Throughout the years, air travel has changed dramatically. After 9/11 there were many things that were changed in order to keep the passengers safe. Here are 3 crazy things you used to be able to do on an airplane.

Carry Knives

Security wasn’t nearly as strict decades ago and you used to be able to carry a knife with you on a plane. Round butter knives and plastic knives are still allowed but since 2001 anything else that could be considered a weapon is prohibited. However, you can still check nearly any kind of knife in your checked luggage including Swiss army knives, swords, or anything with a blade. The only blade that is illegal to transport in many states are butterfly knives. This is one of those airplane prohibitions that make sense.



Another thing that used to be allowed on airplanes is smoking. Even though smoking was once allowed on airplanes, it was banned in the 1990s. E-cigarettes were also banned in 2015. While it is a well-known fact that smoking can cause health problems, almost half a million people in the U.S. still die due to smoking-related illnesses every year. Smoking has been known to cause cancer, heart disease, strokes, lung diseases, diabetes, and many others. Second-hand smoking can also cause many of the same diseases. If you smoke on a plane today you’ll at least face a fine and at most be arrested or detained upon landing.


Bring Liquids

Before 2001, you used to be able to bring liquids on the plane with you. Now, anything larger than a 3.4 liquid ounce bottle needs to be checked. This includes things like toothpaste, sunscreen, shampoo, mouthwash, lotion, and water. If you want a bottle of water for your flight, you have to fill it up at a fountain or buy one inside the airport. Liquids were banned from planes because many believe that liquid chemicals can be used in an attack. Filling up a water bottle may be annoying, but when it’s a matter of safety, it’s not a big deal.


These are just 3 crazy things that you used to be able to do on an airplane, but there are many others. All these things might not make sense to be prohibited, but preventing another 9/11 type attack makes it all worth it.
