                 ATLANTIC COAST AIRLINES HOLDINGS, INC.
           NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                               (Unaudited)


1.  BASIS OF PRESENTATION

The  accompanying  unaudited condensed consolidated financial  statements
include  the accounts of Atlantic Coast Airlines Holdings, Inc.  ("ACAI")
and  its  wholly-owned subsidiaries, Atlantic Coast Airlines ("ACA")  and
Atlantic  Coast  Jet, Inc. ("ACJet"), (together, the "Company"),  without
audit,  pursuant  to  the rules and regulations  of  the  Securities  and
Exchange  Commission.   The  information  furnished  in  these  unaudited
condensed  consolidated  financial statements includes  normal  recurring
adjustments  and reflects all adjustments which are, in  the  opinion  of
management,  necessary  for  a  fair presentation  of  such  consolidated
financial  statements. Results of operations for the  three-month  period
presented  are not necessarily indicative of the results to  be  expected
for  the  full  year  ending  December  31,  2001.   Certain  amounts  as
previously reported have been reclassified to conform to the current year
presentation.   Certain  information and  footnote  disclosures  normally
included  in the consolidated financial statements prepared in accordance
with  accounting  principles generally accepted in the United  States  of
America  have  been  condensed or omitted  pursuant  to  such  rules  and
regulations,  although  the Company believes  that  the  disclosures  are
adequate  to  make  the  information  presented  not  misleading.   These
condensed consolidated financial statements should be read in conjunction
with  the  consolidated  financial statements,  and  the  notes  thereto,
included  in the Company's Annual Report on Form 10-K for the year  ended
December 31, 2000.

2.  OTHER COMMITMENTS

The  Company  has  periodically entered into a series  of  put  and  call
contracts  as  an interest rate hedge designed to limit its  exposure  to
interest  rate changes on the anticipated issuance of permanent financing
relating  to the delivery of the Canadair Regional Jet ("CRJ")  aircraft.
On  July  6,  2000  the  Company entered into six interest  rate  forward
transactions maturing between August 2000 and January 2001 as an interest
rate  hedge  relating to the delivery of six aircraft. These transactions
settled  shortly before the aircraft were scheduled to be  delivered  and
had an aggregate notional value of $51 million.  The Company settled five
of  the  six  interest  rate forward transactions  in  2000.   The  sixth
interest  rate  forward transaction settled January 3, 2001,  and  had  a
notional  value  of  $8.5  million,  resulting  in  a  payment   to   the
counterparty of $722,000.

In  February  1999,  the  Company  entered into  an  asset-based  lending
agreement with two financial institutions that provided the Company  with
a  line  of  credit  for up to $35 million depending  on  the  amount  of
assigned ticket receivables and the value of certain rotable spare parts.
With   the  change  in  the  United  Express  agreement  from  a  prorate
arrangement   to   a   fee-per-departure/payment-in-advance   arrangement
effective December 1, 2000, the Company's ticket receivable available for
assignment  has  been reduced to zero.  As such, the available  borrowing
under  the  line  of credit was limited to the value of  certain  rotable
spare  parts,  to a maximum of $8.0 million.  On May 2, 2001  the  asset-
based lending agreement was amended to add an additional $8.4 million  to
the  borrowing base, collateralized by the value of certain fixed assets.
The line of credit will expire on September 30, 2001, or upon termination
of  the United Express agreement, whichever is sooner.  The interest rate
on this line is LIBOR plus .75% to 1.75% depending on the Company's fixed
charges coverage ratio.  There were no borrowings on the line during 2000
or  to  date  in 2001.  As of May 2, 2001, the Company has pledged  $15.6
million of this line of credit as collateral for letters of credit issued
on  behalf  of the Company by a financial institution.  This  effectively
commits  most  of the line of credit.  The Company anticipates  replacing
this  existing  line of credit on or before September 30, 2001  when  the
current line expires.

As of March 31, 2001, the Company had firm orders for 54 CRJs in addition
to  the 42 previously delivered, and options for 80 additional CRJs.  The
Company  also  had  42  Fairchild Dornier 328JET  regional  jet  aircraft
("328JET")  on  firm order in addition to the 20 already  delivered,  and
held options for an additional 83 aircraft.  The future delivery schedule
of  the  remaining 96 firm ordered regional jet aircraft as of March  31,
2001  is  as  follows: 24 aircraft are scheduled for delivery during  the
remainder of 2001, 30 aircraft in 2002, and 42 aircraft in 2003.

