              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.    Basis of Presentation: The accompanying unaudited condensed consolidated
      financial statements have been prepared in accordance with generally
      accepted accounting principles for interim financial information and with
      the instructions to Form 10-Q and Article 10 of Regulation S-X.
      Accordingly, they do not include all of the information and footnotes
      required by generally accepted accounting principles for complete
      financial statements. In the opinion of management, all adjustments
      (consisting of normal recurring accruals) considered necessary for a fair
      presentation have been included. Operating results for the three-month
      and six-month periods ended March 31, 1999 are not necessarily indicative
      of the results that may be expected for the fiscal year ending September
      30, 1999.

      These condensed consolidated financial statements should be read in
      conjunction with the Company's consolidated financial statements and
      footnotes included in the annual report for the fiscal year ended
      September 30, 1998.

2.    The condensed consolidated financial statements include the accounts of
      Mesa Air Group, Inc. and its wholly owned subsidiaries Mesa Airlines,
      Inc., WestAir Holding, Inc., Air Midwest, Inc., Mesa Leasing, Inc., MAGI
      Insurance, Ltd., Regional Aircraft Services, Inc. and MPD, Inc. During the
      quarter ended March 31, 1999, Mesa Air Group, Inc. sold substantially all
      of the assets of Four Corners Aviation Inc., a wholly-owned subsidiary of
      Mesa Air Group, for its approximate book value of $4.5 million. All
      significant intercompany balances and transactions have been eliminated in
      consolidation. See discussion of WestAir Holding, Inc. in the "Legal
      Proceedings" section of this report.

3.    Income tax benefit in the six-month period ended March 31, 1998 has been
      recognized only to the extent of previously recorded deferred tax
      liability. For the quarter ended March 31, 1999 and the six-month period
      then ended, the Company did not recognize any income tax expense as a
      result of net operating loss carryforwards.

This Form 10-Q contains certain statements including, but not limited to,
information regarding the replacement, deployment, and acquisition of certain
numbers and types of aircraft, and projected expenses associated therewith;
costs of compliance with FAA regulations and other rules and acts of Congress;
the passing of taxes, fuel costs, inflation, and various expenses to the
consumer; the relocation of certain operations of Mesa; the resolution of
litigation in a favorable manner; compliance with Year 2000 issues, and certain
projected financial obligations. These statements, in addition to statements
made in conjunction with the words "expect," "anticipate," "intend," "plan,"
"believe," "seek," "estimate," and similar expressions, are forward-looking
statements which we believe are within the meaning of the safe harbor provision
of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended. These statements relate to future
events or the future financial performance of Mesa and only reflect Management's
expectations and estimates. The following is a list of factors, among others,
that could cause actual results to differ materially from such forward-looking
statements: changing business conditions in certain market segments and
industries; an increase in competition along the routes Mesa operates or plans
to operate; material delays in completion by the manufacturer of the ordered and
yet-to-be delivered aircraft; changes in general economic conditions; changes in
fuel price; changes in regional economic conditions; Mesa's relationship with
employees and the terms of future collective bargaining agreements; and the
impact of current and future laws, Congressional investigations, and
governmental regulations affecting the airline industry and Mesa's operations;
bureaucratic delays; amendments to existing legislation; consumers unwilling to
incur greater costs for flights; unfavorable resolution of negotiations with
municipalities for the leasing of facilities; and risks associated with
litigation outcomes. One or more of these or other factors may cause Mesa's
actual results to differ materially from any forward-looking statement. Mesa is
not undertaking any obligation to update any forward-looking statements
contained in this Form 10-Q.


Item 2.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

GENERAL

Mesa Air Group, Inc. and its subsidiaries (collectively referred to as "Mesa" or
the "Company") is an independently owned regional airline serving 114 cities in
28 states, the District of Columbia, Toronto, Canada and Guaymas and Hermasillo,
Mexico. At March 31, 1999, Mesa operated a fleet of 112 aircraft with
approximately 1,000 daily departures.

