GRU transit: duty free?
OK, next week I am doing a transfer from Delta ATL-GRU to Gol GRU-MVD, and back again in a few days. I'll have two hours layover on the way there and six glorious hours on the way back. I have no visa so I'll have to stay airside. As a Delta Diamond in Business Class, I believe I'll be able to experience the joys of the GOL Smiles Lounge, such as it is, in Terminal 2.
I wanted to ask about duty free, something I haven't found a clear answer to. Are duty-free areas in the GRU airport accessible to transit-only passengers? Thanks.
