Clearly the original post was referring to a JR FO swapping into a trip that was already crewed with a LCA. It has nothing to do with whether or not a LCA can WS or swap. The point being that DALPA said that the OE trip drop changes in the last TA would only Impact Sr FO's in a given category. Clearly that is complete BS on every level. It would have impacted all FO's whether they can hold LCA trips or not. The scenario above is one example but the glaring issue was the withholding of large numbers of trips in RVR bid packet by training scheduling. The water fall effect for FO bidding was going to be massive.
