     Bankruptcy Code, "US Airways"), US Airways Group, Inc. (including, as the
     context may require, as reorganized pursuant to the Bankruptcy Code,
     "Group"), America West Holdings Corporation ("Holdings"), America West
     Airlines, Inc. ("AWA"), General Electric Capital Corporation, acting
     through its agent GE Commercial Aviation Services LLC ("GECC"; and together
     with GE Commercial Aviation Services LLC ("GECAS"), GE Engine Services,
     Inc. and GE Engine Services - Dallas, LP (collectively, "GE Engine
     Services"), and General Electric Company, GE Transportation Component
     ("GEAE") and their respective affiliates, the "GE Entities")/Amendment to
     Original MOU (as hereinafter defined)

Ladies and Gentlemen:
<PAGE>
This Merger MOU, when countersigned by the respective parties, shall set forth
our understanding with respect to the restructuring of certain of the
indebtedness and obligations of US Airways and Group to the GE Entities, and the
restructuring of certain of the indebtedness and obligations of Holdings and AWA
to the GE Entities, both in connection with that certain merger transaction
described in the Agreement and Plan of Merger filed on May 20, 2005 with the
Bankruptcy Court as defined below (the "Merger"), which understanding was
reached in separate negotiations with each of such respective parties in
connection with the related matters contained herein.

I.   Relationship to Original MOU

Reference is made to the Amended and Restated Master Memorandum of
Understanding, dated as of November 24, 2004 (as amended prior to the date
hereof, the "Original MOU"), among US Airways, Group and the GE Entities. Terms
used herein and in the Supplemental Merger Term Sheets (as defined below) and
not otherwise defined have the meanings given to them in the Original MOU.

The parties hereto agree that the Original MOU remains in effect and operative
in connection with the Merger and that this Merger MOU shall be interpreted as
being supplemental to the Original MOU, with the result that the Phase II
Transactions and the Exit Transactions as described in the Original MOU, as
supplemented hereby, shall continue to be implemented in the manner provided by
the Original MOU except as otherwise expressly provided to the contrary herein.
In accordance with the foregoing statement of intent concerning the
supplementary nature of this Merger MOU to the Original MOU, the parties hereto
agree that the Original MOU and this Merger MOU shall be interpreted to the
maximum extent possible in a manner that reconciles any inconsistencies between
them; provided, however, that, in the event of a direct irreconcilable conflict
between the Original MOU and this Merger MOU, the terms of this Merger MOU shall
control. In furtherance of the foregoing, the Global Events of Default stated in
the Original MOU are hereby deleted in their entirety and replaced with each of
the Merger Events of Default hereunder and, accordingly, each Merger Event of
Default hereunder shall constitute a Global Event of Default under the Original
MOU and in each document referencing the Original MOU.

II.  Supplemental Terms regarding the Original MOU to provide for Certain
     Additional Restructuring Transactions.

A.   US Airways and AWA Lease and Finance Arrangements

In conjunction with the bankruptcy proceedings of Group and certain of its
subsidiaries (including US Airways) under Chapter 11, Title 11 of the United
States Code (the "Chapter 11 Case") commenced on September 12, 2004 (the
"Petition Date") in the United States Bankruptcy Court for the Eastern District
of Virginia, Alexandria Division (the "Bankruptcy Court"), and in conjunction
with the Merger, US Airways and AWA wish to obtain and GECAS is willing to
provide (both during the Chapter 11 Case and upon the effective date of a plan
of reorganization ("Plan of Reorganization") confirmed

                                       2
<PAGE>
by the Bankruptcy Court (the "Emergence" and "Emergence Date", as the case may
be) that provides for the Merger and other transactions contemplated hereby in
accordance with this Merger MOU, and both prior to the closing of the Merger and
upon closing of the Merger as provided herein) the following transactions to
supplement the Phase II Transactions and Exit Transactions contemplated by the
Original MOU: (i) certain lease modifications to shorten the terms of various
leases with respect to certain GECC aircraft leased to US Airways, and with
respect to certain GE Entities' aircraft leased to AWA, and certain related
lease amendments, as described in Exhibit A; (ii) certain acknowledgments
regarding the existing bridge facility to US Airways from a GE Entity and
certain lease modifications related to the rent under various leases, as
described in Exhibit B; (iii) certain arrangements in respect of regional jet
leases and financings with US Airways, as described in Exhibit C; (iv) certain
modifications to the financing provided by GE Entities to AWA in respect of
Spare Parts, as described in Exhibit D; (v) certain amendments to the Phase II
Transactions between GECAS and US Airways, as described in Exhibit E; and (vi)
certain modifications with respect to certain of the contracts between US
Airways and GE Engine Services and GEAE, as described in Exhibit F.

