The Airbus A310’s maximum typical passenger capacity in a two-class layout is 220 passengers.
The A310 is a shortened derivative of the A300 and was developed for airlines needing a smaller wide-body aircraft. Airbus designed it with a shorter fuselage, a revised wing, and a two-person flight deck. The type first flew in 1982 and entered airline service in 1983.
Capacity varied according to the exact model and cabin arrangement. Published figures commonly list up to 220 passengers in a typical two-class configuration, while high-density layouts could accommodate more. That distinction is why capacity figures for the A310 are sometimes reported differently.
The A310 also became significant outside passenger service. Several examples were converted or delivered for cargo, military transport, tanker, and government roles. Its design helped establish the smaller wide-body segment that later included aircraft such as the A330-200.
