It's a personal thing and choice based on personal circumstance, as is this job generally, and just IMHO, BA has so much to offer a UK based pilot, at whatever stage/age, I simply wouldn't blame anyone having a very serious look at it and don't believe UK based pilots can't see that! My only comment with regards to PENKO's statement! Those I know from within, all joiners within the last few years - 1 on the B763 and 1 on the B744 - couldn't be happier.
I have a 1000 hours wide-body, and found my world-wide long haul inspiring, fun and far less tiring than any multi-sector day! Very happy to have experienced it...
As I say, it's personal and whatever drives you, be it money, lifestyle or LHS, but big picture stuff - BA is still a good choice and very best of luck to those who wish to apply.
