UNITED CONTINENTAL HOLDINGS, INC.,

UNITED AIR LINES, INC. AND CONTINENTAL AIRLINES, INC.

COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

United Continental Holdings, Inc. (together with its consolidated subsidiaries, “UAL”) is a holding company and its principal, wholly-owned subsidiaries are United Air Lines, Inc. (together with its consolidated subsidiaries, “United”) and Continental Airlines, Inc. (together with its consolidated subsidiaries, “Continental”). All significant intercompany transactions are eliminated.

This Quarterly Report on Form 10-Q is a combined report of UAL, United and Continental. We sometimes use the words “we,” “our,” “us,” and the “Company” for disclosures that relate to all of UAL, United and Continental. As UAL consolidates United and Continental for financial statement purposes, disclosures that relate to United and Continental activities also apply to UAL. When appropriate, UAL, United and Continental are named specifically for their related activities and disclosures.

Interim Financial Statements. The UAL, United and Continental unaudited condensed consolidated financial statements shown here have been prepared as required by the U.S. Securities and Exchange Commission (the “SEC”). Some information and footnote disclosures normally included in financial statements that comply with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted as permitted by the SEC. The financial statements include all adjustments, including normal recurring adjustments and other adjustments, which are considered necessary for a fair presentation of the Company’s financial position and results of operations. Certain prior year amounts have been reclassified to conform to the current year’s presentation. These reclassifications were made to conform the financial statement presentation of UAL, United and Continental. The UAL, United and Continental financial statements should be read together with the information included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011 (the “2011 Annual Report”). UAL’s quarterly financial data is subject to seasonal fluctuations and historically its second and third quarter financial results, which reflect higher travel demand, are better than its first and fourth quarter financial results.

NOTE 1—FREQUENT FLYER AND PASSENGER REVENUE ACCOUNTING

Frequent Flyer Awards. Effective January 1, 2012, the Company updated its estimated selling price for miles to the contractual rate at which we sell miles to our Star Alliance partners participating in reciprocal frequent flyer programs. This change in estimate has been applied prospectively effective January 1, 2012.

United and Continental account for miles sold and awarded that will never be redeemed by program members, which the Company refers to as “breakage,” using the redemption method. UAL reviews its breakage estimates annually based upon the latest available information regarding redemption and expiration patterns. The Company re-evaluated its population breakage estimates for Continental OnePass miles, which were previously not subject to an expiration policy, and increased the estimate of miles in the population expected to ultimately expire. As a result, the rate at which we recognize redeemed miles has increased.

The Company’s estimate of the expected expiration of miles requires significant management judgment. Current and future changes to expiration assumptions, the expiration policy, program rules or program redemption opportunities may result in material changes to the deferred revenue balance as well as recognized revenues from the Company’s frequent flyer program.

For the three and six months ended June 30, 2012, the combined net impact of these changes to UAL, United and Continental were not material.

NOTE 2—NEW ACCOUNTING PRONOUNCEMENTS

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2011-04 (“ASU 2011-04”), Fair Value Measurement: Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRS. Some of the key amendments to the fair value measurement guidance include the highest and best use and valuation premise for nonfinancial assets, application to financial assets and financial liabilities with offsetting positions in market risks or counterparty credit risk, premiums or discounts in fair value measurement and fair value of an instrument classified in a reporting entity’s shareholders’ equity. Additional disclosures for fair value measurements categorized in Level 3 of the fair value hierarchy include a quantitative disclosure of the unobservable inputs and assumptions used in the measurement, a description of the valuation processes in place, a narrative description of the sensitivity of the fair value to changes in unobservable inputs and interrelationships between those inputs and the level in the fair value hierarchy of items that are not measured at fair value in the consolidated balance sheet but whose fair value must be disclosed. ASU 2011-04 became effective for the Company’s annual and interim periods beginning January 1, 2012, and the required disclosures are disclosed in Note 6 of this report.

NOTE 3—EARNINGS (LOSS) PER SHARE

The table below represents the computation of UAL basic and diluted earnings (loss) per share amounts and the number of securities that have been excluded from the computation of diluted earnings (loss) per share amounts because they were antidilutive (in millions, except per share amounts):

Continental 4.5% Convertible Notes		—			—			12			—
Continental 6% Convertible Junior Subordinated Debentures		—			—			4			4
UAL 6% Senior Convertible Notes		—			—			40			—

UAL’s 6% Senior Notes due 2031 (the “6% Senior Notes”), with a principal amount of $652 million as of June 30, 2012, and the $125 million of UAL’s 8% Contingent Senior Notes (the “8% Notes”) issued by UAL in January 2012, are redeemable with either cash or shares of UAL common stock, or in the case of mandatory redemption, a combination thereof, at UAL’s option. The Company is obligated to issue an additional $62.5 million of the 8% Notes by February 2013, which are also redeemable on the same terms as the 6% Senior Notes and the other 8% Notes. These notes are not included in the diluted earnings (loss) per share calculation because it is UAL’s intent to redeem these notes with cash if UAL were to decide to redeem these notes.

During the second quarter of 2011, UAL repurchased at par value approximately $570 million of the $726 million outstanding principal amount of its 4.5% Senior Limited-Subordination Convertible Notes due 2021 (the “4.5% Notes”) with cash after the 4.5% Notes were put to UAL by the noteholders. For the three and six months ended June 30, 2011, the dilutive effect of the 4.5% Notes was excluded from the diluted earnings per share calculations from the date that notice was given of the Company’s intent to pay the notes put to it in cash up to the June 30, 2011 repurchase date.

19

NOTE 4—INCOME TAXES

Our effective tax rates are lower than the federal statutory rate of 35% primarily because of the impact of changes to existing valuation allowances. We continue to provide a valuation allowance for our deferred tax assets in excess of deferred tax liabilities because we have concluded that it is more likely than not that such deferred tax assets will ultimately not be realized.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including the reversals of deferred tax liabilities) during the periods in which those deferred tax assets will become deductible. The Company’s management assesses available positive and negative evidence regarding the realizability of its deferred tax assets, and records a valuation allowance when it is more likely than not that all or a portion of the deferred tax assets will not be realized. To form a conclusion, management considers positive evidence in the form of reversing temporary differences, projections of future taxable income and tax planning strategies, and negative evidence such as recent history of losses. Although the Company was no longer in a three-year cumulative loss position at the end of 2011, management determined that the size and frequency of financial losses in recent years and the uncertainty associated with projecting future taxable income supported the conclusion that the valuation allowance was still needed on net deferred tax assets. If UAL achieves significant profitability in 2012, then management will evaluate whether its recent history of profitability constitutes sufficient positive evidence to support a reversal of a portion, or all, of the remaining valuation allowance.

During the six months ended June 30, 2012, Continental contributed $75 million to its tax-qualified defined benefit pension plans. Continental contributed an additional $41 million to its tax-qualified defined benefit pension plans in July 2012.

Share-Based Compensation. In February 2012, UAL granted share-based compensation awards pursuant to the United Continental Holdings, Inc. 2008 Incentive Compensation Plan. These share-based compensation awards include approximately 0.5 million shares of restricted stock and 0.6 million restricted stock units (“RSUs”) that vest pro-rata over three years on the anniversary of the grant date. In addition, UAL granted 1.3 million performance-based RSUs which will vest based on UAL’s return on invested capital for the three years ending December 31, 2014. If this performance condition is achieved, cash payments will be made after the end of the performance period based on the 20-day average closing price of UAL common stock immediately prior to the vesting date. The Company accounts for the RSUs as liability awards. The table below presents information related to share-based compensation (in millions):

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2011		2012		2011
Share-based compensation expense (a)	$	11	$	14	$	26	$	27

	June 30, 2012		December 31, 2011
Unrecognized share-based compensation expense	$	47	$	43

(a) Includes $3 million and $7 million of expense recognized in integration-related costs for the three and six months ended June 30, 2012, respectively. Includes $6 million and $9 million of expense recognized in integration-related costs for the three and six months ended June 30, 2011, respectively.

Profit Sharing Plans. In 2012, substantially all employees participate in profit sharing, which pays 15% of total pre-tax earnings, excluding special items and share-based compensation expense, to eligible employees when pre-tax profit, excluding special items, profit sharing expense and share-based compensation program expense, exceeds $10 million. Eligible U.S. co-workers in each participating work group receive a profit sharing payout using a formula based on the ratio of each qualified co-worker’s annual eligible earnings to the eligible earnings of all qualified co-workers in all domestic workgroups. The international profit sharing plan pays eligible non-U.S. co-workers the same percentage of eligible pay that is calculated under the U.S. profit sharing plan. UAL recorded $54 and $90 million of profit sharing and related payroll tax expense in the six months ended June 30, 2012 and 2011, respectively. Profit sharing expense is recorded as a component of salaries and related costs in the consolidated statements of operations.

(a) These derivatives are not designated as hedges. The Convertible Debt Supplemental Derivative Asset is classified in “Other Asset - Other, net”, and the Convertible Debt Conversion Option Liability is classified in “Other liabilities and deferred credits - Other” in Continental’s consolidated balance sheets. The earnings impact is classified in “Nonoperating income (expense) - Miscellaneous, net” in Continental’s statements of consolidated operations.

As of June 30, 2012, Continental’s auction rate securities, which had a par value of $135 million and an amortized cost basis of $112 million, were variable-rate debt instruments with contractual maturities generally greater than ten years and with interest rates that reset every 7, 28 or 35 days, depending on the terms of the particular instrument. These securities are backed by pools of student loans guaranteed by state-designated guaranty agencies and reinsured by the U.S. government. All of the auction rate securities that Continental holds are senior obligations under the applicable indentures authorizing the issuance of the securities.

As of June 30, 2012, United’s EETC securities have an amortized cost basis of $64 million and unrealized losses of $1 million. All changes in the fair value of these investments have been classified within accumulated other comprehensive income.

Continental’s debt-related derivatives presented in the tables above relate to (a) supplemental indenture agreements that provide that Continental’s convertible debt, which was previously convertible into shares of Continental common stock, is convertible into shares of UAL common stock upon the terms and conditions specified in the indentures, and (b) the embedded conversion options in Continental’s convertible debt that are required to be separated and accounted for as though they are free-standing derivatives as a result of the Continental debt becoming convertible into the common stock of a different reporting entity. These derivatives are reported in Continental’s separate financial statements and eliminated in consolidation for UAL.

The table below presents the carrying values and estimated fair values of financial instruments not presented in the tables above as of June 30, 2012 and December 31, 2011 (in millions):

Quantitative Information About Level 3 Fair Value Measurements as of June 30, 2012 ($ in millions)

Item	Fair Value at June 30, 2012			Valuation Technique	Unobservable Input	Range (Weighted Average)
Auction rate securities	$	112		Discounted Cash Flows	Credit risk premium (a) Illiquidity premium (b) Expected repayments (c)	1% 5% Assumed repayment in years 2013 through 2036
EETC	$	63		Discounted Cash Flows	Structure credit risk (d)	7% - 9% (8%)

Convertible debt option liability	$	(147	)	Binomial Lattice Model	Expected volatility (e) Own credit risk (f)	45% - 60% (48%) 7% - 10% (8%)

(a) Represents the credit risk premium component of the discount rate that the Company has determined market participants would use in pricing the investments.

(b) Represents the illiquidity premium component of the discount rate that the Company has determined market participants would use in pricing the investments.

(c) Represents the estimated timing of principal repayments used in the discounted cash flow model.

(d) Represents the credit risk premium of the EETC structure above the risk-free rate that the Company has determined market participants would use in pricing the instruments.

(e) Represents the range in volatility estimates that the Company has determined market participants would use when pricing the instruments.

(f) Represents the range of Company-specific risk adjustments that the Company has determined market participants would use as a model input.

Valuation Processes—Level 3 Measurements—The Company’s internal valuation group is responsible for determining the fair value of financial instruments. Depending on the instrument, the valuation group utilizes discounted cash flow methods or option pricing methods as indicated above. Valuations using discounted cash flow methods are generally conducted by the valuation group. Valuations using option pricing models are generally provided to the Company by third-party valuation experts. Each reporting period, the valuation group reviews the unobservable inputs used by third-party valuation experts for reasonableness utilizing relevant information available to the Company from other published sources. The Company has a formal process to review changes in fair value for satisfactory explanation.

Sensitivity Analysis—Level 3 Measurements—Changes in the unobservable input values would be unlikely to cause material changes in the fair value of the auction rate securities and EETCs.

The significant unobservable inputs used in the fair value measurement of the Continental convertible debt derivative assets and liabilities are the UAL stock expected volatility and the Company’s own credit risk. Significant increases (decreases) in expected volatility would result in a higher (lower) fair value measurement. Significant increases (decreases) in the Company’s own credit risk would result in a lower (higher) fair value measurement. A change in one of the inputs would not necessarily result in a directionally similar change in the other.

25

Fair value of the financial instruments included in the tables above was determined as follows:

Description	Fair Value Methodology
Cash and Cash Equivalents	The carrying amounts approximate fair value because of the short-term maturity of these assets.
Short-term Investments, Investments, and Restricted Cash	Fair value is based on (a) the trading prices of the investment or similar instruments, (b) an income approach, which uses valuation techniques to convert future amounts into a single present amount based on current market expectations about those future amounts when observable trading prices are not available, or (c) internally-developed models of the expected future cash flows related to the securities. These assets have maturities of less than one year except for the EETCs, auction rate securities and corporate debt.
Fuel Derivatives	Derivative contracts are privately negotiated contracts and are not exchange traded. Fair value measurements are estimated with option pricing models that employ observable inputs. Inputs to the valuation models include contractual terms, market prices, yield curves, fuel price curves and measures of volatility, among others.
Foreign Currency Derivatives	Fair value is determined with a formula utilizing observable inputs. Significant inputs to the valuation models include contractual terms, risk-free interest rates and forward exchange rates.
Debt	Fair values were based on either market prices or the discounted amount of future cash flows using our current incremental rate of borrowing for similar liabilities.
Convertible Debt Derivative Asset and Option Liability	The Company used a binomial lattice model to value the conversion options and the supplemental derivative assets. Significant binomial model inputs that are not objectively determinable include volatility and discount rate.

