Our flight was delayed by 2 hours late last night in Barcelona.
One passenger was with his partner. He was getting agitated that the flight was so delayed and taking it out verbally with his gf.
He was so passive aggressive.
I really felt for the woman. I just wanted to tell her that she doesn't need to put up with it.
She actually apologised to him.
The second was on the flight. A youngish couple. Early 20's sat down and she had been drinking. She started hitting him and trying to get his mobile. This went on whilst we were taking off so the man was trapped.
2 grown men behind thought it was hilarious. 
I went and told the cabin crew that this passenger was drunk and emotional and kept assaulting her partner.
They couldn't have cared less. I said if it was the other way round you would view this differently.
Horrible flight all round.
I had years of DV when I was younger and I always felt that nobody ever helped me or stepped in.
People used to turn a blind eye.
