What is considered part of the terminal building facilities?

Passenger terminals and associated parking are integral components of the terminal building facilities at an airport. These facilities are designed to accommodate the needs of travelers, including ticketing, baggage claim, concessions, and waiting areas for passengers. The associated parking areas provide a place for passengers to park their vehicles when arriving at the airport, ensuring convenience and accessibility.

In contrast, airfield runways are focused on the movement and operation of aircraft and do not pertain to terminal facilities directly. Control towers and flight operations are crucial for coordinating flights and ensuring safety but are separate from the terminal experience. Maintenance hangars, while important for aircraft upkeep, do not serve passenger services or terminal functions. This delineation highlights the specific role of terminal facilities in the overall airport operation.
