Back from my "international" trip to Vancouver and had great success with *Gold Lounge Access privileges.

CLT-YYZ-YVR = US Airways Club Access in CLT, but not enough connection time for the Maple Leaf Lounge (MLL) in YYZ. I was too tired and it was too late to test access at MLL at YVR.

YVR-SFO-IAH-CLT = Maple Leaf Lounge Access at YVR, Red Carpet Club at SFO, and Presidents Club (Terminal B) at IAH. I even tried entry to the US Airways club at my destination (CLT) and they let me in there as well. That's access to 4 clubs in less than 20 hrs. I would have had a 5th (Presidents Club at SFO), but didn't want to leave the secured area.

Thanks for the advice on *Gold access. The biggest thing I learned was just to act like you belong there and they'll let you in with minimal questions.
