Spawney. If you're worth your salt, you'll sort the wheat from the chaff and come to your own conclusions. There's some good advice here (look carefully). You're right in saying that pay is a consideration, but they're right when saying that pay shouldn't be a driver...
If you want a bit of both, work hard, get in, work harder, earn a pittance, get out, work less hard, earn a packet. Look on it as an apprenticeship and you'll not go far wrong. For guys joining these days, the military is much more of a "job" than a " career", just don't say that at OASC and don't go around (presuming you get in) saying "I'm only doing this until I get a job with the airlines". As you have seen, this kind of approach can rub the old school up the wrong way...
Whatever you do, good luck, but don't be quite so keen to rise to the bait old boy...
