340drvr's right... probably won't end up being a big deal as most out there should, I imagine, have the hours necessary. Chances are that anything that comes out of Washington will have a grace period and the regionals can simply add an ATP check ride to the next sim session to sort things out.
However, having the crew all have 1500 and an ATP still won't sort crap pay/terrible schedules/long commutes/etc.
