Cheap flights from Warsaw to Iguassu Falls

November is the cheapest month on this route, and fares stay worth watching from September through February. That window covers the Brazilian spring and summer, so expect warm, humid days and the falls carrying plenty of water, along with the December and January holiday rush, when seats go early and prices climb. Book well ahead for travel around Christmas and New Year, and again for the Polish school holidays in summer. Midweek departures, Tuesday and Wednesday in particular, are usually quieter and cheaper than weekend ones, and a midweek return gives you the same advantage.

No airline on this list flies Warsaw to Iguassu Falls non-stop, so every option is a connecting itinerary. TAP Portugal, KLM Royal Dutch Airlines, Air France, Finnair, Lufthansa Cityline, Turkish Airlines and Qatar Airways are full-service carriers, where the fare you buy usually bundles more than a seat and a hand bag. HOP! is Air France's regional arm, and Air Baltic is a hybrid, with the cheapest fares tending to be hand baggage only. LOT Polish Airlines is the home carrier, handy if you prefer to start with a short hop from Warsaw. What is actually included depends on the fare class rather than the airline, so read the baggage and change rules on the exact ticket.

You land at Cataratas, the airport on the Brazilian side of Iguassu Falls. It is a compact terminal that sits close to the falls themselves rather than out in the countryside, and the nearest town centre is a short drive away. Taxis and app-based rides wait outside arrivals, and local buses run into town for anyone travelling light. Many hotels in the area run their own shuttles, so it is worth asking before you arrive. The Argentine side of the falls is a separate trip across the border, which means carrying your passport and checking entry rules for your nationality in advance.

Country facts: Wikidata

• Check whether you are flying from F. Chopin or Modlin, because Warsaw's two airports are not interchangeable.
• Look at the baggage allowance on the cheapest fare, since hybrid and low-cost tickets often include hand baggage only.
• If your trip is built from separate tickets, leave a long gap at the connecting airport, as a missed connection is then yours to solve.
• Confirm Brazil's entry rules for your nationality, including passport validity and any visa you need.
• Book early for December and January travel, when the cheapest month has passed and seats fill quickly.
• Decide which side of the falls you want to see first, as the Brazilian and Argentine sides are visited separately.
