          WHEREAS, US Airways, the Pass Through Trustee, another other pass through trustee and certain
other persons concurrently herewith are entering into the Note Purchase Agreement, dated as of the

of the date hereof between the Depositary and the Escrow
Agent relating to the Pass Through Trust (as amended, modified, supplemented or replaced from
time to time in accordance with the terms thereof, the “Deposit Agreement”, which shall
also be deemed to refer to any Replacement Deposit Agreement (as defined in the Note Purchase
Agreement) to which the Escrow Agent becomes a party pursuant to Section 1.02(a) hereof from and

          NOW, THEREFORE, in consideration of the obligations contained herein, and for other good and
valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties
hereto hereby agree as follows:

          SECTION 1. Escrow Agent.

          Section 1.01. Appointment of Escrow Agent. Each of the Underwriters, for and on behalf of
each of the Investors, hereby irrevocably appoints, authorizes and directs the Escrow Agent to act
as escrow agent and fiduciary hereunder and under the Deposit Agreement for such specific purposes
and with such powers as are specifically delegated to the Escrow Agent by the terms of this
Agreement, together with such other powers as are reasonably incidental thereto. Any and all money
received and held by the Escrow Agent under this Agreement or the Deposit Agreement shall be held
in escrow by the Escrow Agent in accordance with the terms of this Agreement. This Agreement is
irrevocable and the Investors’ and the Pass Through Trustee’s rights with respect to any monies
received and held in escrow by the Escrow Agent under this Agreement or the Deposit Agreement shall
only be as provided under the terms and conditions of this Agreement and the Deposit Agreement.
The Escrow Agent (which term as used in this sentence shall include reference to its affiliates and
its own and its affiliates’ officers, directors, employees and agents): (a) shall have no duties or
responsibilities except those expressly set forth in this Agreement; (b) shall not be responsible
to the Pass Through Trustee or the Investors for any recitals, statements, representations or
warranties of any person other than itself contained in this Agreement or the Deposit Agreement or
for the failure by the Pass Through Trustee, the Investors or any other person or entity (other
than the Escrow Agent) to perform any of its obligations hereunder (whether or not the Escrow Agent
shall have any knowledge thereof); and (c) shall not be responsible for any action taken or omitted
to be taken by it hereunder or provided for herein or in connection herewith, except for its own
willful misconduct or gross negligence (or simple negligence in connection with the handling of
funds).

          Section 1.02. Instruction; Etc. The Underwriters, for and on behalf of each of the
Investors, hereby irrevocably instruct the Escrow Agent, and the Escrow Agent agrees:

          (a) to enter into the Deposit Agreement, and, if requested by the Company pursuant to
Section 4(a)(vi) of the Note Purchase Agreement, to enter into a Replacement Deposit
Agreement with the Replacement Depositary specified by the Company;

          (b) to appoint the Paying Agent as provided in this Agreement;

          (c) upon receipt at any time and from time to time prior to the Termination Date (as
defined below) of a certificate substantially in the form of Exhibit B hereto (a
“Withdrawal Certificate”) executed by the Pass Through Trustee, together with an
attached Notice of Purchase Withdrawal in substantially the form of Exhibit A to the Deposit
Agreement duly completed by the Pass Through Trustee (the “Applicable Notice of Purchase
Withdrawal” and the withdrawal to which it relates, a “Purchase Withdrawal”),
immediately to execute the Applicable Notice of Purchase Withdrawal as Escrow Agent and
transmit it to the Depositary by facsimile transmission in accordance with the Deposit
Agreement; provided that, upon the request of the Pass Through Trustee after such
transmission, the Escrow Agent shall cancel such Applicable Notice of Purchase Withdrawal;

          (d) upon receipt of a Withdrawal Certificate executed by the Pass Through Trustee,
together with an attached Notice of Replacement Withdrawal in substantially the form of
Exhibit C to the Deposit Agreement duly completed by the Pass Through Trustee, to:

          (X) give such Notice of Replacement Withdrawal to the Depositary requesting a
withdrawal, on the date specified in such notice, which shall not be less than five
Business Days after such notice is given (the “Replacement Withdrawal
Date”), of all Deposits then held by the Depositary together with all accrued
and unpaid interest on such Deposits to but excluding the Replacement Withdrawal
Date; and

          (Y) direct the Depositary to transfer such Deposits and accrued interest on
behalf of the Escrow Agent to the Replacement Depositary in accordance with the
Replacement Deposit Agreement; and

          (e) if there are any undrawn Deposits (as defined in the Deposit Agreement) on the
“Termination Date”, which shall mean the earlier of (i) January 21, 2011, and (ii)
the day on which the Escrow Agent receives notice from the Pass Through Trustee that the
Pass Through Trustee’s obligation to purchase Equipment Notes under the Note Purchase
Agreement has terminated, to immediately give notice to the Depositary (with a copy to the
Paying Agent) substantially in the form of Exhibit B to the Deposit Agreement requesting a
withdrawal of all of the remaining Deposits, together with accrued and unpaid interest on
such Deposits to the date of withdrawal, on the 25th day after the date that such
notice of withdrawal is given to the Depositary (or, if not a Business Day, on the next
succeeding Business Day) (a “Final Withdrawal”), provided that if the day
scheduled for the Final Withdrawal in accordance with the foregoing is

3

 

within 10 days before
or after a Regular Distribution Date, then the Escrow Agent shall request that such
requested Final Withdrawal be made on such Regular Distribution Date (the date of such
requested withdrawal, the “Final Withdrawal Date”).

If for any reason the Escrow Agent shall have failed to give the Final Withdrawal Notice to the
Depositary on or before January 31, 2011, and there are unwithdrawn Deposits on such date, the
Final Withdrawal Date shall be deemed to be February 21, 2011.

