Routes / Buenos Aires / Buenos Aires to Santiago

Buenos Aires Santiago

Q: Can I do a same-day round trip between Buenos Aires and Santiago?

Yes, and business travelers do it regularly. Early departures from Aeroparque land in Santiago by mid-morning. Evening flights return you to Buenos Aires the same night. The time difference is one hour or less depending on the season.

2 nonstop pairs · 5 nonstop airlines · 164 nonstop flights/week

Aeroparque runs flights to Santiago every hour all day, and the airport sits two kilometers from downtown Buenos Aires.

If you are staying anywhere in Buenos Aires, fly from Aeroparque. Aerolineas Argentinas, LATAM, SKY Airline, and JetSMART all serve the route. JetSMART and SKY are low-cost carriers that will undercut the others on a 2.4-hour flight where the cabin experience is the same across all four. Book whichever is cheapest.

If you are connecting from another country or already near Ezeiza, SKY Airline, JetSMART, and LATAM fly from there too. The flight is 2.2 hours, but Ezeiza is 35 km south of the city. Unless you are already out there, you lose on the ground whatever you save in the air.

KLM shows up on the Ezeiza route, but that is a segment of their Amsterdam service passing through. Skip it unless you are connecting to or from Europe.

Sit on the left side going westbound, right side coming back. The route crosses the Andes at high altitude, and on a clear day you get a full view of Aconcagua and the glacial valleys below.

Best pair by where you're staying in Santiago

Lounge access by airport and terminal

Premium lounge access varies dramatically by terminal. This alone can determine airport choice for some travelers.

The largest lounge in Terminal A. Open to business class passengers and top-tier Aerolineas Argentinas status holders. Showers, hot food, and a bar. Comfortable for long layovers.

Access for LATAM business class passengers and qualifying partner airline status holders. Quieter than the Aerolineas space, with food, drinks, and decent seating. Located in Terminal A.

Several lounges at Ezeiza accept Priority Pass. Quality varies between terminals. Check the Priority Pass app before clearing security to confirm which lounge matches your gate.

Lounge options in Terminal B are more limited than Terminal A. If your flight departs from Terminal B, check whether your lounge membership or status grants access on that side.

Located in the departures area. Open to business class passengers and Aerolineas Argentinas elite status holders. Compact space with drinks, snacks, and Wi-Fi. Not a full-service international lounge, but a quiet place to wait.

Priority Pass cardholders can access a small lounge inside the terminal. Check the app for current hours and capacity. The space is basic.

Aeroparque is a smaller terminal and lounge options reflect that. If you do not have airline status or a lounge membership, the post-security cafe is your best option.

The largest and best-equipped lounge at Santiago airport. Open to LATAM business class and oneworld Sapphire or Emerald members. Full food service, bar, showers, and runway views. One of the better airline lounges in South America.

Several lounges in both the domestic and international areas accept Priority Pass. Quality and crowding vary by time of day. Worth checking current options before traveling.

Smaller lounges serve the domestic gates. Access through airline status or lounge memberships. Basic coffee, snacks, Wi-Fi, and quiet seating.

Your airline and cabin class determine which lounges you can access.Check route pages for terminal assignments.

Getting to the airport

Cost and time vary by mode. Train is more predictable than driving.

Taxis and remises queue outside arrivals. The ride to downtown takes 45 to 60 minutes depending on traffic. Fares are higher than from the city airport because of the distance. Confirm the rate or use the meter before departing.

Scheduled bus services run between the airport and central Buenos Aires. The ride takes around 60 minutes. Tickets are available at counters in the arrivals hall. Buses drop you in the city center near subway and taxi connections.

Uber operates from the airport. Pickup works from the arrivals area. The ride takes about the same time as a taxi. Fares can be slightly cheaper depending on demand.

Rental agencies have counters in the terminal. The drive into the city takes 45 to 60 minutes on the highway. Useful if your trip extends beyond Buenos Aires or if you want to avoid the return taxi fare.

Taxis line up outside arrivals. The ride to downtown takes 10 to 15 minutes. Fares are low by international standards. Official taxis have meters and no negotiation is needed.

Uber and other apps work from the terminal. Some drivers prefer you sit in the front seat to avoid friction with the taxi line. Reliable and slightly cheaper than a metered taxi.

City buses stop near the terminal entrance. Fares cost very little. Useful if you know the bus network, but with taxis this affordable most travelers skip it.

Rental counters are inside the terminal. City traffic is dense and street parking in popular neighborhoods is limited. A car makes more sense for trips extending beyond the metro area.

