       Atlantic Coast Airlines Holdings, Inc. Reports
     Second Quarter 2004 Financial and Operating Results

Dulles,  VA,  (July  28,  2004) -  Atlantic  Coast  Airlines
Holdings,  Inc. (Nasdaq/NM: ACAI), parent of Atlantic  Coast
Airlines (ACA) and Independence Air, today reported a second
quarter  2004 net loss of $27.1 million (($0.60) per diluted
share)  compared to second quarter 2003 net income of $45.7
million  ($1.01  per  diluted  share)  in  accordance with
Generally   Accepted  Accounting  Principles  (GAAP).  The
company's  results for second quarter 2004 and 2003 reflect
several special items as noted below and in the Pro-Forma
Financial Results table at the end of this press release.
The  company's net loss for second quarter 2004 includes:

- --$21.9 million (pre-tax) charge for the early retirement of
ten leased Jetstream-41 (J-41) turboprop aircraft
- --$3.6  million (pre-tax) impairment charges to write-down
the  value  of  one owned 328JET aircraft and certain J-41
expendable parts inventory to current estimated fair market
value

Excluding  the charges and credits, the company reported  a
net loss of $11.4  million or ($0.25) per diluted share
compared to net income of $17.2 million or $0.38 per diluted
share  in  the  second  quarter 2003.  A  reconciliation  of
results  as  reported in accordance with GAAP to these  non-
GAAP  presentations for the three and six months ended  June
30,  2004  and  2003 is included in the Pro-Forma  Financial
Results table at the end of this press release.

Results for the second quarter were impacted by the start of
the  transition to Independence Air. Results reflect reduced
revenue  as  aircraft  exited the company's  United  Express
program  commencing  June  4,  2004  and  were  phased  into
Independence Air service commencing June 16, 2004,  as  well
as increased sales and marketing expense associated with the
Independence  Air operations.  In addition,  second  quarter
results were impacted by the following items:

- --$1.1  million United revenue dispute-United withheld  $1.1
million  from  payments due in June.  The  company  believes
these  payments  were  required under  its  agreements  with
United  and has filed a motion with the bankruptcy court  to
collect this amount.
- --$1 million for CRJ painting expense
- --$1  million  reserve for an FAA fine previously  disclosed
and  for  a  potential  liability associated  with  a  prior
grievance filed under the company's labor agreements

The  company's  exit from the United Express  program  as  a
result of United's decision to reject its agreement with ACA
is  nearly complete, with the transfer of the last  aircraft
and stations out of the United Express program scheduled for
August  3, 2004.  Once flights have been completed  on  that
date, the company will no longer operate in partnership with
United,  and ACA's remaining 26 United Express CRJs will  be
released and undergo interior and exterior upgrades prior to
entering service for Independence Air.

The  five  J-41  turboprops currently in the United  Express
program  will  be immediately retired, leaving  the  company
with a modern all-jet fleet.

In  addition,  the company is working on a  transition  plan
with  Delta Air Lines to exit the company's Delta Connection
agreement. Following the decision by Delta to terminate  the
agreement without cause, the company exercised its right  in
July to require Delta to assume  the leases on 30 of the 33
328JETs that are used  in the   Delta  Connection  operation.
The  company  currently anticipates  that  it  will  finish
service  in  the  Delta Connection program and transfer 30 of
its 328JET aircraft to Delta by November 2, 2004.

On  June 16, 2004, the company began new low-fare service as
Independence   Air  from  Washington  Dulles   International
Airport.  To date, new service and market launches  continue
as  scheduled.  Independence Air now has 56 jet aircraft  in
service, while the upgrade process for the remaining 31 jets
remains  on  or ahead of schedule.  Two-thirds  of  the  "A"
concourse   at   Dulles-constituting  24  aircraft   parking
positions-has   been  upgraded  for  the  Independence   Air
operation,  with  the final one-third  to  be  converted  in
August.   Eight more gates in the "B" concourse designed  to
handle A319 service will come online beginning in the fourth
quarter   of  this  year.  Service  currently  exists   from
Washington Dulles to 22 markets, with additional flights  to
the  following destinations scheduled to commence or  expand
in the coming weeks:

August  1:  New York/JFK (13 daily roundtrips, expanding  to
17  on  8/4), Greensboro (9 daily roundtrips), Cleveland  (9
daily roundtrips),   Savannah/Hilton   Head   (6 daily
roundtrips), Atlanta (expands from 8 daily roundtrips to 16)

August 15:  Hartford (8 daily roundtrips), Columbus (8 daily
roundtrips),  Dayton (8 daily roundtrips),  Indianapolis  (7
daily roundtrips)

August  23:   Detroit  (8 daily roundtrips),  Pittsburgh  (8
daily   roundtrips),   Providence  (8   daily   roundtrips),
Louisville (6 daily roundtrips), Jacksonville (expands  from
6 daily roundtrips to 7)

September 1:  Stewart/Newburgh (6 daily roundtrips)

By  September  1, 2004, the Independence Air  schedule  will
grow   to  600  daily  departures,  and  its  operation   at
Washington  Dulles will be the largest low-fare hub  in  the
United States in terms of number of departures.

