Tips For Flying With Breast Milk

Transporting breast milk can be made easier and less stressful with a bit of knowledge and understanding of airport policies.

Discover all the tips for flying with frozen breast milk, chilled breast milk and the rules so you don’t get caught out.

As an ex flight attendant, I’ve helped other parents travel as well as flown with my own babies many times long haul internationally. I’ve breastfed, pumped and formula fed, so a real mixture!

We break this down step by step below, but most of the rules:

  • Depend on the country you are flying out of.
  • Whether your infant is traveling with you or not.
  • Not every country will allow you to travel with frozen breast milk in carry on bags, in your checked baggage or both!
  • An exception is the USA who will allow you to travel with frozen breast milk in all the above scenarios.

Frozen breast milk aka liquid gold!

Frozen breastmilk is still considered a liquid when flying by some countries, so occasionally, the same airport rules regarding liquids apply. This usually applies if your baby is NOT flying with you, in which case you must follow the normal liquid rules.

Thankfully, some countries like the USA, realise that a working mom will likely be away from her child and need to pump, and bring back frozen breastmilk without having her child with her! 

We detail some of the countries which allow plane travel with frozen breast milk in the cabin as carry on luggage and some that don’t in the table below.

Dry Ice is a dangerous good and one of the things asked at check in. It can be used in small quantities in some circumstances to keep breast milk frozen.

Dry Ice Policies

Air travel with breast milk requires an ice pack or dry ice (a dangerous good) to keep it frozen but not all airlines allow dry ice. There is no one answer to cover all countries so the rules may be different on your return trip.

Another consideration is whether you can bring dry ice into the aircraft cabin as well as the hold. Whilst airports have their own policies about what they will allow through to the boarding gate via security, and the International Air Transport Association (IATA) DO permit up to 2.5kg per passenger (under certain conditions), it is ultimately up to the individual airline whether they will permit items such as dry ice into the cabin. if in doubt, check with your airline and get it in writing.

In all cases, when flying with frozen breast milk and dry ice, do check with your airline in advance, print out the policies for the airlines and relevant aviation authorities, emails (see the below chart for details) and all other relevant paperwork.

Always allow extra time at the airport. Passengers travelling with dry ice in the cabin, is not a common procedure for many airlines, so they may need to double check with seniors or manuals to verify the process.

The easiest way to transport frozen breast milk, is by using an ice pack and avoiding the extra paperwork that dry ice entails.

Below are airport security regulations to help you plan air travel with breast milk.

I approached the airports and airlines directly for this information via email. Be aware that countries policies vary greatly, so don’t be caught out!

Before you fly, go through the below questions so you can check with the airport/country policy for transporting frozen breast milk and chilled breastmilk as carry on and/or checked baggage.

Traveling with Frozen Breast Milk Considerations:

  • Is there a limit to the amount of breast milk you can travel with?
  • What watertight containers or coolers will you use to transport your breast milk?
  • Is the frozen breast milk allowed as carry on?
  • Do I need my baby with me if I bring frozen carry on breast milk?
  • Will your airline/airport allow dry ice or ice packs? Do they need to be frozen solid or are gel packs allowed? If neither use a Ziploc bag and fill with ice cubes which are easy to replenish at the airport and on the plane.
  • Where can I pick up/purchase dry ice?

Airport regulations for flying with breastmilk

ALL American airports rules for flying with breastmilk

The rules for flying with breast milk remain the same whether your infant is accompanying you or not. Formula, breastmilk and juice in qualities greater than 3.4 ounces or 100ml are allowed in carry-on baggage and do not need to fit within a quart sized bag.

Formula, breast milk, toddler drinks, and baby/toddler food (to include puree pouches) are considered medically necessary liquids.

This also applies to breast milk and formula cooling accessories, such as ice packs, freezer packs, and gel packs (regardless of presence of breast milk).

Please pack these medically necessary liquids in a way you can present them for inspections at the check point. Please inform officers of your medically necessary liquids and place them in a separate bin from your other items.

 ALL Australian airports rules for flying with breastmilk

Domestic flights

There are no restrictions on the amount of liquids and gels you can take onboard a domestic flight for a baby or infant. However, if you are connecting to an international flight or if your domestic flight is departing from an international terminal, limits apply.

