Your goal shouldn't be on what crew bases the regional have. You never know what bases the airline would abandon.
Also, the "flow", don't rely on it. One economic downturn, you will be flowing for 10 years. There are some guys (without degrees) who have been hired through the United CPP program, however, it's contingent upon completion of their bachelors.
There's a lot of movement here in Air Wisconsin. You can reach captain upon reaching 1000 hrs SIC. Also, they are lacking CPT and Sim instructors, another pad on your resume if you so desire.
If you need to make more money, we have a lot of open time. There's an FO in Columbia that tries to fly whatever he can legally. He will hit 100k for this year w/o the bonuses.
