The Airbus A321neo is the largest member of the new Airbus A320neo family of aircraft. The liner is a thorough modernization of the popular Airbus A321 passenger plane with new generation engines and larger wing tips (sharklets). The A321neo is the most fuel-efficient narrow-body aircraft in its class. The redesigned cabin has been designed to provide greater comfort and is very popular with passengers. It will comfortably accommodate 180 to 220 passengers in a typical two-class cabin layout and up to 244 passengers in a denser layout. Airbus A321neo has been mass-produced and operated by airlines since April 2017.
