Complete Guide to TSA Liquid Rules

Flying can be complicated if you're not aware of the Transportation Security Administration's (TSA) 3-1-1 guidelines for transporting liquids in carry-on luggage. Let's simplify the process and get where you're going!

The TSA's 3-1-1 Rule

Since 2006, the number of liquid passengers can bring on an aircraft are limited due to security threats. This rule states that all liquids must be less than 100ml or 3.4 ounces. These liquids must be placed in a quart-sized, clear bag. Only one bag per traveler is permitted.

Exceptions to the 3-1-1 Rule

Exemptions for medically necessary liquids, formula, and breast milk are allowed on board with additional security measures (typically an X-ray). Duty-free goods, and hand sanitizer both have a special status, as well as liquids purchased after the airport security checkpoint.

Tips for Liquids in Carry-on Bags

Save space switching liquids for solids, like perfume bars, and solid shampoo. Buy the liquids you need at your destination. Most airports have drugstores. Prepare for messes with a small hand towel curled around your bag of 100ml liquids.
