Airbus A320 family operator American Airlines
Variants
The baseline A320 has given rise to a family of aircraft which share a common design but with passenger capacity ranges from 100, on the A318, to 220, on the A321. They compete with the 737, 757, and 717. Because the four variants share the same flight deck, all have the same pilot type rating. Today all variants are available as corporate jets. An A319 variant known as A319LR is also developed. Military versions like A319 MPA also exists. American Airlines is the largest airline operator of the A320 family of aircraft with 392 aircraft in service as of 30 September 2017.Technically, the name "A320" only refers to the original mid-sized aircraft, but it is often informally used to indicate any of the A318/A319/A320/A321 family. All variants are able to be ETOPS (Extended-range Twin-engine Operational Performance Standards) certified for 180 minutes since 2004 (EASA) and 2006 (FAA). With launch of the new Airbus A320neo project, the previous members of the Airbus A320 family received the "current engine option" or "CEO" name.Operators
