Myth about Airplanes
The most dangerous health hazard in the air is the cabin air itself
The cabin air is fine and aircraft are outfitted with HEPA filters to clean it. The real problems lie on the chair upholstery, the tray table, the armrests and the toilet handle, where bacteria such as methicillinresistant Staphylococcus aureus (MRSA) and E. coli can live for up to a week on airplanes that arent properly cleaned.
