Can You Bring Formula Through TSA? A Mom’s Guide to Flying With Formula

Yes, you can bring baby formula through TSA. Formula is considered a medically necessary liquid, which means you can bring more than the standard 3.4-ounce liquid limit through airport security. You can also bring water for preparing formula, and TSA allows cooling accessories like ice packs if you need them.

If you’re flying with formula for the first time, though, knowing that it’s allowed is only part of the equation. After flying 20+ times with my kids, I’ve learned that how you pack your formula can make feeding your baby on the plane so much easier. I currently fly with powdered formula, and my biggest advice is simple: pre-measure everything before you leave home.

Can You Bring Baby Formula Through TSA?

Yes. TSA allows baby formula in carry-on luggage in reasonable quantities, including quantities greater than 3.4 ounces. Formula does not need to fit inside your quart-size liquids bag.

TSA considers formula, breast milk, toddler drinks, and baby and toddler food to be medically necessary liquids. If you need to keep formula cold, cooling accessories like ice packs, freezer packs, and gel packs are also allowed. Your formula and water may require additional screening, which is normal and one reason I always recommend giving yourself some extra time at airport security when you’re traveling with a baby.

Can You Bring Powdered Formula Through TSA?

Yes, you can bring powdered baby formula through TSA, and this is actually my preferred way to travel with formula. Instead of making bottles ahead of time, I pre-measure the exact amount of powdered formula I’ll need into a formula dispenser before we leave, and I also pre-measure the water into my baby’s bottles.

When she needs to eat, all I have to do is pour one compartment of formula into the bottle, shake it, and feed her. There is no measuring, scooping, or pouring water while I’m trying to hold a baby on a plane. Trust me, you do not want to be balancing a formula can and tiny scoop while your baby is screaming and you’re squeezed into an airplane seat, so make it as easy on yourself as possible.

Can You Bring Water Through TSA for Baby Formula?

Yes. TSA allows water needed to prepare baby formula through security in reasonable quantities as part of its exemption for medically necessary infant and toddler liquids.

I pre-measure the water directly into my bottles before we leave for the airport. I typically travel with at least three bottles, so they’re already filled with the correct amount of water for each feeding. That means when it’s time to make a bottle, I don’t have to measure water on the plane.

I also bring my own Owala water bottle, but I usually take that through security empty and fill it at a water fountain once we’re on the other side. Having the baby’s bottles ready to go while keeping my own water bottle empty makes getting through security and onto the plane pretty simple.

Does Baby Formula Get Screened by TSA?

It can, so give yourself a little extra time at airport security. TSA instructs travelers to let the officer know when they’re carrying formula or other medically necessary liquids over 3.4 ounces and to remove those items from their carry-on so they can be screened separately.

In my experience, traveling with formula and water can mean your bag gets pulled aside for additional screening. I try to keep all of the bottles and formula together and easy to access instead of burying everything throughout the diaper bag.

Most importantly, don’t panic if your formula gets pulled aside. Additional screening is normal, and you’re allowed to travel with your baby’s formula. Factor the extra screening time into your airport plans and move on.

How Much Formula Should You Bring on a Plane?

My rule is to bring at least twice as much formula as I think I’ll need for the actual flight. If I expect my baby to need two bottles, I’m not packing exactly enough for two bottles because flights get delayed, you can sit on the tarmac, connections get missed, and a travel day can unexpectedly become much longer than you planned.

Running out of formula is one travel problem I never want to have, so I keep the formula I expect to use during the flight in my diaper bag underneath the seat in front of me. I don’t want to have to get into the overhead bin every time my baby needs a bottle.

I also keep a can of formula in my roller carry-on as backup. If we’re taking a longer trip, I’ll either pack additional formula in our checked suitcase or buy more once we arrive if I know our formula is readily available at our destination.

My biggest advice is not to put your entire formula supply in your checked luggage. If your suitcase is delayed or lost, you still want enough formula with you to comfortably feed your baby.

Do You Need a Cooler for Formula on a Plane?

It depends on how you’re traveling with it. Because I bring powdered formula and don’t mix it until my baby is ready to eat, I don’t need to travel with a cooler or ice packs, which is one of the reasons I find this system so easy.

If you’re traveling with prepared liquid formula or bottles that need to stay cold, TSA allows cooling accessories such as ice packs, freezer packs, and gel packs. Just remember that these items may also need additional screening.

Exactly How I Pack Formula for a Flight

I try to eliminate as many steps as possible before we even leave for the airport. In my diaper bag, I keep at least three bottles with the correct amount of water already measured into them, a formula dispenser with each feeding already portioned out, and enough formula for at least twice as many feeds as I expect my baby to need.

