EI-DEC A320-214 (MAN) Aer Lingus (2) - Carl Daniels Photography

The A320 single-aisle jetliner family (composed of the A318, A319, A320 and A321) is the undisputed best-selling aircraft product line of all time. It is used in a full range of services from very short-haul airline routes to intercontinental segments, on operations from challenging in-city airports to high-altitude airfields and an Antarctic ice runway, and on VVIP and government missions with the most discerning passengers.
