If you're planning to bring a food item for dinner, WIVB reports that many foods are allowed through a Transportation Security Administration (TSA) checkpoint, but some may need to be checked with your luggage.

If it’s a solid item, then it can go through a checkpoint. However, if you can spill it, spread it, spray it, pump it or pour it, and it’s larger than 3.4 ounces, then it should go in a checked bag. -WIVB

Often, a food item will require extra screening, so to make that easier, the TSA recommends placing those items in a clear plastic bag or another clear container. Then you can remove those items from your carry-on bag and put them in a bin for screening at the checkpoint (like you would with laptops).

Travelers who are unsure if an item should be packed in a carry-on or checked bag can check the TSA homepage, which has a helpful “What can I bring?” feature. Type in the item and find out if you can carry it through a checkpoint or if it should be checked. Another option is for passengers to tweet to @AskTSA to ask how best to travel with a specific food item. -WIVB
