I think I have flown every aircraft type in the BA fleet which they have operated since the mid 80’s. I’ve lost count of the number of trips in pre-cradle club, cradle, CW, NCW, pre-flat F, old F, NF, Concorde, etc etc.
That is the context which allows me to judge that, by carrying over existing designs, which are already pretty dated in themselves, and also by comparison to their competitors, BA have missed a huge opportunity to innovate on the soon to join members of their fleet.
Stepping onto a BA A380 will hold no novelty. The 787 J class seat on QR gives enough of a signal that the BA CW equivalent on their 787 will be a huge disappointment.
