Port Heiden Airport — Port Heiden, United States

PTH, Port Heiden Airport, serves the small community of Port Heiden on the Alaska Peninsula in the United States, an area accessible almost exclusively by air due to its remote location facing the Bering Sea. The airport supports Essential Air Service flights connecting residents to larger Alaskan hubs, providing critical access for supplies, medical needs, and travel in a region with no road connections to the rest of the state. PTH also serves as a base for subsistence hunting and fishing activities central to the local Alutiiq community's way of life. The airport's long runway, a legacy of a former Air Force radar station in the area, exceeds what its current small-scale traffic requires.
