What is the smoking situation on Brazilian domestic airline flights these days? Hopefully completely banned? I visited Brazil in 1987. Back in those days international flights had a smoking section (usually at the back of the plane) and a non-smoking section. So of course the domestic carriers also did the same (TransBrasil in this case). But with a slight change: left side of plane was smoking, right side of plane was non-smoking. As Dave Barry would say: "I am not making this up!".
