SIXTEENTH AMENDMENT TO CODE SHARE AND 

REVENUE SHARING AGREEMENT 

THIS SIXTEENTH AMENDMENT TO CODE SHARE AND REVENUE SHARING AGREEMENT (this “Sixteenth Amendment”) is made and
entered into as of January 26, 2015 (the “Effective Date”), by and between US AIRWAYS, INC., a Delaware corporation (“US Airways”) and MESA AIRLINES, INC., a Nevada corporation (“Mesa”). 

RECITALS: 

A.      US Airways and Mesa are parties to that certain Code Share and Revenue Sharing
Agreement, dated as of March 20, 2001 but effective as of February 1, 2001 (as amended, modified and supplemented, the “Code Share Agreement”). 

B.      The Code Share Agreement has previously been amended, including by the Tenth Amendment
to Code Share and Revenue Sharing Agreement, dated November 18, 2010 (the “Tenth Amendment”), the Eleventh Amendment to Codeshare and Revenue Sharing Agreement, dated July 1, 2012 (the “Eleventh Amendment”), the Twelfth
Amendment to Code Share and Revenue Sharing Agreement, dated February 13, 2013 (the “Twelfth Amendment”), the Thirteenth Amendment to Code Share and Revenue Sharing Agreement, dated December 24, 2013 (the “Thirteenth
Amendment”), the Fourteenth Amendment to Code Share and Revenue Sharing Agreement, dated April 10, 2014 (the “Fourteenth Amendment”), and the Fifteenth Amendment to Code Share and Revenue Sharing Agreement, dated
November 26, 2014 (the “Fifteenth Amendment”). 
 C.      All capitalized terms
used herein, but not otherwise defined herein, shall have the meanings given to such terms in the Code Share Agreement. It is the intent of the parties that this Sixteenth Amendment and the subject matter addressed herein is integral to the entirety
of the Code Share Agreement and is not severable therefrom. 
 D.      Mesa and US Airways
desire to amend the Code Share Agreement to add seven (7) new CRJ-900 aircraft to the Code Share Agreement and to make the other changes and agreements as set forth in this Sixteenth Amendment. 

AGREEMENT: 

NOW, THEREFORE, in consideration of the promises and covenants set forth herein, and for other valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, US Airways and Mesa agree as follows: 

1.      Termination of the Fifteenth Amendment. The parties hereby acknowledge and agree that the
Fifteenth Amendment shall be deemed terminated and of no further force and effect as of December 31, 2014. 

2.      Flight Services for American Airlines. In connection with the operational integration of US
Airways and American Airlines, Inc. (“American”) resulting from the merger between the parent company of US Airways, and a wholly-owned subsidiary of American’s parent company, American Airlines Group Inc. (formerly AMR Corporation),
Mesa acknowledges, agrees and 

  

					
	US Airways - Mesa 16th Amendment Final	  	1	  	














 
confirms that any Schedule provided to Mesa pursuant to Section 2.1 of the Code Share Agreement may include Flights operated for American under the “American Eagle” brand (the
“American Flights”). Mesa will perform the Flight Services in connection with such American Flights in accordance with the terms and conditions of the Code Share Agreement. Mesa will cooperate with US Airways and American to establish Mesa
as a carrier within the American systems as requested by US Airways and/or American from time to time. 

3.      Addition of CRJ-900 Aircraft. 

3.1      Sixteenth Amendment New Aircraft. Mesa will procure seven
(7) additional Bombardier CRJ-900 aircraft that have not previously entered into service prior to being Inducted (as defined below), as further described on Exhibit A hereto (the “Sixteenth
Amendment New Aircraft”), and will operate such Sixteenth Amendment New Aircraft pursuant to the terms of the Code Share Agreement, as amended hereby. The Sixteenth Amendment New Aircraft shall be considered Aircraft for all intents and
purposes of the Code Share Agreement, except as may be expressly provided otherwise in this Sixteenth Amendment. 

3.2      Term of Sixteenth Amendment New Aircraft. The Term of the Code
Share Agreement, as it relates to each Sixteenth Amendment New Aircraft, shall be extended for an additional ten (10) years from the induction date of each such Aircraft, as determined in accordance with Section 5.1 of this Sixteenth
Amendment (each such date, an “Induction Date”), such that the Code Share Agreement shall expire as to each Sixteenth Amendment New Aircraft on the tenth (10th) anniversary of each such
Aircraft’s Induction Date, unless terminated earlier as provided in the Code Share Agreement. 

