TSA also says that you don’t have to put the cooking sheets up if you plan on flying! You can still spend time baking your favorite Christmas cookies, fruitcake, pie or other holiday treats. If the food item is a solid (ham, turkey, cake, pie, cookies, etc.), then you can pack it in your carry-on bag. If the food item is spreadable or pourable, then it must be 3.4 liquid ounces or less to comply with the 3-1-1 liquids bag rule to travel in your carry-on bag. If it has more than 3.4 liquid ounces, then you should pack it in a tightly sealed container in your checked bag. If you’re unsure if your food item should go in a checked bag, consider this: If you can spill it, spread it, spray it, pump it or pour it, then please pack it in your checked bag.
