The merger of American Airlines and US Airways created the world's biggest airline.
The merged carrier will be the world's biggest and will keep the American Airlines name, but it will be run by US Airways CEO Doug Parker. American's CEO, Tom Horton, will serve as chairman of the new company until mid-2014. It will be based in Fort Worth, Texas.
The merger will bring American Airlines to an estimated market valuation of US$11 billion.
Before any merger goes ahead, it needs approval from competition regulators and a US bankruptcy court.
If the deal is approved by AMR's bankruptcy judge and antitrust regulators, the new American will have more than 900 planes, 3,200 daily flights and about 95,000 employees, not counting regional affiliates. It will be slightly bigger than United Airlines by passenger traffic.
American's presence will grow in key East Coast markets including New York's LaGuardia Airport and Washington's Reagan National Airport. The merger will add US Airways hubs in Charlotte, Philadelphia and Phoenix to American's in Dallas-Fort Worth, Chicago, Miami, New York and Los Angeles.US Airways will boost American's service to Europe and the Latin America-Caribbean market but wouldn't fix American's weakness on routes to Asia.
