Sailing Through Security: The Truth About TSA’s Liquid Rules
Changes in latitudes, changes in attitudes—and let’s be honest, sometimes a few changes at airport security.
If you’ve been scrolling through travel headlines lately, you might have heard whispers that you can suddenly pack full-sized bottles of suntan lotion, hot sauce, or your favorite rum mixer straight into your carry-on. Before you go tossing 12-ounce bottles into your duffel and heading for the gate with a margarita in hand, let’s pour a little cold water on the rumors and get down to the real rules.
Here at Come Monday Travel, we believe travel should be smooth sailing from the moment you leave your front porch. Here’s the straight-up, authoritative breakdown of what’s really going on with TSA liquid rules so you don’t end up losing your favorite gear at the checkpoint.
The Reality Check: Is the 3-1-1 Rule Still Standing?
The Short Answer: Yes, the 3-1-1 rule is still very much alive and kicking.
Unless you want to watch the TSA officer gently deposit your favorite fancy coconut conditioner into the bin of lost dreams, stick to the basics for your carry-on:
3.4 Ounces (100ml) or Less: Every liquid, gel, aerosol, cream, or paste must be in a container this size or smaller.
(Pro-tip: TSA looks at the container size marked on the bottle, not how much liquid is left inside!) 1 Clear Quart-Sized Bag: All those little bottles have to fit inside one clear, zip-top quart bag.
1 Bag Per Passenger: One bag per traveler.
No sharing or squeezing extra space into your mate's luggage.
So, What Can You Bring in Larger Sizes? (The Exemptions)
While the standard rules apply to everyday toiletries, TSA does allow a few special exceptions for full-sized liquids in your carry-on.
Medications: Necessary liquid, gel, or aerosol prescription and over-the-counter medicines.
Infant & Child Care: Baby formula, breast milk, toddler drinks, and baby food.
Cooling Packs: Ice or gel packs needed to keep medical items or infant food cold.
Duty-Free Goodies: If you buy a bottle at the airport duty-free shop after security, it’s safe to bring on board (provided it stays sealed in its official tamper-evident bag with the receipt).
What About Those Fancy New Airport Scanners?
You might have heard that some airports are getting high-tech 3D scanners (CT technology) that allow passengers to keep liquids inside their bags. It’s true—technology is improving, and at certain modern terminals, you don’t even have to pull your 3-1-1 bag out of your luggage.
However, the size limits haven't changed. Even with the new machines, the 3.4-ounce limit per container remains the standard rule across U.S. airports.
