What is another name for the area of the aircraft designated for storing luggage?

The area of the aircraft designated for storing luggage is commonly referred to as the "baggage compartment." This term specifically identifies the section of the aircraft where checked baggage is stored, typically located in the lower fuselage, separate from passenger areas. It's important to note that while "overhead bin" also relates to luggage storage, it refers to a more specific area designed for carry-on items located above passenger seating. The other options, such as "storage unit" and "luggage space," are less formal and do not specifically designate areas on the aircraft used for luggage. The correct terminology emphasizes the function and location of the baggage area, making "baggage compartment" the accurate choice for this question.
