The rule itself is simple, but it feels like a math problem from your worst nightmare. You get 3.4 ounces (100 milliliters) per container, all stuffed into one quart-sized, clear, zip-top bag. That’s it. Think of it as a very strict friend who won’t let you bring more than one bottle of nail polish remover to a slumber party.
Here’s my trick: I now treat my liquids like a tiny travel zoo. Each bottle has to fit in the enclosure—er, bag—or it gets left behind. If your sunscreen is bigger than a hamster, it’s not coming. Sorry, hamster-sized lotions only.
Pro tip: Don’t be the person who tries to argue the “but it’s only half full” argument. The rules are about the container size, not the amount inside. That’s like saying you can drive a tank through a drive-thru because you only ate half the fries.
The Sneaky Exceptions (You Can Have Cake, Sorta)
Now, before you throw your hands up and swear off flying forever, hear me out: there are exceptions. Medication, baby formula, and breast milk are allowed in reasonable quantities. You might need to declare them, but they won’t toss your insulin because it’s in a 5-ounce bottle. Lifesavers, literally.

And guess what? Solid foods are mostly fine. So yes, you can bring that giant block of cheese from Wisconsin through security. Just don’t try to spread it as a liquid—they’ll smell the loophole from a mile away. I once tried to bring a jar of honey as a “travel souvenir.” Let’s just say the TSA agent and I had a very awkward conversation about bee products.
Also: gifts. If you’re bringing a fancy bottle of maple syrup for your aunt, put it in checked luggage. Nobody wants to explain to a federal officer why their carry-on smells like breakfast. Trust me.
