The Airbus A321neo is a single-aisle airliner created by Airbus. The A321neo (neo being Greek for new, as well as an acronym for new engine option) is developed from the Airbus A321 & Airbus A320neo family. It is the longest stretched fuselage of Airbus's A320 series, and the newest version of the A321, with the original A321ceo debuting in 1994 with Lufthansa. It typically seats 180 to 220 passengers in a two-class configuration, with up to 244 passengers in a high-density arrangement. The A321neo was seen as a direct response to the Boeing 757 & 737 MAX, which debuted one year after the introduction of the A321neo.
