Traveling with food on domestic flights can be confusing, but knowing the regulations can make your journey smoother. Most airlines allow you to bring food through security as long as it meets TSA guidelines. Solid foods like sandwiches, fruits, and snacks are generally permitted, but liquids and gels must adhere to the 3-1-1 rule: containers must be 3.4 ounces or less, and all items must fit in a single quart-sized bag. Always check with your airline for specific policies. For a hassle-free experience, pack food in compliance with security rules and be prepared for possible inspections at the checkpoint.
