INDEPENDENT AUDITORS' REPORT


Trustee and Plan Participants
Mesa Air Group, Inc. 401(k) Plan
Phoenix, Arizona

We have audited the accompanying statements of net assets available for benefits
of the Mesa Air Group, Inc. 401(k) Plan as of September 30, 2001 and 2000 and
the related statements of changes in net assets available for benefits for the
years then ended. These financial statements are the responsibility of the
Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the financial status of the Plan as of September 30, 2001 and 2000 and
the changes in its financial status for the years then ended in conformity with
accounting principles generally accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule listed in the
Table of Contents is presented for the purpose of additional analysis and is not
a required part of the basic financial statements, but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The schedule is the responsibility of the Plan's management. Such schedule
has been subjected to the auditing procedures applied in our audit of the basic
2001 financial statements and, in our opinion, is fairly stated in all material
respects when considered in relation to the basic financial statements taken as
a whole.

MESA AIR GROUP, INC. 401(k) PLAN

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED SEPTEMBER 30, 2001 AND 2000


1. DESCRIPTION OF THE PLAN

     The following description of the Mesa Air Group, Inc. 401(k) Plan (the
     "Plan") provides only general information. Participants should refer to the
     Plan agreement for a more complete description of the Plan's provisions.

     a.   General - The Plan is a defined contribution plan sponsored by Mesa
          Air Group, Inc. (the "Employer"). Under the provisions of the Plan, as
          amended, union and nonunion employees of the Employer and its
          affiliates, other than CCAir, Inc., who are 21 years of age and have
          completed one year of service, are eligible to participate. The Plan
          is subject to the provisions of the Employee Retirement Income
          Security Act of 1974 ("ERISA"). Employees may elect to allocate their
          contributions and their share of Employer contributions to various
          investment options as specified in the Plan.

     b.   Contributions and Vesting - Various accounts have been established for
          pre-tax voluntary employee contributions, forfeitures and earnings or
          losses from Plan assets. Accounts in use and their major provisions
          are as follows:

          -         Employee Contribution Account - Salary Reduction
                    Contribution Accounts have been established for pre-tax
                    voluntary employee contributions ranging from 1 percent to
                    15 percent of employee compensation up to the annual
                    deferral limit set by the Internal Revenue Code ("IRC"). All
                    such balances are fully vested.

          -         Employer Contributions Account - Contributions to this
                    account are at the discretion of the Employer. Employer
                    contributions match 50 percent of participant contributions
                    up to 10 percent of compensation. In addition, the Employer
                    may contribute to the Plan a discretionary amount as
                    determined by the Employer's Board of Directors as a profit
                    sharing contribution. Employer discretionary contributions
                    are allocated to active participants based upon the ratio
                    that each participant's annual compensation bears to the
                    total of all active participants' annual compensation.
                    Forfeitures are reallocated and may be used to reduce
                    Employer matching contributions.

          -         Employees are 20 percent vested in Employer contribution
                    accounts after three years of service. Vesting subsequently
                    increases 20 percent per year until the participant becomes
                    fully vested. Participants also become fully vested upon
                    becoming disabled, reaching age 65, or death, if still
                    employed by the Employer.

     c.   Participant Accounts - Each participant's account is credited with the
          participant's contribution, the Employer's matching contribution, and
          an allocation of the Employer's discretionary contribution and the
          Plan's earnings. The Employer's discretionary contribution is
          allocated to each participant in the ratio that each such
          participant's basic contribution (up to 4 percent) for the Plan year
          bears to all basic contributions of all participants. The Plan's
          earnings are allocated to


                                      -4-

          each participant in the ratio that each such participant's account
          balance for each fund bears to the total balance in that fund of all
          eligible participants on the date of each such allocation.

     d.   Investment Options - As of September 30, 2001, participants may direct
          employee contributions in 1 percent increments in any of six
          investment options offered by Putnam and a fund that invests in Mesa
          Air Group, Inc. common stock.

     e.   Payment of benefits is available upon retirement, death, disability or
          termination. Benefits are paid in the form of a lump-sum payment,
          installments or a nontransferable annuity. Participants may withdraw
          amounts from their account as set forth in the provisions of the Plan
          document for certain hardship situations.

     f.   Participant Loans - Participants may borrow from their accounts a
          minimum of $1,000 and a maximum equal to the lesser of $50,000,
          reduced by the highest outstanding loan balance during the preceding
          12 months, or 50 percent of their vested benefits. Loan terms range
          from one through five years unless funds are used to purchase a
          primary residence. The loans are secured by the balance in the
          participant's account. The loans accrue interest at a fixed rate
          determined by the Plan Administrator. The rate will be comparable to
          those currently available from commercial institutions. Interest rates
          range from 7 percent to 9.25 percent. Principal and interest are
          payable through monthly payroll deductions.

     g.   Plan Termination - Although it has not expressed any intent to do so,
          the Employer has the right under the Plan to discontinue its
          contributions at any time and to terminate the Plan subject to prior
          approval of the Internal Revenue Service and the Department of Labor.
          Upon complete discontinuance of contributions under the Plan, all
          employees' rights are nonforfeitable.

     h.   Tax Status - The Internal Revenue Service has determined and informed
          the Employer by letter dated December 23, 1998 that the Plan and
          related trust are designed in accordance with applicable sections of
          the IRC. The Plan has been amended since receiving the determination
          letter; however, the Plan Administrator believes the Plan is designed
          and is currently being operated in compliance with the applicable
          requirements of the IRC.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The Plan prepares its financial statements in accordance with accounting
     principles generally accepted in the United States of America. Significant
     accounting policies are as follows:

     a.   Basis of Accounting - The accompanying financial statements of the
          Plan have been prepared in accordance with accounting principles
          generally accepted in the United States of America using the accrual
          basis of accounting.

     b.   Use of Estimates - The preparation of financial statements in
          conformity with accounting principles generally accepted in the United
          States of America requires the Plan Administrator to make estimates
          and assumptions that affect the reported amounts of net assets
          available for benefits and changes therein, and disclosure of
          contingent assets and liabilities. Actual results could differ from
          those estimates.


                                      -5-

     c.   Investment Valuation - Mutual fund investments and Mesa Air
          Group, Inc. common stock are stated at market value based upon quoted
          market prices as determined by the Plan Trustee. Participant loans are
          valued at cost, which approximates fair value. Purchases and sales are
          recorded on a trade-date basis. Dividends are recorded on the
          ex-dividend date.

     d.   Administrative Expenses - All administrative expenses are paid by the
          Employer.

     e.   Payment of Benefits - Benefits are recorded when paid.

     The following presents investments that represent five percent or more of
