The Airbus A321-200neo (New Engine Option), is a narrow-body airliner, second generation, successor to the original A321-200. The A321-200neo boasts new engines, amongst other improvements, and continues the popularity of it's predecessor. It's main rival is the Boeing 737/737 MAX and is starting to compete with the Boeing 757 as well. The A321-200neo is almost identical in look and design as the 'ceo' option with the exception of the now standard wiglets and the look of the engine nacelles. The Airbus A321-200neo variant is comprised of three sub-variants; the standard A321neo (A321-200N), the A321neoLR (Long Range - A321-200NX), and the A321neoXLR (eXtra Long Range). The A321-200neo is in production with a large order backlog. It can serve short, medium, and long haul routes that have medium to high demand and can easily be interchanged on routes that are currently served by A320-200ceo aircraft or other aircraft in the 'ceo/neo' family. With this flexibility and improvements with the new design, airlines are quickly turning to the A321-200neo for the future of their narrow-body fleet.
