When should cabin crew demonstrate the oxygen masks and life vests during the flight?

Cabin crew should demonstrate the oxygen masks and life vests prior to reaching 25,000 feet and also after flying over water. This practice is crucial for passenger safety, as it ensures passengers are aware of how to use these safety devices in the event of an emergency.

Demonstrating oxygen masks before reaching 25,000 feet is essential because the cabin environment may change due to altitude, making it important for passengers to understand how to properly use the masks in case of a sudden drop in cabin pressure. Additionally, informing passengers about life vests after take-off, particularly when flying over water, provides them with vital information about how to stay safe in the unlikely event of a water landing.

This comprehensive approach to safety demonstrations allows cabin crew to effectively prepare passengers for various emergency scenarios throughout the flight.
