How Much Breast Milk Can You Take On An Airplane?

As if the frustrations of air travel weren't bad enough, the Transportation Security Administration (TSA) has restrictions on how much liquid you can take with you through their airport security checkpoints. Of course, this is for everyone's safety as liquid explosives pose a serious threat to aircraft carriers. Here's the good news, though. However annoyed you are that you have to toss your Poland Spring 16-ouncer, your breast milk is good to go.

The TSA's Screening Of Liquids Greater Than 3.4 Ounces (100 ml)

Typically, the TSA only allows liquids to be carried onto an airplane if they are in containers 3.4 ounces (100 ml) or less, and all the containers fit into one clear quart-sized zipper bag.  However, the liquid rule is a little different when it comes to feeding infants and children. This is the category that breast milk falls into. 

Moms flying with, or without, their child are allowed to bring breast milk in quantities greater than 3.4 ounces or 100 milliliters as long as they declare it for inspection at the security checkpoint. The TSA Security Officers will examine your containers, and they have the right to test all liquids for explosives. So, when carrying breast milk through the security checkpoint, it will be inspected, but you or your infant or toddler will not be asked to test or taste it. 

How To Travel With Breast Milk Through The Airport Security Checkpoint

When traveling with your infant or toddler, in the absence of suspicious activity or items, you can bring your breast milk through the TSA's airport security checkpoint if you perform the following:

  • Separate your breast milk from all the other liquids, gels, and aerosols in your carry-on bag.
  • Tell the security officer at the security checkpoint that you have breast milk to carry on to the airplane.
  • Once you reach the X-ray machine, have your breast milk out and ready for additional inspection. The FDA has stated that foods or medications that have been through the X-ray machine are not harmful.

Liquids In Your Checked Luggage

You should bring the amount of breast milk and formula that you will need for the duration of your flight in your carry-on bag. Any additional breast milk or formula may be packed in your luggage and checked with your airline.
