Item 2.

                              MESA AIR GROUP, INC.

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


GENERAL

Mesa Air Group, Inc. and its subsidiaries (collectively referred to herein as
"Mesa" or the "Company") is a regional airline operating as America West
Express, Mesa Airlines, US Airways Express and, through May 31, 1998, United
Express (see, "Other Events--United Airlines") serving 113 cities in 29 states,
Canada and the District of Columbia. At June 30, 1998, Mesa utilized a fleet of
107 aircraft with approximately 1,000 daily departures.

Mesa's long-term strategy is to profitably service routes not directly served by
major air carriers and to supplement service of major carrier code partners on
certain routes. The Company evaluates market demand and utilizes its fleet of
aircraft to meet that demand. Code-sharing agreements with certain of the major
air carriers provide benefits from the name recognition, reservation systems,
marketing and promotional efforts of those carriers. Mesa operates a fleet of
new and efficient aircraft and performs much of its own maintenance and overhaul
work.

Historically, the Company has relied on generating much of its revenues by use
of a "through fare" arrangement with its major code-sharing partners. A "through
fare" is a combined fare offered to passengers who connect to Mesa from a major
code-sharing partner and vice versa. Mesa is paid a pro rata portion of the
"through fare." As an alternative to the pro rate arrangements, the Company, in
certain markets, has utilized fee per departure arrangements. A fee per
departure arrangement allows the Company to obtain a fee based on a proprietary
formula for each flight operated. The Company seeks to obtain fee per departure
arrangements in those markets where it deems the arrangement more favorable than
a pro rate agreement.

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

OPERATIONS

Operating Revenues:

Operating revenues decreased by $29.9 million to $99.5 million in the quarter
ended June 30, 1998 from $129.4 million in the quarter ended June 30, 1997. The
revenue decrease was primarily due to a 31.4 % decrease in passengers carried.
Available seat miles ("ASMs") decreased by 17.4 %, and the load factor increased
from 56.0% during the June 30, 1997 quarter to 57.1% for the current quarter.
The primary reason for the decrease in ASM's was the discontinuation of the
Company's United Airlines Express ("United") operations. (See Other Events-
United Operations.)

Operating revenues decreased by $32.5 million to $343.7 million for the
nine-month period ended June 30, 1998 from $376.3 million for the nine-month
period ended June 30, 1997. This decrease was primarily due to the decrease in
the number of passengers carried in this period as compared to the nine months
ended June 30, 1997 as explained above, including the cessation of the United
Express operations and independent jet operations in Ft. Worth, Texas. The
independent jet operation was discontinued in February 1998 (See "Other
Events--Independent Jet Operation").

Operating Expenses:

Flight Operations:
- -----------------

Flight operations costs decreased by $10.1million to $38.3 million for the
quarter ended June 30, 1998 from the quarter ended June 30, 1997 and decreased
by $2.1 million to $134.0 million for the nine-month period ended June 30, 1998
from the nine-month period ended June 30, 1997. The primary cause of the
decrease for the quarter ended June 30, 1998 from the prior year's comparable
quarter was the reduction in ASM's previously noted. Flight operations expense
on a cost per ASM basis decreased to 7.2(cent) per seat mile for the quarter
ended June 30, 1998 from 7.6(cent) for the quarter ended June 30, 1997 due to
lower fuel costs. For the nine months ended June 30, 1998, the increase in cost
per ASM over the nine-month period ended June 30, 1997 were caused by a $3.4
million increase in pilot salaries, a $5.7 million increase in lease costs for
deployment of the CRJ aircraft into the Company's fleet, and a $2.9 million
increase in pilot training and lodging, all of which was partially offset by a
decrease in fuel costs of $2.8 million.

Maintenance Expense:
- -------------------

Maintenance expense decreased by $3.1million in the quarter ended June 30, 1998
to $20.5 million from $23.6 million in the same quarter of the previous fiscal
year and increased by $.6 million in the nine-month period ended June 30, 1998
to $67.0 million from $66.4 million for the nine-month period ended June 30,
1997. The decrease for the quarter ended June 30, 1998 was due to the reduction
in ASM's partially offset by maintenance of a greater number of CRJ aircraft for
the period from the prior year and higher costs of operating under increased
regulatory oversight as a Part 121 carrier. The increase for the nine-month
period ended June 30, 1998 was primarily due to a provision of $1.1 million in
uncollectible warranty and insurance claims, a $0.5 million increase as a result
of the higher cost of operating under greater regulatory oversight, and
maintenance of a greater number of CRJ aircraft.

