10 Best Kept Secrets About Airlines That You Didn't Know About!

From the headphones to the coffee, there is a lot that you don't know about the airlines you fly in. You may have been bitten by wanderlust bug, but that shouldn't stop you from knowing what no one has ever told you about airports!

In a recent discussion thread on the social-networking website called Reddit, many users offered a range of insights that might actually help you on your next trip.

Here are a few tips and tricks that we picked up from the conversation

Ps: Bon voyage

1. The oxygen masks that you hear about in the security announcement have about 15 minutes of oxygen in them from the point of pulling them down. Yes, you got that right! But in usual circumstances this is more than enough time for the pilot you to a lower altitude where you can actually breathe normally.

2. The real reason why the lights on the airplane are dim when landing at night, is that they dim the interior lights in case you need to evacuate upon landing. In this way, your eyes are already adjusted to the darkness around you and you'll be able to see better once you are outside the plane.

3. Not many people know this but on long-haul flights where passengers are served breakfast, lunch or dinner. The pilots are served different meals and cannot share, yes it's a rule. This is done to rule out the possibility of succumbing to food poisoning.

4. One of the most shocking revelation was that most large commercial planes can actually fly with one engine if need be.

5. The coffee that is served on the flight is absolutely disgusting. In case, you are wondering why, this is because the no one washes the container that goes out every morning. The station agents who needs to do this most of the time forget to it. Also, they don't have the proper supplies to clean it. So they pretty much just rinsed it out and dumped coffee. Also the drinking water used for coffee and tea is FILTHY. The holding tanks for the water have sometimes never cleaned.

6. The headphones that come wrapped up aren't new. The headsets are just cleaned packaged again.

7.There is a hidden latch on the lavatory door that will open the door when pulled, even when it's locked. Yes, you are can actually unlock airplane lavatories from the outside. Also there is usually a lock mechanism concealed behind the no smoking badge on the door. All you have to do is just to lift the flap up and slide the bolt to unlock.

8. It turns out the locks on suitcases are just useless. As you can easily pop a zipper with a pen and then drag the locked zipper the around the bag to close it back up.

9. Pilots are sleeping most of the time. Don't get shocked! But many pilots sleep while flying and most of the time they wake up to find their partner even asleep.

10. The reason why luggage gets left behind or 'lost' is that the bag is pulled for extra screening and doesn't make it to the plane on time. Or someone in the bag room made a mistake by sending the suitcase to the wrong plane.
