What should be checked before closing the aircraft door after confirming with the OPs agent?

Before closing the aircraft door, it is essential to check the door locks and seals to ensure that they are properly engaged. This is a critical safety procedure because if the door is not securely locked and sealed, it can lead to hazardous situations during taxi, takeoff, or flight. Ensuring that the door is properly closed helps to prevent any possibility of decompression or access to the cabin after the flight has commenced.

While checking emergency equipment, boarding documents, and passenger seating arrangements are important tasks in the overall safety and efficiency of flight operations, the specific focus on door locks and seals directly relates to securing the aircraft before departure. This step is vital in preventing potential safety issues that could arise from an improperly secured door.
