As a DM, whenever I book travel with companions (with the same PNR as me), they get access to C+. If I decide to burn a RUC on a trip, will that somehow cause my companions to lose their C+ seats? On the one hand, I can't imagine why it would: after all, if my RUC doesn't clear, then I'm still with my companions in C+. But, if I clear in advance, does that jeopardize their seat assignments and SP access?
