I fly back and forth to Hawaii a minimum of 8x a year, these flights tend to have more of a party atmosphere than say a flight SFO-ORD. Even on the AM flights people tend to start the day off with a champagne or Mimosa and continue with MaiTais, etc. (most are starting a well earned vacation). In the course of this 5+ hour flight I have never seen anyone get visibly drunk or disruptive,(much less storm the cockpit) I think this whole issue is way overblown.
