations or an appropriate substitute that reflects current market conditions.

Fixed Income and Fixed Income-Related Instruments. Investments include corporate bonds, government bonds, collateralized mortgage obligations and other asset-backed securities. These investments are generally valued at the bid price or the average of the bid and ask price. Prices are based on pricing models, quoted prices of securities with similar characteristics, or broker quotes. Fixed income-related instruments include investments in securities traded on exchanges, including listed futures and options, which are valued at the last reported sale prices on the last business day of the year, or if not available, the last reported bid prices. Over-the-counter securities are valued at the bid prices or the average of the bid and ask prices on the last business day of the year from published sources or, if not available, from other sources considered reliable, generally broker quotes.



The following table summarizes investments measured at fair value based on NAV per share as a practical expedient:

(1) Monthly

(2) Semi-monthly

(3) Semi-annually

(4) Annually

(5) Various. Includes funds with weekly, monthly, semi-monthly, quarterly and custom redemption frequencies as well as funds with a redemption window following the anniversary of the initial investment.

Hedge Funds and Hedge Fund-Related Strategies. These investments are primarily made through shares of limited partnerships or similar structures for which a liquid secondary market does not exist. These funds are typically valued monthly by third-party administrators that have been appointed by the funds' general partners.

Commingled Funds, Private Equity and Private Equity-Related Instruments. Investments include commingled funds invested in common stock, as well as private equity and private equity-related instruments. Commingled funds are based on quoted market prices of the underlying assets owned by the fund. Private equity and private equity-related strategies are valued based on valuation models where one or more of the significant inputs into the model cannot be observed and which require the development of assumptions.

Fixed Income and Fixed Income-Related Instruments. Investments include commingled funds invested in debt obligations. Commingled funds are based on quoted market prices of the underlying assets owned by the fund.

Real Assets. These investments include real estate, energy, timberland, agriculture and infrastructure. The valuation of real assets requires significant judgment due to the absence of quoted market prices as well as the inherent lack of liquidity and the long-term nature of these assets. Investments are valued based on valuation models where one or more of the significant inputs into the model cannot be observed and which require the development of assumptions.

Other. Primarily includes globally-diversified, risk-managed commingled funds consisting mainly of equity, fixed income and commodity exposures.

On an annual basis we assess the potential for adjustments to the fair value of all investments. Certain of our investments are valued using NAV as a practical expedient due to the lag in the availability of data. This primarily applies to private equity, private equity-related strategies and real assets. We solicit valuation updates from the investment managers and use their information and corroborating data from public markets to determine any needed fair value adjustments.

## Other

We also sponsor defined benefit pension plans for eligible employees in certain foreign countries. These plans did not have a material impact on our Consolidated Financial Statements in any period presented.



## Table of Contents

## Profit Sharing Program

Our broad-based employee profit sharing program provides that, for each year in which we have an annual pre-tax profit, as defined by the terms of the program, we will pay a specified portion of that profit to employees. In determining the amount of profit sharing, the program defines profit as pre-tax profit adjusted for profit sharing and certain other items. For the years ended December 31, 2017, 2016 and 2015, we recorded expenses of $1.1 billion, $1.1 billion and $1.5 billion under the profit sharing program, respectively.

Effective October 1, 2017, we aligned our profit sharing plans under a single formula. Under this formula, our profit sharing program pays 10% to all eligible employees for the first $2.5 billion of annual profit and 20% of annual profit above $2.5 billion. Prior to that time, the profit sharing program for pilots used this formula but for 2016 and the first nine months of 2017, the profit sharing program for merit, ground and flight attendant employees paid 10% of annual profit (as defined by the terms of the program) and, if we exceeded our prior-year results, the program paid 20% of the year-over-year increase in profit to eligible employees. For years prior to 2016, the profit sharing program for merit, ground and flight attendant employees paid according to the current formula. Going forward, all eligible employees will be paid profit sharing under the current formula.

## NOTE 10. COMMITMENTS AND CONTINGENCIES

## Aircraft Purchase and Lease Commitments

Our future aircraft purchase commitments totaled approximately $18.3 billion at December 31, 2017 :

<table><tr><td>(in millions)</td><td>Total</td></tr><tr><td>2018</td><td>$ 3,570</td></tr><tr><td>2019</td><td>3,370</td></tr><tr><td>2020</td><td>3,270</td></tr><tr><td>2021</td><td>3,880</td></tr><tr><td>2022</td><td>2,450</td></tr><tr><td>Thereafter</td><td>1,740</td></tr><tr><td>Total</td><td>$ 18,280</td></tr></table>

Our future aircraft purchase commitments included the following aircraft at December 31, 2017:

<table><tr><td>Aircraft Type</td><td>Purchase Commitments</td></tr><tr><td>A321-200</td><td>93</td></tr><tr><td>A321-200neo</td><td>100</td></tr><tr><td>A330-900neo</td><td>25</td></tr><tr><td>A350-900</td><td>19</td></tr><tr><td>B-737-900ER</td><td>41</td></tr><tr><td>CS100</td><td>75</td></tr><tr><td>Total</td><td>353</td></tr></table>

During 2017, we entered into agreements with Airbus to place an expanded A321-200 order for 45 firm additional aircraft and to defer 10 of our A350-900 aircraft deliveries set for 2019-2020 by two to three years. We also entered into an agreement with Airbus to order 100 A321-200neo aircraft to start delivery in 2020 with the option to purchase an additional 100 A321-200neo aircraft.



## Contract Carrier Agreements

We have contract carrier agreements with regional carriers expiring from 2018 to 2027.

Capacity Purchase Agreements. Most of our contract carriers operate for us under capacity purchase agreements. Under these agreements, the contract carriers operate some or all of their aircraft using our flight designator codes, and we control the scheduling, pricing, reservations, ticketing and seat inventories of those aircraft and retain the revenues associated with those flights. We pay those airlines an amount, as defined in the applicable agreement, which is based on a determination of their cost of operating those flights and other factors intended to approximate market rates for those services.

The following table shows our minimum fixed obligations under our existing capacity purchase agreements with third-party regional carriers. The obligations set forth in the table contemplate minimum levels of flying by the contract carriers under the respective agreements and also reflect assumptions regarding certain costs associated with the minimum levels of flying such as the cost of fuel, labor, maintenance, insurance, catering, property tax and landing fees. Accordingly, our actual payments under these agreements could differ materially from the minimum fixed obligations set forth in the table below.

<table><tr><td colspan="2">(in millions)</td><td colspan="2">Amount  \( {}^{(1)} \)</td></tr><tr><td>2018</td><td></td><td>$</td><td>1,772</td></tr><tr><td>2019</td><td></td><td></td><td>1,603</td></tr><tr><td>2020</td><td></td><td></td><td>1,320</td></tr><tr><td>2021</td><td></td><td></td><td>793</td></tr><tr><td>2022</td><td></td><td></td><td>723</td></tr><tr><td>Thereafter</td><td></td><td></td><td>1,975</td></tr><tr><td>Total</td><td></td><td></td><td>$</td></tr></table>

(1) These amounts exclude contract carrier payments accounted for as operating leases of aircraft, which are described in Note 7.

Revenue Proration Agreement. As of December 31, 2017, a portion of our contract carrier agreement with SkyWest Airlines, Inc. is structured as a revenue proration agreement. This revenue proration agreement establishes a fixed dollar or percentage division of revenues for tickets sold to passengers traveling on connecting flight itineraries.

## Legal Contingencies

We are involved in various legal proceedings related to employment practices, environmental issues, antitrust matters and other matters concerning our business. We record liabilities for losses from legal proceedings when we determine that it is probable that the outcome in a legal proceeding will be unfavorable and the amount of loss can be reasonably estimated. Although the outcome of the legal proceedings in which we are involved cannot be predicted with certainty, we believe that the resolution of current matters will not have a material adverse effect on our Consolidated Financial Statements.

## Credit Card Processing Agreements

Our VISA/MasterCard and American Express credit card processing agreements provide that no cash reserve ("Reserve") is required, and no withholding of payment related to receivables collected will occur, except in certain circumstances, including when we do not maintain a required level of liquidity as outlined in the merchant processing agreements. In circumstances in which the credit card processor can establish a Reserve or withhold payments, the amount of the Reserve or payments that may be withheld would be equal to the potential liability of the credit card processor for tickets purchased with VISA/MasterCard or American Express credit cards, as applicable, that had not yet been used for travel. We did not have a Reserve or an amount withheld as of December 31, 2017 or 2016.



## Table of Contents

## Other Contingencies

## General Indemnifications

We are the lessee under many commercial real estate leases. It is common in these transactions for us, as the lessee, to agree to indemnify the lessor and the lessor's related parties for tort, environmental and other liabilities that arise out of or relate to our use or occupancy of the leased premises. This type of indemnity would typically make us responsible to indemnified parties for liabilities arising out of the conduct of, among others, contractors, licensees and invitees at, or in connection with, the use or occupancy of the leased premises. This indemnity often extends to related liabilities arising from the negligence of the indemnified parties, but usually excludes any liabilities caused by either their sole or gross negligence or their willful misconduct.

Our aircraft and other equipment lease and financing agreements typically contain provisions requiring us, as the lessee or obligor, to indemnify the other parties to those agreements, including certain of those parties' related persons, against virtually any liabilities that might arise from the use or operation of the aircraft or other equipment.

Certain of our aircraft and other financing transactions include provisions that require us to make payments to preserve an expected economic return to the lenders if that economic return is diminished due to certain changes in law or regulations. In certain of these financing transactions, we also bear the risk of certain changes in tax laws that would subject payments to non-U.S. lenders to withholding taxes.

We believe that our insurance would cover most of our exposure to liabilities and related indemnities associated with the commercial real estate leases and aircraft and other equipment lease and financing agreements described above. While our insurance does not typically cover environmental liabilities, we have certain insurance policies in place as required by applicable environmental laws.

We cannot reasonably estimate our potential future payments under the indemnities and related provisions described above because we cannot predict (1) when and under what circumstances these provisions may be triggered and (2) the amount that would be payable if the provisions were triggered because the amounts would be based on facts and circumstances existing at such time.

## Employees Under Collective Bargaining Agreements

At December 31, 2017, we had approximately 87,000 full-time equivalent employees. Approximately 19% of these employees were represented by unions. The following table shows our domestic airline employee groups that are represented by unions.

<table><tr><td>Employee Group</td><td>Approximate Number of Active Employees Represented</td><td>Union</td><td>Date on which Collective Bargaining Agreement Becomes Amendable</td></tr><tr><td>Delta Pilots</td><td>13,234</td><td>ALPA</td><td>December 31, 2019</td></tr><tr><td>Delta Flight Superintendents (Dispatchers)</td><td>420</td><td>PAFCA</td><td>March 31, 2018</td></tr><tr><td>Endeavor Air Pilots</td><td>1,805</td><td>ALPA</td><td>January 1, 2024</td></tr><tr><td>Endeavor Air Flight Attendants</td><td>1,160</td><td>AFA</td><td>December 31, 2018</td></tr><tr><td>Endeavor Air Dispatchers</td><td>55</td><td>PAFCA</td><td>December 31, 2018</td></tr></table>

In addition, 192 refinery employees of Monroe are represented by the United Steel Workers under an agreement that expires on February 28, 2019. This agreement is governed by the National Labor Relations Act, which generally allows either party to engage in self help upon the expiration of the agreement.

## Other

We have certain contracts for goods and services that require us to pay a penalty, acquire inventory specific to us or purchase contract-specific equipment, as defined by each respective contract, if we terminate the contract without cause prior to its expiration date. Because these obligations are contingent on our termination of the contract without cause prior to its expiration date, no obligation would exist unless such a termination occurs.



## NOTE 11 . INCOME TAXES

## Income Tax Provision

Our income tax provision consisted of the following:

<table><tr><td rowspan="2">(in millions)</td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2017</td><td>2016</td><td>2015</td><td></td></tr><tr><td>Current tax (provision) benefit:</td><td></td><td></td><td></td><td></td></tr><tr><td>Federal</td><td>$ (4)</td><td>$ —</td><td>$ (23)</td><td></td></tr><tr><td>State and local</td><td>5</td><td>(28)</td><td>(25)</td><td></td></tr><tr><td>International</td><td>(54)</td><td>(12)</td><td>(2)</td><td></td></tr><tr><td>Deferred tax provision:</td><td></td><td></td><td></td><td></td></tr><tr><td>Federal</td><td>(1,911)</td><td>(2,080)</td><td>(2,409)</td><td></td></tr><tr><td>State and local</td><td>(160)</td><td>(143)</td><td>(172)</td><td></td></tr><tr><td>Income tax provision</td><td>$ (2,124)</td><td>$ (2,263)</td><td>$ (2,631)</td><td></td></tr></table>

The following table presents the principal reasons for the difference between the effective tax rate and the U.S. federal statutory income tax rate:

<table><tr><td rowspan="2"></td><td colspan="3">Year Ended December 31,</td></tr><tr><td>2017</td><td>2016</td><td>2015</td></tr><tr><td>U.S. federal statutory income tax rate</td><td>35.0 %</td><td>35.0 %</td><td>35.0 %</td></tr><tr><td>State taxes, net of federal benefit</td><td>1.8</td><td>1.8</td><td>1.8</td></tr><tr><td>Decrease in valuation allowance</td><td>—</td><td>—</td><td>(0.2)</td></tr><tr><td>Foreign tax rate differential</td><td>(2.2)</td><td>(2.0)</td><td>—</td></tr><tr><td>Tax Cuts and Jobs Act adjustment</td><td>2.6</td><td>—</td><td>—</td></tr><tr><td>Other</td><td>—</td><td>(0.7)</td><td>0.2</td></tr><tr><td>Effective income tax rate</td><td>37.2 %</td><td>34.1 %</td><td>36.8 %</td></tr></table>

Following the enactment of the Tax Cuts and Jobs Act of 2017, we recorded a provisional tax expense estimate of $150 million resulting in a 2.6% increase in our effective tax rate. The provisional estimate includes recognition of tax expense related to certain of our undistributed foreign earnings and tax expense to decrease our federal net deferred tax asset to a 21% statutory tax rate. We are evaluating our share of undistributed earnings from certain of our foreign investments and will reflect the impact, if any, in 2018 when such impact is finalized.

As a result of the Tax Cuts and Jobs Act of 2017, we assessed tax on $732 million of foreign earnings which would have otherwise been indefinitely reinvested outside the U.S. At December 31, 2016, we had $379 million of undistributed foreign earnings.



