When should cabin service begin during a flight?

Cabin service should begin as soon as a safe walking attitude is reached because this ensures that the aircraft has ascended to a specific altitude where it is stable and safe for flight attendants to move about the cabin. This practice prioritizes the safety of both the passengers and the crew, as initiating service too early could lead to potential hazards if there were unexpected turbulence or the need for the crew to respond to in-flight situations.

Starting service after achieving a safe walking attitude allows flight attendants to manage the delivery of food, beverages, and other services effectively while maintaining safety protocols. In many cases, once this safe altitude is reached, and it is confirmed that the aircraft is stable, the flight attendants can commence with service in a organized and efficient manner.
