What is the purpose of regular checks in the cabin by flight attendants?

The purpose of regular checks in the cabin by flight attendants is primarily to monitor activities and ensure safety. Flight attendants are responsible for maintaining a safe environment during the flight, which includes observing passenger behavior, ensuring that safety equipment is accessible and functional, and monitoring for any potential disturbances or emergencies. By conducting these regular checks, they can quickly identify and respond to any issues that may arise, thereby helping to ensure the safety and security of all passengers on board.

While other options may relate to aspects of a flight attendant's duties, the primary focus during cabin checks is on safety and security. Monitoring activities allows flight attendants to assess the overall condition of the cabin and intervene if any situation threatens passenger safety or comfort. This vigilance is critical, especially in the event of turbulence, emergency situations, or health concerns among passengers.
