Boeing 777X

The Boeing 777X is the latest development of the company's wildly successful 777 family of airliners. Under development, the 777X is expected to replace not only existing versions of the 777 but also Boeing's iconic 747 jumbo jet.

The 777X is available in two versions ranging from 350 to 425 seats and will be powered by General Electric GE9X engines. According to industry analysts, the 777X is expected to deliver unit costs lower than that of the Airbus A380 superjumbo.

Through April, Boeing has 306 orders for the 777X, which are expected to enter service in late 2019.
