Who is responsible for crew communication regarding the flight?

The Captain is responsible for crew communication regarding the flight because, as the pilot in command, they oversee all aspects of the flight's operation, including communication among the flight crew. This encompasses relaying important information about the flight's status, safety procedures, and any changes that may occur during the journey, ensuring that all crew members are on the same page. The Captain's leadership role is vital for maintaining safety and efficiency and for directing the actions and responses of the other crew members, including flight attendants. This centralized communication helps to streamline operations and respond effectively to any issues that may arise.