B.   General Conditions

Each of the transactions and modifications described herein is to occur,
together with the Phase II Transactions and Exit Transactions described in the
Original MOU, as supplemented hereby, pursuant to the terms and conditions set
forth in the following applicable term sheets attached as Exhibits A through F
(each, a "Supplemental Merger Term Sheet" and, collectively, the "Supplemental
Merger Term Sheets"). Certain of the transactions and modifications described in
the Supplemental Merger Term Sheets are scheduled to take effect as described
therein prior to the Emergence Date and the closing of the Merger (the
"Pre-Merger Transactions"); and others are scheduled to take effect upon or
after the Emergence Date and the closing of the Merger as described in the
attached Supplemental Merger Term Sheets (the "Merger Transactions" and,
together with the Pre-Merger Transactions, the Phase II Transactions and the
Exit Transactions, the "Restructuring Transactions").

The parties further acknowledge and agree that (i) the Restructuring
Transactions contemplated in this Merger MOU and the Original MOU are comprised
of several separate interrelated transactions (each of which is individually
described in its respective Term Sheet), and (ii) each Pre-Merger Transaction,
Merger Transaction, Phase II Transaction and Exit Transaction is expressly
conditioned upon the consummation of every other Pre-Merger Transaction, Merger
Transaction, Phase II Transaction and Exit Transaction, as applicable. In no
event shall any Supplemental Merger Term Sheet be viewed as a stand-alone
transaction. Accordingly, each of the transactions and modifications
contemplated by the Supplemental Merger Term Sheets must be evidenced by
executed definitive agreements in order to effectuate the Restructuring
Transactions.

Each of the Pre-Merger Transactions, the Merger Transactions, the Phase II
Transactions and the Exit Transactions shall only take effect on the effective
dates and, in each case

                                       3
<PAGE>
subject to the satisfaction of applicable conditions, for such transactions
(whether such conditions are provided for in the schedules to this Merger MOU or
in the schedules to the Original MOU or in the applicable Supplemental Merger
Term Sheet or Term Sheet); provided, however, that to the extent an individual
transaction under any of the Supplemental Merger Term Sheets to this Merger MOU
or the Term Sheets to the Original MOU is consummated prior to the Merger and/or
the Emergence Date, and without waiving or otherwise affecting any of the other
terms and conditions of the Original MOU or the Term Sheets, this Merger MOU or
the Supplemental Merger Term Sheets, such transaction shall be effective
nevertheless and shall not be reversed or rescinded even if the Merger and/or
such emergence does not occur.

