The Airbus A350 XWB is a family of long-range, wide-body jet airliners under development by European aircraft manufacturer Airbus. The A350 will be the first Airbus with both fuselage and wing structures made primarily of carbon fibre-reinforced polymer. It will carry 250 to 350 passengers in three-class seating, depending on variant. The A350 was originally conceived in 2004 as a widely new design, but with a fuselage based on the A330. This was rejected by some prospective customers.
