Item 9.   Regulation FD Disclosure.

On  May  19,  2004, Atlantic Coast Airlines Holdings, Inc.  (ACA)
(NASDAQ/NM:  ACAI)  issued  a  news  release  announcing  the  35
destinations that will be served by Independence Air's  new  low-
fare  flights  this  summer from Washington Dulles  International
Airport. The inaugural Independence Air flights will take off  on
June   16th,   with  new  service  to  East  Coast  and   Midwest
destinations  launching  throughout June,  July  and  August.  By
summer's  end,  the airline will offer 300 daily departures  from
Washington Dulles, making it the largest low-fare hub in America.

A  copy  of  the news release is attached as Exhibit 99  to  this
Current  Report  on  Form  8-K  and  is  incorporated  herein  by
reference.

Statements  in  this  press  release and  by  company  executives
regarding its implementation of new business strategies, as  well
as  regarding  operations, earnings, revenues and costs,  include
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:   the  ability of the  Company  to  implement  its
transition  out  of  the  United  Express  and  Delta  Connection
programs;  the  ability  to effectively  implement  its  low-fare
business  strategy utilizing regional jets and  Airbus  aircraft,
and  to  compete  effectively  as a low-fare  carrier,  including
passenger response to the Company's new service, and the response
of United or other competitors with respect to service levels and
fares  in  markets to be operated by the Company; the effects  of
high  fuel  prices  on  the Company; the  ability  of  government
agencies  involved in airport operations to handle the  increased
number  of  flights and passengers anticipated at Dulles  Airport
without  interference  with airline operations;  the  ability  to
complete the acquisition of, obtain certification for, and secure
financing  of, its Airbus aircraft, and to successfully integrate
these  aircraft into its fleet; the ability to redeploy or assign
to  Delta  or others the leases of the 328JET aircraft  currently
used   in   the   Company's  Delta  Connection  operations;   the
possibility  that  the Company will remain  obligated  under  the
leases for 328JET aircraft currently used in the Delta Connection
operations  even if assigned to Delta, and would be obligated  to
fulfill those obligations should Delta default at any time  prior
to  the  expiration of the leases; unexpected costs or procedural
complications  arising from the insolvency of  Fairchild  Dornier
GmbH,  the  manufacturer and equity owner  of  the  328JETs;  the
ability  to successfully remarket the J-41 aircraft; the  ability
to successfully hire and train employees in sufficient numbers to
implement  the  transition; the ability to reach  agreement  with
AMFA  and AFA-CWA on mutually satisfactory contracts; and general
economic  and  industry conditions, 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 the  Company's
Annual  Report on Form 10-K for the year ended December 31,  2003
and  in  its  Quarterly Report on Form 10-Q for the period  ended
March 31, 2004. These statements are made as of May 19, 2004  and
Atlantic  Coast Airlines Holdings, Inc. undertakes no  obligation
to  update any such forward-looking information, including  as  a
result   of   any   new  information,  future   events,   changed
expectations or otherwise.
