American Airlines parent AMR Corp. says it lost $82 million in August, the tail end of the key summer travel season.
Fort Worth-based AMR offered details Thursday in a regulatory filing.
The company says it would have earned $55 million if not for bankruptcy expenses of $86 million and other special items.
Revenue for August was $2.19 billion, down from $2.33 billion in July.
The figures don't include results for the rash of delayed and canceled flights that began in early September after American canceled a contract with its union pilots and set pay and working terms.
On Thursday, the company told union officials to order pilots to stop what AMR considers delaying tactics such as asking for maintenance checks just before takeoff. The president of the Allied Pilots Association then sent a letter to pilots instructing them to end any unsanctioned job actions.
