The Emirates flight to Rio from Buenos Aires was excellent. The flight is on a new Boeing 777-200. As soon as we sat down we were handed a hot towel. The ceiling has star led lights. There were over 200 movies to choose from and at least as many TV shows.
In general flying outside the US has been a lot easier. No TSA to deal with.
Also there is a photo of BA airport, pictures of Brad pit hanging everywhere. Quite funny.
