I don't know anyone who had decided before starting the course which airline they wanted to work for. I certainly don't know anyone who focussed on one, and think it most unlikely that he or she would be successful. The airlines that profess a policy of only taking integrated graduates take very few newly-qualified pilots anyway; it seems most unwise to direct your whole training towards one airline, let alone one that isn't likely to take you on! As a ground instructor and flight instructor, and propping up a flying-club bar I know a lot of pilots, especially low-hour commercial pilots, so why have I never met anyone who directs his career in anything like this way, I wonder?
Hedges might have a point.
