Which term describes the area where passengers are seated in an aircraft?

The area where passengers are seated in an aircraft is referred to as the cabin. This term encompasses the main passenger seating area, as well as the sections for amenities provided to travelers, such as overhead compartments for personal items and designated spaces for in-flight services.

In contrast, the cockpit is the area where pilots operate the aircraft and handle navigation and communication. The cargo bay is specifically designed for storing luggage and freight, completely separate from the passenger space. The galley is the kitchen area where in-flight meals and beverages are prepared and stored. Each of these terms plays a distinct role in the overall functioning of an aircraft, but the cabin is solely focused on the passenger experience and seating arrangements.
