Peninsula Airways, commonly known as PenAir, is a regional airline headquartered in Anchorage, Alaska. Founded in 1955, it has long served as a critical transportation lifeline for remote communities across Alaska, particularly on the Alaska Peninsula and the Aleutian Islands. The airline operates scheduled passenger and cargo services to communities that are otherwise inaccessible by road, making it an essential part of Alaska's regional transportation infrastructure. PenAir has historically operated under codeshare arrangements with larger carriers to connect its passengers to the broader national air network. Over its decades of operation, PenAir has navigated the significant challenges of Alaskan bush flying, including extreme weather conditions and the logistical demands of serving isolated communities. The airline has undergone various ownership changes and restructuring efforts while maintaining its commitment to rural Alaskan air service.
