Which of the following is not a duty of flight attendants during service?

The role of flight attendants encompasses a variety of duties focused on ensuring passenger safety and comfort during the flight. While they do engage with in-flight entertainment systems, monitoring them is typically not classified as a core duty during service.

Taking meal orders, serving beverages, and cleaning the cabin are integral parts of a flight attendant's responsibilities. They are trained to interact with passengers directly regarding meals and service and to maintain cleanliness in the passenger area to enhance the overall flight experience. Although flight attendants may assist in troubleshooting in-flight entertainment if issues arise, actively monitoring these systems generally falls outside their primary service duties. This distinction helps clarify the focus of their responsibilities on passenger care and safety.
