How long and how fast can the Boeing 777X fly?
With and without passengers and cargo.
This requires the Boeing 777-8X and Boeing 777-9X.

Topping-off fuel tanks in ALL airplanes reduces passenger (or payload) capacity -
A 777-8X will be he same - They might have to reduce number of passengers for long flights -
I do not know the 777-8X - but will be same as any other airplane -
With full passenger, cargo or payload, they will have to reduce maximum flight range -
As far as the speed goes, they will probably be cruising at Mach .84, light or heavy -
Giving you an example for a 747...
With a 747 and 380 passengers, we can fly 13 hours long sectors legs -
But fully loaded 747 cargo (carrying 120 tons freight) barely can carry fuel for 7 hours flight -Source(s): Retired airline pilot
