Ketchikan International Airport is a state-owned, public-use airport located one nautical mile (2 km) west of the central business district of Ketchikan, a city in Ketchikan Gateway Borough in Alaska, U.S. state that has no direct road access to the outside world or to the airport. The airport is located on Gravina Island, just west of Ketchikan on the other side of the Tongass Narrows. Passengers must take a seven-minute ferry ride across the water to get to the airport from the town. As per Federal Aviation Administration records, the airport had 108,837 passenger boardings (enplanements) in calendar year 2008, 96,996 enplanements in 2009, and 100,138 in 2010. It is included in the National Plan of Integrated Airport Systems for 2015–2019, which categorized it as a primary commercial service (nonhub) airport (more than 10,000 enplanements per year) based on 103,136 enplanements in 2012. History Around the World War II era until the early 1970s, longer range land plane air service to Ketchikan including flights to Seattle were operated via an old military airfield located approximately 20 air miles to the south on Annette Island. Aircraft operated into the Annette Island Airport (ANN) for flights in the local southeast Alaska area included the Grumman Goose and Catalina PBY with these amphibian aircraft being utilized to link the airport with the Ketchikan Harbor Seaplane Base. Longer range flights serving Annette Island were operated with Douglas DC-4 prop aircraft flown by Pan American World Airways during the 1940s followed by Douglas DC-6 and Boeing 377 Stratocruiser aircraft. Other service into the Annette Island Airport included Lockheed Constellation propliners flown by Pacific Northern Airlines during the 1950s and Boeing 707 jetliners flown by Pan Am in the early 1960s. In addition, Annette Island was served with Boeing 720 jetliners operated by Pacific Northern and successor Western Airlines later during the 1960s. Alaska Airlines also operated into Annette Island Airport prior to moving its jet service to Ketchikan International Airport with the opening of this new airfield. The current airport was opened on August 4, 1973, and was dedicated on the following day. The airport opening was the culmination of an effort by local residents, a 1965 study by the Alaska State Division of Aviation, another study in 1967 choosing the current site on Gravina Island, and land clearing in 1969. One of the first airlines to serve the new airport was Alaska Airlines which
