American Airlines, US Air merger approved From:AFP March 28, 2013 9:56AM A US bankruptcy court judge has approved the merger of American Airlines and US Airways, which will create the country's largest airline, a spokesman for American's corporate parent AMR Corp says. But the judge left undecided the $US19.9 million ($19m) payout planned for AMR chief executive Tom Horton, who will lose his job in the merger. The judge "has approved moving on with the merger", spokesman Casey Norton said. However, as for Mr Horton's severance, "he wants to consider it at a later time", Mr Norton said. Some American Airlines creditors have reportedly raised objections to the payout as the company emerges from bankruptcy restructuring. The combined airline, to keep the American Airlines name, is to be led by current US Airways chief executive Doug Parker.
