Nobody seems to talk about this, but at both GRU and GIG people who arrive in FC on TAM are met by a personal escort who takes them through Immigration (generally avoiding the lines that other people may have) then to baggage claim where the TAM baggage handlers have IME extracted all the bags and put them on carts already (we had five bags arriving this AM, and they were all waiting for us when we arrived at baggage claim) then to customs where we were once again whisked right through. This service makes the otherwise often unpleasant experience of GRU and GIG into a pleasure. All you need is a FC arrival on TAM. The FC service on TAM is at least as good as any of the European carriers serving Brazil, IME, although not quite up to the SQ and EK level. The arrival escort makes me want to arrive on TAM when I can do it.