Each and every obligation of US Airways or Group to a GE Entity, or of Holdings
or AWA to a GE Entity, or to another party where nonperformance of such
obligation could impose an obligation on a GE Entity, which may be created under
this Merger MOU, the Original MOU and the Supplemental Merger Term Sheets
hereunder and the Term Sheets thereunder (such obligations, the "Restructuring
Obligations") will be, subject to the last sentence of this paragraph, (i)
cross-defaulted to each and every Restructuring Obligation unless such
cross-default has specifically been waived by the affected GE Entity or in this
Merger MOU or in the Original MOU or in the Supplemental Merger Term Sheets or
Term Sheets, as applicable, and (ii) cross-defaulted with the cash collateral
order in respect of the existing loan guaranteed by the Air Transportation
Stabilization Board (the "ATSB") in accordance with the Air Carrier Guarantee
Loan Program (the "ATSB Loan"). Upon Emergence, any agreement between US Airways
and/or Group and a GE Entity, or Holdings and/or AWA and a GE Entity, which
contains a cross-default to other obligations owing a GE Entity shall be amended
to include any obligations of US Airways or AWA, and their affiliates, to a GE
Entity, subject to any qualifications and conditions in such cross-default
provision. After the Emergence Date and consummation of the Merger, (x) US
Airways and Group shall guarantee each and every obligation of Holdings and/or
AWA to a GE Entity, or to another party where nonperformance of such obligation
could impose an obligation on a GE Entity, existing under any transaction
between any GE Entity and Holdings and/or AWA or their respective affiliates
(the "AWA Obligations"), (y) Holdings and AWA shall guarantee each and every
obligation of Group and/or US Airways to a GE Entity, or to another party where
nonperformance of such obligation could impose an obligation on a GE Entity,
existing under any transaction between any GE Entity and Group and/or US Airways
or their respective affiliates (the "US Airways Obligations," together with the
AWA Obligations, the "Obligations"), and (z) to the extent a new holding company
is formed in connection with the Merger and survives the Merger ("Newco") it
shall guarantee all Obligations. Notwithstanding anything herein to the contrary
but without limiting the conditions for any Restructuring Transaction or the
effect of a Merger Event of Default or Global Event of Default, prior to the
Emergence Date and consummation of the Merger, (i) no default under, or failure
to perform, any US Airways Obligation or Restructuring Obligation by US Airways
or Group shall give rise to any obligation or liability of Holdings or AWA on
account of any such default under or failure to perform such US Airways
Obligation or Restructuring Obligation and (ii) no default under, or failure to
perform, any AWA Obligation or Restructuring Obligation by Holdings or AWA shall
give rise to any

                                       4
<PAGE>
obligation or liability of US Airways or Group on account of any such default
under or failure to perform such AWA Obligation or Restructuring Obligation.

debtor-in-possession ("DIP") lender and equity investor that is acceptable to
GECC and GEAE in terms of permitting disclosure of this Merger MOU and attached
Supplemental Merger Term Sheets or information contained herein or therein,
provided that such entities shall, in each case prior to disclosure, execute a

disclosing such summary, may be provided to (i) US Airways', Group's, Holdings'

This Merger MOU may not be modified or amended in any manner other than in
writing duly executed by or on behalf of all of the parties hereto.

Once this Merger MOU has been countersigned, the parties will proceed to

This Merger MOU shall be governed by and construed in accordance with the laws
of the State of New York, and may be executed in any number of counterparts,

counterparts together shall constitute and be one and the same instrument.

Exhibit A will be amended as described in Part I and II above. [REDACTED].

PART IV - RELATED SPARE ENGINE LEASE EARLY TERMINATIONS:

As a result of the fleet reductions noted above, and so long as US Airways

PART V - RELATED REDELIVERY CONDITION LEASE AMENDMENTS.

The applicable GE Entity and US Airways, or AWA and the applicable GE Entity,
will amend the leases for certain aircraft to provide for revised redelivery
conditions for the following aircraft that are to be removed pursuant to this
Exhibit A. The redelivery concession amendments in respect of US Airways
aircraft scheduled for redelivery prior to the Milestone Date for Emergence and
consummation of the Merger will be effective upon Emergence and consummation of
the Merger; it being understood that the relevant GE Entity will permit US
Airways to defer compliance with the applicable redelivery conditions to the
extent of such concession, and permit US Airways to calculate amounts owed to
the applicable lessor utilizing the concession (the obligation of US Airways to
pay such concession amount being deferred), until the Milestone Date for
Emergence and consummation of the Merger for aircraft scheduled for redelivery
prior thereto whereupon if Emergence and consummation of the Merger have not
occurred the deferred amounts shall be due and payable and if Emergence and
consummation of the Merger shall have occurred they shall be discharged. Except
as expressly provided below, all redelivery condition obligations detailed in
the respective leases shall otherwise remain in effect.

(1)  Anything herein to the contrary notwithstanding, AWA, but not US Airways,
     shall be entitled to realize any redelivery concessions, subject to the
     collective maximum aggregate amount of [REDACTED] thereof, associated with
     any AWA aircraft redelivered pursuant to Part III above.

