Having watched the video, that is one of the worst things I've ever witnessed onboard. A complete and utter bully, allowed to rampage unchallenged by crew. If a situation developed whereby someone has to stand in between two people to stop a fight, then that is the most serious situation and requires an immediate landing.
The male CC and the female CC had absolutely no authority, no presence having let this happen for a good two minutes. The male CC response to an out of control situation in the cabin was a couple of mumbled words, then challenges someone filming it a few rows back. Priorities?? The female one wasn't much better either.
Unfortunately as there's no blacklist they'll probably fly on with another airline, ready to rampage again.
FullWings - good idea, but airports make their money mainly on departing outbound passengers when they're benefitting from the holiday factor where people are more likely to spend. This will cost them, and they won't support it. Airports care not about safety. Apart from mandated security screening, once that's over the job of e airport is to extract as much cash as possible from the passengers. Nothing else.
