United will be serving Brazil from their international hubs in Washington Dulles and Chicago. The service from MIA
has its days numbered.
From the airlines that serve the route and that I've been on, United was the best one, better then Varig or American, mostly because of the individual entertainment system UAL has. TAM has that too in their A330s, and its service in Brazil is great, so I'm guessing TAM's service can beat United. But as far as Varig and American are concern, no way. Oh, there's Continental too, I don't know about them either (they fly from Newark and Houston to Rio and Sao Paulo). Varig flyes from MIA
, TAM only from MIA
and American from MIA
, and JFK
United's service to Brazil is pretty good.
