Back to the subject, my top picks were:

1. Republic
2. Expressjet
3. Skywest
4. Pinnacle
5. American Eagle

Republic for the upgrade, bases and expected growth. Expressjet for the bases but worried about the branded stuff. Skywest is good but no Texas bases. Pinnacle for the fast upgrade but I wasn't interested in the bases. Eagle for the base but the upgrade time is aweful, that could change but its a long time right now. They are a stable company though.
