TAM, no contest. It's a real airline. If you've seen the series "Airline", consider it depicts GOL instead of Southwest, but in too classy a way. GOL is no Jetblue, but an even more vulgar Southwest. (Yes, it can be done). Expect situations where people board with large snakes, rince their glass eyes in their drinks, leave soiled paper on the side of the toilet and not in it, walk away with the safety card, light up before landing, put babies to sleep in overhead bins... etc. A real course in some stranger sides of civilization down in Samba land.
