Can you take baby formula on a plane UK?

Baby food and baby milk When travelling with a baby you're allowed to take enough baby food, baby milk and sterilised water for the journey. There is no legal limit to how much you can take however check with your airport before you travel.



Yes, you can take baby formula on a plane in the UK in 2026, and it is exempt from the standard 100ml liquid limit. You are allowed to carry enough baby milk (powdered or liquid), sterilized water, and baby food for the duration of your journey. A supportive peer "security" tip: be prepared for the fact that airport security officers will likely screen the liquids separately. They may use a specialized "liquid analyzer" or ask you to open a container to verify the contents. There is no legal "limit" to the volume, but it must be a "reasonable" amount for the trip. Notably, by 2026, most major UK airports (like LHR, MAN, and BHX) have installed CT scanners that allow you to keep these items inside your bag, though you should still declare them to the staff to avoid unnecessary secondary searches or delays during the screening process.
