I flew Varig Business Class last Christmas/New Years on the route Fankfurt-Sao Paulo-Rio de Janeiro, and Rio de Janeiro-Paris on yje way back.
The seats where very comfy (at least in Buisness Class), but it looked rather nice back in coach too!!
Food where really great, some of the best I´ve ever eaten on an airplane!
Entertainment was good to!
The F/A where friendly, although they didn´t inform us at all after a HUGE drop!!
But I can definitly recommend Varig, they are really safe to, thats for sure!
Have a nice trip!
