Cheap Flights from Barcelona to Santiago de Chile in 2026

Chile stretches 4,300 km and Santiago is its operations center: from there you drop south to Patagonia, hop to Valparaíso, or head into the wineries of the central valley. The flight from Barcelona is one of the longest you can take (over 11,000 km), yet fares start from around €620 return. First things first: search and book your Barcelona–Santiago flight with TopTravelCentre and see which connections are available on your dates.

How to find cheap flights Barcelona to Santiago

With no nonstop on the route, the connection is everything. These are the three classic routings and what to expect from each:

Via Madrid (Iberia or LATAM): the fastest, about 17–18 hours total, with excellent connections out of Barcelona.
Via São Paulo (LATAM): you enter Chile through South America; often the lowest fare, with 20–23 hours of travel.
Via northern Europe (Air France, KLM, Lufthansa, British): 18–20 hours, mid-range prices and excellent punctuality.

The price gap between the fast routing and the cheap routing runs €150–250. If your budget rules, a long layover in São Paulo is a fair trade.

Airports: BCN and SCL

Barcelona–El Prat (BCN). Long-haul flights leave from T1; the Aerobús from the center takes 35 minutes and runs every 5–10 minutes.

Santiago – Arturo Merino Benítez (SCL). 20 km from the center: 25–35 minutes by taxi, Uber, or the Centropuerto and TurBus airport buses. It’s LATAM’s hub — if you’re continuing to San Pedro de Atacama (Calama), Patagonia (Punta Arenas) or Easter Island, that’s where those flights leave from. Leave a minimum of three hours between an international arrival and a domestic connection.

When to fly: the price calendar

Chilean seasons are inverted relative to Europe, and the austral summer (December–February) is the most expensive time of the year.

Months	Indicative fare
March–May	from €620 — the sweet spot
September–November	from €650
June–August	from €720
December–February	€900+

Watch out for Chilean national holidays (September 18): that week everything rises, domestic flights included.

Tips for paying less

Price the São Paulo routing seriously. It’s where the fare floor usually sits; compare all connections here.
Book 3–4 months out for southern-summer trips, earlier for December dates.
Fly midweek — Tuesday and Wednesday departures price lowest.
Split the domestic leg. Flights to Calama or Punta Arenas bought separately from local carriers are sometimes cheaper than adding them to the international ticket.
Mind the fare rules on stopovers: TAP’s Lisbon stopover can turn a long layover into a free extra city.

Making Santiago your base

Santiago works best as a hub with a couple of days of its own. Give the city the hill at Cerro San Cristóbal (funicular up, views of the Andes on clear mornings), the La Moneda palace and the Mercado Central for seafood lunches, and the Bellavide and Lastarria neighborhoods for evenings. The metro is cheap, fast and covers everything a visitor needs.

From Santiago, the country opens up: wine valleys 1–2 hours away by tour or rental car, Valparaíso and its hills 90 minutes on the coast, and ski resorts genuinely 45 minutes from downtown in winter. Then the big legs — Atacama in the north, Patagonia in the south — fly from SCL, which is one more reason to book the international and domestic legs as one planned itinerary.
