After reading for months in the forum about CPP and flows, I must say I wouldn't choose a regional based on that. Too many different facts/numbers that don't match what was promised by recruiters, etc.
It seems to me that Skywest, with its pros/cons and new contract offers more than other options initially. With its size and network it must be easier to pick up more flying and stay busy.
And I'm approaching my 40s slowly, wasn't born yesterday, not expecting to be on a regional 1.5 years and then go to a major. It'll take whatever it has to take, simple.