Prior  to  the  opening of trading on August  4,  2004,  the
company  will  change the name of its corporate  parent  and
stock   ticker   symbol   to  reflect  its   newly-premiered
Independence Air brand name.  Parent company Atlantic  Coast
Airlines  Holdings,  Inc. will become  FLYi,  Inc.  and  its
symbol  on the Nasdaq National Market will change from  ACAI
to   FLYI,  mirroring  the  Independence  Air  web   address
www.FLYi.com. Current shareholders will not need to take any
action as a result of this change. The operating entity will
continue  to  operate  as  Atlantic Coast  Airlines  through
November  2,  2004,  at which time it  will  be  changed  to
Independence  Air,  Inc.  and the  company's  FAA  operating
certificate will reflect that identity.

Independence  Air  will  begin  adding  27  brand  new  132-
passenger Airbus A319s at Washington Dulles this fall.   The
Airbus  aircraft--scheduled to  launch  in  November--  will
allow  Independence Air to offer low-fare  service  non-stop
from  Washington  to  major  destinations  in  Florida,  the
Midwest   and   across  the  country  to  the  West   Coast.
Independence  Air plans to add live satellite  TV  or  other
programming  in every seatback of its Airbus aircraft  early
next year.

The  company employs over 4,200 aviation professionals.  For

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
competitors  with  respect to service levels  and  fares  in
markets  served  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 Washington
Dulles  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 implement its assignment 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 anticipated to be assigned to Delta, and would be
obligated to fulfill these 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 July 28, 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.

Notes to Pro-Forma Financial Results:
The  company's Pro-Forma Financial Results present  non-GAAP
financial  measures  that  the  company  uses  for  internal
managerial  purposes,  when publicly providing  guidance  on
possible future results, and as a means to evaluate  period-
to-period comparisons. These non-GAAP financial measures are
used   in  addition  to  and  in  conjunction  with  results
presented in accordance with GAAP, and should not be  relied
upon to the exclusion of GAAP financial measures. These non-
GAAP financial measures reflect an additional way of viewing
aspects  of our operations that, when viewed with  our  GAAP
results    and    the   accompanying   reconciliations    to
corresponding GAAP financial measures, provide a more
complete understanding of factors and trends affecting our
business. Management strongly encourages  investors  to
review the company's financial statements and publicly-filed
reports  in  their entirety and to not rely  on  any  single
financial measure.

With  respect to the specific matters addressed in the  Pro-
Forma  Financial  Results,  the  company  has  excluded  the
following items for the reasons addressed below:

- --J-41   retirement  charges  and  reversals:   The  company
excludes for pro forma results charges and credits, if  any,
associated  with the retirement of aircraft from its  fleet.
These  amounts  typically represent the  expense  of  future
commitments,  and  are not considered by  management  to  be
indicative  of  current period operations.  Under  Financial
Accounting  Standards Board Statement No.  146,  "Accounting
for  Costs  Associated  with Exit or  Disposal  Activities,"
which the company adopted on January 1 2003, liabilities for
the  costs  associated  with  retirement  of  the  company's
remaining J-41s will be recognized when the liabilities  are
incurred. Reversals or earlier non-cash charges occurred  in
2003  when  the company revised J-41 retirement  plans  that
were   established  prior  to  the  company's  adoption   of
Statement No. 146.

- --Impairment  losses  for  owned 328JET  aircraft  and  J-41
expendable  parts  inventory:   Under  Financial  Accounting
Standards  Board  Statement No.  144,  "Accounting  for  the
Impairment  or  Disposal of Long-Lived  Assets,"  impairment
exists  when  the  carrying amount  of  a  long-lived  asset
exceeds its fair value and the carrying amount of the  asset
is not recoverable if it exceeds the sum of the undiscounted
cash  flows  expected to result from the use and disposition
of  the  asset.  Once an impairment loss is recognized,  the
adjusted carrying amount of the long-lived asset establishes
a new cost basis.

- --Government compensation: The government payments are based
on  special  legislation for specific areas  for  which  the
government  has determined to provide benefits to  airlines.
These  payments are not treated as operating income  in  the
company's  financial statements and are  not  considered  by
management when evaluating the company's performance.

- --Portions of the rate settlement with United in the  second
quarter  2003  related to a previous  period:   The  company
records its revenue based on fee per departure rates paid by
its   partners,  which  rates  are  subject  to   adjustment
annually. When rates are not agreed as of the completion  of
a  given period, the company records its revenue based on an
estimate of the rates. Upon agreement on rates, the  company
records, in the period rates are agreed, adjustments for the
estimates  made  for the prior periods. Management  believes
that  the adjustments for the impact of changes to estimates
provide    additional   information   for   period-to-period
comparisons of operating performance.
