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.



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.
