From next year there'll be no smoking in any airport in the UK anyway, will there?
At Dublin there are always loads of pax hanging outside having their cigarettes before going through boarding - quite sheltered too.
There was a bit of a kick up over here a while ago about some sort of smoking area they have put on the airside. It was in the paper that it was put in for the American soldiers going through Shannon to/from Iraq and elsewhere! Presume it's still there.
I remember being in Washington airport just over 3 years ago and waiting for another flight. Eventhough the airport was non-smoking there was a big smoking room beside one of the bars and you could have a cigarette there eventhough I was too young to drink over there.
