Crying babies, random delays, and microwave-nuked meals are just some of the reasons many of us find the whole process of jetting off to a new destination to be less than pleasant.

But what behind-the-scenes secrets do flight attendants keep hidden from their passengers?

Keep listening to find out, but might I offer you any snacks or refreshments in the meantime?

If you consider yourself a frequent flyer, you're probably so used to hearing various chimes at seemingly random times throughout the flight that you don't think twice about what they mean.

Although beeps like this, over the PA system might be followed by an announcement from the cabin crew or pilot themselves,

these chimes can also be

considered a sort of secret code between the flight deck and the cabin crew, partly to prevent

passengers from panicking. Generally, a varying number of dings can indicate a different

official message. One alone might advise attendance of some upcoming choppy air, while two usually convey that the aircraft is approaching 10,000 feet in altitude, and three can mean severe turbulence is guaranteed, advising attendance to be seated immediately.

Besides these practical and effective codes, though, pilots and attendants have also commented that these chimes might be used to communicate

private messages between the main plane and the flight deck. For example, one chime from the pilots might

mean, hey, can we have a coffee when you're free? While three from the cabin crew might tell the pilots,

we have a passenger on board with a medical issue which could require a diversion.

It's nothing out of the ordinary to look around during your flight and see most passengers dozing peacefully in their seats,

especially if your flight times aren't exactly ideal. But what if not everyone is just sleeping?

Yes, while extremely rare, all members of the cabin crew must be prepared for the unfortunate event of a natural death while thousands of feet up in the air.

But the truth is, there is no real course of action in place for this occasion, considering they can't exactly remove a corpse mid-flight.

If this does happen, the flight attendant's primary concern is to not alert other passengers

by causing a big commotion, so the best thing to do is to ensure that the deceased person

has a properly buckled seatbelt and to temporarily cover them with a blanket.

As very few planes have special lockers or body bags prepared for such

circumstances, in some cases the passenger might also be moved to first class where there are
