Part III--Narrative

State below in reasonable  detail the reasons why Forms 10-K,  20-F, 11-K, 10-Q,
N-SAR,  and N-CSR,  or the transition  report or portion  thereof,  could not be
filed within the prescribed period.

(Attach Extra Sheets if Needed)

The  Registrant's  quarterly report on Form 10-Q for the quarter ended September
30,  2004  could  not be filed at this  time  without  unreasonable  effort  and
expense. As previously  disclosed in the Registrant's Current Report on Form 8-K
filed on October 28, 2004, the Registrant  and seven of its  subsidiaries  filed
voluntary  petitions for relief under Chapter 11 of the United States Bankruptcy
Code in the United States Bankruptcy Court for the Southern District of Indiana.
The  Registrant  is in  the  process  of  negotiating  the  terms  of a  crucial
debtor-in-possession  financing  arrangement and a definitive  agreement for the
sale of certain  assets and assumption of  liabilities  which require  intensive
consultation with creditors and other affected parties.  The Registrant  expects
to file its Form 10-Q in a timely manner,  as permitted by Rule 12b-25 under the
Exchange Act.

                    of the  Investment  Company Act of 1940 during the preceding
                    12 months or for such shorter period that the registrant was
                    required to file such report(s) been filed? If the answer is
                    no, identify report(s).

                    operations from the corresponding period for the last fiscal
                    year will be  reflected  by the  earnings  statements  to be

                    narratively and  quantitatively,  and if appropriate,  state
                    the reasons why a reasonable  estimate of the results cannot
                    be made.

                            ATTACHMENT TO PART IV OF
                                 FORM 12B-25 OF
                                ATA HOLDINGS CORP
                      WITH RESPECT TO ITS FORM 10-Q FOR THE
                        QUARTER ENDED SEPTEMBER 30, 2004

For the quarter and nine months ended  September 30, 2004,  ATA Holding Corp and
its  Subsidiaries  (the  "Company")  had an operating  loss of $16.2 million and
$49.1 million,  respectively,  as compared to operating  income of $29.5 million
and $86.9  million in the same  periods of 2003.  The  Company had a net loss of
$30.9  million and $120.9  million in the third quarter and first nine months of
2004,  respectively,  as  compared  to a net  income of $7.7  million  and $40.0
million in the same periods of 2003.  Net income (loss) per diluted common share
was ($2.65) and ($10.32) for the third  quarter and nine months ended  September
30, 2004,  respectively,  as compared to $0.53 and $2.65 for the same periods in
2003.  The net loss for the nine months  ended  September  30,  2004  includes a
non-operating  charge of $27.3 million  related to a loss on  extinguishment  of
debt from the exchange offers  completed on January 30, 2004. The net income for
the first nine  months of 2003  includes  the  receipt of $37.2  million in U.S.
Government funds.

Operating  revenues  increased  3.5% to $401.2  million in the third  quarter of
2004,  as compared to $387.7  million in the same period of 2003,  and increased
2.6% to $1.179  billion in the first nine months of 2004,  as compared to $1.149
billion in the same period of 2003. Consolidated revenue per available seat mile
("RASM")  decreased  0.5% to 7.42  cents  and 0.1% to 7.24  cents  in the  third
quarter and first nine months of 2004,  respectively,  as compared to 7.46 cents
and 7.25 cents in the third  quarter and first nine months of 2003. In the first
nine months of 2004,  the Company's  scheduled  service  revenues were adversely
affected  by the  industry's  added  capacity,  which  especially  impacted  the
Company's  transcontinental  and other  east-west  markets in early  2004.  As a
result,  the Company  cancelled some of its east-west  routes beginning in March
and April 2004 while  continuing to review its other scheduled  service markets.
In  addition,  in the first  nine  months of 2004 the  Company  continued  to be
challenged by competitive pricing which included  extraordinary fare discounting
by several airlines. The Company's third quarter 2004 scheduled service revenues
were also adversely  impacted by the hurricanes in Florida.  Military/government
revenue  increased  in the three and nine month ended  September  30,  2004,  as
compared  to the  same  periods  of  2003,  mainly  due to an  increase  in fuel
escalation revenue as a result of the increasing cost of fuel.

Operating  expenses  increased  16.5% to $417.4  million in the third quarter of
2004,  as  compared  to $358.2  million in the  comparable  period of 2003,  and
increased  15.5% to $1.228 billion in the first nine months of 2004, as compared
to $1.063  billion in the same period of 2003.  Consolidated  cost per available
seat mile ("CASM")  increased  11.9% to 7.72 cents in the third quarter of 2004,
as compared to 6.90 cents in the third quarter of 2003,  and increased  12.5% to
7.54 cents in the first nine  months of 2004,  as  compared to 6.70 cents in the
same  period  of  2003.  Operating  expenses  were  primarily  impacted  by  the
increasing  cost of fuel,  which  resulted in a CASM  increase of 0.53 cents and
0.32  cents in the  third  quarter  and  first  nine  months,  respectively.  In
addition,  operating  expenses for the first nine months of 2003  benefited from
the receipt of $37.2 million in U.S.  Government funds for the  reimbursement of
expenses  incurred and revenue  foregone related to enhanced  aviation  security
after  September  11,  2001,  which was  recorded  as a reduction  to  operating
expenses.

The  Company's  unrestricted  cash balance was $57.6 million as of September 30,
2004, as compared to $150.0 million as of June 30, 2004.
