The airline's on-time performance improved in October as negotiations progressed and after the company threated to take the union to court for what it called an illegal job action.
In a message to its members Friday, the union said its board of directors will now vote to on whether or not to pass on the agreement to the membership for ratification. That is likely to happen since the board has already shown support for the latest proposal by voting 13-to-2 on a related matter.
The board's next vote could happen within a week. The members then get two weeks to review the contract language before voting.
The union said it will provide details shortly.
American, based in Fort Worth, Texas, said it is pleased to have the agreement in principle and worked hard “to structure an agreement that addresses the priorities identified as most important to our pilots, while staying within the economic framework” it faces in its bankruptcy.