Mesa's airline operations are conducted by two regional airlines utilizing
hub-and-spoke systems. Mesa Airlines, Inc. ("MAI"), a wholly-owned subsidiary of
Mesa, operates as America West Express under a code-sharing agreement with
America West Airlines, Inc. ("America West") and as US Airways Express under
code-sharing agreements with US Airways, Inc. ("US Airways") and also operates
an independent division, Mesa Airlines, from a hub in Albuquerque, New Mexico.
Air Midwest, Inc. , a wholly owned subsidiary of Mesa, also operates under a
code-sharing agreement with US Airways and flies as US Airways Express.

During the past twelve months, significant changes have occurred at Mesa. In May
1998, Mesa and its WestAir subsidiary ceased all operations as United Express,
which resulted in a loss of approximately 45% of Mesa's consolidated revenue and
89 excess aircraft. Mesa successfully redeployed and disposed of almost all of
the excess aircraft. In addition, Mesa acquired an additional 9 Canadair
Regional Jets since March 1998. All of the 24 regional jets which Mesa currently
operates fly under fee per departure contracts with US Airways and America West.

Mesa and CCAIR, Inc., a regional airline based in Charlotte, North Carolina,
executed a definitive purchase agreement dated as of January 28, 1999, whereby
CCAIR will become a wholly-owned subsidiary of Mesa. The transaction is valued
at approximately $54 million and is intended to be accounted for as a pooling of
interests. The purchase agreement contemplates an all stock transaction whereby
Mesa will acquire all outstanding shares of CCAIR common stock by issuing Mesa
shares equivalent in value to $4.35 for each share of CCAIR common stock,
subject to a maximum of .6214 shares (at a Mesa share price of $7.00) and a
minimum of .435 shares (at a Mesa share price of $10.00). Consummation of the
transaction is subject to certain conditions, including regulatory approval,
satisfaction of closing conditions and shareholder approval from both the CCAIR
shareholders (as to the merger) and the Mesa shareholders (as to the issuance of
Mesa shares in the merger). The shareholders of both CCAIR and Mesa will vote on
the transaction at each company's Special Meeting of Shareholders to be held on
June 8, 1999.

Mesa's long-term business strategy is to operate a competitive and profitable,
high-frequency, quality service airline, primarily with a hub-and-spoke system.
The strategy is implemented through a disciplined approach to the regional
airline business which incorporates (i) regional diversification, (ii) focus on
profitable markets, (iii) reactions to the changing economic and competitive
environment, and (iv) a modern, efficient aircraft fleet that positions the
airline to be able to capitalize on future growth opportunities.

As a result of the Airline Deregulation Act of 1978, as amended, airlines in the
United States have been free to set their own domestic fares without
governmental regulation. Mesa has increasingly relied on fee per departure
contractual agreements with its two code-sharing partners to generate revenue.
All of Mesa's America West Express operations (except Guaymas and Hermasillo,
Mexico) and all its US Airways Express jet operations are on a fee per departure
basis. For the quarter ended March 31, 1999, 46.9% of Mesa's airline revenues
were derived from fee per departure contractual arrangements. The percentage of
revenue generated under the fee per departure agreements is expected to
significantly increase in 1999 as Mesa adds additional regional jets to its
America West Express and US Airways Express operations. Mesa derives the 


                                       7
   8
remainder of its passenger revenues from a combination of local fares, through
fares, and joint fares. Local fares are fares for one-way and round-trip travel
provided by Mesa within its route system. Passengers connecting with other
carriers also frequently use local fares. A through-fare is a fare offered to
passengers by either America West or US Airways which generally provides cost
savings to the passenger who transfers to the major carrier's code-sharing
partner on routes flown by the code-sharing partner. Through-fares are prorated
in accordance with standards specified in the various code-sharing agreements.
Joint fares are single fares for travel combining flights with Mesa and other
airlines, which are not code-sharing partners with Mesa. With joint fares, the
passenger generally pays a single lower fare than the sum of the local fares
charged for the combined flights. Mesa has been able to negotiate joint-fare
arrangements with some major carriers as an additional means of deriving
passengers connecting through its hub cities.

On May 3, 1999 Mesa Airlines, Inc. reached a tentative agreement with the
Association of Flight Attendants, (AFA) the collective bargaining representative
of Mesa's flight attendants. Mesa anticipates ratification by the flight
attendants of their first collective bargaining agreement in the quarter ending
June 30, 1999.

