Northeast Wyoming Regional Airport — Gillette, United States

Northeast Wyoming Regional Airport (GCC), historically known as Gillette-Campbell County Airport, serves Gillette, a city at the center of the Powder River Basin coal mining industry. GCC handles commercial passenger service alongside significant general aviation and charter traffic tied to the energy sector, including flights supporting coal, oil, and gas operations throughout the surrounding basin. The airport's role reflects the boom-and-bust economic rhythms of the region's extractive industries, with traffic levels historically tracking energy prices and mining activity. Scheduled airline service connects Gillette to hub airports like Denver, giving residents and energy company personnel a practical alternative to the long highway drive across Wyoming's sparsely populated plains.