## Table of Contents

## Deferred Taxes

Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes. The following table shows significant components of our deferred tax assets and liabilities:

<table><tr><td rowspan="2">(in millions)</td><td colspan="2">December 31,</td></tr><tr><td>2017</td><td>2016</td></tr><tr><td>Deferred tax assets:</td><td></td><td></td></tr><tr><td>Net operating loss carryforwards</td><td>$     1,440</td><td>$     2,485</td></tr><tr><td>Pension, postretirement and other benefits</td><td>2,545</td><td>5,259</td></tr><tr><td>Alternative minimum tax credit carryforward</td><td>379</td><td>379</td></tr><tr><td>Deferred revenue</td><td>1,024</td><td>1,544</td></tr><tr><td>Other</td><td>746</td><td>1,075</td></tr><tr><td>Valuation allowance</td><td>(19)</td><td>(40)</td></tr><tr><td>Total deferred tax assets</td><td>$     6,115</td><td>$     10,702</td></tr><tr><td>Deferred tax liabilities:</td><td></td><td></td></tr><tr><td>Depreciation</td><td>$     3,936</td><td>$     5,701</td></tr><tr><td>Intangible assets</td><td>1,070</td><td>1,691</td></tr><tr><td>Other</td><td>174</td><td>246</td></tr><tr><td>Total deferred tax liabilities</td><td>$     5,180</td><td>$     7,638</td></tr><tr><td>Net deferred tax assets</td><td>$     935</td><td>$     3,064</td></tr></table>

At December 31, 2017, we had $379 million of federal alternative minimum tax credit carryforwards. As a result of the Tax Cuts and Jobs Act of 2017, this credit becomes refundable to us if not used by 2021. We have $5.1 billion of federal pre-tax net operating loss carryforwards, which will not begin to expire until 2027.

## Income Tax Allocation

We consider all income sources, including other comprehensive income, in determining the amount of tax benefit allocated to continuing operations (the "Income Tax Allocation"). At the end of 2017, the Tax Cut and Jobs Act of 2017 reduced the statutory tax rate in the U.S. from 35% to 21% . GAAP requires that the tax expense related to tax law changes be recognized in current earnings, even when a portion of the related deferred tax asset originated through amounts recognized in AOCI. As a result, $700 million of income tax expense remains in AOCI, primarily related to pension obligations, and will not be recognized in net income until the pension obligations are fully extinguished, which will not occur for approximately 25 years.

## Other

The amount of, and changes to, our uncertain tax positions were not material in any of the years presented. We are currently under audit by the IRS for the 2017, 2016 and 2015 tax years.



## NOTE 12. EQUITY AND EQUITY COMPENSATION

## Equity

We are authorized to issue 2.0 billion shares of capital stock, of which up to 1.5 billion may be shares of common stock, par value $0.0001 per share, and up to 500 million may be shares of preferred stock.

Preferred Stock. We may issue preferred stock in one or more series. The Board of Directors is authorized (1) to fix the descriptions, powers (including voting powers), preferences, rights, qualifications, limitations and restrictions with respect to any series of preferred stock and (2) to specify the number of shares of any series of preferred stock. We have not issued any preferred stock.

Treasury Stock. We generally withhold shares of Delta common stock to cover employees' portion of required tax withholdings when employee equity awards are issued or vest. These shares are valued at cost, which equals the market price of the common stock on the date of issuance or vesting. The weighted average cost of shares held in treasury was $21.19 and $19.40 as of December 31, 2017 and 2016, respectively.

## Equity Compensation

Our broad-based equity and cash compensation plan provides for grants of restricted stock, stock options, performance awards, including cash incentive awards and other equity-based awards (the "Plan"). Shares of common stock issued under the Plan may be made available from authorized, but unissued, common stock or common stock we acquire. If any shares of our common stock are covered by an award that expires, is canceled, forfeited or otherwise terminates without delivery of shares (including shares surrendered or withheld for payment of taxes related to an award), such shares will again be available for issuance under the Plan except for (i) any shares tendered in payment of an option, (ii) shares withheld to satisfy any tax withholding obligation with respect to the exercise of an option or stock appreciation right ("SAR") or (iii) shares covered by a stock-settled SAR or other awards that were not issued upon the settlement of the award. The Plan authorizes the issuance of up to 163 million shares of common stock. As of December 31, 2017, there were 30 million shares available for future grants.

We make long-term incentive awards annually to eligible employees under the Plan. Generally, awards vest over time, subject to the employee's continued employment. Equity compensation expense for these awards is recognized in salaries and related costs over the employee's requisite service period (generally, the vesting period of the award) and totaled $108 million, $105 million and $76 million for the years ended December 31, 2017, 2016 and 2015, respectively. We record expense on a straight-line basis for awards with installment vesting. As of December 31, 2017, unrecognized costs related to unvested shares and stock options totaled $82 million. We expect substantially all unvested awards to vest and recognize any forfeitures as they occur.

Restricted Stock. Restricted stock is common stock that may not be sold or otherwise transferred for a period of time and is subject to forfeiture in certain circumstances. The fair value of restricted stock awards is based on the closing price of the common stock on the grant date. As of December 31, 2017, there were 2.6 million unvested restricted stock awards.

Stock Options. Stock options are granted with an exercise price equal to the closing price of Delta common stock on the grant date and generally have a 10-year term. We determine the fair value of stock options at the grant date using an option pricing model. As of December 31, 2017, there were 1.9 million outstanding stock option awards with a weighted average exercise price of $38.59, and 771 thousand were exercisable.

Performance Awards. Performance awards are long-term incentive opportunities, which are payable in common stock and/or cash, and are generally contingent upon our achieving certain financial goals.

Other. During 2017 and 2016, we recognized $21 million and $33 million, respectively, of excess tax benefits in our income tax provision.

(1) Amounts reclassified from AOCI for pension and other benefits liabilities and for derivative contracts designated as foreign currency cash flow hedges are recorded in salaries and related costs and in passenger revenue, respectively, in the Consolidated Statements of Operations. The reclassification into earnings for investments relates to our investment in Grupo Aeromexico and the related conversion to accounting under the equity method. The reclassification of the unrealized gain was recorded to non-operating expense in our Consolidates Statements of Operations.

(2) Includes $700 million of deferred income tax expense, primarily related to pension obligations, that will not be recognized in net income until the pension obligations are fully extinguished. We consider all income sources, including other comprehensive income, in determining the amount of tax benefit allocated to continuing operations.

## NOTE 14 . SEGMENTS AND GEOGRAPHIC INFORMATION

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker and is used in resource allocation and performance assessments. Our chief operating decision maker is considered to be our executive leadership team. Our executive leadership team regularly reviews discrete information for our two operating segments, which are determined by the products and services provided: our airline segment and our refinery segment.

## Airline Segment

Our airline segment is managed as a single business unit that provides scheduled air transportation for passengers and cargo throughout the U.S. and around the world and other ancillary airline services. This allows us to benefit from an integrated revenue pricing and route network. Our flight equipment forms one fleet, which is deployed through a single route scheduling system. When making resource allocation decisions, our chief operating decision maker evaluates flight profitability data, which considers aircraft type and route economics, but gives no weight to the financial impact of the resource allocation decision on an individual carrier basis. Our objective in making resource allocation decisions is to optimize our consolidated financial results.

## Refinery Segment

In June 2012, our wholly owned subsidiaries, Monroe Energy, LLC, and MIPC, LLC (collectively, "Monroe"), acquired the Trainer oil refinery and related assets located near Philadelphia, Pennsylvania, as part of our strategy to mitigate the cost of the refining margin reflected in the price of jet fuel. The acquisition included pipelines and terminal assets that allow the refinery to supply jet fuel to our airline operations throughout the Northeastern U.S., including our New York hubs at LaGuardia and JFK. We accounted for the refinery acquisition as a business combination.

Our refinery segment operates for the benefit of the airline segment by providing jet fuel to the airline segment from its own production and through jet fuel obtained through agreements with third parties. The refinery's production consists of jet fuel as well as non-jet fuel products. We use several counterparties to exchange the non-jet fuel products produced by the refinery for jet fuel consumed in our airline operations. The gross fair value of the products exchanged under these agreements during the years ended December 31, 2017, 2016 and 2015 was $3.2 billion, $2.7 billion and $3.1 billion, respectively.



## Segment Reporting

Segment results are prepared based on our internal accounting methods described below, with reconciliations to consolidated amounts in accordance with GAAP. Our segments are not designed to measure operating income or loss directly related to the products and services included in each segment on a stand-alone basis.

<table><tr><td>(in millions)</td><td>Airline</td><td>Refinery</td><td>Intersegment Sales/Other</td><td>Consolidated</td></tr><tr><td>Year Ended December 31, 2017</td><td></td><td></td><td></td><td></td></tr><tr><td>Operating revenue:</td><td>$ 40,742</td><td>$ 5,039</td><td></td><td>$ 41,244</td></tr><tr><td>Sales to airline segment</td><td></td><td></td><td>$ (886) (1)</td><td></td></tr><tr><td>Exchanged products</td><td></td><td></td><td>(3,240) (2)</td><td></td></tr><tr><td>Sales of refined products</td><td></td><td></td><td>(411) (3)</td><td></td></tr><tr><td>Operating income</td><td>6,004</td><td>110</td><td></td><td>6,114</td></tr><tr><td>Interest expense (income), net</td><td>403</td><td>(7)</td><td></td><td>396</td></tr><tr><td>Depreciation and amortization</td><td>2,188</td><td>47</td><td></td><td>2,235</td></tr><tr><td>Total assets, end of period</td><td>51,165</td><td>2,127</td><td></td><td>53,292</td></tr><tr><td>Capital expenditures</td><td>3,743</td><td>148</td><td></td><td>3,891</td></tr><tr><td>Year Ended December 31, 2016</td><td></td><td></td><td></td><td></td></tr><tr><td>Operating revenue:</td><td>$ 39,406</td><td>$ 3,843</td><td></td><td>$ 39,639</td></tr><tr><td>Sales to airline segment</td><td></td><td></td><td>$ (695) (1)</td><td></td></tr><tr><td>Exchanged products</td><td></td><td></td><td>(2,658) (2)</td><td></td></tr><tr><td>Sales of refined products</td><td></td><td></td><td>(257) (3)</td><td></td></tr><tr><td>Operating income (loss) (4)</td><td>7,077</td><td>(125)</td><td></td><td>6,952</td></tr><tr><td>Interest expense, net</td><td>386</td><td>2</td><td></td><td>388</td></tr><tr><td>Depreciation and amortization</td><td>1,862</td><td>40</td><td></td><td>1,902</td></tr><tr><td>Total assets, end of period</td><td>49,930</td><td>1,331</td><td></td><td>51,261</td></tr><tr><td>Capital expenditures</td><td>3,270</td><td>121</td><td></td><td>3,391</td></tr><tr><td>Year Ended December 31, 2015</td><td></td><td></td><td></td><td></td></tr><tr><td>Operating revenue:</td><td>$ 40,398</td><td>$ 4,741</td><td></td><td>$ 40,704</td></tr><tr><td>Sales to airline segment</td><td></td><td></td><td>$ (990) (1)</td><td></td></tr><tr><td>Exchanged products</td><td></td><td></td><td>(3,108) (2)</td><td></td></tr><tr><td>Sales of refined products</td><td></td><td></td><td>(337) (3)</td><td></td></tr><tr><td>Operating income (4)</td><td>7,512</td><td>290</td><td></td><td>7,802</td></tr><tr><td>Interest expense, net</td><td>481</td><td>—</td><td></td><td>481</td></tr><tr><td>Depreciation and amortization</td><td>1,805</td><td>30</td><td></td><td>1,835</td></tr><tr><td>Total assets, end of period</td><td>51,785</td><td>1,349</td><td></td><td>53,134</td></tr><tr><td>Capital expenditures</td><td>2,853</td><td>92</td><td></td><td>2,945</td></tr></table>

(1) Represents transfers, valued on a market price basis, from the refinery to the airline segment for use in airline operations. We determine market price by reference to the market index for the primary delivery location, which is New York Harbor, for jet fuel from the refinery.

(2) Represents value of products delivered under our exchange agreements, as discussed above, determined on a market price basis.

(3) These sales were at or near cost; accordingly, the margin on these sales is de minimis.

## Table of Contents

## Geographic Information

Operating revenue for the airline segment is recognized in a specific geographic region based on the origin, flight path and destination of each flight segment. The majority of the revenues of the refinery, consisting of fuel sales to the airline, have been eliminated in the Consolidated Financial Statements. The remaining operating revenue for the refinery segment is included in the domestic region.

Our operating revenue by geographic region (as defined by the U.S. Department of Transportation) is summarized in the following table:

<table><tr><td rowspan="2">(in millions)</td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2017</td><td>2016</td><td>2015</td><td></td></tr><tr><td>Domestic</td><td>$ 29,556</td><td>$ 28,108</td><td>$ 27,884</td><td></td></tr><tr><td>Atlantic</td><td>6,044</td><td>5,919</td><td>6,505</td><td></td></tr><tr><td>Pacific</td><td>2,730</td><td>2,939</td><td>3,503</td><td></td></tr><tr><td>Latin America</td><td>2,914</td><td>2,673</td><td>2,812</td><td></td></tr><tr><td>Total</td><td>$ 41,244</td><td>$ 39,639</td><td>$ 40,704</td><td></td></tr></table>

Our tangible assets consist primarily of flight equipment, which is mobile across geographic markets. Accordingly, assets are not allocated to specific geographic regions.

## NOTE 15. RESTRUCTURING

The following table shows the balances and activity for restructuring charges:

<table><tr><td>(in millions)</td><td>2017</td><td>2016</td><td>2015</td></tr><tr><td>Liability at beginning of period</td><td>$ 333</td><td>$ 467</td><td>$ 504</td></tr><tr><td>Payments</td><td>(103)</td><td>(144)</td><td>(127)</td></tr><tr><td>Additional expenses and other</td><td>7</td><td>10</td><td>90</td></tr><tr><td>Liability at end of period</td><td>$ 237</td><td>$ 333</td><td>$ 467</td></tr></table>

Restructuring charges primarily include remaining lease payments for permanently grounded aircraft related to domestic and Pacific fleet restructurings. We are continuing to restructure our domestic fleet by replacing a portion of our 50-seat regional fleet with more efficient and customer preferred aircraft and replacing older, less cost effective B-757-200 aircraft with B-737-900ER aircraft. We are also restructuring our Pacific network by retiring the B-747-400 fleet (the last aircraft retired during 2017) and replacing the fleet with smaller-gauge, widebody aircraft to better match capacity with demand.



## NOTE 16. EARNINGS PER SHARE

We calculate basic earnings per share by dividing the net income by the weighted average number of common shares outstanding, excluding restricted shares. We calculate diluted earnings per share by dividing net income by the weighted average number of common shares outstanding plus the dilutive effect of outstanding share-based awards, including stock options and restricted stock awards. Antidilutive common stock equivalents excluded from the diluted earnings per share calculation are not material. The following table shows our computation of basic and diluted earnings per share:

<table><tr><td rowspan="2">(in millions, except per share data)</td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2017</td><td>2016</td><td>2015</td><td></td></tr><tr><td>Net income</td><td>$ 3,577</td><td>$ 4,373</td><td>$ 4,526</td><td></td></tr><tr><td>Basic weighted average shares outstanding</td><td>720</td><td>751</td><td>797</td><td></td></tr><tr><td>Dilutive effect of share-based awards</td><td>3</td><td>4</td><td>7</td><td></td></tr><tr><td>Diluted weighted average shares outstanding</td><td>723</td><td>755</td><td>804</td><td></td></tr><tr><td>Basic earnings per share</td><td>$ 4.97</td><td>$ 5.82</td><td>$ 5.68</td><td></td></tr><tr><td>Diluted earnings per share</td><td>$ 4.95</td><td>$ 5.79</td><td>$ 5.63</td><td></td></tr></table>

## NOTE 17. QUARTERLY FINANCIAL DATA (UNAUDITED)

The following table summarizes our unaudited results of operations on a quarterly basis. The quarterly earnings per share amounts for a year will not add to the earnings per share for that year due to the weighting of shares used in calculating per share data.

