You can buy water on most flights but some people may want a particular brand (although water is water in my opinion) or perhaps may not want to pay airline prices.
You can take bottled water on a plane but you cannot take it through airport security – unless the bottle is smaller than 3.4oz/100ml or you have a baby with you, in which case the security regulations are more relaxed.
The airport security liquids rule is probably the most common rule that passengers fail to understand so end up having their liquids, including bottled water, confiscated by the security agent.
If you can’t take bottled water through airport security how can you take it on board?
Well there are a few options.
- You can buy bottled water in many airports after you pass through airport security. The departure lounge in many airports will generally have lots of stores to relieve you of your money while you wait for your flight and some will sell bottled water.
- You can take an empty water container through airport security and then fill it from a water fountain in the departure area, which many airports are now providing for passengers. In these days of reducing plastic use this is also a very green option.
But remember, the bottle must be empty! If it has any liquid in it, even if it is less than 100ml, then it is not allowed through airport security.
When can you take bottled water through airport security?
The TSA liquids rule applies to all passengers but is relaxed for parents who are traveling with a baby.
A parent may take sufficient bottled water with them for the baby during the flight, either to drink as water or to use to make up baby formula. The same applies to boiled, sterile water.
You can also take quantities of ready made formula or expressed breast milk over the 100ml liquids rule limit to feed the baby during the flight.
It is perhaps obvious but worth saying nevertheless that you must actually have the baby with you when you pass through airport security to be able to take the above with you.
See my article The TSA 3-1-1 liquids rule for full details of how you must carry liquids through airport security.
Can you take an empty stainless steel water bottle on a plane?
Yes, you can take any empty reusable liquids/water container on a plane and through airport security, whether it is made of stainless steel, aluminum, glass or plastic. But make sure they are actually empty otherwise they will be confiscated by the security agent.
You can buy many different types of reusable water bottles on Amazon Go on – save the planet!
Can you take bottled water in checked bags?
You can take bottled water in your checked bags but I cannot really see why you would as water is heavy so would use up your usually limited checked bag weight allowance.
Of course the exception may be if you are traveling to a country that has very poor sanitation and where sterile bottled water is not available. It may make sense to at least carry some in that case.
Is it good to drink water on a plane?
Air travel can certainly leave you dehydrated so drinking plenty of water while flying will help to reduce the possibility of this and make you feel less tired. Try not to drink alcohol, or at least keep it to a minimum as alcohol does dehydrate you.
Can you take cans of soda on a plane?
Yes you can take cans of soda, or any other type of drink, on a plane. Also these can be in bottles too. BUT you cannot take them through airport security with you (assuming they are not the tiny cans) so you will need to purchase them in the airport lounge to take on the plane with you.
And, no, they will not explode on a plane, either in your carry on or in your checked bags.
