I can echo much of what the more experienced people have already said. I was one of the guys that got hired by eagle and was sent to an RJ class. When I went, I had 550TT/50ME. I was the HIGHEST time guy in the RJ class, and the only CFI/CFII, 250 dual given at the time. This may scare some of the older guys, but the lowest time guy was 210TT/100ME.

I would highly recommend instructing for a while. You don't really know the material until you can teach it. And you'll REALLY know it when you can teach the same concept 5 different ways. The industry now just is not demanding pilots, even CFI jobs are hard to come by.

-Instruct, learn how to teach and grow in knowledge.
-Fly freight, test your limits and practice what you taught.
-Then go the airlines and transport people safely.

Three pieces of advice given to me by a wise man once:
Persistance is key
Never stop learning
Realize that you'll never have a career in aviaion, just a series of "gigs."