## ITEM 9A. CONTROLS AND PROCEDURES

## Disclosure Controls and Procedures

Our management, including our Chief Executive Officer and Chief Financial Officer, performed an evaluation of our disclosure controls and procedures, which have been designed to permit us to record, process, summarize and report, within time periods specified by the SEC's rules and forms, information required to be disclosed. Our management, including our Chief Executive Officer and Chief Financial Officer, concluded that the controls and procedures were effective as of December 31, 2017 to ensure that material information was accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

## Changes in Internal Control

During the three months ended December 31, 2017, we did not make any changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

## Management's Annual Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. Our internal control over financial reporting is 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 of America.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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 may deteriorate.

Management conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2017 using the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in the 2013 Internal Control-Integrated Framework. Based on that evaluation, management believes that our internal control over financial reporting was effective as of December 31, 2017.

The effectiveness of our internal control over financial reporting as of December 31, 2017 has been audited by Ernst & Young LLP, an independent registered public accounting firm, which also audited our Consolidated Financial Statements for the year ended December 31, 2017. Ernst & Young LLP's report on our internal control over financial reporting is set forth below.



## REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of Delta Air Lines, Inc.

## Opinion on Internal Control over Financial Reporting

We have audited Delta Air Lines, Inc.'s internal control over financial reporting as of December 31, 2017, 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, Delta Air Lines, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, 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, 2017 and 2016, and the related consolidated statements of operations, comprehensive income, cash flows and stockholders' equity for each of the three years in the period ended December 31, 2017, and the related notes and our report dated February 23, 2018 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 Limitation 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.

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.

## 2.1 Aircraft Specification

2.1.1 The Aircraft shall be manufactured in accordance with the Standard Specification, as may already have been modified or varied prior to the date of the Agreement by the Specification Change Notices listed in Exhibits A-3 or A-4, as applicable.

## 2.2 Specification Amendment

The parties understand and agree that the Specification may be further amended following signature of this Agreement in accordance with the terms of this Clause 2.

## 2.2.1 Specification Change Notice

The Specification may be amended by written agreement between the parties in a Specification Change Notice (“SCN”). Each SCN will be substantially in the form set out in Exhibit B-1 and will set out the SCN’s Aircraft embodiment rank and will also set forth, in detail, the particular change to be made to the Specification and the effect, if any, of such change on design, performance, weight, Delivery Date of the Aircraft affected thereby and on the text of the Specification. An SCN may result in an adjustment of the Base Price of the Aircraft, which adjustment, if any, will be specified in the SCN.

## 2.2.2 Development Changes

The Specification may also be amended to incorporate changes deemed necessary by the Seller to improve the Aircraft, prevent delay or ensure compliance with this Agreement (“Development Changes”), as set forth in this Clause 2.

## 2.2.2.1 Manufacturer Specification Changes Notices

The Specification may be amended by the Seller through a Manufacturer Specification Change Notice (“MSCN”), which will be substantially in the form set out in Exhibit B-2 hereto and will set out the MSCN’s Aircraft embodiment rank as well as, in detail, the particular change to be made to the Specification and the effect, if any, of such change on performance, weight, Base Price of the Aircraft, Delivery Date of the Aircraft affected thereby and interchangeability or replaceability requirements under the Specification.

Except when the MSCN is necessitated by an Aviation Authority directive or by equipment obsolescence, in which case the MSCN will be accomplished without requiring the Buyer’s consent, if the MSCN adversely affects the performance, weight, Base Price, Delivery Date of the Aircraft affected thereby or the interchangeability or replaceability requirements under the Specification, the Seller will notify the Buyer of a reasonable period of time during which the Buyer must accept or reject such MSCN. If the Buyer does not notify the Seller



of the rejection of the MSCN within such period, the MSCN will be deemed accepted by the Buyer and the corresponding modification will be accomplished.

2.2.2.2 In the event of the Seller revising the Specification to incorporate Development Changes which have no adverse effect on any of the elements as set forth in Subclause 2.2.2.1 above, such revision will be performed by the Seller without the Buyer's consent.

In such cases, the Buyer will have access to the details of such changes through the relevant application in AirbusWorld.

2.2.2.3 The Seller is considering turning certain items, which are currently BFE in the Specification, into SFE and the parties agree that such BFE items shall be excluded from the provisions of Subclauses 2.2.2.1 and 2.2.2.2 above and, should they become SFE, shall furthermore be chargeable to the Buyer.

The A321 NEO Aircraft shall be equipped with a set of either two (2) CFM LEAP-1A32 engines or two (2) International Aero Engines, LLC (“IAE LLC”) PW1133G-JM engines, upon selection referred to respectively as the “A321 NEO Propulsion Systems”.

If the Buyer has not selected the A321 NEO Propulsion Systems as of the date of this Agreement, such choice shall be made no later than sixty (60) days after such date by the execution of an SCN.

## 2.4 Milestones

## 2.4.1 Customization Milestones Chart

Buyer reasonably believes to be attributable to the design characteristics of one or more components of the Aircraft (an “Interface Problem”), the Seller shall, if requested by the Buyer, and without additional charge to the Buyer, except for transportation of the Seller’s personnel to the Buyer’s facilities, promptly conduct or have conducted an investigation and analysis of such problem to determine, if possible, the cause or causes of the problem and to recommend such corrective action as may be feasible, provided, however, that if the Seller determines, after such due and reasonable investigation, that the Interface Problem was due to or caused by any default by the Buyer in performance of its obligations hereunder, the Buyer shall pay to the Seller all reasonable costs and expenses incurred by the Seller during such investigation. The Buyer shall furnish to the Seller all data and information in the Buyer’s possession relevant to the Interface Problem and shall cooperate with the Seller in the conduct of the Seller’s investigations and such tests as may be required.

## 12.4.4 Joint Responsibility

If the Seller determines that the Interface Problem is attributable partially to the design of a Warranted Part and partially to the design of any Supplier Component, the Seller shall, if requested by the Buyer, seek a solution to the Interface Problem through cooperative efforts of the Seller and any Supplier involved. The Seller shall promptly advise the Buyer of such corrective action as may be proposed by the Seller and any such Supplier. Such proposal shall be consistent with any then existing obligations of the Seller hereunder and of any such Supplier to the Buyer. Such corrective action, when reasonably accepted by the Buyer, shall constitute full satisfaction of any claim the Buyer may have against either the Seller or any such Supplier with respect to such Interface Problem.

## 2.2 Specification Amendment

The parties understand and agree that the Specification may be further amended following signature of the Agreement in accordance with the terms of this Subclause 2.2.

## 2.2.1 Specification Change Notice

The Specification may be amended by written agreement between the parties substantially in the form set out in Exhibit B-1 (each, a “Specification Change Notice” or “SCN”). Each SCN shall set forth the particular Aircraft that would be affected by the SCN as well as, in detail, the particular changes to be made in the Specification, any materials to be deleted from the Aircraft by the Seller in connection with such SCN, and the effect, if any, of such changes on design, performance, weight, balance, Scheduled Delivery Month, Buyer Furnished Equipment and price of each Aircraft affected thereby and interchangeability or replaceability of parts.

## 2.2.2 Requests and Approvals

2.2.2.1 [***] If the Seller determines [***], the Seller shall (i) inform the Buyer of the technical results and (ii) provide the Buyer with an estimated commercial offer as well as the date by which acceptance of such offer shall be required. Following the Buyer’s acceptance of the technical and commercial offer, the Seller will produce an [***]. If such [***] by the Buyer, [***] shall be cancelled without charge to the Buyer.

2.2.2.2 In the event that the Buyer requests the Seller in writing to incorporate a proposed change (excluding Development Changes) in an Aircraft and the Seller agrees to such request but the change is not subsequently made the subject of an SCN for any reason (other than the Seller’s unreasonable refusal to sign the SCN or otherwise acting in bad faith), [***] and incurred by the Seller, provided that in the event the Seller’s reasonable estimate of the cost of developing such proposed change [***] after the Seller’s receipt of the Buyer’s request to incorporate a proposed change and secured the Buyer’s agreement prior to incurring any such costs.

## 2.2.3 Development Changes

The Specification may also be amended to incorporate changes deemed necessary by the Seller to improve the Aircraft, prevent delay or ensure compliance with the Agreement (“Development Changes”), as set forth in this Subclause 2.2.3.



## 2.2.3.1 Manufacturer Specification Change Notices

The Specification may be amended by the Seller through a Manufacturer Specification Change Notice (“MSCN”), which shall be substantially in the form set out in Exhibit B-2 hereto, or by such other means as may be deemed appropriate, and shall set forth the particular Aircraft that are affected by the MSCN as well as, in detail, the particular changes to be made in the Specification, any materials to be deleted from the Aircraft by the Seller in connection with such SCN, and the effect, if any, of such changes on design, performance, weight, balance, Scheduled Delivery Month, Buyer Furnished Equipment and price of each Aircraft affected thereby and interchangeability or replaceability of parts.

Except when the MSCN is necessitated by an Aviation Authority directive or by equipment obsolescence, in which case the MSCN shall be accomplished without requiring the Buyer’s consent, if the MSCN adversely affects the performance, weight, Base Price, Delivery Date of the Aircraft affected thereby or the interchangeability or replaceability requirements under the Specification, the Seller shall notify the Buyer of a reasonable period of time during which the Buyer must accept or reject such MSCN. If the Buyer does not notify the Seller of the rejection of the MSCN within such period, the MSCN shall be deemed accepted by the Buyer and the corresponding modification shall be accomplished; provided however, if the Buyer rejects an MSCN, neither the Specification nor the Base Price of the Aircraft shall change.

For the purposes of Subclause 2.2.3.1, the term “equipment obsolescence” refers to equipment which is no longer manufactured or available commercially.

2.2.3.2 In the event of the Seller revising the Specification to incorporate Development Changes which have no adverse effect on the performance, weight, Base Price, Delivery Date of the Aircraft affected thereby or the interchangeability or replaceability requirements under the Specification, such revision shall be performed by the Seller without the Buyer’s consent. In such cases, the Buyer shall have access to the details of such changes through the relevant application in AirbusWorld.

2.2.3.3 The Seller is considering turning certain items, which are currently BFE in the Specification, into Seller Furnished Equipment. If such BFE becomes Seller Furnished Equipment, it shall be excluded from the provisions of Subclauses 2.2.3.1 and 2.2.3.2 above and be chargeable to the Buyer, however, the price of such Seller Furnished Equipment shall not exceed the price of such BFE.

## First Amendment to
The Delta Air Lines, Inc. 2015 Long-Term Incentive Program

Section 2 of the Delta Air Lines, Inc. 2015 Long-Term Incentive Program is amended by adding the following new subsection (d) to the end thereof:

“(d) Notwithstanding any provision of the 2015 LTIP or the Performance Compensation Plan to the contrary, the minimum amount of total Performance Awards payable to eligible Participants (the “Minimum Amount”) may be fixed by the Committee (or its delegate) on or prior to the end of the Performance Period, but in no event earlier than one calendar month prior to the end of the Performance Period. Once so determined by the Committee (or its delegate), the Minimum Amount shall not be further reduced or eliminated at any time thereafter. Any portion of the Minimum Amount allocated to such Participants that may be forfeited pursuant to the terms of the 2015 LTIP shall be reallocated among the other eligible Participants.”



# DELTA AIR LINES, INC.
2017 LONG-TERM INCENTIVE PROGRAM

1. Purpose. The 2017 Long-Term Incentive Program (the “2017 LTIP”) is a long term incentive program sponsored by Delta Air Lines, Inc. (“Delta” or the “Company”) that is intended to closely: (a) link pay and performance by providing management employees with a compensation opportunity based on Delta achieving key business objectives and (b) align the interests of management employees with the Company’s other employees and stakeholders.

The 2017 LTIP is being adopted under the Delta Air Lines, Inc. Performance Compensation Plan (“Performance Compensation Plan”). It is subject to the terms of the Performance Compensation Plan and an individual’s 2017 LTIP Award Agreement (“Award Agreement”).

Capitalized terms that are used but not defined in the 2017 LTIP shall have the meaning ascribed to them in the Performance Compensation Plan.

2. Plan Administration . (a) The Personnel & Compensation Committee of the Board of Directors (the “Committee”) shall be responsible for the general administration and interpretation of the 2017 LTIP and for carrying out its provisions. The Committee shall have such powers as may be necessary to discharge its duties hereunder, including, without limitation, the following powers and duties, but subject to the terms of the 2017 LTIP:

(i) authority to construe and interpret the terms of the 2017 LTIP and to determine eligibility, awards and the amount, manner and time of payment of any awards hereunder;

(ii) authority to prescribe forms and procedures for purposes of the 2017 LTIP participation and distribution of awards; and

(iii) authority to adopt rules and regulations and to take such actions as it deems necessary or desirable for the proper administration of the 2017 LTIP, which authority may be delegated to the Company’s Chief Human Resources Officer.

(b) Any rule or decision by the Committee that is not inconsistent with the provisions of the 2017 LTIP shall be conclusive and binding on all persons and shall be given the maximum deference permitted by law.

(c) Notwithstanding anything contained in the Performance Compensation Plan to the contrary, the Committee shall not have the authority to increase or decrease the actual payout of any Performance Award (as defined below) granted to any Participant pursuant to Section 4(b).

3. Individual Award Agreements. Any person offered an Award under the 2017 LTIP will be required to sign an individual Award Agreement. Execution by such person of his or her Award Agreement will be a prerequisite to the effectiveness of the Award under the 2017 LTIP and to the person becoming a Participant in the 2017 LTIP. The terms and conditions of any Award Agreement, if contrary to the terms of the 2017 LTIP, shall govern the rights of the corresponding Participant.



## 4. Awards.

## (a) Restricted Stock.

(i) Award Grant. A Participant may receive Restricted Stock as specified in the Participant’s Award Agreement (the “Restricted Stock”).

(ii) Grant Date. The Grant Date of the Restricted Stock will be determined by the Committee in accordance with the Company’s Equity Award Grant Policy, as in effect from time to time, and set forth in a Participant’s Award Agreement.

