Dummies: TSA Reminds Travelers Costco Cards Won’t Fly At Airport Security

TSA Reminds Travelers Costco Cards Won’t Fly At Airport Security: Costco may get you great deals on bulk snacks, but it won’t get you through airport security. Despite persistent Internet rumors, TSA made it clear — again — that your warehouse club card isn’t a valid form of ID for domestic flights. The myth recently resurfaced thanks to a food blog and a few hopeful Reddit posts, but TSA reminded travelers that Real ID or a passport is still the gold standard. So unless you're flying to the food court, leave that Costco card in your wallet.
