                          REVISION:
          Atlantic Coast Airlines Revises Date for
            Second Quarter 2003 Earnings Release
      Changed to Wednesday, July 30rd at 2:00pm Eastern

Dulles,  VA, (July 21, 2003) - Atlantic Coast Airlines,  the
Dulles,  VA-based  regional carrier (ACA) (NASDAQ/NM:  ACAI)
today  announced that it has rescheduled its second  quarter
2003  earnings  release to Wednesday,  July  30th  from  the
previously  announced release date of Wednesday, July  23rd.
On July 30th at 2:00pm Eastern, the senior executives of the
company will conduct a live webcast.

The  Company has reached a tentative settlement with  United
Airlines regarding rates for 2003 service under its existing
United Express Agreement.  As a result, the Company requires
additional  time  to finalize and obtain approvals  for  the
tentative  settlement and has elected to delay its  earnings
release  by  one  week in order to properly incorporate  the
results  of the tentative settlement into its second quarter
2003  financial  results. The Company also  announced  today
that  it will not complete the retirement of all of its J-41
turboprop aircraft originally planned by December 31,  2003,
and  as  a result, intends to reverse, in its second quarter
results, the portion of the prior charges for the retirement
of those aircraft that will not be retired prior to year end
2003.

As  previously  announced, ACA and  United  have  also  been
engaged  in  discussions related  to  the  terms  of  a  new
agreement  to replace the existing United Express Agreements
between  the  parties.   Although  the  Company  and  United
continue to talk regarding proposed terms, the parties  have
not  reached  an  agreement  on terms  satisfactory  to  the
Company, and there can be no assurances that the Company and
United  will  reach such an agreement in  the  future.   The
Company  continues to develop contingency plans to allow  it
to  establish an alternative to the United business  in  the
event  that  satisfactory  arrangements  for  future  United
Express  service cannot be agreed with United.  The  Company
would  pursue such an alternative if it concludes  that  the
alternative offers more favorable prospects than offered  by
United.  The Company cannot predict the timing or outcome of
any  decision  by United with respect to the Company's  code
share arrangements.



The webcast will be hosted by:

   - Kerry Skeen, Chairman and Chief Executive Officer
   - Richard Surratt, Executive Vice President and Chief
  Financial Officer

Statements  in this press release and by Company  executives
regarding its implementation of new business strategies  and
its  relationship  with United Airlines, Inc.,  as  well  as
regarding   operations,  earnings,   revenues   and   costs,
represent  forward-looking information.  A number  of  risks
and uncertainties exist which could cause actual results  to
differ  materially from these projected results. Such  risks
and  uncertainties  include, among others:  United's  option
under  bankruptcy  rules to assume or  reject  the  existing
United  Express  Agreement, the  timing  of  such  decision,
efforts  by  United to negotiate changes prior to  making  a
decision  on  whether to affirm or reject the contract,  the
ability  and timing of agreeing upon rates with United,  the
effect  of  any  bankruptcy court review  of  the  tentative
agreement  on  2003  rates, and the fact  that  the  Company
cannot  predict  the timing or outcome of United's  decision
process or required approvals; the timing and impact on  the
Company's ability to implement an alternative business  plan
of  any  disengagement by the Company as  a  United  Express
carrier; the continued financial health of Delta Air  Lines,
Inc.;   the  ability  of  these  partners  to  manage  their
operations  and  cash flow, and ability and  willingness  of
these  partners to continue to deploy the Company's aircraft
and  to utilize and pay for scheduled service at agreed upon
rates;  general economic and industry conditions; additional
acts  of  war; and risks and uncertainties arising from  the
events of September 11, the impact of the outbreak of Severe
Acute  Respiratory  Syndrome on travel  and  from  the  slow
economy,  any of which may impact the Company, its  aircraft
manufacturers  and  its other suppliers  in  ways  that  the
Company is not currently able to predict.  Certain of  these
and  other risk factors are more fully disclosed under "Risk
Factors"  and  "Management's  Discussion  and  Analysis   of
Financial  Condition  and Results of Operations"  in  ACAI's
Annual  Report on Form 10-K for the year ended December  31,
2002 and in its Quarterly Report on Form 10-Q for the three-
month  period  ended March 31, 2003.  These  statements  are
made as of July 21, 2003 and ACA undertakes no obligation to
update  any  such forward-looking information, even  in  the
event  that  the  status  of  its negotiations  with  United
changes, or as a result of any other new information, future
events, changed expectations or otherwise.
