Who is responsible for closing the boarding door during normal operations?

In typical airline operations, the responsibility for closing the boarding door during normal operations falls to the Customer Service Representative. This role primarily involves managing the boarding process, ensuring that all passengers have boarded, and that the aircraft is prepared for departure. They follow established protocols for safety and efficiency, which includes closing the boarding door once all passengers are accounted for.

The captain and first officer are primarily focused on the safety of the flight and the operation of the aircraft, including controlling flight systems and managing cockpit operations. Their duties typically do not include handling passenger boarding procedures directly.

Flight attendants are tasked with passenger safety and service during the flight, but the responsibility for managing the boarding process, including the closing of the door, is typically designated to the Customer Service Representative or gate agents before the aircraft pushback.

This delineation of responsibilities ensures that each crew member focuses on their specific tasks, which is critical for maintaining efficient operations and passenger safety.
