PART II -- RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25(b), the following should
be completed. (Check box if appropriate).

      (a)   The reasons described in reasonable detail in Part III of this form
            could not be eliminated without unreasonable effort or expense;

[X]   (b)   The subject annual report, semi-annual report, transition report on
            Form 10-K, Form 20-F, 11-K or Form N-SAR, or portion thereof, will
            be filed on or before the fifteenth calendar day following the
            prescribed due date; or the subject quarterly report of transition
            report on Form 10-Q, or portion thereof, will be filed on or before
            the fifth calendar day following the prescribed due date; and

      (c)   The accountant's statement or other exhibit required by Rule
            12b-25(c) has been attached if applicable.



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

      The one-day delay in filing of Mesa Air Group, Inc.'s Form 11-K for the
      fiscal year ended September 30, 2003, is primarily attributable to its
      inability to timely gather the required information. The Form 11-K was
      filed on March 30, 2004.


(1)   Name and telephone number of person to contact in regard to this

      Securities Exchange Act of 1934 or Section 30 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 reports) been filed? If
      answer is no, identify report(s).

                                                                  [X] Yes [ ] No


(3)   It is anticipated that any significant change in results of operations
      from the corresponding period for the last fiscal year will be reflected
      by the earnings statements to be included in the subject report or portion

                                                                  [ ] Yes [X] No

      If so, attach an explanation of the anticipated change, both narratively
      and quantitatively, and, if appropriate, state the reasons why a
