TSA Regulation for Bringing Water for Baby Formula on a Plane
The Transportation Security Administration has some strict rules about bringing formula on a plane, but we’ve got the scoop on how to make sure you don’t get in trouble.
The 3-1-1 Rule for Liquids
If you’re traveling with a baby, you might be wondering what TSA regulations say about bringing water for baby formula on the plane.
The 3-1-1 rule for liquids is pretty straightforward:
- 3 oz or Less per Container
- 1 Quart-Sized Bag (No Larger Than a 1 Gallon Bag) Per Person
- 1 Bag per Carry-on
When traveling with carry-on bags, passengers can bring reasonable quantities of baby food on board. However, it must adhere to the TSA’s screening process. Baby food must be in containers of 3 oz or less. All containers must not exceed one gallon’s worth of bottles. Also, passengers must place all small containers of baby food in a quart-sized bag for screening. When you pack for a flight with a baby, consider how much baby food you will need. Kindly pack accordingly to ensure a smooth screening process.
Exceptions for Baby Formula, Breast Milk, and Juice for Infants and Toddlers
When you take on a plane, TSA regulation permit some exceptions with your baby’s food. You can carry medically necessary liquids, such as baby formula or breast milk, in quantities over 3.4 ounces. Just ensure they undergo separate screening at security. When you take a plane, TSA regulations permit some exceptions with your baby’s food. You can carry medically necessary liquids, such as baby formula or breast milk, in quantities over 3.4 ounces. Just ensure they undergo separate screening at security.
You can also carry frozen gel packs, freezer packs, or partially frozen liquids in your carry-on bag or diaper bag. However, the final decision rests with TSA agents, who may consider your baby’s formula or breast milk toddler drinks as medically necessary liquids.
It’s essential to declare any concealed prohibited items and carry a letter from your doctor if required. If TSA denies you bringing your baby’s formula, you may want to pack it in a checked bag instead.

Quantity Limits for Exempted Liquids
You can bring up to 100 milliliters of formula, breast milk, or juice for babies on a plane. The TSA regulation will allow you to bring the liquids in a bottle that is 3.4 ounces or less in size, but only if it has a spill-proof cap.
How to Declare and Present Exempted Liquids at Security Checkpoints
Here’s what you need to know about carrying formula through airport security with you:
- Inform the TSA officer at the security checkpoint that you are carrying exempted liquids for your baby, such as baby formula or water (either cold water or hot water).
- Remove the exempted liquids from your carry-on bag and place them in a separate bin or bag as they will undergo additional screening.
- Tell the TSA officer about any non-exempt liquids in your carry-on, like your own water bottles. These must follow the 3-1-1 rule and go in a separate bag for screening.
- The TSA officer will likely perform additional screening procedures on the exempted liquids, such as opening the containers and conducting a swab test.
- After screening, you can proceed through the security checkpoint with the exempted liquids.
- Be sure to repack the exempted liquids securely in your carry-on bag before continuing with your travel plans.
It’s important to note that while the TSA allows exempted liquids for infants and toddlers, they may still perform additional screening procedures for security reasons.
To avoid delays or issues, arrive at the airport with enough time to go through the security checkpoint and pack your exempted liquids according to TSA regulations.

Tips for Traveling with Baby Formula and Water on a Plane
When traveling with baby formula and water on a plane, there are a few things to keep in mind.
Packing and Storing Baby Formula and Water for Travel
Here are some tips to make sure both are safe and secure:
1. Pack your liquids in a clear plastic bag.
2. Put that bag inside another bag to prevent leaks.
3. Put your formula and water in a separate container from everything else in your carry-on bag so you don’t accidentally spill them on other items.
4. Carry these liquids through security and prepare yourself!
Recommendations for Types of Bottles and Containers to Use
When traveling with baby formula and water on a plane, you must make sure you’re using the right type of containers and bottles.
The first thing to keep in mind is that you’ll want to use disposable bottles if possible. Ensure your reusable bottles seal tightly to prevent your formula from going bad. It’s also important to label each container with what it contains so that you can easily identify it should there be a leak or spill.
Don’t forget about the ice packs when packing your bottles and containers! These will help keep your formula cool throughout your trip.
Suggestions for Preparing Formula on a Plane
When traveling with a baby, having the right supplies is important. So what are some of the best ways to prepare formula and water for your baby on a plane? Here are three tips for doing so:
- Pack powdered formula in your carry-on bag. You don’t have to worry about it getting hot; if you’re flying in a window seat, you can keep an eye on it occasionally.
- Don’t forget the water! If you’re traveling with a baby who’s still breastfeeding, you’ll want to make sure that you have plenty of water available for her. Fill up several bottles in advance for ready use when needed. You can also order bottled water at the airport before boarding your flight. Just be sure it’s room temperature before giving it to your baby!
- Ensure you meet your child’s special dietary needs (like soy allergies) while flying!

