I’d say take the one that’ll get you based where you want to be the fastest. You won’t dislike SkyWest if you go there (I speak from experience,) but living in base is a jewel, especially during your first year at the regionals. I know SkyWesters who abhor their job, and I know Mesa guys who love their job. It’s all subjective, but live in base if you can.

EDIT: Also, people here are talking about ACMIs and stuff, UPGRADE AT YOUR REGIONAL FIRST AND GET PIC TIME. Makes it easier to move on to better things if you don’t like the ACMI life (that’s also from experience.)
