Wow, never would have thought there would be a question about drinking while flying. Plain stupid in my opinion. Afterwords is an entirely different matter to me though. Just please don't make so much noise from your campsite that you wake me up!

Seriously, after the flying is done, it should come down to site rules and responsible behavior. If you know you'll get rowdy or be tempted to get out a plane again after you've had a few, then don't even bring it. Too bad common sense isn't so common anymore.