Once such aggregate amount has been reached, then US Airways and/or AWA shall
pay and otherwise perform all redelivery requirements in full when due.
[REDACTED]. The redelivery concession amount is to be confirmed upon redelivery
of each applicable aircraft and a running total of the aggregate amount of the
redelivery concessions shall be maintained.

Prior to Emergence, any redelivery payments payable by any applicable GE Entity
to US Airways will first be netted against any redelivery payments payable to
any applicable GE Entity from US Airways, and, subject to the provisions of the
first paragraph of this Part V, any net balance remaining after such netting
will be refunded to US Airways upon Emergence and consummation of the Merger,
provided that there is no Merger Event of Default.

          Exhibit C hereto, have the right to remove from the CFM56-5 Agreement
          up to [REDACTED] Engines (comprised of [REDACTED] installed and,
          subject to compliance with the spare engine ratio requirements of the
          Agreement, [REDACTED] spare), identified by serial number in such
          Exhibit C. Reconciliation for Engines removed shall be determined as
          provided in the CFM56-5 Agreement. The parties agree that all removal
          credits owed by GEES to US Airways in connection with the Engines
          removed (in the approximate amount of [REDACTED]) shall be applied to
          reduce the outstanding balance of the Deferred Charges, in the amount
          of approximately [REDACTED], owing by US Airways to GEES under the
          CFM56-5 Agreement, which balance is further evidenced by US Airways'
          Term Note effective November 24, 2004.

     6.   GEES agrees that the Deferred Obligations (as defined in the initial
          Memorandum of Understanding among the parties thereto dated November
          24, 2004, as amended (the "Initial MOU")) in the amount of [REDACTED],
          owing to GEES by US Airways on the Petition Date, shall be reduced by
          [REDACTED], which represents the difference between (i) the payment
          received by GEES from the owner of ESN 722240 following US Airways'
          lease rejection and abandonment of the Engine in the Chapter 11 Case,
          and (ii) the not yet invoiced removal charge associated with such
          Engine (which shall be considered paid). The remaining balance of the
          Deferred Obligations, in the amount of [REDACTED], shall be paid in
          installments of [REDACTED] (and interest accrued thereon), due on June
          30, 2005, and [REDACTED] (and interest accrued thereon), due on the
          earlier of the effective date of the Chapter 11 Plan and September 30,
          2005.

     7.   Following expiration or earlier termination of the CF6-80C2 Agreement,
          GEES shall have the last right of offer with respect to any engine
          maintenance agreement for US Airways' CF6-80C2 fleet (whether operated
          by US Airways or in any combination with America West). In the event
          that GEES' proposal is competitive with proposals received by US
          Airways (or the merged airline) from vendors of comparable recognized
          reputation, then US Airways (or the merged airline) shall enter into
          an engine maintenance agreement with GEES for this fleet.

     8.   The CFM56-5 Agreement shall be extended to a term of [REDACTED] years,
          terminating [REDACTED], and US Airways shall waive its rights granted
          in Section 2.6 of Amendment No. 2 to the CFM56-5 Agreement, effective
          December 30, 2004, to convert to exclusive T&M or terminate the
          CFM56-5 Agreement on [REDACTED].

     9.   In lieu of the existing provisions contained in the CFM56-3 Agreement
          and the AWA Agreement governing minimum monthly payments, each of the
          Agreements shall be amended to provide that, for so long as both
          Agreements remain in effect, the minimum monthly payment on account of
          accrued Engine flight hours for the two Agreements together shall
          equal [REDACTED].

