About the Airbus 350-900

The Airbus A350-900 represents the European manufacturer's answer to Boeing's 787 Dreamliner, entering service in 2015 as the first Airbus widebody designed from scratch in over two decades. Built with a carbon-fiber-reinforced polymer fuselage and wings (over 50 percent composite materials by weight), the A350 delivers exceptional fuel efficiency and range, capable of flying up to 8,100 nautical miles nonstop while carrying 325 passengers in typical three-class configuration. Powered by Rolls-Royce Trent XWB engines, the world's most efficient large turbofan at entry into service, the type cruises at Mach 0.85 and operates comfortably at altitudes up to 43,100 feet.

The flight deck features Airbus's latest-generation avionics with six large LCD displays and full fly-by-wire controls, while the cabin offers wider seats, larger windows, and lower cabin altitude than previous-generation widebodies. Qatar Airways launched the type into commercial service on the Doha-Frankfurt route in January 2015, and the A350-900 quickly became the backbone of long-haul fleets worldwide, competing directly with the 787-9 and replacing aging 777-200ERs and A340s. Its combination of range, efficiency, and passenger comfort has made it particularly popular on ultra-long-haul routes across the Pacific and to the Middle East.

The type has proven remarkably reliable in service, with dispatch reliability exceeding 99 percent across most operators. SkyMeter has tracked flights across airframes and operators on routes, with the largest observed operator.
