Developed from the 777-300ER, the three-family 777X series incorporates General Electric GE9X engines and a high-aspect composite wing design to deliver an aircraft targeted at approximately 12% lower fuel consumption than the Airbus A350-1000.

First to enter service in 2023 is the 400-plus seat 777-9 with a fuselage stretch of 9 ft. overall and 20% per seat fuel burn improvement over the 365-passenger 777-300ER. The shorter 777-8, which shares the same fuselage length as the recently launched 777-8F freighter, will carry similar passenger loads as the 777-300ER, but with a 13% fuel burn improvement while flying more than 1,000 nm farther.

Launched in 2013, the 777-9 first flew in January 2020, and is undergoing flight tests. The 777-8F freighter, which will carry 31 freight pallets on the main deck, plus existing space for 13 pallets and additional bulk cargo, or 5,995 cu. ft., in the lower holds, is due to enter service in 2027. The debut of the 777-8, which Boeing delayed to focus on development of the 777-9, is now expected towards the end of the decade.
