Welcome to FlyerTalk.
As it says in the Announcement at the top of the page, Announcement: PLEASE READ BEFORE POSTING: NEW AMERICAN / AA and US Pre-Merger FORUM STRUCTURE, AA and US operate as separate airlines at the moment. The Consolidated forum is for those issues that are about merged operations, current and future. We've moved your query to the proper forum.
