Airbus A350: The Composite Widebody Built on Decades of Safety Lessons

The Airbus A350 is a long-range widebody with two engines, launched in 2006 as an all-new design. The first A350-900 flew on June 14, 2013, and Qatar Airways flew the type's first passenger service on January 15, 2015. The stretched A350-1000 first flew on November 24, 2016, and joined Qatar Airways in February 2018.

Its airframe is what sets it apart. More than 70 percent of it is advanced material, including 53 percent composites, 14 percent titanium and modern aluminum alloys, a mix Airbus says saves weight and maintenance. Together with new engines and aerodynamics, Airbus says, that brings a 25 percent saving in fuel burn and CO2 over previous-generation rivals.

An A350-900 is 66.8 meters (219 feet) long and an A350-1000 is 73.8 meters (242 feet), on a shared 64.75-meter (212-foot) wingspan. Airbus quotes 300 to 350 seats in three classes for the -900 and 350 to 410 for the -1000, with up to 480 in the densest layout. A freighter version, the A350F, is designed to carry up to 111 tonnes.

Quick facts

Why the Airbus A350 matters

Every modern airliner, the A350 included, is built under rules shaped by decades of accident investigations. Its cabin has smoke detectors in the lavatories, fire-resistant seat cushions and floor lighting that leads to the exits. A new design must also show, in full-size fatigue tests, that widespread cracking won't appear. How safe flying is tells the longer story of how those lessons were learned.

The A350 also shows how far long-haul comfort has come. Its composite fuselage lets the cabin be pressurized to the equivalent of 6,000 feet, where an aluminum airliner is held at about 8,000; why planes fly so high explains what cabin altitude means. HEPA filters clean the air, which is fully renewed about every two to three minutes. Airbus says the cabin is 5 decibels quieter than competing aircraft, and up to 9 decibels quieter toward the front.

Airlines have bought it in large numbers: as of October 2026, Airbus listed more than 1,500 orders and 700 deliveries. Its closest rivals are Boeing's 787 Dreamliner and 777. Boeing vs Airbus shows the quickest way to pick out an A350: the black band painted around its cockpit windows.

Notable facts

• Its Rolls-Royce Trent XWB engines are rated at 84,000 pounds of takeoff thrust on the A350-900 and 97,000 on the A350-1000.
• Europe's aviation safety agency approved the A350-900's design on September 30, 2014, and the FAA followed on November 12. Qatar Airways took the first delivery on December 22, 2014.
• The A350-900ULR, which entered service with Singapore Airlines on October 11, 2018, can fly 9,700 nautical miles nonstop. In January 2024, Airbus called it the longest-range airliner in service.
• The A350-900 and A350-1000 share 95 percent of their part numbers, even though the -1000 is about 7 meters longer.
• Airbus says the A350's cabin is 221 inches (5.6 meters) wide, 6 inches wider than the cabin of the 787.
