The A350 is the first Airbus aircraft largely made of carbon fibre reinforced polymer. It has a new fuselage designed around a nine-abreast economy cross-section, up from the eight-abreast A330/A340. It has a common type rating with the A330. The airliner has two variants: the A350-900 typically carries 300 to 350 passengers over a 15,000-kilometre (8,100-nautical-mile) range, has a 280-tonne (617,300-pound) maximum take-off weight (MTOW); the longer A350-1000 accommodates 350 to 410 passengers, has a maximum range of 16,100 km (8,700 nmi) and a 319 t (703,200 lb) MTOW.
On 15 January 2015, the initial A350-900 entered service with Qatar Airways, followed by the A350-1000 on 24 February 2018 with the same launch customer. Singapore Airlines is currently the largest operator with 56 airplanes in its fleet. As of July 2021, A350 orders stood at 915 aircraft, of which 438 had been delivered and all were in service with 39 operators. It succeeds the A340 and is positioned to compete against Boeing's large long-haul twinjets: the 787, the 777, and its successor, the 777X.