3.3      Aircraft Procurement. No later than February 15, 2015, Mesa
shall demonstrate to US Airways’ reasonable satisfaction that Mesa will be able to execute definitive leases for, or otherwise procure, the Sixteenth Amendment New Aircraft (for example, by providing copies of executed leases, term sheets,
LOIs, or MOUs showing the estimated Delivery Date (as defined below) and term for the Sixteenth Amendment New Aircraft covered by such documents). Should Mesa fail to demonstrate to US Airways’ reasonable satisfaction that Mesa will procure and
deliver the Sixteenth Amendment New Aircraft as required hereby, at any time after February 15, 2015, US Airways may, at its sole discretion, terminate this Sixteenth Amendment without any further liability or obligation to Mesa whatsoever
unless otherwise provided in Section 16.6. Should US Airways elect not to terminate this Sixteenth Amendment, as provided in the previous sentence, and should Mesa be unable to lease, or otherwise procure, the Sixteenth Amendment New Aircraft
by March 15, 2015, Mesa may terminate this Sixteenth Amendment without any further liability or obligation to US Airways whatsoever unless otherwise provided in Section 16.6. 

4.      Configuration, Branding & Livery of Sixteenth Amendment New Aircraft. The
Sixteenth Amendment New Aircraft will be (i) painted in American Eagle livery, (ii) compliant with American Eagle brand interior and exterior specifications and branding requirements (“American Eagle Branding”), (iii) compliant
with the minimum specifications set forth in Exhibit B, (iv) 

  

					
	US Airways - Mesa 16th Amendment Final	  	2	  	














 
Wi-Fi enabled; the installation of any necessary equipment in connection therewith shall be at US Airway’s expense, and (v) delivered to Mesa on
the applicable Delivery Date and in the configuration specified in the “Sixteenth Amendment New Aircraft Delivery Schedule” set forth in Section 5.1 of this Sixteenth Amendment (the “Delivery Schedule”). US Airways and/or
American will provide the American Eagle Branding requirements to Mesa. Furthermore, American will provide such licenses and other documentation to Mesa regarding the American Eagle Branding as American may deem necessary in order to protect
American’s intellectual property rights (including without limitation the American Airlines and American Eagle trademarks and the American Eagle trade dress and livery). In the event that the Sixteenth Amendment New Aircraft are not Inducted,
as required by Section 5.1, the Late Delivery Charges (as defined below) and other terms and conditions applicable to the late delivery of the Sixteenth Amendment New Aircraft set forth in Section 5 below shall apply. US Airways shall pay
Mesa $[***] for each Sixteenth Amendment New Aircraft no later than twenty (20) days after such Aircraft is Inducted. Furthermore, US Airways will be allowed to inspect and approve each Sixteenth Amendment New Aircraft prior to its Induction
Date to ensure that the quality is in line with US Airways and American Airlines standards and the terms of this Sixteenth Amendment. 

5.      Aircraft Delivery and Induction for Sixteenth Amendment New Aircraft. 

5.1      Aircraft Delivery and Induction. The Sixteenth Amendment New
Aircraft shall be (i) painted, decorated and configured in accordance with Section 4, (ii) have adequate pilot and crew staffing, and (iii) otherwise be ready to operate in the US Airways network and/or the American system on the
applicable Induction Date (such Aircraft shall hereinafter be referred to as “Inducted”). In the event that a Sixteenth Amendment New Aircraft is not ready to be Inducted on the applicable Induction Date (each, a “Late
Aircraft”), Mesa shall immediately notify US Airways of such Late Aircraft by telephone and in writing by confirmed email (“Late Delivery Notice”). For each Late Aircraft, Mesa shall pay to US Airways late-delivery charges (the
“Late Delivery Charges”) in the amount of $[***] for each calendar day such Late Aircraft is Inducted after the applicable Induction Date (each a “Delay Day”). US Airways will provide an invoice for such Late Delivery Charges to
Mesa detailing the applicable Late Delivery Charges for each Late Aircraft and will offset such Late Delivery Charges against a future invoice from Mesa; provided that, in the event that Mesa incurs Late Delivery Charges in connection with any Late
Aircraft as provided herein and US Airways, at its option, decides to collect such Late Delivery Charges, US Airways shall adjust the Schedule accordingly such that Mesa’s Spare Aircraft will not be scheduled by US Airways to cover the Late
Aircraft. In lieu of collecting the Late Delivery Charges as provided in the previous sentence, US Airways may decide, at its option, to not adjust the Schedule and require Mesa to operate its Spare Aircraft to cover the Late Aircraft, provided that
in such event US Airways shall not collect Late Delivery Charges for such Late Aircraft. For clarification purposes only, US Airways will have the option as provided in the previous sentences for each Late Aircraft, if any. With respect to Late
Aircraft, after three hundred sixty five (365) cumulative Delay Days, US Airways may, at its option, elect to cancel the induction of such Late Aircraft. Late Delivery Charges shall constitute liquidated damages and not a penalty, and each
party agrees that such liquidated damages are a reasonable approximation of the actual damages but that the 

  

					
	US Airways - Mesa 16th Amendment Final	  	3	  	














 
amount of actual damages that would result from a Late Aircraft is difficult or impossible to calculate.

