Who is responsible for advising if deplanement is required using a bridge or stairs?

The flight crew is responsible for making the decision regarding whether deplanement is required using a bridge or stairs. This is because the flight crew has comprehensive knowledge of the safety protocols and conditions surrounding the aircraft upon landing. They assess the situation, including the operational status of the aircraft, potential safety hazards, and the availability of ground services.

In normal circumstances, the cabin crew works in coordination with the flight crew to ensure that passengers are deplaned safely and efficiently while adhering to any necessary regulations or procedures. The flight crew's authority and training equip them to evaluate the safest way to facilitate the deplanement process.

This responsibility typically does not fall to passengers, as they rely on the crew to guide them. While the ground crew may assist in the deplanement process by providing the necessary equipment and support, the final decision-making rests with the flight crew. Airport management is involved in broader operational aspects but does not usually dictate deplanement methods directly.
