I can't remember being on a flight with any incidents caused by passengers drinking themselves into unruly behaviour.
Perhaps I've been lucky or perhaps I not been seated close enough to any to really notice.

And yes, I have been a very regular flyer for over 35 years. Mostly long-haul.

I'm not suggesting it doesn't happen. We all know that it does happen, often creating newspaper headlines or even TV news. Especially if it's someone with celeb status.

Personally, I've always enjoyed a wine and beer or if I'm lucky champers. Long may that continue.

I know that airline staff do actually perform 'profile risk assessments' before boarding, and probably catch quite a few who are actually prevented from boarding.
Once on board the staff are able to control the quantity of alcohol by limiting the amount given each time they serve you and the number of times they serve you.

The one thing thay cannot control is the amount of alcohol actually consumed surreptitiously by those who bring on their own supply and will eventually display obnoxious and drunken behaviour.
Apart from that there are plenty of folks who bring on board bottles and bottles of duty free. So there is yet another supply.

Let's make no mistake it's not an easy task to deal with inebriated unruly people at the best of times.
When it occurs on board an aeroplane the challenges and hazards to restrain and control the culprit and to protect other passenger increase exponetially

It's quite easy to monitor, control and identify those who defy a smoking ban.
How could the same be held for a ban on drinking alcohol?
How about those who despite an alcohol ban turn to some form of drugs?

If conditions cause a total ban, that would for me deprive me of some enjoyment. I'd accept it of course, no choice, but I ask is there perhaps a less extreme solution.?

As with drink-related individual driving bans, why not a drink-related individual flying ban?
