To attract the attention of a flight attendant (historically referred to as an air hostess) during a flight, the most appropriate and effective method is to use the overhead "Call Button" or to wait for them to pass through the cabin during their regular rounds. In 2026, cabin etiquette emphasizes respect and patience; you should never snap your fingers, whistle, or physically touch a crew member to get their attention, as this is considered highly rude and can even be flagged as "unruly behavior" in extreme cases. If you see a flight attendant in the galley, a simple "Excuse me" accompanied by a polite smile is the best way to initiate a request. Many frequent flyers find that returning a greeting during boarding or simply being polite when ordering a drink makes a huge difference; crew members are more likely to be attentive to passengers who treat them with professional courtesy. If you have an urgent medical or safety concern, using the call button is the standard protocol to ensure the crew is alerted immediately to your specific location without you having to leave your seat.
