What should passengers be reminded to do while seated and after the fasten seat belt sign is off?

Passengers should be reminded to keep their seat belts fastened even after the fasten seat belt sign is turned off. This is important for safety during unexpected turbulence, which can occur without warning. Keeping the seat belt fastened provides additional protection for passengers in case of sudden movements of the aircraft, enhancing their safety throughout the flight.

Removing seat belts might lead to unnecessary risks, especially if the aircraft encounters turbulence. Allowing passengers to move around the cabin could also increase the likelihood of accidents or injuries. Preparing for landing is typically not relevant until the aircraft is closer to its destination, and at that point, announcements and instructions typically inform passengers about what to do. Thus, maintaining a fastened seat belt is the best practice for passenger safety during the flight.
