Dear Al:

     This letter, when countersigned by you, will constitute an agreement
between you and US Airways, Inc. ("US Airways") concerning supplemental
retirement benefits to be paid to you upon your retirement from US Airways. In
consideration for your future services, US Airways hereby agrees to pay you a
supplemental pension benefit in accordance with the following terms:

     1.   A pension benefit equal to the difference of subparagraph (a) minus
subparagraph (b), where (a) and (b) are:

          (a)  the pension benefit calculated under the benefit formula set
               forth in the Retirement Plan for Certain Employees of US Airways,
               Inc. (the "Retirement Plan") assuming (i) that the Retirement
               Plan had not been frozen in 1991, (ii) thirty years of "deemed"
               credited service under the Retirement Plan; (iii) final average
               earnings under the Retirement Plan using your base salary as of
               July 17, 2002 and assuming payment of a bonus under the US
               Airways Group, Inc. Incentive Compensation Plan at the "target"
               level, and (iv) no amendments to the Retirement Plan after the
               date hereof.

          (b)  all pension benefits payable to you in the aggregate under any
               defined benefit or defined contribution pension plan maintained
               by US Airways for the purpose of providing retirement income
               (including the Retirement Plan), whether tax-qualified or
               non-tax-qualified (the "Pension Plans").

     2.   For purposes of calculating the supplemental benefits under paragraph
1 above, the following rules will be applied:

          (a)  In determining the amount of the pension benefit calculated under
               the benefit formula set forth in the Retirement Plan it shall be
               assumed that the limitations imposed by Sections 401(a)(17) and
               415 of the Internal Revenue Code of 1986, as amended, are not
               applicable.

          (b)  In determining the amount of the pension benefit payable in the
               aggregate under those Pension Plans that are tax qualified and
               non-tax qualified defined contribution plans (the "Defined
               Contribution Pension Plans"), the benefit shall only be included
               to the extent that it is attributable to contributions made by
               US Airways (including earnings on such contributions) and any
               portion of the benefit payable under such Defined Contribution
               Pension Plans attributable to your own contributions (including
               earnings/losses on such contributions) shall be excluded.

          (c)  In determining the amount of the pension benefit payable under
               the Defined Contribution Pension Plans, any benefit payable in
               the form of a lump sum, shall be converted to an annuity for
               purposes of calculating the benefit to be offset by subparagraph
               1(b).

          (d)  In determining the amount of your supplemental benefit hereunder,
               the reduction factors, actuarial assumptions, definitions,
               administrative provisions and other applicable provisions of the
               Retirement Plan will control.

     3.   The amount of the supplemental pension benefit calculated pursuant to
paragraph 1 will be payable in an unreduced amount in the event of your normal
retirement from US Airways at age 65, or you may elect to receive early
retirement benefits under this agreement at any time after termination of your
employment with US Airways and upon your attainment of age 55. In the event of
your early retirement from US Airways, the supplemental pension benefit
calculated pursuant to paragraph 1 will be reduced for early commencement in
accordance with the early retirement reduction factors set forth in the
Retirement Plan.

     4.   You may elect to receive your supplemental pension benefits
(determined in accordance with paragraphs 1 and 6) in any one of the following
payment forms:

          (a)  an annuity (either single life or joint and survivor) payable
               from the general assets of US Airways; or

          (b)  a single lump sum payment.

In the event that you select the lump sum option, the cost of providing such
optional payment form must be cost-neutral to US Airways to providing a single
life annuity option and actuarial equivalencies will be determined in accordance
with the terms of the Retirement Plan, or if no such provision is included in
the Retirement Plan, determined in US Airways' sole discretion.

     5.   In the event of your death prior to the payment of your supplemental
pension benefit, your surviving spouse will be entitled to a benefit hereunder
equal to 50 percent of the benefit which would have been payable had you retired
and commenced benefits on the day before your death. In the event of your death
prior to the payment of your supplemental pension benefit and you have no
surviving spouse, US Airways will have no payment obligation under this
agreement. In the event of your death after the commencement of benefits
hereunder, a death benefit will be payable only if applicable pursuant to the
payment form elected under paragraph 4.

     6.   Notwithstanding anything in this agreement to the contrary, your
supplemental pension benefit will vest 10% on July 17, 2003 and an additional
10% on each of the nine succeeding anniversaries provided that you are actively
employed on the anniversary date, for an aggregate of 100% if you remain
employed by US Airways on July 17, 2012. Notwithstanding the foregoing, your
supplemental pension benefit will vest and you will be entitled to the entire
benefit under paragraph 1 if your employment terminates following a Change of
Control. For purposes of this paragraph, "Change of Control" shall have the
meaning set forth in the severance agreement between you and US Airways dated
June 26, 2002, as amended from time to time.

     7.   Your benefits hereunder shall be accrued, but unfunded and unsecured.

     8.   This letter may be amended or supplemented at the request of either
party hereto to clarify its application with respect to any future pension plan
which US Airways may adopt replacing or supplementing its existing plans. Any
such amendment or supplement will be prepared on the basis of the intent of the
parties that US Airways is seeking to provide you with supplemental pension
benefits as determined in paragraph 1 above.
