Timeline: American, U.S. Airways merger

Updated Dec. 9, 2013

American Airlines has emerged from bankruptcy protection and US Airways culminated its long pursuit of a merger partner after the two completed their deal Monday to create the world’s biggest airline.

The merger survived a challenge from the government and criticism from consumer groups, who fear it will lead to higher prices. It’s the latest in a series of mergers that will leave four airlines controlling more than 80 percent of the U.S. air-travel market and with more power than ever to limit seats and boost profits.