     10.  In consideration of the concessions offered by GEES and GEES--Dallas
          as set forth in this term sheet, US Airways, Group and America West
          agree that in the event that, following the Merger, they proceed to
          take delivery of up to [REDACTED] firm and [REDACTED] optional
          [REDACTED] aircraft from Airbus, all as contemplated in the integrated
          airframe/engine term sheet being entered into among US Airways, Group,
          America West and Airbus, the aircraft will be equipped with
          [REDACTED], provided that (i) the GE Parties supply to the merged
          airline a comprehensive product support package for the [REDACTED]
          aircraft for a new operator, including customary maintenance cost
          guarantees, product warranties, performance guarantees, retention
          guarantees and special guarantees, in each case as may be adjusted for
          the specific operating characteristics of the merged airline, and (ii)
          the GE Parties elect, at their option, to fund, arrange or guaranty
          long-term backstop secured debt financing for [REDACTED] of the Airbus
          order, as described herein (the "GE Financing"), with Airbus to be
          responsible for the remaining [REDACTED] share. Terms and conditions
          of the GE Financing will be substantially the same as contained in
          Airbus' backstop financing commitment on the date of the GE Parties'
          notice of election, pari passu. The GE Financing will be subject to a
          purchase price cap of [REDACTED] per [REDACTED] aircraft (2005 USD)
          and a purchase price cap of [REDACTED] per [REDACTED] aircraft (2005
          USD) with an escalation cap of [REDACTED] percent per annum to date of
          delivery and funding. For the sake of clarity, the GE Financing will
          not include any bridge financing, PDP financing or any other
          financing, with the sole exception of long-term take-out debt
          financing secured by the aircraft financed.

          The GE Parties' election to provide the GE Financing may be made in
          their sole discretion at any time prior to the date which is
          [REDACTED] months prior to the first day of the scheduled month of
          delivery of the first [REDACTED] aircraft under the Airbus order (the
          "Finance Notice Date"). The GE Parties' election will become effective
          only upon giving of written notice thereof. If the GE Parties elect to
          provide the GE Financing, then the GE Parties will be responsible for
          financing of the [REDACTED] firm [REDACTED] aircraft (and the GE
          Parties and Airbus will enter into a true-up agreement with Airbus
          with respect to the remaining two optional aircraft), but the GE
          Parties and Airbus may agree upon a different sharing relationship if
          necessary to achieve a [REDACTED] allocation.

          If the GE Parties do not elect to provide the GE Financing on or
          before the Finance Notice Date, then the merged airline will have the
          right to elect, in its sole discretion and on written notice delivered
          to the GE Parties within [REDACTED] days after the Finance Notice
          Date, to either (i) take delivery of the [REDACTED] aircraft under the
          Airbus order equipped with [REDACTED], without the GE Financing, or
          (ii) terminate the agreement with the GE Parties regarding the
          delivery of the [REDACTED] aircraft with [REDACTED], whereupon (and
          only upon delivery of the foregoing written notice) the combined
          airline will be free to enter into any agreement with an

                                      F-5
<PAGE>
          alternative provider of [REDACTED] incident to the Airbus order, with
          no further obligations to equip such [REDACTED] aircraft with
          [REDACTED].

          [REDACTED]

     11.  In consideration of the concessions offered by GEES and GEES--Dallas
          described in this term sheet, US Airways and Group agree that, in the
          event that Group assumes the [REDACTED] Purchase agreement dated as of
          [REDACTED], between [REDACTED] and Group, Group's pending order for
          the [REDACTED] aircraft provided for therein will be equipped with
          [REDACTED]. This paragraph is subject to the agreement of [REDACTED]
          (which shall be confirmed by the signature of [REDACTED] on this term
          sheet) that upon any extension of or delay in the delivery schedule
          for [REDACTED] family aircraft (the "[REDACTED] Aircraft") agreed to
          between Group and [REDACTED], the special allowance detailed in that
          certain Letter Agreement [REDACTED], between [REDACTED] and Group (the
          "GTA"), shall remain available to Group, as provided for in the GTA,
          upon delivery of each of such [REDACTED] Aircraft during such
          extension period, and that the [REDACTED] shall otherwise remain in
          full force and effect in accordance with the terms thereof.

     12.  Without prejudice to the respective obligations of GEES and
          GEES--Dallas under the Agreements, which shall at all times remain in
          full force and effect subject to their terms, the parties acknowledge
          that GEES and GEES--Dallas shall not be liable for compliance with
          engine return conditions provided for in any lease or other agreements
          of US Airways or America West with respect to Engines maintained under
          the Agreements.

