Trying to find a company where you respect their ideals or philosophy is b*****cks. They're all broadly the same and are all run by fairly ruthless business realities.
That's absolutely the truth. There may have been a time when an airline or any company was almost family. Some companies still pay lip service to it. It came from the time when you joined a company you stayed there to the pension. Not any more. It's even fading a bit from the military. The old Imperial Airways mentality.
Whether or not you are devoted to getting into BA or whoever, it doesn't matter. It's just another job at the end of the day. Except that in BA you'll have to wait that much longer to get command.
Take the first job you're offered because it may be the only job you're offered.
