Overview

• Reduced cabin pressure at cruising altitude expands intestinal gas by loosening trapped air in the gut and leads to more frequent flatulence
• Early studies in 2005 and 2013 found that activated carbon fibers in underwear and proposed seat fabrics can adsorb odorous sulfur gases
• Airbus maintains its ventilation system replaces all cabin air every two to three minutes and considers additional filters unnecessary
• Lufthansa reports no specific policy on onboard flatulence while Turkish Airlines advises herbal tea instead of caffeine and slow eating to prevent excess gas
• Gastroenterologists recommend avoiding heavy or carbonated meals before flying and suggest aisle walking and abdominal massage to relieve pressure
