AIRCRAFT PURCHASE AGREEMENT, dated as of September 27, 2022 (this “Agreement”), among Mesa Airlines, Inc., a Nevada corporation having its principal office at 410 North 44th Street, Suite 700, Phoenix, Arizona 85008 (“Seller”), United Airlines, Inc., a Delaware corporation having its principal office at 233 South Wacker Drive, Chicago, Illinois 60606 (“Purchaser”), and, for certain provisions set forth in this Agreement, Mesa Air Group, Inc., a Nevada corporation having its principal office at 410 North 44th Street, Suite 700, Phoenix, Arizona 85008 (“Mesa Air Group” and together with Seller, “Mesa Parties,” and each individually, “Mesa Party”). Purchaser, Mesa Air Group and Seller may be referred to herein individually as a “Party” and, collectively, as the “Parties.”

WHEREAS, Seller desires to sell, and Purchaser desires to purchase, such Aircraft;

WHEREAS, the Parties now desire to enter into a definitive agreement pursuant to which Seller will sell to Purchaser, and Purchaser will purchase from Seller, the Aircraft; and

WHEREAS, concurrently with the Closing Date with respect to each Aircraft under this Agreement, Seller and Purchaser desire to enter into a lease assignment and assumption agreement with respect to each such Aircraft effective as of such Closing Date pursuant to which Seller will assign to Purchaser the Lease related thereto (each such agreement, a “Lease Assignment” and together with this Agreement, the “Definitive Documentation”);

NOW, THEREFORE, for good and valuable consideration, the receipt, validity, and sufficiency of which are hereby acknowledged, the Parties hereto agree as follows:

Section 1.1. Definitions. For all purposes of this Agreement, capitalized terms used herein and not otherwise defined have the meanings given to them in Schedule 1 attached hereto.

Section 1.2. Interpretation. All references in this Agreement to Exhibits, Appendices, Schedules, Articles, Sections, paragraphs, subsections, and other subdivisions refer to the corresponding Exhibits, Appendices, Schedules, Articles, Sections, paragraphs, subsections, and other subdivisions of or to this Agreement unless expressly provided otherwise. Titles appearing at the beginning of any Articles, Sections, paragraphs, subsections, or other subdivisions of this Agreement are for convenience only, do not constitute any part of this Agreement, and shall be disregarded in construing the language hereof. The words “this Agreement,” “herein,” “hereby,” “hereunder,” and “hereof,” and words of similar import, refer to this Agreement as a whole and not to any particular Article, Section, subsection, or other subdivision unless expressly so limited. The words “this Article,” “this Section,” and “this subsection,” and words of similar import, refer only to the Article, Section, or subsection hereof in which such words occur. The word “including” (in its various forms) means “including without limitation”. All references to “$” or “dollars” shall be deemed references to United States Dollars. Pronouns in masculine, feminine, or neuter genders

shall be construed to state and include any other gender, and words, terms, and titles (including terms defined herein) in the singular form shall be construed to include the plural and vice versa, unless the context otherwise requires. Appendices, Schedules, and Exhibits referred to herein are attached hereto. Except as otherwise provided in this Agreement, any reference herein to any law shall be construed as referring to such law as amended, modified, codified, or reenacted, in whole or in part, and in effect from time to time, and references to particular provisions of a law include a reference to the corresponding provisions of any prior or succeeding law, and any reference herein to a document includes that document as amended from time to time in accordance with its terms, and any document entered into in substitution or replacement therefor. Any reference to an amendment includes a supplement, novation, or re-enactment, and “amended” is to be construed accordingly. The word “extent” in the phrase “to the extent” means the degree to which a subject or other theory extends, and such phrase shall not simply mean “if”. Whenever this Agreement refers to a number of days, such number shall refer to calendar days unless Business Days are specified, and Business Days refer to days that are Business Days in each of Chicago, Illinois and New York City, New York. Whenever any action must be taken hereunder on or by a day that is not a Business Day, then such action may be validly taken on or by the next day that is a Business Day. Time shall be of the essence in this Agreement. Any reference to any federal, state, local, or foreign law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context shall otherwise require. Reference herein to “federal” shall be construed as referring to U.S. federal.

