The TSA’s secret handshake is called the 3-1-1 rule. It’s not a new yoga pose, I promise. It means: 3.4 ounces (100 ml) per container. That’s it. No giant shampoo bottles, no full-sized sunscreen. Just tiny, travel-friendly soldiers.
Then, those tiny soldiers all have to fit inside one quart-sized bag. Yes, one. Not two, not a gallon Ziploc. Just one sad, clear little pouch. And you get one bag per person.
So, if you’re bringing your entire skincare routine in 3-ounce jars? You’ll need to Marie Kondo that bag. Hard choices await, my friend.
What “Liquid” Actually Means (The Sneaky Stuff)
Here’s where it gets fun. The TSA has a very generous definition of “liquid.” It includes water, juice, soup, syrup, jams, jellies, and even creamy peanut butter. Sorry, PB&J enthusiasts. That jar of Nutella? Liquid. That yogurt you saved for the plane? Also liquid.
Even mascara counts. And sunscreen. And deodorant—the gel kind, anyway. Stick deodorant is fine (it’s a solid, which is magic). But if it’s gooey, spreadable, or pourable, it’s liquid. Fight me, TSA.
Oh, and snow globes? Yep. If it’s over 3.4 ounces, it’s going in the bin. Sorry, Grandma’s snow globe from the Grand Canyon. You had a good run.

The Exceptions (Because They Always Exist)
Are you a parent of a tiny human? You get a pass. Baby formula, breast milk, and juice for infants are allowed in reasonable amounts—even if they’re over 3.4 ounces. Just tell the agent before you set off the alarm. They’ve seen it all.
What about medication? Yes, you can bring liquid meds over 3.4 ounces. But keep them in their original bottles (with labels) and tell the nice TSA person. No, you cannot use this to sneak in 12 ounces of hot sauce. Nice try.
Ice packs for injuries? Allowed, if they’re frozen solid when you go through security. Melting slush? That’s liquid. So freeze that sucker hard. Like, “ice cube of vengeance” hard.
