I remember when you could buy cigarettes on a flight.I am a smoker and don't really have a problem with not smoking on flights.I will say that it was a joy some 4 years ago to be able to smoke on air france 747 flight,par-hkg.They had the rl door area curtained off and a vent valve fitted.I had 3 smokes on the 12 hr flight.Just enough to keep the nico fix at bay.I think airlines should look at an option,especially for crew.Good point!
