Does baby milk count as liquid on plane?

Formula, breast milk, toddler drinks, and baby/toddler food (to include puree pouches) are considered medically necessary liquids. This also applies to breast milk and formula cooling accessories, such as ice packs, freezer packs, and gel packs (regardless of presence of breast milk).



While baby milk (including formula, breast milk, and sterilized water) is technically a liquid, it is exempt from the standard 100ml (3.4 oz) limit on flights. In 2026, parents are allowed to carry "reasonable quantities" of baby milk in their carry-on luggage to sustain the child for the duration of the journey and any potential delays. At airports equipped with C3 security scanners, you may even be able to leave these liquids inside your bag in quantities up to 2 liters. At standard checkpoints, you must remove the milk for separate screening. The TSA and UK authorities note that the child does not need to be present for you to carry breast milk. Be prepared for the liquids to be tested for explosives using vapor analysis or other non-invasive technology; you can request a private screening if you prefer.
