When preparing for air travel, understanding the Guidelines for Bringing Tools on Flights is crucial to avoid complications and ensure a smooth journey. The Transportation Security Administration (TSA) and other aviation authorities have specific rules regarding what tools can be carried in your carry-on luggage versus your checked baggage. Generally, small hand tools like screwdrivers, pliers, and wrenches can be packed in checked bags but are often restricted in carry-ons due to security concerns. Tools with sharp edges or those that could be used as weapons are usually prohibited in the cabin.
