Wild Guess Alert
With the rush to get the SLI done and the timing of the fleet changes and the fact that an aircraft change would be an entire training cycle....
IF it is true that Delta is delaying their hiring THEN my guess is that there will be displaced NWA pilots on a Delta advanced entitlement bid within the next five months.
Makes more sense than hiring to furlough. Explains the urgency and I think would be approved by the FAA, even with separate certificates. Requires an airplane change & full training cycle.
My theory could be shot down (or confirmed) fast by someone with intricate knowledge of the NWA transition agreement. Are the bidding requirements a minimum limit, or a maximum limit? Can they do bids faster than the transition agreement? Can management be in compliance faster than agreed? I bet the answer is yes.
This seems like something that is a "nice to have" that could go either way. ACL65's comment went over my head, but I think one reason for the cancellation of the displacement was that things are moving too fast to train up pilots when the bids are going to be overcome by events.
Occam, FDJ2 (where's he been) and others - am I nuts?
