Flight crews are teams of professionals responsible for ensuring the safety and comfort of passengers during a flight. They typically include pilots, who operate the aircraft, and cabin crew, who assist passengers and manage in-flight services. The cabin crew consists of flight attendants who provide safety instructions, serve meals, and respond to passenger needs. They are trained in emergency procedures and first aid to handle any situations that may arise during the flight. Together, the flight crew works to create a safe and pleasant travel experience for everyone on board.
