United CEO Jeff Smisek told the Financial Times that although a consolidation could adversely affect the alliance that United and US Airways both belong to, he would not stand in the way of a merger between the two.
‘The three biggest U.S. airlines each anchor a separate worldwide airline partnership, with American in oneworld and US Airways and United both in the Star Alliance. US Airways has been widely expected to leave Star for oneworld if it merges with American.’
These airline partnerships allow customers to buy tickets through one airline and travel on all of the airlines that are part of that group.
American Airlines filed for bankruptcy in November of last year and is in the process of reorganizing but cutting billions from its costs.
