Quick verdict
A two-hour regional hop that LATAM runs like a bus service - frequent, functional, unremarkable. The seat is standard short-haul economy, the service is drinks only, and the AEP terminal experience is limited. None of that matters if you get a window seat on a clear day: the Andes crossing is one of the most spectacular views you will ever see from a plane. Book the window, accept that the food situation is basically nonexistent, and enjoy the mountains. For what this flight is - a short connection between two South American capitals - LATAM does a competent job.
Booking
LATAM dominates the Buenos Aires to Santiago route, with multiple daily frequencies. Fares are competitive and there is little reason to look beyond LATAM unless you are chasing specific alliance miles. This route departs from Aeroparque (AEP), not Ezeiza - a significant advantage since AEP is only 15 minutes from central Buenos Aires.
Book direct through LATAM for the simplest experience. The Buenos Aires to Santiago route is one of the most-flown in South America, so availability is rarely an issue.
The airport experience
AEP’s international departure area is small and functional. Do not expect lounges, extensive duty free, or a wide range of food options. There is a Tienda de Sabores for snacks and the duty free is overpriced for what it offers. The gate areas are compact. Arrive two hours before departure and you will have time to spare - possibly too much, given the limited facilities.
The boarding process was orderly. AEP handles a mix of domestic and regional flights and the terminal feels like a regional airport, which is essentially what it is.
The seat
Standard short-haul economy. Blue leather seats that have seen better days but are comfortable enough for a two-hour flight. Legroom is adequate. The seat width is fine. Nothing to complain about and nothing to celebrate - it is a bus seat for the sky.
Power outlets were not available at the seat. For a two-hour flight, that is barely worth mentioning.
Service
Drinks only. A cart passes through with water, soft drinks, and juice. No food service, no snack box, nothing to purchase. For a two-hour-twenty-minute flight this is not unreasonable, but eat before you board or bring something.
The cabin crew were professional and efficient. They got the drink cart through quickly and cleaned up before descent. No complaints.
The route
This is the real reason to pay attention. The Buenos Aires to Santiago route crosses the Andes, and on a clear day the views from a window seat are extraordinary. Snow-covered peaks, glaciers, and mountain valleys stretching to the horizon. Book a window seat on the right side (heading westbound) for the best perspective.
Turbulence crossing the Andes is common and sometimes significant. The seatbelt sign comes on for a reason. This is normal for the route and the pilots handle it matter-of-factly. If turbulence makes you nervous, know what to expect.
The descent into Santiago is dramatic, with the city appearing suddenly against the mountain backdrop.

LATAM’s Buenos Aires to Santiago is a functional regional service elevated by extraordinary scenery. The airline does nothing wrong and nothing exceptional. The Andes do the rest. Book the window seat.
