What items are prohibited in carry-on bags?

The Transportation Security Administration, often abbreviated as TSA, maintains a comprehensive list of items that are prohibited in carry-on bags to ensure the safety and security of all passengers during air travel. These prohibited items generally include any items that could potentially serve as weapons or pose a risk to the safety of the flight and individuals on board. For example, sharp objects such as knives, scissors, and razor blades are not allowed in carry-on luggage. Tools such as hammers and drills are also prohibited. Additionally, sporting goods that could be used as weapons, including baseball bats, golf clubs, and hockey sticks, cannot be carried onto an aircraft. Furthermore, the TSA prohibits flammable items in carry-on bags. This category includes lighters, matches, and any type of gasoline. Explosives or explosive materials, including fireworks, are strictly banned as well. Another important area of concern is liquids and gels. The TSA has specific regulations governing the transport of these items. Passengers are generally limited to carrying liquids, aerosols, gels, creams, and pastes that are in containers of no more than 3.4 ounces (100 milliliters), and all containers must fit into a single quart-sized clear zip-top bag. It is advisable for travelers to check the most current information available on the TSA's official website, as regulations may evolve over time. The website offers detailed guidelines and updates that can help ensure a smooth security checkpoint experience.
