Dickinson Theodore Roosevelt Regional Airport — Dickinson, United States

Dickinson Theodore Roosevelt Regional Airport, identified by the code DIK, serves Dickinson, North Dakota, a city tied historically to ranching and more recently to Bakken oil field activity. The airport underwent significant expansion with a new terminal and runway built to accommodate growth driven by the region's energy boom. DIK provides scheduled commercial service connecting Dickinson to larger hub airports, alongside general aviation and charter operations supporting oilfield logistics and business travel. Named for Theodore Roosevelt, who ranched in this part of the Dakota Badlands, the airport also supports tourism to nearby Theodore Roosevelt National Park. Its relatively small passenger volume reflects the sparsely populated surrounding area typical of western North Dakota.
