Tununak Airport (TNK)

Tununak Airport (IATA: TNK, FAA LID: 4KA) is a state-owned, public-use airport that serves as a critical transportation link for the remote village of Tununak, Alaska. Located on Nelson Island in the Bethel Census Area, the airport is the primary means for transporting residents, mail, cargo, and essential supplies. For the approximately 400 residents of the Cup'ik Eskimo village, the airport provides year-round access to the regional hub of Bethel and, by extension, the rest of the world, a function that is especially vital when sea ice or weather conditions restrict marine travel.

Established in December 1974, the airport has been an integral part of the community’s infrastructure for decades. Its significance lies not in major historical events, but in its consistent, daily role of connecting an isolated population with medical services, economic opportunities, and vital goods. The airport is situated less than one mile southeast of the village center, making it accessible to residents. Travel between the village and the airport is typically accomplished on foot or by all-terrain vehicles (ATVs), as there are no formal taxi or public transportation services available.

Operations at Tununak consist exclusively of domestic, short-haul flights operated by regional air taxi services. Grant Aviation is the primary airline, offering scheduled passenger service to and from Bethel (BET). These flights are essential for connecting passengers to the wider commercial air network. The airport handles several thousand passenger enplanements annually, reflecting its steady use by the local population. All flights utilize the airport's single gravel runway, designated 13/31, which measures 1,770 by 45 feet.

Facilities at Tununak Airport are basic and functional, designed to meet the essential needs of regional air travel. There is no traditional terminal building with amenities like restaurants, shops, or passenger lounges. Instead, a small shelter provides a waiting area for passengers. Travelers should not expect services such as TSA security checkpoints or extensive baggage handling systems. For those planning to fly to or from Tununak, it is wise to arrive approximately 30 to 60 minutes before a scheduled flight, but always confirm with the airline. Due to the small aircraft used, strict baggage weight and size limits are enforced. The most important consideration is the weather, which can cause significant flight delays or cancellations. Visitors should build flexibility into their travel schedules to account for potential disruptions.
