What is the largest Airbus A330?

As the A330neo Family's largest member, the A330-900 retains the fuselage length of Airbus' A330-300 variant to accommodate between 260 and 300 seats in a typical three-class layout, or up to 460 in economy class.



The largest member of the A330 family is the Airbus A330-900 (A330neo). Measuring 63.66 meters (208 feet 10 inches) in length, it is several meters longer than its predecessor, the A330-200. In 2026, this aircraft is the "workhorse" of many international fleets, offering a typical seating capacity of 280 to 300 passengers in a three-class layout, or up to 460 in a high-density all-economy configuration. It features a massive wingspan of 64 meters, utilizing advanced "Sharklets" for better fuel efficiency. Before the "neo" (New Engine Option) generation, the A330-300 held the title for size, but the -900 has surpassed it in both length and technological capability. The A330-900 is favored in 2026 for its "Airspace by Airbus" cabin, which provides larger overhead bins, updated LED mood lighting, and the quietest interior in its category. For travelers, this means a significantly more comfortable long-haul experience compared to the older, smaller A330-200 models still in service.