          Section 1.03. Initial Escrow Amount; Issuance of Escrow Receipts. The Escrow Agent hereby
directs the Underwriters to, and the Underwriters hereby acknowledge that on the date hereof they
shall, irrevocably deliver to the Depositary on behalf of the Escrow Agent, an amount in U.S.
dollars (“Dollars”) and immediately available funds equal to $77,398,000 for deposit on
behalf of the Escrow Agent with the Depositary in accordance with Section 2.1 of the Deposit
Agreement. The Underwriters hereby instruct the Escrow Agent, upon receipt of such sum from the
Underwriters, to confirm such receipt by executing and delivering to the Pass Through Trustee an
Escrow Receipt in the form of Exhibit A hereto (an “Escrow Receipt”), (a) to be affixed by
the Pass Through Trustee to each Certificate and (b) to evidence the same percentage interest (the
“Escrow Interest”) in the Account Amounts (as defined below) as the Fractional Undivided
Interest in the Pass Through Trust evidenced by the Certificate to which it is to be affixed. The
Escrow Agent shall provide to the Pass Through Trustee for attachment to each Certificate newly
issued under and in accordance with the Pass Through Trust Agreement an executed Escrow Receipt as
the Pass Through Trustee may from time to time request of the Escrow Agent. Each Escrow Receipt
shall be registered by the Escrow Agent in a register (the “Register”) maintained by the
Escrow Agent in the name of the same holder that is the holder of the Certificate to which it is
attached and may not thereafter be detached from such Certificate to which it is to be affixed
prior to the distribution of the Final Withdrawal (the “Final Distribution”). After the
Final Distribution, no additional Escrow Receipts shall be issued and the Pass Through Trustee
shall request the return to the Escrow Agent for cancellation of all outstanding Escrow Receipts.

          Section 1.04. Payments to Receiptholders. All payments and distributions made to holders
of an Escrow Receipt (collectively “Receiptholders”) in respect of the Escrow Receipt shall
be made only from amounts deposited in the Paying Agent Account (as defined below) (“Account
Amounts”). Each Receiptholder, by its acceptance of an Escrow Receipt, agrees that (a) it will
look solely to the Account Amounts for any payment or distribution due to such Receiptholder
pursuant to the terms of the Escrow Receipt and this Agreement (subject to Section 15 hereof) and
(b) it will have no recourse to US Airways, the Pass Through Trustee, the Paying Agent or the
Escrow Agent, except as expressly provided herein or in the Pass Through Trust Agreement. No
Receiptholder shall have any right to vote or in any manner otherwise control the operation and
management of the Paying Agent Account or the obligations of the parties hereto, nor shall anything
set forth herein, or contained in the terms of the Escrow Receipt, be construed so as to constitute
the Receiptholders from time to time as partners or members of an association.

          Section 1.05. Mutilated, Destroyed, Lost or Stolen Escrow Receipt. If (a) any
mutilated Escrow Receipt is surrendered to the Escrow Agent or the Escrow Agent receives evidence
to its satisfaction of the destruction, loss or theft of any Escrow Receipt and (b) there is
delivered to the Escrow Agent and the Pass Through Trustee such security, indemnity or bond,

4

 

as may
be required by them to hold each of them harmless, then, absent notice to the Escrow Agent or the
Pass Through Trustee that such destroyed, lost or stolen Escrow Receipt has been acquired by a bona
fide purchaser, and provided that the requirements of Section 8-405 of the Uniform Commercial Code
in effect in any applicable jurisdiction are met, the Escrow Agent shall execute, authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Escrow
Receipt, a new Escrow Receipt or Escrow Receipts and of like Escrow Interest in the Account Amounts
and bearing a number not contemporaneously outstanding.

          In connection with the issuance of any new Escrow Receipt under this Section 1.05, the Escrow
Agent may require the payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto and any other expenses (including the fees and expenses of
the Pass Through Trustee and the Escrow Agent) connected therewith.

          Any duplicate Escrow Receipt issued pursuant to this Section 1.05 shall constitute conclusive
evidence of the appropriate Escrow Interest in the Account Amounts, as if originally issued,
whether or not the lost, stolen or destroyed Escrow Receipt shall be found at any time.

          The provisions of this Section are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost
or stolen Escrow Receipts.

5

 

          Section 1.06. Additional Escrow Amounts. On the date of any Purchase Withdrawal, the Pass
Through Trustee may re-deposit with the Depositary some or all of the amounts so withdrawn in
accordance with Section 2.4 of the Deposit Agreement.

          Section 1.07. Resignation or Removal of Escrow Agent. Subject to the appointment and
acceptance of a successor Escrow Agent as provided below, the Escrow Agent may resign at any time
by giving 30 days’ prior written notice thereof to the Investors, but may not otherwise be removed
except for cause by the written consent of the Investors with respect to Investors representing
Escrow Interests aggregating not less than a majority in interest in the Account Amounts (an
“Action of Investors”). Upon any such resignation or removal, the Investors, by an Action
of Investors, shall have the right to appoint a successor Escrow Agent. If no successor Escrow
Agent shall have been so appointed and shall have accepted such appointment within 30 days after
the retiring Escrow Agent’s giving of notice of resignation or the removal of the retiring Escrow
Agent, then the retiring Escrow Agent may appoint a successor Escrow Agent. Any successor Escrow
Agent shall be a bank which has an office in the United States with a combined capital and surplus
of at least $100,000,000. Upon the acceptance of any appointment as Escrow Agent hereunder by a
successor Escrow Agent, such successor Escrow Agent shall enter into such documents as the Pass
Through Trustee shall require and shall thereupon succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Escrow Agent, and the retiring Escrow Agent shall be
discharged from its duties and obligations hereunder. No resignation or removal of the Escrow
Agent shall be effective unless a written confirmation shall have been obtained from each of
Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services, a Standard & Poor’s
Financial Services LLC business, that the replacement of the Escrow Agent with the successor Escrow
Agent will not result in (a) a reduction of the rating for the Certificates below the then current
rating for the Certificates or (b) a withdrawal or suspension of the rating of the Certificates.

          Section 1.08. Persons Deemed Owners. Prior to due presentment of a Certificate for
registration of transfer, the Escrow Agent and the Paying Agent may treat the Person in whose name
any Escrow Receipt is registered (as of the day of determination) as the owner of such Escrow
Receipt for the purpose of receiving distributions pursuant to this Agreement and for all other
purposes whatsoever, and neither the Escrow Agent nor the Paying Agent shall be affected by any
notice to the contrary.

