Wear a Flat-D pad when flying, you have been warned.
Several US airlines reserve the right to kick passengers off of a plane if they are have a bad odor. It’s just a line in a pages-long document known as the conditions or contract of carriage that airlines include on their websites.
Farting is benign, although awkward in close quarters. What’s worse is in airplanes, cabin pressure is lower than what we experience on the ground. Instead of being 760 mm Hg (one atmosphere), air cabin pressure mimics the pressure of being at 6,000 to 8,000 feet (1800–2400 meters) above sea level, or about 600 to 560 mm Hg. At lower pressures, gases—including those in your intestines—expand, Danish researchers explained in 2013. “This larger amount of intestinal gas will have to be released via the anus into the cabin air,” they write.
