The New Zealand Medical Journal has published an article warning of the dangers of flatulence on planes.
The article, Flatulence on airplanes: Just let it go, was written by Danish researchers who recommend airlines introduce odour absorbing layers in seats to combat the passing of wind aloft.
The researchers said cramped conditions, pressure changes and air recycling on board planes all conspire to make farting more of a problem in the air than at ground level.
They also warn that passing wind in the cockpit could compromise safety by distracting the pilot, while holding gas in can cause pain and discomfort.
The article even suggests airlines should split planes into sections with people prone to flatulence sitting closer to toilets.
It also says companies could develop seat cushions and clothing with odour absorbing layers of activated charcoal specifically for flying.
