The magic number is 3.4 ounces (or 100 milliliters) per container. Yes, that’s roughly the size of a single-serve applesauce pouch or a small jam jar from a fancy hotel breakfast. All your liquids, gels, and aerosols must fit into one clear, quart-sized zip-top bag—think of it as the tiny VIP lounge for your toiletries.
Why does this matter? Because nobody wants to watch you dump a $40 bottle of fancy conditioner into a trash can. I’ve been that person, and it’s heartbreaking—like saying goodbye to a loyal friend in a sad airport security bin.
Everyday Items That Will Surprise You
It’s not just shampoo and toothpaste. Peanut butter, yogurt, and even your favorite jam count as liquids. Remember that time you tried to bring grandma’s homemade chutney? TSA sees it as a “gel,” and they will treat it with the same suspicion as a vial of nitroglycerin.
Even solid deodorant is fine, but spray or gel deodorant must obey the 3.4-ounce law. And your cute little bottle of hot sauce? Sorry, that’s a liquid too. Pro tip: If you can spill it, spread it, or spray it—it’s on the list.
