About the Santiago → Buenos Aires route
Santiago to Buenos Aires is the kind of route that quietly defines South American aviation. At 1,148 km and just over 80 minutes in the air, it sits in that efficient sweet spot where flying beats any alternative without requiring you to suffer through a full travel day. LATAM (LA) owns a major chunk of this market, though Aerolíneas Argentinas (AR) runs strong competition on home turf. It's a mixed crowd — suits heading to meetings in Puerto Madero, families visiting cousins, and a steady stream of travelers who've decided Buenos Aires deserves more than a weekend.
Why travel from Santiago to Buenos Aires?
The honest reason most people make this trip is that Buenos Aires rewards you for showing up. Chileans cross the Andes specifically for the steak (the cut quality and price differential is genuinely noticeable), the live music culture in San Telmo, and a city that runs on a different social clock entirely — dinner at 10pm isn't a quirk, it's policy. There's also a strong business pull: Argentina's commercial relationship with Chile means constant corporate traffic. For culture-minded travelers, the Recoleta neighborhood alone justifies the fare, and porteño Spanish has enough personality that even fluent Spanish speakers spend the first day recalibrating their ear.

Practical tips for SCL → AEP
Buenos Aires AEP (Jorge Newbery) is genuinely one of the better short-hop airports in the region — compact, manageable, close to the city center. A taxi to Palermo or Recoleta runs maybe 20-30 minutes depending on traffic. Spring (October-November) and autumn (March-April) hit the climate sweet spot. Currency is the real gotcha: Argentina's exchange situation has historically been complicated, so check the current rate and your options before landing. If you're flying H2 (JetSMART) or another low-cost carrier on this route, read the baggage rules before you pack — carry-on allowances can be surprisingly tight.
