Can You Bring Milk on International Flights?

The TSA answer about taking  milk on international flight

The TSA regulates only what you can take on flights within and from the United States.

And because raw milk can carry harmful germs, some countries will not let milk or dairy products enter their territories, so taking milk on international flights will depend mostly on where are you heading.

Before you fly, ensure that you have a bit of an idea about the country of your destination customs, and whether they permit dairy products or not.

For example you can bring liquid milk and milk products intended for use by infants to the United States but in reasonable quantities.

But you can’t take milk or milk-based products to the UK from countries outside the European Union.

Final Thoughts 

Attempting to take a gallon of milk through airport security without following the proper procedures is not a good idea.

Only smaller containers of milk are permitted in carry-on baggage if you are not traveling with an infant.

Traveling with milk for infants and toddlers is easy and can be done smoothly as you can take as much as you will need for your trip, if you are traveling internationally it is better to contact your airline, use an insulated container, and store milk in a separate bag.
