Alcohol is not the issue, it's the behaviour of a tiny minority of people when they take it. I always have 2 or 3 whiskeys when flying long haul (assuming I don't have to drive when arriving), then promptly fall asleep, and I've never caused anybody any trouble. Some people are just violent, no doubt alcohol exacerbates this trait in them, but to punish us all by removing alcohol entirely is unfair. To those of you stating that you have never taken alcohol, I commend you, doubtless your long term health will be better as a result, but please don't harrangue the vast majority of the human population who use alcohol reponsibly
