Toss Your Liquids

The TSA’s 3-1-1 rule dictates that not only must liquids, gels, and aerosols measure 3.4 ounces (100ml) or less to pass security, their containers must also fit those petite dimensions. If you have a larger container with just an ounce of liquid inside, it can get discarded. Snacks often fall prey to this policy; even cupcakes have been jettisoned for questionable amounts of frosting.
