Flight attendants are essential members of an airline's crew, responsible for ensuring the safety and comfort of passengers during a flight. They conduct safety demonstrations, assist with boarding, and provide information about the flight. Their training includes emergency procedures, first aid, and customer service skills, allowing them to handle various situations that may arise in the air. In addition to safety, flight attendants serve meals and beverages, answer questions, and help passengers with any needs they may have. They play a crucial role in creating a pleasant flying experience, making travel more enjoyable for everyone on board the airplane.
