Antonio Nariño Airport (PSO)

Antonio Nariño Airport (PSO) is the primary aviation hub serving the city of Pasto and the Nariño Department of Colombia, located in the municipality of Chachagüí approximately 22 miles (35 km) north of the city center. The airport operates from a modern, integrated passenger terminal that recently underwent a major renovation to provide high efficiency and improved accessibility. It acts as a critical infrastructure link, connecting the southern Andean region to major national hubs like Bogotá and Cali via carriers such as Avianca, LATAM, and Clic.

The terminal infrastructure provides a variety of contemporary amenities across its unified layout, featuring several landside cafés and snack bars that serve traditional Colombian coffee and regional pastries. Travelers have access to comfortable airside waiting lounges, a dedicated information desk, and retail kiosks offering local handicrafts and travel essentials. The facility is fully accessible and maintains a professional environment, though passengers should note that it primarily handles domestic traffic and provides a streamlined experience for those transitioning to the regional administrative districts.

A world-renowned feature of PSO is its unique 'table-top' runway, frequently referred to as 'The Aircraft Carrier' because it is built on a plateau that ends abruptly at the edge of a 50-meter drop. This high-altitude environment in the Andes requires pilots to manage complex wind patterns and frequent low-visibility conditions, supported by a modern Instrument Landing System (ILS). Ground transportation to central Pasto is well-supported by official taxi ranks and shared 'colectivo' services situated directly outside the terminal exit, with the journey typically taking between 40 and 60 minutes via the scenic mountain highway.
