Know Your TSA Rights & Fly With Breast Milk - Mamava

Traveling with breast milk is officially less stressful. Thanks to the Bottles and Breastfeeding Equipment Screening Enhancement Act—better known as the BABES Enhancement Act—parents now have clearer protections when flying with breast milk, formula, and pumping equipment.

Passed in 2025, the BABES Enhancement Act strengthens the original 2016 BABES Act by requiring clearer TSA rules, better officer training, and more consistent screening nationwide. In short: fewer surprises at security and more confidence for breastfeeding parents.

Below is a streamlined guide to flying with breast milk and what this new law means for traveling parents.

What is the BABES Enhancement Act and how does it affect TSA screening?

The BABES Enhancement Act requires the TSA to:

• Publish clear, updated screening rules for breast milk, formula, baby food, and pumping equipment

• Train TSA officers consistently so policies are applied the same way at every airport

• Clearly communicate parents’ rights at security checkpoints

• Update guidance every five years to reflect new technology and family needs

Endorsed by organizations like March of Dimes, ACOG, MomsRising, and the Society for Maternal-Fetal Medicine, the law marks a meaningful improvement for breastfeeding parents who fly.

Can you bring breast milk through TSA security?

Yes—you can bring breast milk through TSA.

• Breast milk, formula, toddler drinks, and baby food are exempt from the 3.4 oz liquid rule

• These items are classified as medically necessary liquids

• Ice packs, freezer packs, and gel packs are allowed—even without milk present

• Your baby does not need to be traveling with you

Tip: Tell the TSA officer you’re carrying breast milk and separate it from other liquids to keep screening smooth.

Does TSA have to X-Ray or open breast milk?

You have options during screening:

• TSA recommends clear, translucent bottles when possible

• Frozen breast milk usually only requires a visual inspection

• Thawed milk may be tested for explosives—but you may decline

• You can request officers change gloves before handling your milk or pump parts

Are ice packs allowed when flying with breast milk?

• Ice packs and freezer packs are allowed in carry-ons

• They should be frozen solid when screened

• Slushy or melted packs may be subject to liquid restrictions

Reality check: TSA officers have final discretion. Heavy-duty ice packs last longer and reduce hassle.

How should you pack breast milk for TSA screening?

• Pack your pump, milk, and ice packs together in one bag

• Breast pumps are considered medical devices, but airline rules vary

• Always check your airline’s carry-on policy before flying

Pro tip: Bring a hand pump in your carry-on, because delays happen.

Where can you pump or breastfeed at the airport?

The free Mamava app helps you plan ahead by locating lactation spaces at airports and destinations.

• See photos, reviews, and amenities

• Get pod availability alerts

• Unlock Mamava pods and listen to soothing sounds to support letdown

Think of it as your pumping plan—handled.

What should you do if TSA questions your breast milk?

If screening doesn’t go as it should:

• TSA Cares (online)

• Phone: (855) 787-2227

• Federal Relay: 711

You’re protected by federal law, so don’t hesitate to speak up.

Does TSA PreCheck help when flying with breast milk?

• TSA PreCheck® can shorten lines and reduce stress

• Services like Milk Stork can ship breast milk home if you’d rather not travel with it

Can you fly internationally with breast milk?

Rules vary by country:

• United Kingdom: Up to 2,000 ml (67 oz) allowed in carry-ons if not frozen

• Canada: Breast milk is not limited by the 100 ml rule

Check rules before you fly and contact the American consulate for current guidance.

Can you ship breast milk across borders?

• Packing frozen milk in checked luggage is often simplest

• Shipping breast milk into the U.S. is legal for non-commercial use

• DHL and FedEx ship breast milk in many countries, but be sure to confirm locally
