I don't think you can just go through the BA cadet programme.
I suspect you might have to do a bit of selection first, like.
I would be about 30 when I start off as a pilot (hopefully!). But will this be worth it?
What do you mean?
Can those straight out of flight training be on 767 with BA?
Do you think they'll still have them in like 10 years?
And finally, as I said the US is my second home. Should I decide to move there; will my flight experience from BA count?
Of course not, your standards will be far too high and you will need retraining.
