Appleton International Airport — Appleton, United States

Appleton International Airport serves Appleton, Wisconsin, and the surrounding Fox Cities area in the northeastern part of the state. Elevation reaches 918 feet, and the field's two runways support scheduled airline service alongside general aviation and cargo flights. Appleton functions as a regional alternative to Milwaukee and Green Bay, giving residents of the Fox Valley a closer option for commercial air travel. Several major U.S. carriers operate connecting flights through hub cities such as Chicago, Minneapolis, and Detroit, tying this mid-sized Wisconsin airport into the broader national network. Having a second runway allows for reliable operations despite the region's variable weather, including winter snow and ice common to Wisconsin.