On  March 2, 2001, the Company announced it has entered into an agreement
with  UAL  Corporation  ("UAL"),  parent of  United,  to  acquire-through
subsidiaries-the three regional airlines that are currently  wholly-owned
by  US  Airways  Group,  Inc.  ("US Airways").  The  three  carriers  are
Allegheny  Airlines, Piedmont Airlines and PSA Airlines. Closing  of  the
acquisition from US Airways, which is contingent upon and would occur  at
the  same  time as closing of the proposed United/US Airways  merger,  is
subject  to regulatory approvals and to termination rights by  UAL.   The
aggregate  purchase price for the three carriers, initially set  at  $200
million, will be paid at closing in the form of a promissory note due  in
18  months. Under the terms of the agreement, the Company will not  remit
principal  or interest payments or accrue interest on the note until  and
if  an  agreement  on an ultimate purchase price for each  of  the  three
regional  carriers  is finalized.  The ultimate purchase  price  will  be
negotiated during the 18-month term of the promissory note.  If agreement
cannot  be reached on an ultimate purchase price as to any or all of  the
three  carriers,  the  Company's acquisition  of  that  carrier  will  be
unwound.   The  ultimate  purchase price paid by  the  Company  may  vary
substantially from the amount of the promissory note, and there can be no
assurances that the Company will retain any or all of the three carriers.
If  closing occurs on the initial purchase of the three carriers but ACAI
is  not  the  ultimate  purchaser of at least one of  the  carriers,  the
Company  will  receive  a  fee of up to $10.5  million.  The  results  of
operations, and any capital requirements of the three regional  carriers,
are not expected to contribute to the Company's results of operations  or
impact its financial position until and if an ultimate purchase price  is
agreed to and the acquisition can no longer be unwound.

3.  ADOPTION OF FASB STATEMENT 133

In  June  1998,  the  FASB  issued Statement  No.  133,  "Accounting  for
Derivative   Instruments   and   Hedging  Activities."   This   Statement
establishes accounting and reporting standards for derivative instruments
and  all  hedging activities.  It requires that an entity  recognize  all
derivatives  as  either  assets  or liabilities  at  their  fair  values.
Accounting for changes in the fair value of a derivative depends  on  its
designation and effectiveness.  For derivatives that qualify as effective
hedges,  the  change in fair value will have no impact on earnings  until
the   hedged  item  affects  earnings.   For  derivatives  that  are  not
designated as hedging instruments, and for the ineffective portion  of  a
hedging  instrument, the change in fair value will affect current  period
earnings.

The  Company  adopted Statement No. 133 effective January 1,  2001.   The
impact  of adopting this statement has not had a material impact  on  the
Company's  financial  position or results of  operations  for  the  first
quarter of 2001.

4.  INCOME TAXES

The  Company's effective tax rate for federal and state income taxes  was
40% for the first quarter of 2001 and 2000.

5.  INCOME PER SHARE

Basic income per share is computed by dividing net income by the weighted
average number of common shares outstanding.  Diluted income per share is
computed by dividing net income by the weighted average number of  common
shares  outstanding and common stock equivalents, which consist of shares
subject  to  stock options computed using the treasury stock method.   In
addition,  under the if-converted method, dilutive convertible securities
are  included in the denominator while related interest expense,  net  of
tax, for convertible debt is added to the numerator. A reconciliation  of
the  numerator and denominator used in computing basic and diluted income
per share is as follows:

6.  AIRCRAFT EARLY RETIREMENT CHARGE

During 2000,  the  Company  began    retiring     early  the  leased  19-
seat  British Aerospace J-32 turboprop ("J-32") aircraft from the  fleet.
As of May 1, 2001, 14 J-32s had been removed from service.  The remaining
14  J-32s will be removed from service during the remainder of 2001.  The
early  retirement of the 28 leased J-32 aircraft resulted in the  Company
recording  a  $29.0 million (pre-tax) restructuring charge  during  2000.
During March 2001, the Company reached agreement with the lessor for  the
early  return and lease termination of all of the J-32's and as a  result
paid  a  lease termination fee which consisted of $19.1 million in  cash,
and  the application of $5.2 million in credits due from the lessor.  The
Company  believes that the remainder of the accrual will be  adequate  to
provide  for costs necessary to meet aircraft return conditions and  does
not expect to incur any additional charges against earnings for the early
retirement of the J-32 fleet.

