In 2005, Mesa's codeshare agreement with US Airways was not reaffirmed in bankruptcy court, and Mesa began transitioning the aircraft to other codeshares. Twenty-six ERJ aircraft were transitioned to Freedom Airlines, and the CRJ and remaining ERJs were transferred to Mesa's United Express operation. However, following the America West Airlines merger later that year, the Mesa contract for America West Express was retained and expanded to include non-former America West Express routes. All US Airways Express flying was converted to American Eagle on October 17, 2015, when the merger between American and US Airways was completed.
