Briefly describe the duties of a lead flight attendant.

The duties of a lead flight attendant primarily focus on overseeing and supervising the cabin crew to ensure a smooth and efficient operation during a flight. This role includes coordinating the service provided by other flight attendants, ensuring compliance with safety regulations, and maintaining communication between the crew and the flight deck. The lead flight attendant also trains new hires, manages in-flight service processes, and serves as the point of contact for any operational issues that arise during the flight.

While managing passenger complaints can be a part of their role, it is not the central duty, as all flight attendants are trained to address passenger issues. Operating flight controls falls under the expertise of trained pilots, not flight attendants. Handling financial transactions is typically the responsibility of the airline's accounting or administrative team rather than the lead flight attendant, although they may oversee in-flight sales procedures.
