United CCO also confirmed that the updated IGW will allow Chicago to Tokyo will full cargo and passengers even with pacific winds. Same applies to Auckland to Los Angeles/San fracisco.
The IGW increases the MTOW by 6 tonnes and includes fuel software management improvements.
Interesting, thanks for sharing. It'd be cool to know how an IGW version will perform on hot&high destinations, and how much further will BA shrink the envelope. I have no certain proof of that, but back in the day friends in the relevant departments were saying that BA had no planes with which to fly LHR-BOG without punitive restrictions, and yet here is Avianca going back and forth with the 787...
Given BA already generally has a very premium heavy config compared to most carriers. I don’t doubt the 78X in its IGW form can do HND and I think it can do GIG. But that’s not it’s focus. It’s focus is the 77E. And they don’t fly that far. 78X can cover all of it.
Now will BA replace all the 77Es with 78X? I highly doubt it. And I generally agree with 13901 it will be a mix.

for the RR 777s that’s between the 789 and 359. But again, 789 might have the inroad here because whilst BA have the 35K, the 359 is still a bit different with different engines, and parts.
789 and 78X share all the same parts, including engines. 788, 789 and 78X all share the same engines and engines can be switched out between the two. These are some of the things Boeing will be saying.
but I would imagine IAG might want to diversify. But they might not like United that’s gone all in 787s.
I don’t know which way BA will go but IMO fhe 78X makes it way in there. The way BA have set it up, it’s pretty obvious the plans they’ve got for it
I agree on the GE-motorised 777s being replaced by the 78X. Don't think it's going to happen before the mid-to-late 2020s given that they've just been refurbished, but I'm surprised about your call for the 789 as a possible RR 77Es replacement, I always considered the 789 to be a bit too 'small' to replace the 332-seater LGW 77Es. The densest around I think is Norse's, with some 340 seats but without lie-flat seats.
