The Airbus A330-300 is the stretched twin-engine variant of the A330 family and Airbus's workhorse widebody for most of the 2000s and 2010s. It entered service with Air Inter in 1994 and became a standard aircraft for European flag carriers on transatlantic and Middle Eastern routes. The A330-300 seats 277 to 335 passengers in typical configurations and has a range of around 6,350 nautical miles. The aircraft offered an attractive operating cost per seat on medium-to-long-haul routes, particularly for airlines that did not need the range of a 777 or the capacity of a 747. The A330-900neo has since taken over the production line, but the ceo A330-300 remains in service with hundreds of aircraft worldwide. Turkish Airlines, Cathay Pacific, Qantas, and Delta all operated large A330-300 fleets at various times.
