Yes, you can absolutely pack food in your personal bag when flying in 2026, provided it follows the TSA's "Solid vs. Liquid" rules. Most solid foods—such as sandwiches, fruit, nuts, pizza, and even cooked meat—are perfectly fine to carry through security. However, any food that is "spreadable" or "pourable" is treated as a liquid. This includes peanut butter, yogurt, hummus, salsa, and jams, which must be in containers of 3.4 ounces (100ml) or less and fit inside your single quart-sized clear bag. If you are traveling with a baby, "medically necessary" items like formula, breast milk, and baby food are exempt from these size limits, though you must declare them for manual screening. A "pro-tip" for 2026 travelers: pack your snacks in a clear container or bag within your personal item; this makes it easier for security officers to see what you have, reducing the chance of your bag being pulled for a time-consuming manual search.
