As you’re packing up for your trip, you might need milk to care for your infant or toddler. Or maybe you’re just wondering if you can bring it on a plane for yourself.

How to Pack Milk in Carry-On

When you go through airport security, you may need to set aside your milk for a separate screening. It’s best to pack it in a sealed, labeled container to make screening quick and easy. The container must be able to fit into a quart-sized bag.

Sometimes, items can obstruct the x-ray machine making it difficult for TSA agents to screen your luggage. So it’s best to pack your milk separately to minimize delays at the security checkpoint.

If your milk is for childcare, then it doesn’t follow the TSA’s 3:1:1 rule. Make sure that the TSA agents know this when you go through screening. With baby formula, milk or any other drink for infants, you can bring as much milk as needed. But make sure it’s a reasonable quantity.

In other words, only bring on as much as you need. Don’t try and get past the TSA checkpoint with several gallons. You’ll likely end up exceeding the weight limit of your carry-on luggage, as liquids are quite heavy. You may be subject to additional screening too. TSA agents reserve the right to confiscate your belongings if they violate their policies.

What is the TSA’s 3-1-1 rule?

The 3-1-1 liquids rule is a rule implemented by the Transportation Security Administration (TSA) that regulates how much liquid you can bring on a plane. This rule states that you can bring up to 3.4 ounces or 100 mL of liquid on a plane. All of your liquids must be in separate containers of 3.4 ounces or less. And they must fit in one quart-size bag. 3.4 ounces, 100 mL, one quart-size bag. Hence, 3-1-1.

The 3-1-1 liquids rule can be misleading because not all the items that follow this rule are technically liquids. It also applies to gels, aerosols, creams, and anything in between. Here’s what @AskTSA has to say about the rule.

You won’t be able to bring more liquid than whatever will fit in the quart-size bag.

Frequently Asked Questions

  1. Pass the item to a friend who’s not traveling.

Recap and My Recommendations

You can bring milk on a plane. Just make sure that you follow the TSA’s rules and regulations.

Keep in mind that milk may be subject to additional screening at the security checkpoint. You can take it in your checked baggage to avoid that hassle. If the milk is for your child, be sure to tell the TSA agent.

If your milk is for your baby and you are bringing your baby on a plane, definitely bring it on board. Or if you need it for a medical reason, take it with you on the plane. Otherwise, keep it in your checked baggage. Milk can take up space you might need for other items. You might want space for electronics or books to keep you entertained in flight.

You could also buy milk once you get to your destination. Then you don’t have to worry about getting through security or leaving enough space for milk in your carry on. It just makes your life a little easier.
