Engines

Two GE9X-102B1 high-bypass turbofan engines

Status

In development

The Boeing 777-8 is the smaller of two variants in the 777X family, the other being the 777-9. It is designed to replace the 777-200LR and 777-200ER, offering significantly improved fuel efficiency through the use of composite folding wingtips, a new carbon-fiber composite wing, and GE9X high-bypass turbofan engines. The aircraft is intended to carry approximately 384 passengers in a typical two-class configuration over ranges exceeding 16,000 kilometres, making it one of the longest-range commercial airliners in development. Boeing has faced repeated delays in the broader 777X program due to technical challenges, regulatory hurdles, and certification issues. As of the mid-2020s, the 777-8 has not yet entered commercial service, with its entry into service trailing behind the larger 777-9 variant. Airlines such as Emirates and Lufthansa have placed orders for the type, anticipating its eventual certification by the FAA.

Notable operators

Emirates, Lufthansa, and Qatar Airways are among the primary customers with orders for the 777-8.
