What should flight attendants do in response to a passenger displaying red behaviors?

When a passenger displays red behaviors, which typically indicate a level of aggression, agitation, or a threat to safety, alerting a fellow crew member is the most appropriate action. This step is crucial because it ensures that the situation is assessed by multiple trained individuals who can collaborate on an appropriate response. Teamwork is vital in addressing potentially volatile situations while maintaining safety and security for all passengers and crew onboard.

By notifying another crew member, the flight attendants can effectively create a plan of action, whether that involves monitoring the passenger, implementing de-escalation techniques, or preparing to involve additional authorities if needed. This response reflects established protocols for managing unruly or disruptive behavior in aviation environments.

The other options fail to adequately address the urgency and seriousness of red behaviors. For instance, ignoring the behavior can lead to escalation and safety risks, while engaging the individual in conversation may inadvertently provoke further agitation. Requesting the passenger to leave the cabin is generally not feasible without proper authority and support, especially in the confined space of an aircraft. Therefore, alerting another crew member is a proactive and necessary response to ensure a safe environment.