 Mesa shall provide US Airways with (i) at least 60 days prior written notice of the week
each of the Sixteenth Amendment New Aircraft will be delivered to Mesa and (ii) at least 30 days prior written notice (each, a “30-day Notice”) of the date on which each Sixteenth Amendment New
Aircraft will be delivered to Mesa (the delivery date set forth on each 30-day Notice shall hereinafter be referred to as a “Delivery Date”). The Induction Date for each Sixteenth Amendment New
Aircraft shall be the tenth day after the Delivery Date of each such Aircraft; provided, however, Mesa shall not be responsible for any delays associated with the installation of the wi-fi system that exceeds ninety-six (96 hours). 
 5.2      Force
Majeure. Notwithstanding the foregoing, performance by Mesa under this provision shall not be deemed to be in default and shall not give rise to the payment of the aforementioned Late Delivery Charges or any other penalties, costs, fees or
expenses of any kind where delays or defaults are directly due to manufacturer delays, war, insurrection, strikes, walk-outs, riots, floods, earthquakes, fires, casualties, acts of God, governmental restrictions imposed or mandated by governmental
entities after the date of this Sixteenth Amendment, enactment of conflicting state or federal laws or regulations, new or supplementary environmental regulations or litigation, materially adverse national or global economic conditions, or any other
matter beyond the reasonable control of Mesa; provided that failure to procure the Sixteenth Amendment New Aircraft or the materials and/or services necessary to Induct such Aircraft shall not be deemed to be matters beyond Mesa’s reasonable
control unless such failure is due to one of the specific events set forth above. 
 6.      Aircraft
Return Schedule. All Aircraft operated under the Code Share Agreement, including the Sixteenth Amendment New Aircraft, shall be ratably returned beginning January 1, 

  

					
	US Airways - Mesa 16th Amendment Final	  	4	  	














 
2021 in accordance with the applicable return schedule terms provided in the Twelfth and Thirteenth Amendments. The Aircraft will return at an approximate rate of three (3) aircraft per
month, provided that the Aircraft added by the Fourteenth Amendment (the “Fourteenth Amendment New Aircraft”) shall begin to be ratably returned beginning August 1, 2022 and the Sixteenth Amendment New Aircraft shall be ratably
returned beginning on the tenth (10th) anniversary of the Induction Date of the first Inducted Sixteenth Amendment New Aircraft, and provided further that the Term for each of the Sixteenth Amendment New Aircraft will be 10 years from the Induction
Date for each such Aircraft (unless terminated earlier or extended in accordance with the terms of the Code Share Agreement). Immediately after the return of each Aircraft as provided herein, Mesa shall remove any and all references to US
Airways’ trademarks, trade dress, livery, service marks and trade names and all references to the American Eagle Branding, as applicable, prior to any further use of such Aircraft. For purposes of this Section 6, “return” shall
mean that the respective Aircraft shall cease to be covered by the terms of the Code Share Agreement. 

7.      Rates. 

7.1      Rates. The rates applicable to the Original Aircraft (as such
term is defined in the Thirteenth Amendment), the Twelfth Amendment New Aircraft, the Aircraft added by the Thirteenth Amendment (the “Thirteenth Amendment New Aircraft”), the Fourteenth Amendment New Aircraft, and the Sixteenth Amendment
New Aircraft, upon their entry into service under the Code Share Agreement in accordance with the terms and conditions of this Sixteenth Amendment, are set forth in Exhibit C to this Sixteenth Amendment; provided that the Outstation
Maintenance rates stated in Exhibit C will go into effect for December 2014. For clarification purposes only, Exhibit C to this Sixteenth Amendment (including Notes 1 and 2) replaces Exhibit B attached to the Fourteenth
Amendment (including Notes 1 and 2) in its entirety. 

7.2      Escalation. For rate escalation adjustments beginning in
February 2014, the escalation rate will be based on the index specified in the Code Share Agreement, but capped at ***%. All the rates will be stated with up to two decimal points. Any future escalation will also be stated for up to two decimal
points. For clarification purposes only, any rates (including rates after escalation) shall only be calculated up to the second decimal point. 

