Dr. Ferdinand Lumban Tobing Airport — Sibolga (Pinangsori), Indonesia

FLZ identifies Dr. Ferdinand Lumban Tobing Airport, which serves Sibolga on the western coast of North Sumatra, Indonesia. Named after a respected Batak physician and independence-era figure, the airport provides a crucial air link for a region hemmed in by mountainous terrain that makes overland travel to Medan slow and difficult. Domestic carriers operate short-haul flights connecting Sibolga to larger Sumatran hubs, supporting trade, fishing industry logistics, and access to the nearby Nias Islands. The airport's modest single runway and terminal reflect the scale of local demand rather than any lack of importance, since for many Sibolga residents FLZ-linked flights are the fastest way in or out of the region during monsoon-affected road conditions.
