Mr. Jerrold A. Glass

Suite 700
Washington, DC 20036

Dear Jerry:

     We are pleased to offer you employment with US Airways, Inc. in the
position of Senior Vice President-Employee Relations. This letter outlines the
terms of US Airways' offer of employment. The terms of this offer will be
recommended to the Human Resources Committee of our Board of Directors for final
approval at the next Board meeting. Your start date will be as mutually agreed
to, but we would like it to be as soon as possible.

     Your position will report directly to David Siegel, the President and CEO,
and your annual base salary will be $385,000. In addition to your salary, you
will be eligible for incentive compensation pursuant to the terms of the
Incentive Compensation Plan ("ICP") and the Long-Term Incentive Plan ("LTIP")
for US Airways Group, Inc. Your target for the ICP will be 50 percent of your
base salary and may be increased for results in excess of the target up to a
maximum of 100 percent of base salary. Your target for the LTIP will be 70
percent of your base salary and may be increased for results in excess of the
target up to a maximum of 140 percent of base salary.

     We have agreed to guarantee your first year's ICP payment, in the amount of
50% of your base salary of record (a total of $192,500) to be paid to you as a
signing bonus within 30 days of your employment. If the ICP pays in excess of
the target amount for the 2002 fiscal year, you will be entitled to receive a
payment equal to the difference between the payout amount and the target amount
previously paid to you.

     We will also recommend to the Human Resources Committee that you receive a
grant of non-qualified stock options to buy 100,000 shares of US Airways Group,
Inc. Common Stock in accordance with the terms of the 1996 Stock Incentive Plan
of US Airways Group, Inc. ("1996 Stock Plan"). These options will be effective
on the date of your employment. The options will vest over a three-year schedule
with one-third vesting on the first anniversary of your employment and an
additional one-third vesting

on each of the subsequent two anniversary dates. The option price of these
shares will be based upon the average of the high and the low price of the stock
on the Composite Tape of the New York Stock Exchange on the date you begin
employment with the company or the date of the meeting of the Human Resources
Committee, whichever price is lower.

     Additionally, we will recommend that the Human Resources Committee approve
a restricted stock grant in the amount of 25,000 shares in accordance with the
terms of the 1996 Stock Plan. The restricted stock grant will also vest on a
three-year schedule with one-third of the restricted stock vesting on the first
anniversary of your employment and an additional one-third vesting on each of
the subsequent two anniversary dates.

     You will be eligible for medical, dental, life and disability insurance and
pension plan participation on the same basis as other US Airways officers. You
will be provided additional information on these benefit plans following your
employment with US Airways. In addition, we have agreed to provide you with a
supplemental executive retirement agreement ("SERP"). The SERP will provide you
with a pension benefit under the formula contained in the US Airways frozen
defined benefit pension plan for salaried employees which produces a benefit
equal of 65% of your final average earnings (base plus bonus) based on 30 years
of credited service. You will accrue credited service under the SERP at the rate
of two years of deemed credited service for each of the first five years of your
employment and one year of deemed credited service for each completed year after
the first five years of actual service. You will be immediately vested in the
SERP benefit as it accrues.

     Essentially, the formula for accrual of benefits in the defined benefit
plan is 2.4% of final average earnings for each year of service up to 25 years
and 1% of final average earnings for each of the next 5 years, offset by Social
Security benefits. Benefits under the SERP will be based upon your actual salary
and deemed ICP target bonus of 50% of salary and will be calculated in
accordance with the terms of the frozen defined benefit plan. The amount paid
under the SERP will be offset by other Company provided pension benefits.
Benefits payable under the SERP will be accrued but unfunded and unsecured and
are payable from the general assets of US Airways.

     US Airways also offers you and your eligible family members on-line first
class, positive space travel privileges for business and pleasure for a small
annual fee. The Internal Revenue Service requires that you receive imputed
income for positive space non-business travel and that you pay taxes on such
income. US Airways' officer benefit package provides a gross-up payment (up to a
maximum of $10,000) to cover your tax liability resulting from travel. In
addition, you and your eligible family members will have free access to
US Airways Club facilities.

     You will be eligible to receive lifetime officer travel benefits upon the
completion of five years of service with US Airways.

     As an officer of US Airways, you will also receive an employment agreement
providing you with certain benefits in the event that your employment is
terminated or substantially changed either prior to a change in ownership of the
company or following a change of control. If your employment is terminated or
substantially changed prior to a change in control, you will receive a severance
benefit equal to two years' base salary and target bonus. In the event that your
employment is terminated or substantially changed after a change in control, you
will receive a severance benefit equal to three years' base salary and target
bonus, three years of benefit continuation, three years of LTIP payout and life
time officer travel benefits.

     The preceding paragraphs describe US Airways' current officer benefit
programs. These programs may be changed from time to time or terminated at
management's discretion.

     US Airways requires all prospective employees to submit to drug testing
prior to the establishment of an employment relationship. You will be contacted
by US Airways' Medical Affairs department to arrange a testing time and
location. Your employment is contingent upon successful completion of the drug
test.

     Enclosed are two copies of this letter. Please countersign the letters in
the space provided for your signature and return one copy to me as soon as
possible. Please keep one copy for your records.

                                              Sincerely,

                                              Michelle V. Bryan
