                    UAL Corporation and Subsidiary Companies
             Notes to Consolidated Financial Statements (Unaudited)

The Company
- -----------

           UAL Corporation ("UAL") is a holding company whose principal
subsidiary is United Air Lines, Inc. ("United").

Interim Financial Statements
- ----------------------------

           The consolidated financial statements included herein have been
prepared pursuant to the rules and regulations of the Securities and Exchange
Commission. Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted pursuant to or as permitted by such
rules and regulations, although UAL believes that the disclosures are adequate
to make the information presented not misleading. In management's opinion, all
adjustments (which include only normal recurring adjustments) necessary for a
fair presentation of the results of operations for the three- and six-month
periods have been made. These financial statements should be read in conjunction
with the consolidated financial statements and footnotes thereto included in
UAL's Annual Report on Form 10-K for the year 1998.

Employee Stock Ownership Plans
- ------------------------------

           Pursuant to amended labor agreements which provide for wage and
benefit reductions and work-rule changes which commenced July 1994, UAL has
agreed to issue convertible preferred stock to employees. Note 2 of the Notes to
Consolidated Financial Statements in the 1998 Annual Report on Form 10-K
contains additional discussion of the recapitalization, stock to be issued to
employees and the related accounting treatment. Since January 1, 1999, an
additional 1,536,986 shares of Class 1 and Class 2 ESOP Preferred Stock have
been committed to be released.

Income Taxes
- ------------

           The provisions for income taxes are based on the estimated annual
effective tax rate, which differs from the federal statutory rate of 35%
principally due to state income taxes, dividends on ESOP Preferred Stock and
certain nondeductible items.

Per Share Amounts
- -----------------

           Basic earnings per share were computed by dividing net income
available to common stockholders by the weighted-average number of shares of
common stock outstanding during the year. In addition, diluted earnings per
share amounts include potential common shares including common shares issuable
upon conversion of ESOP shares committed to be released.

         Included in 1999 Domestic, Pacific, Latin American and Atlantic fully
distributed earnings before income taxes is $393 million, $134 million, $36
million and $106 million, respectively, of pre-tax gain on the sale of Galileo
stock.

Investments in Affiliates
- -------------------------

         In June 1999, United sold 17,500,000 common shares of Galileo
International, Inc. ("Galileo") in a secondary offering for $766 million,
resulting in a pre-tax gain of approximately $669 million. This sale reduced
United's holdings in Galileo from 32 percent to approximately 17 percent,
requiring United to discontinue the equity method of accounting for its
investment in Galileo. United has classified its remaining 15,940,000 shares of
Galileo common stock as available-for-sale. The market value of these shares at
June 30, 1999 ($852 million) is reflected in Investments in Affiliates on the
balance sheet and the market value over United's investment is classified
net-of-tax ($496 million) in accumulated other comprehensive income. Equity
earnings in Galileo were $17 million and $18 million for the three-month periods
ended June 30, 1999 and 1998, respectively and $40 million and $38 million for
the six-month periods ended June 30, 1999 and 1998, respectively.

         United owns approximately 2.1 million depository certificates in
Equant, a provider of international data network services to multinational
businesses and a single source for global desktop communications. Each
depository certificate represents a beneficial interest in an Equant common
share. These depository certificates are currently subject to certain
transferability restrictions and are carried at their original cost, which is
nominal. At June 30, 1999, the estimated fair value of United's investment in
Equant is approximately $198 million.

customers. United has a minority interest in GetThere.com consisting of
convertible preferred stock, warrants and options. United's holdings are
convertible into an approximate 25 percent interest in GetThere.com. United
accounts for its investment in GetThere.com using the equity method of
accounting.

           In July 1999, United and Buy.com agreed to form a joint venture
(BuyTravel.com) to sell travel on all major airlines, as well as hotels, car
rentals and cruises via the Internet. Both United and Buy.com will have a 50
percent interest in BuyTravel.com. United will account for its investment in
BuyTravel.com using the equity method of accounting.

Other Comprehensive Income

         Total comprehensive income for the three- and six-month periods ending
June 30, 1999 was $1,164 million and $1,242 million, respectively, compared to
$281 million and $342 million for the three- and six-month periods ending June
30, 1998, respectively. Other comprehensive income consisted of net unrealized
gains (losses) on securities of $495 million for the three- and six-month
periods ending June 30, 1999 and $(1) million for the three- and six-month
periods ending June 30, 1998, respectively.

