What function does the TSA primarily serve?

The Transportation Security Administration (TSA) primarily serves the function of ensuring security at transportation facilities, particularly at airports. This responsibility involves implementing strict security measures to protect passengers, crew, and airline operations from potential threats such as terrorism. The TSA conducts passenger screenings, baggage inspections, and monitors airport security to maintain a safe travel environment.

This focus on security is pivotal in managing the safety of the transportation system, supporting the overall goal of safeguarding the public as they travel. In contrast, managing airline operations, regulating ticket pricing, and providing customer service standards are functions that are more closely related to the airlines themselves or other regulatory bodies rather than the TSA.
