Cheap flights from London to Santiago

March comes out cheapest on this route, which lines up with late summer in Chile and the last stretch of winter in London, so you get warm days in Santiago without peak-season fares. September and October are also worth watching. December and January are the priciest months, thanks to Christmas, New Year and the southern summer holidays. Flying midweek usually costs less than a weekend departure, and Tuesday to Thursday tends to be the quietest. Book a few months ahead for the southern summer window, and check the whole price calendar before you commit.

Nothing flies non-stop between London and Santiago, so every itinerary on this route is a connecting one. Easyjet, Wizz Air UK, Wizz Air Malta and Vueling Airlines are the low-cost names in the mix. Air France, Iberia, Austrian, Aer Lingus, United Airlines and AeroMéxico are the full-service carriers. The difference matters at booking: low-cost fares generally come with less included, so check baggage and seat rules, while full-service tickets often bundle more but still vary by fare family. Compare the total, not just the headline fare.

Every flight lands at Arturo Merino Benitez, the airport serving Santiago, and it sits outside the city rather than in the centre. Taxis and ride-hailing apps are the direct way in, while shared shuttles and airport buses cost less if you are not in a hurry. Traffic builds in the morning and evening peaks, so leave room if you have an onward domestic flight. If your itinerary touches another South American city first, check whether you clear immigration there or on arrival in Chile, and keep your onward booking to hand.
