DALLAS (AP) American Airlines ground workers split over the company's final contract offer that would spare some jobs targeted for elimination.

The Transport Workers Union said Tuesday that five work groups accepted the company's offer but the biggest, aircraft mechanics, rejected it.

Pilots, flight attendants and the TWU have already thrown their support to a bid by US Airways to take over American and create a bigger combined airline.

AMR Corp.'s American Airlines is trying to throw out other union contracts to cut costs as it goes through bankruptcy protection. A hearing on that move continued Tuesday in federal district court in New York.
