10. You've never experienced extreme turbulence
More than 2 million people fly in the United States each day, and yet since 1980, only three people have died as a direct result of turbulence. Of those fatalities, two passengers weren't wearing their safety belts. During that same time period, the Federal Aviation Administration recorded just over 300 serious injuries from turbulence, and more than two-thirds of the victims were flight attendants. What do these numbers mean? As long as your seat belt is on, you're more likely to be injured by falling luggage than by choppy air.
Interestingly, on some airlines, a flight attendant's injuries in flight can't be officially classified as an on-duty injury unless it happens during what's known as "extreme turbulence" — where the captain loses control of the plane or the craft sustains structural damage. In both of those cases, the aircraft must be grounded and inspected. Because no one wants to ground a plane, captains are very hesitant to hand out the "extreme turbulence" label. A friend of mine who works closely with airline management said he's never seen a pilot label rough air as "extreme turbulence." So the next time you're nervous about some mid-flight bumps, just take a deep breath and remind yourself, "This isn't extreme!"
