So wrong!!!

Great Lakes is not a good choice unless you already live there simply because they are limited to the region around the Great Lakes. All other regionals have a much greater operational area of coverage. Plus the 1900 doesn't have a door in the cockpit.

Comair stands a very good chance of being comaired. Sure, people say they're just threats, but why else would it be called being comaired.

I would avoid California Pacific as I don't think they have any planes with with tail mounted engines. Delta (717, MD88, MD90) is unlikely to hire you without at least 500 hours of tail mount time.

Atlantic Coast Airlines? Do you mean Atlantic Southeast? ACA is mainline, not a regional.

I would recommend the OP go to one of these 3:

American Eagle
Delta Connection
United Express