Results of Operations

     Forward Looking Statements

           The  following  Management's Discussion and Analysis  contains
forward-looking statements and information that are based on management's
current  expectations as of the date of this document. When used  herein,
the  words  "anticipate", "believe", "estimate" and "expect" and  similar
expressions, as they relate to the Company's management, are intended  to
identify   such   forward-looking   statements.    Such   forward-looking
statements  are  subject to risks, uncertainties, assumptions  and  other
factors that may cause the actual results of the Company to be materially
different  from  those  reflected  in  such  forward-looking  statements.
Factors  that  could  cause  the  Company's  future  results  to   differ
materially  from the expectations described here include the  ability  of
the  Company  to obtain favorable financing terms for its  aircraft,  the
ability  of  the aircraft manufacturers to deliver aircraft on  schedule,
unexpected  costs  or delays in the implementation of  new  service,  the
ability  of  the  Company to successfully retire the Company's  turboprop
fleet,  the ability to hire and retain employees, the weather, the impact
of  labor issues or strikes at United Airlines, Inc. or Delta Air  Lines,
Inc.  on  those  companies'  utilization and  support  of  the  Company's
operations,  airport and airspace congestion, changes in and satisfaction
of  regulatory  requirements  including requirements  relating  to  fleet
expansion,  general  economic and industry conditions,  and  the  factors
discussed below and in the Company's Annual Report on Form 10-K  for  the
year  ended December 31, 2000.  A number of risks and uncertainties exist
with  regard  to  the  Company's agreement with UAL Corporation  ("UAL"),
parent   of  United  Airlines,  Inc.  ("United")  to  acquire  -  through
subsidiaries  -  the three regional airlines that are  currently  wholly-
owned  by US Airways Group, Inc. ("US Airways") which could cause  actual
results  to differ materially from these projected results. Such  factors
relating  to  the  transaction include, among others,  UAL's  termination
rights,  ability  to  reach agreement with UAL on the  ultimate  purchase
price,  ability  to  obtain  regulatory  approval  with  respect  to  the
transaction,   financing  of  the  final  purchase  price,  unanticipated
unreimbursed  costs, ability of the three companies to operate  as  fully
independent  corporations, ability to resolve any conflicting  provisions
in  collective bargaining agreements obligating any company  involved  in
the   transaction,   potential   turboprop   fleet   transition   issues,
satisfactory resolution of amendable union contracts, operational  issues
involving  any  of  the  three airlines, and  the  impact  of  these  new
operations on existing operations.  The Company does not intend to update
these  forward-looking statements prior to its next required filing  with
the Securities and Exchange Commission.

     General

          In  the first quarter of 2001, the Company posted net income of
$9.6 million, compared to income of $2.3 million for the first quarter of
2000.   Operating income for the three months ended March  31,  2001  was
$15.5  million  as  compared to $4.5 million for the three  months  ended
March 31, 2000.  Unit revenues, revenue per ASM ("RASM"), increased  1.6%
to  19.1  cents,  while  unit  costs, operating  cost  per  ASM  ("CASM")
decreased  6.0% to 17.1 cents compared to the first quarter  2000.   This
resulted in operating margin increasing to 11.6% for the first quarter of
2001 from 4.9% for the first quarter of 2000.  Total passengers increased
22.4% in the first quarter of 2001 to 937,698 passengers, compared to the
first quarter of 2000.