7.3      Waiver of RON Maintenance Claims. Mesa agrees to waive any
claims for, and to forego any amounts in connection with, any disputed pass-through RON maintenance expense cost claimed by Mesa under the maintenance cost structure pursuant to the Code Share Agreement as amended up to and including the Fourteenth
Amendment, which have not been paid or reimbursed by US Airways as of the Effective Date. 

8.      Replacement of Code Share Agreement. Upon execution of this Sixteenth Amendment by both parties,
the parties shall, in good faith promptly negotiate and execute a new Capacity Purchase Agreement to replace the existing Code Share Agreement reflecting the foregoing terms and all applicable terms and conditions set forth in the Code Share
Agreement and its various amendments. The purpose of such new Capacity Purchase Agreement is to re-state and 

  

					
	US Airways - Mesa 16th Amendment Final	  	5	  	














 
organize the previous agreement and clean up dead language for ease of administration. The parties agree to work in good faith to have such new Capacity Purchase Agreement in place by
September 1, 2015. 
 9.      New Maintenance Base. 

9.1      ELP as new Maintenance Base. In connection with the closure of
the Maintenance Base at Charlotte (in accordance with the Notice of CLT Maintenance Base Closure, dated June 18, 2014), the parties agree that El Paso (ELP) shall be designated as a new Maintenance Base pursuant to Section 2.6.3 of the
Code Share Agreement (as amended by the Twelfth Amendment) replacing Charlotte (CLT). 

9.2      Rates. The payment rates for ELP, as stated under the header
“Maintenance Base Cost” in Exhibit C hereto, shall be the same as the current CLT rates, at $[***] per month; provided, however, it is agreed and understood that for periods during which ELP and CLT may both be Maintenance Bases
Mesa may only charge $[***] per month for both ELP and CLT collectively, but not $[***] per month for each of them. 

9.3      Payment. US Airways will reimburse Mesa for the reasonable out-of-pocket expenses in connection with the relocation of the maintenance base; provided that retention packages provided by Mesa in connection with the relocation will be
Mesa’s responsibility. Such reimbursement payments shall be made within 30 days of receipt by US Airways of an invoice from Mesa detailing the actual and reasonable costs incurred, and submission by Mesa of auditable documentation supporting
such actual and reasonable costs, to US Airways reasonable satisfaction. 
 10.      Performance Threshold
Changes due to LAX Transition. The new CD0 and CCF thresholds for operational performance pursuant to Section 9 of the Tenth Amendment (as amended), including cure rate, default rate, incentive level, penalty level 1 and level 2 to be
effective as of August 1, 2014 (the “Post LAX Transition Thresholds”) are set as follows (for convenience of the parties the thresholds as applicable immediately prior to the Effective Date are also provided): 

 

									
	 	  	 Pre LAX
Transition   Thresholds (i.e., effective   up to July 31, 2014)

 These thresholds will apply until new thresholds are established in accordance with the Code
Share Agreement. For purposes of setting revised operational performance thresholds in connection with potential future transitions, the parties agree to apply the same method as applied to set the LAX Transition Thresholds as provided in the Tenth
Amendment. In addition, notwithstanding anything herein to the contrary, as one-time accommodation, US Airways and Mesa, as applicable, agree to waive [***] of the dollar value of any penalties or bonuses, as
applicable, owed in this Section for the 3rd Quarter 2014 (July-September 2014), [***] of the dollar value of any penalties or bonuses owed in this Section for the 4th Quarter 2014 (October-December 2014), [***] of the dollar value of any penalties or bonuses owed in this Section for the 1st Quarter 2015
(January-March 2015), and [***] of the dollar value of any penalties or bonuses owed in this Section for the 2nd Quarter 2015 (April-June 2015) in connection with Mesa’s transition from
Charlotte, North Carolina and Los Angeles, California to Dallas, Texas. 
 Beginning with the
3rd Quarter 2015 (July-September 2015) the full dollar value of penalties shall begin to apply again subject to the following performance thresholds, which shall be unchanged until the end of the
Term: 
  

					
	Service Level	  	CD0	  	CCF
	  	Threshold	  	Threshold

	 Default (Bottom 5%)

[***]


 Effective as of January 1, 2015, the parties agree to (i) revise Section 8.2 of the Code Share
Agreement (as amended by Section 9(e) of the Tenth Amendment) to remove the early termination right and related provisions with regard to the CD0 default event and (ii) limit the CD0 portion of the Quarterly Performance Credit (as defined
in Section 9(a)(viii) of the Tenth Amendment) to a maximum amount of [***] ($[***]), i.e., the maximum amount owed by Mesa under this provision with respect to any CD0 performance credits per quarter will be [***] ($[***]). 

