Airbus A321
The Airbus A321 is the largest member of the A320 family, introduced by Airbus SAS in 1994 and entering service in 1995 with Air France. Developed as a stretched‑up version of the A320, the A321 offers a fuselage length of 44.5 meters and a typical seating capacity of 185 to 236 passengers in a single‑aisle layout, depending on cabin configuration. Powered by either CFM International CFM56 or the newer Pratt & Whitney PW1100G‑JM geared turbofan, the aircraft delivers a range of up to 4,000 nautical miles, allowing it to serve both short‑haul European routes and medium‑range transcontinental flights. Key technological features include fly‑by‑wire flight controls, a glass cockpit shared across the family, and the option for winglet or Sharklet wingtip devices that improve fuel efficiency by up to 4 percent. The A321 has become a cornerstone for airlines seeking to maximize capacity without transitioning to wide‑body types, and its later A321neo and A321LR/A321XLR variants have extended its relevance by offering superior fuel burn, lower operating costs, and ultra‑long‑range capability. As a result, the A321 family has reshaped market dynamics, supporting fleet commonality, reducing route economics, and cementing Airbus’s competitive position in the single‑aisle segment.