NOTE 7—HEDGING ACTIVITIES

Aircraft Fuel Hedges. The Company has a risk management strategy to hedge a portion of its price risk related to projected aircraft fuel requirements. The Company periodically enters into derivative contracts to mitigate the adverse financial impact of potential increases in the price of fuel. The Company does not enter into derivative instruments for speculative, non-risk management purposes.

Upon proper qualification, the Company accounts for its fuel derivative instruments as cash flow hedges. All derivatives designated as hedges that meet certain requirements are granted special hedge accounting treatment. Generally, utilizing the special hedge accounting, all periodic changes in fair value of the derivatives designated as hedges that are considered to be effective are recorded in accumulated other comprehensive income (loss) (“AOCI”) until the underlying fuel is consumed and recorded in fuel expense. The Company is exposed to the risk that its hedges may not be effective in offsetting changes in the cost of fuel and that its hedges may not continue to qualify for special hedge accounting. Hedge ineffectiveness results when the change in the fair value of the derivative instrument exceeds the change in the value of the Company’s expected future cash outlay to purchase and consume fuel. To the extent that the periodic changes in the fair value of the derivatives are not effective, that ineffectiveness is classified as other nonoperating income (expense).

The Company records each derivative instrument as a derivative asset or liability on a gross basis in its consolidated balance sheets and, accordingly, records any related collateral on a gross basis.

26

As of June 30, 2012, our projected fuel requirements for the remainder of 2012 were hedged as follows:

	Maximum Price					Minimum Price
	% of Expected Consumption			Weighted Average  Price (per gallon)		% of Expected Consumption			Weighted Average  Price (per gallon)
UAL (a)
Heating oil collars		20	%	$	3.41		20	%	$	2.74

Derivative Credit Risk and Fair Value

The Company is exposed to credit losses in the event of nonperformance by counterparties to its derivative instruments. While the Company records derivative instruments on a gross basis, the Company monitors its net derivative position with each counterparty to monitor credit risk. Based on the fair value of our fuel derivative instruments, our counterparties may require us to post collateral when the price of the underlying commodity decreases, and we may require our counterparties to provide us with collateral when the price of the underlying commodity increases. The following table presents information related to the Company’s derivative credit risk as of June 30, 2012 (in millions):

NOTE 8—COMMITMENTS AND CONTINGENCIES

General Guarantees and Indemnifications. In the normal course of business, the Company enters into numerous real estate leasing and aircraft financing arrangements that have various guarantees included in the contracts. These guarantees are primarily in the form of indemnities under which the Company typically indemnifies the lessors and any tax/financing parties against tort liabilities that arise out of the use, occupancy, operation or maintenance of the leased premises or financed aircraft. Currently, the Company believes that any future payments required under these guarantees or indemnities would be immaterial, as most tort liabilities and related indemnities are covered by insurance (subject to deductibles). Additionally, certain leased premises such as fueling stations or storage facilities include indemnities of such parties for any environmental liability that may arise out of or relate to the use of the leased premises.

Legal and Environmental Contingencies. The Company has certain contingencies resulting from litigation and claims incident to the ordinary course of business. Management believes, after considering a number of factors, including (but not limited to) the information currently available, the views of legal counsel, the nature of contingencies to which the Company is subject and prior experience, that the ultimate disposition of these contingencies will not materially affect the Company’s consolidated financial position or results of operations.

The Company records liabilities for legal and environmental claims when a loss is probable and reasonably estimable. These amounts are recorded based on the Company’s assessments of the likelihood of their eventual disposition.

Commitments. On July 12, 2012, UAL entered into a purchase agreement with The Boeing Company (“Boeing”) for a firm narrowbody aircraft order of 100 Boeing 737 MAX 9 aircraft, with options to purchase an additional 100 Boeing 737 MAX 9 aircraft (the “737 MAX 9 Agreement”). Also on July 12, 2012, United entered into a purchase agreement with Boeing for a firm narrowbody aircraft order of 50 Boeing 737-900ER aircraft, with options to purchase an additional 60 Boeing 737-900ER aircraft. The firm order 50 Boeing 737-900ER aircraft and 100 Boeing 737 MAX 9 aircraft are expected to be delivered between 2013 and 2022.

The July 2012 Boeing aircraft order is part of the Company’s flexible fleet strategy, which provides the Company the ability to replace older, less fuel efficient aircraft and to adjust the size of its fleet to respond to market conditions and opportunities. Specifically, the Boeing 737-900ER order discussed above would largely serve as replacement for Boeing 757-200 aircraft that are operated by United whose leases expire over the next five years.

United Aircraft Commitments. As of June 30, 2012 (adjusted to include the order discussed above), United had firm commitments to purchase 100 new aircraft (25 Boeing 787 aircraft, 50 Boeing 737-900ER aircraft and 25 Airbus A350XWB aircraft) scheduled for delivery from 2013 through 2019. United also has options and purchase rights for 152 additional Boeing and Airbus aircraft.

Continental Aircraft Commitments. As of June 30, 2012 (adjusted to include the order discussed above) Continental had firm commitments to purchase 72 new aircraft (47 Boeing 737 aircraft and 25 Boeing 787 aircraft) scheduled for delivery from 2012 through 2016. Continental also has options to purchase 89 Boeing aircraft. From July 1, 2012 through December 31, 2012, Continental expects to take delivery of nine Boeing 737-900ER aircraft and five Boeing 787-8 aircraft.

28

United has secured considerable backstop financing commitments from its widebody aircraft and engine manufacturers, subject to certain customary conditions. In addition, Continental has arranged for financing of five Boeing 737-900ER aircraft and four Boeing 787-8 aircraft scheduled for delivery from July 2012 through December 2012. See Note 9 of this report for additional information. However, UAL and United do not have backstop financing or any other financing currently in place for their firm narrowbody aircraft orders with Boeing, and Continental does not have backstop financing or any other financing currently in place for its other Boeing aircraft on order. Financing will be necessary to satisfy the Company’s capital commitments for its firm order aircraft and other related capital expenditures. The Company can provide no assurance that any financing not already in place for aircraft and spare engine deliveries will be available to the Company on acceptable terms when necessary or at all.

The table below summarizes the capital commitments of the Company, United and Continental as of June 30, 2012, which primarily relate to the acquisition of aircraft and related spare engines, aircraft improvements and acquisition of information technology services and assets. The table below is adjusted to include the impact of the July 2012 Boeing 737-900ER and 737 MAX 9 aircraft orders discussed above. As UAL has the right, and intends in the future, to assign its interest under the 737 MAX 9 Agreement with respect to one or more of the Boeing 737 MAX 9 aircraft to either United or Continental, but has not determined the actual assignment of the Boeing 737 MAX 9 between United and Continental, the table below assumes that 50% of the Boeing 737 MAX 9 order is assigned to United and 50% of the Boeing 737 MAX 9 order is assigned to Continental. The table below is also adjusted to include the impact of the resolution between the Company and Boeing in July 2012 relating to compensation in connection with certain Boeing 787 aircraft delivery delays, which contemplates certain adjustments to Continental’s and United’s Boeing 787 purchase agreements.

	In billions

After 2016		9.7		7.2		2.5
	$	18.5	$	11.3	$	7.2

Any incremental firm aircraft orders, including through the exercise of purchase options, will increase the total future capital commitments of the Company, United and/or Continental.

UAL and Continental have concluded their discussions with Boeing regarding delays in delivery of certain Boeing 787 aircraft, and have reached a resolution with Boeing regarding compensation to be received in connection with those delays.

Credit Card Processing Agreements. United and Continental have agreements with financial institutions that process customer credit card transactions for the sale of air travel and other services. Under certain of United’s and Continental’s credit card processing agreements, the financial institutions either require, or under certain circumstances have the right to require, that United and Continental maintain a reserve equal to a portion of advance ticket sales that have been processed by that financial institution, but for which United and Continental have not yet provided the air transportation.

As of June 30, 2012, $25 million was provided by the Company as a cash reserve for its credit card processing agreement with JPMorgan Chase Bank, N.A. and Paymentech, LLC. Our credit card processing agreement with JPMorgan Chase Bank, N.A. and Paymentech, LLC to process MasterCard/Visa transactions and our credit card processing agreement with American Express allow the applicable financial institution to require additional cash or other collateral reserves to be established or additional withholding of payments related to receivables collected if the Company does not maintain certain minimum levels of unrestricted cash, cash equivalents and short term investments. The Company’s current level of unrestricted cash, cash equivalents and short term investments is substantially in excess of these minimum levels. The amount of required cash or other collateral reserves or withheld payments would be no more than the liability of the credit card processor for tickets purchased with the applicable credit cards for travel that had not occurred. In conjunction with the single passenger service system conversion in March 2012, all tickets sold since that date have been on United ticket stock. As a result, the advance ticket sales by Continental have diminished and are expected to be zero by March 2013.

29

Guarantees and Off-Balance Sheet Financing.

Guarantees. United and Continental are the guarantors of approximately $270 million and $1.7 billion, respectively, in aggregate principal amount of tax-exempt special facilities revenue bonds and interest thereon. These bonds, issued by various airport municipalities, are payable solely from rentals paid under long-term agreements with the respective governing bodies. The leasing arrangements associated with $1.8 billion ($270 million for United and $1.5 billion for Continental) of these obligations are accounted for as operating leases with the associated expense recorded on a straight-line basis resulting in ratable accrual of the lease obligation over the expected lease term. The leasing arrangements associated with $190 million (for Continental only) of these obligations are accounted for as capital leases. These bonds are due between 2015 and 2033.

In the Company’s financing transactions that include loans, the Company typically agrees to reimburse lenders for any reduced returns with respect to the loans due to any change in capital requirements and, in the case of loans in which the interest rate is based on the London Interbank Offered Rate (“LIBOR”), for certain other increased costs that the lenders incur in carrying these loans as a result of any change in law, subject in most cases to obligations of the lenders to take certain limited steps to mitigate the requirement for, or the amount of, such increased costs. At June 30, 2012, UAL had $2.5 billion of floating rate debt (consisting of United’s $2.0 billion and Continental’s $498 million of debt) and $376 million of fixed rate debt (consisting of United’s $195 million and Continental’s $181 million of debt), with remaining terms of up to ten years, that are subject to these increased cost provisions. In several financing transactions involving loans or leases from non-U.S. entities, with remaining terms of up to ten years and an aggregate balance of $2.8 billion (consisting of United’s $2.2 billion and Continental’s $595 million balance), the Company bears the risk of any change in tax laws that would subject loan or lease payments thereunder to non-U.S. entities to withholding taxes, subject to customary exclusions.

Houston Bush Terminal B Redevelopment Project. In May 2011, UAL, in partnership with the Houston Airport System, announced that it would begin construction of the first phase of a potential three-phase $1 billion terminal improvement project for Terminal B at George Bush Intercontinental Airport (“Houston Bush”) by the end of 2011. In November 2011, the City of Houston issued approximately $113 million of special facilities revenue bonds to finance the construction of a new south concourse at Houston Bush dedicated to the Company’s regional jet operations. The bonds are guaranteed by Continental and are payable from certain rentals paid by Continental under a special facilities lease agreement with the City of Houston. Continental’s initial commitment is to construct the first phase of the originally anticipated three-phase project. Continental’s cost of construction of phase one of the project is currently estimated to be approximately $100 million and is funded by special facilities revenue bonds. Construction of the remaining phases of the project, if any, will be based on demand over the next seven to 10 years, with phase one currently expected to be completed in late 2013.

Based on a qualitative assessment of the Houston Bush Terminal B Redevelopment Project, due to the fact that Continental is guaranteeing the special facilities revenue bonds and the requirement that Continental fund cost overruns with no stated limits, Continental is considered the owner of the property during the construction period for accounting purposes. As a result, the construction project is being treated as a financing transaction such that the property and related financing will be included on UAL’s consolidated balance sheet as an asset under operating property and equipment and as a construction obligation under other long-term liabilities.

Credit Facilities. As of June 30, 2012 the Company had its entire commitment capacity of $500 million available under the Credit and Guaranty Agreement, dated as of December 22, 2011 (the “Revolving Credit Facility”) with a syndicate of banks led by Citibank N.A., as administrative agent. The Revolving Credit Facility has an expiration date of January 30, 2015.

Labor Negotiations. As of June 30, 2012, UAL and its subsidiaries had approximately 88,000 active employees, of whom approximately 80% are represented by various U.S. labor organizations. On February 27, 2012, the pilots at both United and Continental agreed to an extension of their protocol for joint negotiations and continue to engage in joint bargaining with the Company. On February 28, 2012, the flight attendants at United ratified a new collective bargaining agreement and, on July 13, 2012, the flight attendants at Continental ratified a new collective bargaining agreement. On July 17, 2012, the Company reached a tentative agreement with its Continental Micronesia flight attendants, subject to ratification in the third quarter of 2012. Joint negotiations will begin shortly for a joint collective bargaining agreement covering the Company’s flight attendant work groups.

On March 7, 2012, the passenger service employees at both United and Continental voted to be represented by the International Association of Machinists and Aerospace Workers, AFL-CIO and negotiations are underway for a joint collective bargaining agreement for this employee group. The Company reached a tentative agreement with the United ground instructors, which the United ground instructors ratified on June 8, 2012. We are continuing our negotiations for joint collective bargaining agreements with other work groups, including technicians, dispatchers, fleet service employees, storekeepers and various smaller groups.

NOTE 9—DEBT

As of June 30, 2012, a substantial portion of our assets are pledged as collateral for our debt. These assets principally consist of aircraft and the related spare parts and engines, route authorities and loyalty program intangible assets. As of June 30, 2012, UAL, United and Continental were in compliance with their respective debt covenants.

Continental EETCs. In March 2012, Continental created two pass-through trusts, one of which issued $753 million aggregate principal amount of Class A pass-through certificates with a stated interest rate of 4.15% and the other of which issued $139 million aggregate principal amount of Class B pass-through certificates with a stated interest rate of 6.25%. The proceeds of the issuance of the Class A and Class B pass-through certificates, which amounted to $892 million, have been and will be used to purchase equipment notes issued by Continental. Of the $892 million in proceeds raised by the pass-through trusts, Continental received $392 million as of June 30, 2012, in exchange for Continental’s issuance of an equivalent principal amount of equipment notes, which has been recorded as debt. The remaining amount is expected to be received during the last six months of this year as aircraft are delivered to Continental and Continental issues equipment notes to the trusts. Continental records the debt obligation upon issuance of the equipment notes rather than upon the initial issuance of the pass-through certificates. The proceeds have been and are expected to be used to fund the acquisition of new aircraft, and in the case of currently owned aircraft, for general corporate purposes.

