Foods You Can (and Can't) Take Through TSA Security
General TSA Food Rules
A good rule of thumb when it comes to packing food in your carry-on luggage is that solids are usually fine, and liquids, spreadables, or gels are also permitted but cannot exceed 3.4 oz. The TSA calls it the 3-1-1 rule, allowing 3.4 oz or 100 ml of these items that all must be contained in one quart-size clear plastic bag.
How to bring liquid or spreadable items through security checkpoints
When deciding what to bring on a plane, measure, measure, measure. Anything that’s a liquid, gel, or spreadable is subject to the 3.4 oz rule. Before your trip, purchase some TSA-approved 3.4 oz containers that are clearly marked and prioritize what you actually need.
Just because you’ve packed or poured everything into appropriately-sized containers doesn’t mean you won’t run into trouble. Even the 3.4 oz containers have a limitation. Each passenger is allowed one quart-sized clear plastic bag in which to put their liquids and gels. This amounts to roughly 9 containers. So don’t go crazy!
