The biggest Piedmont complaints are aircraft type (prop) and bases. The 145 and PHL base are solving that. Older complains are training department too tough... Well, they are training future AA pilots so cowboy up! And last, stagnation of the company, with the new aircraft and flow, the lists are moving steadily.
PDT will look like a mini Envoy and AA will have its WO companies flowing at a roughly equal rate. The Envoy-PDT decision will come down to base preference, but right this minute and for a couple months PDT guys will upgrade quicker and flow quicker because of all the growth planned for PDT.
