The BNA® Master Plan considers the passenger experience when planning passenger terminal facilities; everything from walking distances, to the number of ticketing counters, to the size of baggage claim are taken into account. Industry standards, such as International Air Transport Association (IATA) levels of service, are used as a reference point to inform the size of the terminal areas. Ultimately, any changes in response to the BNA® Master Plan will support the airport’s mission: to provide outstanding customer service, facilities and air service in a safe and secure environment.