     Operating Revenues

           The  Company's  operating revenues increased 44.3%  to  $133.5
million  in  the first quarter of 2001 compared to $92.5 million  in  the
first  quarter of 2000.  The increase resulted from a 42.8%  increase  in
ASMs  to  689,540 in the first quarter of 2001 from 482,832 in the  first
quarter of 2000, as well as a 27.7% increase in the revenue per departure
to  $2,487 in the first quarter of 2001 from $1,948 in the first  quarter
of  2000.   Revenues for the first quarter of 2001 were recognized  under
fee-per-departure agreements as compared to a proration of fare agreement
for  revenues for the first quarter of 2000.  Whereas quarterly  revenues
under  a  proration  of  fare agreement normally reflected  seasonal  and
passenger  demand trends, with lower revenue during the first and  fourth
quarters and higher revenue during the second and third quarters, fee-per-
departure  agreements generally minimize seasonality effects on  revenue.
Quarterly   comparison  of  revenue  per  departure  for   2001  to  2000
results  will  in  part  reflect this reversal of historical  seasonality
trends.   Therefore,  the revenue per departure  increase  in  the  first
quarter  of  2001  is not necessarily indicative of  the  results  to  be
expected for other quarters, or the full year ending December 31, 2001.

          The  increase in capacity as measured in ASMs is the result  of
service  expansion  utilizing additional 50 seat  Canadair  Regional  Jet
("CRJs"),  and  the  addition  of  20 32 seat  Fairchild  Dornier  328JET
("328JET")  aircraft, partially offset by the removal of  eleven  British
Aerospace J-32 Turboprop ("J-32") aircraft.  The Company was operating 42
CRJs as of March 31, 2001 as compared to 26 as of March 31, 2000.  The 20
328JET aircraft were placed in revenue service beginning during the third
quarter of 2000, continuing through the first quarter of 2001.

     Operating Expenses

           The  Company's operating expenses increased 34.1% in the first
quarter of 2001 compared to the first quarter of 2000 due primarily to: a
55.8% increase in total fuel costs as a result of a 2.6% increase in  the
average  price per gallon of jet fuel, coupled with a 23.7%  increase  in
the  average fuel burn rate to 255 gallons per hour; a 42.8% increase  in
ASMs;  and a 58.8% increase in aircraft rental expense, all partly offset
by  a  70.8%  decrease  in traffic commissions  and  related  fees.   The
increase  in  ASMs,  fuel  burn rate, and aircraft  rental  reflects  the
addition  of 16 CRJs and 20 328JETs into scheduled service,  net  of  the
early  retirement of eleven J32s, since the end of the first  quarter  of
2000.   A  summary  of  operating expenses as a percentage  of  operating
revenues and cost per ASM for the three months ended March 31, 2000,  and
2001 is as follows:

           Cost per ASM decreased 6.0% on a year-over-year basis to  17.1
cents  during the first quarter of 2001 primarily due to a 42.8% increase
in  ASMs  and  a 70.8% decrease in the year-over-year traffic commissions
and  related fees.  Many of these fees are no longer borne by the Company
as  a  result  of the restatement of the United Express agreement,  which
went into effect on December 1, 2000.  Under  the restated agreement, the
Company  is  responsible  for  fees associated  with  the  major  airline
Computer Reservation Systems.

           Salaries and related costs per ASM increased 6.0% to 5.3 cents
in  the  first quarter of 2001 compared to 5.0 cents in the first quarter
of 2000.  In absolute dollars, salaries and related costs increased 52.5%
from  $24.3 million in the first quarter of 2000 to $37.0 million in  the
first  quarter of 2001. The increase resulted primarily from the addition
of  790  full  and  part time employees to support the  36  regional  jet
aircraft added during 2000 and 2001.

          The cost per ASM of aircraft fuel increased to 3.0 cents in the
first quarter of 2001 compared to 2.7 cents in the first quarter of 2000.
In  absolute  dollars, aircraft fuel expense increased 55.8%  from  $13.1
million  in  the  first  quarter of 2000 to $20.5 million  in  the  first
quarter of 2001. The increased fuel expense resulted from a 2.6% increase
in  the  average cost per gallon of fuel from $1.058 to $1.085,  a  22.8%
increase  in  block hours, and the higher fuel consumption  per  hour  of
regional jet aircraft versus turboprop aircraft which resulted in a 23.7%
increase  in  the system average burn rate (gallons used per  block  hour
flown).

