If you don't frequently travel by plane and have a trip coming up, you may be wondering: Can you bring food on an airplane? In most cases, yes, you can bring food with you. What’s more, you don't necessarily have to buy food at the airport or wait until you get to your destination to buy it.

Here's what you need to know about the general rules for flying with food.

Can you pack food in a checked bag?

Yes, you can bring food in your suitcase on an airplane — but there are some exceptions to consider. The Transportation Security Administration has several rules in place and knowing what's allowed before arriving at the airport can help you better prepare. Here are the essential TSA food rules for checked luggage.

Solid food items

You can bring solid food items in your carry-on bag or checked luggage without adhering to size restrictions. Of course, bag and weight restrictions apply, and if your item is larger than allowed, you may have to pay extra fees.

Liquid and gel food items

In general, TSA liquid food rules are more strict. Liquid and gel food items are treated like liquid and gel toiletries — and the same rules apply.

All liquid or gel food items above the 3.4-ounce maximum liquid carry-on size requirements must be packed in your checked baggage; otherwise, they won't be allowed past the security screening process.
