AMR Corp.'s American Airlines won court approval to throw out its labor agreement with pilots, capping the airline's campaign to force cost cuts on the lone union it could not reach a deal with on concessions, Bloomberg News reported today. Bankruptcy Judge Sean Lane yesterday granted American's request to reject the pilots' contract, saying that proposed changes to the agreement are necessary for the airline's restructuring. The Allied Pilots Association had argued that American's demand for $370 million in cost savings from the pilots "greatly exceeds" the amount required to reorganize.
