What could indicate a passenger is experiencing unmet expectations leading to disruptive behavior?

The indication of a passenger experiencing unmet expectations leading to disruptive behavior is best captured by the presence of anger or stress due to flight delays. When passengers have specific expectations regarding travel, such as timely departures and arrivals, and these expectations are not met, it can lead to significant frustration and agitation. Flight delays disrupt the flow of a passenger's plans and can exacerbate feelings of anxiety or anger, prompting disruptive behavior during the travel experience.

Timely performance by the airline and positive interactions with staff generally contribute to a sense of satisfaction and alignment with passengers' expectations, reducing the likelihood of disruptive behavior. Compliments about airline services would indicate satisfaction rather than unmet expectations. Therefore, recognizing signs of distress, like anger or stress due to delays, is crucial for addressing potential disruptions effectively.
