From our Travel Insurer:

With the rules of airport travel changing frequently, it can sometimes get tricky knowing what is and isn’t allowed in your bags. The United States Transportation Security AdministrationTSA) implements air-travel regulations tofollow. To ensure safety, the TSA has placed strict rules on the volume and type of liquids allowed on an airplane. Here are the main rules for liquids so you can get through the airport’s security checkpoint quickly, and avoid having your toiletries and other liquids confiscated!
3-1-1 for carry-ons rule – Liquids, gels, aerosols, and creams must be 3.4 ounces (100ml) or less per container, they must be in 1 quart-sized, clear, plastic, zip-top bag, and 1 bag per passenger placed in screening bin. The bag limits the total liquid volume each traveler can bring on board.
The Exception – Medications and baby food/formula are allowed in reasonable quantities exceeding three ounces, and they don’t have to be in the zip-top bag. Declare these items for inspection at the beginning of the checkpoint. TSA officers may need to open them for additional screening, so be prepared.
When You Aren’t Sure – Place your liquids, gels, aerosols, creams and pastes in checked baggage if you aren’t able to transfer them to a smaller container. There is no volume limit for liquids in checked baggage, but just remember – liquids add a significant weight to your suitcase, which could add you an extra fee.
