To be quite honest I haven't noticed where the smokers go to smoke in airports. I agree that there should be areas where smokers can smoke away from others. I have a problem with smokers getting a non-smoking room and then smoke in it. As stated by several others they do not like the smell in a smoking room or on planes in the smoking areas when smoking was allowed.

From watching my parents and others certain things seemed to trigger their need to smoke: 1. Knowing you can not smoke made it worse. 2. Needing to smoke after a meal even on a plane. 3. Waking up from a nap or long period of rest. 4. The smell of smoke. 5. A type A personality. These are just some of the things my parents and friends have said triggers their need to smoke.

Each to their own.
