Major airline security agencies

Major airline security agencies include the Transportation Security Administration (TSA) in the U.S., which is responsible for screening passengers and baggage to ensure safety on commercial flights. Internationally, agencies like the International Civil Aviation Organization (ICAO) set global standards for aviation security. Airlines also have their own security teams that handle cockpit access and onboard safety. Additionally, airport security personnel manage perimeter security and access control. Together, these agencies work to prevent threats such as terrorism, smuggling, and sabotage, ensuring a safe travel environment for passengers and crew.