The Company evaluated whether the pass-through trusts formed are variable interest entities (“VIEs”) required to be consolidated by the Company under applicable accounting guidance, and determined that the pass-through trusts are VIEs. The Company determined that it does not have a variable interest in the pass-through trusts. The Company does not invest in or obtain a financial interest in the pass-through trusts. Rather, Continental has an obligation to make interest and principal payments on its equipment notes held by the pass-through trusts. The Company did not intend to have any voting or non-voting equity interest in the pass-through trusts or to absorb variability from the pass-through trusts. Based on this analysis, the Company determined that it is not required to consolidate the pass-through trusts.

8% Contingent Senior Notes. UAL is obligated under an indenture to issue to the Pension Benefit Guaranty Corporation (“PBGC”) up to $500 million aggregate principal amount of 8% Notes in up to eight equal tranches of $62.5 million if certain financial triggering events occur (with each tranche issued no later than 45 days following the end of any applicable fiscal year).

During 2011, a financial triggering event under the 8% Notes indenture occurred at both June 30, 2011 and December 31, 2011 and, as a result, UAL issued two tranches of $62.5 million each of the 8% Notes in January 2012, which were recorded during 2011 at their fair value of $88 million as a component of integration costs. In addition, at June 30, 2012, a financial triggering event under the 8% Notes indenture occurred and, as a result, UAL is obligated to issue an additional tranche of $62.5 million of the 8% Notes by February 2013. UAL recorded a liability for the fair value of the obligation of $48 million during the second quarter of 2012.

NOTE 10—SPECIAL ITEMS

Special Revenue. During the second quarter of 2011, the Company modified the previously existing United and Continental co-branded credit card agreements with Chase Bank USA, N.A. This modification resulted in the following one-time adjustment to decrease frequent flyer deferred revenue and increase special revenue in accordance with ASU 2009-13 for the three and six months ended June 30, 2011 as follows (in millions):

	UAL		United		Continental
Special revenue item	$	107	$	88	$	19

31

Special Charges. For the three and six months ended June 30, special charges consisted of the following (in millions):

	Three Months Ended June 30,								Six Months Ended June 30,
2012	UAL			United		Continental			UAL			United			Continental
Integration-related costs	$	137		$	98	$	39		$	271		$	169		$	102

Total	$	146		$	90	$	56		$	223		$	164		$	59

Integration-related costs include compensation costs related to systems integration and training, costs to repaint aircraft and other branding activities, costs to write-off or accelerate depreciation on systems and facilities that are no longer used or planned to be used for significantly shorter periods, relocation costs for employees and severance primarily associated with administrative headcount reductions. In addition, financial triggering events under the 8% Notes indenture occurred at both June 30, 2012 and 2011 and as a result, UAL became obligated to issue one tranche of $62.5 million in aggregate principal amount of the 8% Notes with respect to each of these financial triggering events. The obligation to issue these tranches was recorded at their fair values of $48 million and $49 million as of June 30, 2012 and 2011, respectively. Both obligations described above were recorded as integration-related costs because the financial results of UAL, excluding Continental’s results, would not have resulted in triggering events under the 8% Notes indenture.

During the three and six months ended June 30, 2012, the Company recorded $76 million and $125 million of severance and benefits associated with three voluntary employee programs, respectively. During the first quarter of 2012, approximately 400 mechanics offered to retire early in exchange for a cash severance payment that was based on the number of years of service each employee had accumulated. The Company also offered a voluntary leave of absence program that approximately 1,800 flight attendants accepted, which allows for continued medical coverage during the leave of absence period. During the second quarter of 2012, as part of the recently amended collective bargaining agreement with the Association of Flight Attendants, the Company offered a voluntary program for flight attendants at United to retire early in exchange for a cash severance payment. The payments are dependent on the number of years of service each employee has accumulated. Approximately 1,300 flight attendants accepted this program and the Company estimates the amount for this voluntary program to be approximately $76 million.

In addition, the Company sold nine aircraft during the first six months of 2012, of which three were sold during the second quarter. The Company also made adjustments to certain legal reserves.

The Company expects to consolidate its headquarters facilities by the middle of 2013. During the consolidation process, the Company expects to record special charges for accelerated depreciation and lease expense on unused facilities associated with the facility that it vacates. The Company estimates that these charges will be approximately $60 million to $80 million in total, which are expected to be recorded in late 2012 through 2013.

Accruals

The accrual for severance and medical costs was $153 million, $137 million and $16 million related to UAL, United and Continental, respectively, as of June 30, 2012. In addition, the accrual balance of future lease payments on permanently grounded aircraft was $8 million for both UAL and United as of June 30, 2012.

The severance-related accrual as of June 30, 2012, which primarily relates to the integration of United and Continental, is expected to be paid through 2014. Lease payments for grounded aircraft are expected to continue through 2013.

32

At June 30, 2011, the accrual balance for severance and medical costs was $70 million, $40 million and $30 million, related to UAL, United and Continental, respectively. In addition, the accrual balance of future lease payments on permanently grounded aircraft was $34 million for both UAL and United as of June 30, 2011.

NOTE 11—RELATED PARTY TRANSACTIONS

Intercompany transactions—United and Continental

United and Continental perform services for one another including various aircraft maintenance services and aircraft ground handling at certain airports, and they utilize one management team to oversee the sales and administrative functions of both airlines. For services provided, Continental paid United $268 million and United paid Continental $230 million during the quarter ended June 30, 2012. These payments do not include interline billings, which are common among airlines for transportation-related services. Most of these transactions are routinely settled through the clearing house, which is customarily used in the monthly settlement of such items. Transactions not settled through the clearing house are typically settled in cash on a quarterly basis. As of June 30, 2012, Continental had a net current payable of $2.2 billion to United primarily related to the transfer of the current portion of the frequent flyer liability and the cash transfer from United in conjunction with the conversion to the new passenger service system, as described below. In addition, Continental had a $0.7 billion noncurrent payable to United associated with the transfer of the long-term portion of the frequent flyer liability.

Frequent flyer program transition

In the first quarter of 2012, the Company moved to a single loyalty program. Continental’s loyalty program formally ended in the first quarter of 2012, at which point United automatically enrolled Continental OnePass program members in the MileagePlus program and deposited into those MileagePlus accounts award miles equal to these members’ OnePass award miles balance. In March 2012, the related frequent flyer deferred revenue and advance purchase of miles liabilities for the OnePass program was transferred to United with a corresponding liability recorded by Continental payable to United for assuming the frequent flyer obligations. No gain or loss was incurred from the transaction as the liabilities were transferred at their respective net book value. The obligation associated with this transfer will be settled by Continental through future redemptions by MileagePlus members on Continental operated flights.

Passenger service system and ticket stock integration

In March 2012, Continental and United converted to a single passenger service system, allowing the Company to operate using a single reservations system, carrier code, flight schedule, website and departure control system. In conjunction with the conversion to a single passenger service system, all tickets are now sold by United. As a result, the air traffic liability of Continental is diminishing as tickets previously sold by Continental are used or refunded and United’s advanced ticket sales liability and associated cash receipts from the ticket sales will increase accordingly. Subsequent to the system conversion, United transferred cash to Continental each month, such transfers being netted against amounts owed to Continental for segments flown by Continental on United ticket stock. Revenue will continue to be recorded by the carrier that is operating the flight.

Revenue and expense allocation

In November 2011, the Company received a single operating certificate from the Federal Aviation Administration. The Company plans to merge Continental and United into one legal entity. Once this legal merger occurs, the financial statements of United and Continental will be combined at their historical cost for all periods presented beginning on October 1, 2010, the date on which Continental became a wholly-owned subsidiary of UAL, and there will no longer be a requirement to separately report the historical financial statements of Continental.

Until Continental and United are merged into one legal entity, revenue and expenses will continue to be recorded by each entity based on either specific identification of the related transaction, where applicable, or appropriate allocations based on metrics that are systematic and rational. Certain revenues and expenses that were previously recorded based on a specific identification were allocated in March 2012 in connection with the conversion to a single passenger service system. We believe the allocated amounts will generally be comparable to historical amounts. Each airline will continue to record actual expenses for aircraft that are owned or leased and passenger revenue will be determined on an actual basis for the carrier operating the flight. The table below illustrates a summary of the primary allocation metrics to be used:

33

Account	Allocation metric between subsidiaries
Operating revenue:
Passenger	Actual ticket revenue based on specifically identified flights operated by each carrier. Frequent flyer component of passenger revenue based on historic revenue passenger miles (“RPMs”) split between carriers. Regional revenue, based on the carrier that contracted with the regional carrier
Cargo	Actual by operating carrier
Other operating	Passenger related based on passenger revenue and other based on passengers enplaned or other similar criteria
Operating expense:
Aircraft fuel	Actual by operating carrier
Salaries and related costs	Actual for operational workgroups and allocation based on historical RPMs for administrative personnel. Profit sharing expense is allocated based on the proportional profit of each operating entity
Regional capacity purchase	Actual based on specific identification of the carrier that contracted with regional carrier for flying
Landing fees and other rent	Allocation based on passengers enplaned
Aircraft maintenance materials and outside repairs	Actual based on the specific identification of each carrier’s aircraft
Depreciation and amortization	Specific identification of carriers’ operational assets (i.e. flight equipment) and intangible assets and allocation based on historical RPMs for other assets
Distribution expenses	Allocation based on passenger revenue
Aircraft rent	Actual based on specific identification of each carrier’s aircraft
Special charges	Specific identification
Other operating expenses	Specific identification where applicable and allocation based on historical RPMs for other

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Overview

United Continental Holdings, Inc. (together with its consolidated subsidiaries, “UAL”) is a holding company and its principal, wholly-owned subsidiaries are United Air Lines, Inc. (together with its consolidated subsidiaries, “United”) and Continental Airlines, Inc. (together with its consolidated subsidiaries, “Continental”). All significant intercompany transactions are eliminated.

This Quarterly Report on Form 10-Q is a combined report of UAL, United and Continental. We sometimes use the words “we,” “our,” “us,” and the “Company” for disclosures that relate to all of UAL, United and Continental. As UAL consolidates United and Continental for financial statement purposes, disclosures that relate to United and Continental activities also apply to UAL. When appropriate, UAL, United and Continental are named specifically for their related activities and disclosures.

The Company transports people and cargo through its mainline operations, which utilize jet aircraft with at least 100 seats, and regional operations, which utilize smaller aircraft that are operated under contract by United Express carriers. The Company serves virtually every major market around the world, either directly or through participation in Star Alliance^®, the world’s largest airline alliance. Based on flight schedules as of July 1, 2012, the Company offers approximately 5,600 daily departures to 375 destinations.

Second Quarter Financial Highlights

• UAL’s second quarter 2012 net income was $545 million, or $1.41 diluted earnings per share, excluding $206 million of special charges, net of tax. On a GAAP basis, UAL’s second quarter 2012 net income was $339 million, or $0.89 diluted earnings per share.

• UAL’s passenger revenue increased 2.3% during the second quarter of 2012 as compared to the second quarter of 2011.

• UAL’s second quarter 2012 fuel cost increased 5.6% year-over-year.

• UAL’s unrestricted cash, cash equivalents and short-term investments totaled $7.7 billion at June 30, 2012.

Second Quarter Operational Highlights

• UAL’s traffic increased and capacity decreased 0.5% and 0.6%, respectively, during the second quarter of 2012 as compared to the second quarter of 2011. The Company’s load factor for the second quarter of 2012 was 84.3%.

• For the quarter ended June 30, 2012, the Company recorded a U.S. Department of Transportation on-time arrival rate of 76.4% and a system completion factor of 99.1%.

• The Company took delivery of six new Boeing 737-900ER aircraft during the second quarter of 2012.

Outlook

In order to generate sustained profitability over the business cycle, the Company manages its capacity to balance with expected demand for travel. The Company plans to reduce 2012 consolidated capacity by reducing flight frequencies, indefinitely postponing the start of flights to certain markets and exiting less profitable markets. As compared to 2011 capacity, the Company expects full-year 2012 consolidated capacity to be down 0.5% to 1.5% year-over-year, with full-year 2012 domestic capacity to be down 1.5% to 2.5% and full-year 2012 international capacity to be down 0.3% to up 0.7%. The Company is also analyzing the removal of certain less fuel-efficient aircraft from its fleet and other cost-saving measures.

Integration

The Company has made significant progress toward integrating products, services and policies. Following the conversion of its passenger service system in the first quarter of 2012, the Company now has a single loyalty program, MileagePlus, and a single website, united.com. Continental’s OnePass loyalty program formally ended in the first quarter of 2012, at which point United automatically enrolled OnePass members in the MileagePlus program and deposited into those MileagePlus accounts award miles equal to their OnePass award miles balance.

In March 2012, UAL converted to a single passenger service system allowing the Company to operate using a single reservations system, carrier code, flight schedule, website and departure control system.

RESULTS OF OPERATIONS

The following discussion provides an analysis of UAL’s results of operations and reasons for material changes therein for the three and six months ended June 30, 2012 as compared to the corresponding periods in 2011.

Second Quarter 2012 Compared to Second Quarter 2011

UAL recorded net income of $339 million in the second quarter of 2012 as compared to net income of $538 million in the second quarter of 2011. Excluding special items, UAL had net income of $545 million in the second quarter of 2012 as compared to net income of $577 million in the second quarter of 2011. See “Reconciliation of GAAP to non-GAAP Financial Measures” at the end of this item for additional information related to non-GAAP financial measures. We consider a key measure of our performance to be operating income, which was $575 million for the second quarter of 2012, as compared to $808 million for the second quarter of 2011. Significant components of our operating results for the three months ended June 30, are as follows (in millions, except percentage changes):

Passenger load factor (points)		(0.2	)		1.2			1.1			3.1			0.6			2.6			0.9

Consolidated passenger revenue in the second quarter of 2012 increased 2.3% as compared to the year-ago period primarily due to increased pricing as consolidated average fare per passenger and yield increased by 2.1% and 1.8%, respectively. The average fare per passenger increased in the 2012 period as compared to the 2011 period due to a number of fare increases implemented in response to fuel price volatility. Passenger revenue results for the Pacific region for the second quarter of 2012 include insurance proceeds from a business interruption claim from the 2011 Japan earthquake and tsunami. This increased year-over-year consolidated PRASM by approximately 0.3%.

