Cincinnati Northern Kentucky International Airport

Cincinnati/Northern Kentucky International is the eighth-busiest cargo airport in North America and the seventh-busiest worldwide, handling 1.29M tonnes (2023) — a freight profile that vastly outstrips its 9.1M annual passengers. The cargo specialization dates to 2017, when Amazon selected CVG as the global headquarters and primary hub of Amazon Air, constructing a $1.5B, 3 million sq ft (278,700 sq m) sort facility adjacent to the airfield that now stages over 200 daily freighter movements. DHL operates its Americas superhub here — the company's largest hub outside Leipzig — with 100+ daily widebody departures connecting North America to Europe, Latin America, and Asia via East Midlands and Hong Kong. Atlas Air, ATSG, ABX Air, and Kalitta all maintain significant CVG operations. On the passenger side Delta Air Lines anchors a mid-sized hub (reduced from its pre-2008 peak when CVG was one of Delta's three principal connecting complexes), with supplementary service from Allegiant, Frontier, Southwest, and all major legacy U.S. carriers. British Airways provides the sole transatlantic passenger service to London-Heathrow. Across 46 airlines the airport serves 146 destinations on 290 scheduled routes. Four runways handle movements — rare for a mid-sized passenger airport but essential for cargo throughput: 09/27 at 12,001 ft (3,658 m), 18C/36C at 11,000 ft (3,353 m), 18L/36R at 10,000 ft (3,048 m), and 18R/36L at 8,000 ft (2,438 m). The parallel 18/36 triad allows simultaneous widebody operations around the clock. Terminal 3 is the sole passenger facility after Terminals 1 and 2 were demolished post-Delta's hub downscaling. The airport sits at 896 ft (273 m) elevation — one of the higher major U.S. airport elevations — on a 7,700-acre (3,116 ha) site straddling Boone and Kenton counties in Kentucky, despite serving Ohio's third-largest city.
