I don't want to rain on your parade but whilst having some sort of plan isn't a bad thing but you can't be that specific 10 years out, well certainly not in aviation. Looking into my crystal ball the only thing I can guarantee with a high degree of certainty is BA won't be flying the 767 in 2022 and I will be retired
.
As for anything else: Nobody knows what shape aviation will be in, what form BA will be in or even if it will still exist and whether there will be any form of cadet entry scheme.
