Why would they put the lounge in A, other than it has the room? I have to guess as profitable as that airport is for UA currently, and with the total passengers there, that they will be adding several more international flights going forward. I keep hearing rumors about CDG, and a flight to Santiago, Chile, as apparently there are a large number of travelers who go DEN to SCL, which I would love for some summertime skiing. But if they are really worried about it being used, why not include the Hawaii trips in Polaris, which would make this lounge truly valuable when flying though Denver.
