Just a heads up for those traveling to/thru GRU... it's an absolute nightmare.
Was flying on TAM from Salvador (SSA) to GRU to connect to Miami... the traffic is so bad that the TAM flight was an ahour and a half late and i was bumped to another connecting flight. I actually made it 50 minutes prior to boarding, but the security line was about 1000 people long (I am not exaggerating)... but it went relatively fast... was through in about 50 minutes... had it been a US airport it would have been 5 hours.
Until everything is worked out with Congonhas, i suggest staying away from GRU unless you have a big layover time or have no other choice.
