After the recent case of a passenger being forcibly removed from a United flight to make space for employees of the airline, the secret is out that airlines routinely overbook flights and are within their rights to bump you off yours. However, there are many other things airlines don’t tell you. Some of these can make your flying experience easier while others may make you want to stay on the ground and drive instead.

3. Overweight Baggage can be Dangerous
There’s a limit to what a plane may weigh for it to be able to take off and clear obstacles safely. The maximum take-off weight includes the weight of the fuel needed, the weight of the passengers and the weight of the baggage. The smaller the aircraft, the higher the risks posed by overweight baggage.

4. The Overhead Mask Doesn’t Contain That Much Oxygen
According to the Huffington Post, the cocktail of chemicals in the overhead mask will give you enough breathable oxygen for only about 15 minutes.

8. Dimming the Cabin Lights at Night is Not So You Can Sleep
The cabin lights are dimmed at night as a safety precaution rather than so you can sleep. The idea is that your eyes will adjust to the dark, so if the plane needs to be evacuated, you’ll be able to find your way out more easily.

13. There’s a Special Place for Rude People

14. Know Your Rights and the Airline’s Policies
According to Airfare Watchdog, if your flight gets substantially delayed, cancelled or rescheduled, the airline may be required to refund your ticket or allow you to reroute at no extra cost.
There are rules for tarmac delays in the United States too, but when airlines violate these rules, they get fined and you don’t get any compensation. You can read about Canadian passenger rights here.

15. Report Lost or Damaged Luggage Immediately
Travel Magazine says that if your luggage is lost, you need to report it immediately and file a Property Irregularity Form, or PIR, on the spot and send in a written claim for compensation within seven days.
The same goes for damaged luggage, such as when the airline breaks your guitar. If you wait too long to file the report and claim, your only option will be to write a song about it.

16. You’ll Want Sanitizing Wipes
The cabin is very, very dirty. Bring some sanitizing wipes, especially for the tray table, which often doubles as a diaper-changing table.

17. Don’t Fly Barefoot
It’s not only the tray tables, blankets and pillows that aren’t regularly cleaned. The carpets in the cabin get all kinds of nasty things spilled on them, so you’ll want to think twice about walking barefoot on them. Plus, in an emergency, you'll want to have your shoes on.

18. Your Pilot is Probably Exhausted
How Stuff Works explains that flight rules (in the US) only include the maximum amount of time a pilot may spend actually flying in a day, without taking into account the time spent on delays, pre-flight checks, baggage loading, boarding and fuelling. When your pilot has back-to-back flights, he or she may have been on duty for 14 hours or longer.

19. Economy Passengers Can Use the Business Line at Security
The special line for business class passengers at security is something that the airline has come up with. Airport security doesn’t actually care what kind of ticket you have, so if you’re flying in cattle class, there’s nothing stopping you from joining that much shorter line.

20. The Plane Can Fly With Only One Engine
Planes can fly with only one engine and the pilot probably won’t tell you if an engine has failed. Even more reassuringly, most planes can glide without any engines at all for long enough to get you safely back on the ground.