(iii) Restrictions. Until the restrictions imposed by this Section 4(a) (the “Restrictions”) have lapsed pursuant to Section 4(a)(iv), (v) or (vi), a Participant will not be permitted to sell, exchange, assign, transfer or otherwise dispose of the Restricted Stock and the Restricted Stock will be subject to forfeiture as set forth below.

(iv) Lapse of Restrictions—Continued Employment. Subject to the terms of the Performance Compensation Plan and the 2017 LTIP, the Restrictions shall lapse and be of no further force or effect with respect to one-third of the Shares of Restricted Stock on each of the following dates: (A) February 1, 2018 (“First RS Installment”); (B) February 1, 2019 (“Second RS Installment”); and (C) February 1, 2020 (“Third RS Installment”). \( ^{1} \) 

(v) Lapse of Restrictions/Forfeiture upon Termination of Employment. The Restricted Stock and the Restrictions set forth in this Section 4(a) are subject to the following terms and conditions:

(A) Without Cause or For Good Reason. Upon a Participant’s Termination of Employment by the Company without Cause or by the Participant for Good Reason (including the Termination of Employment of the Participant if he or she is employed by an Affiliate at the time the Company sells or otherwise divests itself of such Affiliate), with respect to any portion of the Restricted Stock subject to the Restrictions, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, the Restrictions shall immediately lapse on the Pro Rata RS Portion as of the date of such Termination of Employment. Upon a Participant’s Termination of Employment by the Company without Cause or by the Participant for Good Reason, any Restricted Stock that remains subject to the Restrictions, other than the Pro Rata RS Portion, shall be immediately forfeited.

“Pro Rata RS Portion” means, with respect to any portion of Restricted Stock that is subject to the Restrictions at the time of a Participant’s Termination of Employment, the number of Shares with respect to which the Restrictions would have lapsed on each future RS Installment multiplied by a fraction (i) the numerator of which is the number of calendar months \( ^{2} \)  from the Grant Date to the date of such Termination of Employment, rounded up for any partial month and (ii) the denominator of which is twelve (12) for the First RS Installment, twenty-four (24) for the Second RS Installment and thirty-six (36) for the Third RS Installment. \( ^{3} \)



(B) Voluntary Resignation. Upon a Participant’s Termination of Employment by reason of a voluntary resignation (other than for Good Reason or Retirement), any portion of the Restricted Stock subject to the Restrictions shall be immediately forfeited.

(C) Retirement. Subject to Section 4(a)(v)(F), upon a Participant’s Termination of Employment by reason of Retirement, with respect to any portion of the Restricted Stock subject to the Restrictions, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, the Restrictions shall immediately lapse on the Pro Rata RS Portion as of the date of such Termination of Employment. Pro Rata RS Portion has the meaning set forth in Section 4(a)(v)(A). Upon a Participant’s Termination of Employment by reason of Retirement, any Restricted Stock that remains subject to the Restrictions, other than the Pro Rata RS Portion, shall be immediately forfeited.

(D) Death or Disability. Upon a Participant’s Termination of Employment due to death or Disability, the Restrictions shall immediately lapse and be of no further force or effect as of the date of such Termination of Employment.

(F) Retirement-Eligible Participants Who Incur a Termination of Employment for Other Reasons. If a Participant who is eligible for Retirement is or would be terminated by the Company without Cause, such Participant shall be considered to have been terminated by the Company without Cause for purposes of the 2017 LTIP rather than having retired, but only if the Participant acknowledges that, absent Retirement, the Participant would have been terminated by the Company without Cause. If, however, the employment of a Participant who is eligible for Retirement is terminated by the Company for Cause, then, regardless of whether the Participant is considered as a retiree for purposes of any other program, plan or policy of the Company, for purposes of the 2017 LTIP, the Participant’s employment shall be considered to have been terminated by the Company for Cause.

(vi) Change in Control. Notwithstanding the foregoing and subject to Section 5, upon a Participant’s Termination of Employment by the Company without Cause or by the Participant for Good Reason (including the Termination of Employment of the Participant if he or she is employed by an Affiliate at the time the Company sells or otherwise divests itself of such Affiliate) on or after a Change in Control but prior to the second anniversary of such Change in Control, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, any Restrictions in effect shall immediately lapse on the date of such Termination of Employment and be of no further force or effect as of such date.

(iii) Payout Criteria and Form of Payment. Except as otherwise expressly set forth in this Section 4(b), payment, if any, of a Performance Award will be based on the following factors as described and defined below: (A) the Total Revenue per Available Seat Mile (“TRASM”) Performance during the Performance Period of the Company as compared to the Industry Group members; (B) Customer Service Performance during the Performance Period of the Company; (C) Return on Invested Capital during the Performance Period of the Company; and (D) the Relative Total Shareholder Return (“TSR”) Performance during the Performance Period of the Company as compared to the S&P 500 Companies.

(iv) Definitions.

(A) In General.

(1) The “Conversion Formula” will apply to convert from cash to Shares the payout, if any, of a Performance Award to a person who is an Executive Officer Participant at the time of such payout.

Next, the cash amount is converted into a number of Shares based on the following formula:  \( (A \div B) \) , where:

A = the amount of the payout for the Performance Award if it is paid in cash; and

B = the closing price of a Share on the New York Stock Exchange on the later of (1) the date that the Committee approves the payouts, if any, of the Performance Awards to the Executive Officer Participants following the Committee’s determination of the achievement of the payout criteria described in Section 4(b) (iii) and (2) the third business day following the date on which the Company publicly announces its annual financial results if this date is scheduled in the same month that the Committee approves such payouts, if any.

(2) “GAAP” means accounting principles generally accepted in the United States of America.

B = Available Seat Miles for 2017, 2018 and 2019.

(3) The “Industry Group Average TRASM” shall be calculated by using the aggregate Available Seat Miles and aggregate Total Operating Revenue for the applicable periods and the following formula: (A÷B), where

A = Total Operating Revenue for 2017, 2018 and 2019 for each of the members of the Industry Group; and

B = Available Seat Miles for 2017, 2018 and 2019 for each member of the Industry Group.

The criteria and methodology used to determine Delta’s NPS is described in a document titled, “‘Net Promoter’: Measuring Customer Satisfaction at Delta,” which was previously reviewed by the Committee. Company management will periodically report to the Company’s Board of Directors regarding Delta’s NPS.

(D) Return on Invested Capital.

(1)The “Return on Invested Capital” for Delta shall be calculated by using Delta’s Average Adjusted Total Net Operating Income and Average Invested Capital for the applicable periods and the following formula (A÷B), where:

A = Average Adjusted Total Net Operating Income for 2017, 2018 and 2019; and



(2)“ Average Adjusted Total Net Operating Income ” means, subject to Section 4(b)(v)(B), (i) Delta’s average consolidated operating income for the applicable periods based on its regularly prepared and publicly available statements of operations prepared in accordance with GAAP, but excluding (A) items present in the line item “restructuring and other items” or such similar line item; (B) mark-to-market adjustments for hedges recorded in periods other than the settlement period; (C) other special, unusual or nonrecurring items which are disclosed in publicly available filings with the U.S. Securities and Exchange Commission (the “SEC”); and (D) implied interest in aircraft rent expense and amortized pension expense related to gains/losses that impact accumulated other comprehensive income (“AOCI”) multiplied by (ii) one minus Delta’s Effective Tax Rate for the applicable periods.

(2)“TSR Percentile Ranking” means the percentage of the S&P 500 Companies with Total Shareholder Return for the Performance Period that is less than or equal to Delta’s Total Shareholder Return. If the Company’s Total Shareholder Return is the same as another company’s Total Shareholder Return, the Company shall be treated as having the higher Total Shareholder Return. The percentile ranking shall be carried out to two decimal places.

(3)“S&P 500 Companies” means all of the companies constituting the Standard & Poor’s 500 Index as of the first and last day of the Performance Period (excluding the Company) and which continue to be actively traded under the same ticker symbol on an established securities market through the end of the Performance Period.

## (v) Vesting.

(A) General. Subject to the terms of the Performance Compensation Plan, the 2017 LTIP and all other conditions included in any applicable Award Agreement, the Performance Award shall vest, as described in this Section 4(b)(v), as of the end of the Performance Period



to the extent that the Company’s actual performance results meet or exceed Threshold level with respect to TRASM Performance, Customer Service Performance, Return on Invested Capital and/or Relative TSR Performance, as applicable and as described below. For purposes of TRASM Performance, the Company’s performance is compared against the Industry Group Average TRASM. For purposes of Relative TSR Performance, the Company’s performance is compared against the S&P 500 Companies.

(B) Committee’s Authority. In determining the TRASM for Delta and each member of the Industry Group and the Return on Invested Capital for Delta, the Committee shall make such adjustments with respect to any subject company as is necessary to ensure the results are comparable, including, without limitation, differences or changes in accounting policies, standards, practices, guidelines, reclassifications or restatements (for example, fuel hedging, purchase accounting adjustments associated with mergers, acquisitions or divestitures, or fresh start accounting as a result of emergence from bankruptcy). Without limiting the generality of the foregoing, the Committee shall (i) make such determinations based on financial data filed by the subject company with the SEC or otherwise and (ii) exclude from any calculation any item of gain, loss or expense determined to be special or unusual in nature or infrequent in occurrence.

(C) Impact of Certain Events. A company shall be automatically removed from the Industry Group in the event that any of the following occur during or with respect to the Performance Period: (i) such company ceases to maintain or does not timely prepare publicly available statements of operations prepared in accordance with GAAP; (ii) such company is not the surviving entity in any merger, consolidation or other non-bankruptcy reorganization (or survives only as a subsidiary of an entity other than a previously wholly owned subsidiary of such company); (iii) such company sells, leases or exchanges all or substantially all of its assets to any other person or entity (other than a previously wholly owned subsidiary of such company); (iv) such company is dissolved and liquidated; or (v) more than 20% of such company's revenues (determined on a consolidated basis based on the regularly prepared and publicly available statements of operations of such company prepared in accordance with GAAP) for any fiscal year of such company are attributable to the operation of businesses other than such company's airline business and such company does not provide publicly available statements of operations with respect to its airline business that are separate from the statements of operations provided with respect to its other businesses.

(D) Transactions Between Airlines. To the extent reasonably practicable, in the event of a merger, consolidation or similar transaction during the Performance Period between Delta and any other airline, including a member of the Industry Group, or between any member of the Industry Group and any other airline, including another member of the Industry Group (an “Airline Merger”), TRASM for any such company involved in an Airline Merger will be calculated on a combined basis as if the Airline Merger had occurred on January 1, 2017, removing the effects of purchase accounting-related adjustments. Furthermore, to the extent reasonably practicable, in the event of an acquisition or divestiture or similar transaction during the Performance Period between Delta and any regional carrier or between any member of the Industry Group and any regional carrier (a “Regional Carrier Transaction”), TRASM and, as applicable, Return on Invested Capital for any such company involved in a Regional Carrier Transaction will be calculated to remove the impact of any reclassifications of costs from (or to) such company’s presentation of contract carrier expense to (or from) the other expense line items on the statement of operations (determined based on the regularly prepared and publicly available statements of operations of such company prepared in accordance with GAAP).



(E) Vesting/Performance Measures. The payment, if any, a Participant will receive in connection with the vesting of the Performance Award will be based on the following:

<table><tr><td rowspan="2"></td><td colspan="3">Performance Measure</td><td>Weighting</td></tr><tr><td>Threshold (50% of Target)</td><td>Target (100% of Target)</td><td>Maximum (200% of Target)</td><td></td></tr><tr><td>TRASM Performance</td><td>2016 TRASM Performance minus 1.5% points</td><td>2016 TRASM Performance</td><td>2016 TRASM Performance plus 1.5% points or more</td><td>25.0%</td></tr><tr><td>Customer Service Performance—Domestic</td><td>+0% points</td><td>+2.5% points</td><td>+4.0% points or higher</td><td>12.50%</td></tr><tr><td>Customer Service Performance—International</td><td></td><td></td><td></td><td></td></tr><tr><td>Trans-Atlantic</td><td>+2.0% points</td><td>+3.0% points</td><td>+4.0% points or higher</td><td>6.25%</td></tr><tr><td>Trans-Pacific</td><td>+2.0% points</td><td>+3.0% points</td><td>+4.0% points or higher</td><td>3.125%</td></tr><tr><td>Latin America</td><td>+2.0% points</td><td>+3.0% points</td><td>+4.0% points or higher</td><td>3.125%</td></tr><tr><td>Return on Invested Capital</td><td>12.0%</td><td>14.0%</td><td>16.0% or higher</td><td>25.0%</td></tr><tr><td>Relative TSR Performance</td><td>25th percentile</td><td>50th percentile</td><td>75th percentile or higher</td><td>25.0%</td></tr></table>

Any portion of a Performance Award that does not vest at the end of the Performance Period will immediately lapse and become void. Payouts based on the above performance measures will be straight-line interpolated when actual performance results fall above Threshold and below Target or above Target and below Maximum.

(vi) Timing of Payment. The payout, if any, of any Performance Award that vests under Section 4(b)(v) will be made as soon after the end of the Performance Period as the payment amount can be finally determined, but in no event later than March 15, 2020, unless it is administratively impracticable to do so and such impracticability was not foreseeable at the end of 2019, in which case such payment shall be made as soon as administratively practicable after March 15, 2020.

(vii) Accelerated Vesting/Forfeiture upon Termination of Employment. The Performance Awards are subject to the following terms and conditions.

S = the portion of the Participant’s target Performance Award as of the Grant Date; and

T = the number of calendar months from January 1, 2017 to the date of such Termination of Employment (rounded up for any partial month).

If a Participant who is eligible for Retirement is or would be terminated by the Company without Cause, such Participant shall be considered to have been terminated by the Company without Cause for purposes of the 2017 LTIP rather than having retired, but only if the Participant acknowledges that, absent Retirement, the Participant would have been terminated by the Company without Cause. If, however, the employment of a Participant who is eligible for Retirement is terminated by the Company for Cause, then, regardless of whether the Participant is considered as a retiree for purposes of any other program, plan or policy of the Company, for purposes of the 2017 LTIP, the Participant’s employment shall be considered to have been terminated by the Company for Cause.

Subject to Section 4(d)(v)(F), upon a Participant’s Termination of Employment by reason of Retirement, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, the Pro Rata Option Portion of any Option Installment that is not exercisable at the time of such Termination of Employment (1) will vest and become exercisable, if applicable, under Section 4(d)(iv) in the same manner and to the same extent as if the Participant’s employment had continued and (2) the entire then exercisable portion of the Option shall be exercisable during the period: (I) beginning on the applicable Option Installment Vesting Date and (II) ending on the earlier of (x) the later of the third anniversary of (i) such Termination of Employment or (ii) the applicable Option Installment Vesting Date or (y) the Expiration Date. Pro Rata Option Portion has the meaning set forth in Section 4(d)(v)(A). Upon the Participant’s Termination of Employment by reason of Retirement, any portion of the Option that is not exercisable at the time of such termination, other than the Pro Rata Option Portion, shall be immediately forfeited.

