About the 777X

The first flight was conducted by N779XW, a 777-9 variant. Boeing will build two versions, the 777-8 and 777-9. The larger 777-9 is designed to accommodate up to 426 passengers in a two-class configuration with a range of 13,500 km (7,285 nmi). The slightly smaller 777-8 will carry up to 326 passengers in a two-class configuration, but with an increased range of 16,170 km (8,730 nmi).

The 777X’s wingspan is 8 meters longer than the 777-300ER, but Boeing designed it to fit gates capable of handling existing 777s by adding folding wingtips.

The 777X also features the world’s largest jet engine, the General Electric GE9X. Developed specifically for the 777X, the GE9X builds on the GE90 engine that powers current models of the 777.