Cargo revenue decreased $51 million, or 16.1%, in the second quarter of 2012 as compared to the year-ago period due to lower volumes and yields on freight and mail, primarily in the Atlantic and Pacific regions.

Other operating revenue increased $90 million, or 11.0%, in the second quarter of 2012 as compared to the year-ago period, primarily due to the application of Accounting Standards Update 2009-13, Multiple-Deliverable Revenue Arrangements-a consensus of the Financial Accounting Standards Board Emerging Issues Task Force (“ASU 2009-13”) upon execution of its co-branded credit card agreement with Chase Bank USA, N.A. at the end of the second quarter 2011, which resulted in a decrease in the deferral of revenue related to miles. See Note 1 to the financial statements included in Part I, Item I of this report for additional information.

Operating Expenses

The table below includes data related to UAL’s operating expenses for the three months ended June 30 (in millions, except for percentage changes):

	2012		2011		Increase (Decrease)			% Change
Aircraft fuel	$	3,408	$	3,227	$	181			5.6
Salaries and related costs		2,024		1,916		108			5.6
Regional capacity purchase		643		615		28			4.6
Landing fees and other rent		503		502		1			0.2
Aircraft maintenance materials and outside repairs		432		444		(12	)		(2.7	)
Depreciation and amortization		378		385		(7	)		(1.8	)
Distribution expenses		345		375		(30	)		(8.0	)
Aircraft rent		251		252		(1	)		(0.4	)
Special charges		206		146		60			NM
Other operating expenses		1,174		1,139		35			3.1
	$	9,364	$	9,001	$	363			4.0

Aircraft fuel expense increased $181 million, or 5.6%, year-over-year due primarily to fuel hedge losses in the current quarter versus gains in the second quarter of 2011. The table below presents the significant changes in aircraft fuel cost per gallon in the three month period ended June 30, 2012 as compared to the year-ago period.

	(In millions)								Average price per gallon
	2012			2011		% Change			2012			2011		% Change
Aircraft fuel expense	$	3,408		$	3,227		5.6		$	3.29		$	3.09		6.5
Fuel hedge gains (losses)		(38	)		278		NM			(0.03	)		0.27		NM
Total fuel purchase cost excluding fuel hedge impacts	$	3,370		$	3,505		(3.9	)	$	3.26		$	3.36		(3.0	)
Total fuel consumption (gallons)		1,035			1,043		(0.8	)

Salaries and related costs increased $108 million, or 5.6%, in the second quarter of 2012 as compared to the year-ago period due to several factors including a 4.2% increase in the number of average full-time employees, higher pay rates primarily driven by new collective bargaining agreements, and overtime for airport and call center employees related to our conversion to a single passenger service system.

Regional capacity purchase increased $28 million, or 4.6%, in the second quarter of 2012 as compared to the year-ago period primarily due to contractual amendments with one of our regional carrier partners to shift the arrangement from a prorate agreement to a capacity purchase agreement and also due to an increase in the contractual rates with such regional carrier partner.

Distribution expenses decreased $30 million, or 8.0%, in the second quarter of 2012 as compared to the year-ago period due to reduced fees with our online ticket agents, lower credit card discount fees driven by legislation reducing costs on debit card sales and lower rates on global distribution systems fees paid in 2012 as compared to 2011.

Other operating expenses increased $35 million, or 3.1%, in the second quarter of 2012 as compared to the year-ago period primarily due to additional trip interruption costs, personnel-related expenses, and higher advertising expenses.

Miscellaneous, net		(38	)		(29	)		9			31.0
Total	$	(235	)	$	(266	)	$	(31	)		(11.7	)

Interest expense decreased $37 million, or 14.8%, in the second quarter of 2012 compared to the year-ago period primarily due to a decrease in debt outstanding during the second quarter of 2012 as compared to debt outstanding during the year-ago period.

During the second quarter of 2012, miscellaneous, net included a fuel hedge ineffectiveness loss of $29 million primarily resulting from a decrease in fuel hedge values in excess of the decrease in aircraft fuel prices during the quarter.

Income Taxes. Our effective tax rates are lower than the federal statutory rate of 35% primarily because of the impact of changes to existing valuation allowances. We continue to provide a valuation allowance for our deferred tax assets in excess of deferred tax liabilities because management has concluded that it is more likely than not that such deferred tax assets will ultimately not be realized.

First Six Months 2012 Compared to First Six Months 2011

UAL recorded a net loss of $109 million in the first six months of 2012 as compared to net income of $325 million in the first six months of 2011. Excluding special items, UAL had net income of $259 million in the first six months of 2012 as compared to net income of $441 million in the first six months of 2011. See “Reconciliation of GAAP to non-GAAP Financial Measures” at the end of this item for additional information related to non-GAAP financial measures. We consider a key measure of our performance to be operating income, which was $304 million for the first six months of 2012, as compared to $842 million for the first six months of 2011. Significant components of our operating results for the first six months of 2012 are as follows (in millions, except percentage changes):

Consolidated passenger revenue in the first six months of 2012 increased 3.8% as compared to the year-ago period primarily due to increased pricing as consolidated average fare per passenger and yield increased by 3.7% and 3.4%, respectively. The average fare per passenger increased in the 2012 period as compared to the 2011 period due to a number of fare increases implemented in response to fuel price volatility. Passenger revenue increased in 2011 as a result of certain accounting changes. In conjunction with these changes, the Company recorded a special adjustment in 2011 to decrease frequent flyer deferred revenue and increase revenue by $107 million in connection with a modification to its co-branded credit card agreement with Chase Bank USA, N.A.

Cargo revenue decreased $70 million, or 11.7%, in the first six months of 2012 as compared to the year-ago period due to lower volumes and yields on freight and mail primarily in the Atlantic and Pacific regions.

Other operating revenue increased $118 million, or 7.3%, in the first six months of 2012 as compared to the year-ago period primarily due to the application of ASU 2009-13 upon execution of its co-branded credit card agreement with Chase Bank USA, N.A. at the end of the second quarter 2011, which resulted in a decrease in the deferral of revenue related to miles. See Note 1 to the financial statements included in Part I, Item I of this report for additional information.

Operating Expenses

The table below includes data related to UAL’s operating expenses for the six months ended June 30 (in millions, except for percentage changes):

	2012		2011		Increase (Decrease)			% Change
Aircraft fuel	$	6,637	$	5,899	$	738			12.5

	$	18,237	$	17,169	$	1,068			6.2

Aircraft fuel expense increased $738 million, or 12.5%, year-over-year due to fuel hedge losses in the first six months of 2012 versus gains in the first six months of 2011. The table below presents the significant changes in aircraft fuel cost per gallon in the six months ended June 30, 2012 as compared to the year-ago period.

	(In millions)							Average price per gallon
	2012			2011		% Change		2012			2011		% Change
Aircraft fuel expense	$	6,637		$	5,899		12.5	$	3.32		$	2.95		12.5
Fuel hedge gains (losses)		(69	)		432		NM		(0.04	)		0.21		NM
Total fuel purchase cost excluding fuel hedge impacts	$	6,568		$	6,331		3.7	$	3.28		$	3.16		3.8
Total fuel consumption (gallons)		2,002			2,003		—

Salaries and related costs increased $199 million, or 5.3%, in the first six months of 2012 as compared to the year-ago period due to several factors including a 2.9% increase in the number of average full-time employees, higher pay rates primarily driven by new collective bargaining agreements, and additional overtime for airport and call center employees related to our conversion to a single passenger service system.

Regional capacity purchase increased $71 million, or 6.0%, in the first six months of 2012 as compared to the year-ago period primarily due to contractual amendments with one of our regional carrier partners to shift the arrangement from a prorate agreement to a capacity purchase agreement and also due to an increase in the contractual rates with such regional carrier partner.

41

Aircraft maintenance materials and outside repairs decreased $44 million, or 5.0%, in the first six months of 2012 as compared to the year-ago period primarily due to lower rates on a new engine maintenance contract as well as fewer airframe maintenance visits in the first half of 2012 as compared to the first half of 2011.

Distribution expenses decreased $43 million, or 5.9%, in the first six months of 2012 as compared to the year-ago period due to reduced fees with our online ticket agents, lower credit card discount fees driven by legislation reducing costs on debit card sales and lower rates on global distribution systems fees paid in 2012 as compared to 2011.

Other operating expenses increased $21 million, or 0.9%, in the second quarter of 2012 as compared to the year-ago period primarily due to increased personnel-related expenses, in-flight supplies, and higher advertising expenses.

Details of UAL’s special charges include the following for the six months ended June 30 (in millions):

	2012			2011
Integration-related costs	$	271		$	224

Special charges	$	370		$	223

See Note 10 to the financial statements included in Part I, Item I of this report.

Nonoperating Income (Expense). The following table illustrates the year-over-year dollar and percentage changes in UAL’s nonoperating income (expense) for the first six months June 30 (in millions, except for percentage changes):

	2012			2011			Increase (Decrease)			% Change
Interest expense	$	(429	)	$	(504	)	$	(75	)		(14.9	)
Interest capitalized		17			14			3			21.4
Interest income		12			9			3			33.3
Miscellaneous, net		(11	)		(30	)		(19	)		(63.3	)
Total	$	(411	)	$	(511	)	$	(100	)		(19.6	)

Interest expense decreased $75 million, or 14.9%, in the first six months of 2012 compared to the year-ago period primarily due to a decrease in debt outstanding during the first six months of 2012 as compared to debt outstanding during the year-ago period.

During the first six months of 2012, miscellaneous, net included a fuel hedge ineffectiveness loss of $4 million primarily resulting from a decrease in fuel hedge ineffectiveness.

Income Taxes. Our effective tax rates are lower than the federal statutory rate of 35% primarily because of the impact of changes to existing valuation allowances. We continue to provide a valuation allowance for our deferred tax assets in excess of deferred tax liabilities because management has concluded that it is more likely than not that such deferred tax assets will ultimately not be realized.

LIQUIDITY AND CAPITAL RESOURCES

Current Liquidity

As of June 30, 2012, UAL had $7.7 billion in unrestricted cash, cash equivalents and short-term investments, as compared to $7.8 billion at December 31, 2011. At June 30, 2012, UAL also had $586 million of restricted cash and cash equivalents, which is primarily collateral for performance bonds, letters of credit, estimated future workers’ compensation claims and credit card processing agreements. As of June 30, 2012, the Company had its entire commitment capacity of $500 million under the Revolving Credit Facility available for letters of credit or borrowings.

42

As is the case with many of our principal competitors, we have a high proportion of debt compared to capital. We have a significant amount of fixed obligations, including debt, aircraft leases and financings, leases of airport property and other facilities, and pension funding obligations. At June 30, 2012, UAL had approximately $12.4 billion of debt and capital lease obligations, including $1.5 billion that will become due in the next 12 months. In addition, we have substantial non-cancelable commitments for capital expenditures, including the acquisition of new aircraft and related spare engines.

The Company will continue to evaluate opportunities to repurchase its debt in open market transactions to reduce its indebtedness and the amount of interest paid on its indebtedness.

On July 12, 2012, UAL entered into a purchase agreement with The Boeing Company (“Boeing”) for a firm narrowbody aircraft order of 100 Boeing 737 MAX 9 aircraft, with options to purchase an additional 100 Boeing 737 MAX 9 aircraft. Also on July 12, 2012, United entered into a purchase agreement with Boeing for a firm narrowbody aircraft order of 50 Boeing 737-900ER aircraft, with options to purchase an additional 60 Boeing 737-900ER aircraft. The firm order 50 Boeing 737-900ER aircraft and 100 Boeing 737 MAX 9 aircraft are expected to be delivered between 2013 and 2022.

The July 2012 Boeing aircraft order is part of the Company’s flexible fleet strategy, which provides the Company the ability to replace older, less fuel efficient aircraft and to adjust the size of its fleet to respond to market conditions and opportunities. Specifically, the Boeing 737-900ER order discussed above would largely serve as replacement for Boeing 757-200 aircraft that are operated by United whose leases expire over the next five years.

As of June 30, 2012 (adjusted to include the order discussed above), United had firm commitments to purchase 100 new aircraft (25 Boeing 787 aircraft, 50 Boeing 737-900ER aircraft and 25 Airbus A350XWB aircraft) scheduled for delivery from 2013 through 2019. United also has options and purchase rights for 152 additional Boeing and Airbus aircraft.

As of June 30, 2012 (adjusted to include the order discussed above) Continental had firm commitments to purchase 72 new aircraft (47 Boeing 737 aircraft and 25 Boeing 787 aircraft) scheduled for delivery from 2012 through 2016. Continental also has options to purchase 89 Boeing aircraft. From July 1, 2012 through December 31, 2012, Continental expects to take delivery of nine Boeing 737-900ER aircraft and five Boeing 787-8 aircraft.

United has secured considerable backstop financing commitments from its widebody aircraft and engine manufacturers, subject to certain customary conditions. In addition, Continental has arranged for financing of five Boeing 737-900ER aircraft and four Boeing 787-8 aircraft scheduled for delivery from July 2012 through December 2012. See Note 9 to the financial statements contained in Part 1, Item 1 of this report for additional information. However, UAL and United do not have backstop financing or any other financing currently in place for their firm narrowbody aircraft orders with Boeing, and Continental does not have backstop financing or any other financing currently in place for its other Boeing aircraft on order. Financing will be necessary to satisfy the Company’s capital commitments for its firm order aircraft and other related capital expenditures. The Company can provide no assurance that any financing not already in place for aircraft and spare engine deliveries will be available to the Company on acceptable terms when necessary or at all.

As of June 30, 2012, adjusted to include the impact of the July 2012 Boeing aircraft order and the impact of the resolution between the Company and Boeing relating to compensation in connection with certain Boeing 787 delivery delays, the Company has total capital commitments primarily related to aircraft and related spare engines, aircraft improvements and acquisition of information technology services and assets of approximately $18.5 billion, of which approximately $1.2 billion, $1.4 billion, $1.3 billion, $2.1 billion, $2.8 billion and $9.7 billion are due in the last six months of 2012, 2013, 2014, 2015, 2016 and thereafter, respectively.

