Minneapolis–Saint Paul International Airport / Wold–Chamberlain Field — Minneapolis, United States

Built on the site of the old Wold-Chamberlain Field, Minneapolis–Saint Paul International Airport, coded MSP, grew into one of the busiest hubs in the American Midwest largely on the strength of Northwest Airlines, whose merger into Delta Air Lines in 2008 left Delta with a dominant hub role it still holds today. Two main terminals, Lindbergh and Humphrey, split traffic between major legacy-carrier operations and a mix of international and low-cost service, and the airport connects the Twin Cities to destinations across North America, Europe, and Asia. Minnesota's harsh winters test the airport's operations every year, and MSP has built a reputation for effective snow removal and deicing procedures that keep delays lower than the climate might suggest. Light rail service links the terminals directly to downtown Minneapolis and Saint Paul, an integration many larger American airports still lack. Its efficient layout and connections regularly earn it favorable marks in passenger satisfaction surveys.
