I'm flying from Rio to Iguacu Falls on Monday, 3 October, unfortunately the itinerary involving a transfer from CGH to GRU was the only sensible option time and price wise. I'll arrive at CGH on LATAM at 11:45am, departure from GRU is at 16:20. I understand that LATAM offers a shuttle bus every hour, but I don't see that I can reach the 12pm departure. Or do the shuttle busses tend to run a bit late? Would the 1pm shuttle bus still be sufficient to arrive in GRU on time? If not, are there any other busses or would I have to take a taxi? Can someone share any recent experiences with the shuttle bus or the transfer in general? And is there anything else I should keep in mind? Thanks a lot for your advice!
