Asking because during the winter AA had at times had to do fuel stops on DEL-JFK on their 77Ws after they stopped flying through Russian airspace.
CX hasn’t flown the 77W to JFK, I think, on the current routing that avoids Russian airspace- all current flights are on A350s.
CX is currently taking a 8,800 mi route from JFK-HKG. Is that within range for a 77W or a 772?
I don't think it can. That's probably only for the B787 or A350.
