Status

The Boeing 777-9 is the largest variant of the 777X family, a next-generation wide-body twin-engine airliner developed by Boeing. It features a composite folding wingtip design, allowing a wingspan of approximately 71.8 meters to fold down to around 64.8 meters for gate compatibility. The aircraft incorporates advanced GE9X engines and a new composite wing for improved fuel efficiency. Originally intended to enter service around 2020, the 777-9 has faced significant delays due to engine certification issues, the COVID-19 pandemic's impact on aviation demand, and additional regulatory scrutiny following the 737 MAX crises. As of the mid-2020s, the aircraft was still completing certification with the FAA. The 777-9 is designed to carry around 426 passengers in a typical two-class configuration over ranges of approximately 13,500 km. It is intended to replace aging 747s and A380s at major carriers worldwide, offering lower operating costs per seat than comparable widebody aircraft.

Notable operators

Launch customers and major orders include Emirates, Lufthansa, All Nippon Airways, Singapore Airlines, and Qatar Airways, though none had placed the aircraft into revenue service as of early 2025.

Encyclopaedia

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.