          Section 1.09. Further Assurances. The Escrow Agent agrees to take such actions, and
execute such other documents, as may be reasonably requested by the Pass Through
Trustee in order to effectuate the purposes of this Agreement and the performance by the Escrow
Agent of its obligations hereunder.

          SECTION 2. Paying Agent.

          Section 2.01. Appointment of Paying Agent. The Escrow Agent hereby irrevocably
appoints and authorizes the Paying Agent to act as its paying agent hereunder, for the benefit of
the Investors, for such specific purposes and with such powers as are specifically delegated to the
Paying Agent by the terms of this Agreement, together with such other powers as are reasonably
incidental thereto. Any and all money received and held by the Paying Agent under this Agreement
or the Deposit Agreement shall be held in the Paying Agent Account for the benefit of the
Investors. The Paying Agent (which term as used in this sentence shall

6

 

include reference to its
affiliates and its own and its affiliates’ officers, directors, employees and agents): (a) shall
have no duties or responsibilities except those expressly set forth in this Agreement, and shall
not by reason of this Agreement be a trustee for the Escrow Agent; (b) shall not be responsible to
the Escrow Agent for any recitals, statements, representations or warranties of any person other
than itself contained in this Agreement or for the failure by the Escrow Agent or any other person
or entity (other than the Paying Agent) to perform any of its obligations hereunder (whether or not
the Paying Agent shall have any knowledge thereof); and (c) shall not be responsible for any action
taken or omitted to be taken by it hereunder or provided for herein or in connection herewith,
except for its own willful misconduct or gross negligence (or simple negligence in connection with
the handling of funds).

          Section 2.02. Establishment of Paying Agent Account. The Paying Agent shall establish a
deposit account (the “Paying Agent Account”) at Wilmington Trust Company in the name of the
Escrow Agent. It is expressly understood by the parties hereto that the Paying Agent is acting as
the paying agent of the Escrow Agent hereunder and that no amounts on deposit in the Paying Agent
Account constitute part of the Trust Property.

          Section 2.03. Payments from Paying Agent Account. The Escrow Agent hereby irrevocably
instructs the Paying Agent, and the Paying Agent agrees to act, as follows:

          (a) On each Interest Payment Date (as defined in the Deposit Agreement) or as soon
thereafter as the Paying Agent has confirmed receipt in the Paying Agent Account from the
Depositary of any amount in respect of accrued interest on the Deposits, the Paying Agent
shall distribute out of the Paying Agent Account the entire amount deposited therein by the
Depositary. There shall be so distributed to each Receiptholder of record on the 15th day
(whether or not a Business Day) preceding such Interest Payment Date by check mailed to such
Receiptholder, at the address appearing in the Register, such Receiptholder’s pro rata share
(based on the Escrow Interest in the Account Amounts held by such Receiptholder) of the
total amount of interest deposited by the Depositary in the Paying Agent Account on such
date, except that, with respect to Escrow Receipts registered on the Record Date in the name
of The Depository Trust Company (“DTC”), such distribution shall be made by wire
transfer in immediately available funds to the account designated by DTC.

          (b) Upon the confirmation by the Paying Agent of receipt in the Paying Agent Account
from the Depositary of any amount in respect of the Final Withdrawal, the Paying Agent shall
forthwith distribute the entire amount of the Final
Withdrawal deposited therein by the Depositary. There shall be so distributed to each
Receiptholder of record on the 15th day (whether or not a Business Day) preceding the Final
Withdrawal Date by check mailed to such Receiptholder, at the address appearing in the
Register, such Receiptholder’s pro rata share (based on the Escrow Interest in the Account
Amounts held by such Receiptholder) of the total amount in the Paying Agent Account on
account of such Final Withdrawal, except that, with respect to Escrow Receipts registered on
the Record Date in the name of DTC, such distribution shall be made by wire transfer in
immediately available funds to the account designated by DTC.

          (c) If any payment of interest or principal in respect of the Final Withdrawal is not
received by the Paying Agent within five days of the applicable date

7

 

when due, then it shall
be distributed to Receiptholders after actual receipt by the Paying Agent on the same basis
as a Special Payment is distributed under the Pass Through Trust Agreement.

          (d) The Paying Agent shall include with any check mailed pursuant to this Section any
notice required to be distributed under the Pass Through Trust Agreement that is furnished
to the Paying Agent by the Pass Through Trustee.

          Section 2.04. Withholding Taxes. The Paying Agent shall exclude and withhold from each
distribution of accrued interest on the Deposits (as defined in the Deposit Agreement) and any
amount in respect of the Final Withdrawal any and all withholding taxes applicable thereto as
required by law. The Paying Agent agrees to act as such withholding agent and, in connection
therewith, whenever any present or future taxes or similar charges are required to be withheld with
respect to any amounts payable in respect of the Deposits (as defined in the Deposit Agreement) or
the escrow amounts, to withhold such amounts and timely pay the same to the appropriate authority
in the name of and on behalf of the Receiptholders, that it will file any necessary withholding tax
returns or statements when due, and that, as promptly as possible after the payment thereof, it
will deliver to each such Receiptholder appropriate documentation showing the payment thereof,
together with such additional documentary evidence as such Receiptholder may reasonably request
from time to time. The Paying Agent agrees to file any other information reports as it may be
required to file under United States law.

          Section 2.05. Resignation or Removal of Paying Agent. Subject to the appointment and
acceptance of a successor Paying Agent as provided below, the Paying Agent may resign at any time
by giving 30 days’ prior written notice thereof to the Escrow Agent, but may not otherwise be
removed except for cause by the Escrow Agent. Upon any such resignation or removal, the Escrow
Agent shall have the right to appoint a successor Paying Agent. If no successor Paying Agent shall
have been so appointed and shall have accepted such appointment within 30 days after the retiring
Paying Agent’s giving of notice of resignation or the removal of the retiring Paying Agent, then
the retiring Paying Agent may appoint a successor Paying Agent. Any successor Paying Agent shall
be a bank which has an office in the United States with a combined capital and surplus of at least
$100,000,000. Upon the acceptance of any appointment as Paying Agent hereunder by a successor
Paying Agent, such successor Paying Agent shall enter into such documents as the Escrow Agent shall
require and shall thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Paying Agent, and the retiring Paying Agent shall be discharged from its
duties and obligations hereunder.

