Exhibit 99.1

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.