         Effective April 1, 1999, United revised its estimate of depreciable
lives on certain of its aircraft types to 25 years and increased the residual
value of these aircraft to 10 percent. Previously, lives on these aircraft
ranged from 20 to 23 years and residual values ranged from 4.5 percent to 7.3
percent. United also shortened the estimated depreciable lives on certain other
aircraft from 10 years to 4 years. These changes did not have a significant
impact on United's results of operations.

Contingencies and Commitments

           UAL has certain contingencies resulting from litigation and claims
(including environmental issues) incident to the ordinary course of business.
Management believes, after considering a number of factors, including (but not
limited to) the views of legal counsel, the nature of contingencies to which UAL
is subject and its prior experience, that the ultimate disposition of these
contingencies is not expected to materially affect UAL's consolidated financial
position or results of operations.

           At June 30, 1999, commitments for the purchase of property and
equipment, principally aircraft, approximated $5.5 billion, after deducting
advance payments. An estimated $1.3 billion will be spent during the remainder
of 1999, $2.0 billion in 2000, $1.9 billion in 2001 and $0.3 billion in 2002 and
thereafter. The major commitments are for the purchase of B777, B747, B767,
B757, A320 and A319 aircraft, which are scheduled to be delivered through 2002.

        OF OPERATIONS
        -------------


LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

           UAL's total of cash and cash equivalents and short-term investments
was $1.4 billion at June 30, 1999, compared to $815 million at December 31,
1998. Cash flows from operating activities for the six-month period amounted to
$1.6 billion. Financing activities included principal payments under debt and
capital lease obligations of $456 million and $165 million, respectively and $25
million in aircraft lease deposits. Additionally, the Company issued, and
subsequently retired, $286 million in debt during the period to finance the
acquisition of aircraft.

           Property additions, including aircraft and aircraft spare parts,
amounted to $1.3 billion, while property dispositions resulted in proceeds of
$141 million. In the first six months of 1999, United took delivery of two A320,
eight A319, three B777, two B757, two B767 and six B747 aircraft. Eleven of the
aircraft were purchased and 12 were acquired under capital leases. In addition,
United acquired two B727 aircraft off-lease during the first six months and
retired four DC10 and three B747 aircraft.

           United has certain non-core investments with market values
substantially in excess of their acquisition cost. It is United's policy to
monetize its non-core investments. In June 1999, United sold 17.5 million shares
of common stock of Galileo receiving aggregate proceeds of $766 million. These
proceeds will be used to achieve United's financial goals which include
investing in its core business, improving its credit worthiness and returning
cash to shareholders.

           At June 30, 1999, commitments for the purchase of property and
equipment, principally aircraft, approximated $5.5 billion, after deducting
advance payments. Of this amount, an estimated $1.3 billion is expected to be
spent during the remainder of 1999. For further details, see "Contingencies and
Commitments" in the Notes to Consolidated Financial Statements.

RESULTS OF OPERATIONS
- ---------------------

           Summary of Results

           UAL's earnings from operations were $579 million in the first six
months of 1999, compared to operating earnings of $593 million in the first six
months of 1998. UAL's net earnings before an extraordinary loss on early
extinguishment of debt were $750 million ($6.33 per share, diluted), compared to
net earnings of $343 million during the same period of 1998 ($2.80 per share,
diluted).

           In the second quarter of 1999, UAL's earnings from operations were
$433 million compared to operating earnings of $470 million in the second
quarter of 1998. UAL had net earnings in the 1999 second quarter of $672 million
($5.78 per share, diluted) before the extraordinary loss, compared to net
earnings of $282 million in the same period of 1998 ($2.44 per share, diluted).


   13

           The 1999 earnings include a pre-tax gain of $669 million ($3.95 per
share for the six-month period; $3.88 per share for the quarter) on the sale of
a portion of United's investment in Galileo (see "Investments in Affiliates" in
the Notes to Consolidated Financial Statements).