          Section 2.06. Notice of Final Withdrawal. Promptly after receipt by the Paying Agent
of notice that the Escrow Agent has requested a Final Withdrawal or that a Final Withdrawal will be
made, the Paying Agent shall cause notice of the distribution of the Final Withdrawal to be mailed
to each of the Receiptholders at its address as it appears in the Register. Such notice shall be
mailed not less than 15 days prior to the Final Withdrawal Date. Such notice shall set forth:

          (i) the Final Withdrawal Date and the date for determining Receiptholders of
record who shall be entitled to receive distributions in respect of the Final
Withdrawal,

8

 

          (ii) the amount of the payment in respect of the Final Withdrawal for each
$1,000 face amount Certificate (based on information provided by the Pass Through
Trustee) and the amount thereof constituting unused Deposits (as defined in the
Deposit Agreement) and interest thereon, and

          (iii) if the Final Withdrawal Date is the same date as a Regular Distribution
Date, the total amount to be received on such date for each $1,000 face amount
Certificate (based on information provided by the Pass Through Trustee).

          Such mailing may include any notice required to be given to Certificateholders in connection
with such distribution pursuant to the Pass Through Trust Agreement.

          SECTION 3. Payments. If, notwithstanding the instructions in Section 4 of the Deposit
Agreement that all amounts payable to the Escrow Agent under the Deposit Agreement be paid by the
Depositary directly to the Paying Agent, the Pass Through Trustee or a Replacement Depositary
(depending on the circumstances), the Escrow Agent receives any payment thereunder, then the Escrow
Agent shall forthwith pay such amount in Dollars and in immediately available funds by wire
transfer to (a) in the case of a payment of accrued interest on the Deposits (as defined in the
Deposit Agreement) or any Final Withdrawal, directly to the Paying Agent Account, (b) in the case
of any Purchase Withdrawal, directly to the Pass Through Trustee or its designee as specified and
in the manner provided in the Applicable Notice of Purchase Withdrawal and (c) in the case of any
Replacement Withdrawal, to the Replacement Depositary as provided in the Replacement Depositary
Agreement. The Escrow Agent hereby waives any and all rights of set-off, combination of accounts,
right of retention or similar right (whether arising under applicable law, contract or otherwise)
it may have against amounts payable to the Paying Agent howsoever arising.

          SECTION 4. Other Actions. The Escrow Agent shall take such other actions under or in
respect of the Deposit Agreement (including, without limitation, the enforcement of the obligations
of the Depositary thereunder) as the Investors, by an Action of Investors, may from time to time
request.

          SECTION 5. Representations and Warranties of the Escrow Agent. The Escrow Agent
represents and warrants to US Airways, the Investors, the Paying Agent and the Pass Through Trustee
as follows:

          (i) it is a national banking association duly organized and validly existing in
good standing under the laws of the United States of America;

          (ii) it has full power, authority and legal right to conduct its business and
operations as currently conducted and to enter into and perform its obligations
under this Agreement, the Deposit Agreement and any Replacement Deposit Agreement;

          (iii) the execution, delivery and performance of each of this Agreement, the
Deposit Agreement and any Replacement Deposit Agreement have been duly authorized by
all necessary corporate action on the part of it and

9

 

do not require any stockholder
approval, or approval or consent of any trustee or holder of any indebtedness or

          SECTION 7. Indemnification. Except for actions expressly required of the Escrow Agent or
the Paying Agent hereunder, each of the Escrow Agent and the Paying Agent shall in all cases be
fully justified in failing or refusing to act hereunder unless it shall have been indemnified by
the party requesting such action in a manner reasonably satisfactory to it against any and all
liability and expense which may be incurred by it by reason of taking or continuing to take any
such action. In the event US Airways requests any amendment to any Operative Agreement (as defined

expenses (including, without limitation, fees and disbursements of counsel) of the Escrow Agent and
the Paying Agent in connection therewith.

          SECTION 8. Amendment, Etc. Upon request of the Pass Through Trustee and approval by

and without any consent of the Investors, the Escrow Agent and Paying Agent shall enter into an
amendment to this Agreement for any of the following purposes:

          (1) to correct or supplement any provision in this Agreement which may be defective or

Agreement, provided that any such action shall not materially adversely affect the
interests of the Investors; or

          (2) to comply with any requirement of the SEC, applicable law, rules or regulations of
any exchange or quotation system on which the Certificates are listed or any regulatory
body; or

     The Escrow Agent shall notify the Receiptholders in the event of a default in the payment of
interest on the Deposits when due in accordance with the Deposit Agreement or a default in the
payment of any Final Withdrawal in accordance with the terms of the Deposit Agreement and this

case of the Escrow Agent and the Paying Agent) their respective permitted assigns. Upon the

Agreement (as defined below), the Pass Through Trustee shall (without further act) be deemed to

agreements, conditions and understandings among the Escrow Agent, the Paying Agent, the
Underwriters and the Pass Through Trustee with respect to the subject matter hereof, and supersedes
all prior and contemporaneous agreements and undertakings, inducements or conditions, express or
implied, oral or written.

          SECTION 12. Governing Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York.

          SECTION 13. Waiver of Jury Trial Right. EACH OF THE ESCROW AGENT, THE PAYING AGENT, THE

ACKNOWLEDGES AND ACCEPTS THAT IN ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT SUCH PARTY IRREVOCABLY WAIVES ITS RIGHT TO A TRIAL BY JURY.

13

 

          SECTION 14. Counterparts. This Agreement may be executed in one or more counterparts, all
of which taken together shall constitute one instrument.

          SECTION 15. Rights of Holders. Each Receiptholder shall have the right (individually and
without the need for any other action of any Person, including the Escrow Agent or any other
Receiptholder), upon any default in the payment of interest on the Deposits when due by the
Depositary in accordance with the Deposit Agreement, or upon any default in the payment of the
Final Withdrawal when due by the Depositary in accordance with the terms of the Deposit Agreement
and this Agreement, (i) to proceed directly against the Depositary by making a demand to the
Depositary for the portion of such payment that would have been distributed to such Receiptholder
pursuant to this Agreement or by bringing suit to enforce payment of such portion and (ii) to
enforce any other rights that the Escrow Agent may have in respect of amounts due from the
Depositary under the Deposit Agreement and this Agreement that would have been distributed to such
Receiptholder pursuant to this Agreement. Any recovery on such enforcement action shall belong
solely to the Receiptholder who brought such action, and not to the Escrow Agent or any other
Receiptholder individually or to Receiptholders as a group.

