McGhee Tyson Airport — Knoxville/Maryville, United States

Knoxville and the wider East Tennessee region rely on McGhee Tyson Airport, known to travelers by its TYS code, for scheduled commercial air service from a location in Alcoa, a few miles south of the city itself. The airport takes its name from Charles McGhee Tyson, a Knoxville native and naval aviator who died during World War I, and it shares its grounds with the Tennessee Air National Guard's 134th Air Refueling Wing. Beyond its passenger role, TYS serves as a popular entry point for visitors bound for the Great Smoky Mountains National Park, one of the most visited national parks in the country, as well as for the University of Tennessee community in nearby Knoxville. Several major carriers offer nonstop routes to hub airports across the eastern and central United States, with periodic terminal renovations keeping pace with regional travel growth.