Upon a Participant’s Termination of Employment due to death or Disability, any Option Installment that is not exercisable at the time of such Termination of Employment shall vest and become exercisable and the then exercisable portion of the Option shall be exercisable during the period: (1) beginning on the date of such Termination of Employment and (2) ending on the earlier of (I) the third anniversary of such Termination of Employment or (II) the Expiration Date.



(E) For Cause. Upon a Participant’s Termination of Employment by the Company for Cause, any unexercised portion of the Option shall be immediately forfeited, including any portion that was then exercisable.

(F) Retirement-Eligible Participants Who Incur a Termination of Employment for Other Reasons. If a Participant who is eligible for Retirement is or would be terminated by the Company without Cause, such Participant shall be considered to have been terminated by the Company without Cause for purposes of the 2017 LTIP rather than having retired, but only if the Participant acknowledges that, absent Retirement, the Participant would have been terminated by the Company without Cause. If, however, the employment of a Participant who is eligible for Retirement is terminated by the Company for Cause, then regardless of whether the Participant is considered as a retiree for purposes of any other program, plan or policy of the Company, for purposes of the 2017 LTIP, the Participant’s employment shall be considered to have been terminated by the Company for Cause.

(iv) Change in Control. Notwithstanding the foregoing and subject to Section 5, upon a Participant’s Termination of Employment by the Company without Cause or by the Participant for Good Reason (including the Termination of Employment of the Participant if he or she is employed by an Affiliate at the time the Company sells or otherwise divests itself of such Affiliate) on or after a Change in Control but prior to the second anniversary of such Change in Control, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, any Option Installment that is not exercisable at the time of such Termination of Employment shall vest and become exercisable, and the entire then exercisable portion of the Option shall be exercisable during the period (1) beginning on the date of such Termination of Employment and (2) ending on the earlier of (I) the third anniversary of such Termination of Employment or (II) the Expiration Date.

5. Potential Reduction in Payments Due to Excise Tax. In the event that a Participant becomes entitled to benefits under the 2017 LTIP, then such benefits, together with any payment or consideration in the nature of value or compensation to or for the Participant’s benefit under any other agreement with or plan of Delta, shall be subject to reduction as set forth in Section 4(e) of the Delta Air Lines, Inc. Officer and Director Severance Plan, which relates to the excise tax under Section 4999 of the Code.

6. Clawback. Notwithstanding anything to the contrary in the 2017 LTIP and subject to further amendment of this Section 7 to the extent required to be in compliance with any applicable law or regulations or Delta’s internal clawback policy, as it may be amended from time to time, if the Committee determines that a vice president or more senior officer Participant has engaged in fraud or misconduct that caused, in whole or in part, the need for a required restatement of Delta’s financial statements filed with the SEC, the Committee will review all incentive compensation awarded to or earned by the Participant, including, without limitation, any Award under the 2017 LTIP, with respect to fiscal periods materially affected by the restatement and may recover from the Participant all such incentive compensation to the extent that the Committee deems appropriate after taking into account the relevant facts and circumstances. Any recoupment hereunder may be in addition to any other remedies that may be available to Delta under applicable law, including, disciplinary action up to and including termination of employment.

7. Section 409A of the Code. To the extent required to be in compliance with Section 409A of the Code, and the regulations promulgated thereunder (together, “Section 409A”), notwithstanding any other provision of the 2017 LTIP or the Performance Compensation Plan, (a) any payment or benefit to which a Participant is eligible under the 2017 LTIP, including a Participant who is a “specified employee” as defined in Section 409A, shall be adjusted or delayed and (b) any term of the 2017 LTIP may be adjusted in such manner as to comply with Section 409A and maintain the intent of the 2017 LTIP to the maximum extent possible. More specifically, to the extent any payment provided to a Participant under the 2017 LTIP constitutes non-exempt deferred



compensation under Section 409A and the Participant is at the time of his termination of employment considered to be a “specified employee” pursuant to the Company’s policy for determining such employees, the payment of any such non excepted amount and the provision of such non exempted benefits will be delayed for six months following the Participant’s separation from service. Notwithstanding the foregoing, Delta shall not have any liability to any Participant or any other person if any payment is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A and does not satisfy the additional conditions applicable to nonqualified deferred compensation under Section 409A.

If, however, the employment of a Participant who is eligible for Retirement is terminated by the Company for Cause, then, regardless of whether the Participant is considered as a retiree for purposes of any other program, plan or policy of the Company, for purposes of the 2018 LTIP, the Participant’s employment shall be considered to have been terminated by the Company for Cause.



(vi) Change in Control. Notwithstanding the foregoing and subject to Section 5, upon a Participant’s Termination of Employment by the Company without Cause or by the Participant for Good Reason (including the Termination of Employment of the Participant if he or she is employed by an Affiliate at the time the Company sells or otherwise divests itself of such Affiliate) on or after a Change in Control but prior to the second anniversary of such Change in Control, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, any Restrictions in effect shall immediately lapse on the date of such Termination of Employment and be of no further force or effect as of such date.

(iv) Definitions.

(A) In General.

(1) The “Conversion Formula” will apply to convert from cash to Shares the payout, if any, of a Performance Award to a person who is an Executive Officer Participant at the time of such payout. First, the cash amount of the payout is calculated in the same manner as if the payout is being made in cash. Next, the cash amount is converted into a number of Shares based on the following formula:  \( (A \div B) \) , where:

A = the amount of the payout for the Performance Award if it is paid in cash; and

B = the closing price of a Share on the New York Stock Exchange on the later of (1) the date that the Committee approves the payouts, if any, of the



Performance Awards to the Executive Officer Participants following the Committee’s determination of the achievement of the payout criteria described in Section 4(b)(iii) and (2) the third business day following the date on which the Company publicly announces its annual financial results if this date is scheduled in the same month that the Committee approves such payouts, if any.

(2) “GAAP” means accounting principles generally accepted in the United States of America.

 \[  B=Industry Group Average TRASM. \] 

(2) “TRASM” for Delta shall be calculated by using Delta’s Available Seat Miles and Total Operating Revenue for the applicable periods and the following formula:  \( (A \div B) \) , where

 \[  A=Total Operating Revenue for2018,2019and2020;and \] 

 \[  B=Available Seat Miles for2018,2019and2020. \] 

(3) The “Industry Group Average TRASM” shall be calculated by using the aggregate Available Seat Miles and aggregate Total Operating Revenue for the applicable periods and the following formula:  \( (A \div B) \) , where

A = Total Operating Revenue for 2018, 2019 and 2020 for each of the members of the Industry Group; and

B = Available Seat Miles for 2018, 2019 and 2020 for each member of the Industry Group.

accordance with GAAP; provided, with respect to Delta, Total Operating Revenue shall exclude the portion of revenue associated with refinery sales to third parties net of exchange.

## (C) Customer Service Performance.

(1) The “Customer Service Performance” for Delta shall be measured based on the percentage point improvement in Delta’s average monthly Net Promoter Score (“NPS”) from the 2017 calendar year to the average monthly NPS over the Performance Period, with (A) Delta’s NPS performance attributable to domestic travel accounting for 50% of the measure and (ii) Delta’s NPS performance attributable to international travel accounting for 50% of the measure. The criteria and methodology used to determine Delta’s NPS is described in a document titled, “‘Net Promoter’: Measuring Customer Satisfaction at Delta,” which was previously reviewed by the Committee. Company management will periodically report to the Company’s Board of Directors regarding Delta’s NPS.

## (D) Return on Invested Capital.

(1)The “Return on Invested Capital” for Delta shall be calculated by using Delta’s Average Adjusted Total Net Operating Income and Average Invested Capital for the applicable periods and the following formula (A÷B), where:

A = Average Adjusted Total Net Operating Income for 2018, 2019 and 2020; and

B = Average Invested Capital for 2018, 2019 and 2020.

(2)“Average Adjusted Total Net Operating Income” means, subject to Section 4(b)(v)(B), (i) Delta’s average consolidated pre-tax income for the applicable periods based on its regularly prepared and publicly available statements of operations prepared in accordance with GAAP, but excluding (A) net interest expense; (B) items present in the line item “restructuring and other items” or such similar line item; (C) mark-to-market adjustments for hedges recorded in periods other than the settlement period; (D) other special, unusual or nonrecurring items which are disclosed in publicly available filings with the U.S. Securities and Exchange Commission (the “SEC”); and (E) implied interest in aircraft rent expense and amortized pension expense related to gains/losses that impact accumulated other comprehensive income (“AOCI”) multiplied by (ii) one minus Delta’s Effective Tax Rate for the applicable periods.

A = Adjusted Book Value of Equity; and

B = Adjusted Gross Debt.

“(5) “Adjusted Book Value of Equity” for Delta shall be calculated quarterly based on its regularly prepared internal financial statements (i) with an initial starting value for the quarter ending December 31, 2017 (the “Initial Value”) equal to the book value of equity determined in accordance with GAAP as of December 31, 2017, but excluding the impact of gains or losses as of December 31, 2017 associated with (1) the cumulative pension and other post-employment retirement benefits net balance recorded in AOCI; (2) the derivative contracts and associated items net balance recorded in AOCI; and (3) the deferred tax asset valuation allowance balance and (ii) using the following formula for each subsequent quarter thereafter,  \( (A+B+C) \) , where:

A = The Initial Value;

B = The cumulative amount starting as of January 1, 2018 and ending as of the last day of the applicable calendar quarter of the Company’s pre-tax income determined in accordance with GAAP, but (i) excluding: (1) items present in the line item “restructuring and other items” or such similar line item; (2) mark-to-market adjustments for hedges recorded in periods other than the settlement period; and (3) other special, unusual, or nonrecurring items which are disclosed in publicly available filings with the SEC and (ii) including expenses due to amortization of post-employment benefit losses in AOCI that have occurred during the Performance Period; and

C = in the event that the Company pays a dividend or issues or repurchases additional Common Stock for cash during the Performance Period (but excluding the exercise of any employee stock option for cash or any other issuance of Common Stock to employees), (i) the gross cash proceeds of the equity issuance or (ii) the gross cash payments for the equity repurchase or dividends, before adjustment for any applicable fees or charges associated therewith.

B = Annual aircraft rent expense multiplied by seven.

(E) Relative TSR Performance.



(1)“ Relative TSR Performance ” shall be calculated based on Delta’s TSR Percentile Ranking for the Performance Period.

(2)“TSR Percentile Ranking” means the percentage of the S&P 500 Companies with Total Shareholder Return for the Performance Period that is less than or equal to Delta’s Total Shareholder Return. If the Company’s Total Shareholder Return is the same as another company’s Total Shareholder Return, the Company shall be treated as having the higher Total Shareholder Return. The percentile ranking shall be carried out to two decimal places.

(3)“S&P 500 Companies” means all of the companies constituting the Standard & Poor’s 500 Index as of the first and last day of the Performance Period (excluding the Company) and which continue to be actively traded under the same ticker symbol on an established securities market through the end of the Performance Period.

(4)“Total Shareholder Return” or “TSR” means, for Delta and each of the S&P 500 Companies, (i) the change in the average closing market price of its common stock (as quoted in the principal market on which it is traded over the 20 trading days immediately preceding the first and last day of the Performance Period), plus dividends and other distributions paid, divided by (ii) the average closing market price over the 20 trading days immediately preceding the first day of the Performance Period, all of which are adjusted for any changes in equity structure, including, without limitation, stock splits and stock dividends, and assuming that all cash dividends and cash distributions are immediately reinvested in common stock of the subject company using the closing market price on the ex-dividend date.

## (v) Vesting.

(A) General. Subject to the terms of the Performance Compensation Plan, the 2018 LTIP and all other conditions included in any applicable Award Agreement, the Performance Award shall vest, as described in this Section 4(b)(v), as of the end of the Performance Period to the extent that the Company’s actual performance results meet or exceed Threshold level with respect to TRASM Performance, Customer Service Performance, Return on Invested Capital and/or Relative TSR Performance, as applicable and as described below. For purposes of TRASM Performance, the Company’s performance is compared against the Industry Group Average TRASM. For purposes of Relative TSR Performance, the Company’s performance is compared against the S&P 500 Companies.

(B) Committee’s Authority. In determining the TRASM for Delta and each member of the Industry Group and the Return on Invested Capital for Delta, the Committee shall make such adjustments with respect to any subject company as is necessary to ensure the results are comparable, including, without limitation, differences or changes in accounting policies, standards, practices, guidelines, reclassifications or restatements (for example, fuel hedging, purchase accounting adjustments associated with mergers, acquisitions or divestitures, or fresh start accounting as a result of emergence from bankruptcy). Without limiting the generality of the foregoing, the Committee shall (i) make such determinations based on financial data filed by the subject company with the SEC or otherwise and (ii) exclude from any calculation any



item of gain, loss or expense determined to be special or unusual in nature or infrequent in occurrence.

(C) Impact of Certain Events. A company shall be automatically removed from the Industry Group in the event that any of the following occur during or with respect to the Performance Period: (i) such company ceases to maintain or does not timely prepare publicly available statements of operations prepared in accordance with GAAP; (ii) such company is not the surviving entity in any merger, consolidation or other non-bankruptcy reorganization (or survives only as a subsidiary of an entity other than a previously wholly owned subsidiary of such company); (iii) such company sells, leases or exchanges all or substantially all of its assets to any other person or entity (other than a previously wholly owned subsidiary of such company); (iv) such company is dissolved and liquidated; or (v) more than 20% of such company's revenues (determined on a consolidated basis based on the regularly prepared and publicly available statements of operations of such company prepared in accordance with GAAP) for any fiscal year of such company are attributable to the operation of businesses other than such company's airline business and such company does not provide publicly available statements of operations with respect to its airline business that are separate from the statements of operations provided with respect to its other businesses.

(D) Transactions Between Airlines. To the extent reasonably practicable, in the event of a merger, consolidation or similar transaction during the Performance Period between Delta and any other airline, including a member of the Industry Group, or between any member of the Industry Group and any other airline, including another member of the Industry Group (an “Airline Merger”), TRASM for any such company involved in an Airline Merger will be calculated on a combined basis as if the Airline Merger had occurred on January 1, 2018, removing the effects of purchase accounting-related adjustments. Furthermore, to the extent reasonably practicable, in the event of an acquisition or divestiture or similar transaction during the Performance Period between Delta and any regional carrier or between any member of the Industry Group and any regional carrier (a “Regional Carrier Transaction”), TRASM and, as applicable, Return on Invested Capital for any such company involved in a Regional Carrier Transaction will be calculated to remove the impact of any reclassifications of costs from (or to) such company’s presentation of contract carrier expense to (or from) the other expense line items on the statement of operations (determined based on the regularly prepared and publicly available statements of operations of such company prepared in accordance with GAAP).