14

 

          IN WITNESS WHEREOF, the Escrow Agent, the Paying Agent, the Underwriters and the Pass Through

EXHIBIT A

US AIRWAYS 2010-1B ESCROW RECEIPT

No. __

          This Escrow Receipt evidences a fractional undivided interest in amounts (“Account
Amounts”) from time to time deposited on behalf of the holder hereof into a certain paying
agent account (the “Paying Agent Account”) described in the Escrow and Paying Agent
Agreement (Class B) dated as of December 21, 2010 (as amended, modified or supplemented from time
to time, the “Escrow and Paying Agent Agreement”) among Wells Fargo Bank Northwest,
National Association, as Escrow Agent (in such capacity, together with its successors in such
capacity, the “Escrow Agent”), Morgan Stanley & Co. Incorporated, Citigroup Global Markets
Inc. and Credit Suisse Securities (USA) LLC, as representatives of the several Underwriters,
Wilmington Trust Company, as Pass Through Trustee (in such capacity, together with its successors
in such capacity, the “Pass Through Trustee”) and Wilmington Trust Company, as paying agent
(in such capacity, together with its successors in such capacity, the “Paying Agent”).
Capitalized terms not defined herein shall have the meanings assigned to them in the Escrow and
Paying Agent Agreement.

          This Escrow Receipt is issued under and is subject to the terms, provisions and conditions of
the Escrow and Paying Agent Agreement. By virtue of its acceptance hereof the holder of this
Escrow Receipt assents and agrees to be bound by the provisions of the Escrow and Paying Agent
Agreement and this Escrow Receipt.

          This Escrow Receipt represents a fractional undivided interest in amounts deposited from time
to time in the Paying Agent Account, and grants or represents no rights, benefits or interests of
any kind in respect of any assets or property other than such amounts. This Escrow Receipt
evidences the same percentage interest in the Account Amounts as the Fractional Undivided Interest
in the Pass Through Trust evidenced by the Certificate to which this Escrow Receipt is affixed.

          All payments and distributions made to Receiptholders in respect of the Escrow Receipt shall
be made only from Account Amounts deposited in the Paying Agent Account. The holder of this Escrow
Receipt, by its acceptance of this Escrow Receipt, agrees that it will look solely to the Account
Amounts for any payment or distribution due to it pursuant to this Escrow Receipt (or, in case the
Depositary shall default in its obligation to make a payment under the Deposit Agreement that would
be an Account Amount, to the Depositary) and that it will not have any recourse to US Airways, the
Pass Through Trustee, the Paying Agent or the Escrow Agent, except as expressly provided herein or
in the Pass Through Trust Agreement. No Receiptholder of this Escrow Receipt shall have any right
to vote or in any manner otherwise control the operation and management of the Paying Agent
Account, nor shall anything set forth herein, or contained in the terms of this Escrow Receipt, be
construed so as to constitute the Receiptholders from time to time as partners or members of an
association.

          This Escrow Receipt may not be assigned or transferred except in connection with the
assignment or transfer of the Certificate to which this Escrow Receipt is affixed. After payment
to the holder hereof of its Escrow Interest in the Final Distribution, upon the request of

 

 

the Pass Through Trustee, the holder hereof will return this Escrow Receipt to the Pass
Through Trustee.

          The Paying Agent may treat the person in whose name the Certificate to which this Escrow
Receipt is attached as the owner hereof for all purposes, and the Paying Agent shall not be
affected by any notice to the contrary.

          THIS ESCROW RECEIPT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK.

          IN WITNESS WHEREOF, the Escrow Agent has caused this Escrow Receipt to be duly executed.

     SECTION 1. Financing of Aircraft. (a) The Company confirms that it currently owns
the Aircraft. The Company agrees to finance the Aircraft in the manner provided herein, all on and
subject to the terms and conditions hereof and of the relevant Financing Agreements.

     (b) In furtherance of the foregoing, the Company agrees to give the parties hereto, the
Depositary and each of the Rating Agencies not less than two Business Days’ prior notice
substantially in the form of Exhibit A hereto (a “Closing Notice”) of the scheduled closing
date (the “Scheduled Closing Date”) (or, in the case of a substitute Closing Notice
under Section

2

 

1(e) hereof, one Business Day’s prior notice) in respect of the financing of each
Aircraft under this Agreement, which notice shall:

     (i) specify the Scheduled Closing Date of such Aircraft (which shall be a Business Day before
the Cut-off Date and the date (the “Funding Date”) on which the financing therefor in the
manner provided herein shall be consummated);

     (ii) instruct each Pass Through Trustee being requested to purchase Equipment Notes pursuant
to such Closing Notice (the “Applicable Pass Through Trustees”)to enter into the
Participation Agreement included in the Financing Agreements with respect to such Aircraft in such
form and at such a time on or before the Funding Date specified in such Closing Notice and to
perform its obligations thereunder;

     (iii) instruct each of the Class A and Class B Pass Through Trustees to instruct the relevant
Escrow Agent to provide a Notice of Purchase Withdrawal to the Depositary with respect to the
Equipment Notes to be issued to such Pass Through Trustee in connection with the financing of such
Aircraft (except in the case of any such financing on the Issuance Date); and

     (iv) specify the aggregate principal amount of each series of Equipment Notes, if any, to be
issued, and purchased by the Applicable Pass Through Trustees, in connection with the financing of
such Aircraft scheduled on such Funding Date (which shall in all respects comply with the Required
Terms).

Notwithstanding the foregoing, in the case of any Aircraft to be financed hereunder on the Issuance
Date, the Closing Notice therefor may be delivered to the parties hereto on the Issuance Date.

