Though this is undoubtedly truly awful, I cannot see a good outcome from your husband going to see this captain on Volkan 4. What can he achieve? I can understand the wanting to hurt him part, but I think as you could not make an official complaint at the time, I cannot see how this would get you any more forward and could even end up with your hubby in trouble.
Let us get this b****** through social media, this is a very powerful way.......
Just a pity you did not have the time to complain before you left.
