The short hop across the Andes from Buenos Aires Aeroparque to Santiago is one of South America's most iconic air corridors, connecting two vibrant capitals separated by the world's longest continental mountain range. At just under two hours, it is the kind of flight that feels almost effortless yet delivers one of aviation's most spectacular window-seat experiences.
Departing from Aeroparque Jorge Newbery, which sits right along the Río de la Plata waterfront in the heart of Buenos Aires, travelers enjoy the convenience of a city-center airport. The location alone saves considerable time compared to the larger Ezeiza international hub. As the aircraft climbs westward, passengers on the left side of the cabin are often treated to panoramic views of the Andes, including glimpses of Aconcagua, the tallest peak in the Western Hemisphere. On clear days, the snowcapped ridgeline stretching to the horizon is genuinely breathtaking.
Several airlines operate flights from AEP to SCL throughout the day, including Aerolíneas Argentinas, LATAM, and JetSMART. Frequencies are generous, with multiple daily departures that make same-day connections and flexible scheduling relatively easy. LATAM and Aerolíneas Argentinas tend to offer full-service options with complimentary snacks and beverages, while JetSMART provides a no-frills alternative at lower fares for those willing to forgo extras.
Timing your trip wisely can enhance the experience significantly. Spring, from September through November, brings mild temperatures and blooming jacarandas in Buenos Aires alongside pleasant weather in Santiago. Autumn, March through May, is equally appealing, with fewer crowds and warm days on both sides of the cordillera. Winter travelers should note that Andean weather can occasionally cause delays or diversions, though modern routing and improved forecasting have made disruptions less common than in decades past. Summer remains peak season, and fares reflect the demand accordingly.
Upon arriving at Santiago's Arturo Merino Benítez International Airport, the city unfolds with its own distinct energy. Where Buenos Aires charms with European architecture and late-night dining culture, Santiago offers a backdrop of mountains visible from nearly every neighborhood, a booming food scene, and easy access to both Pacific coast beaches and ski resorts in the Andes.
A few practical tips worth noting: Argentine exit taxes and Chilean entry requirements change periodically, so checking current regulations before departure is always wise. Currency exchange rates between the Argentine peso and Chilean peso fluctuate frequently, and carrying some local currency for ground transportation on arrival can smooth the transition. For those flying from Buenos Aires Aeroparque to Santiago regularly, airline loyalty programs on this route accumulate miles quickly given the frequency of service. It is a route that rewards repeat visitors with familiarity and, every single time, those incomparable mountain views.
