The short hop across the Andes from Santiago de Chile to Buenos Aires is one of South America's most iconic air routes, connecting two vibrant capitals that couldn't be more different in character. Flights from SCL to EZE cover roughly 1,140 kilometers and take just under two hours, making it an easy journey whether you're traveling for business, pleasure, or a long weekend escape.
One of the undeniable highlights of this route is the scenery. On a clear day, passengers seated on the left side of the aircraft are treated to sweeping views of the Andes mountain range, with snow-capped peaks stretching as far as the eye can see. It's one of the few flights where even seasoned travelers press their faces to the window. The sight of Aconcagua, the highest peak in the Western Hemisphere, is genuinely breathtaking from cruising altitude.
Several major airlines serve the Santiago to Buenos Aires corridor, including LATAM Airlines, Aerolíneas Argentinas, JetSMART, and SKY Airline. The mix of full-service and low-cost carriers means there are options across every budget. LATAM and Aerolíneas Argentinas typically offer more generous baggage allowances and onboard service, while JetSMART and SKY keep fares competitive with no-frills pricing. Flights depart throughout the day, with early morning and evening departures being especially popular among business travelers.
There's no single best time to fly this route, as both cities have year-round appeal. Buenos Aires is particularly enchanting in spring, from September through November, when jacaranda trees paint the city purple and temperatures are mild. Santiago, meanwhile, shines in the Southern Hemisphere autumn months of March through May. If you're planning to explore wine country on either side, harvest season in February and March is ideal.
A few practical tips are worth noting. Buenos Aires has two airports, and international flights land at Ezeiza, which sits about 35 kilometers outside the city center. Budget at least an hour for the transfer into town, and consider arranging a remise or using the Tienda León shuttle service. Currency exchange rates between Chilean pesos and Argentine pesos can be confusing, so it helps to research the current blue dollar rate before arrival.
The connection between Santiago and Buenos Aires represents more than just a flight. It links two of South America's most culturally rich cities, each offering world-class food, nightlife, and history. Whether you're drawn to the tango halls of San Telmo or the street art of Bellavista, this route opens the door to unforgettable experiences on both sides of the Andes.
