What You'll Learn
Empty metal water bottles are allowed
If you're planning on bringing a water bottle onto a plane, rest assured that empty metal water bottles are allowed through airport security. This means that you can bring your empty reusable metal water bottle in your carry-on luggage. It is important to ensure that your bottle is completely empty before passing through security. You can dry it out by shaking out the last drops and then swinging your arm like a windmill in an outside area away from any people.
TSA regulations do not differentiate between metal and plastic water bottles, and both types must adhere to the same rules. The critical rule to understand is the 3-1-1 liquid rule, which limits the quantity of liquids, aerosols, pastes, or gels that can be taken through the airport security checkpoint by a single traveller. Specifically, you are only allowed to carry 3.4 ounces (100 mL) of liquid, which is not enough to stay hydrated on a long flight.
For this reason, it is recommended that you bring an empty water bottle and fill it up once you've passed through security. Water fountains are typically available post-security, so you can easily refill your bottle before boarding your flight. This way, you can stay hydrated during your journey without having to purchase single-use plastic water bottles.
By following these guidelines, you can confidently navigate airport security with your empty metal water bottle and enjoy a smooth and hassle-free experience.

3-1-1 liquid rule
You can carry a metal water bottle through airport security, but it must be empty when you pass through security. Water bottles, whether metal or plastic, are subject to the 3-1-1 liquids rule, which states that liquids must be in containers of 3.4 ounces (100 milliliters) or less. This rule was created by the Transportation Security Administration (TSA) in the USA to outline the restrictions for carrying liquids on board flights. It applies to all passengers travelling within and departing from the United States.
The 3-1-1 rule is a simple way to remember how to pack liquids in your carry-on luggage. The first '3' stands for 3.4 ounces, or 100 milliliters, which is the maximum size each liquid container can be. The '1' refers to the one quart-sized, transparent, resealable bag that these containers must fit into. Each passenger is allowed one such bag, which should be easy to open and close and kept separate from your carry-on luggage for inspection at security checkpoints.
While the 3-1-1 rule applies to most liquids, there are some exceptions. Medications, including prescription and over-the-counter medicines, are exempt from the 3-1-1 rule but must be declared to TSA officers at the checkpoint for inspection. Baby formula, breast milk, and juice for infants or toddlers are also exempt and do not need to fit within the quart-sized bag or adhere to the 3.4-ounce limit. Gel ice packs for cooling infant and child beverages are exempt as well, but they must remain frozen solid at the time of screening.
It is important to understand and follow the 3-1-1 rule to avoid delays and stress at the airport. By selecting travel-sized containers and properly sealing your liquids in a quart-sized bag, you can ensure a smooth and hassle-free security check.

Water fountains post-security
It is permissible to bring an empty water bottle through airport security. Many travellers opt to bring an empty water bottle in their carry-on luggage to refill at water fountains located post-security. This is because water fountains are typically available in this area.
Travellers have noted that some airports do not provide water fountains, including Istanbul Airport SAW, Paris Airport, Lombok, Kuala Lumpur, and Penang. In these cases, travellers are forced to purchase water at a significant markup, sometimes as high as 5000%.
To avoid this, some travellers suggest drying your water bottle completely before passing through security by shaking out the last drops and swinging your arm like a windmill in an outside area. Once through security, you can refill your bottle at a water fountain, if available, or from a tap or sink, though the water may taste unpleasant.
It is important to note that both metal and plastic water bottles must adhere to the 3.4 oz rule when passing through security.

Metal vs. plastic bottles
When it comes to travelling with a water bottle, it is important to note that the TSA does not differentiate between metal and plastic water bottles. Both must be empty and adhere to the 3.4 oz (100ml) rule for carry-on luggage. However, you can pack a full water bottle in your checked luggage. Many travellers prefer to bring an empty bottle in their carry-on bag and refill it at water fountains, which are typically available post-security.
Now, when it comes to choosing between a metal and a plastic water bottle, there are several factors to consider. Metal water bottles, typically made of stainless steel, offer several advantages. They are durable, corrosion-resistant, and do not leach chemicals when exposed to sunlight or heat. Metal bottles are also better for the environment, as they are 100% recyclable, reusable, and can save you money in the long run. Additionally, metal bottles have great insulation properties, keeping water cold for hours, and they do not retain flavours or odours. However, metal bottles tend to be heavier and more expensive upfront than plastic alternatives.
Plastic water bottles, on the other hand, are the most common type of bottle due to their low cost and lightweight design. However, they are more prone to cracks and deformation and chemical leaching. The recycling rate for plastic bottles tends to be low, and they can take nearly 700 years to decompose, contributing to the growing problem of plastic waste. Some consumers may also have concerns about the use of Bisphenol A (BPA), a chemical component found in some plastic bottles, although manufacturers are increasingly producing products free of this chemical.
Glass water bottles are another option, gaining popularity for their environmental benefits and aesthetically pleasing design. Glass bottles offer the best taste, do not leach chemicals, and are BPA-free. However, they are more prone to breaking and tend to be more expensive than plastic or metal alternatives.
Ultimately, the choice between a metal and plastic water bottle depends on your specific needs and preferences. Metal bottles are ideal for those seeking durability, insulation, and environmental friendliness, while plastic bottles may be preferred for their lightweight and low-cost characteristics. Glass bottles are also an option, offering the best taste but requiring careful handling.
