Introductions of A320:

The Airbus A320 family is a series of narrow-body airliners developed and produced by Airbus. The A320 was launched in March 1984, first flew on 22 February 1987, and was introduced in April 1988 by Air France. The first member of the family was followed by the longer A321 (first delivered in January 1994), the shorter A319 (April 1996), and the even shorter A318 (July 2003). Final assembly takes place in Toulouse in France; Hamburg in Germany; Tianjin in China since 2009; and Mobile, Alabama in the United States since April 2016.

The twinjet has a six-abreast cross-section and came with either CFM56 or IAE V2500 turbofan engines, except the CFM56/PW6000 powered A318. The family pioneered the use of digital fly-by-wire and side-stick flight controls in airliners. Variants offer maximum take-off weights from 68 to 93.5 tonnes (150,000 to 206,000 lb), to cover a 5,740–6,940 kilometres; 3,570–4,320 miles (3,100–3,750 nmi) range. The 31.4 m (103 ft) long A318 typically accommodates 107 to 132 passengers. The 124-156 seat A319 is 33.8 m (111 ft) long. The A320 is 37.6 m (123 ft) long and can accommodate 150 to 186 passengers. The 44.5 m (146 ft) A321 offers 185 to 230 seats. The Airbus Corporate Jets are business jet versions.

In December 2010, Airbus announced the re-engined A320neo (new engine option), which entered service with Lufthansa in January 2016. With more efficient turbofans and improvements including sharklets, it offers up to 15% better fuel economy. Earlier A320s are now called A320ceo (current engine option).

American Airlines is the largest A320 operator with 469 aircraft in its fleet. In October 2019, the A320 family surpassed the Boeing 737 to become the highest-selling airliner. As of July 2023, a total of 17,737 A320s had been ordered and 10,997 delivered, of which 10,256 aircraft were in service with more than 340 operators. The global A320 fleet had completed more than 164 million flights over 303 million block hours since its entry into service. The A320ceo initially competed with the 737 Classic and the MD-80, then their successors, the 737 Next Generation and the MD-90, while the 737 MAX is Boeing's response to the A320neo.
