Fort McMurray International Airport — Fort McMurray, Canada

Fort McMurray International Airport (YMM) serves as the primary aviation gateway to Alberta's oil sands region, one of the largest petroleum reserves on earth. The airport handles substantial passenger traffic tied directly to the energy industry, ferrying workers to and from major oil sands operations alongside regular commercial service to Calgary, Edmonton, and other Canadian cities. YMM gained international attention during the devastating 2016 wildfire that forced a mass evacuation of Fort McMurray, with the airport serving as a critical staging point. Its modern terminal, built to accommodate boom-driven passenger growth, reflects decades of economic expansion fueled by bitumen extraction and processing in the surrounding Athabasca region.
