Great...now I will never have to ask if a flight is non-smoking. Since I have only flown DL or its partners on internation though, this hasn't been a problem since 1994.

Up until I started reading this board, I thought it was fine for airlines to have smoking cabins as long as they were completely seperate from the non-smoking cabin. But after reading posts on this board, I now realize that air quality was only part of it. Smoking creates a fire hazard and that is dangerous - even if you are out on the wing.