           Management believes that a more complete understanding of UAL's
results may be gained by viewing them on a pro forma, "Fully Distributed" basis.
This approach considers all ESOP shares which will ultimately be distributed to
employees throughout the ESOP (rather than just the shares committed to be
released) to be immediately outstanding and thus Fully Distributed. Consistent
with this method, the ESOP compensation expense is excluded from Fully
Distributed net earnings and ESOP convertible preferred stock dividends are not
deducted from earnings attributable to common stockholders. A comparison of
results reported on a Fully Distributed basis to results reported under
generally accepted accounting principles (GAAP) is as follows (in millions,
except per share):

           The current relationship of earnings and earnings per share as
computed on a GAAP basis versus a Fully Distributed basis may not be
representative of the relationship in future periods because of various factors.
These factors include, but are not limited to, the dependence of ESOP
compensation expense on the common stock price; trends and commitments with
respect to wages; and the convergence of shares assumed outstanding under the
GAAP basis as compared to the Fully Distributed basis.

           Specific factors affecting UAL's consolidated operations for the
second quarter and first six months of 1999 are described below.



   14


         Second Quarter 1999 Compared with Second Quarter 1998
         -----------------------------------------------------

         Operating revenues increased $99 million (2%) and United's revenue per
available seat mile (unit revenue) decreased 1% to 10.19 cents. Passenger
revenues increased $41 million (1%) partially due to a slight increase in
United's revenue passenger miles. Strong domestic performance provided an
overall increase in yield from 12.58 to 12.69 cents. The slight increase in
revenue passenger miles in conjunction with system available seat miles
increasing 4% reduced passenger load factor to 70.1% as compared to 72.6%. The
following analysis by market is based on information reported to the U.S.
Department of Transportation:




                                        Increase (Decrease)
                                        -------------------

                   ---------------    --------------     ----------------------
                                                
Domestic                  6%                1%                     3%
Pacific                 (11%)             (13%)                    2%
Atlantic                 20%               17%                    (9%)
Latin America            (6%)              (1%)                   (6%)
      System              4%                -%                     1%



           Despite capacity reductions in the region, weak demand for travel in
the Pacific markets led to a decline in load factor. The improvements in Pacific
yield were offset by a 2-point decline in load factor resulting in flat unit
revenue. Yields in other international markets continue to be impacted by weak
economies, a negative pricing environment and excess industry capacity.

           Cargo revenues increased $3 million (1%) on increased freight ton
miles of 5%. Freight yield decreased 3% and mail yield decreased 2% for a total
decrease in cargo yield of 3% for the period. Other operating revenues increased
$55 million (20%) due to increases in frequent flyer program partner-related
revenues and fuel sales to third parties.

           Operating expenses increased $136 million (3%) while United's cost
per available seat mile decreased 0.2%, from 9.25 cents to 9.23 cents, including
ESOP compensation expense. Without the ESOP compensation expense, United's cost
per available seat mile would have been 8.82 cents, an increase of 1% from the
1998 second quarter. ESOP compensation expense decreased $50 million (22%),
reflecting a decrease in the estimated average fair value of ESOP stock
committed to be released to employees. Salaries and related costs increased $120
million (9%) due to ESOP mid-term wage adjustments which took place in July 1998
and to increased staffing in certain customer-contact positions. Aircraft
maintenance increased $35 million (25%) due to an increase in heavy maintenance
visits. Depreciation and amortization increased $21 million (11%) due to an
increase in the number of owned aircraft and losses on disposition of aircraft
partially offset by changes in depreciable lives on certain aircraft. Other
expenses increased $43 million (8%) largely due to costs associated with fuel
sales to third parties. Commissions decreased $37 million (11%) due to a change
in the commission structure implemented in the third quarter of 1998 and lower
commissionable revenues. Aircraft fuel decreased $15 million (3%) as a 6%
decrease in the cost of fuel from 58.0 cents to 54.5 cents a gallon more than
offset increased consumption.

           Other expense amounted to $50 million in the second quarter of 1999
(excluding the gain on the Galileo transaction - see "Investments in Affiliates"
in the Notes to Consolidated


   15

Financial Statements) compared to $41 million in the second quarter of 1998.
Interest capitalized decreased $13 million (43%) as a result of lower advance
payments on the acquisition of aircraft and a lower weighted average interest
rate. Miscellaneous, net included foreign exchange gains of $2 million in the
second quarter of 1999 compared to foreign exchange losses of $7 million in the
second quarter of 1998.

