Exhibit 99.1

This investor update provides guidance and certain forward looking statements about United Continental Holdings, Inc. (the “Company” or “UAL”). The information in this investor update contains preliminary financial and operational results for the Company for third-quarter 2014.

Capacity

The Company’s third-quarter 2014 consolidated system available seat miles (“ASMs”) increased an estimated 0.5% as compared to the same period in the prior year. UAL’s third-quarter 2014 consolidated domestic ASMs decreased approximately 1.2% and consolidated international ASMs increased an estimated 2.7% versus the third quarter of 2013.

Revenue

The Company’s third-quarter 2014 consolidated passenger revenue per available seat mile (“PRASM”) increased approximately 3.5% - 4.0% percent versus the third quarter of 2013.

The Company expects its third-quarter 2014 cargo revenue to be between $225 million and $245 million and expects its third-quarter 2014 other revenue to be between $1.00 billion and $1.02 billion.

Non-Fuel Expense

UAL expects its third-quarter consolidated cost per ASM (“CASM”), excluding profit sharing, fuel, third-party business expense and special charges, to increase approximately 1.0% year-over-year.

The Company expects to record approximately $65 million of third-party business expense in the third quarter of 2014. Corresponding third-party business revenue associated with third-party business activities is recorded in other revenue.

Fuel Expense

UAL estimates its consolidated fuel price, including the impact of cash-settled hedges, to be $3.01 per gallon for third-quarter 2014.

Nonoperating Expense

The Company estimates nonoperating expense to be between $150 million and $170 million, excluding non-cash gains/losses on fuel hedges, for third-quarter 2014.

Profit Sharing and Share-Based Compensation

For 2014, the Company will pay approximately 10% of total adjusted earnings as profit sharing to employees for adjusted earnings up to a 6.9% adjusted pre-tax margin and approximately 14% for any adjusted earnings above that amount. Adjusted earnings for the purposes of profit sharing are calculated as GAAP pre-tax earnings, excluding special items, profit sharing expense and share-based compensation program expense. Share-based compensation expense for the purposes of the profit sharing calculation is estimated to be $66 million year to date through the third quarter of 2014.

Capital Expenditures and Scheduled Debt and Capital Lease Payments

The Company expects between $470 million and $490 million of gross capital expenditures in the third quarter of 2014, which is below previous guidance. The difference versus prior guidance is primarily attributable to certain capital expenditures having shifted from the third to the fourth quarter of 2014. There is no impact to full-year 2014 capital expenditure guidance.

The Company expects debt and capital lease payments to total approximately $1.1 billion in the third quarter of 2014. The difference versus prior guidance is primarily attributable to the redemption of the entire $800 million of 6.75% notes due 2015. Within the quarter, the company also issued an additional $500 million tranche of term loan debt.

Liquidity Position

UAL ended the third quarter of 2014 with approximately $6.8 billion in unrestricted liquidity comprised of approximately $5.5 billion of unrestricted cash, cash equivalents and short-term investments and $1.35 billion in undrawn commitments under its revolving credit facility.

Share Count

These share count charts are based upon several assumptions including market stock price and number of shares outstanding. The number of shares used in the actual earnings per share calculation will likely be different from those set forth below.

Non-GAAP to GAAP Reconciliations

UAL evaluates its financial performance utilizing various accounting principles generally accepted in the United States of America (“GAAP”) and Non-GAAP financial measures, including net income/loss, net earnings/loss per share and CASM, among others. Non-GAAP financial measures are presented because they provide management and investors the ability to measure and monitor UAL’s performance on a consistent basis. CASM is a common metric used in the airline industry to measure an airline’s cost structure and efficiency. Pursuant to SEC Regulation G, UAL has included the following reconciliation of reported Non-GAAP financial measures to comparable financial measures reported on a GAAP basis. UAL believes that excluding fuel costs from certain measures is useful to investors because it provides an additional measure of management’s performance excluding the effects of a significant cost item over which management has limited influence. UAL believes that adjusting for special charges is useful to investors because they are non-recurring charges not indicative of UAL’s ongoing performance. UAL also believes that excluding third-party business expenses, such as maintenance, ground handling and catering services for third parties, fuel sales and non-air mileage redemptions, provides more meaningful disclosure because these expenses are not directly related to UAL’s core business. In addition, UAL believes that excluding non-cash (gains)/losses on fuel hedges from nonoperating expense is useful because it allows investors to better understand the impact of settled hedges on a given period’s results.