The following tables set forth year-to-year comparisons for the periods
indicated below:

RESULTS OF OPERATIONS

Operating Revenues:

Operating revenues decreased by $41.7 million to $77.9 million in the quarter
ended March 31, 1999, from $119.6 million in the quarter ended March 31, 1998.
The revenue decrease was primarily due to a 46.5% decrease in passengers
carried. Available seat miles ("ASMs") decreased by 12.1%, and the load factor
decreased from 54.7% during the quarter ended March 31, 1998 to 48.9% for the
comparable current quarter. The decrease in ASM's and passengers carried is
primarily attributable to the discontinuation of the Company's United Airlines
Express ("United") operations. (See Part II - Item 1. Legal Events.)

Operating revenues decreased by $89.1 million to $155.1 million for the
six-month period ended March 31, 1999 from $244.2 million for the six-month
period ended March 31, 1998. This decrease is primarily due to the decrease in
the number of passengers carried in this period as compared to the six months
ended March 31, 1998, as explained above.

Operating Expenses:

As the Company's proportion of Regional Jets to total aircraft increases, the
operating cost per ASM decreases significantly. In addition, the fee per
departure contracts eliminate certain expenses such as commissions and
reservation fees.

Flight Operations:

Flight operations costs decreased by $15.1 million to $32.6 million for the
quarter ended March 31, 1999 from the quarter ended March 31, 1998 and decreased
by $29.7 million to $66 million for the six-month period ended March 31, 1999
from the six-month period ended March 31, 1998. The decrease in ASM's, as noted
under "Operating Revenues," was attributable to the removal of 89, Jetstream,
Beech 1900 and Brasilia aircraft as a result of the cessation of United Express
operations and the addition of 9 Canadair Regional Jet aircraft ("CRJ") over the
number in service at March 31, 1998. Flight operations expenses decreased both
quarter over quarter and for the six-month period ended March 31, 1999. The
decrease over the quarter ended March 31, 1999 included a $9.1 million decrease
in pilot costs, a $1.4 million decrease in training costs and a $4.0 million
decrease in aircraft leasing and ownership costs. In the six months ended March
31, 1999, the cost decreases were similar and were a result of the changes in
fleet composition. Fuel cost decreased $6.0 million for the quarter ended March
31, 1999 and $12.1 million for the six months then ended. A price reduction of
approximately 2 cents per gallon over the period(s) contributed approximately
$.6 million to the reduction.


Maintenance Expense:

Maintenance expense decreased by $9.4 million in the quarter ended March 31,
1999 to $14.2 million from $23.6 million in the same quarter of the previous
fiscal year and decreased by $19.0 million in the six-month period ended March
31, 1998. The decrease for the quarter and for the six months ended March 31,
1999 was primarily a result of the changes to the fleet as discussed under
"Flight Operations."

Aircraft and Traffic Service Expense:

Aircraft and traffic service expense decreased by $11.3 million to $10.4 million
during the quarter ended March 31, 1999 from $21.7 million in the comparable
quarter of the previous fiscal year. Aircraft and traffic service expense
decreased by $23.5 million to $20 million for the six-month period ended March
31, 1999 from $43.5 million for the six-month period ended March 31, 1998. The
decrease for the quarter ended March 31, 1999 included a $3.6 million reduction
in station wages, a $3.2 million reduction in rent and other station contract
services and a $1.3 million reduction in landing fees. These decreases were
primarily the result of a reduced fleet size and a reduction in flying
activities. The percentage reductions for the six months ended March 31, 1999
were similar to those for the quarter. 

Promotion and Sales:

Promotion and sales expense decreased $11.6 million to $5.1 million for the
quarter ended March 31, 1999 from the prior year's comparable quarter and
decreased by $24.8 million to $10.4 million for the six-month period ended March
31, 1999 over the six-month period ended March 31, 1998. The primary reason for
these decreases was a significant decline in the number of passengers carried as
a result of the shutdown of United Express operations.

