Alcohol is the biggest factor fuelling shameful behaviour on Australian flights, including sexual activity and attacking others with foul language in front of small children.
Australian Federal Police case summaries stretching back four years show the vast majority of offensive and disorderly behaviour cases they investigated involved alcohol, according to documents obtained by a freedom of information request. 
Offending passengers were often so drunk that their questioning had to be delayed and one research organisation has called for stiffer penalties for drunk flyers.
Flight attendants confiscated vodka smuggled on board by one Japanese businessman making the 10-hour flight from Tokyo to the Gold Coast after the man's heated arguments with surrounding passengers.
The man had inappropriately touched a female passenger without her consent and spent part of the flight openly flicking through a hard-core porn magazine to the disgust of those around him.
Those watching the man said he pulled his trousers down, stuck his hand down his black tights and "engaged in vigorous hand movements".
One passenger sleeping under a blanket on another flight from Indonesia to Australia awoke to find a drunk man's urine splashing on the nearby floor and onto his blanket.
The urinating passenger was so drunk he could not be interviewed by AFP when the plane landed in Sydney hours later.
The documents showed a drunk female on one flight was ordered to pay cleaning costs after she urinated on three seats.
One passenger on another flight was forced to guard a man so he could not wander down the aisle after the drunk man urinated on a seat and left his penis out for the remainder of the flight and until police interviewed him.
Some drunken flyers also complained they were not allowed to smoke. Others lit up anyway.
Others wandered around the cabin after continuously being told by the flight crew to sit down and then fell on passengers who had remained in their seats.
