Costco cards might get you discounts on travel and vacations, but it can not get you onto a plane. With the Real ID requirement now in place, those lacking one are weighing their options when it comes to flying. Rumors across social media have spread saying that Costco Membership cards could be used in place of a Real ID.

Costco loyalists have long praised the warehouse giant for its unbeatable bulk deals and generous return policy—but lately, some everyday items just don’t seem worth the trip (or the membership fee).

In addition to Real IDs, passports, passport cards, U.S. Department of Defense IDs and DHS trusted traveler cards are considered acceptable forms of identification at TSA checkpoints. A full list of acceptable forms of identification can be found on the TSA website. The TSA says the list of acceptable IDs is subject to change without notice.
