I'll be at the CTP/ATP course in a month and almost finished with my FW stuff. Had an offer from Envoy and Compass (only two I applied to), chose Compass, would do it again.
Most RTP guys I know are going to Envoy, but you'll see tons of negativity about reserve rules, displacements, forced upgrades where you'll switch air frames and bases, flow for new hires is about nine years, and on and on. Then you have to go to Coast to do your ratings and time building which has a big backlog right now. I got the CJO back in May, couldn't get me to Coast until January. Don't know what it's looking like right now, but hear it's still a long wait. Then you'll have to go to Texas, live there college style with roommates, leave any family behind for that time, etc.
With Coast, you choose a 141 school near you or whatever is cheapest that you don't mind going to. They'll pay the school directly, you fly, that's it.
Is convenient for me since I'm at home in Colorado Springs, using an AF Aero Club that is only $93/hr for a T41C (210hp 172), $99 for a T41D (210hp, IFR, constant speed prop), $145 182RG, and $244 for a 600hp Baron.
I got in the club when the VA was still paying for the private add-on, but they stopped paying for that around May or so. Between the GI Bill and Compass I won't come out of pocket at all. Once you get your instrument, go IFR everywhere with a safety pilot so you can both log PIC time and split the cost.
