Why Is Water Not Allowed On Planes?

We’ve all been there. You’re at the airport, about to board your flight, and you’re thirsty. You go to take a swig from your water bottle, only to be stopped by a flight attendant and told that you can’t bring it on the plane. But why is that? Why is water not allowed on planes?

Turns out, the liquid ban was introduced around the world after a transatlantic terrorist plot was foiled in August 2006, in which a group planned to detonate liquid explosives on board multiple flights. While this may seem like a silly reason to ban water bottles, it’s actually a pretty smart move when you think about it. After all, what’s more likely to explode on a plane: a bottle of water or a can of soda?

So, why is water not allowed on planes?

There are a few reasons why water is not allowed on planes. The first reason is that it can be used as a weapon. A person could easily splash water in someone’s face to cause distraction or disorientation. Additionally, water can be used to short circuit electronic equipment. Another reason is that water can leak and cause damage to the plane. Even a small amount of water can cause mold and mildew to grow, which can damage the plane’s interior. Finally, water is a limited resource on a plane and it is important to conserve it for emergency situations.

Let’s dig into it and see if we can find a solution.


  • The best way to stay hydrated during a long flight is to drink plenty of water and use a hydration supplement like chia seeds. Avoid diuretic drinks like caffeine and alcohol, and pack some eye drops to help keep your eyes moist.
  • Bringing water onto a plane can cause serious safety hazards, including increasing the risk of fire, short-circuiting electrical equipment, causing corrosion, and freezing and blocking pipes. It is important to follow the rules and not bring any water onto a plane in order to keep everyone safe.
  • The benefits of not bringing water on a plane include reducing the risk of dangerous liquids onboard, saving fuel and money, and preventing the spread of diseases.
  • The best way to stay hydrated when you’re not allowed to bring water on a plane is to drink plenty of water before your flight and to bring along some snacks that are high in water content. You should also drink other beverages besides water, and use a humidifier in your hotel room. Drinking plenty of water as soon as you land will also help to rehydrate your body after the flight.
  • Other alternatives to bringing water on a plane include bringing juice or liquid nutrition, and packing any necessary medications.

Can You Take Water On A Plane?

Yes, you can bring a reusable water bottle with you through airport security. However, you will not be able to fill it up until after you have gone through the security screening process. Once you are through security, you can fill up your water bottle at one of the many water fountains located throughout the airport.

Can Airlines Deny You Water?

No, airlines cannot deny you water. According to the 2011 Aircraft Drinking Water Rule (ADWR), US airlines are required to provide passengers and crew with safe drinking water. This means that if you ask for water on a flight, the airline must provide it to you. There may be some exceptions to this rule, such as if the airline is unable to provide water due to a mechanical issue, but in general, you should be able to get water on a flight if you request it.

Can You Bring Unopened Water On A Plane?

You are allowed to bring an empty water bottle through airport security. You are also allowed to bring a full water bottle in your checked baggage. However, you cannot bring a water bottle that exceeds 3.4 ounces through the checkpoint.

Can You Bring Unopened Water Through Tsa?

The TSA allows travelers to bring an unopened water bottle through airport security, as long as it is empty. Water for babies is allowed in reasonable quantities in carry-on bags. All other liquids, gels, and aerosols must follow the TSA’s 3-1-1 rule, meaning they need to be in 3.4-ounce containers (or smaller) and then placed in one clear, quart-sized bag. Frozen liquids are allowed through the checkpoint as long as they are frozen solid when presented for screening.

When Did Liquids Get Banned On Planes?



  • Can You Bring Water On A Plane During Covid?: You can bring water on a plane during covid, but there are some things to keep in mind. All liquids, gels, and consols must be in containers that are 3.4 ounces (100 milliliters) or less per item and placed in a clear, quart-sized bag. Only one item per bag is allowed. Many airlines are not offering food or drink services, so you will need to make sure you have enough for the entire flight. Experts still recommend taking some precautions when travelling during the pandemic, such as wearing a mask and carrying hand sanitizer. When you get off the plane, you will want to take some steps to ensure you are just as healthy as when you boarded, such as washing your hands and avoiding touching your face.
  • Can We Carry Water Bottles In International Flights?: You can bring an empty water bottle through TSA security at the airport and fill it up after you pass through security.
  • Are Liquids Still Banned On Airplanes?: The TSA’s 3-1-1 rule for liquids is still in effect.

Final Word

Now, you might be wondering why water is included in this ban. After all, what harm could a little H2O do? Well, it turns out that water can be pretty dangerous at 30,000 feet.

First of all, water is a conductor of electricity, which means it could potentially cause a short circuit and take out some important systems on the plane. Additionally, water can freeze at high altitudes, which could block vital air vents and cause the plane to lose altitude. And finally, if a bottle of water were to leak, it could slip through cracks and crevices in the plane and cause serious corrosion.

So, next time you’re packing for a flight, leave the water bottle at home. Your fellow passengers will thank you!
