If I were picking a regional now it would be a wholly owned regional. The American regionals have a flow program. Do your homework. Horizon is a WO, BUT they have no bonus, no flow through and first year pay you would have to work a job on the side to pay your bills in the PNW.
Compass just lost 6 airplanes and are now overstaffed and no training dates until March. Why is MESA even on your list - again -do your homework. You can PM me if you have any questions.
