SkyWest. Hands down. They are growing, cannabilizing ASA, and the movement is fast. Regionals pay well, but the lifestyle, benefits, and corporate culture make it a pain as a career. The idea is you want to get in, do as much flying as possible, get your apps filled out and move on to a company that will take care of you and your family right. In the absence of such company, at least one that will pay you well for the headaches. Plus SkyWest offers you the possibility of junior upgrade quickly on the EMB120 which means you actually make enough to pay your rent AND student loans.
From a guy who stayed at ASA too long thinking it would get better. Living the good life at NetJets now.
