Capitan Nicolas Rojas Airport — Potosí, Bolivia

Capitan Nicolas Rojas Airport (POI) serves Potosí, Bolivia, one of the highest cities in the world and a UNESCO World Heritage site famous for its colonial silver-mining history at Cerro Rico. Sitting at extreme altitude, POI's operations are affected by thin air, which limits the payload and aircraft types able to use the airport safely. The airport connects Potosí to La Paz and other Bolivian cities, providing an alternative to the long overland journeys required to navigate Bolivia's mountainous terrain. POI plays an important role in supporting tourism to Potosí's historic mines and colonial architecture, as well as regional trade and administrative travel for this high-altitude mining region.
