How long is the flight from Buenos Aires to Madrid?

A direct flight between Buenos Aires and Madrid takes about 11 hours 50 minutes on average outbound, based on route schedule data (FlightsFrom, Skyscanner, FlightConnections, Expedia):

  • Iberia (Airbus A350): ~11 h 50–12 h 15. The airline with the most frequency on the route.
  • Aerolíneas Argentinas (Airbus A330, SkyTeam): around 11 h 50–12 h 10.
  • Air Europa: around 12 h, depending on aircraft and winds.

One detail worth knowing: because the outbound leg flies east with the jet stream at its back, EZE → MAD is clearly faster than the return MAD → EZE, which faces headwinds and usually runs 12 h 45–13 h 05. The fastest recorded nonstop is around 11 hours 30 minutes. If you connect (via São Paulo, Lima, or a European capital), total travel time can climb to 16–20 hours — so on a route this long, the nonstop almost always wins, saving hours and, often, money.

Which airlines fly the route (and which are cheapest)

Three airlines dominate the nonstop between Ezeiza and Barajas, and that competition is great news for your wallet:

  • Iberia — Spain’s flag carrier (Oneworld) and the airline with the most nonstops on the route, flying the Airbus A350. Solid economy fares and smooth onward connections across Europe through Madrid.
  • Aerolíneas Argentinas — Argentina’s flag carrier (SkyTeam), flying the Airbus A330. Usually includes baggage; ideal for nonstop schedules with no stops.
  • Air Europa — also a SkyTeam member, and frequently the cheapest, especially in economy and booked in advance.

In addition, Plus Ultra (more limited frequencies) and LATAM (Boeing 787, often with a connection) also operate the route. On certain dates, connecting options (Air France, KLM, via São Paulo) can surface at competitive prices, but they add a stop and time.

Golden rule: comparing all the nonstops at once makes the difference. Before you book, compare every Buenos Aires–Madrid flight on TopTravelCentre to see instantly which airline is cheapest for your dates.

Airports: Ezeiza (EZE) and Madrid-Barajas (MAD)

Picking the right airport and terminal saves money and headaches.

Buenos Aires – Ezeiza / Ministro Pistarini (EZE)

Buenos Aires’ long-haul airport, about 22 km southwest of downtown. Confirm you’re departing from Ezeiza, not Aeroparque (AEP): Aeroparque handles mostly domestic and regional flights, while all Madrid traffic leaves from EZE. Arrive early, because traffic and security lines are unpredictable. If your origin is another Argentine city (Córdoba, Mendoza, Rosario), weigh whether a domestic flight + a nonstop from EZE beats a connecting itinerary.

Madrid-Barajas – Adolfo Suárez (MAD)

The main gateway to Spain and Europe. T4/T4S is Iberia’s base; T1 typically receives Air Europa and Aerolíneas Argentinas. Confirm your terminal on aena.es before booking ground transport, because the terminals are far apart. The metro and the Cercanías train (C10) connect Barajas to the center in ~40 min.

Often-forgotten tip: if you’ll continue to another European city, Iberia and Air Europa offer connecting tickets from Madrid; sometimes a single Ezeiza–Madrid–Paris ticket costs less than buying the legs separately.

When is the cheapest time to fly to Madrid?

Search engines (Skyscanner, KAYAK, Expedia, momondo) agree on the lowest-demand months:

  • November, December and March — the best windows. November and December show up as the cheapest months on Skyscanner, and March is typically ~15% cheaper than the yearly average per Expedia.
  • April–May and September–October — shoulder season: good weather in Madrid and reasonable prices.

When to avoid: June, July and August (peak European summer), plus Christmas, New Year and Easter. Demand pushes prices up and nonstop seats sell out. Flying Tuesday, Wednesday or Saturday is usually cheaper; if summer is your only option, book several months ahead.

7 real tactics to get the cheapest flight

  1. Aim for November, December or March. The cheapest months of the year on this route.
  2. Book 2–4 months ahead. On transatlantic routes that’s the sweet spot: not a year out, not last-minute. (Learn more in our guide on how far in advance to book a flight.)
  3. Round trip, almost always. Usually cheaper than two one-ways, and sometimes unlocks better fare classes.
  4. Compare Iberia, Aerolíneas Argentinas and Air Europa. The three nonstops compete: Air Europa often sets the price floor.
  5. Stay flexible on dates. Shifting by a week or flying midweek can save 15–30% on transatlantic fares.
  6. Watch the layover. A stop via São Paulo or Lima can look cheap but adds time and possible delays; here the nonstop is usually very competitive.
  7. Use a metasearch that groups every airline. The fastest way to never miss a deal. For more tactics, read our tips to find cheap flights that actually work.

How much does a Buenos Aires–Madrid flight cost? (price ranges)

Prices change daily, so here are indicative ranges with the consultation date. As a long-haul transatlantic route, it’s considerably pricier than a short European hop, and from Argentina long-haul fares are quoted in US dollars (USD) — that’s your reliable anchor; the peso (ARS) equivalent moves with the exchange rate, so treat it as a reference.

Checked on 06/08/2026. In offer windows (November, December and March), with Air Europa or Iberia and early booking, a round-trip EZE–MAD in economy typically starts from ~USD 790–950 (Iberia from about USD 791; Aerolíneas Argentinas from about USD 950), within a normal low-season range of ~USD 900–1,250. Connecting options (Air France via Europe) can drop to ~USD 470–660 on certain dates, in exchange for a stop. In peak season (June–August, Christmas, Easter) or last-minute, that same nonstop can exceed USD 1,400. As an indicative peso reference: Iberia around ARS 1,224,000 and KAYAK from ARS 864,849, but ARS fluctuates with the exchange rate. These are ranges, not guaranteed prices: always check the live fare for your dates before booking.
