American Airlines Chief Executive Officer Tom Horton said “there’s a way” to reach a settlement with U.S. antitrust regulators seeking to block the merger of the AMR Corp. unit with US Airways Group Inc., Bloomberg News reported yesterday. “If there’s a reasonable settlement, I think it’s better for both sides” than going to trial, Horton said. The suit is set for a Nov. 25 trial. A merger between Fort Worth, Texas-based American and US Airways would create the world’s largest airline. The all-stock merger is now valued at $16.6 billion, based on US Airways’ share price and its stake in the new American, which is counting on the deal as its exit strategy from bankruptcy.
