And go look at ATP, too. They could turn out to be a good fit. Just don't make a decision without checking out the smaller schools as well, for a comparasion, and don't buy off on any big schools marketing department hype or stuff they preach at their website.
Talk to people who have been through the program and see how it turned out for them. You could save a lot of money by working with a smaller school, taking your time, and end up a better pilot for it. Don't buy into the "seniority is everything so you must hurry, hurry, hurry". I'd rather see a guy take his time and become a seasoned pilot before he jumps into an RJ.
Also, at 18, a guy needs to be thinking about getting the degree as well as flying.