                                       9
   10
General and Administrative Expense:

General and administrative expense decreased by $2.1 million for the three-month
period ended March 31, 1999 to $5.4 million as compared to the quarter ended
March 31, 1998 and decreased $5.4 million to $10.1 million for the six-month
period ended March 31, 1999, as compared to the six-month period ended March 31,
1998. The primary causes of the decrease for the quarter ended March 31, 1999
were a $.7 million decrease in property taxes, a $.9 million decrease in health
insurance claims and a $.6 million decrease in property, casualty and liability
insurance. The primary causes of the decrease for the six-month period ended
March 31, 1999 versus the comparable period in 1998 was a $1.6 million decrease
in the amount of health insurance claims paid, a $1.2 million decrease in
property taxes and a $1.4 million decrease in property, casualty and liability
insurance.

Depreciation and Amortization:

Depreciation and amortization decreased by $2.9 million to $4.4 million for the
quarter ended March 31, 1999 as compared to the quarter ended March 31, 1998 and
by $5.6 million to $8.9 million for the six-month period ended March 31, 1999
from the comparable six-month period in the prior year. The decrease is
attributable to aircraft fleet reductions.

Other Operating Items:

During the quarter ended March 31, 1998 the Company recognized a $4.0 million
loss provision related to the discontinuation of its independent jet operation
in Fort Worth, Texas. The Company also recognized $2.5 related to anticipated
settlement costs of a shareholder class action lawsuit. During the six-month
period ended March 31, 1998, the Company also recognized a $33.9 million loss
provision related to the discontinuation of service under the Code-Sharing
Agreements with United Airlines.

Other Non-Operating Expense:

Other non-operating expense increased by $1.1 million to $2.9 million in the
quarter ended March 31, 1999 from $1.8 million in the quarter ended March 31,
1998, as a result of a gain on the sale of Mesa's investment in America West
Airlines, which amounted to $11.1 million in cash and a recognized gain of $4.5
million. Interest expense decreased by $2.8 million to $4.0 million in the
quarter ended March 31, 1999 from $6.8 million in the quarter ended March 31,
1998, due to lower outstanding principal loan balances as a result of the
retirement of aircraft. Interest expense for the six-month period ended March
31, 1999 was reduced by $4.7 million over the comparable six-month period in
1998, as a result of lower outstanding principal loan balances due to
aircraft fleet reductions.

LIQUIDITY AND CAPITAL RESOURCES

Mesa's cash, cash equivalents and marketable securities as of March 31, 1999
were $65.5 million. Mesa's net cash flows from operations were approximately
$19.0 million during the six months ended March 31, 1999. Mesa makes semiannual
lease payments on a substantial portion of its leased aircraft with
approximately $15 million due in January and $7.0 million July. Mesa's cash, 
cash equivalents and marketable securities are intended to be used for working
capital, capital expenditures and acquisitions.

Mesa had receivables of approximately $20.8 million at March 31, 1999, which
consist primarily of amounts due from code-sharing partner US Airways and
passenger ticket receivables due through the Airline Clearing House. Under the
terms of the US Airways agreement, Mesa receives a substantial portion of its
revenues through the Airline Clearing House. Historically, Mesa has generated
adequate cash flow to meet its operating needs. Termination of the United
Express code-sharing agreement has left Mesa with excess aircraft which will
need to be re-deployed on other routes, or alternatively, sold or returned to
their lessors. At March 31, 1999, Mesa had 16 excess Beech 1900D. On February
25, 1999 Mesa announced that it had sold 16 of the excess Beech 1900D aircraft
anticipated to be delivered to the Purchaser by September 1999. 

Mesa has significant lease obligations and debt payments on existing aircraft.
At March 31, 1999, Mesa had 83 aircraft with debt balances with maturities
through December 2011. During 1996, Raytheon Aircraft Credit Corporation
("RACC") provided financing on 69 Beech 1900D aircraft. In April 1998, Mesa
reached an agreement with RACC, to defer the monthly principle and interest
payments due on the aircraft for the months of May, June and July. The payments
were deferred by extending the financing terms for an additional three months.
In addition, RACC agreed to finance two Beech 1900 aircraft owned by Mesa for an
amount equal to the monthly payments due on 69 Beech 1900D aircraft for the
months of August, September and October 1998. Mesa then 


                                       10
   11
used the proceeds of the financing for those monthly payments. The two aircraft
were financed by RACC with non-recourse, non-interest bearing loans and are in
the process of being sold. In the fall of 1998, RACC refinanced from another
lender an additional 14 Beech 1900D aircraft. The total financing provided by
RACC is secured by the aircraft and totals $261 million at March 31, 1999 with
monthly payments of $2.2 million.

