So, what exactly does the liquid rule entail? In a nutshell, it means that any liquid, gel, or aerosol in your carry-on must be in a container of 3.4 ounces (100 milliliters) or less, and fit in a clear, quart-sized zip-top bag. Think of it like packing a lunchbox - you've got to make sure everything fits neatly inside!
Now, you might be wondering what counts as a liquid or gel - toothpaste, shampoo, and lotion are all obvious ones, but what about makeup or hair gel? The TSA has a handy guide to help you figure it out, but a good rule of thumb is: if it's squishy or spillable, it's probably a liquid or gel!
And don't even get me started on exceptions - like baby formula, breast milk, or medications. These are all allowed in reasonable quantities, but be prepared to declare them at security and possibly have them screened separately. It's like declaring a gift at customs - you've got to be upfront and honest!
