Basco Airport (IATA: BSO, ICAO: RPUO) is the primary airport serving Basco, the capital of Batanes province in the northernmost part of the Philippines. Situated on Batan Island, the airport provides the main link between the isolated Batanes archipelago and the Philippine mainland, particularly Manila and Tuguegarao. The airport is operated by the Civil Aviation Authority of the Philippines (CAAP) and handles a modest volume of passengers given the small population of the province. Its remote location and the rugged terrain of the island make air travel the most practical means of reaching Batanes. Batanes is known for its dramatic landscapes, traditional Ivatan stone houses, and strong winds influenced by Pacific typhoons. The airport plays a vital role in connecting residents and tourists to the rest of the country, though flights can be disrupted by adverse weather conditions common in the region.
