During my annual inquisition (recurrent training) last month it was reported by the instructor that PDT is planning to hire 200-250 pilots in the next year. Many of the recent new hires have been very inexperienced pilots in the 500/50 range. I was recently flying with a new F/O and he happily stated that on that day he actually passed 700 hours of total time.
I believe to get the chance to interview at that experience level one has to be a graduate of UND, Perdue, or Southern Illinois University.
A couple of things to consider, is PDT a great place to work, not any more. However if you wish to get a great deal of flying experience in a short amount of time this is a place where it will happen. Unfortunately our future is tied directly to USAirways which is very uncertain at the present. We may all be looking for other employment very soon.
