This is the Boeing 777-9X, soon to be called the 777-9 (or maybe 777-900). It has almost the same pax/cargo capacity as the 747-400, but with way lower fuel burn and nearly 1,000 nautical miles more range. And the order book for the 777-9X is already 243 planes.
Nice looking jet.
The 777 is the most comfortable plane on which I have ever flown (in coach).
Triple 7 is sweetest airliner flying.....flew in cockpit of a BA 777 from Heathrow to Dulles in 2000............
But then, I’ve not flown in the 787......