Any incremental firm aircraft orders, including through the exercise of purchase options, will increase the total future capital commitments of the Company, United and/or Continental.

UAL and Continental have concluded their discussions with Boeing regarding delays in delivery of certain Boeing 787 aircraft, and have reached a resolution with Boeing regarding compensation to be received in connection with those delays.

As of June 30, 2012, a substantial portion of UAL’s assets, principally aircraft, spare engines, aircraft spare parts, route authorities and certain other intangible assets, were pledged under various loan and other agreements. We must sustain our profitability and/or access the capital markets to meet our significant long-term debt and capital lease obligations and future commitments for capital expenditures, including the acquisition of aircraft and related spare engines.

Credit Ratings. As of the filing date of this report, UAL, United and Continental had the following corporate credit ratings:

	S&P		Moody’s		Fitch
UAL		B		B2		B
United		B		B2		B
Continental		B		B2		B

These credit ratings are below investment grade levels. Downgrades from these rating levels, among other things, could restrict the availability, or increase the cost of future financing for the Company.

Sources and Uses of Cash

Operating Activities. UAL’s cash flows provided by operations for the six months ended June 30, 2012 was $1.1 billion compared to $1.8 billion in the same period in 2011. The decrease is attributable to a decrease in the Company’s net income year-over-year and the cash flow impact of certain working capital items.

Investing Activities. UAL’s capital expenditures, net of financings, were $552 million and $350 million in the six months ended June 30, 2012 and 2011, respectively. UAL’s capital expenditures for the six months ended June 30, 2012 were primarily attributable to the purchase of new Boeing 737-900ER aircraft and other fleet-related expenditures to improve the onboard experience of our existing aircraft.

In addition to capital expenditures during the six months ended June 30, 2012, Continental acquired six aircraft through the issuance of debt, as discussed under Financing Activities below.

The purchase of short-term investments decreased to $96 million in the six months ended June 30, 2012 from $443 million in the six months ended June 30, 2011.

Financing Activities. In March 2012, Continental created two pass-through trusts, one of which issued $753 million aggregate principal amount of Class A pass-through certificates with a stated interest rate of 4.15% and the other of which issued $139 million aggregate principal amount of Class B pass-through certificates with a stated interest rate of 6.25%. The proceeds of the issuance of the Class A and Class B pass-through certificates, which amounted to $892 million, have been and will be used to purchase equipment notes issued by Continental. Of the $892 million in proceeds raised by the pass-through trusts, Continental received $392 million as of June 30, 2012, in exchange for Continental’s issuance of an equivalent principal amount of equipment notes, which has been recorded as debt. The proceeds have been and are expected to be used to fund the acquisition of new aircraft and, in the case of currently owned aircraft, for general corporate purposes.

During the six months ended June 30, 2012, UAL made debt and capital lease payments of $760 million. These payments include $195 million related to Continental’s Series 2002-1 EETCs.

UAL received $239 million during the first six months of 2011 from Continental’s December 2010 pass-through trust financing. The proceeds in the first six months of 2011 related to the financing of three new and seven currently owned aircraft. The proceeds related to the seven currently owned aircraft were used for general corporate purposes. As noted in Investing Activities above, the financing proceeds related to the acquisition of three new aircraft are not reflected as a financing activity in the consolidated statement of cash flows as the funds are distributed directly to the aircraft supplier. See the 2011 Annual Report for additional information related to this financing.

Commitments, Contingencies and Liquidity Matters

As described in the 2011 Annual Report, the Company’s liquidity may be adversely impacted by a variety of factors, including, but not limited to, obligations associated with fuel hedge settlements and related collateral requirements, pension funding obligations, reserve requirements associated with credit card processing agreements, guarantees, commitments and contingencies. See the 2011 Annual Report and Notes 5, 7, 8 and 9 to the financial statements contained in Part I, Item 1 of this report for information related to these matters.

United and Continental—Results of Operations

In November 2011, the Company received a single operating certificate from the Federal Aviation Administration. The Company plans to merge Continental and United into one legal entity. Once this legal merger occurs, the financial statements of United and Continental will be combined at their historical cost for all periods presented beginning on October 1, 2010, the date on which Continental became a wholly-owned subsidiary of UAL, and there will no longer be a requirement to separately report the historical financial statements of Continental.

44

Until Continental and United are merged into one legal entity, revenue and expenses will continue to be recorded by each entity based on either specific identification of the related transaction, where applicable, or appropriate allocations based on metrics that are systematic and rational. Each airline will continue to record actual expenses for aircraft that are owned or leased and passenger revenue will be determined on an actual basis for the carrier operating the flight.

United

The following table presents information related to United’s results of operations for the three and six months ended June 30 (in millions, except percentage changes):

United had operating income of $84 million and an operating loss of $224 million in the second quarter and first six months of 2012, respectively, as compared to operating income of $437 million and $445 million in the second quarter and first six months of 2011, respectively. As compared to the second quarter of 2011, United’s consolidated revenue decreased $95 million, or 1.7%, to $5.5 billion for the three months ended June 30, 2012. These decreases are due to a decline in cargo revenue in the second quarter and a one-time special revenue item in 2011. United’s consolidated revenue was flat for the six months ended June 30, 2012 as compared to the year-ago period.

Aircraft fuel expense increased 5.2% and 12.7% in the second quarter and first six months of 2012, respectively, as compared to the year-ago periods, which was primarily driven by volatility in market prices for aircraft fuel, as highlighted in the fuel table in Operating Expenses, above. Fuel hedge losses were $17 million in the three months ended June 30, 2012, compared to fuel hedge gains of $213 million in the three months ended June 30, 2011.

Salaries and related costs increased 5.3% and 4.7% in the second quarter and first six months of 2012, respectively, as compared to the year-ago period, which was primarily driven by new collective bargaining agreements for flight attendants and mechanics.

45

Aircraft maintenance materials and outside repairs decreased $8 million, or 2.8%, in the second quarter of 2012 as compared to the year-ago period, primarily due to lower rates on a new engine maintenance contract as well as fewer airframe visits in 2012 as compared to 2011. Similarly, aircraft maintenance materials and outside repairs decreased $33 million, or 5.7%, in the first six months of 2012 as compared to the year-ago period.

Distribution expenses decreased $27 million, or 13.6%, in the second quarter of 2012 as compared to the year-ago period, and decreased $32 million, or 8.3%, in the first six months of 2012 as compared to 2011. These decreases are primarily due to lower credit card discount fees driven by legislation reducing costs on debit card sales and lower rates on global distribution systems fees paid in 2012 as compared to 2011.

United’s nonoperating expense remained flat in the second quarter of 2012 as compared to the year-ago period, and decreased $55 million, or 17.0%, in the first six months of 2012 as compared to the first six months of 2011. This decrease is due to a decrease in interest expense as a result of a decrease in the principal amount of debt outstanding year-over-year.

Continental’s operating income in the second quarter and first six months of 2012 were $494 million and $534 million, respectively, as compared to operating income of $374 million and $403 million, respectively, in the second quarter and first six months of 2011. As compared to the second quarter of 2011, Continental’s consolidated revenue increased $304 million, or 7.1%, to $4.6 billion for the three months ended June 30, 2012. These improvements were largely due to year-over-year capacity discipline, which in turn resulted in higher fares, stronger yields and increased traffic, as compared to the same period in 2011. Similarly, Continental’s consolidated revenue increased $668 million, or 8.5%, to $8.5 billion for the six months ended June 30, 2012 as compared to the year-ago period.

46

Aircraft fuel expense increased approximately 6.1% and 12.2% in both the second quarter and first six months of 2012 as compared to the same period in 2011, primarily due to volatility in the market prices of aircraft fuel. Fuel hedge losses were $21 million and $37 million in the second quarter and first six months of 2012, respectively.

Regional capacity purchase expense increased by 20.6% and 21.9% in both the second quarter and first six months of 2012 as compared to the year-ago periods, which was primarily due to a contractual amendment with one of our regional carrier partners to shift the arrangement from a prorate agreement to a capacity purchase agreement.

Nonoperating expense includes losses from fuel hedge ineffectiveness of $13 million and $2 million, in the second quarter and the first six months of 2012, respectively. Continental’s nonoperating expense in the three months ended June 30, 2012 also includes a net gain of $30 million, associated with marking to market the fair value of derivative assets and liabilities related to agreements that provide for Continental’s convertible debt to be settled with UAL common stock. This net gain and the related derivatives are reflected only in the Continental stand-alone financial statements. See Note 7 to the financial statements included in Part I, Item 1 of this report for additional information.

RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES

The non-GAAP financial measures in this report are presented because they provide management and investors the ability to measure and monitor UAL’s performance on a consistent basis. UAL believes that adjusting for special items is useful to investors because they are non-recurring items not indicative of UAL’s on-going performance. Special items relate to activities that are not central to our ongoing operations. A reconciliation of net income (loss) and diluted earnings (loss) per share to the non-GAAP financial measure of net income and diluted earnings per share, excluding special items, for the three and six months ended June 30, is as follows (in millions, except per share amounts):

	Three Months Ended June 30,							Six Months Ended June 30,
	Net Income		Diluted Earnings per Share		Net Income			Net Income (Loss)			Diluted Earnings (Loss) per Share			Net Income
	2012		2012		2011			2012			2012			2011
Net income (loss) — GAAP	$	339	$	0.89	$	538		$	(109	)	$	(0.33	)	$	325
Special revenue item		—		—		(107	)		—			—			(107	)

CRITICAL ACCOUNTING POLICIES

See Critical Accounting Policies in Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2011 Annual Report for a discussion of the Company’s critical accounting policies. See Note 1 to the financial statements included in Part I, Item I of this report for a discussion of changes in accounting for revenue for the Company’s loyalty program.

FORWARD-LOOKING INFORMATION

Certain statements throughout Management’s Discussion and Analysis of Financial Condition and Results of Operations and elsewhere in this report are forward-looking and thus reflect our current expectations and beliefs with respect to certain current and future events and financial performance. Such forward-looking statements are and will be subject to many risks and uncertainties relating to our operations and business environment that may cause actual results to differ materially from any future results expressed or implied in such forward-looking statements. Words such as “expects,” “will,” “plans,” “anticipates,” “indicates,” “believes,” “forecast,” “guidance,” “outlook” and similar expressions are intended to identify forward-looking statements.

Additionally, forward-looking statements include statements that do not relate solely to historical facts, such as statements which identify uncertainties or trends, discuss the possible future effects of current known trends or uncertainties, or which indicate that the future effects of known trends or uncertainties cannot be predicted, guaranteed or assured. All forward-looking statements in this report are based upon information available to us on the date of this report. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events, changed circumstances or otherwise, except as required by applicable law.

47

The Company’s actual results could differ materially from these forward-looking statements due to numerous factors including, without limitation, the following: its ability to comply with the terms of its various financing arrangements; the costs and availability of financing; its ability to maintain adequate liquidity; its ability to execute its operational plans; its ability to control its costs, including realizing benefits from its resource optimization efforts, cost reduction initiatives and fleet replacement programs; its ability to utilize its net operating losses; its ability to attract and retain customers; demand for transportation in the markets in which it operates; an outbreak of a disease that affects travel demand or travel behavior; demand for travel and the impact that global economic conditions have on customer travel patterns; excessive taxation and the inability to offset future taxable income; general economic conditions (including interest rates, foreign currency exchange rates, investment or credit market conditions, crude oil prices, costs of aviation fuel and energy refining capacity in relevant markets); its ability to cost-effectively hedge against increases in the price of aviation fuel; any potential realized or unrealized gains or losses related to fuel or currency hedging programs; the effects of any hostilities, act of war or terrorist attack; the ability of other air carriers with whom the Company has alliances or partnerships to provide the services contemplated by the respective arrangements with such carriers; the costs and availability of aviation and other insurance; the costs associated with security measures and practices; industry consolidation or changes in airline alliances; competitive pressures on pricing and on demand; its capacity decisions and the capacity decisions of its competitors; U.S. or foreign governmental legislation, regulation and other actions (including open skies agreements and environmental regulations); labor costs; its ability to maintain satisfactory labor relations and the results of the collective bargaining agreement process with its union groups; any disruptions to operations due to any potential actions by its labor groups; weather conditions; the possibility that expected merger synergies will not be realized or will not be realized within the expected time period; and other risks and uncertainties set forth under Item 1A, “Risk Factors” of the 2011 Annual Report, as well as other risks and uncertainties set forth from time to time in the reports the Company files with the SEC.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

There have been no material changes in market risk from the information provided in Item 7A. “Quantitative and Qualitative Disclosures About Market Risk” in our 2011 Annual Report except as follows:

Aircraft Fuel. As of June 30, 2012, UAL’s projected consolidated fuel requirements for the remainder of 2012 were hedged as follows:

	Maximum Price					Minimum Price
	% of Expected Consumption			Weighted Average Price (per gallon)		% of Expected Consumption			Weighted Average Price (per gallon)
Remainder of 2012
Heating oil collars		20	%	$	3.41		20	%	$	2.74
Brent crude oil collars		13			2.74		13			1.93
Diesel fuel collars		9			3.18		9			2.40
Diesel fuel call options		1			3.17		N/A			N/A
Aircraft fuel collars		1			3.00		1			2.35
Aircraft fuel swaps		1			2.72		1			2.72
Total		45	%				44	%

As of June 30, 2012, UAL had also hedged 15% of projected first half 2013 fuel consumption.

At June 30, 2012, UAL fuel derivatives were in a net liability position of $101 million. See Note 7 to the financial statements included in Part I, Item 1 of this report for additional information related to fuel hedges.

Fuel derivative disclosures for United and Continental are omitted under the reduced disclosure format permitted by General Instruction H(2) of Form 10-Q.

ITEM 4. CONTROLS AND PROCEDURES.

UAL, United and Continental each maintain controls and procedures that are designed to ensure that information required to be disclosed in the reports filed or submitted to the SEC is recorded, processed, summarized and reported, within the time periods specified by the SEC’s rules and forms, and is accumulated and communicated to management, including the Chief Executive

48

Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. The management of UAL, United and Continental, including the Chief Executive Officer and Chief Financial Officer, performed an evaluation to conclude with reasonable assurance that UAL’s, United’s and Continental’s disclosure controls and procedures were designed and operating effectively to report the information each company is required to disclose in the reports they file with the SEC on a timely basis. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer of UAL, United and Continental have concluded that as of June 30, 2012, disclosure controls and procedures of each company were effective.

