About the Airbus A350-1000 XWB

The Airbus A350-1000 is the stretched, ultra-long-range variant of the A350 XWB family, designed to compete directly with the Boeing 777-300ER while delivering superior fuel efficiency and passenger comfort. Launched in 2010 and entering service with Qatar Airways in 2018, the -1000 extends the fuselage by 7 meters over the baseline A350-900, accommodating 350-410 passengers in typical three-class layouts. Its carbon-fiber-reinforced polymer airframe—comprising 53% of the structure—and Rolls-Royce Trent XWB-97 engines enable a maximum range of 8,700 nautical miles, making it ideal for ultra-long-haul routes like Doha to Auckland or Singapore to New York.

The type holds the distinction of being the largest twin-engine widebody Airbus has ever built, with a maximum takeoff weight of 693,900 pounds. Its advanced aerodynamics, including distinctive curved wingtips spanning 212 feet, contribute to a 25% improvement in fuel burn per seat compared to the aircraft it replaces. The A350-1000 cruises at Mach 0.85 with a maximum operating speed of Mach 0.89, and its 43,100-foot certified ceiling matches the highest altitudes flown by commercial widebodies.

The spacious cabin features larger windows, LED mood lighting, and lower cabin altitude (6,000 feet at cruise) for reduced passenger fatigue on marathon sectors. SkyMeter has tracked flights across airframes and operators on routes, with the largest observed operator.