           Six Months 1999 Compared with Six Months 1998
           ---------------------------------------------

           Operating revenues increased $205 million (2%) and United's revenue
per available seat mile (unit revenue) decreased 1% to 10.01 cents. Passenger
revenues increased $155 million (2%) despite a slight decrease in yield from
12.67 to 12.61 cents. Available seat miles across the system were up 3%
resulting in a passenger load factor 69.6%, down 0.3 points. The following
analysis by market is based on information reported to the U.S. Department of
Transportation:

           Despite capacity reductions in the region, weak demand for travel in
Pacific markets continues to negatively impact yields. Yields in other
international markets continue to be impacted by weak economies, a negative
pricing environment and excess industry capacity.

           Cargo revenues decreased $4 million (1%) despite increased freight
ton miles of 3%. A 2% lower freight yield and a 4% lower mail yield resulted in
a 3% decrease in cargo yield for the period. Other operating revenues increased
$54 million (10%) due to increases in frequent flyer program partner-related
revenues and fuel sales to third parties.

           Operating expenses increased $219 million (3%) and United's cost per
available seat mile decreased slightly, from 9.38 cents to 9.36 cents, including
ESOP compensation expense. Without the ESOP compensation expense, United's cost
per available seat mile would have been 8.94 cents, an increase of 2% from the
1998 six-month period. ESOP compensation expense decreased $126 million (26%),
reflecting the decrease in the estimated average fair value of ESOP stock
committed to be released to employees. Purchased services increased $46 million
(6%) due to increases in computer reservations fees and Y2K expenses.
Depreciation and amortization increased $41 million (11%) due to an increase in
the number of owned aircraft and losses on disposition of aircraft partially
offset by changes in depreciable lives of certain aircraft. Salaries and related
costs increased $220 million (8%) due to ESOP mid-term wage adjustments which
took place in July 1998 and increased staffing in certain customer-contact
positions. Aircraft maintenance increased $57 million (19%) due to an increase
in heavy maintenance visits. Commissions decreased $71 million (11%) due to a
change in the commission structure implemented in the third quarter of 1998 as
well as a slight decrease in commissionable revenues. Aircraft fuel decreased
$61 million (7%) due to a 9% decrease in the cost of fuel from 59.8 cents


   16

to 54.4 cents a gallon. Aircraft rent decreased $14 million (3%) due to aircraft
refinancing completed in the first quarter of 1998.

           Other expense amounted to $72 million in the first six months of 1999
(excluding the gain on the Galileo transaction - see "Investments in Affiliates"
in the Notes to Consolidated Financial Statements) compared to $68 million in
the first six months of 1998. Interest capitalized decreased $20 million (36%)
as a result of lower advance payments on the acquisition of aircraft and a lower
weighted average interest rate. Miscellaneous, net included foreign exchange
gains of $23 million in 1999 compared to foreign exchange losses of $11 million
in 1998.


LABOR AGREEMENTS
- ----------------

           On May 27, 1999, United's public contact employees (primarily
customer service and reservations sales and service representatives) ratified
the tentative agreement between the Company and the International Association of
Machinists and Aerospace Workers ("IAM"). The contract provides for an
across-the-board wage increase of 5.5 percent effective April 13, 2000. In
addition, certain employees hired after January 1, 1994 received an immediate
14.5% pay increase and benefits comparable to other affected employees. Terms of
the contract are amendable in July 2000.

FINANCIAL INSTRUMENTS AND RISK MANAGEMENT
- -----------------------------------------

           During the second quarter, United reinstated its jet fuel hedging
program. This program now consists of hedging 100% of probable jet fuel
requirements with crude oil purchased call options and fixed price jet fuel
contracts. The purchased call options have been designated as a hedge of
anticipated jet fuel purchases; accordingly, gains or losses on hedge positions
are recognized upon contract expiration as a component of aircraft fuel
inventory. At June 30, 1999, United has purchased call options on approximately
1.4 billion gallons of fuel products, which represents 69% of United's
anticipated third and fourth quarter fuel requirements and 8% of its expected
2000 fuel requirements. At June 30, 1999, United has contracted to purchase
approximately 8% of its anticipated third and fourth quarter fuel requirements.
As of July 31, 1999, United has hedged 100% of its probable third and fourth
quarter jet fuel requirements.

UPDATE ON YEAR 2000 READINESS*
- ------------------------------

         Readers should refer to "Update on Year 2000 Readiness" in Management's
Discussion and Analysis of Financial Condition and Results of Operations in the
1998 Annual Report on Form 10-K for background information.