In addition, the parties agree that non-controllable damage cancellations extend through the entire
period the Aircraft is out of service. For each out of service day, Mesa shall receive a credit of two (2) cancelled flights per day for purposes of determining CD0 and CCF percentages above. 

11.      Spares. US Airways will schedule Mesa’s Aircraft to provide a minimum of one Spare Aircraft
per [***] active Aircraft operated at each hub, but in no event less than [***] Spare Aircraft per hub. For purposes of this Section 11, a “hub” shall mean an airport where Mesa operates a monthly average of [***] flights per day
under the Code Share Agreement. 

  

					
	US Airways - Mesa 16th Amendment Final	  	7	  	














 12.      Preferential Consideration of Furloughed
Pilots. US Airways, American and Mesa will enter into a letter agreement, regarding the terms and conditions pursuant to which Mesa will provide first consideration in Mesa’s application and screening process to mainline pilots on furlough
from either the American or US Airways (East or West) pilots seniority lists, if (i) Mesa is hiring pilots, and (ii) there are mainline pilots on furlough from American or US Airways. 

13.      Quality of Service and Aircraft Condition. 

13.1      Conflict. In the event of a conflict between the provisions of
(i) this Section 13 and/or Exhibit D or Exhibit F hereto and (ii) the provisions of the Code Share Agreement, the provisions of this Section 13 and/or Exhibit D or Exhibit F shall govern as to their
subject matter. 
 13.2      Procedures and Performance Standards. At
all times, Mesa shall provide Flight Services to US Airways or American, as applicable in accordance with procedures and performance standards approved by US Airways from time to time in its sole discretion and provided in writing to Mesa, including
but not limited to those certain Standards of Service set forth in Exhibit D hereto (“Service Standards”). The Service Standards may be amended or changed by US Airways from time to time upon thirty (30) days’ prior notice
to Mesa; provided that sixty (60) days’ notice shall be given by US Airways to the extent any such amendment or change may reasonably be expected to result in new or additional training. If Service Standards are materially changed
or altered and such changes or alterations materially increase Mesa’s costs (i.e., an amount of more than [***] ($[***]) per year), US Airways shall reimburse Mesa for the actual incremental costs associated therewith, subject to Mesa providing
sufficient documentation for such cost reasonably acceptable to US Airways. Mesa shall be responsible for all crew and other employee conduct, appearance and training policies (as set forth on Exhibit F), aircraft cleaning (including the
timing thereof), standards and adequate staffing levels in order to comply with such procedures and meet such standards, including without limitation in respect of customer complaint response and any handling of irregular operations, all of which
shall be handled in a professional, businesslike and courteous manner. 

13.3      In-Flight Services.
Mesa shall comply with the catering requirements set forth on Exhibit D hereto. Mesa shall also coordinate all in-flight services relating to the Flight Services with the
in-flight services department of US Airways or any person designated by US Airways to ensure consistency and quality of Mesa’s in-flight service, including non-safety related functions such as in-flight marketing announcements, meal and beverage presentation and delivery, and provisioning and usage of passenger amenity kits. Mesa
shall sell beer, wine, liquor and any other alcoholic beverages on Flights. Mesa agrees that such in-flight sales shall be conducted as directed by US Airways or American, as applicable, from time to time.
Mesa shall implement any suggestions made by US Airways’ or American’s in-flight services department, as applicable. All revenues collected by Mesa for such
in-flight services on the Aircraft shall be promptly remitted or provided to US Airways. Mesa must provide notice to US Airways of any threatened catering-related fines or penalties that could result in a
liability to US Airways or American within ten (10) days of receipt of such notification and allow for the 

  

					
	US Airways - Mesa 16th Amendment Final	  	8	  	














 
involvement of US Airways or American, as applicable, in the resolution process of such issue so that the parties can work to minimize any fines to US Airways or American, as applicable. 

