I think what spongebob was getting at was the article which mentioned a passenger being restrained, not your post. This concerned me as well because when I was at Air 2000, we had breakaway training but not restraint because, as mentioned, they do not carry restraint kits.
Have restraint kits been introduced or is the article incorrect? I do recall an incident many years ago when Air 2000 were doing an Aliltalia contract where they had to restrain a passenger with headsets. Maybe the crew in this article improvised as well?
