Can You Bring Snacks On A Plane? Is it permissible to carry food on an aircraft? Whole fruit, granola bars, and sandwiches are among the solid foods that the Transportation Security Administration (TSA) allows to pass through airport security. But meals that are liquid or gel-like, like spreads, yogurt, or sauces, have to follow the 3-1-1 liquids rule. It's convenient to keep snacks in your carry-on bag, which will also guarantee that you have food for the duration of your flight. visit: https://bit.ly/3XEfXQU
