About the Buenos Aires → Santiago route
Buenos Aires to Santiago is one of those routes that sounds more dramatic than it is. You're crossing the Andes, sure, but the flight itself is barely 1 hour 20 minutes — shorter than some domestic hops I've taken within Argentina. LATAM (LA) runs this corridor constantly, and you'll share the cabin with a pretty even mix of business travelers, Argentines visiting family, and backpackers who figured the bus over the mountains was more adventure than they needed. It's firmly short-haul, and it shows — don't expect much beyond a drink service before you're already descending.
Why travel from Buenos Aires to Santiago?
The obvious answer is Patagonia — Chileans and visiting Argentines both use Santiago as a jumping-off point for the south, and SCL's 63 non-stop destinations mean you can connect onward fast. But Santiago itself earns the trip. Bellavista, the bohemian neighborhood that climbs toward Cerro San Cristóbal, feels noticeably different from Buenos Aires — quieter streets, Pacific-influenced seafood, pisco replacing fernet in the bars. Argentines cross the border for the wine valleys too, particularly Maipo and Casablanca, which are an easy day trip from the city. There's also a practical business pull — Santiago is the corporate capital of South America in many respects, and the EZE–SCL route reflects that Monday-morning, Friday-evening rhythm you see on serious business corridors.

Practical tips for EZE → SCL
Spring (September to November) and autumn (March to May) hit the sweet spot — mild weather in Santiago and generally softer fares than the December-January summer rush when half of Buenos Aires relocates to the Chilean coast. At SCL, immigration is straightforward for Argentine and most Western passport holders — no visa required, just your tourist card. The Centropuerto bus runs directly to the city center for a few dollars and is genuinely reliable; taxis are pricier and negotiation is expected. One thing to watch: if you're flying a low-cost carrier like H2, check baggage allowances carefully — carry-on-only fares are common and the fees for adding a bag at the gate sting.