The diaper bag stays under the seat in front of me so I can reach everything without getting up. This is also why I’m very intentional about what I pack in my diaper bag when we fly because I want the things I’ll actually use during the flight within arm’s reach.

I also bring a travel bottle washing kit with a bottle brush and cleaning supplies. Ideally, I bring enough clean bottles that I don’t need to worry about thoroughly washing them during the flight, and then I clean everything properly once we reach our destination.

Why I Don’t Pre-Make Bottles Before a Flight

For me, powdered formula plus pre-measured water is the easiest combination. I intentionally try not to get my babies dependent on warm bottles, so since I put the water in the bottles before we leave home, it’s room temperature by the time we need it.

That means I don’t have to find hot water, ask a flight attendant to warm a bottle, or figure out how to get a bottle to the right temperature while we’re traveling. When my baby gets hungry, I grab a bottle, empty one section of the formula dispenser into it, shake it, and we’re ready. When you’re flying with a baby, fewer steps are almost always better.

My Biggest Tip for Flying With Formula: Pre-Measure Everything

If you take one thing from this article, make it this: do as much as you possibly can at home. Pre-measure the formula, pre-measure the water, have your bottles accessible, and pack more formula than you think you’ll need.

Trying to scoop powdered formula out of a can while you’re holding a baby in your lap is unnecessarily stressful. The scoop can spill, the powder can go everywhere, and your baby probably isn’t going to patiently wait while you measure everything.

There are already enough moving pieces when you’re flying with a baby, so feeding them doesn’t need to be one of the complicated ones. A few minutes of prep before you leave home can make a huge difference once you’re actually on the plane.

Don’t Stress About Bringing Formula Through TSA

I know airport security can feel intimidating when you’re bringing something that doesn’t follow the normal liquid rules, especially the first time you fly with a baby. But formula is specifically addressed in TSA’s rules, is considered medically necessary, and can be brought through airport security in reasonable quantities.

Your formula or water may need additional screening, so give yourself extra time and keep everything easy to access. I would spend much more energy making sure you have enough formula for unexpected travel delays than worrying about bringing it through TSA.

Pack more than you need, pre-measure everything you can, and keep the bottles you’ll need during the flight within arm’s reach. The goal is to make feeding your baby one of the easiest parts of your travel day.

Frequently Asked Questions About Bringing Formula Through TSA

Can you bring formula through TSA?

Yes. TSA allows baby formula in carry-on luggage in reasonable quantities. Formula is considered a medically necessary liquid, so it can exceed the standard 3.4-ounce liquid limit.

Can you bring powdered formula on a plane?

Yes. You can bring powdered baby formula in your carry-on. I personally pre-measure individual feedings into a formula dispenser because it makes preparing bottles on the plane much easier.

Can you bring water through TSA for baby formula?

Yes. TSA allows water needed to prepare baby formula in reasonable quantities. It may require additional screening when you go through security.

Does baby formula have to be in your liquids bag?

No. Formula in quantities greater than 3.4 ounces does not need to fit inside your quart-size liquids bag. TSA treats baby formula as a medically necessary liquid, so it falls under different rules from your regular carry-on liquids.

Can you bring ready-to-feed formula through TSA?

Yes. Ready-to-feed liquid baby formula can be brought through TSA in reasonable quantities and is exempt from the standard 3.4-ounce limit. Like other baby-feeding liquids, it may be subject to additional screening.

Can you bring ice packs for formula through TSA?

Yes. TSA permits ice packs, freezer packs, and gel packs needed to keep formula cold. These cooling accessories may also require additional screening as you go through security.

How much formula should I bring on a flight?

TSA uses the standard of a “reasonable quantity” rather than giving parents a specific number of bottles. Personally, I bring at least twice as much formula as I expect my baby to drink during the flight, plus backup formula in my carry-on in case we experience a delay.

Should I pack formula in my carry-on or checked luggage?

I keep the formula I’ll need during the travel day in my diaper bag and additional backup formula in my roller carry-on. I may put additional formula in a checked suitcase for a longer trip, but I never want my entire supply in checked luggage in case our bags are delayed or lost.

Do I need to tell TSA I have baby formula?

TSA instructs travelers carrying formula or other medically necessary liquids over 3.4 ounces to tell the TSA officer at the beginning of the screening process and remove those items from their carry-on for separate screening. I recommend keeping your formula, bottles, and water together and easy to access to make the process as simple as possible.