         IT systems. The Company has substantially completed the remediation,
initial system testing and business process integration testing of mainframe
hardware and software and other hardware infrastructure including voice and data
networks and all internally developed IT software applications.

         Non IT systems. The remediation and testing of date-sensitive, critical
non-IT systems is complete. Re-testing of mission critical systems will continue
throughout the year.
   17


         Critical Business Partners. The Company has contacted all of its
"Strategic" and "Preferred" Critical Business Partners. United believes these
partners have a satisfactory Year 2000 program in place.

         The results of the study undertaken by the Air Transport Association
("ATA") to determine the process domestic airports are using to achieve Year
2000 readiness, shows that most large domestic airports have made substantial
progress towards being Year 2000 ready. A similar project undertaken by the
International Air Transport Association ("IATA") shows that although most
international airports have made progress during the past few months, certain
key airports are behind schedule.

         The Company's aircraft manufacturers have concluded that there are no
safety of flight issues related to the Year 2000 date rollover as to their
aircraft.

         Concurrent with ensuring that all the systems will be remediated and
tested for the Year 2000 date rollover, the Company continues to develop
contingency plans for all mission critical business processes. These contingency
plans, together with the airline readiness reviews planned during the third
quarter of 1999, are designed to reduce the likelihood that the Company's
operations will be interrupted by Year 2000 related issues. In addition, the
Company will set up a corporate Command Center to monitor and respond to
potential Year 2000 issues worldwide.

         The Company anticipates that project costs will range between $85 and
$90 million, with approximately 34% being capitalized. To date the Company has
incurred $53 million in project costs ($37 million in expense and $16 million in
capital). During 1999, the Company incurred $25 million in project costs ($14
million in expense and $11 million in capital). During the third quarter, the
Company plans to spend up to $17 million on the replacement of desktop
computers.

OUTLOOK FOR 1999*
- -----------------

         The Company expects its 1999 system capacity to grow 2%, which is less
than the forecasted industry capacity growth rate. Unit revenues are estimated
to range between zero and 1% higher than 1998.

         Unit costs for 1999, excluding ESOP charge, are estimated to range
between 1.5% and 2% higher than 1998, based on an average fuel price of
approximately 59 cents per gallon including taxes. Among the factors affecting
costs will be the cap in international commissions instituted last year and the
level of spending on Year 2000 (see "Update on Year 2000 Readiness").

         The following guidance pertaining to fully distributed earnings per
share is consistent with the corresponding guidance set forth in UAL's Form 8-K
dated June 7, 1999. The Company forecasts 1999 earnings to range between $9.00
and $11.00 per fully distributed share, with its internal goal being to earn
$11.00 per fully distributed share. The forecasted range of fully distributed
earnings per share excludes the impact of the gain on sale of 17.5 million
shares of Galileo. The Company's earnings per share performance will be helped
by the reduction in share count stemming from the $500 million common stock
repurchase program completed earlier this year.
   18

           The Company anticipates a modest year-over-year increase in unit
revenue for the third quarter, based on continued strong domestic economic
performance and gradual improvements in the Pacific. Given this positive
environment, the Company expects third quarter fully distributed earnings per
share to range between $3.60 and $4.00.

           Management's Discussion and Analysis of Financial Condition and
Results of Operations contains sections with forward-looking statements which
are identified with an asterisk (*). Information included in the "Update on Year
2000 Readiness" and the "Outlook for 1999" sections is forward-looking and
actual results could differ materially from expected results. Factors that could
significantly impact expected capacity, international revenues and profits, unit
revenues, fully distributed unit costs, fuel prices and fully distributed
earnings per share include: industry capacity decisions, the airline pricing
environment, fuel prices, the success of the Company's cost-control efforts,
actions of the U.S., foreign and local governments, willingness of customers to
travel, the Asian economic environment and travel patterns, foreign currency
exchange rate fluctuations, the stability of the U.S. economy, UAL common stock
price fluctuations, the economic environment of the airline industry and the
global economic environment. Some factors that could significantly impact the
Company's expected Year 2000 readiness and the estimated cost thereof include:
the results of the system integration testing and the sufficiency and
effectiveness of the Year 2000 programs of the Company's critical business
partners, including domestic and international airport authorities, aircraft
manufacturers and the Federal Aviation Administration, to achieve Year 2000
readiness.
