Kasiguncu Airport — Poso-Celebes Island, Indonesia

PSJ, Kasiguncu Airport, serves Poso on Sulawesi Island in Indonesia, a region known for its lake and agricultural landscapes as well as periods of past civil unrest that affected local infrastructure development. PSJ handles domestic flights connecting Poso to regional hubs like Makassar and Palu, providing essential air access given the area's mountainous terrain and limited road quality. The airport supports modest passenger volumes primarily tied to local government, business, and family travel needs. PSJ's short runway and basic terminal facilities reflect its role as a small regional gateway rather than a major transport hub, typical of many airports serving Sulawesi's interior communities.
