Ralph Wien Memorial Airport (OTZ/PAOT) is a public airport located in Kotzebue, Alaska, a remote city situated above the Arctic Circle on the Baldwin Peninsula. It serves as a critical regional hub connecting Kotzebue with Anchorage and dozens of smaller bush communities across northwestern Alaska. The airport is owned and operated by the city of Kotzebue and is named in honor of Ralph Wien, a pioneering Alaska aviation figure who died in a 1930 crash. Given the region's lack of road connections to the outside world, air travel is essential for both residents and freight. The facility handles scheduled passenger service, cargo operations, and serves as a base for numerous bush flying operations that supply remote villages. It plays a vital logistical role for the region, particularly during winter months when river and sea travel is limited.
