Last time I checked there was a merged seniority list, agreed on by both MECs; as well as a merged company, operating two certificates. The entire planet with the exception of Robbobin knows Atlas and Polar are merging. Even ALPA (finally) wants the single CBA finished. The seniority list is what the NMB will look at to determine if the cards were furnished by eligible pilots. Send in your cards and join your Polar brothers who can actually read the writing on the wall.
