About the Buenos Aires → Santiago route
Buenos Aires to Santiago is one of South America's most well-traveled short-haul routes — just 1,148 km and roughly 81 minutes in the air, which means you're barely at cruising altitude before the Andes start filling the window. LATAM (LA) dominates here, as you'd expect given it's essentially a home route for them, but Aerolíneas Argentinas (AR) competes hard, and a couple of lower-cost options have entered the mix. The passenger mix skews business and government during the week, then flips to families and weekend travelers on Fridays and Sundays. It's not glamorous flying, but it's efficient.
Why travel from Buenos Aires to Santiago?
The obvious pull is the Andes themselves — Portillo and Valle Nevado are legitimate world-class ski destinations, and Argentine skiers who've done Bariloche often cross the mountains to compare notes. Beyond that, Santiago's Lastarria neighborhood offers a genuinely different dining and cultural register than Buenos Aires — less European-inflected, more Pacific Coast. Wine tourism in the Maipo and Casablanca valleys draws serious drinkers who want to see how Chilean winemaking differs from Mendoza. Business travel between the two capitals is constant — Santiago is the regional headquarters for a lot of multinationals that also operate in Argentina. And family connections across the border run deep, especially post-pandemic, when a lot of Argentines relocated.

Practical tips for AEP → SCL
If you're flying low-cost (H2 or JA), read the baggage policy twice — carry-on allowances can be tighter than you'd expect on a route this short. Santiago's airport (SCL) is modern and immigration moves reasonably well, though peak Sunday evenings can back up. The Centropuerto bus to Pajaritos metro station costs a fraction of a taxi and drops you into the city's subway network cleanly. Chileans use pesos (CLP), not Argentine pesos — don't assume. Spanish is shared, obviously. Fare-wise, shoulder season (March-April, September-October) tends to offer the best prices without the winter ski rush or summer holiday premium.
