Alas Leuser Airport — Kutacane, Indonesia

LSR is Alas Leuser Airport, serving the town of Kutacane in the Southeast Aceh Regency of Sumatra, Indonesia. The airport takes its name from the Leuser Ecosystem, a vast and biodiverse rainforest region that includes Gunung Leuser National Park, home to Sumatran orangutans, tigers, rhinos, and elephants. LSR provides a domestic air link for this remote inland area, reducing reliance on long overland travel through Sumatra's mountainous terrain. As a small regional airport, LSR handles limited flight frequency, primarily connecting Kutacane to larger Sumatran cities, and it plays a modest but useful role in supporting conservation-related travel and local commerce in this ecologically significant part of Aceh province.
