Semi-Elite -- I never said anything about approving or disapproving. I was merely making the observation that I can't imagine why someone would want to drink that much on a plane. What does flying have to do with drinking booze?

There are many other activities that one does during the course of the day that does not involve drinking alcohol -- taking a bus, going to the movies, going to work...

Maybe you're right and it is considered part of the in-flight entertainment, or a sedative to tolerate tight seating...

I've never seen anyone drink alcohol at 7 in the morning, except on a plane (maybe also in my college years, but that was because we never went to sleep...). I just find it a bit strange, but I'm not proposing anything be outlawed or banned.
