The Boeing 777X is the latest series of the long-range, wide-body, twin-engine jetliners in the Boeing 777 family from Boeing Commercial Airplanes. The changes for 777X include General Electric GE9X engines, composite wings with folding wingtips , greater cabin width and seating capacity, and technologies from the Boeing 787 .
The new Boeing 777X features a shorter and simpler folding wingtip than was planned for the earlier Boeing 777, which will provide an extra 7 metres (23 ft) of total wingspan in flight, while allowing the airplane to fit inside the same airport gates as the 777-200LR/777-300ER.
The never-before-seen technology has several advantages, but the idea stemmed from airport-gate space limitations and the 777X's huge wingspan. The folding wing tips on Boeing's massive new 777X ...
Wingtip devices help prevent the flow around the wingtip of higher pressure air under the wing flowing to the lower pressure surface on top at the wingtip, which results in a vortex caused by the forward motion of the aircraft. Winglets also reduce the lift-induced drag caused by wingtip vortices and improve lift-to-drag ratio.
The 777X would provide airlines with another version of the plane, in addition to the popular but aging 777-300ER. Boeing employees build 777 aircrafts in June 2024. - Jennifer Buchanan/AFP/Getty ...
The first member of the 777X family was projected to enter service in 2020 at the time of the program announcement. The roll-out of the prototype 777X, a 777-9 model, occurred on March 13, 2019.

The Boeing 777X is better for United's central hubs. The Boeing 777X is intended to replace the company's 747 model and the Airbus A380 as a more efficient, high-capacity long-haul jetliner.