Changes in Internal Control over Financial Reporting during the Quarter Ended June 30, 2012

Except as set forth below, during the three months ended June 30, 2012, there were no changes in UAL’s, United’s or Continental’s internal controls over financial reporting that materially affected, or is reasonably likely to materially affect, their internal controls over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934).

During the first quarter of 2012, we made certain changes to internal controls over financial reporting related to our revenue accounting system and our frequent flyer accounting systems. In connection with our conversion to a single passenger service system in March 2012, United converted from its former revenue accounting system to the Continental revenue accounting system and frequent flyer passenger database. During the second quarter of 2012, we made additional enhancements to the revenue accounting system to improve our internal controls over financial reporting, including a reconciliation of open coupon detail to the general ledger balance of advanced ticket sales. The operating effectiveness of these changes to the internal controls over financial reporting will be evaluated as part of our annual assessment of the effectiveness of internal control over financial reporting as of the end of fiscal year 2012.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

The disclosures below include updates to certain legal proceedings included in the 2011 Annual Report. In addition to the legal proceedings below, UAL, United and Continental are parties to other legal proceedings as described in the 2011 Annual Report and in Part II, Item 1., “Legal Proceedings,” of the Company’s Form 10-Q for the quarter ended March 31, 2012.

Brazil Air Cargo Investigation

On July 31, 2008, state prosecutors in Sao Paulo, Brazil commenced criminal proceedings against eight individuals, including United’s cargo manager, for allegedly participating in cartel activity. Separately, Brazilian antitrust authorities initiated an administrative proceeding in order to verify the existence of a cartel among certain airlines for the determination and implementation of a fuel surcharge, including United and its cargo manager. On January 4, 2010, the Economic Law Secretariat of Brazil issued its opinion recommending that civil penalties be assessed against all parties being investigated, including United, to the Administrative Counsel of Economic Defense (“CADE”), which is charged with making a determination on the matter. On August 30, 2011, the Brazil Federal Public Prosecutor issued an opinion to CADE recommending the dismissal of the proceedings against United and its cargo manager, which is currently under consideration by CADE. United continues to vigorously defend itself before CADE. On May 14, 2012, the criminal proceedings against United’s cargo manager were discontinued.

United is currently cooperating with CADE’s investigation and continues to analyze whether any potential liability may result. Based on its evaluation of all information currently available, United has determined that no reserve for potential liability is required and will continue to defend itself against all allegations that it was aware of or participated in cartel activities. However, penalties for violation of competition laws can be substantial and an ultimate finding that United engaged in improper activity could have a material adverse impact on the Company’s consolidated financial position and results of operations.

ITEM 1A. RISK FACTORS.

See Part I, Item 1A., “Risk Factors,” of the 2011 Annual Report and Part II, Item 1A., “Risk Factors,” of the Company’s Form 10-Q for the quarter ended March 31, 2012 for a detailed discussion of the risk factors affecting UAL, United and Continental.

ITEM 6. EXHIBITS.

A list of exhibits included as part of this Form 10-Q is set forth in an Exhibit Index that immediately precedes the exhibits.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL

INFORMATION OF UNITED AND CONTINENTAL

On May 2, 2010, UAL Corporation, Continental Airlines, Inc. (“Continental”), and JT Merger Sub Inc., a wholly-owned subsidiary of UAL Corporation, entered into an Agreement and Plan of Merger providing for a “merger of equals” business combination. On October 1, 2010, JT Merger Sub Inc. merged with and into Continental, with Continental surviving as a wholly-owned subsidiary of UAL Corporation (the “Merger”). Upon closing of the Merger, UAL Corporation became the parent company of both United Air Lines, Inc. (“United”) and Continental and UAL Corporation’s name was changed to United Continental Holdings, Inc. (“UAL” or the “Company”).

The Company also expects in the future that it will merge Continental and United into one legal entity (the “Airlines Merger”). Once the Airlines Merger occurs, the financial statements of United and Continental will be combined for all periods presented from the date of the Merger at their historical cost, and there will no longer be a requirement to separately report the historical financial statements of Continental.

The Unaudited Pro Forma Condensed Combined Balance Sheet of United and Continental combines the historical consolidated balance sheet of Continental and United as of June 30, 2012. The Unaudited Pro Forma Condensed Combined Statement of Operations of United and Continental for the year ended December 31, 2011 and the six months ended June 30, 2012 combines the historical consolidated statement of operations of Continental and United for each period.

The Unaudited Pro Forma Condensed Combined Financial Statements of United and Continental were prepared by combining the historical financial information of both Continental and United. Pro forma statements that give effect to a business combination to be accounted for as a reorganization of entities under common control combine the historical financial statements of combining entities.

These Unaudited Pro Forma Condensed Combined Financial Statements have been developed from and should be read in conjunction with the consolidated financial statements of Continental and United contained in their respective Annual Reports on Form 10-K for the fiscal year ended December 31, 2011 and their respective Quarterly Reports on Form 10-Q for the six months ended June 30, 2012. The Unaudited Pro Forma Condensed Combined Financial Statements of United and Continental are provided for illustrative purposes only and do not purport to represent what the actual consolidated results of operations or the consolidated financial position of Continental or United would have been had the Airlines Merger occurred on the dates assumed, nor are they necessarily indicative of future consolidated results of operations or consolidated financial position.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS OF UNITED

AND CONTINENTAL

Note 1. Basis of Presentation

On May 2, 2010, UAL Corporation, Continental Airlines, Inc. (“Continental”), and JT Merger Sub Inc., a wholly-owned subsidiary of UAL Corporation, entered into an Agreement and Plan of Merger providing for a “merger of equals” business combination. On October 1, 2010, JT Merger Sub Inc. merged with and into Continental, with Continental surviving as a wholly-owned subsidiary of UAL Corporation (the “Merger”). Upon closing of the Merger, UAL Corporation became the parent company of both United Air Lines, Inc. (“United”) and Continental and UAL Corporation’s name was changed to United Continental Holdings, Inc. (“UAL” or the “Company”).

The Company also expects in the future that it will merge Continental and United into one legal entity (the “Airlines Merger”). Once the Airlines Merger occurs, the financial statements of United and Continental will be combined for all periods presented from the date of the Merger at their historical cost, there will no longer be a requirement to separately report the historical financial statements of Continental, and United will be considered the predecessor.

The Unaudited Pro Forma Condensed Combined Balance Sheet of United and Continental combines the historical consolidated balance sheet of Continental and United on June 30, 2012. The Unaudited Pro Forma Condensed Combined Statement of Operations of United and Continental for the year ended December 31, 2011 and the six months ended June 30, 2012 combines the historical consolidated statement of operations of Continental and United for the year ended December 31, 2011 and the six months ended June 30, 2012, respectively.

The Unaudited Pro Forma Condensed Combined Financial Statements were prepared by combining the historical financial information of both Continental and United. Pro forma statements that give effect to a business combination to be accounted for as a reorganization of entities under common control generally only combine the historical financial statements of combining entities.

Note 2. Pro Forma Adjustments

The Unaudited Pro Forma Condensed Combined Financial Statements of United primarily reflect the elimination of transactions and account balances between Continental and United.

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2011-04 (“ASU 2011-04”), Fair Value Measurement: Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRS. Some of the key amendments to the fair value measurement guidance include the highest and best use and valuation premise for nonfinancial assets, application to financial assets and financial liabilities with offsetting positions in market risks or counterparty credit risk, premiums or discounts in fair value measurement and fair value of an instrument classified in a reporting entity’s shareholders’ equity. Additional disclosures for fair value measurements categorized in Level 3 of the fair value hierarchy include a quantitative disclosure of the unobservable inputs and assumptions used in the measurement, a description of the valuation processes in place, a narrative description of the sensitivity of the fair value to changes in unobservable inputs and interrelationships between those inputs and the level in the fair value hierarchy of items that are not measured at fair value in the consolidated balance sheet but whose fair value must be disclosed. ASU 2011-04 became effective for the Company’s annual and interim periods beginning January 1, 2012, and the required disclosures are disclosed in Note 6 of this report.

FREQUENT FLYER AND PASSENGER REVENUE ACCOUNTING

6 Months Ended

Jun. 30, 2012

FREQUENT FLYER AND PASSENGER REVENUE ACCOUNTING

NOTE 1—FREQUENT FLYER AND PASSENGER REVENUE ACCOUNTING

Frequent Flyer Awards. Effective January 1, 2012, the Company updated its estimated selling price for miles to the contractual rate at which we sell miles to our Star Alliance partners participating in reciprocal frequent flyer programs. This change in estimate has been applied prospectively effective January 1, 2012.

United and Continental account for miles sold and awarded that will never be redeemed by program members, which the Company refers to as “breakage,” using the redemption method. UAL reviews its breakage estimates annually based upon the latest available information regarding redemption and expiration patterns. The Company re-evaluated its population breakage estimates for Continental OnePass miles, which were previously not subject to an expiration policy, and increased the estimate of miles in the population expected to ultimately expire. As a result, the rate at which we recognize redeemed miles has increased.

The Company’s estimate of the expected expiration of miles requires significant management judgment. Current and future changes to expiration assumptions, the expiration policy, program rules or program redemption opportunities may result in material changes to the deferred revenue balance as well as recognized revenues from the Company’s frequent flyer program.

For the three and six months ended June 30, 2012, the combined net impact of these changes to UAL, United and Continental were not material.

Special Revenue. During the second quarter of 2011, the Company modified the previously existing United and Continental co-branded credit card agreements with Chase Bank USA, N.A. This modification resulted in the following one-time adjustment to decrease frequent flyer deferred revenue and increase special revenue in accordance with ASU 2009-13 for the three and six months ended June 30, 2011 as follows (in millions):

	UAL		United		Continental

Integration-related costs include compensation costs related to systems integration and training, costs to repaint aircraft and other branding activities, costs to write-off or accelerate depreciation on systems and facilities that are no longer used or planned to be used for significantly shorter periods, relocation costs for employees and severance primarily associated with administrative headcount reductions. In addition, financial triggering events under the 8% Notes indenture occurred at both June 30, 2012 and 2011 and as a result, UAL became obligated to issue one tranche of $62.5 million in aggregate principal amount of the 8% Notes with respect to each of these financial triggering events. The obligation to issue these tranches was recorded at their fair values of $48 million and $49 million as of June 30, 2012 and 2011, respectively. Both obligations described above were recorded as integration-related costs because the financial results of UAL, excluding Continental’s results, would not have resulted in triggering events under the 8% Notes indenture.

During the three and six months ended June 30, 2012, the Company recorded $76 million and $125 million of severance and benefits associated with three voluntary employee programs, respectively. During the first quarter of 2012, approximately 400 mechanics offered to retire early in exchange for a cash severance payment that was based on the number of years of service each employee had accumulated. The Company also offered a voluntary leave of absence program that approximately 1,800 flight attendants accepted, which allows for continued medical coverage during the leave of absence period. During the second quarter of 2012, as part of the recently amended collective bargaining agreement with the Association of Flight Attendants, the Company offered a voluntary program for flight attendants at United to retire early in exchange for a cash severance payment. The payments are dependent on the number of years of service each employee has accumulated. Approximately 1,300 flight attendants accepted this program and the Company estimates the amount for this voluntary program to be approximately $76 million.

In addition, the Company sold nine aircraft during the first six months of 2012, of which three were sold during the second quarter. The Company also made adjustments to certain legal reserves.

The Company expects to consolidate its headquarters facilities by the middle of 2013. During the consolidation process, the Company expects to record special charges for accelerated depreciation and lease expense on unused facilities associated with the facility that it vacates. The Company estimates that these charges will be approximately $60 million to $80 million in total, which are expected to be recorded in late 2012 through 2013.

Accruals

The accrual for severance and medical costs was $153 million, $137 million and $16 million related to UAL, United and Continental, respectively, as of June 30, 2012. In addition, the accrual balance of future lease payments on permanently grounded aircraft was $8 million for both UAL and United as of June 30, 2012.

The severance-related accrual as of June 30, 2012, which primarily relates to the integration of United and Continental, is expected to be paid through 2014. Lease payments for grounded aircraft are expected to continue through 2013.

At June 30, 2011, the accrual balance for severance and medical costs was $70 million, $40 million and $30 million, related to UAL, United and Continental, respectively. In addition, the accrual balance of future lease payments on permanently grounded aircraft was $34 million for both UAL and United as of June 30, 2011.

RELATED PARTY TRANSACTIONS

NOTE 11—RELATED PARTY TRANSACTIONS

Intercompany transactions—United and Continental

United and Continental perform services for one another including various aircraft maintenance services and aircraft ground handling at certain airports, and they utilize one management team to oversee the sales and administrative functions of both airlines. For services provided, Continental paid United $268 million and United paid Continental $230 million during the quarter ended June 30, 2012. These payments do not include interline billings, which are common among airlines for transportation-related services. Most of these transactions are routinely settled through the clearing house, which is customarily used in the monthly settlement of such items. Transactions not settled through the clearing house are typically settled in cash on a quarterly basis. As of June 30, 2012, Continental had a net current payable of $2.2 billion to United primarily related to the transfer of the current portion of the frequent flyer liability and the cash transfer from United in conjunction with the conversion to the new passenger service system, as described below. In addition, Continental had a $0.7 billion noncurrent payable to United associated with the transfer of the long-term portion of the frequent flyer liability.

Frequent flyer program transition

In the first quarter of 2012, the Company moved to a single loyalty program. Continental’s loyalty program formally ended in the first quarter of 2012, at which point United automatically enrolled Continental OnePass program members in the MileagePlus program and deposited into those MileagePlus accounts award miles equal to these members’ OnePass award miles balance. In March 2012, the related frequent flyer deferred revenue and advance purchase of miles liabilities for the OnePass program was transferred to United with a corresponding liability recorded by Continental payable to United for assuming the frequent flyer obligations. No gain or loss was incurred from the transaction as the liabilities were transferred at their respective net book value. The obligation associated with this transfer will be settled by Continental through future redemptions by MileagePlus members on Continental operated flights.

