Can you bring cereal through airport security in your carry-on baggage?

Yes, the Transportation Security Administration (TSA) will allow you to bring dry cereal through airport security in your carry-on baggage. Any type of dry cereal is typically fine, including packaged cereals, rolled oats, and store-bought or homemade granola. If the cereal is no longer in its original packaging, it should be placed in a resealable bag or container with a secure lid. There is no limit to the quantity of dry cereal you can bring in your carry-on: You can pack as much cereal as you’d like and will fit into your allowable hand luggage.

Can you bring milk for your cereal through airport security?

Unless it’s for an infant or a toddler, you can only bring a very small quantity of milk through airport security to go along with your cereal. Milk falls under the TSA’s “3-1-1 liquids rule”, which requires that all liquids and gels in your carry-on luggage be stored in 3.4-ounce or smaller containers, all of which must fit into one quart-sized plastic bag. Once you have passed through the TSA checkpoint and are in the secure area of the airport, however, you can purchase a larger-sized container of milk and bring that on board in your hand luggage.


Can you bring cereal on an airplane in your checked baggage?

Yes, you can bring cereal in your checked baggage when boarding a flight within the United States. You can bring as much cereal as you’d like in your allowable checked luggage.


Can you bring cereal on an international flight leaving the U.S.A.?

Yes, you can bring dry cereal on an international flight departing from the U.S., either in your carry-on baggage or your checked luggage. If your intention is to bring the cereal onto the plane in your carry-on baggage and eat it during the flight, you’ll have no issues. The TSA applies the same rules for allowing cereal through security at U.S. airports, whether you are flying domestically or internationally.

You can also bring cereal into many foreign countries. But depending on the country, it may have to be in its original packaging and unopened. Be sure to check your foreign destination’s rules before leaving.



Can you bring cereal on an international flight back into the U.S.A.?

Yes, the United States generally allows travelers to bring cereal into the U.S. when arriving on a flight from a foreign country.

Note that even though cereal is typically allowed, you must declare all foods that you bring into the United States — whether they are allowable or not — to U.S. Customs and Border Protection (CBP). The penalties for failing to declare your food items can be steep; bear in mind also that the CBP routinely conducts random screenings for arriving passengers.



Commercially packaged cereal will generally keep well for about 2 to 3 months after opening when stored at room temperature.


Note: While the above information is based on applicable Transportation Security Administration (TSA) and U.S. Customs and Border Protection (CBP) guidelines at the time of publication, the final decision for whether to allow a food item through airport security or into the United States rests with the TSA and CBP officers on duty at the airport. Regulations also change frequently: For the latest information, check the US Customs and Border Protection and Transportation Security Administration websites.
