Best time to fly
- High season: December–February (Argentine summer) and July–August (European holidays).
- Cheapest months: March–June and September–November, with returns from about €650–730.
- Weather note: seasons are inverted — Buenos Aires in April feels like Bilbao in October, which is exactly why shoulder-season fares are the smart buy.
Five tips for lower fares
- Compare Madrid, Paris and Amsterdam hubs — the cheapest rotates; there’s no fixed winner.
- Book 10–14 weeks out: long-haul fares to Argentina punish late bookings hardest.
- Fly midweek and avoid December’s pre-Christmas surge.
- One ticket, always: the BIO–hub leg must be protected — a self-connect with a missed long-haul is a disaster, not a bargain.
- Price domestic add-ons together: if Iguazú or Patagonia is on the itinerary, bundled LATAM/Aerolíneas legs are usually cheaper than separate purchases.
Arriving in Buenos Aires
Ezeiza is 35 km out; the Manuel Tienda León shuttle and app rides reach the centre in 45–60 minutes. Stay in Palermo for restaurants and parks, San Telmo for atmosphere, or Recoleta for the classic grand-Buenos-Aires experience. The Subte metro and abundant buses make the city cheap to move around.
Why Basques feel at home
Buenos Aires has one of the largest Basque diaspora communities in the world — Basque cultural centres, txotxo cider houses’ Argentine cousins, and a food culture that takes small plates and long meals seriously. Add in Retiro’s grand railway terminal, the Recoleta cemetery’s necropolis of the famous, weekend markets and football at La Bombonera, and a week fills itself.
Costs run well below Spain: restaurant mains, steaks especially, at a third of European prices; excellent hotels for €60–90. Research Argentina’s current card/cash practice before travel — it has changed repeatedly and materially affects your budget. Entry rules for European passport holders should also be verified before booking.
