US Airways has yet to set a date for leaving the Star Alliance, as it awaits regulatory approval for its merger with American Airlines.
Doug Parker, chairman and chief executive of the Tempe, Arizona-based carrier, says that there is no timeline yet for US Airways' departure from the alliance, at a press conference in Dallas today.
"We have to work it out with our Star partners," he says.
US Airways will become part of the Oneworld alliance as part of its merger with American. The Fort Worth-based carrier is a founding member of the alliance.
"Our member US Airways proposes to merge with American Airlines," wrote Star on its Facebook page. "The merger proposal will now be examined by the regulatory authorities. In the meantime, US Airways remains a full Star Alliance member and will continue to offer the defined benefits to Star Alliance customers."
American and US Airways estimate that Oneworld will include about 34% of global available seat miles (ASMs) following the combination. This is up from about 26% pre-merger.
Star's share of global ASMs is expected to decrease to 36% from 45%, according to the airlines' analysis.
"We think Oneworld is the best alliance," says Tom Horton, chairman, president and chief executive of American parent AMR, today.
International Airlines Group (IAG) chief executive Willie Walsh said in July 2012 that he saw "merit" in the combination of American and US Airways. He added that the combined company would likely be good for IAG-owned British Airways and for Oneworld.
