What is the immediate priority when a suspected security threat is identified on board?

• A. Continue service and monitor quietly
• B. Contact authorities after landing
• C. Take immediate action to restrain the suspect
• D. Inform the flight deck and purser, secure yourself and others, reassess the threat, and follow the established security procedures

Answer: (D)

When a suspected security threat is identified on board, the priority is to stabilize the situation and protect everyone by acting in a coordinated, controlled way. Inform the flight deck and purser so leadership is alerted and can initiate the appropriate security measures. Secure yourself and others to reduce risk and maintain order, then reassess the threat as the situation evolves. Following the established security procedures ensures the response is standardized and coordinated with any necessary authorities. Allowing the situation to continue unaddressed, waiting until after landing, or acting alone to restrain someone can increase risk or create confusion—this is why the coordinated approach of communication, self- and crew-protection, ongoing assessment, and adherence to procedures is the correct course.
