Can I take baby formula powder on a plane?

Can you bring baby formula on a plane. The TSA classifies baby formula as medically necessary, so you can pack as much baby formula as you need for the trip without being limited to the 3.4-ounce rule that applies to other liquids.



Yes, you are absolutely permitted to take baby formula powder on a plane, and it is exempt from the standard "3-1-1" liquid restrictions. TSA and international security agencies classify baby formula, breast milk, and toddler drinks as "medically necessary liquids" and powders. This means you can carry them in quantities exceeding 3.4 ounces (100ml) in your carry-on luggage. While powdered formula has no specific weight limit, TSA officers may require you to remove it from your bag for separate X-ray screening or manual inspection. For a smoother experience in 2026, it is recommended to keep the powder in its original, labeled packaging and to inform the officer at the start of the screening process. You do not even need to have your child traveling with you to bring these items. It is also wise to pack slightly more than you think you'll need to account for potential flight delays or cancellations.
