CVG is a small, easy-to-navigate airport built around a single terminal with two connected concourses, making it one of the least stressful connection experiences in the U.S. Since Delta downsized its hub operations here, traffic is lighter than the terminal's size once anticipated, though DHL's massive cargo hub keeps the airport busy overnight. Most passenger connections involve short walks with no need for shuttles or trains except at peak congestion points. Concourses A and B are connected via an enclosed, climate-controlled walkway with moving sidewalks that runs through the central terminal atrium — no train or shuttle is required. Security is centralized at the terminal entrance, so once through screening, passengers move airside between concourses without additional checkpoints. International arrivals (limited, mostly via Allegiant or seasonal charters) clear CBP in a dedicated federal inspection area near Concourse A before continuing landside.
