Gosh, if you want to see drunk obnoxious people try flying to Punta Cana, I frequently see groups of people standing around shouting their heads off and getting drunk. When it gets too much I have a quiet word with the cabin manager and it always gets sorted out. I wonder if the airline will give any further compensation to be honest - they did take remedial action by changing seats and presumably telling the drunken lady to shut up, and they did give a bottle of champagne. I'm not sure what else they were expected to do.

I get that the OP is very upset, but I think he should realise that he shouldn't have moved seats in the first place. Those middle seats in old J are like a Wendy-house (at least in my mind) they form a little cabin, very protected from the outside. None of this would have happened had he stayed sitting next to his wife, sure the passenger would have been drunk on the other side of the dividing wall, but crew are very used to dealing with drunk passengers and would have sorted it. It would have been impossible for her to pour wine into the lady's mouth, touch controls or anything else. Instead he went off to a different seat, leaving his wife to the mercy of whoever the airline chose to plonk next to her and in this case it was the passenger from hell. He assumed that because those seats were empty they would remain so, and this was a mistake. I'm honestly not victim blaming, but if my husband had done that to me, he would be out shopping for a new pair of goolies today.
