JetBlue’s regency requirement is 200 hours in the last 12 months and is pretty firm. Can’t speak for any other airlines. But regional pay/bonuses are pretty decent these days. No different (in some cases better) than year 1 pay at majors used to be. Throw in O5 (or whatever) retirement and you should make livable wages at a regional. Your stay at the regionals will likely be short. Months, I’d guess.