Aircraft and Traffic Service Expense:
- ------------------------------------

Aircraft and traffic service expense decreased by $7.3 million to $14.0 million
during the quarter ended June 30, 1998 from $21.3 million in the comparable
quarter of the previous fiscal year. Aircraft and traffic service expense
decreased by $5.6 million to $57.5 million for the nine-month period ended June
30, 1998 from $63.1 million for the nine-month period ended June 30, 1997. The
decrease for the 


                                       9

   10

quarter ended June 30, 1998 was primarily due to reduced ASM's
and additional rent and landing fee reductions due to the closure of the
Company's United Express operations in Denver, which has some of the highest
rents and landing fees in the Company's system. The decrease for the nine-month
period ended June 30, 1998 was due to reduced ASM's, partially offset by
increased charges for reaccommodation and lost baggage costs from flight
cancellations caused by crew scheduling difficulties and training delays.

Promotion and Sales:
- -------------------

Promotion and sales expense decreased $6.0 million to $14.2 million for the
quarter ended June 30, 1998 and decreased by $6.2 million to $49.5 million for
the nine-month period ended June 30, 1998 over the three-month and nine-month
periods ended June 30, 1997, respectively. The primary reason for these
decreases was a significant decline in the number of passengers carried and a
reduction in commissions paid to travel agents, as a result of fewer passengers
and a lower commission rate.

General and Administrative Expense:
- ---------------------------------

General and administrative expense increased by $.6 million for the three-month
period ended June 30, 1998 to $6.3 million as compared to the quarter ended June
30, 1997 and increased by $3.4 million to $21.8 million for the nine-month
period ended June 30, 1998 as compared to the nine-month period ended June 30,
1997. The primary causes of the increase for the quarter ended June 30, 1998
were $0.4 million increase in health insurance claims, and $0.2 million increase
in property and casualty insurance. The primary causes of the increase for the
nine-month period ended June 30, 1998 was a $0.6 million increase in amounts
paid to employees as part of the employee performance bonus plan, a $1.3 million
increase in the amount of health insurance claims paid during the period, a $0.6
million increase in property taxes, and a $0.3 million increase in property and
casualty insurance.

Depreciation, Amortization and Interest Expense:
- -----------------------------------------------

Depreciation and amortization decreased by $2.4 million to $6.2 million for the
quarter ended June 30, 1998 as compared to the quarter ended June 30, 1997 and
by $4.8 million to $20.8 million for the nine-month period ended June 30, 1998
from the comparable periods in the prior year. The primary reason for these
decreases in depreciation and amortization was the writedown of the Denver
system intangible assets as of September 30, 1997. Interest expense declined by
$1.8 million to $5.2 million during the quarter ended June 30, 1998 from $7.0
million during the similar period in the prior fiscal year and by $2.4 million
to $18.2 million for the nine-month period ended June 30, 1998 from the
comparable period in the prior year. The decrease was due to lower outstanding
principal loan balances as a result of the retirement of aircraft.

Other Operating Items:
- ---------------------

During the nine-months ended June 30, 1998, the Company recognized a $4.0
million loss provision related to the discontinuation of its independent jet
operations in Ft. Worth, Texas. The Company also recognized a $2.5 million loss
provision related to anticipated settlement costs of a shareholder class action
lawsuit. See, Part II, Item 1. "Legal Proceedings." The Company also recognized
a $33.9 million loss provision related to the discontinuation of service under
the Mesa Airlines, Inc. ("MAI") code-sharing agreement with United Airlines,
Inc. ("UAL"). See, "Other Events--United Airlines."

Other Non-Operating Income:
- --------------------------



                                       10
   11

In January 1998, Mesa sold its remaining investment in America West Airlines,
Inc. ("AWA") comprised of 100,000 Class A shares, 200,000 Class B shares and
warrants to purchase approximately 800,000 Class B shares. Mesa received cash of
approximately $11.1 million and recognized non-operating income of approximately
$4.5 million on the sale of these securities.


