Pilots for AMR Corp.'s American Airlines asked a U.S. bankruptcy judge to suspend his order allowing the carrier to throw out their labor contract and impose cost cuts while their appeal is considered, Bloomberg News reported on Saturday. The decision by Bankruptcy Judge Sean Lane allowing AMR to reject the contract will cause "irreparable harm" to pilots, the Allied Pilots Association said in a court filing on Friday. American won Judge Lane’s approval on Sept. 4 to impose work rule and other changes as it restructures after pilots rejected a final contract offer. The union has appealed the decision to U.S. District Court in Manhattan and is asking Judge Lane to stay his order while the appeal is considered.
