Incidents of unruly passenger behavior are increasing aboard commercial flights. That's the finding of a new airline industry report which found a 14-percent year-to-year increase in incidents of passengers gone wild.

Most of the incidents involve verbal abuse, failure to follow instructions, and general antisocial behavior. Eleven-percent involve physical aggression toward passengers or crew, or damage to the aircraft itself. The report adds that alcohol or drug intoxication is a factor in about a quarter of the cases.

The report, from the International Air Transport Association claims most of these cases involved people who boarded the flight drunk or high.

If you're an airline professional like a flight attendant or commercial pilot,or even just a frequent flier, what are you experiencing in the air? Are passengers generally acting out more? If so, what do you think is the reason? Have you seen a particular notable episode of threatening behavior by a fellow passenger? How was it handled?
