Well, to my surprise I flew so many times TAM economy from MIA-GRU and was so well treated and comfy, I would not even want to fly first class. No joke now, the first time I was going to fly intercontinental as a passenger in TAM I really had the "ah, just gonna be another crap 7 hours in a crappy airline" oh boy was I wrong. TAM economy in my opinion much better than BA, Swiss, TAP, any of the American Airliners obviously and so forth. Oh sorry, got a little off topic here, but I just had to mention how amazed I was flying TAM economy. Roomy, good food, happy and helpful flight attendants (the ones that speak with a softer voice and are proud to fly internationally and not hating it like so many these days). The flight entertainment system was pretty much 0 but I read books or take a sleeping pill in flights anyway that last more than 6 hours.