Section 2.1. Sale and Purchase of Aircraft; Assignment of Lease. With respect to each Aircraft, Seller agrees to sell, and Purchaser agrees to buy, such Aircraft in each case upon and subject to the terms and conditions of this Agreement. The aggregate consideration payable with respect to each Aircraft on the Closing Date of such Aircraft will be the Purchase Price; provided that, the payment of the applicable Purchase Price or portion thereof shall be in accordance with the applicable provisions of this Agreement, including ARTICLE III and ARTICLE IX. In addition, on the Closing Date with respect to each Aircraft:

(a)Seller shall, by execution and delivery of a Bill of Sale, sell to Purchaser outright and unconditionally good and marketable title in and to the Aircraft, free and clear of all Liens except Permitted Liens.

(b)Concurrently with Seller’s delivery to Purchaser of an executed Bill of Sale, Purchaser shall accept delivery of the Aircraft, and Purchaser shall execute and deliver an Aircraft Acceptance Certificate in respect of such Aircraft.

(c)With respect to each Aircraft, concurrently with the Closing of the sale and purchase of such Aircraft under this Agreement, Seller, Purchaser and [***] will consummate a Lease Assignment with respect to each such Aircraft, among other things, pursuant to which the Purchaser will be substituted as the “Lessor” under the Lease applicable to such Aircraft.

(a)The aggregate consideration payable by Purchaser to Seller at the Closing for each Aircraft shall be equal to [***] The Base Purchase Price for a particular Aircraft [***] is referred to in this Agreement as the “Purchase Price”.

(b)If the Closing Date in respect of an Aircraft occurs after [***] (the “Economic Closing Date [***]

(a)Within [***] following the date on which both Parties have executed this Agreement, [***] for each Aircraft with respect to which Closing has occurred prior to the end of such [***] period. With respect to each Aircraft, such Deposit shall be refundable in whole or in part as set forth below in this Section 3.2; provided that, for all purposes of this Agreement, a reference to the Deposit with respect to an Aircraft (including any associated terms and conditions with respect to the return of the Deposit with respect to a particular Aircraft) shall be deemed to refer only to the $[***] portion of the Deposit applicable to such particular Aircraft [***]

(c)Each of the following shall constitute a “Deposit Return Event” with respect to an Aircraft (it being understood that a Deposit Return Notice may, but shall not be required to, apply to more than one Aircraft):

(v)in the event that a bankruptcy case or bankruptcy proceeding is commenced by or against the [***] Seller, or Mesa Air Group; or

(vi)in the event that Purchaser has terminated this Agreement with respect to such Aircraft pursuant to Section 4.5.

(d)If a valid written notice of termination of this Agreement with respect to any Aircraft is submitted pursuant to Section 13.1(c), then, in addition to any rights or remedies available to Purchaser at Law or in equity (subject to any limitations on such rights and remedies as are expressly set out in this Agreement), [***]

Section 4.1. Purchaser’s Right to Inspection. Prior to the Closing Date of each Aircraft, Seller shall, subject to the proviso in Section 4.3, make the Aircraft available to allow Purchaser to inspect such Aircraft, including the Data, in order to confirm, without limitation, the completeness and airworthiness of the Aircraft, the accuracy of the representations and warranties of the Mesa Parties set forth in Section 10.1 with respect to the Aircraft, and to review the compliance by Seller with its covenants and agreements hereunder with respect to the Aircraft. The provisions below in this ARTICLE IV shall not, subject to the proviso in Section 4.3, limit the generality of the foregoing sentence.

