American Airlines today operates the largest fleet of any airline. This is a mixed Boeing and Airbus narrowbody fleet and an all Boeing widebody fleet. Since the pandemic hit, it has been noticeably simplified. Looking back over its history, though, it has a much more mixed fleet. This includes Boeing and Airbus as well as several others – McDonnel Douglas, British Aerospace, Fokker, and Embraer.
American Airlines is one of the oldest continuously operating airlines in the world. Several airlines came together in the 1930s to operate under a single brand – with the oldest of these (American Airways) tracing its origins back to 1927.
