Flight Attendants Share Fascinating Details About Airplane Travel That Few Passengers Are Aware Of

Thousands of commercial flights transport passengers all over the world every day. And while soaring through the sky at hundreds of miles an hour seems like a dangerous way to get from one place to another, the men and women who work onboard these flights are highly trained to handle any type of emergency.

So it's safe to say that airline employees know everything that occurs behind the scenes… things the public would have no idea about. Luckily, these pilots and flight attendants decided to spill the beans on 20 fascinating secrets about flying!

1. Anyone who's flown in an airplane knows about the "stow portable electronic devices" rule, but do they know why? Cell phones can interfere with air traffic control frequencies, which can be an issue during the takeoff and landing. Also, in the event of an emergency, electronic equipment can become projectiles!
2. Automatic upgrades to a higher class don't happen very frequently. However, according to one flight attendant, they're pretty much done at the crew's discretion and can happen for a number of reasons. Passengers might be upgraded if they're kind, obviously pregnant, good-looking, or even a friend of a crew member.
3. The most annoying beverage for flight attendants to pour is Diet Coke. Because of the extreme amount of carbonation and the plane's altitude, the liquid takes about three times as long to settle in the cup. This significantly cuts into the attendants' service time.
4. The first order of business for a flight attendant is his or her professional duties, of course. Still, there's no rule that prevents them from fraternizing with the passengers—and possibly finding a romantic connection with one of them!
