Between 2007 and last year, there were over 28,000 unruly passenger incidents on board aircrafts in flight, according to the International Air Transport Association.
The number of unruly passenger incidents reported to IATA increased from 6,004 in 2011 to 8,217 last year, and that number likely understates the extent of the problem because many regional or smaller carriers are not IATA members.
The fact that behavior by passengers will now routinely be recorded on cell phone cameras by their fellow passengers seems to have no inhibiting effect on the unruly who threaten, curse, sexually abuse, spit at, hit, or kick those on board a plane with them.
