Cleveland Hopkins International Airport — Cleveland, United States

Ohio's northern metropolis has been served by CLE since the mid-1920s, making it one of the older continuously operating commercial airports in the United States, and city boosters once promoted it during the 1930s as the busiest municipal airport in the country. The facility bears the name of William R. Hopkins, a former Cleveland city manager who championed municipal aviation infrastructure decades before jet travel became routine. A defining feature arrived in 1968, when Cleveland connected the airport directly to downtown via rail transit, becoming the first American airport with a direct rapid-transit link to a city center, a model other cities would later study and imitate. Once a major hub for Continental Airlines and subsequently United Airlines following their merger, the airport's hub status was scaled back to a focus-city operation in 2014, reshaping its route map toward more point-to-point domestic service. Multiple parallel runways handle both passenger and considerable cargo traffic, and the airport continues to anchor air travel for Northeast Ohio, including Akron and the broader Lake Erie shoreline region.