(E) Vesting/Performance Measures. The payment, if any, a Participant will receive in connection with the vesting of the Performance Award will be based on the following:

<table><tr><td rowspan="2"></td><td colspan="3">Performance Measure</td><td>Weighting</td></tr><tr><td>Threshold (50% of Target)</td><td>Target (100% of Target)</td><td>Maximum (200% of Target)</td><td></td></tr><tr><td>TRASM Performance</td><td>Average TRASM Performance* minus 1.5% points</td><td>Average TRASM Performance*</td><td>Average TRASM Performance* plus 1.5% points or more</td><td>25.0%</td></tr><tr><td>Customer Service Performance—Domestic</td><td>+0% points</td><td>+1.5% points</td><td>+2.5% points or higher</td><td>12.50%</td></tr><tr><td>Customer Service Performance—International</td><td></td><td></td><td></td><td></td></tr><tr><td>Trans-Atlantic</td><td>+0.0% points</td><td>+1.0% points</td><td>+2.0% points or higher</td><td>6.25%</td></tr><tr><td>Trans-Pacific</td><td>+0.0% points</td><td>+2.0% points</td><td>+3.5% points or higher</td><td>3.125%</td></tr><tr><td>Latin America</td><td>+0.0% points</td><td>+1.5% points</td><td>+2.5% points or higher</td><td>3.125%</td></tr><tr><td>Return on Invested Capital</td><td>11.0%</td><td>13.0%</td><td>15.0% or higher</td><td>25.0%</td></tr><tr><td>Relative TSR Performance</td><td>25th percentile</td><td>50th percentile</td><td>75th percentile or higher</td><td>25.0%</td></tr></table>

 \( ^{*} \)  Average TRASM Performance equals the average TRASM Performance for 2015 – 2017.

Any portion of a Performance Award that does not vest at the end of the Performance Period will immediately lapse and become void. Payouts based on the above performance measures will be straight-line interpolated when actual performance results fall above Threshold and below Target or above Target and below Maximum.

(vi) Timing of Payment. The payout, if any, of any Performance Award that vests under Section 4(b)(v) will be made as soon after the end of the Performance Period as the payment amount can be finally determined, but in no event later than March 15, 2021, unless it is administratively impracticable to do so and such impracticability was not foreseeable at the end of 2020, in which case such payment shall be made as soon as administratively practicable after March 15, 2021.

(vii) Accelerated Vesting/Forfeiture upon Termination of Employment. The Performance Awards are subject to the following terms and conditions.

(A) Without Cause or For Good Reason. Upon a Participant’s Termination of Employment by the Company without Cause or by the Participant for Good Reason (including the Termination of Employment of the Participant if he or she is employed by an Affiliate at the time the Company sells or otherwise divests itself of such Affiliate), subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, the Participant’s target Performance Award will be recalculated and will be the result of the following formula (the “Adjusted Performance Award”):  \( S \times (T \div 36) \)  where,



S = the portion of the Participant’s target Performance Award as of the Grant Date; and

T = the number of calendar months from January 1, 2018 to the date of such Termination of Employment (rounded up for any partial month).

Thereafter, the Participant will be eligible to receive a payment, if any, in cash based on the Adjusted Performance Award which will vest and become payable under Section 4(b)(v) in the same manner and to the same extent as if the Participant’s employment had continued.

(B) Voluntary Resignation. Upon a Participant’s Termination of Employment by reason of a voluntary resignation (other than for Good Reason or Retirement) prior to the end of the workday on December 31, 2020, the Participant will immediately forfeit any unpaid portion of the Performance Award as of the date of such Termination of Employment. In the event a Participant incurs a Termination of Employment by reason of a voluntary resignation (other than for Good Reason or Retirement) on or after January 1, 2021, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, the Participant will remain eligible for any unpaid Performance Award, which award will vest and become payable under Section 4(b)(v) in the same manner and to the same extent as if the Participant’s employment had continued.

(C) Retirement. Subject to Section 4(b)(vii)(F), upon a Participant’s Termination of Employment due to Retirement, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, the Participant’s target Performance Award will be recalculated in accordance with the formula set forth in Section 4(b)(vii)(A). Thereafter, the Participant will be eligible to receive a payment, if any, in cash based on the Adjusted Performance Award which will vest and become payable under Section 4(b)(v) in the same manner and to the same extent as if the Participant’s employment had continued.

(D) Death or Disability. Upon a Participant’s Termination of Employment due to death or Disability, the Participant’s Performance Award will immediately become vested at the target level and such amount will be paid in cash as soon as practicable thereafter to the Participant or the Participant’s estate, as applicable.

(E) For Cause. Upon a Participant’s Termination of Employment by the Company for Cause, the Participant will immediately forfeit any unpaid portion of the Performance Award as of the date of such Termination of Employment.

(F) Retirement-Eligible Participants Who Incur a Termination of Employment for Other Reasons. If a Participant who is eligible for Retirement is or would be terminated by the Company without Cause, such Participant shall be considered to have been terminated by the Company without Cause for purposes of the 2018 LTIP rather than having retired, but only if the Participant acknowledges that, absent Retirement, the Participant would have been terminated by the Company without Cause. If, however, the employment of a Participant who is eligible for Retirement is terminated by the Company for Cause, then, regardless of whether the Participant is considered as a retiree for purposes of any other program, plan or policy of the Company, for purposes of the 2018 LTIP, the Participant’s employment shall be considered to have been terminated by the Company for Cause.



(viii) Change in Control. Notwithstanding the foregoing and subject to Section 5, upon a Participant’s Termination of Employment by the Company without Cause or by the Participant for Good Reason (including the Termination of Employment of the Participant if he or she is employed by an Affiliate at the time the Company sells or otherwise divests itself of such Affiliate) on or after a Change in Control but prior to the second anniversary of such Change in Control, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, the Participant’s outstanding Performance Award shall immediately become vested at the target level and such amount will be paid in cash to the Participant as soon as practicable. With respect to any Participant who incurs a Termination of Employment by the Company without Cause or who resigns for Good Reason prior to a Change in Control, if a Change in Control occurs thereafter during the Performance Period, such Participant’s Adjusted Performance Award, will immediately become vested and be paid in cash to the Participant as soon as practicable.

## (c) Restricted Stock Units

(i) Award Grant. A Participant may receive Restricted Stock Units as specified in the Participant’s Award Agreement (the “RSU”).

(ii) Grant Date. The Grant Date of the RSUs will be determined in accordance with the Company’s Equity Award Grant Policy, as in effect from time to time, and set forth in the Participant’s Award Agreement.

(iii) Risk of Forfeiture. Until an RSU becomes vested, a Participant will not be permitted to sell, exchange, assign, transfer or otherwise dispose of the RSU, and the RSU will be subject to forfeiture as set forth below.

Upon a Participant’s Termination of Employment by the Company without Cause or by the Participant for Good Reason, any unvested RSUs, other than the Pro Rata RSU Portion, shall be immediately forfeited.

“ Pro Rata RSU Portion ” means, with respect to any RSU Installment that is not vested at the time of a Participant’s Termination of Employment, the number of RSUs covered by such RSU Installment multiplied by a fraction (i) the numerator of which is the number of calendar months  \( ^{5} \)  from the Grant Date to the date of such Termination of Employment, rounded up for any partial month and (ii) the denominator of which is twelve (12) for the First RSU Installment, twenty-four (24) for the Second RSU Installment and thirty-six (36) for the Third RSU Installment. \( ^{6} \) 

(B) Voluntary Resignation. Upon a Participant’s Termination of Employment by reason of a voluntary resignation (other than for Good Reason or Retirement), any unvested portion of the RSUs shall be immediately forfeited.

(C) Retirement. Subject to Section (4)(c)(v)(F), upon a Participant’s Termination of Employment by reason of Retirement, with respect to any RSU Installment that is not then vested, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, a number of RSUs equal to the Pro Rata RSU Portion will become immediately vested as of the date of such Termination of Employment.

If, however, the employment of a Participant who is eligible for Retirement is terminated by the Company for Cause, then regardless of whether the Participant is considered a retiree for purposes of any other program, plan or policy of the Company, for purposes of this Agreement, the Participant’s employment shall be considered to have been terminated by the Company for Cause.

(vi) Change in Control. Notwithstanding the foregoing and subject to Section 5, upon a Participant’s Termination of Employment by the Company without Cause or by the Participant for Good Reason (including the Termination of Employment of the Participant if he or she is employed by an Affiliate at the time the Company sells or otherwise divests itself of such Affiliate) on or after a Change in Control, but prior to the second anniversary of such Change in Control, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, any unvested portion of the RSUs will immediately vest as of the date of such Termination of Employment.

(vii) Dividend Equivalents.

Pro Rata Option Portion has the meaning set forth in Section 4(d)(v)(A). Upon the Participant’s Termination of Employment by reason of Retirement, any portion of the Option that is not exercisable at the time of such termination, other than the Pro Rata Option Portion, shall be immediately forfeited.

If, however, the employment of a Participant who is eligible for Retirement is terminated by the Company for Cause, then regardless of whether the Participant is considered as a retiree for purposes of any other program, plan or policy of the Company, for purposes of the 2018 LTIP, the Participant’s employment shall be considered to have been terminated by the Company for Cause.

(vi) Change in Control. Notwithstanding the foregoing and subject to Section 5, upon a Participant’s Termination of Employment by the Company without Cause or by the Participant for Good Reason (including the Termination of Employment of the Participant if he or she is employed by an Affiliate at the time the Company sells or otherwise divests itself of such Affiliate) on or after a Change in Control but prior to the second anniversary of such Change in Control, subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, any Option Installment that is not exercisable at the time of such Termination of Employment shall vest and



become exercisable, and the entire then exercisable portion of the Option shall be exercisable during the period (1) beginning on the date of such Termination of Employment and (2) ending on the earlier of (I) the third anniversary of such Termination of Employment or (II) the Expiration Date.

5. Potential Reduction in Payments Due to Excise Tax. In the event that a Participant becomes entitled to benefits under the 2018 LTIP, then such benefits, together with any payment or consideration in the nature of value or compensation to or for the Participant’s benefit under any other agreement with or plan of Delta, shall be subject to reduction as set forth in Section 4(e) of the Delta Air Lines, Inc. Officer and Director Severance Plan, which relates to the excise tax under Section 4999 of the Code.

6. Clawback. Notwithstanding anything to the contrary in the 2018 LTIP and subject to further amendment of this Section 6 to the extent required to be in compliance with any applicable law or regulations or Delta’s internal clawback policy, as it may be amended from time to time, if the Committee determines that a vice president or more senior officer Participant has engaged in fraud or misconduct that caused, in whole or in part, the need for a required restatement of Delta’s financial statements filed with the SEC, the Committee will review all incentive compensation awarded to or earned by the Participant, including, without limitation, any Award under the 2018 LTIP, with respect to fiscal periods materially affected by the restatement and may recover from the Participant all such incentive compensation to the extent that the Committee deems appropriate after taking into account the relevant facts and circumstances. Any recoupment hereunder may be in addition to any other remedies that may be available to Delta under applicable law, including, disciplinary action up to and including termination of employment.

7. Section 409A of the Code. To the extent required to be in compliance with Section 409A of the Code, and the regulations promulgated thereunder (together, “Section 409A”), notwithstanding any other provision of the 2018 LTIP or the Performance Compensation Plan, (a) any payment or benefit to which a Participant is eligible under the 2018 LTIP, including a Participant who is a “specified employee” as defined in Section 409A, shall be adjusted or delayed and (b) any term of the 2018 LTIP may be adjusted in such manner as to comply with Section 409A and maintain the intent of the 2018 LTIP to the maximum extent possible. More specifically, to the extent any payment provided to a Participant under the 2018 LTIP constitutes non-exempt deferred compensation under Section 409A and the Participant is at the time of his termination of employment considered to be a “specified employee” pursuant to the Company’s policy for determining such employees, the payment of any such non-exempt amount and the provision of such non-exempt benefits will be delayed for six months following the Participant’s separation from service. Notwithstanding the foregoing, Delta shall not have any liability to any Participant or any other person if any payment is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A and does not satisfy the additional conditions applicable to nonqualified deferred compensation under Section 409A.

Capitalized terms that are used but not defined in the MIP shall have the meaning ascribed to them in the Performance Compensation Plan.

2. Plan Administration.

The Committee shall have such powers as may be necessary to discharge its duties hereunder, including, without limitation, the following powers and duties, but subject to the terms of the MIP:

(i) authority to construe and interpret the terms of the MIP and to determine eligibility, awards and the amount, manner and time of payment of any awards hereunder;

(ii) authority to prescribe forms and procedures for purposes of MIP participation and distribution of awards;

(iv) authority at any time prior to a Change in Control to eliminate or reduce the actual payout to any Participant in the MIP.

(b) Any rule or decision by the Committee (or its delegate) that is not inconsistent with the provisions of the MIP shall be conclusive and binding on all persons and shall be given the maximum deference permitted by law.

3. Eligibility. All Delta employees worldwide who are officers, managing directors (grade 13), directors (grade 12), general managers (grade 11), grade 10 or grade 8 (other than employees who participate in a sales incentive plan or other major functional incentive plan, as may be in effect from time to time) are eligible to participate in the MIP (“Participants”).

## 4. MIP Awards.

(a) General. The MIP award (the “MIP Award”) each Participant receives, if any, will be based on: (i) the Participant’s Target MIP Award, as defined below; (ii) the level of achievement within each applicable performance measure; and (iii) the occurrence of a payout for 2018 under the Company’s broad-based employee profit sharing program (the “Profit Sharing Program”), as described below. Certain additional requirements will apply to any Participant who is employed by the Company as an executive vice president or more senior officer of the Company (“Executive Officer Participant”), as discussed in Section 7(b).

(b) Performance Measures. The performance measures used will be one or more of financial, operational (“Operational Performance”), leadership effectiveness (“Leadership Effectiveness Performance”) and individual performance (“Individual Performance”). Financial performance will be comprised of two separate measures, one based solely on the Company’s performance (“Absolute Financial Performance”) and the other based on the Company’s performance relative to a comparator group (“Relative Financial Performance”) Achievement under each performance measure may range from below threshold, at which there is no payout, to the maximum performance level, at which the payout will be greater than the target level, subject to Section 4(c).

(c) Interaction with Profit Sharing Program and Individual Performance Measure. If there is no payout under the Profit Sharing Program for 2018, (i) no amount will be paid with respect to Absolute Financial Performance to any Participant regardless of whether Delta meets or exceeds that performance measure and (ii) for general manager level (grade 11) Participants and above, the actual MIP Award, if any, will not exceed such Participant’s Target MIP Award (as defined below). In addition, if a Participant’s performance under the Individual Performance Measure (applicable to Participants who are not officers) is not satisfactory, no amount will be paid with respect to Absolute Financial Performance, Relative Financial Performance and/or Operational Performance to such Participant regardless of whether Delta meets or exceeds those performance measures.

(d) Target MIP Awards. The Target MIP Award for each Participant will be expressed as a percentage of the Participant’s Annual Base Salary (the “Target MIP Award”) as determined by the Committee and will be communicated to Participants in such manner as the Committee deems appropriate. Subject to Section 8, “Annual Base Salary” means the Participant’s 2018 annual base salary as in effect on December 31, 2018.



