American Airlines is starting scheduled flights with the first of its 100 new Airbus A321neo aircraft. The aircraft are equipped with a cabin interior that features larger overhead luggage bins that increase carry-on bag capacity. American is the launch customer for the Airspace XL bins, which provide about 40 percent more overhead storage space for passengers on board the 196-seat planes. The carrier also plans to retrofit its entire service fleet of earlier A321 models – more than 200 aircraft – with the cabin features included on the A321neos.The bins accommodate larger luggage, allowing standard roll-on bags to be loaded on their sides instead of being inserted flat. This creates room for up to four bags in each bin instead of the current three. The bins will significantly reduce the number of passenger bags checked at the gate and sent to the cargo hold.
