What are compartments that distinguish levels of service called?

• A. Charter
• B. Coach
• C. Configuration
• D. Classes of Service

Answer: (D)

In airline terminology, the way a flight divides itself into different levels of service is described by the term Classes of Service. Each class corresponds to a distinct level of seating, amenities, and pricing (for example, economy, premium economy, business, and first). This naming directly captures the idea of separate compartments that offer different experiences and rules.

Charter refers to private or group-specific flight arrangements, not the system of service levels. Configuration describes the physical seating layout of the cabin, which can vary but isn’t the label for the service tiers. Coach is a casual way to refer to the economy cabin and doesn’t encompass the full spectrum of service levels across the flight.