Passenger service system and ticket stock integration

In March 2012, Continental and United converted to a single passenger service system, allowing the Company to operate using a single reservations system, carrier code, flight schedule, website and departure control system. In conjunction with the conversion to a single passenger service system, all tickets are now sold by United. As a result, the air traffic liability of Continental is diminishing as tickets previously sold by Continental are used or refunded and United’s advanced ticket sales liability and associated cash receipts from the ticket sales will increase accordingly. Subsequent to the system conversion, United transferred cash to Continental each month, such transfers being netted against amounts owed to Continental for segments flown by Continental on United ticket stock. Revenue will continue to be recorded by the carrier that is operating the flight.

Revenue and expense allocation

In November 2011, the Company received a single operating certificate from the Federal Aviation Administration. The Company plans to merge Continental and United into one legal entity. Once this legal merger occurs, the financial statements of United and Continental will be combined at their historical cost for all periods presented beginning on October 1, 2010, the date on which Continental became a wholly-owned subsidiary of UAL, and there will no longer be a requirement to separately report the historical financial statements of Continental.

Until Continental and United are merged into one legal entity, revenue and expenses will continue to be recorded by each entity based on either specific identification of the related transaction, where applicable, or appropriate allocations based on metrics that are systematic and rational. Certain revenues and expenses that were previously recorded based on a specific identification were allocated in March 2012 in connection with the conversion to a single passenger service system. We believe the allocated amounts will generally be comparable to historical amounts. Each airline will continue to record actual expenses for aircraft that are owned or leased and passenger revenue will be determined on an actual basis for the carrier operating the flight. The table below illustrates a summary of the primary allocation metrics to be used:

Account	Allocation metric between subsidiaries
Operating revenue:
Passenger	Actual ticket revenue based on specifically identified flights operated by each carrier. Frequent flyer component of passenger revenue based on historic revenue passenger miles (“RPMs”) split between carriers. Regional revenue, based on the carrier that contracted with the regional carrier
Cargo	Actual by operating carrier
Other operating	Passenger related based on passenger revenue and other based on passengers enplaned or other similar criteria
Operating expense:
Aircraft fuel	Actual by operating carrier
Salaries and related costs	Actual for operational workgroups and allocation based on historical RPMs for administrative personnel. Profit sharing expense is allocated based on the proportional profit of each operating entity
Regional capacity purchase	Actual based on specific identification of the carrier that contracted with regional carrier for flying
Landing fees and other rent	Allocation based on passengers enplaned
Aircraft maintenance materials and outside repairs	Actual based on the specific identification of each carrier’s aircraft
Depreciation and amortization	Specific identification of carriers’ operational assets (i.e. flight equipment) and intangible assets and allocation based on historical RPMs for other assets
Distribution expenses	Allocation based on passenger revenue
Aircraft rent	Actual based on specific identification of each carrier’s aircraft
Special charges	Specific identification
Other operating expenses	Specific identification where applicable and allocation based on historical RPMs for other

During the six months ended June 30, 2012, Continental contributed $75 million to its tax-qualified defined benefit pension plans. Continental contributed an additional $41 million to its tax-qualified defined benefit pension plans in July 2012.

Share-Based Compensation. In February 2012, UAL granted share-based compensation awards pursuant to the United Continental Holdings, Inc. 2008 Incentive Compensation Plan. These share-based compensation awards include approximately 0.5 million shares of restricted stock and 0.6 million restricted stock units (“RSUs”) that vest pro-rata over three years on the anniversary of the grant date. In addition, UAL granted 1.3 million performance-based RSUs which will vest based on UAL’s return on invested capital for the three years ending December 31, 2014. If this performance condition is achieved, cash payments will be made after the end of the performance period based on the 20-day average closing price of UAL common stock immediately prior to the vesting date. The Company accounts for the RSUs as liability awards. The table below presents information related to share-based compensation (in millions):

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2011		2012		2011
Share-based compensation expense (a)	$	11	$	14	$	26	$	27

	June 30, 2012		December 31, 2011
Unrecognized share-based compensation expense	$	47	$	43

(a) Includes $3 million and $7 million of expense recognized in integration-related costs for the three and six months ended June 30, 2012, respectively. Includes $6 million and $9 million of expense recognized in integration-related costs for the three and six months ended June 30, 2011, respectively.

Profit Sharing Plans. In 2012, substantially all employees participate in profit sharing, which pays 15% of total pre-tax earnings, excluding special items and share-based compensation expense, to eligible employees when pre-tax profit, excluding special items, profit sharing expense and share-based compensation program expense, exceeds $10 million. Eligible U.S. co-workers in each participating work group receive a profit sharing payout using a formula based on the ratio of each qualified co-worker’s annual eligible earnings to the eligible earnings of all qualified co-workers in all domestic workgroups. The international profit sharing plan pays eligible non-U.S. co-workers the same percentage of eligible pay that is calculated under the U.S. profit sharing plan. UAL recorded $54 and $90 million of profit sharing and related payroll tax expense in the six months ended June 30, 2012 and 2011, respectively. Profit sharing expense is recorded as a component of salaries and related costs in the consolidated statements of operations.

INCOME TAXES

INCOME TAXES

NOTE 4—INCOME TAXES

Our effective tax rates are lower than the federal statutory rate of 35% primarily because of the impact of changes to existing valuation allowances. We continue to provide a valuation allowance for our deferred tax assets in excess of deferred tax liabilities because we have concluded that it is more likely than not that such deferred tax assets will ultimately not be realized.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including the reversals of deferred tax liabilities) during the periods in which those deferred tax assets will become deductible. The Company’s management assesses available positive and negative evidence regarding the realizability of its deferred tax assets, and records a valuation allowance when it is more likely than not that all or a portion of the deferred tax assets will not be realized. To form a conclusion, management considers positive evidence in the form of reversing temporary differences, projections of future taxable income and tax planning strategies, and negative evidence such as recent history of losses. Although the Company was no longer in a three-year cumulative loss position at the end of 2011, management determined that the size and frequency of financial losses in recent years and the uncertainty associated with projecting future taxable income supported the conclusion that the valuation allowance was still needed on net deferred tax assets. If UAL achieves significant profitability in 2012, then management will evaluate whether its recent history of profitability constitutes sufficient positive evidence to support a reversal of a portion, or all, of the remaining valuation allowance.

COMMITMENTS AND CONTINGENCIES

Jun. 30, 2012

COMMITMENTS AND CONTINGENCIES

NOTE 8—COMMITMENTS AND CONTINGENCIES

General Guarantees and Indemnifications. In the normal course of business, the Company enters into numerous real estate leasing and aircraft financing arrangements that have various guarantees included in the contracts. These guarantees are primarily in the form of indemnities under which the Company typically indemnifies the lessors and any tax/financing parties against tort liabilities that arise out of the use, occupancy, operation or maintenance of the leased premises or financed aircraft. Currently, the Company believes that any future payments required under these guarantees or indemnities would be immaterial, as most tort liabilities and related indemnities are covered by insurance (subject to deductibles). Additionally, certain leased premises such as fueling stations or storage facilities include indemnities of such parties for any environmental liability that may arise out of or relate to the use of the leased premises.

Legal and Environmental Contingencies. The Company has certain contingencies resulting from litigation and claims incident to the ordinary course of business. Management believes, after considering a number of factors, including (but not limited to) the information currently available, the views of legal counsel, the nature of contingencies to which the Company is subject and prior experience, that the ultimate disposition of these contingencies will not materially affect the Company’s consolidated financial position or results of operations.

The Company records liabilities for legal and environmental claims when a loss is probable and reasonably estimable. These amounts are recorded based on the Company’s assessments of the likelihood of their eventual disposition.

Commitments. On July 12, 2012, UAL entered into a purchase agreement with The Boeing Company (“Boeing”) for a firm narrowbody aircraft order of 100 Boeing 737 MAX 9 aircraft, with options to purchase an additional 100 Boeing 737 MAX 9 aircraft (the “737 MAX 9 Agreement”). Also on July 12, 2012, United entered into a purchase agreement with Boeing for a firm narrowbody aircraft order of 50 Boeing 737-900ER aircraft, with options to purchase an additional 60 Boeing 737-900ER aircraft. The firm order 50 Boeing 737-900ER aircraft and 100 Boeing 737 MAX 9 aircraft are expected to be delivered between 2013 and 2022.

The July 2012 Boeing aircraft order is part of the Company’s flexible fleet strategy, which provides the Company the ability to replace older, less fuel efficient aircraft and to adjust the size of its fleet to respond to market conditions and opportunities. Specifically, the Boeing 737-900ER order discussed above would largely serve as replacement for Boeing 757-200 aircraft that are operated by United whose leases expire over the next five years.

United Aircraft Commitments. As of June 30, 2012 (adjusted to include the order discussed above), United had firm commitments to purchase 100 new aircraft (25 Boeing 787 aircraft, 50 Boeing 737-900ER aircraft and 25 Airbus A350XWB aircraft) scheduled for delivery from 2013 through 2019. United also has options and purchase rights for 152 additional Boeing and Airbus aircraft.

Continental Aircraft Commitments. As of June 30, 2012 (adjusted to include the order discussed above) Continental had firm commitments to purchase 72 new aircraft (47 Boeing 737 aircraft and 25 Boeing 787 aircraft) scheduled for delivery from 2012 through 2016. Continental also has options to purchase 89 Boeing aircraft. From July 1, 2012 through December 31, 2012, Continental expects to take delivery of nine Boeing 737-900ER aircraft and five Boeing 787-8 aircraft.

United has secured considerable backstop financing commitments from its widebody aircraft and engine manufacturers, subject to certain customary conditions. In addition, Continental has arranged for financing of five Boeing 737-900ER aircraft and four Boeing 787-8 aircraft scheduled for delivery from July 2012 through December 2012. See Note 9 of this report for additional information. However, UAL and United do not have backstop financing or any other financing currently in place for their firm narrowbody aircraft orders with Boeing, and Continental does not have backstop financing or any other financing currently in place for its other Boeing aircraft on order. Financing will be necessary to satisfy the Company’s capital commitments for its firm order aircraft and other related capital expenditures. The Company can provide no assurance that any financing not already in place for aircraft and spare engine deliveries will be available to the Company on acceptable terms when necessary or at all.

The table below summarizes the capital commitments of the Company, United and Continental as of June 30, 2012, which primarily relate to the acquisition of aircraft and related spare engines, aircraft improvements and acquisition of information technology services and assets. The table below is adjusted to include the impact of the July 2012 Boeing 737-900ER and 737 MAX 9 aircraft orders discussed above. As UAL has the right, and intends in the future, to assign its interest under the 737 MAX 9 Agreement with respect to one or more of the Boeing 737 MAX 9 aircraft to either United or Continental, but has not determined the actual assignment of the Boeing 737 MAX 9 between United and Continental, the table below assumes that 50% of the Boeing 737 MAX 9 order is assigned to United and 50% of the Boeing 737 MAX 9 order is assigned to Continental. The table below is also adjusted to include the impact of the resolution between the Company and Boeing in July 2012 relating to compensation in connection with certain Boeing 787 aircraft delivery delays, which contemplates certain adjustments to Continental’s and United’s Boeing 787 purchase agreements.

Any incremental firm aircraft orders, including through the exercise of purchase options, will increase the total future capital commitments of the Company, United and/or Continental.

UAL and Continental have concluded their discussions with Boeing regarding delays in delivery of certain Boeing 787 aircraft, and have reached a resolution with Boeing regarding compensation to be received in connection with those delays.

Credit Card Processing Agreements. United and Continental have agreements with financial institutions that process customer credit card transactions for the sale of air travel and other services. Under certain of United’s and Continental’s credit card processing agreements, the financial institutions either require, or under certain circumstances have the right to require, that United and Continental maintain a reserve equal to a portion of advance ticket sales that have been processed by that financial institution, but for which United and Continental have not yet provided the air transportation.

As of June 30, 2012, $25 million was provided by the Company as a cash reserve for its credit card processing agreement with JPMorgan Chase Bank, N.A. and Paymentech, LLC. Our credit card processing agreement with JPMorgan Chase Bank, N.A. and Paymentech, LLC to process MasterCard/Visa transactions and our credit card processing agreement with American Express allow the applicable financial institution to require additional cash or other collateral reserves to be established or additional withholding of payments related to receivables collected if the Company does not maintain certain minimum levels of unrestricted cash, cash equivalents and short term investments. The Company’s current level of unrestricted cash, cash equivalents and short term investments is substantially in excess of these minimum levels. The amount of required cash or other collateral reserves or withheld payments would be no more than the liability of the credit card processor for tickets purchased with the applicable credit cards for travel that had not occurred. In conjunction with the single passenger service system conversion in March 2012, all tickets sold since that date have been on United ticket stock. As a result, the advance ticket sales by Continental have diminished and are expected to be zero by March 2013.

Guarantees and Off-Balance Sheet Financing.

Guarantees. United and Continental are the guarantors of approximately $270 million and $1.7 billion, respectively, in aggregate principal amount of tax-exempt special facilities revenue bonds and interest thereon. These bonds, issued by various airport municipalities, are payable solely from rentals paid under long-term agreements with the respective governing bodies. The leasing arrangements associated with $1.8 billion ($270 million for United and $1.5 billion for Continental) of these obligations are accounted for as operating leases with the associated expense recorded on a straight-line basis resulting in ratable accrual of the lease obligation over the expected lease term. The leasing arrangements associated with $190 million (for Continental only) of these obligations are accounted for as capital leases. These bonds are due between 2015 and 2033.

In the Company’s financing transactions that include loans, the Company typically agrees to reimburse lenders for any reduced returns with respect to the loans due to any change in capital requirements and, in the case of loans in which the interest rate is based on the London Interbank Offered Rate (“LIBOR”), for certain other increased costs that the lenders incur in carrying these loans as a result of any change in law, subject in most cases to obligations of the lenders to take certain limited steps to mitigate the requirement for, or the amount of, such increased costs. At June 30, 2012, UAL had $2.5 billion of floating rate debt (consisting of United’s $2.0 billion and Continental’s $498 million of debt) and $376 million of fixed rate debt (consisting of United’s $195 million and Continental’s $181 million of debt), with remaining terms of up to ten years, that are subject to these increased cost provisions. In several financing transactions involving loans or leases from non-U.S. entities, with remaining terms of up to ten years and an aggregate balance of $2.8 billion (consisting of United’s $2.2 billion and Continental’s $595 million balance), the Company bears the risk of any change in tax laws that would subject loan or lease payments thereunder to non-U.S. entities to withholding taxes, subject to customary exclusions.

