Final answer:
Customers on international flights are typically offered water or juice every 1-2 hours, although this can vary based on the airline's service protocols and the flight's duration. The offering frequency may increase on longer flights to prevent dehydration and improve the passenger experience.
Step-by-step explanation:
On an international flight, the frequency at which customers should be offered water or juice can vary based on the airline's service protocols and the duration of the flight. Typically, flight attendants strive to offer beverages to passengers every 1-2 hours to ensure hydration and comfort. However, the actual frequency may also depend on the specific needs of passengers and any situational constraints, such as turbulence or other service considerations.
For longer flights, it's essential to maintain regular intervals as passengers may be asleep and miss earlier offerings. Airlines often encourage flight attendants to offer drinks more frequently on longer flights to prevent dehydration. Additionally, offering beverages regularly helps enhance the customer experience and is crucial for passenger health, especially in the dry cabin air.
In summary, there is no hard and fast rule but offering water/juice approximately every 1-2 hours is a standard practice on long-haul flights. Most airlines also make water available for passengers to serve themselves in between the service cycles.
