While quickly redacted after it was leaked, the damage was already done. This basically admits what many of us have been hinting at, in addition to the fact that the PSA 50 seat aircraft will be getting parked sooner: PSA won't be able to staff the CRJ-700 from Envoy and the ability to transfer the entire fleet won't happen.
In all likelihood, the only pilots that can staff those planes are the Envoy pilots. Unless you think the Envoy pilots would agree to come over with junior bidding ability and if you think American management would agree to pay Envoy pilots the same longevity scale, the majority of the planes will likely stay at Envoy.
To transfer the airplanes with the Envoy pilots coming over to PSA, would cause a 6 month training gap for each pilot, that the regional industry cannot sustain right now since it is already against the wall with tight staffing.