     (c) Upon receipt of a Closing Notice, the Applicable Pass Through Trustees shall, and shall
cause the Subordination Agent to, enter into and perform their respective obligations under the
Participation Agreement specified in such Closing Notice, provided that such Participation
Agreement and the Trust Indenture to be entered into pursuant to such Participation Agreement shall
be in the forms thereof annexed hereto in all material respects and, if modified in any material
respect, as to which Rating Agency Confirmation shall have been obtained from each Rating Agency by
the Company (to be delivered by the Company to the Applicable Pass Through Trustees on or before
the relevant Funding Date, it being understood that if Rating Agency Confirmation shall have been
received with respect to any Financing Agreements and such Financing Agreements are utilized for
subsequent Aircraft without material modifications, no additional Rating Agency Confirmation shall
be required); provided, however, that the relevant Financing Agreements as executed
and delivered shall not vary the Required Terms. Notwithstanding the foregoing, a Trust Indenture
may be modified to the extent required for the issuance of Equipment Notes pursuant to Section
4(a)(v) of this Agreement, subject to the terms of such Section and Section 9.1(c) or 9.1(d) of the
Intercreditor Agreement, whichever may be applicable. The Company shall pay the reasonable costs
and expenses of the Rating Agencies in connection with obtaining any such Rating Agency
Confirmation. With respect to each Aircraft, the Company shall cause WTC (or such other person
that meets the eligibility requirements to act as indenture trustee under the Trust
Indenture) to execute as Indenture Trustee the Financing Agreements relating to such Aircraft
to

3

 

which such Indenture Trustee is intended to be a party, and shall concurrently therewith execute
such Financing Agreements to which the Company is intended to be a party and perform its respective
obligations thereunder. Upon the request of either Rating Agency, the Company shall deliver or
cause to be delivered to such Rating Agency a true and complete copy of each Financing Agreement
relating to the financing of each Aircraft together with a true and complete set of the closing
documentation (including legal opinions) delivered to the related Indenture Trustee, Subordination
Agent and Pass Through Trustee under the related Participation Agreement.

     (d) The Company agrees that all Equipment Notes issued pursuant to any Trust Indenture shall
initially be registered in the name of the Subordination Agent on behalf of the Applicable Pass
Through Trustee (or, in the case of any Additional Series Equipment Notes, on behalf of the
Additional Pass Through Trustee with respect to the corresponding Additional Certificates).

     (e) If on the Scheduled Closing Date of the Aircraft referred to therein the financing thereof
in the manner contemplated hereby shall not be consummated for whatever reason, the Company shall
give the parties hereto and the Depositary prompt notice thereof. Concurrently with the giving of
such notice of postponement or subsequently, the Company shall give the parties hereto and the
Depositary a substitute Closing Notice specifying the date to which the financing of such Aircraft
shall have been re-scheduled (which shall be a Business Day before the Cut-off Date on which the
Escrow Agents shall be entitled to withdraw one or more Deposits under each of the applicable
Deposit Agreements to enable each of the Class A and Class B Pass Through Trustees to fund its
purchase of the related Equipment Notes). Upon receipt of any such notice of postponement, each
Applicable Pass Through Trustee shall comply with its obligations under Section 5.01 of each of the
Trust Supplements and thereafter the financing of such Aircraft, as specified in such substitute
Closing Notice, shall take place on the re-scheduled Closing Date therefor (all on and subject to
the terms and conditions of the relevant Financing Agreements) unless further postponed as provided
herein.

     (f) The Company shall have no liability for the failure of the Pass Through Trustees to
purchase Equipment Notes with respect to any Aircraft.

     (g) Anything herein to the contrary notwithstanding, the Company shall not have the right, and
shall not be entitled, at any time to request the issuance of Equipment Notes of any series to the
Class A or Class B Pass Through Trustee in an aggregate principal amount in excess of the amount of
the Deposits then available for withdrawal by the Escrow Agent under and in accordance with the
provisions of the related Deposit Agreement.

     SECTION 2. Conditions Precedent. The obligation of the Applicable Pass Through
Trustees to enter into, and to cause the Subordination Agent to enter into, any Participation
Agreement as directed pursuant to a Closing Notice and to perform its obligations thereunder is
subject to satisfaction of the following conditions:

     (a) no Triggering Event shall have occurred; and

4

 

     (b) the Company shall have delivered a certificate to each such Pass Through Trustee and the
Liquidity Provider stating (i) that such Participation Agreement and the other Financing Agreements
to be entered into pursuant to such Participation Agreement do not vary the Required Terms and (ii)
that any substantive modification of such Financing Agreements from the forms of Financing
Agreements attached to this Agreement do not materially and adversely affect the Certificateholders
or the Liquidity Provider, and such certification shall be true and correct.

     Anything herein to the contrary notwithstanding, the obligation of each Pass Through Trustee
to purchase Equipment Notes shall terminate on the Cut-off Date.

     SECTION 4. Covenants. (a) The Company covenants with each of the other parties
hereto that:

     (i) subject to Section 4(a)(iii) of this Agreement, the Company shall at all times maintain
its corporate existence and shall not wind up, liquidate or dissolve or take any action, or fail to
take any action, that would have the effect of any of the foregoing;

     (ii) the Company shall at all times remain a U.S. Air Carrier (as defined in the Financing
Agreements) and shall at all times be otherwise certificated and registered to the extent necessary
to entitle the Indenture Trustee to the rights afforded to secured parties of aircraft equipment
under Section 1110;

     (iii) Section 4.07 of each Trust Indenture is hereby incorporated by reference herein;

8

 

     (iv) the Company agrees to provide written notice to each of the parties hereto of the
occurrence of the Cut-off Date no later than one Business Day after the date thereof, such notice
to refer specifically to the Pass Through Trustee’s obligation to assign, transfer and deliver all
of its right, title and interest to the Trust Property (as defined in each Pass Through Trust
Agreement) to the trustee of the Related Trust (as defined in each Pass Through Trust Agreement) in
accordance with Section 7.01 of each of the Trust Supplements;

     (v) the Company shall not redeem and re-issue any Series B Equipment Notes or issue any
Additional Series Equipment Notes pursuant to any Trust Indenture, unless it shall have obtained
written confirmation from each Rating Agency that the reissuance or issuance of such Equipment
Notes, as the case may be, will not result in (1) a reduction of the rating for any Class of
Certificates then rated by any Rating Agency that will remain outstanding below the then current
rating for such Class of Certificates or (2) a withdrawal or suspension of the rating of any Class
of Certificates then rated by any Rating Agency that will remain outstanding. Any reissuance of
the Series B Equipment Notes and issuance of Additional Series Equipment Notes shall be subject to
the terms of Section 9.1(c) and 9.1(d), respectively, of the Intercreditor Agreement; and

