I havent tried to use my Costo Amex for lounge access yet, (in fact I just found out today that such a perk exists for Amex Platinum at all) but I was standing in a long security line at YYZ when I noticed the priority lane allowed Amex Platinum holders through. There was a poster showing 4 differnt platinum cards, none of which were the Costo Amex.

I flashed my Costco Amex at the airport employee "gatekeeper" and specifically asked if this card gets me in, she replied in teh affirmative and opended the "velvet rope" for me.
