Flight attendants are responsible for knowing where the safety equipment on board is located, how to use it, and in which scenarios to use what. They help accommodate passengers as they board the plane, and must report any dangerous materials they spot, or unusual smells. Flight attendants instruct passengers on safety and emergency protocols, including how to use their seat belts, oxygen masks, and which exist are designated for evacuation. Before the plane takes off, they ensure that trays, baggage, and other items are secured. While the plane is in flight, attendants are responsible for maintaining a safe and peaceful environment on board, serving food and drink to the passengers, and addressing any concerns they might have. This is why good customer service and hospitality skills are encouraged for those looking to join an airline’s cabin crew.
