A lot has happened since American and US Airways first announced their merger in February 2013, which has made them the world’s largest airline. If you were loyal to either airline, you’re likely familiar with just about every major milestone of the merger, given that it impacted the passenger experience.
These steps included the merger of the AAdvantage and Dividend Miles programs, the two airlines getting a single operating certificate with the FAA, the two airlines getting on a single reservations system, employees of both airlines getting the same uniforms, etc.
Even wth all of this alignment, as a customer you can still quite easily tell whether you’re on a legacy American or legacy US Airways plane. Does the plane not have any power ports or Main Cabin Extra? You’re probably on a legacy US Airways plane. Are you not getting a pre-departure beverage? You’re probably on a legacy American plane. 😉
