No, the TSA (Transportation Security Administration) is not privately owned; it is a United States federal government agency. It was created in response to the September 11, 2001, terrorist attacks and currently operates as a component of the Department of Homeland Security (DHS). While the TSA sets the national standards and provides the vast majority of airport screening personnel (over 50,000 officers), there is a small program called the Screening Partnership Program (SPP). This allows certain airports—such as San Francisco (SFO) or Kansas City (MCI)—to opt for private screening companies. However, even in those cases, the private companies must strictly follow all TSA regulations and are overseen by federal TSA managers. In 2026, the TSA remains a fully taxpayer-funded government body responsible for the security of all modes of transportation within the U.S., including airports, railroads, and mass transit, ensuring that the safety of the traveling public remains a public service rather than a profit-driven enterprise.
