What should a flight attendant ensure toward the end of service at almost 10,000 feet?

Ensuring that the cabin and galleys are secure toward the end of service at almost 10,000 feet is essential for the safety and well-being of everyone on board. At this altitude, the flight attendant's responsibilities shift to preparing for potential landing procedures and maintaining a secure environment.

By confirming that all items in the cabin are stowed properly and that the galleys are organized, the flight attendant helps minimize the risk of injury during turbulence or when preparing for descent. This task is a crucial part of ensuring that the aircraft operates safely and efficiently as it prepares for landing.

While preparing for landing procedures may involve securing the cabin as well, the specific focus on confirming that everything is secure ensures readiness for a safe landing approach. Therefore, ensuring the cabin and galleys are secure is the most immediate and critical responsibility at this stage of the flight.
