The Banco Safra Lounge, which was the former Star Alliance lounge, is located in Terminal 3 of the Aeroporto Internacional de São Paulo-Guarulhos. Terminal 3 is the newest terminal at the airport and is exclusively for international operations, handling nearly all flights from North America, Europe, and Africa.

The lounge does also welcome passengers in premium cabins flying with ITA Airways and Emirates, and, for part of the day, Priority Pass members. Priority Pass access is limited to the hours of 23:00 to 14:00 and, as my flight was at 07:15 yesterday, I chose to visit the Banco Safra Lounge as I knew its food offering was better than the other two priority pass lounges in the terminal.
