When should flight attendants begin communicating updates to passengers regarding an ATC hold?

Flight attendants should begin communicating updates to passengers regarding an ATC hold immediately upon receiving hold information. This approach ensures that passengers are informed as soon as possible about the status of their flight, helping to alleviate anxiety and uncertainty. Timely communication is crucial in maintaining trust and ensuring a positive passenger experience, as it demonstrates that the airline is proactive in managing the situation and keeping passengers in the loop.

By informing passengers right away, flight attendants can manage expectations and provide important details that passengers may need, such as potential delays or changes in service. Quick communication also allows for any necessary preparations, such as managing cabin service or addressing any concerns passengers might have during the hold. This practice aligns well with the airline's commitment to customer service and safety.