In August 1998 Mesa reached an Agreement with RACC whereby RACC agreed to
purchase excess Beech 1900 aircraft parts from Mesa. As a result of disputes
between Mesa and RACC regarding the applicability and value of certain aircraft
parts under the Agreement, Mesa withheld its monthly payment on 83 Beech 1900
aircraft to RACC for the months of November and December 1998. In an Agreement
dated January 7, 1999, Mesa and RACC resolved the issues regarding these parts
and RACC accepted them in lieu of payment for the months of November and
December 1998. To the extent that any Event of Default, as defined in the
financing documents, may have occurred for the months of November and December
1998, they have been deemed fully cured pursuant to the terms of the Agreement
with RACC.

Mesa is the lessee of one (1) Embraer EMB 120 aircraft with Fleet Capital
Leasing ("Fleet") as lessor. This aircraft is no longer in service with the
Company, however, it is maintained in accordance with Mesa's FAA approved
maintenance program. On January 11, 1999, Fleet delivered to Mesa a notice of
default under the aircraft lease for failing to maintain the aircraft in
accordance with the requirements of the applicable aircraft lease. Mesa has
responded to Fleet, and to the extent that an Event of Default under the lease
may have occurred, the issue has been resolved and the aircraft has subsequently
been traded-in to Bombardier.

Future lease payments due under all aircraft operating leases were approximately
$592 million at March 31, 1999. These leases are classified as operating leases
and therefore are not reflected as liabilities in the accompanying consolidated
balance sheet. At March 31, 1999, 45 aircraft were leased by Mesa with terms
extending through June 2016. Total lease expense for the three months ended
March 31, 1999 was $8.5 million, and for the six months then ended was $16.1
million.

Mesa has ordered 32 CRJ aircraft for use in its America West Express operation
in Phoenix, Arizona and Columbus, Ohio, and for its US Airways Express
operations on the East Coast. As of May 1, 1999, Mesa had received 24 of the 32
CRJ aircraft on order and expects to take delivery of the remaining 8 by the end
of 1999. Mesa has Rolling Options for an additional 16 CRJ aircraft with a
delivery schedule subject to availability of one per month beginning June 2000.
The value of these additional 16 CRJ aircraft, at listed prices, is
approximately $320 million. Permanent financing has been completed on 11 of
the 24 aircraft for which Mesa has entered into operating leases. The
manufacturer, Bombardier Regional Aircraft Division, is providing interim
financing and has agreed to provide back up financing at agreed upon rates if
Mesa is not successful in obtaining permanent financing. The financing rate, but
not the commitment, is subject to there being no material adverse change in
Mesa's creditworthiness. Mesa anticipates finalizing operating leases upon the
completion of permanent financing for the additional 13 aircraft delivered
through April 1999 and for the remaining 8 aircraft to be delivered in 1999.
In December 1997, Mesa gave notice to Bombardier, the manufacturer, of its
intent to exercise its option to purchase the 16 Rolling Option aircraft.
Bombardier contends that the aircraft are subject to availability and that they
are no longer available. Mesa disputes Bombardier's position. The matter has not
yet been resolved.

Mesa has negotiated 10-year engine maintenance contracts with General Electric
Aircraft Engines ("GE") for the CRJ aircraft and with Pratt and Whitney, Canada
Aircraft Services ("PWC") for the Dash 8-200 aircraft. The GE engine maintenance
contract provides coverage for the engines on the first 16 CRJ aircraft to be
delivered. Mesa is presently negotiating with GE to add the CRJ aircraft engines
for 16 additional CRJ aircraft to this maintenance contract. The PWC contract
provides coverage for all Dash 8-200 aircraft engines operated by Mesa. Both
contracts provide for payment at the time of the repair event and a fixed dollar
amount per flight hour, subject to escalation based on changes in the Consumer
Price Index, for the number of flight hours incurred since the previous event.