Section 4.2. Data. Prior to the Closing Date of each Aircraft, Purchaser shall be entitled to inspect the Data for such Aircraft (the “Data Inspection”), and, in furtherance of the same, Seller shall (i) make available to Purchaser all Data for such aircraft that is in Seller’s possession and (ii) use commercially reasonable efforts to cause the [***] to make available to Purchaser any and all Data for such Aircraft that are both (x) not in Seller’s possession and (y) reasonably available to the [***]. From and after the Closing with respect to each Aircraft and until the [***]thereafter, Seller shall use commercially reasonable efforts to assist Purchaser with Purchaser’s reasonable requests regarding the Data for the applicable Aircraft or the contents thereof, including providing all maintenance records in Seller’s possession as to such Aircraft and any components thereof (in each case whether or not constituting Data for such Aircraft) and seeking to obtain from the [***] records that are not in Seller’s possession.

Section 4.3. Physical Inspection. Prior to the Closing Date of each Aircraft, Purchaser shall have the right to conduct an inspection of such Aircraft, limited to a “walk around” inspection level of access where no panels requiring tools may be opened (the “Physical Inspection” and together with “Data Inspection,” the “Inspection”). To facilitate such inspection by Purchaser, Seller shall, for each Aircraft, arrange such Physical Inspection by Purchaser for each Aircraft at the applicable Delivery Location, and, as to the Aircraft other than the Tranche 1 Aircraft, Seller shall use commercially reasonable efforts to cause [***] to make each such Aircraft available for Physical Inspection and its related Data available for Data Inspection, in each case, no later than [***]; provided that, Seller’s obligations to arrange such Physical Inspection and Data Inspection is (i) acknowledged by the Parties to be subject to the cooperation of [***] and the Purchaser and that both Seller and Purchaser shall use commercially reasonable efforts to procure such cooperation from [***] and (ii) is subject to Section 4.4.

Section 4.4. Access to Data and Aircraft. Seller shall provide access to the Aircraft (subject to the proviso in Section 4.3) for Purchaser’s Inspection as and when available to avoid any unreasonable disruption to the [***] service operations for Purchaser (the existence of any such disruption to be reasonably determined by Purchaser) and, with Purchaser’s prior written consent, may occur during night stops or short flight operational turnarounds. Purchaser agrees to make its applicable representatives available for such Inspection as and when reasonably required to accommodate the schedule of the Aircraft and the [***]. Any such Inspection shall be subject to the applicable terms and conditions of this Agreement and the applicable Lease. The Parties shall cooperate reasonably to consider extensions to the timeframe for completing the Inspection for an Aircraft or its related Data if the availability of such Aircraft, components thereof, or the Data is

adversely impacted by circumstances beyond the Parties’ or the [***] reasonable control or by the [***] lack of cooperation to make the same reasonably available. With respect to each Aircraft, including Data, Purchaser shall use commercially reasonable efforts to cause such Inspection to be completed by the later of (i) the date falling [***] following the date Seller has caused [***] to provide access to all Data for such Aircraft and (ii) the [***] following the date on which Purchaser has been furnished actual physical access to the Aircraft by either Seller or the [***]

Section 4.5. Post-Inspection. With respect to each Aircraft inspected by Purchaser in accordance with the foregoing provisions of this ARTICLE IV, Purchaser shall notify Seller in writing no later than [***] following completion of the Inspection of such Aircraft of either (a) Purchaser’s satisfaction with such Inspection or (b) any concerns arising from such Inspection which may prevent Purchaser from accepting such Aircraft. If no such notification is received by Seller within such time period or, if Purchaser has been given a reasonable opportunity to inspect such Aircraft in accordance with the foregoing provisions of this Article IV and Purchaser does not complete the Inspection within the time frame set out in the last sentence of Section 4.4 (subject to any extension thereof agreed by Purchaser and Seller in writing), then Purchaser shall be deemed to have completed the Inspection in respect of such Aircraft to Purchaser’s satisfaction. If such notification is received by Seller within such time period and Purchaser notes any material concerns in such notification, then Seller and Purchaser shall discuss in good faith the resolution of any such concerns. If Seller does not resolve the material concerns raised by Purchaser in such notification in a manner reasonably acceptable to Purchaser on or prior to the [***] following Purchaser’s delivery of such notification, then Purchaser may terminate this Agreement in respect of such Aircraft, and the applicable Deposit refund provisions of Section 3.2 shall apply. Notwithstanding the foregoing provisions of this Section 4.5, Purchaser acknowledges and agrees that the Unserviceable Engines are in unserviceable or runout condition (as applicable) and that (i) such condition shall not be the basis upon which Purchaser may note a “material concern” or decline to accept the Unserviceable Engines and (ii) subject to and without limiting Section 5.2, Seller shall not be required to take any remedial actions with respect to the Unserviceable Engines.

