Haha ... actually I'm here in Los Angeles right now so I know anything happens. (grin)
You never know with lawsuits. We know trial lawyers are "lefties" and litigants play on the public's bowing to political correctness. I think some of that has changed since September 11th.
As for unruly passengers (whether they are drunk, obnoxious or otherwise) yes, the airlines do sue and more frequently in recent years. And, from my experience, the airlines usually win.
As for jurisdiction, it's not where the litigant is from but I believe it is where the plane lands. Regardless, I think you and I agree these people need to be stopped. :-)
Merry Christmas!
