Marquette/Sawyer International Airport — Gwinn, United States

Marquette/Sawyer International Airport serves Marquette and the greater Upper Peninsula of Michigan, United States, occupying the site of a former Cold War-era Strategic Air Command base. MQT retains an unusually long runway for a regional airport, a legacy of its military past supporting large bombers, which today allows it to accommodate a wide range of aircraft. The airport provides essential air links for the sparsely populated Upper Peninsula, connecting residents and visitors to hubs like Chicago and Detroit via regional carriers. MQT also supports general aviation, cargo, and occasional charter operations tied to the region's mining, forestry, and tourism industries. Its designation as 'International' reflects historical customs capability rather than frequent international scheduled service.
