Chan Gurney Municipal Airport — Yankton, United States

Chan Gurney Municipal Airport, coded YKN, serves Yankton, South Dakota, a city along the Missouri River in the southeastern part of the state. Named after former U.S. Senator Chan Gurney, the airport primarily supports general aviation, charter flights, and occasional scheduled service connecting Yankton to regional air travel networks.
