As a NW WorldClub member I have had mixed luck getting gate passes to get into a PC if I'm not flying (usually seeing someone else off at AUS). Until recently it was no problem but I tried twice in the last month and CO said no, and that I should get a pass from NW (now DL). The DL agents wouldn't do it since it's not a NW or DL club (plus they generally go out of their way to be unhelpful on all matters). In theory should I expect to be able to get a pass from CO in this situation?
