Ryanair Sues Disruptive Passenger For €3,000 Following Forced Diversion

It is a start, but when will airlines begin sharing their blocked passenger list information with each other? If you are unfit to fly on airline "A", you should be unfit to fly on any airline.
Also, I wonder if airline passengers on a flight that gets diverted, delayed, or cancelled would have any legal standing to also file a small claims charge against the person who created the problem. That could be a bigger deterrent - imagine an international flight with 300 passengers all filing a claim against someone for disruptive behavior that resulted in a day of vacation lost;hotel and car rentals wasted, etc

It's about time. Since the authorities won't or can't file criminal charges, I'm glad to see some action will be taken against them.

Land at closest suitable airport, Throw them out the door and continue the flight! They are on there own after that.
