Brian Fung reports on a new study about the spread of germs in airplanes and airports, finding this interesting tidbit about the air inside an airplane:

Between drawing in clean, fresh air from outside the cabin and passing old air through high-quality filters designed to catch 99.999 percent of germs, the air inside a cabin is replaced some 20 times an hour — far more often than in office buildings or in houses, which exchange air every 12 and 5 times an hour, respectively.

Moreover planes are designed to drop the recycled air back into the same row from which it came — I had no clue. So what then did MIT find in their study? The airports are disgusting places to be, but then again we all knew that (right?). So which are the worst offenders of grime?

Leading the list: New York’s JFK International, followed by Los Angeles, Honolulu, San Francisco, Newark, and Chicago’s O’Hare and Washington’s Dulles International Airport.

Sounds like you should book your next stop in Seattle instead.
