If a customer is calling from the lavatory, what color is the indicator light?

In the context of United Airlines standard operations procedures, if a customer is calling from the lavatory, the indicator light is amber. This color is specifically designated to indicate that the lavatory is occupied and that any calls made from that location will be difficult to manage immediately. The amber light serves as a clear signal to the flight attendants and crew that the space is in use, helping to maintain privacy for the customer and allowing the crew to make informed decisions regarding customer service needs and safety.

The choice of amber for the lavatory indicator light is important for operational flow; it communicates occupancy without suggesting an emergency or urgent situation that might be indicated by a red light. Understanding this signaling can be crucial for both customer experience and crew coordination on a flight.
