The only small hitch was testing kiosk check-in for my Rio Santos Dumont (SDU) – São Paulo Congonhas (CGH) on Tam. Screen after screen after screen, all requiring information, and in the end it said we could not check-in, presumably because it was a United award ticket.
I had apprehensions of flying Tam from many times seeing their unmoving check-in lines in Miami snaking across multiple terminals, yet at Santos Dumont there was no line to the smiling agent, who said the magical words, “Would you like an earlier flight?” The Rio-São Paulo shuttle runs constantly and we zipped up to the earlier flight.
The short flight matched the Gol shuttle for comfort and quality service.
From what I hear, like for Gol, the Rio-São Paulo shuttle experience is in no way representative of any other Tam flight.
