I spent a fair amount of time flying within Brazil and these were my observations:
- Slowest check-in lines in the world. Even if you use a kiosk (and receive one of the HORRIBLE supermarket-receipt-style boarding passes that all the Brazilian carriers issue) you have to wait in a line for bag drop that's as long as the regular check-in.
- Even the newest terminals look like they were designed in the 1980s. Look at Recife and Porto Alegre. This is the country that gave the world Oscar Niemeyer, and the best we can get is everything looking like a shopping mall did in 1987?
- Finding English speakers can be a real challenge, even at the larger international airports. Speaking Spanish was often the only way I could interact with staff.
- Boarding and baggage delivery are still more efficient than in the US. I almost always arrived at the carousel to find my bag waiting for me. I honestly cannot remember the last time that ever happened at a US airport.
Granted, I haven't been to
GRU since it was privatized, and the photos of the new terminal there look impressive. The sooner more airports get taken away from Infraero, the better. The terminal building at
CNF was wall-to-wall people, and Infraero's solution was to add more remote stands for aircraft. The terminal expansion at Fortaleza is moving at a snail's pace, and poor Vitoria and Goiania have had half-built terminals sitting there with no progress for the better part of a decade.