Houston Bush Terminal B Redevelopment Project. In May 2011, UAL, in partnership with the Houston Airport System, announced that it would begin construction of the first phase of a potential three-phase $1 billion terminal improvement project for Terminal B at George Bush Intercontinental Airport (“Houston Bush”) by the end of 2011. In November 2011, the City of Houston issued approximately $113 million of special facilities revenue bonds to finance the construction of a new south concourse at Houston Bush dedicated to the Company’s regional jet operations. The bonds are guaranteed by Continental and are payable from certain rentals paid by Continental under a special facilities lease agreement with the City of Houston. Continental’s initial commitment is to construct the first phase of the originally anticipated three-phase project. Continental’s cost of construction of phase one of the project is currently estimated to be approximately $100 million and is funded by special facilities revenue bonds. Construction of the remaining phases of the project, if any, will be based on demand over the next seven to 10 years, with phase one currently expected to be completed in late 2013.

Based on a qualitative assessment of the Houston Bush Terminal B Redevelopment Project, due to the fact that Continental is guaranteeing the special facilities revenue bonds and the requirement that Continental fund cost overruns with no stated limits, Continental is considered the owner of the property during the construction period for accounting purposes. As a result, the construction project is being treated as a financing transaction such that the property and related financing will be included on UAL’s consolidated balance sheet as an asset under operating property and equipment and as a construction obligation under other long-term liabilities.

Credit Facilities. As of June 30, 2012 the Company had its entire commitment capacity of $500 million available under the Credit and Guaranty Agreement, dated as of December 22, 2011 (the “Revolving Credit Facility”) with a syndicate of banks led by Citibank N.A., as administrative agent. The Revolving Credit Facility has an expiration date of January 30, 2015.

Labor Negotiations. As of June 30, 2012, UAL and its subsidiaries had approximately 88,000 active employees, of whom approximately 80% are represented by various U.S. labor organizations. On February 27, 2012, the pilots at both United and Continental agreed to an extension of their protocol for joint negotiations and continue to engage in joint bargaining with the Company. On February 28, 2012, the flight attendants at United ratified a new collective bargaining agreement and, on July 13, 2012, the flight attendants at Continental ratified a new collective bargaining agreement. On July 17, 2012, the Company reached a tentative agreement with its Continental Micronesia flight attendants, subject to ratification in the third quarter of 2012. Joint negotiations will begin shortly for a joint collective bargaining agreement covering the Company’s flight attendant work groups.

On March 7, 2012, the passenger service employees at both United and Continental voted to be represented by the International Association of Machinists and Aerospace Workers, AFL-CIO and negotiations are underway for a joint collective bargaining agreement for this employee group. The Company reached a tentative agreement with the United ground instructors, which the United ground instructors ratified on June 8, 2012. We are continuing our negotiations for joint collective bargaining agreements with other work groups, including technicians, dispatchers, fleet service employees, storekeepers and various smaller groups.

The earnings impact is classified in “Nonoperating income (expense) - Miscellaneous, net” in Continental’s statements of consolidated operations.

As of June 30, 2012, Continental’s auction rate securities, which had a par value of $135 million and an amortized cost basis of $112 million, were variable-rate debt instruments with contractual maturities generally greater than ten years and with interest rates that reset every 7, 28 or 35 days, depending on the terms of the particular instrument. These securities are backed by pools of student loans guaranteed by state-designated guaranty agencies and reinsured by the U.S. government. All of the auction rate securities that Continental holds are senior obligations under the applicable indentures authorizing the issuance of the securities.

As of June 30, 2012, United’s EETC securities have an amortized cost basis of $64 million and unrealized losses of $1 million. All changes in the fair value of these investments have been classified within accumulated other comprehensive income.

Continental’s debt-related derivatives presented in the tables above relate to (a) supplemental indenture agreements that provide that Continental’s convertible debt, which was previously convertible into shares of Continental common stock, is convertible into shares of UAL common stock upon the terms and conditions specified in the indentures, and (b) the embedded conversion options in Continental’s convertible debt that are required to be separated and accounted for as though they are free-standing derivatives as a result of the Continental debt becoming convertible into the common stock of a different reporting entity. These derivatives are reported in Continental’s separate financial statements and eliminated in consolidation for UAL.

Quantitative Information About Level 3 Fair Value Measurements as of June 30, 2012 ($ in millions)

Item	Fair Value at June 30, 2012			Valuation Technique	Unobservable Input	Range (Weighted Average)
Auction rate securities	$	112		Discounted Cash Flows	Credit risk premium (a) Illiquidity premium (b) Expected repayments (c)	1% 5% Assumed repayment in years 2013 through 2036

Convertible debt option liability	$	(147	)	Binomial Lattice Model	Expected volatility (e) Own credit risk (f)	45% - 60% (48%) 7% - 10% (8%)

(a) Represents the credit risk premium component of the discount rate that the Company has determined market participants would use in pricing the investments.

(b) Represents the illiquidity premium component of the discount rate that the Company has determined market participants would use in pricing the investments.

(c) Represents the estimated timing of principal repayments used in the discounted cash flow model.

(d) Represents the credit risk premium of the EETC structure above the risk-free rate that the Company has determined market participants would use in pricing the instruments.

(e) Represents the range in volatility estimates that the Company has determined market participants would use when pricing the instruments.

(f) Represents the range of Company-specific risk adjustments that the Company has determined market participants would use as a model input.

Valuation Processes—Level 3 Measurements—The Company’s internal valuation group is responsible for determining the fair value of financial instruments. Depending on the instrument, the valuation group utilizes discounted cash flow methods or option pricing methods as indicated above. Valuations using discounted cash flow methods are generally conducted by the valuation group. Valuations using option pricing models are generally provided to the Company by third-party valuation experts. Each reporting period, the valuation group reviews the unobservable inputs used by third-party valuation experts for reasonableness utilizing relevant information available to the Company from other published sources. The Company has a formal process to review changes in fair value for satisfactory explanation.

Sensitivity Analysis—Level 3 Measurements—Changes in the unobservable input values would be unlikely to cause material changes in the fair value of the auction rate securities and EETCs.

The significant unobservable inputs used in the fair value measurement of the Continental convertible debt derivative assets and liabilities are the UAL stock expected volatility and the Company’s own credit risk. Significant increases (decreases) in expected volatility would result in a higher (lower) fair value measurement. Significant increases (decreases) in the Company’s own credit risk would result in a lower (higher) fair value measurement. A change in one of the inputs would not necessarily result in a directionally similar change in the other.

Fair value of the financial instruments included in the tables above was determined as follows:

Description	Fair Value Methodology
Cash and Cash Equivalents	The carrying amounts approximate fair value because of the short-term maturity of these assets.
Short-term Investments, Investments, and Restricted Cash	Fair value is based on (a) the trading prices of the investment or similar instruments, (b) an income approach, which uses valuation techniques to convert future amounts into a single present amount based on current market expectations about those future amounts when observable trading prices are not available, or (c) internally-developed models of the expected future cash flows related to the securities. These assets have maturities of less than one year except for the EETCs, auction rate securities and corporate debt.
Fuel Derivatives	Derivative contracts are privately negotiated contracts and are not exchange traded. Fair value measurements are estimated with option pricing models that employ observable inputs. Inputs to the valuation models include contractual terms, market prices, yield curves, fuel price curves and measures of volatility, among others.
Foreign Currency Derivatives	Fair value is determined with a formula utilizing observable inputs. Significant inputs to the valuation models include contractual terms, risk-free interest rates and forward exchange rates.
Debt	Fair values were based on either market prices or the discounted amount of future cash flows using our current incremental rate of borrowing for similar liabilities.
Convertible Debt Derivative Asset and Option Liability	The Company used a binomial lattice model to value the conversion options and the supplemental derivative assets. Significant binomial model inputs that are not objectively determinable include volatility and discount rate.

HEDGING ACTIVITIES

NOTE 7—HEDGING ACTIVITIES

Aircraft Fuel Hedges. The Company has a risk management strategy to hedge a portion of its price risk related to projected aircraft fuel requirements. The Company periodically enters into derivative contracts to mitigate the adverse financial impact of potential increases in the price of fuel. The Company does not enter into derivative instruments for speculative, non-risk management purposes.

Upon proper qualification, the Company accounts for its fuel derivative instruments as cash flow hedges. All derivatives designated as hedges that meet certain requirements are granted special hedge accounting treatment. Generally, utilizing the special hedge accounting, all periodic changes in fair value of the derivatives designated as hedges that are considered to be effective are recorded in accumulated other comprehensive income (loss) (“AOCI”) until the underlying fuel is consumed and recorded in fuel expense. The Company is exposed to the risk that its hedges may not be effective in offsetting changes in the cost of fuel and that its hedges may not continue to qualify for special hedge accounting. Hedge ineffectiveness results when the change in the fair value of the derivative instrument exceeds the change in the value of the Company’s expected future cash outlay to purchase and consume fuel. To the extent that the periodic changes in the fair value of the derivatives are not effective, that ineffectiveness is classified as other nonoperating income (expense).

The Company records each derivative instrument as a derivative asset or liability on a gross basis in its consolidated balance sheets and, accordingly, records any related collateral on a gross basis.

As of June 30, 2012, our projected fuel requirements for the remainder of 2012 were hedged as follows:

	Maximum Price					Minimum Price
	% of Expected Consumption			Weighted Average  Price (per gallon)		% of Expected Consumption			Weighted Average  Price (per gallon)
UAL (a)
Heating oil collars		20	%	$	3.41		20	%	$	2.74
Brent crude oil collars		13			2.74		13			1.93

Aircraft fuel collars		1			3.00		1			2.35
Aircraft fuel swaps		1			2.72		1			2.72
Total		45	%				44	%

(a) As of June 30, 2012, UAL had also hedged 15% of projected first half 2013 fuel consumption.

Derivative Credit Risk and Fair Value

The Company is exposed to credit losses in the event of nonperformance by counterparties to its derivative instruments. While the Company records derivative instruments on a gross basis, the Company monitors its net derivative position with each counterparty to monitor credit risk. Based on the fair value of our fuel derivative instruments, our counterparties may require us to post collateral when the price of the underlying commodity decreases, and we may require our counterparties to provide us with collateral when the price of the underlying commodity increases. The following table presents information related to the Company’s derivative credit risk as of June 30, 2012 (in millions):

	UAL		United		Continental
Net derivative liability with counterparties	$	101	$	54	$	47

DEBT

DEBT

NOTE 9—DEBT

As of June 30, 2012, a substantial portion of our assets are pledged as collateral for our debt. These assets principally consist of aircraft and the related spare parts and engines, route authorities and loyalty program intangible assets. As of June 30, 2012, UAL, United and Continental were in compliance with their respective debt covenants.

Continental EETCs. In March 2012, Continental created two pass-through trusts, one of which issued $753 million aggregate principal amount of Class A pass-through certificates with a stated interest rate of 4.15% and the other of which issued $139 million aggregate principal amount of Class B pass-through certificates with a stated interest rate of 6.25%. The proceeds of the issuance of the Class A and Class B pass-through certificates, which amounted to $892 million, have been and will be used to purchase equipment notes issued by Continental. Of the $892 million in proceeds raised by the pass-through trusts, Continental received $392 million as of June 30, 2012, in exchange for Continental’s issuance of an equivalent principal amount of equipment notes, which has been recorded as debt. The remaining amount is expected to be received during the last six months of this year as aircraft are delivered to Continental and Continental issues equipment notes to the trusts. Continental records the debt obligation upon issuance of the equipment notes rather than upon the initial issuance of the pass-through certificates. The proceeds have been and are expected to be used to fund the acquisition of new aircraft, and in the case of currently owned aircraft, for general corporate purposes.

The Company evaluated whether the pass-through trusts formed are variable interest entities (“VIEs”) required to be consolidated by the Company under applicable accounting guidance, and determined that the pass-through trusts are VIEs. The Company determined that it does not have a variable interest in the pass-through trusts. The Company does not invest in or obtain a financial interest in the pass-through trusts. Rather, Continental has an obligation to make interest and principal payments on its equipment notes held by the pass-through trusts. The Company did not intend to have any voting or non-voting equity interest in the pass-through trusts or to absorb variability from the pass-through trusts. Based on this analysis, the Company determined that it is not required to consolidate the pass-through trusts.

8% Contingent Senior Notes. UAL is obligated under an indenture to issue to the Pension Benefit Guaranty Corporation (“PBGC”) up to $500 million aggregate principal amount of 8% Notes in up to eight equal tranches of $62.5 million if certain financial triggering events occur (with each tranche issued no later than 45 days following the end of any applicable fiscal year).

During 2011, a financial triggering event under the 8% Notes indenture occurred at both June 30, 2011 and December 31, 2011 and, as a result, UAL issued two tranches of $62.5 million each of the 8% Notes in January 2012, which were recorded during 2011 at their fair value of $88 million as a component of integration costs. In addition, at June 30, 2012, a financial triggering event under the 8% Notes indenture occurred and, as a result, UAL is obligated to issue an additional tranche of $62.5 million of the 8% Notes by February 2013. UAL recorded a liability for the fair value of the obligation of $48 million during the second quarter of 2012.

UAL’s 6% Senior Notes due 2031 (the “6% Senior Notes”), with a principal amount of $652 million as of June 30, 2012, and the $125 million of UAL’s 8% Contingent Senior Notes (the “8% Notes”) issued by UAL in January 2012, are redeemable with either cash or shares of UAL common stock, or in the case of mandatory redemption, a combination thereof, at UAL’s option. The Company is obligated to issue an additional $62.5 million of the 8% Notes by February 2013, which are also redeemable on the same terms as the 6% Senior Notes and the other 8% Notes. These notes are not included in the diluted earnings (loss) per share calculation because it is UAL’s intent to redeem these notes with cash if UAL were to decide to redeem these notes.

During the second quarter of 2011, UAL repurchased at par value approximately $570 million of the $726 million outstanding principal amount of its 4.5% Senior Limited-Subordination Convertible Notes due 2021 (the “4.5% Notes”) with cash after the 4.5% Notes were put to UAL by the noteholders. For the three and six months ended June 30, 2011, the dilutive effect of the 4.5% Notes was excluded from the diluted earnings per share calculations from the date that notice was given of the Company’s intent to pay the notes put to it in cash up to the June 30, 2011 repurchase date.
