How should a flight attendant behave in the case of a lengthy tarmac delay?

A flight attendant should remain calm and assist passengers during a lengthy tarmac delay because this behavior fosters a sense of security and support in what can be a stressful situation. Providing assistance includes informing passengers about the situation, offering reassurance, and addressing their needs, which helps to maintain a positive environment. Maintaining composure helps to de-escalate any anxiety among passengers and reinforces their trust in the airline's commitment to their well-being. It is crucial for flight attendants to play an active role during such delays, as their interaction can significantly impact the overall experience of passengers during times of inconvenience.