           The  cost  per  ASM  of  aircraft  maintenance  and  materials
decreased to 1.6 cents in the first quarter of 2001 compared to 1.7 cents
in  the first quarter of 2000.  In absolute dollars, aircraft maintenance
and  materials  expense increased 38.2% from $8.1 million  in  the  first
quarter  of  2000  to  $11.2 million in the first quarter  of  2001.  The
increased  expense resulted from the increase in the size  of  the  total
fleet,  the gradual expiration of manufacturer's warranties on  the  CRJs
and  resulting  addition of the aircraft under the Company's  maintenance
agreement with GE, and the continual increase in the average age  of  the
turboprop fleet.

          The cost per ASM of aircraft rentals increased to 2.9 cents  in
the  first quarter of 2001 compared to 2.6 cents in the first quarter  of
2000.   In absolute dollars, aircraft rentals increased 58.8% from  $12.7
million  in  the  first  quarter of 2000 to $20.2 million  in  the  first
quarter  of  2001,  reflecting the addition of sixteen CRJ  aircraft  and
twenty 328JET aircraft since March 31, 2000, net of the removal of 11  J-
32 turboprop aircraft.

           The  cost  per  ASM of traffic commissions  and  related  fees
decreased  78.6% to 0.6 cents for the first quarter of 2001  compared  to
2.8  cents for the first quarter of 2000.   In absolute dollars,  traffic
commissions  and related fees decreased 70.8% from $13.2 million  in  the
first quarter of 2000 to $3.9 million in the first quarter of 2001.  Many
of  these  fees  are no longer borne by the Company as a  result  of  the
restatement of the United Express agreement, which  went into  effect  on
December  1,  2000.   Under  the  restated  agreement,  the  Company   is
responsible   for  fees  associated  with  the  major  airline   Computer
Reservation Systems, while traffic commissions are borne by United.

          The  cost  per ASM of facility rents and landing fees increased
22.2%  from 0.9 cents for the first quarter of 2000 to 1.1 cents for  the
first  quarter of 2001.  In absolute dollars, facility rents and  landing
fees  increased 66.3% from $4.5 million in the first quarter of  2000  to
$7.4  million  in  the first quarter of 2001.  The increase  in  absolute
dollars for facility rents and landing fees is a result of a 14% increase
in number of departures, the heavier landing weight of the regional jets,
and  the  Company's occupation of its new corporate headquarters building
as of December 1, 2000.

           The cost per ASM of depreciation and amortization remained the
same at 0.5 cents for the first quarter of 2001 and the first quarter  of
2000.  In absolute dollars, depreciation and amortization increased 31.7%
from  $2.6  million in the first quarter of 2000 to $3.4 million  in  the
first  quarter of 2001 primarily as a result of additional rotable  spare
parts associated with the regional jets.

           The cost per ASM of other operating expenses increased to  2.1
cents in the first quarter of 2001 from 2.0 cents in the first quarter of
2000.  In absolute dollars, other operating expenses increased 52.6% from
$9.5  million in the first quarter of 2000 to $14.5 million in the  first
quarter  of  2001.   The increased costs result primarily  from  training
expenses for new flight crews to support additional aircraft.

           As a result of the foregoing changes in operating expenses and
a  42.8% increase in ASMs, total cost per ASM decreased to 17.1 cents  in
the first quarter of 2001 compared to 18.2 cents in the first quarter  of
2000.  In absolute dollars, total operating expenses increased 34.1% from
$88.0 million in the first quarter of 2000 to $118.0 million in the first
quarter of 2001.

          The  Company's effective tax rate for federal and state  income
taxes was 40% for the first quarter of 2001 and 2000.

Outlook

          This  outlook section contains forward-looking statements which
are  subject to the risks and uncertainties set forth in the MD&A section
under Forward Looking Statements.

          As  of  May 1, 2001, the Company was operating a fleet  of  110
aircraft  comprised of 43 CRJs, 21 328JETs, 32 J41s  and  14  J32s.   The
Company  does not expect to incur any additional charges against earnings
for the early retirement in 2001 of the remaining 14 J-32 aircraft in the
fleet.

          The  Company  is evaluating plans to early retire the  32  J-41
turboprop aircraft from its fleet beginning in 2002.  Adoption of a  plan
to  retire  the J-41 turboprop fleet likely will result in a  substantial
charge  to  future  earnings.  The Company is  unable  at  this  time  to
quantify  the amount of any such retirement charge, as a formal plan  has
not yet been adopted.

