If that statement is true it could become the QATAR/EMIRATES/ETHIAD killer. Basically means you can fly anywhere in the world non-stop. Not what the ME Carriers will want to be hearing.
There's a difference between doing flights like that and doing them profitably.
The 777-200LR comes damn close and is capable of routes no other aircraft can do non-stop, but has probably been the least successful version commercially.
To get to extreme ranges like that, the extra fuel burn needed just to carry the fuel become prohibitive, and almost always limits payload.- you actually save a lot of fuel on a trip basis by doing a tech stop and can carry as much as the aircraft can hold.
PLUS you are restricted to one city pair. The ME carriers are doing so well because the rergion works as a hub, conecting almost everywhere to almost everywhere else with one stop.