     13.  The terms and conditions contained in this term sheet comprise a
          non-severable package of concessions and incentives, made and given in
          the context of the continuing agreements between the GE Parties and US
          Airways, Group or America West and/or their respective affiliates.
          Therefore, any default under any GE Obligation which is not excepted
          under paragraph 1(A) hereof, owed to, or affecting any guaranty of,
          those certain GE Parties comprised of General Electric Company, GE
          Transportation Component, and all affiliates of General Electric
          Company reporting to its GE Transportation Component ("GE
          Transportation Obligations") shall constitute a default under all
          other GE Transportation Obligations. Without limiting the rights and
          remedies of the GE Parties at law or in equity, upon the occurrence of
          any default with respect to the GE Transportation Obligations, all
          charges waived by GEES and GEES--Dallas under this term sheet, the
          outstanding balance of the Deferred Obligations, and the outstanding
          balance of the Deferred Charges under the CFM56-5 Agreement, as may be
          adjusted as provided herein, shall become immediately due and payable.

     14.  The parties hereto acknowledge that this term sheet and the exhibits
          annexed hereto and the Agreements contain commercially sensitive and
          proprietary information. Each of the parties agrees to keep this
          information strictly

                                       F-6
<PAGE>
          confidential and agrees to disclose it to no person other than: (A)
          their respective boards(s) of directors; (B) employees working on the
          subject matter of this term sheet; (C) professional advisors advising
          them concerning the subject matter of this term sheet provided that US
          Airways, Group, America West and such outside professional advisors
          execute, or have executed, a confidentiality agreement in form and
          substance acceptable to GEES and GEES--Dallas; (D) the ATSB, provided
          that US Airways and America West shall use commercially reasonable
          efforts to prevent disclosure of such information under the Freedom of
          Information Act; (E) the Bankruptcy Court during the course of the
          Chapter 11 Case, provided, however, that no document shall be filed
          with the Bankruptcy Court unless either there has been obtained prior
          to the filing thereof an order of the Bankruptcy Court enabling US
          Airways to file those portions of the documents under seal or portions
          of such filed documents designated by GEES and GEES--Dallas are
          redacted, in each case, as they shall request in their sole
          discretion; (F) the professional advisors of the Official Committee of
          Unsecured Creditors (the "Creditors Committee"), but only to the
          extent that designated portions of such material to be disclosed are
          redacted, in each case, as GEES and GEES--Dallas shall request in
          their sole discretion, and (G) any potential debtor-in-possession
          ("DIP") lender and equity investors provided that such entities shall,
          in each case prior to disclosure, execute a confidentiality agreement
          in form and substance acceptable to GEES and GEES--Dallas. A written
          summary of the transactions approved by GEES and GEES--Dallas in
          advance of disclosing such summary, may be provided to (i) US Airways'
          labor unions, (ii) any lender, potential lender, or participant, (iii)
          any material stakeholder in US Airways' proposed restructuring, (iv)
          the Creditors' Committee (but only if such summary has been redacted
          in a manner satisfactory to GEES and GEES--Dallas as provided above)
          or (v) such other third parties as the parties hereto may mutually
          agree; provided that such parties described in (i)-(v) above have
          executed a confidentiality agreement in form and substance acceptable
          to GEES and GEES--Dallas. The parties agree that the terms of this
          paragraph will survive any termination, through expiration or
          otherwise, of this term sheet.

     15.  Notwithstanding anything herein to the contrary, the agreement of each
          of US Airways, Group and America West to the modifications and
          amendments to the Agreements as set forth herein is subject to the
          satisfactory review of the US Airways Agreements by America West, and
          the AWA Agreements by US Airways, as applicable, prior to the approval
          of the MOU by the Bankruptcy Court, and, subject to paragraph 14
          hereof, GEES and GEES--Dallas shall reasonably cooperate with such
          parties in connection with such review process.

     16.  Anything herein to the contrary notwithstanding, the obligations of
          the applicable parties under each of paragraphs 2 and 6 hereof shall
          be immediately effective upon the approval of the MOU by the
          Bankruptcy Court as set forth herein, without regard to the other
          conditions precedent, as set forth in paragraph 1 hereof.

          which when so executed shall be deemed to be an original, and such