13.4      Mesa’s Representative Uniforms. Mesa shall require all of
its respective personnel and any of its respective agents providing Flight Services in job classifications requiring direct public contact to wear uniforms and accessories furnished by Mesa that are of colors and styles approved by US Airways from
time to time. Mesa shall not alter or change such uniforms and accessories without the prior written consent of US Airways. If, after the date hereof, US Airways determines, in its sole discretion, that such uniforms and accessories should be
materially altered or changed, then US Airways shall provide Mesa with notice of such alterations or changes. In the event that US Airways decides to implement such alterations or changes, Mesa shall implement such alterations or changes at US
Airways’ cost for Mesa’s then current employees. 
 13.5      No
Reimbursement of Fines. US Airways shall not be required to incur any cost or make any payment to the extent such cost or payment is attributable to any costs, expenses or losses (including fines, penalties and any costs and expenses associated
with any related investigation or defense) incurred by Mesa as a result of any violation by Mesa of any law, statute, judgment, decree, order, rule or regulation of any governmental authority. US Airways shall be liable for all costs, expenses and
losses (including fines, penalties and any costs and expenses associated with any related investigation or defense) incurred by Mesa as a result of any violation by US Airways, American or their respective agents, or by Mesa to the extent performed
at the direction of US Airways or American, of any law, statute, judgment, decree, order, rule or regulation of any governmental authority. Mesa must provide notice to US Airways of any notification that could result in a liability to US Airways or
American within ten (10) days of receipt of such notification and allow for the involvement of US Airways or American, as applicable, in the resolution process of such issue so that the parties can work to minimize any fines to US Airways or
American. 
 13.6      Right to Audit Service and Aircraft Condition.
US Airways has the right, in its sole discretion, to audit Mesa’s service (each such audit a “Service Audit”) and aircraft condition (each such audit an “Aircraft Condition Audit”) to ensure it meets the Service Standards
and Aircraft Condition Standards and actions required as above and in Exhibit D or other Service Audit and/or Aircraft Condition Audit standards that may be developed by US Airways or American from time to time. US Airways will review the
Service Audit and Aircraft Condition Audit program for a period to be determined in its discretion in order to determine the appropriate pass and fail rates for such audits. An Inflight Service sample survey is described in Schedule 1 to Exhibit
D, and an Aircraft Condition sample survey is described in Schedule 2 to Exhibit D, provided that such samples can be changed at any time in US Airways’ sole discretion. If Aircraft Condition Standards are materially changed or
altered and such changes or alterations materially increase Mesa’s costs (i.e., an amount of more than [***] ($[***]) per year), US Airways shall reimburse Mesa for the actual incremental costs associated therewith, subject to Mesa providing
sufficient documentation for such cost reasonably acceptable to US Airways. If an Aircraft fails (i) a Service Audit, Mesa shall pay $[***] per failed audit, 

  

					
	US Airways - Mesa 16th Amendment Final	  	9	  	














 
and (ii) an Aircraft Condition Audit and such failure continues for seven (7) calendar days after Mesa’s receipt of written notice from US Airways, Mesa shall pay $[***] per day
for any failure to remedy the failure noted in the Aircraft Condition Audit within the 7-day cure period; provided, however, that such remedies as provided under (i) and (ii) above shall not become
effective until nine (9) months after Mesa has received written notice from US Airways that the audit program as described in this Section 13.6 has been implemented, and provided further that during such
9-month period the parties shall meet and confer in good faith as to review initial findings and determine the appropriate pass and fail levels for each audit, subject to US Airways setting such pass and fail
levels in the event that the parties are unable to agree on appropriate pass and fail levels. 

14.      Fuel Efficiency Program. Section 10 of the Twelfth Amendment is deleted in its entirety and
replaced by the following: 
 “Fuel Management. Mesa shall continue to fully participate in US Airways’
fuel management program (Fuel Efficiency Program) and will work to actively manage fuel consumption and minimize over all fuel expense. Mesa shall promptly adopt and adhere to the fuel efficiency program as described on Exhibit E to the
Sixteenth Amendment, as long as Mesa’s adoption or adherence to such fuel efficiency program does not impact the safety of Flight Services under FAA operational specifications, or other regulatory constraints, or the airworthiness of the
Aircraft or materially increase Mesa’s costs in any way.” 
 15.      Withdrawal of Aircraft in
lieu of Termination. In the event that US Airways has the right to terminate the Code Share Agreement for any reason (including, without limitation, for any default by Mesa under the Code Share Agreement), US Airways shall have the right, in its
sole discretion, instead of exercising any such termination right, to withdraw from the coverage of the Code Share Agreement up to fourteen (14) aircraft (i.e., any number between one and fourteen (14) aircraft), it being understood that
(i) the fourteen (14) aircraft may be withdrawn in increments of any number of aircraft, provided that not more than fourteen (14) aircraft total may be withdrawn pursuant to this Section 15 over the remainder of the Term, and
(ii) after such withdrawal any such withdrawn aircraft shall no longer be used to provide Flight Services under the Code Share Agreement and it being understood further that any payments by US Airways to Mesa pursuant to the Code Share
Agreement shall be reduced accordingly. US Airways shall provide written notice to Mesa stating the effective date on which each such withdrawn aircraft will be withdrawn from the coverage of the Code Share Agreement (the “Withdrawal
Notice”); provided that (i) Mesa, in its sole discretion, shall select the aircraft to be withdrawn on each withdrawal date stated in the Withdrawal Notice, except that in the event any default giving rise to a withdrawal right by US
Airways is associated with any one or more particular covered aircraft, US Airways has the right, in its discretion, to have such aircraft withdrawn from coverage pursuant to this Section 15; (ii) the Withdrawal Notice shall be irrevocable by
US Airways once received by Mesa; (iii) the withdrawal rights pursuant to this Section 15 may only be exercised by US Airways within ninety (90) days of the date on which the respective termination right is triggered (it being
understood, that there may be multiple Withdrawal Notices, and it being understood further that such ninety (90) day period runs separately for each termination right US Airways may have whether concurrently or consecutively); (iv) the earliest
date on which an aircraft may be withdrawn pursuant to a Withdrawal Notice shall be thirty (30) 

