I remember those Dan Air flights with my parents in the early 80s - always shovelled to the back so my mum could smoke.

They always turned the smoking signs of just after take off "Ladies and gentlemen you may now smoke if you wish......"

There's a great no smoking pub on Threadneedle Street in London - it's utterly amazing how different it is. The worst part of coming home from a normal pub is all your clothes smelling of fags.