Section 5.1. Condition. Each Aircraft shall be delivered by Seller and accepted by Purchaser at the Closing for such Aircraft in the condition and subject to the disclaimers and agreements set forth in Section 16.1.

Section 5.2. Delivery Location of Aircraft; Location and Placement of In-Scope Engines at Closing.

(a)With respect to each Aircraft, Seller shall cause such Aircraft to be located in Kingman, Arizona at the Closing for such Aircraft at an address to be designated by Purchaser by written notice delivered to Seller no later than [***] prior to such Closing (the “Delivery Location”) or, if the Seller notifies Purchaser that delivery to such location is not possible, then at such other location designated by Purchaser and such other location, if any, shall instead be the “Delivery Location”; provided, however, that (x) with respect to the STL Engines, the Delivery Location shall instead be in St. Louis, Missouri at an address to be designated by Purchaser by written notice delivered to Seller no later than [***] prior to the Closing for the Aircraft applicable to such STL Engines, and (y) with respect to the GE Engine, subject to Section 5.2(d), the Delivery Location shall instead be in Houston, Texas (with further delivery thereafter to IGM as provided in Section 5.2(d)). Seller’s obligation to cause each Aircraft (including its associated In-Scope Engines) to be located at the applicable Delivery Location in accordance with this Section 5.2 is acknowledged by the Parties to be subject to the cooperation of [***] and that Seller and Purchaser shall each use commercially reasonable efforts to procure such cooperation from [***] and to cause [***] to position each Aircraft (including its associated In-Scope Engines) at such Delivery Location; provided that, such positioning does not cause unreasonable disruption to [***]operations thereof, as reasonably determined by Purchaser.

(c)With respect to each Aircraft, if, despite the use of commercially reasonable efforts required by Section 5.2(b)(ii), Seller is unable to cause [***] then (i) without limitation of any provision of ARTICLE VI, ARTICLE VII, ARTICLE VIII and ARTICLE IX (other than any requirements thereof that are not satisfied as a consequence [***] the Parties shall proceed to the Closing of such Aircraft, (ii) Seller (and each of Seller’s agents, contractors, and representatives) is hereby authorized by Purchaser to and shall[***], but in no event later than [***] following the Closing of such Aircraft, and (iii) Seller shall indemnify and hold harmless the Purchaser Indemnified Parties, and each of them, from and against any and all claims not covered by available insurance incurred or suffered by, asserted against, charged to, or recoverable from any of the Purchaser Indemnified Parties and which arise to any extent out of or are in any manner connected [***] in each case whether or not caused by a Mesa Party’s breach of this Agreement but expressly excluding any claims caused by the gross negligence or willful misconduct of any Purchaser Indemnified Party.

