The Cincinnati/Northern Kentucky International Airport has a single passenger Terminal. It consists of Concourse A and Concourse B.
Concerning the main Terminal, it is divided into three levels: Level 1 is used as a Meeting Point area; Level 2 hosts arrivals, houses Baggage Claim; Level 3 holds areas for Check-In and Departure Facilities.
The general boarding space leads the security check area and gives access to both Concourse A and B through elevators, or stairs. Hence, there is no need to use the Shuttle bus as everything, services, and facilities are available in one Terminal, but on different levels.