LIQUIDITY AND CAPITAL RESOURCES

The Company's cash balance of $50.4 million at June 30, 1998 included $2.4
million of cash restricted for the issuance of letters of credit, and $11.5
million held by WestAir Commuter Airlines, Inc. ("WestAir").

Mesa had receivables of $30.2 million at June 30, 1998 which consisted primarily
of amounts due from code-sharing partner US Airways, Inc. ("US Airways"). Under
the terms of the US Airways code-sharing agreement, Mesa receives a substantial
portion of its revenues through the Airline Clearing House. Historically, the
Company has enjoyed cash flow sufficient to meet its needs. However, UAL has
terminated all of its code-sharing agreements with the Company. Such action
could have a material negative impact on the financial position and cash flow of
the Company, particularly if the Company cannot re-deploy its United Express
aircraft on other operating routes, or alternatively, sell the aircraft or
return them to the lessors. Management's belief that the Company will have
adequate cash flow to meet its operating needs is a forward-looking statement.
The Company may have less cash flow than anticipated in the event of a
substantial decrease in the number of routes allocated to MAI under its
code-sharing agreements with US Airways and America West Airlines, failure to
sell, dispose of, or redeploy its assets associated with United Express
operations in a timely manner, 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.

On March 1, 1998, the Company's $20 million secured line of credit expired under
its terms and the bank declined to renew it. The Company has been approved by
another financial institutions to provide a secured $20 million line of credit.
There is presently no balance outstanding under this line of credit.

As of June 30, 1998, Mesa was not in compliance with some of the secured debt
covenants required by a bank credit agreement; however, the bank has waived
compliance with such covenants. The Company believes it will either maintain
compliance or obtain waivers of compliance with its present debt covenants
through September 30, 1998. Management's belief that it will maintain compliance
with its present debt covenants is a forward-looking statement. Compliance may
be adversely impacted in the event of the termination or renegotiation of one or
more code-sharing agreements, a substantial decrease in the number of routes
allocated to MAI under its code-sharing agreements with US Airways, failure to
dispose of or redeploy assets associated with its United Express operations,
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 settlement of
existing or potential litigation.

At June 30, 1998, the Company had aggregate indebtedness of approximately $259.4
million payable to various parties under promissory notes issued in connection
with the purchase of aircraft. The notes have interest rates ranging from 6.66%
to 7.87% with maturities through December 2011. In addition, the Company has
significant lease obligations on other operating and non-operating aircraft.
These leases are classified as operating leases and therefore are not reflected
as liabilities in the accompanying balance sheet. At June 30, 1998, 67 aircraft
were leased by the Company with terms extending through



                                       11

   12

June 2016. Total lease expense for the nine-month period ended June 30, 1998
amounted to $31.8 million.

Mesa has ordered 32 CRJ aircraft for use in its AmericaWest Express operation in
Phoenix, Arizona, as USAirways Express on the East Coast and in other markets
that management believes have the potential for profitable operations. As of
June 30, 1998, the Company had received sixteen of the 32 CRJ aircraft on order
and expects to take delivery of the remaining 16 aircraft by the end of 1999.
The Company has options for an additional 16 CRJ aircraft with a delivery
schedule of one per month beginning June 2000. The value of these 32 CRJ
aircraft is approximately $640 million. The expected delivery schedule of
aircraft is a forward-looking statement which could significantly differ based
on manufacturer's delivery delays, among other factors.

The Company's wholly owned subsidiary, WestAir Holding, Inc. ("WHI"), owns
WestAir Commuter Airlines, Inc. ("WestAir"), a certificated air carrier and
Regional Aircraft Services, Inc. ("RAS"), an aircraft equipment repair service
company. WestAir had a total of 22 Embraer Brasilia aircraft leased from various
lessors along with the 21 Jetstreams which are currently parked and not being
utilized in WestAir's operations. WestAir made lease payments for all 43
aircraft only through May 31, 1998, the expiration date of WestAir's
code-sharing agreement with UAL. Failure to make lease payments constituted a
default under the lease agreements. The aircraft lessors have the right to
exercise liens each lessor has on particular aircraft.

If the aircraft provide insufficient collateral for the remaining lease
payments, it is the belief of management that while the various lessors may seek
recovery of any deficiency from WestAir (or WHI, as the various lease contracts
permit) that they will have no right to seek any recovery of deficiencies from
Mesa Air Group, Inc. Management's belief that the various aircraft lessors will
have no right of recovery against Mesa Air Group, Inc. itself is a
forward-looking statement which could materially differ based on the
interpretation of lease agreements and other documents entered into between
WestAir and/or WHI and the lessors by a court or an arbitrator, as the case may
be.

