A cabin crew website recently explored the appropriateness of pressing the flight attendant call button, revealing varying responses based on airline, flight phase, and class of service. Asian or Middle Eastern carriers generally accommodate such requests, while U.S.-based attendants often disapprove.
The timing of the request is crucial. During taxi, takeoff, and landing, cabin crew cannot fulfill drink requests due to safety protocols. They are also occupied during boarding and meal services.
Class of service also influences response; business class passengers typically receive more favorable treatment than those in coach.
