Can I take 3.38 oz on a plane?

Each passenger may carry liquids, gels and aerosols in travel-size containers that are 3.4 ounces or100 milliliters. Each passenger is limited to one quart-size bag of liquids, gels and aerosols.



Yes, you can take 3.38 oz (100 ml) of liquid in your carry-on bag in 2026. The Transportation Security Administration (TSA) and international aviation authorities follow the "3-1-1" rule, which allows for containers that are 3.4 ounces (100 milliliters) or less. Since 3.38 oz is slightly less than the 3.4 oz limit, it is perfectly legal. All such containers must fit comfortably within a single, clear, quart-sized, zip-top plastic bag. It is important to note that the rule applies to the container size, not the amount of liquid inside; if you have a 5 oz bottle that only has 1 oz of liquid left, security will likely confiscate it. In 2026, many airports are installing new CT scanners that allow passengers to leave liquids inside their bags, but the volume restriction remains in place unless you are traveling through specific "liquid-friendly" airports in the UK or EU that have fully transitioned to advanced 3D scanning technology. Always check your specific departure airport's current tech status to see if you need to remove the bag from your luggage.