     (vi) If (x) the Depositary’s short-term unsecured debt rating or short-term issuer credit
rating, as the case may be, shall at any time fall below A-1+ from Standard & Poor’s Ratings
Services or P-1 from Moody’s Investors Service, Inc. (such minimum ratings, the “Depositary
Threshold Ratings”) or (y) the Company or the Depositary, in its sole discretion, gives written
notice to the other of its election that the Depositary be replaced, the Company shall, within 30
days after such event occurring, cause the Depositary to be replaced with a depositary bank (a
“Replacement Depositary”) on the following terms and preconditions:

     (A) the Replacement Depositary must meet the Depositary Threshold Ratings and the Company
shall have obtained written confirmation from each Rating Agency that such replacement will not
cause a reduction of any rating then in effect for any Class of Certificates by such Rating Agency
(without regard to any downgrading of any rating of the Depositary being replaced);

     (B) the Company shall pay all fees, expenses and other amounts then owing to the replaced
Depositary and, except as expressly provided in clause (C) below, the Company shall pay any
up-front fee of the Replacement Depositary and (without limitation of the foregoing) all
out-of-pocket expenses (including reasonable fees and expenses of legal counsel) of the parties
hereto (including without limitation all amounts payable to the Rating Agencies) incurred in
connection with such replacement;

     (C) solely in the case of the Depositary making an election in its discretion that it be
replaced (and without limitation of clause (A) above), (x) the notice given by the Depositary to
the Company shall nominate a Replacement Depositary, which shall satisfy all of terms and
preconditions of this Section 4(a)(vi) (and the Company shall have the right to utilize such
nominee as the Replacement Depositary or to select another Replacement Depositary), (y) the fees,
expenses, indemnities and other amounts payable to the Replacement Depositary upon its execution of
the Replacement Deposit Agreement or thereafter shall not to any extent exceed those which would
have been payable to the Depositary had such replacement not

9

 

occurred (it being specifically understood and agreed that any up-front fee of the Replacement Depositary
shall be paid by the replaced Depositary, provided that, if the Company selects a Replacement
Depositary other than the nominee of the replaced Depositary and the upfront fee of such selection
exceeds that of such nominee, the Company shall pay such excess), and (without limitation of the
foregoing) the Depositary shall pay all out-of-pocket expenses (including reasonable fees and
expenses of legal counsel) of the parties hereto (including without limitation all amounts payable
to the Rating Agencies) incurred in connection with such replacement, and (z) the Replacement
Depositary shall be willing to enter into a Replacement Deposit Agreement for each of the Class A
and Class B Certificates with the Escrow Agent having the same terms and conditions (including
without limitation as to the interest to be paid on the Deposits) as the Deposit Agreements to
which the Depositary is a party; and

     (D) the Company or, in the case of the Depositary making an election that it be replaced
(unless the Company shall have selected such Replacement Depositary), the Depositary, shall cause
the Replacement Depositary to enter into a Replacement Deposit Agreement for each of the Class A
and Class B Certificates with the Escrow Agent (and, upon request of the Company the Escrow Agent
agrees to enter into any such Replacement Deposit Agreement) and shall cause the Replacement
Depositary to deliver to the Company and each Rating Agency legal opinions and other closing
documentation substantially similar in scope and substance as those that were delivered by the
Depositary being replaced in connection with the execution and delivery of the Deposit Agreement
being replaced.

     Upon satisfaction of the foregoing conditions, the Company shall instruct the Class A Pass
Through Trustee and the Class B Pass Through Trustee, and each such Pass Through Trustee agrees, to
execute and deliver to the Escrow Agent a duly completed Withdrawal Certificate (as defined in the
Escrow and Paying Agent Agreements) together with a Notice of Replacement Withdrawal (as defined in
the Escrow and Paying Agent Agreements).

     Each of the parties hereto agrees, at the Company’s request, to enter into any amendments to
this Agreement, the Escrow and Paying Agent Agreements and any other Operative Agreements as may be
necessary or desirable to give effect to the replacement of the Depositary with the Replacement
Depositary and the replacement of the Deposit Agreements with the Replacement Deposit Agreements.

     Upon the execution and delivery of the Replacement Deposit Agreements, the Replacement
Depositary shall be deemed to be the Depositary with all of the rights and obligations of the
Depositary hereunder and under the other Operative Agreements and the Replacement Deposit
Agreements shall be deemed to be the Deposit Agreements hereunder and under the other Operative
Agreements, except that the obligations of the replaced Depositary under its Deposit Agreements
resulting from the delivery of any Withdrawal Notice delivered thereunder shall remain in full
force and effect notwithstanding the execution and delivery of the Replacement Deposit Agreements.

     (vii) Promptly after the occurrence of a Triggering Event or an Indenture Default resulting
from the failure of the Company to make payments on any Equipment Note and on every Regular
Distribution Date while the Triggering Event or such Indenture Default shall be continuing, the
Company will, at the Subordination Agent’s request from time to time but in any

10

 

event no more frequently than once every three months, provide to the Subordination Agent a
statement setting forth the following information with respect to each Aircraft then subject to the
lien of a Trust Indenture: (A) whether the Aircraft are currently in service or parked in storage,
(B) the maintenance status of the Aircraft and (C) the location of the Engines (as defined in the
respective Trust Indentures to which such Aircraft are subject). As used in this sentence, the
terms “Triggering Event”, “Indenture Default”, “Regular Distribution Date” shall have the
respective meanings set forth in the Intercreditor Agreement as originally executed.

     (b) WTC, in its individual capacity, covenants with each of the other parties to this
Agreement that it will, immediately upon obtaining knowledge of any facts that would cast doubt
upon its continuing status as a “citizen of the United States” as defined in Section 40102(a)(15)
of the Act and promptly upon public disclosure of negotiations in respect of any transaction which
would or might adversely affect such status, notify in writing all parties hereto of all relevant
matters in connection therewith. Upon WTC giving any such notice, WTC shall, subject to Section
9.01 of any Trust Indenture then entered into, resign as Indenture Trustee in respect of such Trust
Indenture.

