Thanks for the quick reply.
I am redeeming a C class award on SAA GRU/CPT but flying AA to Brasil or EZE hoped to incorporate a 3 day stop over in either GIG or EZE at the end,
am working out the mechanics since the wife is travelling with me 3 days in GIG might not be enough we have been to BA before so that layover may be more relaxing.

One thing though you did not mention if the photo/fingerprinting is done at every entry or just once?
Thanks,
mike
