As a 5 year Republic guy..........I say go to Skywest. I have a few buddies over there who love it. They treat their people well, decent pay and looks like their growth will keep them the top tier Regional for MANY years to come. Republic is the COMPLETE opposite of everything I just mentioned and worse. I can't speak for Compass but again I highly recommend Skywest. If I could do it over Skywest is where I would have gone!
