In the chain of command, who holds the highest rank?

The Captain holds the highest rank in the chain of command during a flight. As the pilot in command, the Captain is responsible for the safety and operation of the aircraft, the crew, and the passengers. This role encompasses a wide range of duties, including making critical decisions regarding the flight path, handling emergencies, and ensuring compliance with aviation regulations. The authority of the Captain is recognized as paramount, which empowers them to manage the crew effectively and take command of various situations that may arise during the flight.

In the context of inflight services, the Captain's decisions and leadership are crucial for maintaining coordination among the entire crew, including the First Officer, International Purser, and Relief Officer, each of whom has specific responsibilities but ultimately report to the Captain. Knowing this hierarchy helps ensure a smooth and efficient operation, especially in challenging scenarios.
