Just a quick question, what's with the hostility directed towards any wannabee who shows a direct enthusiasm towards joining an airline, or shooting for a cadetship etc? I've got my own views, and agree with the value of GA, but I fully support a trainee who is specifically aiming to join the big boys, and cites that ambition as the reason they got into flying.
It's like saying someone who gets a shot at the AIS for Cricket, should ignore that and spend a few years at their local cricket club slogging it out instead. I completely and utterly agree that a few years of 'real' flying enhances a pilot's skill base and issues an abundance of invaluable experiences, but if GA doesn't interest you, and your sole ambition is a career with an airline, then why take the scenic route to get there (if you don't have to)?
Not doubt I'll attract some personal criticism, but would love to hear some other viewpoints - and i'm sure I will.
