São Paulo/Guarulhos International Airport (GRU)

Connecting through São Paulo Guarulhos International Airport (GRU) requires an understanding of the terminal layout and Brazilian customs regulations. The airport primarily uses Terminal 2 for domestic and some regional flights, while Terminal 3 is the main hub for long-haul international departures. If you are arriving on an international flight and connecting to a domestic destination within Brazil, you must clear immigration, collect your checked baggage, and pass through customs at GRU, even if your luggage is tagged to your final destination. After customs, you can use the 'Baggage Drop' counters to re-check your bags before moving to the domestic gates in Terminal 2.

For international-to-international transfers on a single ticket, you can usually stay airside and use the connecting corridor between Terminal 2 and Terminal 3. This walk takes approximately 10 to 15 minutes; follow the red floor tiles to reach Terminal 3 or the black tiles for Terminal 2. If your journey involves separate tickets, or if you are flying with Azul (which often uses the isolated Terminal 1), you will need to exit the secure area and use the free circular shuttle bus that runs between all three terminals every 15 to 20 minutes.

A minimum connection time of 3.5 hours is recommended for international arrivals connecting to domestic flights due to potential queues at immigration and the baggage re-check process. For domestic to international connections, 2.5 hours is typically sufficient if your bags are checked through. Be aware that most premium lounges are located in Terminal 3, so travelers with long layovers in Terminal 2 may wish to walk to Terminal 3 to access these facilities, keeping in mind the return walk to their departure gate.
