Can Breast Milk Go Through Airport Security in the U.S.?
Before we even get into how breast milk is screened at TSA, some parents aren't always sure if they can even bring their breast milk supplies for their baby when they fly. Let's clear up these questions first by going over the TSA rules for flying with breast milk.
First of all, yes, breast milk is allowed on the plane, and even in your carry-on bag. It's considered a medically necessary liquid for your baby. Plus, it's exempt from the usual 3.4-ounce restriction on liquids, so you can bring as much as your baby needs!
However, you must always declare your breast milk supplies when you reach the security checkpoint.
What about international airports?
Well, not always. Rules can vary depending on the country and airport.
While the large majority of airports around the World follow the same rule as the TSA in the States, some international security checkpoints may have stricter limits or different inspection procedures. Check your destination airport's guidelines before you fly with breast milk to avoid surprises.

Is It Safe For Your Breast Milk To Go Through X-Rays at the Airport?
We know this is one of the biggest concerns for parents who are bringing pumped breast milk on their next flight. So, let's answer parents' most commonly asked questions about breast milk and the X-ray scanners at airport security.
- Can X-rays damage breast milk?
No. The X-ray machines used at airport security screenings do not harm breast milk.
These scanners use very low levels of radiation, far below recommended safety limits, and are designed to safely examine luggage without affecting its contents.
- Do X-rays affect milk quality in any way?
No. Studies and CDC guidance confirm that airport x-rays do not change the composition or quality of breast milk. Parents can rest easy that milk passed through security scanners is just as safe as it was before.
Whether your pumped milk is fresh, refrigerated, or frozen, it remains safe for your baby, with all its nutritional and immunological qualities preserved.
- What if I don't want my breast milk to go through the X-ray scanner?
Even though TSA X-ray machines are safe for breast milk, you always have the right to ask for an alternate screening if you'd rather your milk not go through the scanner. If you choose alternate screening, TSA may use methods like Explosive Trace Detection or Vapor Analysis instead of X-raying your milk.
You or your carry-on might get a bit of extra screening, like Advanced Imaging Technology or additional checks on other items, but at no point will your breast milk be exposed to anything that could compromise it.
How Can I Prepare to Take Breast Milk Through Airport Security Screening?
When flying with breast milk, preparation makes all the difference. Knowing how to pack your breast milk for travel and what to expect at the TSA screenings can help the process go smoothly and keep your milk safe. But maybe even more importantly, it helps reduce stress for you and your baby!
Here are a few tips:
✅ Use clear milk bottles or pouches so TSA officers can quickly identify the breast milk.
✅ Organize any breast pump accessories in one travel bag for easy removal if needed.
✅ Always carry your pumped breast milk in a travel cooler or mini fridge, making sure it's TSA-approved, like the ones from 4Allfamily.
✅ Arrive early. Give yourself a little extra time in case of additional screening.
✅ Let TSA officers know right away that you're traveling with breast milk.
✅ Be patient and calm. A polite, confident approach helps everything move more smoothly.
💡 Pro tip: Next time you take breast milk on a plane, label your milk with the date and volume. It shows you're organized and helps speed up the process.
