I have to agree. NMB is not a part of this and this is for past actions of Polar Air Cargo, not future. The "Single carrier" status is a present and future look, where Polar CM's are trying to be made whole on violations of their contract years ago.
All I've heard, rumor wise is, Polaroids wondering how much their going to get, and some others pointing out that the foundation of the Polar complaint is the fact that Polar and Atlas are not merging. This is where the NMB ruling may be coming in.
Some felt the Arbitrator was waiting for "Single Carrier" status to be ruled on to make his decision. Since the Polar MEC made clear that there was no merger in the hearings, Bloc is giving them a chance to adjust to reality.
