What You'll Learn

Formula is considered a medically necessary liquid
Formula, breast milk, toddler drinks, and baby/toddler food are considered medically necessary liquids by the TSA. This means that these items are exempt from the standard liquid restrictions at airport security. Passengers are allowed to carry formula, breast milk, and other toddler drinks in quantities greater than 3.4 ounces or 100 milliliters in their carry-on baggage. These liquids do not need to fit within a quart-sized bag, and the child does not need to be present or travelling with the passenger.
However, it is important to inform the TSA officer at the beginning of the screening process about carrying formula or other liquids in excess of 3.4 ounces. These items should be removed from the carry-on bag to be screened separately from other belongings. TSA officers may need to test these liquids for explosives or prohibited items, and it is helpful to have them in clear, translucent bottles.
Additionally, ice packs, freezer packs, gel packs, and other cooling accessories required for formula, breast milk, or toddler drinks are also allowed in carry-on baggage. These items will be subject to the same screening procedures as the liquids.
While formula is generally considered medically necessary, some variability exists across airports and TSA agents. Some travelers have reported being allowed to pass through security without any issues, while others have faced additional screening or requests to open and test the formula. Therefore, it is advisable to allow extra time when passing through security with formula or other medically necessary liquids.

No limit on the amount of formula you can carry
When travelling with an infant, you're allowed to carry infant formula, baby food, and sterilised water for the journey. There is no legal limit to the amount of formula you can carry, however, it is recommended to check with your airport before travelling. The TSA classifies baby formula as medically necessary, so you can pack enough formula for your trip without being limited to the 3.4-ounce rule that applies to other liquids.
Formula, breast milk, and baby food are considered medically necessary liquids. This also includes breast milk and formula cooling accessories, such as ice packs, freezer packs, and gel packs, regardless of the presence of breast milk. You do not need to have your child with you to bring these items. However, you must inform the TSA officer at the beginning of the screening process that you are carrying formula, and it should be screened separately from your other belongings.
TSA officers may need to test the liquids for explosives or prohibited items. It is helpful to have the formula in clear, translucent bottles rather than plastic bags or pouches. Additionally, it is recommended to leave extra time to go through security, as they may ask to open the bottles for testing, which you can politely refuse. They may then swab the outside of the bottles and perform additional screenings, which may include swabbing your hands and other bags.
It is important to note that rules can vary from country to country, so be sure to research the regulations at your specific travel destination. Checking the airport's website is usually a great way to find the necessary information.

The Transportation Security Administration (TSA) classifies infant formula as medically necessary, meaning that parents or guardians can pack as much as they need for their trip without being limited by the 3.4-ounce rule that applies to other liquids. This also applies to breast milk, toddler drinks, baby/toddler food, and related cooling accessories such as ice packs.
Parents or guardians should inform the TSA officer at the beginning of the screening process about the amount of formula they are carrying.

These items are allowed in carry-on baggage and do not need to fit within a quart-sized bag.

- Be prepared for different procedures at different airports. Some travellers have reported varying experiences, with some airports conducting thorough screenings, while others have been more relaxed.
- Consider using small, ready-made bottles or formula dispenser containers. These are easier for TSA officers to swab and screen, potentially speeding up the process.

Formula and travelling to/from the UK
When travelling to/from the UK with an infant, you're allowed to carry as much infant milk, baby food, powdered milk formula, and sterilised water as required for your trip. This applies even if the quantity exceeds the usual 100ml limit on liquids. However, it's important to be sensible and not carry 'unlimited' supplies. Make sure you have enough formula and water to last the flight, factoring in possible delays.
Powdered formula can be carried without restrictions, and it may be tested at airport security. Individual containers of breast milk must not exceed 2,000ml and may also be screened at the security point. Airport staff may need to open the containers for inspection. It is recommended to have these items readily accessible for inspection and to allow extra time for security checks.
If you prefer not to carry formula and water separately, you can bring ready-to-drink formula, which some parents have successfully taken through security without issues. Alternatively, you can order formula and other baby essentials from shops like Boots, collecting them at the airport after passing through security.
When travelling to the UK, it's important to check the country's restrictions on bringing in food items. Many countries, including the UK, have restrictions on certain types of food. For example, meat, fresh fruit, and vegetables are prohibited from being brought into many countries.