          As  of May 1, 2001, the Company had firm orders for 53 CRJ's in
addition to the 43 previously delivered, and options for an additional 80
CRJ's.   The  Company also had firm orders for 41 328JETS in addition  to
the  21  previously delivered, and options for an additional 83  328JETs.
The  continued delivery of these additional jet aircraft into the  United
Express  and Delta Connection programs will expand the Company's business
into new markets and increase capacity in existing markets.

          During  the  first quarter of 2000, ACJet was engaged  in  pre-
operating  activities  related to the start up of  its  Delta  Connection
operations.   An  operating  certificate was  subsequently  approved  and
issued  by  the  Federal  Aviation  Administration  ("FAA"),  and   ACJet
commenced  revenue  service in the third quarter of  2000.   The  Company
plans  to combine the operations of ACJet into the operations of  ACA  in
2001.  Following the proposed combination, the Company would operate both
its  United  Express and its Delta Connection programs through  ACA.  The
combination is contingent on the Company receiving the required approvals
from the FAA and the Department of Transportation.

          Under  the Company's United Express agreement, United pays  the
Company  an  agreed amount per departure, and under the  Company's  Delta
Connection agreement, Delta pays the Company an agreed amount  per  block
hour   flown,  both  regardless  of  passenger  revenue,  and  both  with
additional  incentive  payments based on operational  performance.   Both
agreements  provide that the rates will be adjusted from  time  to  time.
During  the first quarter 2001, the Company and United established  rates
to be in effect for the Company's United Express flights throughout 2001.
For  Delta Connection flights, the Company and Delta continue to evaluate
operating history for this new service being provided by the Company, and
rates  presently being utilized for 2001 are consistent with those  rates
that were agreed to and used in 2000 and may be subject to adjustment.

          During 2000, United Airlines and US Airways announced plans for
a  merger,  with  United Airlines being the successor company.   The  two
companies  have recently stated that they continue to await  governmental
approvals  for  the merger to proceed and anticipate the  closing  to  be
delayed beyond the end of the second quarter of 2001.  On March 2,  2001,
the  Company  announced  it  entered  into  an  agreement  with  UAL   to
acquire-through  subsidiaries-the  three  regional  airlines   that   are
currently  wholly-owned by US Airways.  The three carriers are  Allegheny
Airlines, Piedmont Airlines and PSA Airlines.  Closing of the acquisition
from  US  Airways, which is contingent upon and would occur at  the  same
time  as closing of the proposed United/US Airways merger, is subject  to
regulatory  approvals and to termination rights by  UAL.   The  aggregate
purchase  price  for the three carriers, initially set at  $200  million,
will  be  paid  at closing in the form of a promissory  note  due  in  18
months.  Under  the terms of the agreement, the Company  will  not  remit
principal  or interest payments or accrue interest on the note until  and
if an agreement is finalized. The ultimate purchase price for each of the
three  regional carriers will be negotiated during the 18-month  term  of
the  promissory  note.   If agreement cannot be reached  on  an  ultimate
purchase  price  as  to any or all of the three carriers,  the  Company's
acquisition of that carrier will be unwound.  The ultimate purchase price
paid  by  the  Company  may vary substantially from  the  amount  of  the
promissory  note,  and there can be no assurances that the  Company  will
retain  any  or  all  of the three carriers.  If closing  occurs  on  the
initial  purchase  of  the three carriers but  the  Company  is  not  the
ultimate  purchaser  of at least one of the carriers,  the  Company  will
receive a fee of up to $10.5 million.  The results of operations, and any
capital requirements of the three regional carriers, are not expected  to
contribute to the Company's results of operations or impact its financial
position  until and if an ultimate purchase price is agreed  to  and  the
acquisition can no longer be unwound.

            The  Company  has  not  experienced  difficulties  with  fuel
availability  and expects to be able to obtain fuel at prevailing  prices
in  quantities  sufficient  to meet its future  requirements.  Delta  Air
Lines,  Inc. bears the economic risk of fuel price fluctuations  for  the
fuel  requirements of the Company's Delta Connection program, and  United
Airlines  bears such risk for the Company's United Express program.    As
such,  the Company expects that its results of operations will no  longer
be directly affected by fuel price volatility.


