Airline Rules for Toiletries

Airline Rules for Toiletriesに関する深掘り解説を丁寧に解説いたします。

First, the big one: the 3-1-1 rule. This means your liquids, gels, and aerosols must be in containers of 3.4 ounces (100 milliliters) or less. That’s about the size of a shot glass, which is ironic because you can’t bring a real shot of whiskey through security.

All those tiny bottles must fit into one clear, quart-sized zip-top bag. And I mean one—not two, not a “generously sized” freezer bag you found under the sink. The TSA has eagle eyes and a deep, personal hatred for extra bags.

This bag goes in a bin, all by itself, like a celebrity at a red carpet event. Don’t hide it in your suitcase pocket—they will find it, and they will make you dig it out while everyone behind you sighs dramatically.

What Counts as a Liquid? (Spoiler: Everything You Love)

Here’s a fun surprise: toothpaste counts as a liquid. So does your deodorant if it’s a gel or a spray. Also, shampoo, conditioner, lotion, sunscreen, mascara, and that fancy face serum that costs more than your flight.

Even peanut butter is a liquid. Yes, peanut butter. The TSA has declared war on nut-based spreads, presumably because they’re afraid someone might smuggle a spoon in their carry-on. If you can smear it, squeeze it, or spread it, it’s a liquid.

And don’t get me started on snow globes. You cannot bring a snow globe larger than a tennis ball. Why? Because apparently, the TSA is convinced you’ll use glittery water to take down a plane. I’m not making this up.