What is a reasonable quantity?

Security screening officers have the final say about a ‘reasonable quantity’. You may need to surrender some of your baby items if it has been decided that it is an excessive quantity of inorganic powder, liquid, aerosol or gel items for the flight.

If travelling without a baby

Passengers travelling without their infant or toddler may only take expressed breast milk onboard an aircraft in containers of 100 millilitres or less and no more than one litre in total. It must be contained in a transparent, re-sealable plastic bag where the four sides add up to no more than 80 centimetres (e.g. 20×20 cm or 15×25 cm).

This is governed by international regulation (ICAO). While technology and processes used may vary from airport to airport, all liquids and gels must be screened and their state, quantities, temperature, packaging etc. controlled.

Some of these international regulations are paraphrased/outlined below (although please check with ICAO and/or IATA to confirm).

  • The passenger must declare the nature of any carried liquid to the airport security and airline.
  • The airline is responsible and must agree to carry any liquids.
  • The temperature of carried liquid is also regulated, so a small variation can affect the screening process. (E.g if it is a frozen solid.)
  • The hygiene of the liquid must remain undisturbed.

How to Travel with Frozen Breast Milk

How to Transport Breast Milk

Whether you are traveling with breast milk internationally or domestically you first need to check the rules.

The best place is either the website of the airport you are flying out of, or your government website travel section. eg TSA breast milk rules can be found here.

Once you have worked out whether you are allowed to transport frozen breast milk, if it’s allowed in the cabin or checked luggage, then you need a good method to keep your breast milk either frozen or well chilled.

When traveling, the best coolers for breast milk are well insulated, easy to carry, lightweight with adequate space.

How to Keep Breast Milk Frozen While Traveling

These tips are based on you be allowed to use ice packs and travel with frozen breast milk. Traveling with frozen breast milk involves a little bit of preparation beforehand, including checking if you have additional forms to fill in and adequate storage.

A well insulated breast milk cooler bag works best when you leave it sealed and minimise any opening. make sure you have enough ice packs or have obtained special permission to use dry ice. See the best travel coolers for breast milk here.

  • Make sure the milk is well frozen when packing – if it starting to defrost, it may not be allowed.
  • Make use of all available space in the cooler – all those frozen milk packs are ice blocks themselves so make sure the cooler is as full as possible!
  • Use plenty of ice blocks or ice packs and pack the entire contents as tightly as possible.
  • Make sure container seals well and is insulated.
  • Label the containers well
  • Make sure all documentation is ready and printed out
  • Be prepared that security may want to open your container and test a packet. This shouldn’t take too long and the milk will stay frozen for that short time.

Frequently Asked Questions

Can I fly with frozen breast milk?

Usually as checked baggage yes. For carry on it depends on the country rules and regulations you are flying from.

Check some country regulations here:

Do I have to travel with my baby to fly with breast milk?

No, BUT, and it’s a big but, not all countries will allow parents to travel with additional liquids (even if breastmilk) without their baby, meaning you would need to adhere to the 3-1-1 /100 ml liquid rule for carry on liquids. For checked baggage, larger liquids are allowed in all circumstances but frozen rules differ. When traveling domestically from the US you are able to travel with breastmilk without baby with no issues. Flying internationally out of the USA the TSA advises that you can travel without your baby.

How much breastmilk can you bring on a plane?

This depends on whether you are planning on bringing in the cabin or the hold or both. If you have baby with you, and it’s liquid, you can bring as much as you need for the journey or a ‘reasonable quantity‘ as carry on luggage with all airlines. With most airlines you can bring it on as checked luggage. However, if bringing it on the plane as frozen for carry on, this will depends on individual country rules. It will likely need to be inspected at security.

How do you pack frozen breast milk in checked luggage?

See above, section on How to Keep Breast Milk Frozen When Traveling.

Can I use dry ice to travel with my frozen breast milk?

This is usually up to individual airlines. So check with your airline first. Additional paperwork and labelling is needed for traveling with dry-ice as it is a dangerous good.