Weigh transit time against schedule flexibility.A faster airport with fewer flights may not save you time overall.

Premium cabin options

Business and first class products on this route, ranked by value and quality.

The only lie-flat business class between the two cities. LATAM flies its 787 on select Ezeiza departures with a proper flat bed and meal service. Worth booking if you need to arrive rested. Factor in the drive to Ezeiza.

Aerolineas Argentinas and LATAM sell business class on their 737s and A320s. The seat is a recliner with extra legroom, not a flat bed. On a two-hour flight, the value is in the space, priority boarding, and included meal.

Neither carrier offers a premium cabin. Economy seats are standard for the aircraft type. On a two-hour flight, the savings over business class buy you a nice dinner in Santiago instead.

Check route pages for cabin details per airline.Business class products vary significantly between carriers.

Connecting through Buenos Aires from a domestic flight

Direct flights leave Aeroparque for Santiago throughout the day. Connecting through a third city adds hours and costs more. The only scenario where a connection makes sense is if you are originating from a smaller city in Argentina or Chile without direct Santiago service.

Buenos Aires & Santiago Airport Profiles

Each airport has a personality. Terminal quality, transit access, lounge scene, and crowd levels vary dramatically — sometimes more than the flight itself.

Buenos Aires Metro

Aeroparque Jorge Newbery sits on the Rio de la Plata waterfront, two miles from downtown Buenos Aires. A single terminal handles domestic and regional flights in a compact layout. Walking distances are short from check-in to any gate.

The building is modest. Dining and shopping cover the basics without much variety. Security lines build during the morning rush, though the terminal is small enough that even a busy checkpoint clears quickly. The waterfront location puts the city center within a 15-minute drive.

Ezeiza Ministro Pistarini International sits 22 miles south of downtown Buenos Aires, past the city suburbs. Two terminal buildings handle different airlines and flight types. Terminal A serves the majority of traffic. The walk between terminals takes a few minutes outside.

The terminals received upgrades in recent years with improved retail, food options, and wayfinding. Post-security dining is reasonable without being extensive. The airport is large enough that knowing your terminal before arrival saves time. Early morning departures mean leaving the city well before dawn.

Santiago Metro

Comodoro Arturo Merino Benitez sits 18 km west of Santiago in Pudahuel. The terminal handles domestic and international flights under one roof, keeping connections simple.

After security, the gate area runs along a single concourse with food, duty-free, and seating. Walking times from security to the farthest gates are around 10 to 15 minutes. Signage is clear in Spanish and English.

Arrivals open into a hall with ATMs, SIM card vendors, and ground transport counters. The exit flow is direct and rarely congested outside of early morning arrival clusters.

Which Airlines Fly Which Pairs

Not all planes are the same size. The aircraft type below each checkmark tells you whether you are getting a widebody (777, 787, A350) with wider seats and a quieter ride, or a narrowbody (737, A321) with a single aisle. On flights over five hours, the difference is significant.

FAQ

Frequently Asked Questions

Common questions about Buenos Aires to Santiago flights.

Only if premium cabin matters. LATAM's 787 from Ezeiza has lie-flat business class that no narrow-body from Aeroparque can match. But Ezeiza is 35 km from the city center, and Aeroparque has far more departures. For economy passengers, Aeroparque wins on every measure.

Base fares on JetSMART and SKY often run well below Aerolineas and LATAM. The gap narrows once you add a checked bag and seat selection. If you are traveling light with fixed dates, the savings are significant. If your schedule might change, the full-service fare includes rebooking flexibility that the low-cost carriers charge extra for.

Centropuerto and TurBus run express buses from the terminal to central Santiago in around 30 minutes. Taxis take similar time. The airport is 18 km west of the city center. The express bus offers the best balance of speed and cost.

On the Aeroparque flights, business class is a recliner seat with extra legroom and a meal. It is not a flat bed. The main benefit on this flight length is space and priority boarding, not sleep. If you want a lie-flat seat, LATAM's 787 from Ezeiza is the only option.

Yes, and business travelers do it regularly. Early departures from Aeroparque land in Santiago by mid-morning. Evening flights return you to Buenos Aires the same night. The time difference is one hour or less depending on the season.

KLM operates the Ezeiza to Santiago leg as part of its Amsterdam service. It is not an independent Buenos Aires to Santiago route. For a dedicated flight from Ezeiza, book LATAM, JetSMART, or SKY Airline.
