What is the main function of the Transportation Security Administration (TSA)?

The main function of the Transportation Security Administration (TSA) is to ensure the security of transportation systems, particularly those related to air travel. This encompasses a wide range of responsibilities, including screening passengers and baggage at airports, implementing security measures to prevent unauthorized access to restricted areas, and developing policies to safeguard transportation infrastructure. By focusing on security, the TSA aims to protect passengers, crew, and transportation assets from threats, which is crucial for maintaining public confidence in air travel.

In contrast, managing airport logistics, regulating flight schedules, or overseeing airport construction projects fall outside the TSA's core mission. These tasks are typically the responsibility of airport authorities, airlines, and other regulatory bodies, emphasizing that the TSA's primary role is security rather than operational or logistical management.