Liquidity and Capital Resources

          As  of  March  31, 2001, the Company had cash, cash equivalents
and short-term investments of $101.2 million and working capital of $90.7
million  compared to $121.2 million and $729 million respectively  as  of
December 31, 2000.  During the first three months of 2001, cash and  cash
equivalents  decreased  by $14.2 million, reflecting  net  cash  used  in
operating  activities  of  $11.4 million,  net  cash  used  in  investing
activities of $3.5 million, and net cash provided by financing activities
of  $.7  million.  The net cash used in operating activities is primarily
the  result  of  net  income  for the period of  $9.6  million,  non-cash
depreciation and amortization expenses of $3.4 million, and a $13 million
decrease  in  accounts receivable, offset by a $26.5 million increase  in
prepaid expenses related to aircraft rent and a $20.9 million decrease in
accrued liabilities related to the payment of lease termination fees  for
the  retirement of J-32 aircraft.  In order to minimize the costs related
to   aircraft  leveraged  lease  transactions,  the  Company  has  uneven
semiannual lease payment dates of January 1 and July 1. Approximately 44%
of  the  Company's annual aircraft lease payments are due in January  and
29% in July.  The decrease in accounts receivable is primarily the result
of  the  new  UA  agreement under which the Company receives  payment  in
advance  instead of in arrears.  The decrease in accrued  liabilities  is
primarily  the  result  of paying the lessor the  lease  termination  fee
relating  to  the  J-32  turboprop early  retirement.   (See  "Aircraft",
below.)  The net cash used in investing activities consisted primarily of
purchases  of  property  and equipment.  Financing  activities  consisted
primarily  of  payments on long-term debt and capital  lease  obligations
offset by the exercise of stock options.

     Other Financing

          In  February  1999,  the Company  entered into  an  asset-based
lending  agreement  with  two financial institutions  that  provided  the
Company  with  a  line of credit for up to $35 million depending  on  the
amount  of  assigned ticket receivables and the value of certain  rotable
spare  parts.   With the change in the United Express  agreement  from  a
prorate arrangement to a fee-per-departure/payment-in-advance arrangement
effective December 1, 2000, the Company's ticket receivable available for
assignment  has  been reduced to zero.  As such, the available  borrowing
under  the  line  of credit was limited to the value of  certain  rotable
spare  parts,  to a maximum of $8.0 million.  On May 2, 2001  the  asset-
based lending agreement was amended to add an additional $8.4 million  to
the  borrowing base, collateralized by the value of certain fixed assets.
The line of credit will expire on September 30, 2001, or upon termination
of  the United Express agreement, whichever is sooner.  The interest rate
on this line is LIBOR plus .75% to 1.75% depending on the Company's fixed
charges coverage ratio.  There were no borrowings on the line during 2000
or  to  date  in 2001.  As of May 2, 2001, the Company has pledged  $15.6
million of this line of credit as collateral for letters of credit issued
on  behalf  of the Company by a financial institution.  This  effectively
commits  most  of the line of credit.  The Company anticipates  replacing
this  existing  line of credit on or before September 30, 2001  when  the
current line expires.

     Other Commitments

          The  Company's Board of Directors has approved the purchase  of
up  to  $40  million of the Company's outstanding common  stock  in  open
market  or  private  transactions.  As of May 1,  2001  the  Company  has
purchased  2,128,000 shares of its common stock at an  average  price  of
$8.64  per  share.   None of these shares were purchased  in  2001.   The
Company  has  approximately $21.6 million remaining of  the  $40  million
authorization.

     Aircraft

          As  of May 1, 2001, the Company had a total of 53 CRJs on order
from  Bombardier,  Inc.,  and held options for 80  additional  CRJs.  The
Company  also  had  on  order  with Fairchild  Aerospace  Corporation  41
328JETs,  and held options on an additional 83 328JETs.  Of the  94  firm
aircraft deliveries, 22 are scheduled for the remainder of 2001,  30  are
scheduled  for  2002,  and 42 are scheduled for  2003.   The  Company  is
obligated  to  purchase  and  finance  (including  the  possible  use  of
leveraged leases) the 94 firm ordered aircraft at an approximate  capital
cost  of $1.6 billion.   The Company anticipates leasing all of its  year
2001  aircraft  deliveries on terms similar to previously  delivered  CRJ
aircraft.