  

					
	US Airways - Mesa 16th Amendment Final	  	10	  	














 
days from the date of such Withdrawal Notice; and (v) US Airways may not withdraw more than four (4) aircraft during any given calendar month. 

16.    Miscellaneous. 

16.1      Except as set forth in this Sixteenth Amendment, all of the terms and
conditions of the Code Share Agreement shall remain in full force and effect and be applicable to this Sixteenth Amendment. 

16.2      This Sixteenth Amendment may be executed in counterparts, all of which
when taken together shall be one and the same document. 
 16.3      This

	US Airways - Mesa 16th Amendment Final	  	17	  	














 Note 1 – As of the Execution Date, Pilot and Flight Attendant cost will be set at the
rates set forth above in this Exhibit C. Rate for Mesa’s pilots may be adjusted once during the remainder of the term of the Code Share Agreement to reflect an increase to the pay scale for the pilots of no more than [***] ([***]) any
time after January 16, 2015 to account for any new or renegotiated collective bargaining agreement, provided that such adjusted rate shall not be billed to US Airways until after such adjusted rate is effective and paid to the Mesa’s
pilots. 
 Note 2 – In addition to the Aircraft (as defined below), Mesa may, subject to the terms and conditions of this Note 2, in
its discretion and at its sole expense, arrange for and utilize substitute CRJ-900 aircraft or CRJ-200 aircraft in American Eagle/US Airways Express livery (as
applicable based on the terms of the Code Share Agreement) or neutral livery to provide the Flight Services under this Code Share Agreement during those periods, but only during those periods, when any of the Original Aircraft, the Twelfth Amendment
New Aircraft, the Thirteenth Amendment New Aircraft, the Fourteenth Amendment New Aircraft or the Sixteenth Amendment New Aircraft (collectively, “Aircraft”) may be out of service due to unforeseen and irregular maintenance requirements;
provided that (i) each substitute CRJ-200 aircraft shall be subject to compliance with flight interior and exterior standards and shall be approved by US Airways in writing before being used as a
substitute aircraft pursuant to this Note 2, and (ii) Mesa may only utilize regional jet aircraft other than CRJ-900 or CRJ-200 aircraft to the extent that US
Airways has permitted such use in advance in writing. For clarification purposes only, Mesa may operate such a substitute aircraft in US Airways Express or neutral livery in lieu of an Aircraft in US Airways Express livery and Mesa may operate such
a substitute aircraft in American Eagle or neutral livery in lieu of an Aircraft in American Eagle livery, but may not operate a substitute aircraft in US Airways Express livery in lieu of an Aircraft in American Eagle livery or a substitute
aircraft in American Eagle livery in lieu of an Aircraft in US Airways Express livery, without the prior written consent of US Airways. 
  

	 	a)	 Notwithstanding anything in the Code Share Agreement to the contrary, and assuming approval is granted, usage
of substitute CRJ-200 aircraft shall be paid as follows: 


  

	 	(1)	 Rates paid for operation of this aircraft will be $[***] per block hour and $[***] per departure plus any fuel
costs associated with these substitute operations. Such rate shall be reduced by [***] after the 24th Flight of such aircraft in a calendar month, reduced by [***] after the 32nd Flight of the calendar month, and [***] after the 40th Flight of the calendar month. Any CRJ-200 Flights
operated as a result of Aircraft Damage caused by US Airways shall be excluded from the calculation and not subject to reductions pursuant to this paragraph. 



