How a flood-prone airfield transformed into a global powerhouse for Amazon and DHL
In short: Originally conceived as a World War II training site to escape the flood-prone Ohio River Valley, Cincinnati/Northern Kentucky International Airport has undergone a radical metamorphosis. Once a dominant passenger hub for Delta Air Lines, it has reinvented itself as a critical global nexus for the world's largest air cargo operations.
The airport's origins trace back to February 1942, when the Roosevelt administration approved funds for a new airfield to support the United States Army Air Corps. Local officials in Boone, Kenton, and Campbell counties seized the opportunity to bypass the flood-prone Lunken Airport, securing the site despite Cincinnati's initial preference for its existing facility. By August 1944, the field was operational, though it was declared surplus shortly after the war ended in 1945. Commercial service began in 1947, and the facility steadily expanded through the mid-20th century, notably embracing the jet age in 1960.
The airport's trajectory shifted dramatically in the 1980s and 1990s as it became a major hub for Delta Air Lines and its subsidiary, Comair. At its peak in 2005, CVG handled over 600 daily flights, serving as the world's fourth-largest hub for a single airline. However, the subsequent decade brought severe contraction. Following Delta's bankruptcy and the 2008 merger with Northwest Airlines, the airport saw massive flight reductions, the closure of multiple terminals, and the eventual cessation of Comair's operations in 2012. By 2017, the former hub had been downgraded to a focus city and eventually lost that status entirely.
In the wake of this passenger decline, the airport pivoted toward logistics. DHL established a hub in 1984, and in 2017, Amazon Air selected CVG as its primary worldwide shipping hub, investing $1.49 billion in infrastructure. Today, the airport is the fifth-busiest in the United States by cargo traffic and the twelfth-largest globally. Beyond its industrial utility, the airport preserves cultural history, housing five of the original 1932 Art Deco murals from the Cincinnati Union Terminal, which were relocated to the airport following the demolition of the train concourse in 1972. These murals, along with artwork by Charley Harper, offer a unique aesthetic contrast to the high-speed sorting facilities that now process an estimated 50 million packages monthly.