Advice for Handling Spills or Leaks During Travel
Here are some tips for handling spills or leaks during travel:
1. Bring an extra bag of formula just in case your bottle spills. You can also bring multiple water bottles, so you don’t have to worry about running out if one spills.
2. Bring an extra change of clothes for yourself and your baby. If you’re traveling alone with your baby, this is especially important!
3. Store all liquids in plastic bags, not glass, and label them clearly as milk or breast milk. Bring them onto the plane with you.
To prevent contamination from items in your carry-on luggage or by TSA personnel, do the following. Store them separately and label them clearly, so officials know their contents.
Common Concerns and Questions
We know you have many questions, and we’d love to answer them. Here are some common concerns and questions we get from clients:
Can Parents Bring Ice Packs or Frozen Water for Formula?
The TSA regulation allows parents to bring ice packs and frozen water for formula, but only if the ice pack is completely frozen. It must be drained before being carried on a plane if it contains liquid.
Parents should be aware that TSA regulation officers will make sure all of the ice has been removed from the bag before allowing it through security. The bag will be tested for explosive residue if they do not remove enough.
Can Parents Bring Distilled Water, or Must It Be Bottled Water?
While it’s not recommended, parents can bring distilled water to the airport if they are flying with a child under two years old. However, it must be in a bottle, and the bottle must be less than 3.4 ounces.

How to Handle Connecting Flights with Different TSA Regulation?
If you are traveling from one city to another, or even on a long layover, and you have two flights with different TSA regulations, there are a few things you’ll want to consider.
First, if the first flight is domestic and the second is international, don’t worry! You can bring your electronics in your carry-on no matter what.
If the first flight is international but the second is domestic, this means that you will be going through customs when you land at your destination airport. The same rules apply keep your electronics in your carry-on luggage.
If both flights are international and there’s no customs checkpoint between them (for example, if they’re both going to Europe), then you can bring other belongings like any electronics with you in your checked luggage as well as in your carry-on baggage.
Time-Saving Tips with Ready-to-Feed Formula on a Plane
If you’re a frequent traveler or just seeking a more convenient way to feed your little one during flights, consider using ready-to-feed formula. Unlike powdered or liquid concentrate formula, ready-to-feed formula doesn’t require any mixing or measuring.
Ready-to-feed formula is pre-mixed baby formula that comes in bottles that are completely sealed and commercially sterile. When you’re ready to feed your baby, all you need to do is pop the top, attach a nipple, and give it to your baby. While it’s more expensive than powdered formula, the convenience could be worth the extra price, especially during travel.
TSA Regulation
Notably, TSA regulations classify ready-to-feed formula as a medically necessary liquid, meaning it’s exempted from the usual 3.4-ounce limit applied to carry-on liquids. So, you can bring it in containers larger than 3.4 ounces. However, remember to inform the TSA officers that you’re carrying ready-to-feed formula for additional screening.
Although it doesn’t need refrigeration, you may want to keep it cool during long trips. You can bring a cooler with ice packs, but remember that the ice packs need to be fully frozen when going through security. It may also be handy to bring a bottle insulator to maintain the right serving temperature once the bottle is opened.
Another advantage of ready-to-feed formula is reducing the chance of spills, which can be burdensome during flights. Since it’s pre-mixed, you don’t have to add water or powder, which significantly decreases the chance of any spillage.
However, just as with other types of formula, it’s vital to have a back-up plan in case of unexpected circumstances, such as travel delays. Also, bring extra sterile nipples and sanitized bottles to keep your feeding gear clean during travel.
Keep in Mind
Just keep in mind that once opened, ready-to-feed formula should be used within an hour, or you’ll need to refrigerate it and use it within 48 hours. If you are in doubt about the storage, adhere to the instructions provided on packaging.
Finally, before leaving for your trip, double-check the availability of your chosen ready-to-feed formula at your destination point, particularly if you’re traveling internationally. This is to ensure you won’t face any issues procuring your baby’s main food source while abroad.
So, amid myriad regulations and tips for traveling with a formula, ready-to-feed formula can offer parents an extra level of convenience and peace of-mind. Happy travelling!
