What is referred to as the "Cabin" of an aircraft?

The term "Cabin" of an aircraft specifically refers to the interior space that contains passenger seats and is where passengers spend the majority of their time during a flight. It is designed to provide comfort and safety for passengers and typically includes features such as seating, overhead bins for carry-on luggage, and restrooms.

This area is distinct from other parts of the aircraft; for instance, the cockpit is the area where pilots control the aircraft, and the crew rest area is designated for the flight crew to take breaks. Additionally, while there may be areas for storing luggage, such as overhead bins or the cargo hold, these are not what is referred to as the cabin. Understanding the specific functions and designations of various parts of the aircraft helps flight attendants effectively communicate and ensure passenger safety and comfort.
