Another interesting point is that this concept of allowing pax to serve themselves booze, is in DIRECT contradiction to a disruptive passenger/hijacking video made by Air New Zealand and used by various other airlines.
Why not go all the way, and let pax serve themselves their meals?
I'm sure the cabin crew wouldn't object to that!
Not much chance of reducing F/A numbers, TIMMEEEE, I think they're down to the legal minimum on most flights already.
