The question isn't who farts, it's who doesn't fart on a plane (and the answer is nobody.) It's a combination of the pressure, the long stretches sitting, the jostling of the plane, and the way you deviate from your normal diet when you travel.

Go easy on meat and dairy for 12-24 hours before you fly, and avoid beans, soda, onions, cabbage, cashews, and whatever else makes you fart or makes your farts stink worse. Don't eat a lot of fat or sweets before you get on the plane -- no airport terminal Cinnabon, no Big Mac. Take some simethicone once you've boarded the plane, either by itself or in a tablet like Gas-X.

Not only will you fart less, you'll feel less logy and bloated and out of sorts when you arrive.