WestAir's operations are being liquidated due to the expiration of the UAL
code-sharing agreement. The remaining assets and liabilities of WHI and its
subsidiaries are included in the consolidated financial statements of Mesa Air
Group, Inc. as of June 30, 1998. It is unlikely that any assets of WestAir will
remain for distribution to WHI and, ultimately, Mesa Air Group, Inc.

Management of the Company recognizes the need to ensure its operations will not
be adversely impacted by Year 2000 software failure and that the Company's
computer systems and applications must function properly beyond 1999. The
Company is conducting the analysis necessary to determine the potential Year
2000 risk and until completion of such analysis will not know the cost to the
Company of potential Year 2000 software failure. Although the Company cannot
presently estimate the costs associated with Year 2000 software failure, such
costs will be expensed as incurred.

The Company recognizes that its business is reliant upon the systems and
applications of third parties and will conduct an assessment of the potential
risks. However, there can be no assurance that the systems and applications of
other parties upon which the Company's business relies will be converted on a
timely basis. The Company's business, financial condition, or results of
operations could be materially adversely affected by the failure of its systems
and applications or the failure of those systems operated by other parties to
properly operate or manage dates beyond 1999.

OTHER EVENTS

United Airlines, Inc.

As a result of termination by UAL of the West Air and MAI Code-Sharing
Agreements on April 22 and May 31, 1998 respectively, the Company incurred a
loss provision totaling $106 million to provide for costs to dispose of certain
aircraft, equipment, and other costs to shut down the entire United Express
system. Should the Company fail to locate purchasers for its excess Beechcraft
1900D aircraft or redeploy its Dash 8-200 aircraft utilized in the MAI United
Express system in a timely manner, the $106 million loss provision may be
inadequate and subject to a material increase. The Company anticipates flying
the Dash 8-200 aircraft under an agreement with AWA (see America West Airlines,
Inc. discussion). Management of the Company believes that it will incur
approximately $15 to $20 million of net cash expenditures during the 12-month
period subsequent to May 31, 1998 as a result of the termination of its MAI and
WestAir code-sharing agreements. WestAir spent approximately $1.7 million in the
period from June 1, 1998 through July 31, 1998 on wind down activities. The
estimated net cash expenditure is a forward-looking statement which could
materially change as a result of the ultimate cost to park the WestAir fleet, or
the failure to sell or dispose of excess aircraft in a timely manner.

US Airways, Inc.

Mesa has entered into a marketing agreement with US Airways in which it will
initially operate 12 CRJ aircraft in its USAirways Express operation. The
Company began USAirways Express CRJ service on January 19, 1998, with flights
between Philadelphia, Pennsylvania and Birmingham, Alabama; St. Louis, Missouri;
Cincinnati, Ohio; and Newburgh, New York. Other cities to be served include
Charlotte, North Carolina; Washington, D.C.; Toronto, Canada; Little Rock,
Arkansas; Charleston, West Virginia; Raleigh Durham, North Carolina; Boston,
Massachusetts; Milwaukee, Wisconsin; White Plains, New York; and Tallahassee,
Florida. All of this service is to be provided pursuant to a fee per departure
arrangement. There are 12 CRJ aircraft operating in the US Airways Express
system as of August 1, 1998.

America West Airlines, Inc.

The terms of the Company's code-sharing agreement with AWA provide for a minimum
controllable flight completion factor for any consecutive two-month period.
Primarily as a result of flight crew shortages in December 1997 and January
1998, MAI's controllable flight completion factor fell below the minimum and AWA
issued the Company a notice of termination. In early February 1998, MAI resolved
its crew shortages with AWA and its controllable completion factor exceeded the
minimum requirement in February 1998 through April 1998. Subsequent to the
termination by AWA of the code-sharing agreement, AWA and Mesa entered into an
interim agreement to continue Mesa operations as America West Express through
September 10, 1998.

