'Revealed' airline secrets are horrifying

So ... we've got a not-so-awesome airline "secret" to reveal. The "TODAY" show reports pillows and blankets apparently aren't washed between flights. Ew.

They apparently just put another bag around an old blanket and seal it up.

Another "secret" that's a lot less gnarly? Turns out, you can also be upgraded to first class DURING the flight.

'One flight attendant says it helps if you're very nice, pregnant, tall or good looking, or all of the above.'

We should point out - all these claims initially started on Reddit. A user asked airline insiders to spill any secrets they knew. Of course, the airlines haven't confirmed any of these less-than-flattering statements.

The Huffington Post draws attention to another potential dirty secret on the list: there's a chance your tray table has ... poop on it.

'You have more than likely ingested baby poo. I saw more dirty diapers laid out on those trays than food. And those trays, yeah, never saw them cleaned or sanitized once.'

Well, we're definitely going to pack 1,000 sanitizing wipes next time we fly.

Viral Quake gathered some other disturbing tidbits from Reddit users. One warned people NOT to drink the water in the airplane's bathroom.

'It is bad enough to 'wash' your hands in it. We sanitize the water tank at selected maintenance intervals, however parasites build tolerances to these cleaners.'

And The Star points out another revelation from Reddit users - apparently the pilot and co-pilot are actually served different sets of meals, just to be safe.

We wouldn't want them both coming down with food poisoning.

Some of the other secrets? You can actually request the entire can of soda instead of just a cupful. And ... people have a tendency to steal the life jackets. Now that's just rude.
