What is a common responsibility of the Transportation Security Administration (TSA)?

The Transportation Security Administration (TSA) has a primary focus on ensuring the safety and security of the traveling public in the United States. This responsibility includes implementing and enforcing security measures for air travel, which encompasses screening passengers and their belongings at airports, deploying security personnel, and establishing protocols to prevent potential threats to aviation security.

The TSA's role is crucial in maintaining a secure environment for air travel, which has been a top priority since the events of September 11, 2001. This involves regular updates and adjustments to security protocols in response to evolving threats, and collaboration with various agencies to enhance the effectiveness of security measures across the transportation network.

The other options relate to aspects of the airline industry but do not fall under the TSA's purview. For instance, developing airline loyalty programs is primarily the responsibility of airlines themselves, while managing passenger baggage policies and regulating airline ticket prices are typically handled by airline companies and the Department of Transportation, respectively. Thus, the correct answer accurately reflects the TSA's core function in air travel security.
