The 3-1-1 rule is the Bible of airport security. Any liquid, gel, or aerosol over 3.4 ounces (100 ml) is a no-go. Yes, that includes your artisanal honey, your expensive face serum, and the soup you were hoping to eat at the gate.
Pro tip: “But it’s a solid at room temperature” will not work on the TSA agent. Peanut butter counts as a liquid. So does hummus. So does that weird mascara that you accidentally left in your carry-on since 2019.
Surprising fact: You can bring a 3.4-ounce container of liquid, but if it’s a gel-like substance that looks like a booger, they will test it with a swab. Don’t ask me how I know.
