Other researchers have found viruses that cause respiratory infections and the superbug MRSA, which causes skin infections. Wipe it down, use a cover, or avoid use if possible.
Cleaning crews don't have enough time to deep clean a plane between flights, especially areas that are hard to clean. Unfortunately, seatback pockets are one of those areas.
Cabin air is quite clean as it is heavily filtered, brought from outside, and changes every three minutes, but many dirty hands have touched the air vent.
Travelmath found that the vents have more bacteria than the toilet flush button. Adjust the vent with an antibacterial wipe when you first board, and don't touch it again.
Every passenger must touch the seatbelt buckle. Yet, they are seldom cleaned and are the third-germiest surface on the plane, according to Travelmath tests.
Our best advice is to clean your hands after touching your buckle. Clip a small sanitizer bottle to your personal item so it's accessible throughout the flight and after deplaning.
