Do you ever get the feeling when you're flying that there's something you're not being told? There are lots of secrets hiding right under your nose in an airplane cabin. Here are 20 of the most interesting ones we could find:
1. Yes, the coffee tastes different
If you notice it's impossible to get your tea, coffee or hot chocolate to taste just right on an airplane, you're absolutely right. Because of the lower pressure in a plane's cabin, water boils at 90 degrees instead of 100.
The lower temperature means that everything made with hot water tastes "off." So maybe order a soda instead - but not a diet one.
2. Pick your dates very carefully
There are lots of tricks and strategies you can use to save money on your flight, but this is the oldest and the most reliable tip of all: plan to start your vacation on a Tuesday.
Flights are cheaper on days when there are less people flying, because airlines are trying to fill empty seats. Tuesdays, Wednesdays and Saturdays will usually give you the best deals, while Friday flights are most expensive (of course).
3. What's in a contrail?
These long white "clouds" are the subject of a lot of conspiracy theories, but in fact they're totally harmless. When warm water vapor inside your plane's engine hits the cool air outside, it condenses into the long white stream we can see from the ground.
4. Pilots never share their meals
One of the strictest rules airlines have is that pilots cannot eat the same meal or share food with each other. Why? Because they can't take the risk that both pilots get sick from their meals. Usually the lead pilot will have a First Class meal while his copilot enjoys the Business or Economy dish.
5. Those little holes on the window
No part of an airplane baffles passengers more than this. What exactly are these little holes supposed to do? Why don't they let in air from the outside of the plane?
In fact if your press your finger to the hole you can feel there's another pane of Plexiglas behind in. And a third layer behind that one. What you have here is a regular window, a backup window pane in case the outside is damaged, and an interior pane. The little hole regulates pressure, which keeps the middle pane from cracking.
