How often should the lavatory be checked during a flight?

The correct answer is that the lavatory should be checked every 30 minutes during a flight. This frequency ensures that the facilities remain clean and operational for passengers, enhancing their comfort and overall experience. Regular checks help to manage waste, replenish supplies such as toilet paper and hand sanitizer, and maintain overall hygiene standards.

While checking the lavatory every 15 minutes might seem thorough, it could be excessive and may not be feasible depending on the aircraft size or the number of crew members available. Checking it every hour might lead to longer intervals between maintenance, which could compromise cleanliness and availability. Checking only at the beginning of the flight neglects the need for consistent oversight throughout the journey, which is crucial for passenger satisfaction and safety. Therefore, a 30-minute interval strikes a balance between thoroughness and practicality, ensuring that passengers have access to clean and functional lavatory facilities throughout the flight.
