Good idea or bad?

Banning it completely doesn't make much sense when you consider the smoke from the traffic and the jet engines, but the other passengers shouldn't have to share it. I know there are security restrictions, but a smokers room could be allocated, it just has to be well ventilated. They'd be better off banning alcohol.

I agree with pokkets. A total ban leads to more stressed out people, and who wants to fly with people like that.
