What Can I Bring With Me on a Plane, it's essential to know what items you can bring on board to ensure a smooth security check and comfortable journey. Passengers are generally allowed to bring personal items such as clothing, electronics, and reading material. However, specific restrictions apply to liquids, gels, and aerosols, which must be in containers of 3.4 ounces (100 milliliters) or less and packed in a single, clear, quart-sized bag. Sharp objects, firearms, and other potential weapons are prohibited in carry-on luggage but may be allowed in checked bags under strict regulations. Medications, baby formula, and food for special dietary needs are typically permitted but should be declared at security checkpoints.
