While movement at Compass is pretty impressive (or at least will be), if you're debating between living in base at an American WO vs commuting to Compass, I'd say live in base. Unless living in DFW is less than your ideal situation, I'd give Envoy a very close look. Not sure how long it'd take to hold DFW, but look at the big picture: if your end goal is to get to "mainline," especially AA, with their current plan of hiring through the flow (for better or worse, but them's the breaks), I'd go to Envoy in a heartbeat. And I'm saying that as a Compass captain. Compass is a fantastic place to work with great crews, reasonable hotels, and lots of movement, but a fair number of people have those things. By going to a non-WO, I recognize that I'm shooting myself in the foot a bit for going to American, since they're unlikely to hire me (since I'm not former military). Your mileage may vary, but I'd go to Envoy in your situation. If you'd be living in a Compass base, or want to live in a Compass base, I'd say hands down come to Compass. Living in base is that big. But that's just my 2 cents.

Compass is a fantastic place to come to for west coast bases and the quickest upgrade on the west coast, but that's not necessarily what everyone is looking for. Best of luck in your final decision!
