Yellowstone Regional Airport — Cody, United States

Named for its bustling gateway city rather than the national park it serves, COD sits just east of Cody, Wyoming, a town founded by and named after the famed showman and frontiersman Buffalo Bill Cody. Seasonal tourist traffic surges each summer as travelers use the airport to reach Yellowstone National Park's less-crowded east entrance, following the scenic Buffalo Bill Cody Scenic Byway through Wapiti Valley toward Sylvan Pass. Sitting at a fairly high elevation typical of Wyoming's Bighorn Basin fringe, the airport handles regional jet service that ebbs and flows with the tourist season far more dramatically than airports serving year-round urban populations. Cody itself trades heavily on its Wild West heritage, hosting nightly rodeo performances in summer and housing the extensive Buffalo Bill Center of the West museum complex not far from the runway.
