You can bring most food through TSA, but your snacks, just like your toiletries, are subject to the 3-1-1 liquids rule. If they're considered a liquid, paste, or gel?a classification that isn't always obvious?they must be under 3.4 ounces.

There is no specific numerical limit on the number of solid snacks you can bring through TSA, provided they fit within your carry-on luggage allowance. You can pack as many bags of chips, granola bars, or sandwiches as you like. The critical restriction is the 3-1-1 rule, which applies to any snack that is a liquid, paste, or gel (e.g., yogurt, peanut butter, hummus, or salsa). These items must be in containers of 3.4 ounces (100ml) or less and fit into a single quart-sized clear bag. Solid foods like cookies, nuts, and fruit are generally green-lit without quantity restrictions. For a faster experience in 2026, TSA recommends grouping your snacks together in a clear bag and placing them in a separate bin for X-ray screening, as dense organic matter (like a large stack of energy bars) can sometimes trigger a manual bag search. Note that if you are flying from Hawaii or U.S. territories to the mainland, fresh fruits and vegetables are prohibited to prevent the spread of invasive pests.