(d)With respect to the GE Engine, the Parties acknowledge and agree that the HPT is currently, and is expected to be at the Closing for the Aircraft associated with such GE Engine,

under repair at GE Engine Services Strother, 7577 4th Avenue, Strother Field Industrial Park, Arkansas City, Kansas 67005 (the “GE Facility”) pursuant to repair order number 322012381. Notwithstanding the foregoing, Purchaser shall take title to the entire GE Engine (including the HPT associated therewith) at the Closing for the Aircraft associated with such GE Engine. As soon as practicable following the Closing with respect to such Aircraft, but in no event more than [***] thereafter or such later date that is [***] after the date on which repair of the HPT has been completed by GE Facility and Seller has received possession thereof, Seller (and each of Seller’s agents, contractors and representatives) is hereby authorized by Purchaser to and shall, [***] cause the HPT to be reinstalled in the GE Engine and to thereafter promptly deliver the same to IGM. Seller shall notify the GE Facility and any and all applicable vendors that Purchaser has taken title to such HPT as of such Closing. Seller shall indemnify and hold harmless the Purchaser Indemnified Parties, and each of them, from and against any and all claims not covered by available insurance incurred or suffered by, asserted against, charged to, or recoverable from any of the Purchaser Indemnified Parties and which arise to any extent out of or are in any manner connected with Seller’s obligations under this Section 5.2(d) but expressly excluding any claims caused by the gross negligence or willful misconduct of any Purchaser Indemnified Party.

(a)With respect to the Tranche 1 Aircraft, the Closing shall occur by teleconference and electronic exchange of documents on the [***] following full satisfaction or waiver of all of the conditions precedent set forth in ARTICLE VI and ARTICLE VII of this Agreement (other than those that, by their nature, are to be satisfied at the Closing, but subject to the satisfaction of those conditions at Closing, or the waiver of those conditions at Closing by the Party in whose favor any such condition runs). With respect to each Aircraft other than the Tranche 1 Aircraft, Purchaser and Seller shall mutually agree on the scheduled Closing Date therefor, provided that such scheduled Closing Date shall not be fewer than [***] following the date that the Aircraft [***] is at the Delivery Location and available for Physical Inspection but without limiting any of Purchaser’s rights or remedies under ARTICLE IV as to such Aircraft.

(b)The Closing with respect to each Aircraft shall, subject to the terms and conditions of this Agreement including ARTICLE VI and ARTICLE VII hereof, occur on the applicable Closing Date for such Aircraft. All actions that will be taken and all documents that will be executed and delivered by the Parties at each Closing will be deemed to have been taken and executed simultaneously, and no action will be deemed taken nor any document executed and delivered until all such actions have been taken, and all such documents have been executed and delivered.

Section 5.4. Final Closing Date. The Parties shall use commercially reasonable efforts to cause the Closing of each Aircraft to occur on or prior to [***] or such other date as may be mutually agreed in writing by the Parties (the “Final Closing Date”). If the Closing in respect of any Aircraft has not occurred prior to the Final Closing Date, then Purchaser shall have the right (except in any circumstance with respect to which Seller is entitled to terminate this Agreement under Section 12.2 due to a default by Purchaser that has not been cured in accordance therewith), exercisable by written notice to Seller, to terminate its obligations in the Definitive Documentation with respect to such Aircraft upon which Section 3.2 shall apply.

Section 5.5. Exclusivity. Each Mesa Party shall not, and shall cause its subsidiaries and affiliates not to, (a) solicit, encourage, or initiate the submission of proposals or offers from, (b) furnish or provide any confidential or non-public information to, (c) participate in discussions or negotiations with, or (d) enter into any agreement, arrangement, or understanding with, any person (other than Purchaser and its affiliates and representatives), in each case of the foregoing clauses (a) through (d) concerning the sale, transfer or disposition of any Aircraft, or any portion thereof, or any rights relating thereto [***] Immediately upon the execution and delivery of this Agreement, each Mesa Party shall, and shall cause its subsidiaries and affiliates to, (x) cease and terminate any and all existing discussions and/or negotiations with any person (other than Purchaser and its affiliates and representatives) regarding or relating in any way to any sale, transfer or disposition of the Aircraft or any rights relating [***] and (y) close access to any and all data rooms (virtual or otherwise) to any such persons.
