Basically, to get on with an airline you`ll need some hours.A lot of people become flight instructors, while others fly sky divers, do cropdusting, aerials, and some get into bush flying. The best way to get these jobs is to hang out at airports that have these operators, and get to know the people. You might not be hired on the spot, but one day they might be searching for a co-pilot and give you a call. But to be honest, it is hard to get a job flying these days.
