RAH- Have a few friends I use to fly with that have been there 3 yrs+ and they don't see an upgrade anytime soon.
CommuteAir- I have turb time, it feels more like a horizontal move.
Airwisky, Envoy and a few others - Upgrade times are horrible.
Compass- junior base is on the west coast.

Mesa was a good choice for me and I do have a few friends here that already told me its just a job and it isn't really that bad once you have a plan.
