Can I travel with water for baby formula on plane?

Yes, in 2026, you are absolutely allowed to bring water for baby formula on a plane, as it is classified as a "medically necessary liquid." This is an exception to the standard TSA and international "3-1-1" liquids rule, which usually restricts liquids to containers of 3.4 ounces (100ml) or less. You are permitted to carry a "reasonable quantity" of water, juice, or liquid formula required for the duration of your flight and any potential delays. At the security checkpoint, you must declare these items to the officers for separate screening. In 2026, security staff often use advanced scanners (like CT or vapor analysis) to test the liquid without opening the bottles. The baby does not always need to be present for you to carry expressed breast milk, but for water intended for formula, having the infant with you is standard protocol. To expedite the process, it is recommended to store the water in clear, translucent bottles and inform the agent immediately upon arrival at the security belt to avoid unnecessary bag searches.
