The TSA's rules associated with carrying breast milk through security checkpoints are as follows: Moms flying with, or without, their child are allowed to bring breast milk in quantities greater than 3 ounces as long as it is declared for inspection at the security checkpoint.
Breast milk is in the same category as liquid medications.
When carrying breast milk through the checkpoint it will be inspected. However, you or your infant or toddler will not be asked to test or taste it. The TSA Security Officers have the right to test liquid exemptions (exempt items more than 3 ounces) for explosives.
When traveling with your infant or toddler, in the absence of suspicious activity or items, greater than 3 ounces of breast milk is permitted through the security checkpoint in reasonable quantities for the duration of your itinerary, if you perform the following:
- Separate the breast milk from the liquids, gels, and aerosols in your quart-size and zip-top bag.
- Declare you have breast milk to one of the Security Officers at the security checkpoint.
- Present the breast milk for additional inspection once reaching the X-ray. It is subject to additional screening.
- You are encouraged to travel with only as much breast milk in your carry-on needed to reach your destination.
Breast milk may be packed in your luggage and checked with your airline.
