Compass, without a doubt. And then Mesa. Skywest may be a great place to work but their upgrade is 7-8 years right now. I don't care how great a regional is, 7-8 years is a long time to
Sit in the right seat of an RJ.

Think of all the money you will have lost if you went to Compass or Mesa, upgraded in 16 months then onto a major 12-16 months after that. Meanwhile the Skywest guy is still sitting right seat on an RJ and the Mesa/Compass guy is already onto the right seat of a Boeing/airbus making 100k+ a year.

And for the guys saying Skywest's upgrade time is about to come down... Look at all the 50 seaters they have to shed in the next 5-10 years. It's going to be a wash at best there with 200s leaving and 175s arriving.