In connection with the $110 million loss provision recorded of which $72.1
million was for the fiscal year ended September 30, 1997 and $37.9 million was
for the fiscal year ended September 30, 1998, Mesa incurred $5.8 million in cash
expenditures in the quarter ended March 31, 1999 and $9.2 million in cash
expenditures for the six months then ended, primarily for the disposition of
surplus aircraft. 


                                       11
   12
severance and other expenditures. Mesa estimates that the cash expenditures for
fiscal year 1999 attributable to the remaining costs related to the termination
of the United Express code-share agreements and the shut down of the Denver and
Fort Worth operations, primarily related to aircraft interest and severance
costs. At March 31, 1999, Mesa had applied $85.4 million to this provision,
leaving a balance of $24.6 million for remaining disposition costs. Mesa
estimates that the remaining provision will be adequate for the remaining
disposition expenses. Mesa's estimation that the remaining provision will be
adequate for the remaining disposition expenses is a forward-looking statement.

Management's belief that Mesa will have adequate cash flow to meet its operating
needs is a forward-looking statement. Actual cash flow could materially differ
from the forward-looking statement in the event of the termination of one or
more code-sharing agreements; failure to sell, dispose of, or re-deploy excess
aircraft in a timely manner; a substantial decrease in the number of routes
allocated to MAI under its code-sharing agreement with US Airways; reduced
levels of passenger revenue, additional taxes or costs of compliance with
governmental regulations, fuel cost increases, increase in competition, increase
in interest rates, general economic conditions and unfavorable settlement of
existing or potential litigation. Mesa has minimal market risk with respect to
market risk instruments such as foreign currency exchange risk and commodity
price risk. Mesa is subject to interest rate risk with respect to current and
future aircraft financings.

YEAR 2000 ISSUES

Many currently installed computer systems and software products are coded to
accept two digit entries in the date code field. These date code fields will
need to accept four digit entries to distinguish 21st century dates from 20th
century dates. Any programs that have date/time sensitive software may recognize
a date using "00" as the year 1900 rather than the year 2000. This could result
in the computer shutting down or performing incorrect computations.
Consequently, computer systems and software used by many companies will need to
be upgraded to comply with such "Year 2000" requirements. Certain of Mesa's
systems, including information and computer systems and automated equipment,
will be affected by the Year 2000 issue.

Mesa has completed a comprehensive inventory of its core business applications
to determine the adequacy of these systems to meet future business requirements.
The date, Mesa's Year 2000 assessment efforts have focused on those business
computer applications (i.e., the systems that Mesa is dependent upon for the
conduct of day-to-day business operations). Year 2000 readiness is only one of
many factors considered in this assessment. Out of this effort, a number of
systems have already been identified for upgrade or replacement. In no case has
a system been replaced or intended to be replaced solely because of Year 2000
issues, although in some cases the timing of system replacement is being
accelerated. Thus, Mesa does not believe the costs of these system replacements
are specifically Year 2000 related. Additionally, while Mesa may have incurred
an opportunity cost for addressing the Year 2000 issue, it does not believe that
any specific information technology projects have been deferred as a result of
its Year 2000 efforts.

Mesa's reservation systems are tied to its code-sharing partners, US Airways and
America West. In February, the computer reservations system (CRS) used by Mesa
and those CRS's used by each of its partners, completed a major milestone. These
systems handled the Year 2000 rollover date by successfully processing
reservations for air travel after December 31, 1999. Mesa representatives will
continue to be engaged in on-going dialogue regarding their Year 2000 progress.

Mesa has installed an upgraded version of its current accounting system, which
is represented by the vendor to be Year 2000 compliant but has not yet been
tested. A new flight operations software package, which the vendor has stated to
be Year 2000 compliant, is currently being installed and tested. The
applications within this system will support crew scheduling in addition to crew
and flight tracking.

