There will be two models — the longer-range 777-8, capable of flying just over 10,000 miles without a stop, and the larger 777-9, with seating for up to 425, depending on the configuration.

So far, a handful of airlines have signed on to operate the 777X, including the seven carriers below, plus British Airways, which just confirmed plans to order 18 Boeing 777-9s to replace its aging 747-400 fleet.

The first 777X will be used for initial flight testing beginning later this year, with the wide-body jet expected to enter passenger service sometime in 2020.
