Thanks, MaxThrust! Very helpful.
The truth is I'm not certain I even want to make it to the majors. I realize it's basically the ultimate goal for most pilots but I also have an idea what that life is like. I could spend months or years on reserve, I'd start at the bottom all over again, etc., etc.
I also accept that no amount of research will predict just how much time or money I'll have to invest and it won't be easy. I'm pretty flexible as to where I ultimately end up-just as long as I can feed myself! :-)
Once again, thanks for your response-that was a lot of help.