 

	 	(2)	 In addition, the amount paid to Mesa will be further adjusted by any interrupted trip or passenger
inconvenience costs to include, without limitation, such things as meals and hotels for displaced passengers, as well as an amount of $[***] per passenger downgraded from first class to coach class (excluding
CRJ-200 flights operated because of Aircraft Damage caused by US Airways). 


  

	 	b)	 If a substitute aircraft shall be utilized for more than two (2) consecutive days, Mesa and US Airways
shall mutually agree upon the route that shall be covered by the substitute aircraft. 



  

					
	US Airways - Mesa 16th Amendment Final	  	18	  	















	 	c)	 For clarification purposes only, if a substitute aircraft is used in accordance with the terms hereof, the
applicable provisions of the Code Share Agreement shall also apply to the Flight Services operated by such substitute aircraft, including, without limitation, if the respective Flight is not operated for any reason. 



 

	 	d)	 The provisions of this Note 2 replace Section 9(d)(ii) of the Tenth Amendment in its entirety.

 EXHIBIT D 

STANDARDS OF SERVICE 
 These
“Standards of Service” are meant to provide an overview for Mesa of the service expectations established by US Airways and American for in-flight services on Flights. The Standards of Service
outlined herein are not all-inclusive and may be changed from time to time by US Airways in its sole discretion. 

I. In-Flight Service Product and Delivery. Mesa shall achieve at least the comparable
quality of airline service as provided by US Airways and American, as applicable. Mesa shall coordinate with US Airways’ In-flight Services Department, or any similar department of any affiliate of US
Airways as designated by US Airways, to ensure consistency and quality of Mesa’s in-flight service product, including non-safety related functions such as in-flight marketing announcements, meal and beverage presentation and delivery and provisioning and usage of passenger amenity kits. Mesa shall implement suggestions made by US Airways’ or its affiliate’s In-flight Services Department. Mesa shall coordinate with US Airways to ensure consistency with US Airways’ product delivery, including US Airways or American-logo, as applicable, napkins, stir rods and cups.
Wherever possible, snack and beverage items should be consistent with the products served by US Airways and American, as applicable. Each Aircraft shall be supplied by US Airways or American, as applicable, with an adequate supply of US
Airways’ or American’s, as applicable, in-flight publications. Mesa must place these in-flight publications in the designated seat pocket of each seat. Unless
otherwise consented to by US Airways or American, as applicable, US Airways’ or American’s in-flight publications are the only magazines authorized in such seat pockets. 

II. Uniforms. Mesa’s flight attendants on Flights shall wear uniforms as required under Section 13.4 of the Sixteenth
Amendment. Mesa’s employees in such uniforms, whether on or off duty, are not permitted to drink intoxicating beverages, give the appearance of being intoxicated or visit any establishment whose primary purpose is to dispense liquor (including
bars, saloons, cocktail lounges and liquor stores). As used herein, “uniform” refers to any uniform apparel bearing the US Airways or American brand or insignia, or which can be in any way identified with US Airways or American or one of
their affiliates. Because the actions and appearance of employees influence, to a considerable extent, the public’s opinion of the US Airways and American brands, uniformed employees must be mindful of this and conduct themselves accordingly.

 III. In-Flight Announcements. While Mesa shall provide basic announcements, US
Airways may request that Mesa make promotional announcements on behalf of US Airways and/or American from time to time and Mesa shall honor and execute any such request. In all on-board announcements on
Flights, only the names “US Airways”, “US Airways Express”, “American Airlines” or “American Eagle” may be included and Mesa’s names shall not be included unless otherwise consented to by US Airways. 


  

					
	US Airways - Mesa 16th Amendment Final	  	20	  	














 IV. Catering. US Airways or American, as applicable, shall provide, or arrange
for another person to provide, all catering products and catering services for Flights, and, as directed by US Airways or American, Mesa shall serve the catering products on all such flights in accordance with procedures and standards approved by US
Airways or American, as applicable, in their sole discretion. 
 V. Failure to Meet Standards of Service. In the event that
Mesa fails to meet the Standards of Service as set forth in this Exhibit D, in addition to the remedies provided in Section 13.6 of this Sixteenth Amendment for a Service Audit failure, US Airways may give notice to Mesa of such failure
and the parties’ representatives shall meet within fifteen (15) days to discuss such failure in good faith. At such meeting, Mesa shall submit to US Airways a corrective action plan that Mesa reasonably believes will cure such failure to
meet the Standards of Service within thirty (30) days and provide adequate assurance to US Airways that such Standards of Service will be complied with for the foreseeable future.
