Now that the TA negotiated between American Airlines, Piedmont Airlines, and Piedmont pilots has served its purpose in pressuring Envoy's pilots to accept their new TA, what should be done with Piedmont Airlines? While 20 ERJ-145s are suppose to be coming too Piedmont starting in 2016, there isn't any new order for turboprops or regional jets to replace Piedmont's aging fleet of dash-8s. Why should American continue to bother with Piedmont?
