Datadawai Airport (DTD)

Datadawai Airport (WALJ) serves Long Lunuk in Long Pahangai, Mahakam Ulu Regency, East Kalimantan, operating as the sole airport providing air service to this extremely remote region of Indonesian Borneo near the Kapuas River, the longest river in Indonesia. The facility operates without a radio control tower and handles only pioneer flights, with a runway that was lengthened and upgraded by the Indonesian government in 2015 to improve connectivity to this isolated area accessible primarily by river transport. The airport features basic infrastructure designed for small aircraft operations, with Susi Air providing the primary service offering one daily 12-seat flight to Samarinda, serving as an essential lifeline for the local communities of Mahakam Ulu Regency. The minimal terminal facilities accommodate passengers and basic cargo operations supporting the region's indigenous communities, government services, and essential supply logistics to an area where river and air transport remain the primary means of accessing the outside world. Positioned in stark contrast to East Kalimantan's extensive coal mining operations that cover 70% of the province, Datadawai Airport serves communities largely removed from the industrial activities dominating neighboring Kutai Kartanegara regency. The facility provides crucial connectivity for medical emergencies, government administration, and cultural preservation efforts in one of Indonesia's most remote regions, where traditional river communities maintain their connection to modern Indonesia through this essential aviation link in the heart of Borneo's pristine interior.
