All those tiny bottles must fit into one single, clear, quart-sized zip-top bag. That means no huge baggies or multiple bags—one bag per passenger. It’s a quart-sized bag, not a gallon one (leave that for your beach towel).
Place that bag separately in a bin at security. Don’t bury it in your backpack; the TSA officer wants to see it like a proud parent at a science fair. If you’re a frequent flyer, get a reusable clear bag—it feels so official!
