There's a proper etiquette that accompanies travelling on a plane - don't hog the overhead storage, always remain seated, be careful when you recline your seat, don't be loud - you get the picture. Air travel can be stressful, so these unwritten rules exist to ensure every passenger has a comfortable and enjoyable experience.
While we're busy abiding by these rules, we end up forgetting about another issue that we should really start paying more attention to - hygiene.
Between the tight seating arrangements and small lavatories, airplanes aren't the most sanitary places. Past studies have found bacteria like E.coli and MRSA on various parts of the plane including arm rests and seats, but the latest revelation will make you think twice about what you touch on planes.
TravelMath, a web-based travel resource, carried out an experiment to determine the germiest parts of airplanes and the results will have you do a double take.
The company sent a microbiologist to round-up 26 samples from four flights of two major carriers and five airports. The test results showed that most areas harbor colony-forming bacteria that could cause serious harm to one's health.
In airports, drinking fountain buttons ranked at the top followed by bathroom stall locks. As for airplanes, the lavatory flush button, seatbelt buckles, overhead air vent were a few of the dirtiest spots containing no less than 230 bacteria per cubic square inch, but surprisingly enough there's another unexpected area that took the top spot.