5. Weighting of Performance Measures. Subject to Section 8, a percentage of each Participant’s Target MIP Award is allocated to one or more of Absolute Financial Performance, Relative Financial Performance, Operational Performance, Leadership Effectiveness Performance and/or Individual Performance based on the Participant’s employment level, as follows:

<table><tr><td colspan="6">Performance Measures and Weightings</td></tr><tr><td>Employment Level</td><td>% of Target MIP Award allocated to Absolute Financial Performance</td><td>% of Target MIP Award allocated to Relative Financial Performance</td><td>% of Target MIP Award allocated to Operational Performance</td><td>% of Target MIP Award allocated to Leadership Effectiveness Performance</td><td>% of Target MIP Award allocated to Individual Performance</td></tr><tr><td>CEO</td><td>50%</td><td>25%</td><td>25%</td><td>0%</td><td>0%</td></tr><tr><td>President/SEVP</td><td>50%</td><td>25%</td><td>25%</td><td>0%</td><td>0</td></tr><tr><td>EVP</td><td>50%</td><td>25%</td><td>25%</td><td>0%</td><td>%</td></tr><tr><td>CIO and SVP - Supply Chain Management &amp; Fleet</td><td>50%</td><td>25%</td><td>25%</td><td>0%</td><td>0</td></tr><tr><td>SVP</td><td>50%</td><td>15%</td><td>25%</td><td>10%</td><td>0</td></tr><tr><td>VP</td><td>50%</td><td>15%</td><td>25%</td><td>10%</td><td>%</td></tr><tr><td>Managing Director (Grade 13)</td><td>35%</td><td>10%</td><td>15%</td><td>0%</td><td>40%</td></tr><tr><td>Director (Grade 12)</td><td>35%</td><td>10%</td><td>15%</td><td>0%</td><td>%</td></tr><tr><td>General Manager (Grade 11)</td><td>25%</td><td>10%</td><td>15%</td><td>0%</td><td>50%</td></tr><tr><td>Grade 10</td><td>0%</td><td>0%</td><td>0%</td><td>0%</td><td>100%</td></tr><tr><td>Grade 8</td><td>0%</td><td>0%</td><td>0%</td><td>0%</td><td>100</td></tr></table>

6. The Performance Measures—Threshold, Target and Maximum Payout Levels. The Target MIP Award and the amounts paid in connection with target levels of Absolute Financial, Relative Financial, Operational, Leadership Effectiveness and Individual Performances, are based on the achievement of the target performance level with respect to each applicable performance measure (except that Absolute Financial Performance also requires a payout under the Profit Sharing Program for 2018). A Participant’s actual MIP Award may be greater or less than the target amount based on whether performance under one or more of the performance measures applicable to the Participant exceeds or is below target performance, subject to Section 4(c). This is explained in more detail below.

(a) Absolute Financial Performance Measure. The Absolute Financial Performance measure for 2018 is based on Delta’s Pre-Tax Income (as defined below). The following table describes the performance ranges and award payout levels for 2018 Absolute Financial Performance, subject to Section 4(c):

<table><tr><td></td><td>Threshold</td><td>Target</td><td>Maximum</td></tr><tr><td>% of Target Absolute Financial Performance Measure Paid</td><td>50%</td><td>100%</td><td>200%</td></tr><tr><td>Required 2018 Pre-Tax Income</td><td>$6,504 Million</td><td>$7,869 Million</td><td>$8,794 Million</td></tr></table>

Payouts will be straight-line interpolated when Pre-Tax Income results fall above Threshold and below Target or above Target and below Maximum.



“Pre-Tax Income” will be the amount of Pre-Tax Income, if any, determined under the Profit Sharing Program for 2018. \( ^{1} \) 

(b) Relative Financial Performance Measure. The Relative Financial Performance measure will be measured based on the comparison of Delta’s Annual Pre-Tax Income Margin for the 2018 calendar year relative to the Composite Performance of the members of the Industry Composite Group for the 2018 calendar year (as such capitalized terms are defined below). The following table describes the performance ranges and payout levels for 2018 Relative Financial Performance, subject to Section 4(c):

<table><tr><td></td><td>Threshold</td><td>Target</td><td>Maximum</td></tr><tr><td>% of Target Relative Financial Performance Measure Paid</td><td>50%</td><td>100%</td><td>200%</td></tr><tr><td>Delta’s 2018 Annual Pre-Tax Income Margin relative to Composite Performance of Industry Composite Group for the same period</td><td>Composite Performance</td><td>+2.5 points above Composite Performance</td><td>+3.5 points above Composite Performance</td></tr></table>

Payouts based on Relative Financial Performance will be straight-line interpolated when actual performance results fall above Threshold and below Target or above Target and below Maximum.

“Annual Pre-Tax Income Margin” for Delta and each member of the Industry Composite Group shall be calculated by using the subject company’s Pre-Tax Income and Total Operating Revenue for the 2018 calendar year and the following formula: (A÷B), where:

A = Pre-Tax Income for 2018; and

B = Total Operating Revenue for 2018.

“Composite Performance” means, for purposes of determining the total Annual Pre-Tax Income Margin for the Industry Composite Group, the result obtained by treating the members of the Industry Composite Group as if they were one combined entity.

“Industry Composite Group” means Alaska Air Group, Inc., American Airlines Group, Inc., JetBlue Airways Corporation, Southwest Airlines, Co., and United Continental Holdings, Inc.

“Pre-Tax Income” means the subject company’s consolidated pre-tax income based on its regularly prepared and publicly available statements of operations prepared in accordance with GAAP, but excluding mark-to-market adjustment for hedges recorded in periods other than the settlement period.

“Total Operating Revenue” means the subject company’s total operating revenue based on its regularly prepared and publicly available statements of operations prepared in accordance with GAAP; provided, with respect to Delta, Total Operating Revenue shall exclude the portion of revenue associated with refinery sales to third parties net of exchange.



In determining the Annual Pre-Tax Income Margin for Delta and each member of the Industry Composite Group, the Committee shall make such adjustments with respect to any subject company as is necessary to ensure the results are comparable, including, without limitation, differences or changes in accounting policies, standards, practices, guidelines, reclassifications or restatements (for example, fuel hedging, purchase accounting adjustments associated with mergers, acquisitions or divestures, or fresh start accounting as a result of emergence from bankruptcy). Without limiting the generality of the foregoing, the Committee shall (i) make such determinations based on financial data filed by the subject company with the U.S. Securities and Exchange Commission or otherwise and (ii) exclude from any calculation any item of gain, loss or expense determined to be special or unusual in nature or infrequent in occurrence.

A company shall be automatically removed from the Industry Composite Group in the event that any of the following occur during or with respect to the 2018 calendar year: (i) such company ceases to maintain or does not timely prepare publicly available statements of operations prepared in accordance with GAAP; (ii) such company is not the surviving entity in any merger, consolidation or other nonbankruptcy reorganization (or survives only as a subsidiary of an entity other than a previously wholly owned subsidiary of such company); (iii) such company sells, leases or exchanges all or substantially all of its assets to any other person or entity (other than a previously wholly owned subsidiary of such company); (iv) such company is dissolved and liquidated; or (v) more than 20% of such company's revenues (determined on a consolidated basis based on the regularly prepared and publicly available statements of operations of such company prepared in accordance with GAAP) for any fiscal year of such company are attributable to the operation of businesses other than such company's airline business and such company does not provide publicly available statements of operations with respect to its airline business that are separate from the statements of operations provided with respect to its other businesses.

To the extent reasonably practicable, in the event of a merger, consolidation or similar transaction during the 2018 calendar year between Delta and any other airline, including a member of the Industry Composite Group, or between any member of the Industry Composite Group and any other airline, including another member of the Industry Composite Group (an “Airline Merger”), Annual Pre-Tax Income Margin for any such company involved in an Airline Merger will be calculated on a combined basis as if the Airline Merger had occurred on January 1, 2018, removing the effects of purchase accounting-related adjustments. Furthermore, to the extent reasonably practicable, in the event of an acquisition or divestiture or similar transaction during 2018 calendar year between Delta and any regional carrier or between any member of the Industry Composite Group and any regional carrier (a “Regional Carrier Transaction”), Annual Pre-Tax Income Margin for any such company involved in a Regional Carrier Transaction will be calculated to remove the impact of any reclassifications of costs from (or to) such company’s presentation of contract carrier expense to (or from) the other expense line items on the statement of operations (determined based on the regularly prepared and publicly available statements of operations of such company prepared in accordance with GAAP).

(c) Operational Performance Measures. The Operational Performance measures for 2018 are based on both Delta and Delta Connection operational performance, with (i) Delta’s operational performance accounting for 75% of the measure and (ii) Delta Connection performance accounting for 25% of the measure. Delta’s Operational Performance is based on the number of times during 2018 that Delta meets or exceeds its monthly goals under the broad-based employee shared rewards program (the “Shared Rewards Program”). Delta Connection’s Operational Performance is based on the number of times during 2018 that the Delta Connection carriers meet or exceed their monthly operational goals for (x) completion factor and (y) on-time arrival performance (the “Delta Connection Goals”). The Delta Connection Goals and the methodology for determining whether these goals are met are described in Exhibit A hereto. The following table describes the performance ranges and award payout levels for 2018 Operational Performance, subject to Section 4(c):



<table><tr><td></td><td>Threshold</td><td>Target</td><td>Maximum</td></tr><tr><td>Shared Rewards Program</td><td></td><td></td><td></td></tr><tr><td>% of Target Payout for this Performance Measure (75% Weighting)</td><td>37.50%</td><td>75%</td><td>150%</td></tr><tr><td>Number of monthly Shared Rewards Program goals actually met during 2018</td><td>21</td><td>28</td><td>35 or more</td></tr><tr><td>Delta Connection Goals</td><td></td><td></td><td></td></tr><tr><td>% of Target Payout for this Performance Measure (25% Weighting)</td><td>12.50%</td><td>25%</td><td>50%</td></tr><tr><td>Number of Delta Connection Goals actually met during 2018</td><td>9</td><td>14</td><td>19 or more</td></tr></table>

Payouts based on the Shared Rewards Program and Delta Connection Goals will be straight-line interpolated when actual performance results fall above Threshold and below Target or above Target and below Maximum.

(d) Leadership Effectiveness Performance Measure. The Leadership Effectiveness Performance measure (generally applicable to Participants who are vice presidents or senior vice presidents) for 2018 will be based on an evaluation of whether a Participant has demonstrated leadership attributes and results during 2018, including, among other things, supporting diversity, providing talent management, meeting financial and headcount budget, improving employee engagement and being a role model for the Rules of the Road. The performance ranges and award payout levels will be determined by the Committee, subject to Section 4(c).

(e) Individual Performance Measure. The Individual Performance measure (applicable to Participants who are not officers) is generally determined by each Participant’s performance evaluation at the end of 2018. The performance ranges and award payout levels will be determined by the Committee, subject to Section 4(c).

## 7. Timing of Award Payments.

(a) In General. Subject to Sections 7(b) and 8(a), any payouts to a Participant under the MIP for 2018 will be made in cash as soon as practicable after (i) the Committee certifies the achievement of the required Absolute Financial Performance, Relative Financial Performance and Operational Performance results and (ii) where applicable, Leadership Effectiveness Performance results have been determined and individual performance has been evaluated, but in no event later than March 15, 2019, unless it is administratively impracticable to do so, and such impracticability was unforeseeable at the end of 2018, in which case such payment shall be made as soon as administratively practicable after March 15, 2019. Further, unless a payout for 2018 under the Profit Sharing Program occurs after March 15, 2019, any payout under the 2018 MIP will not be made prior to a payout for 2018 under the Profit Sharing Program; provided, however, if it is determined there will be no payout for 2018 under the Profit Sharing Program, any MIP Awards that are payable based on Relative Financial Performance, Operational Performance, Leadership Effectiveness Performance or Individual Performance will be paid as soon as practicable thereafter, but in no event later than March 15, 2018, unless it is administratively impracticable to do so, and such impracticability was unforeseeable at the end of 2018, in which case such payment shall be made as soon as administratively practicable after March 15, 2019.

(b) Executive Officer Participants. Payouts under the MIP to Participants who, as of December 31, 2018, are Executive Officer Participants will be subject to the following terms and conditions:

(i) Payment in Restricted Stock. If there is no payout under the Profit Sharing Program for 2018, any payout under the MIP to an Executive Officer Participant will be made in shares of Restricted Stock rather than in cash, with the number of shares of Restricted Stock being equal to the result of the following formula (“MIP Restricted Stock”): (A÷B), where  \( ^{2} \) : If this formula results in any fractional share, the MIP Restricted Stock will be rounded up to the next highest ten shares.



A = the amount of the payout to the Executive Officer Participant under the MIP had the payout been made in cash; and

B = the closing price of a Share on the New York Stock Exchange on the later of (1) the date that the Committee approves the payouts, if any, to the Executive Officer Participants under the MIP following the Committee’s certification of the achievement of the required performance measures as described in Section 7(a) and (2) the third business day following the date on which the Company publicly announces its annual financial results if this date is scheduled in the same month that the Committee approves such payouts, if any.

(ii) Lapsing of Restrictions; Forfeiture. Until the restrictions imposed by this Section 7(b)(ii) (the “Restrictions”) have lapsed pursuant to the terms below, an Executive Officer Participant will not be permitted to sell, exchange, assign, transfer or otherwise dispose of the MIP Restricted Stock, and the MIP Restricted Stock will be subject to forfeiture as set forth below.

(A) The Restrictions shall lapse and be of no further force or effect on the earlier of the date (1) there is a payout under the Profit Sharing Program unless, prior to such payout, the Executive Officer Participant incurs a Disqualifying Termination of Employment or (2) an Executive Officer Participant incurs a Qualifying Termination of Employment. The MIP Restricted Stock will be immediately forfeited if, prior to the lapsing of the Restrictions, the Executive Officer Participant incurs a Disqualifying Termination of Employment.

(B) “Disqualifying Termination of Employment” means an Executive Officer Participant’s Termination of Employment by the Company for Cause.

(C) “Qualifying Termination of Employment” means an Executive Officer Participant’s Termination of Employment (1) by the Company without Cause or (2) due to death or Disability.

(D) For purposes of this Section 7(b)(ii), if an Executive Officer Participant incurs a Termination of Employment by reason of (1) a voluntary resignation (including the Termination of Employment by the Participant if he or she is employed by an Affiliate at the time the Company sells or otherwise divests itself of such Affiliate) or (2) Retirement, the Restrictions shall lapse and be of no further force or effect on the date there is a payout under the Profit Sharing Program as if such Executive Officer Participant’s employment had continued through such date.

(iii) Dividends. In the event a cash dividend shall be paid in respect of Shares at a time the Restrictions on the MIP Restricted Stock have not lapsed, the Participant shall be eligible to receive the dividend upon the lapse of the Restrictions. The Restrictions shall apply to any such dividend.