     SECTION 5. Notices. Unless otherwise specifically provided herein, all notices
required or permitted by the terms of this Agreement shall be in English and in writing, and any
such notice shall become effective upon being delivered personally or, if promptly confirmed by
mail, when dispatched by facsimile or other written telecommunication, addressed to such party
hereto at its address or facsimile number set forth below the signature of such party at the foot
of this Agreement or to such other address or facsimile number as such party may hereafter specify
by notice to the other parties.

     SECTION 6. Expenses. (a) The Company agrees to pay to the Subordination Agent when
due an amount or amounts equal to the fees payable to the Liquidity Provider under Section 2.03 of
each Liquidity Facility and the related Fee Letter (as defined in the Intercreditor Agreement)
multiplied by a fraction the numerator of which shall be the then outstanding aggregate amount of
the Deposits under the Deposit Agreements pertaining to the Class A and Class B Pass Through Trusts
and the denominator of which shall be the sum of (x) the then outstanding aggregate principal
amount of the Series A Equipment Notes and Series B Equipment Notes issued under all of the Trust
Indentures and (y) the then outstanding aggregate amount of the Deposits under the Deposit
Agreements pertaining to the Class A and Class B Pass Through Trusts.

     (b) So long as no Equipment Notes have been issued in respect of any Aircraft, the Company
agrees to pay (i) to the Subordination Agent when due (A) the amount equal to interest on any
Downgrade Advance (other than any Applied Downgrade Advance) payable under Section 3.07 of each
Liquidity Facility minus Investment Earnings while such Downgrade Advance shall be outstanding, (B)
the amount equal to interest on any Non-Extension Advance (other than any Applied Non-Extension
Advance) payable under Section 3.07 of each Liquidity Facility minus Investment Earnings while such
Non-Extension Advance shall be outstanding, (C) the amount equal to interest on any Special
Termination Advance (other than any Applied Special Termination Advance) payable under Section 3.07
of each Liquidity Facility minus Investment Earnings from such Special Termination Advance while
such Special Termination Advance shall be outstanding, and (D) any other amounts owed to the
Liquidity

11

 

Provider by the Subordination Agent as borrower under each Liquidity Facility (other than
amounts due as repayment of advances thereunder or as interest on such advances, except to the
extent payable pursuant to clause (A), (B) or (C)), (ii) all compensation and reimbursement of
expenses, disbursements and advances payable by the Company under the Pass Through Trust
Agreements, (iii) all compensation and reimbursement of expenses and disbursements payable to the
Subordination Agent under the Intercreditor Agreement except with respect to any income or
franchise taxes incurred by the Subordination Agent in connection with the transactions
contemplated by the Intercreditor Agreement and (iv) in the event the Company requests any
amendment to any Operative Agreement, all reasonable fees and expenses (including, without
limitation, fees and disbursements of counsel) of the Escrow Agent and/or the Paying Agent in
connection therewith. For purposes of this Section 6(b), the terms “Applied Downgrade Advance”,
“Applied Non-Extension Advance”, “Applied Special Termination Advance”, “Downgrade Advance”,
“Investment Earnings”, “Non-Extension Advance” and “Special Termination Advance” shall have the
meanings specified in each Liquidity Facility.

     SECTION 7. Further Assurances. Each party hereto shall duly execute, acknowledge and
deliver, or shall cause to be executed, acknowledged and delivered, all such further agreements,
instruments, certificates or documents, and shall do and cause to be done such further acts and
things, in any case, as any other party hereto shall reasonably request in connection with its
administration of, or to carry out more effectually the purposes of, or to better assure and
confirm unto it the rights and benefits to be provided under, this Agreement.

     SECTION 8. Miscellaneous. (a) Provided that the transactions contemplated hereby
have been consummated, in whole or in part, and except as otherwise provided for herein, the
representations, warranties and agreements herein of the Company, the Subordination Agent, the
Escrow Agent, the Paying Agent and the Pass Through Trustee, and the Company’s, the Subordination
Agent’s, the Escrow Agent’s, the Paying Agent’s and the Pass Through Trustee’s obligations under
any and all thereof, shall survive the expiration or other termination of this Agreement and the
other agreements referred to herein.

     (b) This Agreement may be executed in any number of counterparts (and each of the parties
hereto shall not be required to execute the same counterpart). Each counterpart of this Agreement,
including a signature page executed by each of the parties hereto, shall be an original counterpart
of this Agreement, but all of such counterparts together shall constitute one instrument. Neither
this Agreement nor any of the terms hereof may be terminated, amended, supplemented, waived or
modified orally, but only by an instrument in writing signed by the party against which the
enforcement of the termination, amendment, supplement, waiver or modification is sought. The index
preceding this Agreement and the headings of the various Sections of this Agreement are for
convenience of reference only and shall not modify, define, expand or limit any of the terms or
provisions hereof. The terms of this Agreement shall be binding upon, and shall inure to the
benefit of, the Company and its successors and permitted assigns, the Pass Through Trustee and its
successors as Pass Through Trustee (and any additional trustee appointed) under any of the Pass
Through Trust Agreements, the Escrow Agent and its successors as Escrow Agent under the Escrow and
Paying Agent Agreements, the Paying Agent and its successors as Paying Agent under the Escrow and
Paying Agent Agreement and the

(other than the Underwriters, each of the beneficiaries of Section 6 hereof and the Depositary as a
beneficiary of Section 4(a)(vi)) with any rights of any nature whatsoever against any of the
parties hereto, and no person not a party hereto (other than the Underwriters, each of the
beneficiaries of Section 6 hereof and the Depositary as a beneficiary of Section 4(a)(vi)) shall
have any right, power or privilege in respect of, or have any benefit or interest arising out of,

6 hereof (including, but not limited to rights, powers, privileges, benefits, interests, remedies
and claims under Section 6) or to the Depositary with respect to Section 4(a)(vi), each such party
is hereby recognized as a third party beneficiary hereunder and may enforce any such right, power,
