If a cabin crew hears a comment about a bomb on board, what is their immediate responsibility?

When a cabin crew hears a comment about a bomb on board, their immediate responsibility is to advise the flight crew, who are trained and equipped to handle such serious security threats. This response is vital because the flight crew will then take appropriate action, which may include informing ground personnel and coordinating safety procedures to ensure the safety of all passengers and crew members.

The priority in this situation is to escalate the matter promptly, as it is a potential threat that requires immediate attention. The flight crew is positioned to assess the situation further and communicate with authorities on the ground. Following these protocols helps maintain order and ensure a thorough and efficient response to any security threat.

While it might seem reasonable to want to calm passengers or search for the bomb, these actions could put crew members and passengers at greater risk or hinder the professional response required in such a high-stakes situation. Ignoring the comment would also be inappropriate in light of the severity of the matter.
