Cheap flights from London to Buenos Aires

April is the cheapest month on this route, and the price calendar covers every other month as well, so you can see how the rest of the year compares before you fix your dates. Argentina's seasons run the other way round from Europe's, so April is autumn in Buenos Aires while the end of the year and the northern summer are the busy, expensive stretches on both ends. Midweek departures with one connection are usually quieter and easier to find. Book a few months ahead for peak windows; April gives you more room to leave it late.

The route has no non-stop service, so every ticket is a connecting one. Wizz Air Malta is the low-cost name in the mix. Iberia, LATAM Airlines, Latam Airlines Brasil, United Airlines, Austrian, Brussels Airlines, Royal Air Maroc and BA EuroFlyer are the full-service carriers you will see quoted. What differs most is what comes with the ticket: low-cost fares are built around hand luggage, with anything checked added on, while full-service tickets vary from fare to fare, so read the small print instead of assuming. Check connection times too — a short stop can look fine on paper and feel tight on the day.

Flights land at one of two airports: Jorge Newbery, which sits close to the centre on the river side, or Pistarini, which is well outside the city and needs a longer transfer. Which one you get depends on your airline and your connection, so confirm it before you arrange a pickup. Taxis, ride-hailing apps and airport buses all run into town; agree the fare or use the app before you get in, and have a card that works abroad or some local cash for the ride. If you land late, sort your transfer in advance rather than at the kerb.
