Status

In production, awaiting certification

The Boeing 777-9 is the largest and most advanced variant of the 777X family, a next-generation wide-body airliner developed by Boeing. It features a composite folding wingtip system, the largest wingspan of any Boeing commercial aircraft, and new GE9X engines — the most powerful commercial jet engines ever built. The aircraft is designed to carry around 426 passengers in a typical two-class configuration over ultra-long ranges. Development has faced significant delays due to structural certification challenges, engine issues, and broader Boeing quality and regulatory scrutiny. Originally planned to enter service around 2020, the 777-9 remained uncertified as of mid-2025, with Emirates, Lufthansa, and Qatar Airways among the largest customers awaiting delivery. The 777-9 incorporates advanced aerodynamics, a next-generation composite wing, and cabin innovations shared with the 787 Dreamliner, including larger windows and improved cabin pressure. It is intended to replace aging 747-400s and early 777-200/300 fleets at major international carriers.

Encyclopaedia

The Boeing 777X is an American long-range, wide-body, twin-engine airliner built by Boeing Commercial Airplanes, undergoing flight testing as of 2026. A substantial development from the original Boeing 777, changes for the 777X include General Electric GE9X engines, composite wings with folding wingtips, greater cabin width and seating capacity, and technologies from the Boeing 787 Dreamliner. The 777X program was launched in November 2013 to develop two variants: the 777-8 and the 777-9. The 777-8 provides seating for 350 to 425 passengers and has a range of 9,500 nautical miles [nmi], while the 777-9 has seating for 375 to 450 passengers and a range of 8,000 nmi.
