Finding Cheap Flights To Iguazu Falls

Iguazu Falls is served by two airports on either side of the border: Cataratas del Iguazú International Airport (IGR) in Argentina and Foz do Iguaçu International Airport (IGU) in Brazil. This unique dual-airport system allows travelers to compare arrival options from two countries, often leading to competitive fares for domestic flights within Argentina or Brazil into the falls, as well as key regional connections.

Travelers flying into the Iguazu region will find the most frequent and affordable service from the respective national capitals. Into IGR (Argentina), the top route is from Buenos Aires (AEP/EZE). Into IGU (Brazil), the primary routes are from São Paulo (GRU/CGH) and Rio de Janeiro. Direct regional arrivals from other tourist hubs like Lima, Santiago, and Asunción are also available into the area.

The market into Iguazu Falls is served by a mix of national carriers and regional airlines. Aerolíneas Argentinas and JetSMART dominate arrivals on the Argentine side (IGR), while LATAM, GOL, and Azul operate into the Brazilian side (IGU). This cross-border competition provides opportunities for savvy travelers to check both airports for the best deal when flying to the falls.

To secure cheap flights to Iguazu Falls, always check fares into both IGR and IGU airports, as prices can vary significantly. Book domestic flights within Argentina or Brazil into the falls at least 2-3 weeks in advance. For international regional arrivals into Iguazu, booking a month or more ahead is advisable. Due to the airports' focus on tourism, mid-week arrivals can be cheaper than weekend landings.