The Company entered into a new six-year agreement with AWA to provide expanded
regional airline service as America West Express. The new agreement calls for
the addition of eleven 37-passenger turboprop aircraft and ten regional jets by
the end of 1999, with options to continue to expand both fleets in the year 2000
and 2001. This will more than double the size of the America West operation over
the next twelve months. The Company will be compensated for these markets under
a modified fee per departure arrangement.

PART II.      OTHER INFORMATION

Item 1.       Legal Proceedings

              During 1994, seven shareholder class action complaints were filed
              in the United States District Court for the District of New Mexico
              against Mesa, certain of its present and former corporate officers
              and directors, its independent auditor, and certain underwriters
              who participated in Mesa's June 1993 public offering of Common
              Stock. During October 1995, the court certified a class consisting
              of persons who purchased Mesa stock between January 28, 1993 and
              August 5, 1994. These complaints were consolidated by court order,
              and, after the court granted in part a motion to dismiss in May
              1996, a third amended consolidated complaint was filed alleging
              that during the class period the defendants caused or permitted
              Mesa to issue publicly misleading financial statements and other
              misleading statements in the registration statement for the June
              1993 public offering, annual and quarterly reports to
              shareholders, press releases and interviews with securities
              analysts.

              In May 1998, the Company entered into a memorandum of
              understanding with the plaintiffs to settle the litigation. While
              the Company and its corporate officers and directors believe they
              have substantial and meritorious defenses against the plaintiff's
              allegations and have defended their position vigorously, they have
              agreed to a settlement to avoid ongoing litigation. The memorandum
              of understanding provides for a total of $8 million to be paid to
              the class plaintiffs on behalf of the defendants. The Company will
              pay a substantial portion of this settlement. The settlement still
              must be approved by the Court following notification of the Class.
              The Company intends to utilize funds reserved for the defense of
              the case as its contribution towards the settlement.

              In June 1997, UAL filed a complaint in the United States District
              Court for the Northern District of Illinois against two
              subsidiaries of the Company, Mesa Airlines, Inc. ("MAI") and
              WestAir, 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



                                       14

   15
              "increase, decrease, or in any other way adjust the flight 
              frequencies, or 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. MAI and WestAir dispute the principal contentions in
              UAL's complaint, and unless a satisfactory negotiated resolution
              is achieved, intend to defend their position 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
              to the business of MAI and WestAir which have been incurred.

              In addition, Mesa and WestAir have counter claimed against UAL 
              and SkyWest Airlines. 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 in
              leading to the non-renewal of the WestAir agreement. The Company
              is seeking substantial damages against each defendant.

              In July 1998, Jet Acceptance Corporation ("Jet Acceptance") filed
              suit against Mesa and WestAir in the United States District Court
              for the Northern District of California. The suit seeks damages
              from WestAir for non-payment of leases for Jetstream 31 aircraft
              leased by WestAir and also claims damages against Mesa for
              alleged fraudulent conveyances and the receipt of illegal
              dividends. Jet Acceptance claims damages in the amount of
              approximately $16.5 million. Jet Acceptance seeks to hold Mesa
              liable for the WestAir leases on an "alter ego" or "piercing the
              corporate veil" theory. Mesa denies the allegations. Jet
              Acceptance has applied for and received a court-ordered
              attachment of WestAir's assets. The Company intends to vigorously
              defend this suit.

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

              In the belief of management, based upon information at this time,
              the ultimate outcome of all the proceedings and claims pending
              against Mesa other than those with UAL and Jet Acceptance
              referred to above is not expected to have a material adverse
              effect on Mesa's consolidated financial position. It is too early
              to determine the impact on Mesa's financial position of the
              litigation with UAL and Jet Acceptance.

              The belief that UAL has breached its code-sharing agreements with
              MAI and WestAir and the belief that the ultimate outcome of
              certain of the proceedings and claims pending against Mesa will
              favorably be resolved are forward-looking statements which could
              materially differ as a result of the determination of a judge or
              jury.

Item 5.       The Company expects to hold its next annual meeting in March 1999.
              Shareholder proposals to be included in the Company's proxy
              materials and form of proxy must be received by the Company no
              later than September 30, 1998. To be included, proposals must be
              proper under law and comply with the rules and regulations of the
              U.S. Securities and Exchange Commission. Shareholders desiring to
              present proposals at the 1999 annual meeting that are




                                       15

              not to be included in the Company's proxy materials and form of
              proxy must provide the Company with notice no later than December
              1, 1998.
