Kenai Municipal Airport covers an area of 1,200 acres (486 ha) at an elevation of 99 feet (30 m) above mean sea level. It has two runways: 2L/20R with a 7,855 by 150 feet (2,394 x 46 m) asphalt pavement and 2R/20L with a 1980 by 75 feet (604 x 23 m) gravel surface. It also has a seaplane landing area designated 2W/20W which measures 4,600 by 252 feet (1,402 x 77 m). In addition, the airport has two asphalt helipads that are 100 by 100 feet (30 x 30 m).
During the late 1970s and early 1980s, the airport had scheduled passenger jet service to Seattle (SEA). In 1979, Wien Air Alaska was operating nonstop flights to Seattle three days a week with Boeing 737-200 jetliners. By 1981, Wien Air Alaska was flying daily direct Boeing 737-200 service to Seattle via an intermediate stop in Anchorage (ANC). Wien then discontinued jet service into the airport and by 1984 was only flying nonstop service to Anchorage with all flights operated with commuter turboprop aircraft.