           During 2000, the  Company  began  retiring  early  the  leased
19-seat  J-32 aircraft from the fleet.  As of May 1, 2001, 14  J-32s  had
been  removed from service.  The remaining 14 J-32s will be removed  from
service  during the remainder of 2001.  The early retirement  of  the  28
leased  J-32  aircraft resulted in the Company recording a $29.0  million
(pre-tax)  restructuring charge during 2000.    During  March  2001,  the
Company reached agreement with the lessor for the early return and  lease
termination of all of the J-32's and as a result paid a lease termination
fee which consisted of $19.1 million in cash, and the application of $5.2
million  in  credits due from the lessor. The Company believes  that  the
remainder  of the accrual will be adequate to provide for costs necessary
to  meet  aircraft  return conditions and does not expect  to  incur  any
additional charges against earnings for the early retirement of the  J-32
fleet.   The  early termination of these leases and the return  of  these
aircraft prior to lease expiration will enable the Company to satisfy its
lease  obligations and does not require the Company to assume  the  risks
and efforts required to maintain and remarket the aircraft.

     Capital Equipment and Debt Service

          Capital  expenditures for the first three months of  2001  were
$13.9  million  compared to $2.7 million for the  same  period  in  2000.
Capital expenditures for 2001 consisted primarily of the purchase of $9.6
million  in rotable spare parts for the regional jet aircraft,  and  $1.4
million  for  improvements to aircraft, which included $872,000  for  the
addition  of  smoke  detectors  to  the  J-41  aircraft.   Other  capital
expenditures included facility leasehold improvements, ground  equipment,
and  computer  and  office equipment.  For the  remainder  of  2001,  the
Company anticipates spending approximately $13 million for rotable  spare
parts  related  to  the  regional jet and J-41 aircraft,  ground  service
equipment, facilities, computers and software.

          Debt  service  including capital leases for  the  three  months
ended  March 31, 2001 was $725,000 compared to $1.0 million in  the  same
period of 2000.

          The   Company  believes  that,  in  the  absence   of   unusual
circumstances,  its  cash on hand, cash flow from operations,  and  other
available  equipment financing, will be sufficient to  meet  its  working
capital  needs,  capital expenditures, and debt service requirements  for
the next twelve months.

     Recent Accounting Pronouncements

          In  June  1998, the FASB issued Statement No. 133,  "Accounting
for  Derivative  Instruments  and  Hedging  Activities."  This  Statement
establishes accounting and reporting standards for derivative instruments
and  all  hedging activities.  It requires that an entity  recognize  all
derivatives  as  either  assets  or liabilities  at  their  fair  values.
Accounting for changes in the fair value of a derivative depends  on  its
designation and effectiveness.  For derivatives that qualify as effective
hedges,  the  change in fair value will have no impact on earnings  until
the   hedged  item  affects  earnings.   For  derivatives  that  are  not
designated as hedging instruments, and for the ineffective portion  of  a
hedging  instrument, the change in fair value will affect current  period
earnings.

          The  Company  adopted  Statement No. 133 effective  January  1,
2001.   The  impact  of adopting this statement has not  had  a  material
impact  on the Company's financial position or results of operations  for
the first quarter of 2001.

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

          The  Company's  principal market risk arises  from  changes  in
interest  rates.  The Company's exposure to market risk  associated  with
changes  in interest rates relates to the Company's commitment to acquire
regional  jets.  From time to time the Company has entered into  put  and
call  contracts designed to limit the Company's exposure to interest rate
changes  until  permanent  financing is  secured  upon  delivery  of  the
Bombardier  regional jet aircraft. At December 31, 2000 the  Company  had
one  interest rate hedge transaction open with a notional value  of  $8.5
million.  The Company settled this contract on January 3, 2001 by  paying
the counterparty $722,000.  As of March 31, 2001, the Company had no open
hedge transactions.
