bag_dimensions.jpgThere are strict new rules about carrying on liquids. This link has all the info. The photo at left is an example of the TSA’s 3-1-1 rule: containers of 3 ounces or less in 1 ziplock-type bag with a 1-quart capacity (one bag per passenger). Download the latest TSA prohibited items brochure here in PDF format.

Some confusion has arisen because the inital TSA rule allowed for 3.4 ounces of liquid or gel, and - surprise, surprise - there is some inconsistency in the way even the current rules are enforced. Four-ounce toothpaste sometimes gets waved through, sometimes hits the garbage. And, there is nothing in TSA literature that prohibits carrying liquids in unmarked containers of the proper size (three ounces or less), but sometimes unmarked bottles get tossed. I’ve transferred my handsoap which I use for laundry (see below) to empty two-ounce hand sanitizer bottles rather than risk the unmarked bottle thing. Please share your carry-on liquid experiences - provided they’re not too sticky.
For convenience’ sake, you can buy almost anything in TSA-approved travel sizes here
