Pros: Excellent flight crews. Airports in Vitoria and Sao Paulo and personnel friendly, easy to get around with signs. Airport in Sao Paulo is HUGE - do not schedule your flights too close together and go directly to your gates immediately - it can take 1 to 2 hours or more (depending on security, airline, and customs) to move from international to domestic and vice-versa. Be prepared to wait wait wait in lines. It is all very organized and efficient, but the shear distances are amazing. You will do a LOT of walking/running dragging luggage.
Cons: Latam had older aircraft, seats not so comfortable on flight from Vitoria to Sao Paulo.
