Another smoker checks in. While I never would consider smoking around a non smoker, even when they say it's OK, I think the owner of the aircraft should have the choice. Since 80% or so of the people in the western world do not smoke, The end result would have to be the same. However, if an airline did choose to allow smoking, what right does a government have saying this is illegal. I wouldn't fly it but I will never own an airline either. I can happily go without a cigarette as long as I am doing something more important.
BTW, no aircraft has ever caught fire as a result of legal smoking on board.
