American's economy plus product (not to be confused with premium economy), Main Cabin Extra, is available on most of the mainline fleet and American Eagle regional aircraft with more than 50 seats. Exceptions include a majority of former US Airways aircraft (as of May 2014), US Airways Express regional aircraft, and a handful of 777-200ERs that have yet to be retrofitted. Seats range from 17.2–19.5 inches (44–47 cm) in width and have 34–38 inches (86–97 cm) of pitch, which is 5–6 more inches of pitch offered in regular economy seating. American retained Main Cabin Extra when the new Premium Economy product entered service in late 2016.
On January 17, 2013, American unveiled a new livery. Before then, American had been the only major U.S. airline to leave most of its aircraft surfaces unpainted. This was because C. R. Smith hated painted aircraft, and refused to use any liveries that involved painting the entire plane. Robert "Bob" Crandall later justified the distinctive natural metal finish by noting that less paint reduced the aircraft's weight, thus saving on fuel costs.