Mesa has had extensive discussions with the manufacturers of its various
aircraft to discuss any potential Year 2000 issues. No embedded systems in the
equipment, which have the potential to be adversely affected by the Year 2000
rollover, have been identified. The aircraft manufacturers are also required to
report the Year 2000 status of their aircraft to the FAA. Mesa currently has
three employees devoted full-time to the Year 2000 Project: two in Information
Technologies and one in the Maintenance Department. Projects are currently
underway to evaluate the remaining systems (including tracking of maintenance
parts, revenue accounting and payroll) and replace them if needed, with testing
and implementation scheduled for the remainder of calendar year 1999. As with
systems that have already been replaced, Mesa does not believe that the costs of
these replacements are specifically Year 2000 related. Mesa has upgraded or
replaced many of its personal computers and related system components which were
not determined to be specifically related to the Year 2000 conversion, but were
part of a previously scheduled, larger system upgrade. Mesa has spent
approximately $1 million on these upgrades thus far, and anticipates another $.5
million in expenditures to complete its system upgrade. Mesa expects to incur
Year 2000 related costs to repair some of its systems; these anticipated costs
have been estimated at an additional $.5 million.

Mesa is currently assessing other potential Year 2000 issues, including
non-information technology systems. The Year 2000 readiness status of Mesa's
business partners, vendors, suppliers, contractors, financial institutions and
other third parties is currently being assessed. Mesa believes that a likely
worst-case scenario for the Year 2000 issue would be if Mesa or any third
parties with which it has business relationships, would not successfully
complete their Year 2000 remediation efforts. If this were to occur, the
potential for Mesa to encounter business disruption could have a material
adverse effect on its day-to-day business operations, and therefore, its
financial position. In addition, Mesa could be materially impacted by widespread
communications or other utility outages; economic or financial market
disruption; or by computer system failures or anomalies.

Mesa has begun establishing formal Year 2000 contingency plans. Mesa maintains
and deploys contingency plans designed to address various other potential
business interruptions. These plans will address business interruptions of key
vendors and suppliers which may be affected by the Year 2000 rollover.

Mesa feels it has made steady progress in heading off potential problems related
to the Year 2000 century rollover, and is on track to complete its project by
late this year.

PART II.   OTHER INFORMATION

Item 1.    Legal Proceedings

In June 1997, UAL filed a complaint in the United States District Court for the
Northern District of Illinois against two subsidiaries of Mesa, Mesa Airlines,
Inc. and WestAir Commuter Airlines, Inc., seeking a judicial declaration of the
parties' rights and obligations under two separate written agreements, pursuant
to which MAI and WestAir allegedly agreed to provide certain airline
transportation services to UAL including the provision of scheduled air
transportation services in certain areas of the United States under the service
mark "United Express." UAL contends that, under these agreements, UAL has the
right to "increase, decrease, or in any other way adjust the flight frequencies,
markets, or both" in certain airports currently serviced by WestAir and/or MAI.
In January 1998, UAL amended its complaint to include damages related to MAI's
purported breach of contract to provide specified levels of service in certain
cities. On November 1, 1998, UAL filed a motion with the Court to amend its
Complaint to include an additional $4.0 million in damages resulting from Mesa's
alleged failure to remit baggage 


                                       13
   14
fees at Denver International Airport to UAL. The motion has not yet been
considered. MAI and WestAir dispute the principal contentions in UAL's
complaint, and unless a satisfactory negotiated resolution is achieved, intend
to defend their positions vigorously. Furthermore, MAI and WestAir believe that
UAL has breached its code-sharing agreements with the respective entities and
have filed a counterclaim seeking to recover the substantial damages which have
been incurred by the business of MAI and WestAir.

In addition, Mesa and WestAir have filed suit against UAL and SkyWest Airlines,
Inc. ("SkyWest"). SkyWest was contracted to be Mesa's successor on the West
Coast. The complaint alleges that SkyWest unlawfully interfered with Mesa's and
WestAir's contracts with UAL. It further alleges improper conduct on the part of
UAL and SkyWest in terminating markets under the Mesa agreement and leading to 
the non-renewal of the WestAir agreement. Mesa is seeking substantial damages
against each defendant.

In February 1999, a complaint was filed against WestAir Commuter Airlines, Inc.
and Mesa Airlines, Inc. in Superior Court of California for Fresno County, by
the former WestAir pilots, seeking severance pay in the amount of $1.2 million
plus economic and punitive damages as a result of WestAir's termination of
airline operations, following United Airlines' non-renewal of the WestAir
agreement. Mesa does not believe that the pilots will prevail on their claims
and intends to defend this matter vigorously.

Mesa is also a party to legal proceedings and claims which arise in the ordinary
course of business.
