Which one of the following is a responsibility of a flight attendant during in-flight service?

The responsibility of ensuring passengers are comfortably seated is crucial during in-flight service. This task involves making sure that all passengers are securely fastened in their seats with seatbelts as required, particularly during takeoff, landing, and any periods of turbulence. Flight attendants play a key role in passenger safety and comfort, which includes guiding them to their seats, assisting with stowing luggage, addressing any passenger concerns, and providing reassurance about safety procedures. Comfort also extends to ensuring passengers have access to necessary amenities and service throughout the flight.

In contrast, delegating tasks to pilots is not within a flight attendant's responsibilities, as the pilot is the command authority in the cockpit and flight operations. Preparing the aircraft for arrival is predominantly the role of the flight deck crew and involves procedures critical to safe landing, which flight attendants assist with only in terms of passenger preparation. Monitoring weather conditions is also outside the flight attendant's scope of duties, as this task is overseen by the flight crew, who have the expertise and resources to assess and respond to weather changes affecting the flight path.