(iv) Performance Compensation Plan; Written Notice. The MIP Restricted Stock will otherwise be subject to the terms of the Performance Compensation Plan. In the event any Executive Officer Participant’s MIP Award is converted to MIP Restricted Stock, such Participant will receive a written notice of such conversion with the details thereof as soon as practicable after the MIP payment date.



## 8. Change in Employment Status.

## (a) Termination of Employment.

(i) A Termination Event in 2018—General. Except as expressly set forth in this Section 8, in the event a Participant’s employment with Delta terminates for any reason prior to the end of the workday on December 31, 2018, such Participant will be ineligible for any award under the MIP. In other words, if a Participant is employed according to Company records through the end of the workday on December 31, 2018, the Participant will be eligible for any award earned under the MIP for 2018, including, if applicable, MIP Restricted Stock.

(ii) Termination on or after January 1, 2019. Subject to Section 7(b), a Participant who incurs a Termination of Employment for any reason other than for Cause on or after January 1, 2019 will remain eligible for any unpaid MIP Award, which award will be paid according to the terms of Section 7(a). A Participant who is terminated by the Company for Cause on or after January 1, 2019 will forfeit any unpaid MIP Award.

## (iii) Pro Rata MIP Payment.

(A) Disability or Retirement. This Section 8(a)(iii)(A) applies to any Participant who incurs a Termination of Employment prior to January 1, 2019 due to the Participant’s Disability or Retirement. Subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, such Participant will be eligible to receive a MIP Award based on an adjusted annual base salary amount, but otherwise in the same manner, to the same extent and at the same time as the Participant would have received such MIP Award if such Participant’s employment had continued through December 31, 2018 (i.e., based on achievement of applicable performance measures). The Individual Performance Measure will be calculated based on target level performance, or, at the discretion of the Company, a higher level based on the Participant’s most recent performance evaluation prior to the Termination of Employment. The Participant’s Annual Base Salary will be the result of the following formula:  \( (X \times Y / 12) \) , where:

X = the Participant’s annual base salary as in effect as of the date of Termination of Employment; and

Y = the number of calendar months the Participant was actively employed by Delta during 2018 in a MIP-eligible position, rounded up for any partial month. \( ^{3} \)



(B) Termination of Employment Without Cause or Resulting in Benefits under the Severance Plans. This Section 8(a)(iii)(B) applies to any Participant who incurs a Termination of Employment prior to January 1, 2019 due to either (1) a Termination of Employment by the Company without Cause or (2) for any other reason that entitles such Participant to benefits under the Delta Air Lines, Inc. Officer and Director Severance Plan or any other Company-sponsored severance plan in which a Participant is eligible to participate (the “Severance Plans”). Subject to the Participant’s execution of a waiver and release of claims in a form and manner satisfactory to the Company, such Participant will be eligible to receive a MIP Award based on an adjusted annual base salary amount, but otherwise in the same manner, to the same extent and at the same time as the Participant would have received such MIP Award if such Participant’s employment had continued through December 31, 2018 (i.e., based on achievement of applicable performance measures). The Individual Performance Measure will be calculated based on target level performance, or, at the discretion of the Company, a higher level based on the Participant’s most recent performance evaluation prior to the Termination of Employment. The Participant’s Annual Base Salary will be determined in accordance with the formula set forth in Section 8(a)(iii)(A).

(C) Death. This Section 8(a)(iii)(C) applies to any Participant who incurs a Termination of Employment prior to January 1, 2019 due to the Participant’s death. The Participant’s estate will be eligible to receive a Pro Rata MIP Payment made in cash as soon as practicable after the Participant’s Termination of Employment, but in no event later than 2½ months following the end of the year in which the Termination of Employment occurs. “Pro Rata MIP Payment” means the result of the following formula:  \( (W \times Z / 12) \) , where:

W = the Participant’s Target MIP Award; and

Z = the number of calendar months the Participant was actively employed by Delta during 2018 in a MIP-eligible position, rounded up for any partial month.

(b) Other Changes in Employment Status. The terms of this Section 8(b) shall apply to circumstances involving new hires, promotions, demotions, transfers or leaves of absence during 2018. After a Participant’s Target MIP Award is determined under this Section 8(b), the appropriate weighting of performance measures will apply to each portion of such Target MIP Award as set forth in Section 5. For partial calendar months, the change in employment status will be considered effective as of the 1 \( ^{st} \)  day of the month in which there is a change in status; provided, however, in the event that a Participant was (i) on a disability leave of absence for a period of less than one calendar month during 2018 and (ii) actively at work for at least one full day during such calendar month, the Participant will be deemed to have been actively employed in a MIP-eligible position for the entire calendar month. The end of year performance evaluation will apply to any Individual Performance measure applicable to the Participant unless the Participant is no longer subject to the such evaluation process after the change in employment status, in which case the most recent performance evaluation will apply. Any MIP Awards payable under this Section 8(b) will be paid at the same time and in the same manner as such awards are paid to active Participants, subject to Section 7(b).

(i) New Hires. With respect to any individual who becomes employed by Delta as a grade 8 or any more senior MIP-eligible position during 2018 but after January 1, 2018, such individual will be a Participant in the MIP and will be eligible to receive an award under the MIP for 2018; provided, that such Participant’s Annual Base Salary will be the result of the following formula:  \( (X \times Y / 12) \) , where:



Y = the number of calendar months the Participant was actively employed by Delta in a MIP-eligible position during 2018, rounded up for any partial month.

(ii) Promotions. Participants who are either promoted into a MIP-eligible employment level or promoted into a higher level of MIP participation during 2018 will have their Target MIP Award calculated based on their annual base salary at each MIP-eligible employment level (measured as of the date immediately prior to the date the promotion is considered effective for purposes of the MIP, if applicable, as described in the first paragraph of Section 8(b), and as of December 31, 2018) and the number of calendar months they were employed in each such capacity, multiplied by the relevant total target award percentage applicable to their position or positions during the relevant period.

(iii) Demotions. Participants who are either demoted to a position that is not eligible to participate in the MIP or demoted to a lower level of MIP participation during 2018 will have their Target MIP Award calculated based on their annual base salary at each MIP-eligible job level (measured as of the date immediately prior to the date the demotion is considered effective for purposes of the MIP, as described in the first paragraph of Section 8(b), and, if applicable, as of December 31, 2018) and the number of calendar months they were employed in each such capacity, multiplied by the relevant total target award percentage applicable to their position or positions during the relevant period.

(iv) Transfers and Leaves of Absence. In the event that during 2018, a Participant (A) transfers employment from Delta to a Delta subsidiary or Affiliate that does not participate in the MIP or (B) goes on any type of leave at any time during 2018, the Participant will have his Target MIP Award calculated, subject to Section 8(b)(v), based on his or her annual base salary (measured as of the date immediately prior to the date the transfer or leave is considered effective for purposes of the MIP) and the number of calendar months he or she was actively employed in a MIP-eligible position during 2018, multiplied by the relevant total target award percentage applicable to his or her MIP-eligible position.

(v) Military Leave. In the event that at any time during 2018 a Participant is on a Military Leave of Absence, his or her Annual Base Salary shall be equal to the aggregate annual base salary the Participant received from Delta during 2018 plus any amount of base salary such Participant would have received had he or she been actively employed by Delta in any corresponding MIP-eligible position during such leave. “Military Leave of Absence” means a Participant’s absence from his or her position of employment at any time during 2018 because of service in the uniformed services, as defined under the Uniformed Services Employment and Reemployment Rights Act of 1994, as amended (“USERRA”); provided, that a Participant must provide the Company appropriate evidence that his or her absence was due to service in the uniformed services and the period of such service in order to be considered to be on a Military Leave of Absence for purposes of the MIP. For purposes of the MIP, any Participant who is absent due to military service (according to Delta’s records) as of December 31, 2018 and has been on such leave for a cumulative period (during the period he or she has been employed by Delta) of five years or less, will be presumed to be on a Military Leave of Absence. Any Participant who is similarly absent due to military service (based on Delta’s records) and who has been on such leave for a period of more than five years will not be considered to be on a Military Leave of Absence until he or she provides appropriate evidence that he or she is entitled to an exception to the five-year limit on uniformed service as set forth in USERRA.



9. Treatment of Payments Under Benefit Plans or Programs. MIP payments, which for an Executive Officer Participant who receives MIP Restricted Stock means the amount of the payout to the Executive Officer Participant under the MIP had the payout been made in cash, will be considered as earnings under any benefit plan or program sponsored by Delta only to the extent such payments are included as earnings under the terms of the specific plan or program; provided, however, that any MIP payment made to an Executive Officer Participant in MIP Restricted Stock will be considered as earnings only for purposes of the Company’s restoration payment program, as in effect from time to time. If such payments are included, unless otherwise provided in such plan or program, Participants will be eligible to contribute amounts paid under the MIP into such plans in the same manner and to the same extent as their ordinary compensation and any amounts so contributed will be subject to any applicable Company contributions and/or matches. Notwithstanding anything to the contrary in this Section 9 and except as otherwise provided under the terms of any defined contribution plan sponsored by the Company, any MIP payment received in connection with a Termination of Employment shall not be considered earnings under any benefit plan or program sponsored by Delta.

10. Effective Date. The MIP will become effective as of January 1, 2018; provided however, if on or before the date the Committee adopts the MIP any employee who would otherwise have participated in the MIP is informed that his or her employment will be terminated by the Company without Cause, any severance such employee is entitled to receive will be calculated based on the 2017 Management Incentive Plan as in effect as of December 31, 2017.

11. Amendment. Except as otherwise expressly set forth in this Section and Section 14, the terms of Section 14 of the Performance Compensation Plan shall apply to any amendment or termination of the MIP. In addition, the terms applicable to any Participant will be subject in their entirety to the terms of any offer letter or other document to which the Participant has agreed. The terms of such offer letter or other document, if contrary to the terms of the MIP, shall govern the rights of the corresponding Participant.

12. Fractions. Any calculation under the MIP that results in a fractional amount will be rounded up to two decimal points.

13. Section 409A of the Code. Notwithstanding anything in the MIP to the contrary, any payments or benefits under the MIP are intended to be exempt from the applicable requirements of Section 409A of the Code and the regulations promulgated thereunder (together, “Section 409A”) and shall be limited, construed and interpreted in accordance with such intent; provided, however, to the extent that any amount paid hereunder in connection with a Termination of Employment constitutes deferred compensation under Section 409A and is paid to a “specified employee” as defined in Section 409A, the payment of such amount will be delayed for six months.

14. Clawback. Notwithstanding anything to the contrary in the MIP and subject to further amendment of this Section 14 to the extent required to be in compliance with any applicable law or regulation or Delta’s internal clawback policy, as it may be amended from time to time, if the Committee determines that a vice president or more senior officer Participant has engaged in fraud or misconduct that caused, in whole or in part, the need for a required restatement of Delta’s financial statements filed with the U.S. Securities and Exchange Commission, the Committee will review all incentive compensation awarded to or earned by such Participant, including, without limitation, any MIP Award, with respect to fiscal periods materially affected by the restatement and may recover from the Participant all such incentive compensation to the extent that the Committee deems appropriate after taking into account the relevant facts and circumstances. Any recoupment hereunder may be in addition to any other remedies that may be available to Delta under applicable law, including, disciplinary action up to

and including termination of employment.



## EXHIBIT A— DELTA CONNECTION GOALS:

Delta Connection’s Operational Performance will be based on the number of times during 2018 that the group of Delta Connection carriers meets or exceeds its monthly operational goals for completion factor and on-time arrival performance (the “Delta Connection Goals”). The monthly Delta Connection Goals are included on the following table:

<table><tr><td></td><td colspan="2">Completion Factor 2018 Goal</td><td colspan="2">On-Time Arrival Performance 2018 Goal</td></tr><tr><td>Month in 2018</td><td>Relative CF</td><td>Absolute CF</td><td>Relative A0</td><td>Absolute A0</td></tr><tr><td>January</td><td>1st</td><td>96.8%</td><td>1st</td><td>66.6%</td></tr><tr><td>February</td><td>1st</td><td>96.1%</td><td>1st</td><td>66.3%</td></tr><tr><td>March</td><td>1st</td><td>98.8%</td><td>1st</td><td>68.0%</td></tr><tr><td>April</td><td>1st</td><td>99.4%</td><td>1st</td><td>72.9%</td></tr><tr><td>May</td><td>1st</td><td>99.8%</td><td>1st</td><td>72.4%</td></tr><tr><td>June</td><td>1st</td><td>98.8%</td><td>1st</td><td>68.0%</td></tr><tr><td>July</td><td>1st</td><td>98.2%</td><td>1st</td><td>68.2%</td></tr><tr><td>August</td><td>1st</td><td>98.3%</td><td>1st</td><td>69.2%</td></tr><tr><td>September</td><td>1st</td><td>99.3%</td><td>1st</td><td>73.5%</td></tr><tr><td>October</td><td>1st</td><td>99.5%</td><td>1st</td><td>75.1%</td></tr><tr><td>November</td><td>1st</td><td>99.5%</td><td>1st</td><td>73.1%</td></tr><tr><td>December</td><td>1st</td><td>97.9%</td><td>1st</td><td>66.4%</td></tr><tr><td>Overall</td><td>1st</td><td>98.6%</td><td>1st</td><td>70.0%</td></tr></table>

The monthly goal in each performance category may be met by achieving either the specific numeric target or ranking (with a comparator group ranking of “1” being the best performance).

A. The primary source of reported metrics used to calculate performance will be each Delta Connection carrier’s data which flows into Delta’s data warehouse.

B. All domestic and international Delta Connection carrier system operations subject to capacity purchase agreements and/or revenue proration agreements will be included in the performance measures, including the operations of, Compass, ExpressJet, GoJet, Endeavor Air, Republic Airlines and SkyWest, but excluding any revenue proration operations with respect to which passenger reservations are not reflected on Delta’s reservations system (the “Delta Connection Program”). In the event that a carrier enters or leaves the Delta Connection Program, that carrier’s operations will be included or excluded from the performance measures as applicable.

C. The monthly calculation for completion factor will be as follows:

1. Add all Delta Connection scheduled system operations for the month.

2. Add all Delta Connection system completed flights for the month (including flights canceled by one carrier and covered by another via an extra section, which also includes flights changed to Delta aircraft).

3. Divide the result of C.2 by the result of C.1 for a combined Delta Connection system completion factor.

D. The monthly calculation for on-time performance will be as follows:

1. Add all Delta Connection completed system operations for the month.

2. Add all Delta Connection system on time operations for the month. On time operations are defined as the number of flights that arrive at the scheduled destination at the scheduled arrival time.

3. Divide the result of D.2 by the result of D.1 for a combined Delta Connection system on-time performance measure.

E. All calculations will be performed and validated by Delta Connection Operations.

F. The comparator group for the relative measure shall include the regional portfolios for Alaska Air Group, Inc., United Continental Holdings, Inc. and American Airlines Group, Inc. and the data is compiled by a third party selected by the Company.
