2unlimited, I take it your're a non-drinker? Don't forget that there is a actually a very large majority of people who drink in sensible moderation. For that reason I would never support a ban on alcohol at airports or on flights. I do however advocate a strict no-fly regulation for any passengers who are obviously plastered and extremely rowdy prior to boarding. There's also the question of how to enforce drinking limits once on board flights when there are many (from Hen or Stag parties) who begin to consume alcohol purchased at the airport Duty Free.
