As for the transfer, no, they are on separate work rules(Skywest isn't union), and a separate seniority list.

I know a couple FOs with both companies, and all of them like their respective employers. It sounds like QOL, work rules are about as good as you get with a regional. My friend at ASA has been there nearly a year. He's been on reserve the whole time but has enjoyed it. Recently chose to transfer to the 700 and sit on reserve a little longer for the increace in pay.
