Airport security is a set of procedures designed to ensure the safety of passengers and aircraft. It typically includes screening of passengers and their luggage for prohibited items, such as weapons and explosives. Security personnel use various technologies, including metal detectors and X-ray machines, to identify potential threats before boarding. In addition to screening, airport security involves the presence of trained staff, including TSA agents in the United States, who monitor the airport environment. They may conduct random checks and maintain a visible presence to deter suspicious activities. These measures help create a safer travel experience for everyone.
