My wife and I are flying BOS–GRU–GIG soon. Our tickets were purchased as a single itinerary from LATAM. As we do not speak very much Portuguese, it would help us to know what to expect as we make the connection at GRU. Specifically:
We will clear customs & immigration upon arrival in GRU, presumably. Will we need to reclaim and re-check our luggage as part of this process? If so, do we need to take our baggage to the departures hall, or is there a place near the international arrivals area to re-check bags?
It appears that we will be arriving in Terminal 3 and departing from Terminal 2 (correct me if I'm wrong here.) Is there a way to transfer airside between these terminals, or will we have to exit security in Terminal 3 and then re-enter security in Terminal 2?
