Should I book through a third-party site to save money?

Finding the Best Flights to Brazil

To get the best price, book your flights 4 to 6 months in advance and prioritize flying into São Paulo (GRU) as your primary hub. Use Google Flights to track prices for at least two weeks before booking, and avoid peak travel periods like Carnival in February.

Choose your primary hub. Fly into São Paulo (GRU). It is the largest international hub in South America and almost always has the cheapest long-haul fares. You can easily book a separate, cheaper domestic flight from GRU to your final destination.
Use price tracking. Set up a Google Flights alert for your specific dates. Track prices for 14 days. If the price drops below the historical average for your route, book immediately.
Utilize airline alliances. Brazil is served heavily by LATAM, American Airlines, and United. If you have airline miles, check Oneworld or Star Alliance partners, as these often offer better value for long-haul flights into Brazil than booking directly with a single carrier.
Check secondary airports. If you are flying to Rio de Janeiro, check both Galeão (GIG) and Santos Dumont (SDU). While GIG handles international flights, sometimes a connection through GRU to SDU is cheaper.
