2. Medications: You can carry medical liquids, aerosols, or gels through security. Medicines like cough syrup, ice packs, pain relief gels etc are allowed. You need not store them in a plastic, transparent, or resealable container. However, you must remove them from your carry-on luggage for security checks.

Tips to Help you Navigate through the 311 Liquid Rule Smoothly

1. Plan Ahead: Before your next trip, glance at the number and types of liquids you carry. Identify which liquids are considered gels, aerosols, sprays, etc. This will help you plan in advance and according to the TSA precheck rule. 
2. Invest in Travel-Sized Containers: Always buy travel-sized mini containers that meet the TSA requirements for carrying liquids. These containers are usually around 3.4 ounces or less in capacity and are ideal for transferring your favorite toiletries. 
3. Consolidate Your Liquids: Consolidate all the permissible liquids in one quart-sized container. Acceptable liquids include shampoo, conditioner, body lotion, shower gels, toothpaste, etc. Keep all these liquids in one bag. This makes it easier for the TSA officers to screen and verify during security checks. 
4. Know Your Exemptions: Remember the exemptions to the 311 rule mentioned above. These are for essential items such as medications, baby formula, and breast milk. Although they are allowed, inform the TSA officers if they exceed 3.4 ounces. 
5. Keep It Accessible: Pack your quart-sized containers in a way that makes them easily accessible. This will allow you to remove and place them back during the security checks, saving time and reducing the hassle. 
6. Consider Alternative Options: If you’re unsure about carrying certain liquids or want to minimize them, consider alternative options. For example, you can carry solid toiletries or powdered formulas instead of shower gels or baby formula. This will help simplify your packing process and reduce the need for additional screening. 
7. Stay Updated: Stay updated with any changes regarding the 311 rule that come with regulations or the security check-in process. You can find out from the TSA’s official website or mobile app or call the airlines for the latest guidelines.
