24G: I think you'll find that at most regionals the upgrade times will start to decrease because just about everyone is starting to hire again. I worked at Comair, and I think the upgrade time now is somewhere between 4-6 years. I have heard that at some other places like Pinnacle, Mesa and Chataqua that the upgrade times are much shorter. I upgraded at my first opportunity which was at the 4 year mark. Good luck!!!
