As a non-smoker, I don't support the idea. Making it easier for those who smoke, may effectively puts those who don't in an uncomfortable position. If you 'promote' smoking areas in airports then this could make it more unpleasant for non-smokers who may be sat next to you on an aircraft with the associated smells. Although I understand the forum is intended to make it easier for those who do smoke, there are wider implications that should be considered.
