Airport security rules vary depending on the country and airport, so it's always best to check with the specific airport before travelling. In general, liquids are allowed through security as long as they don't exceed a certain volume, usually 3.4 oz or 100ml. This rule applies to water, so you can bring a bottle through security as long as it complies with the volume limit. Some airports allow liquids of up to 2 litres, but this may vary. It's recommended to bring an empty refillable bottle and fill it up after passing through security.
| Characteristics | Values |
|---|---|
| Containers | Multiple containers are allowed as long as they are up to 2 litres. |
| Container type | Containers can be metallic or double-walled, but they must be empty before the security checkpoint. |
| Liquids | Liquids, gels, and spreadable foods must be less than 3.4 oz. |
| Food | Solid foods are usually allowed. |
| Food storage location | Food can be packed in hand luggage, but it is recommended to pack it in hold luggage to avoid hold-ups during security checks. |

What You'll Learn
Liquids under 3.4 oz/100ml are allowed
It's worth noting that this rule applies to all liquids, gels, and spreadable foods. So, if you're travelling with other liquids, like salad dressing or shampoo, they also need to be in containers that are 3.4 oz/100ml or smaller. These containers should be placed in a clear, plastic bag for ease of inspection.
Additionally, it's important to be aware that even if an item is generally permitted, it may still be subject to additional screening or may not be allowed through if it triggers security concerns. This decision rests with the TSA officer at the checkpoint.
While the 3.4 oz/100ml rule is a standard guideline, it's always a good idea to check with the specific airport and airline you're travelling through and with, as regulations can vary. For example, Edinburgh Airport currently allows liquids of up to 2 litres through security, but metallic or double-walled containers must be empty before passing through the checkpoint.

Empty, refillable bottles only
If you're travelling with a refillable water bottle, it's important to know the restrictions that apply. While it's convenient to have your own bottle, you'll need to follow a few simple guidelines to ensure you're able to bring it with you through airport security.
Firstly, it's important to note that the rules may vary depending on the airport and the country you're travelling from or to. For example, in the UK, there are restrictions on the amount of liquid you can take in your hand luggage. Similarly, in the US, the Transportation Security Administration (TSA) has specific guidelines for liquids. It's always a good idea to check with the specific airport and country regulations before your travel.
To avoid any issues, it's best to bring an empty, refillable water bottle with you. This is because most airports have restrictions on the amount of liquid allowed through security, often limited to small containers of 3.4 ounces or 100 millilitres. These restrictions apply to water and other liquids, gels, and spreadable foods. Even if your bottle is partially filled, it may be subject to additional screening or not allowed through the checkpoint.
By bringing an empty bottle, you can easily refill it after passing through security. Many airports provide water fountains or dispensers specifically for this purpose. This ensures you stay hydrated during your flight without having to purchase water after security, which can be expensive.
In addition to the liquid restrictions, it's important to consider the type of bottle you're bringing. If you're travelling with a metallic or double-walled container, such as a vacuum flask or a thermos, it's essential to ensure it's empty before reaching the security checkpoint. These types of containers may need additional screening, so saving yourself any potential delays is beneficial.
In summary, when travelling through airport security, it's best to bring an empty, refillable water bottle. This allows you to comply with liquid restrictions and refill your bottle once you're through security. Checking specific airport and country regulations is always recommended, but by following this simple guideline, you can ensure a smooth journey and maintain your hydration needs during your flight.

No frozen liquids
While there are some conflicting views on taking liquids through airport security, one thing is clear: frozen liquids are a no-go. Even if the liquid is frozen solid, it will not be allowed to pass through security in your carry-on luggage. This rule applies to food items too, so no ice cream or frozen yoghurt either!
The reason for this is that frozen liquids can be a security risk. If a liquid is frozen, it can be difficult to identify and, as one source points out, there's no way to know that it's a bottle of water inside the ice rather than something more sinister.
Some travellers have tried to take frozen liquids through security, and occasionally, they have been allowed to do so. However, this is not worth the risk, as you may be asked to discard the item. One traveller commented that they "decided to leave it at that point" after a TSA official told them that "the government does not classify that as a solid".
It is best to avoid any disappointment or delay by not packing frozen liquids in your carry-on luggage. If you are unsure about an item, it is always best to check with the airport or airline before you travel.
Overall, while it may be tempting to try and beat the system by freezing your liquids, it's just not worth the potential hassle and stress. It's better to stick to the rules and avoid any frozen liquids in your carry-on luggage.

Solid foods are fine
You can bring solid food items through airport security. However, there are some guidelines and restrictions to be aware of. Solid foods such as sandwiches, fruit, pizza, salads, snacks, and candy can go through airport security. If you have special dietary requirements, such as a gluten-free or vegan diet, you may bring your own food, but it must go through the X-ray machine for screening.
Food items in aluminum foil or containing metal may trigger the metal detector and require additional screening. It is recommended to avoid wrapping food in foil, as it may be confiscated by TSA agents. Food and powders can block images on the X-ray machine or be mistaken for suspicious items, so it is best to pack them in checked luggage if possible. If not, allow extra time for additional security checks.
Solid foods that could melt at higher temperatures may not be allowed through security. For example, coconut oil is a solid at 76°F (24°C) but becomes a liquid at 77°F (25°C). Therefore, it is important to consider the temperature inside the airport when bringing solid foods that could melt.
Additionally, while solid foods are generally allowed, any liquids or gels must follow the 3-1-1 rule. This means you can bring containers holding 3.4 ounces (100ml) or less of liquid or gel, inside a clear, quart-size bag. This includes items such as sauces, dips, and salad dressings.
Finally, even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm during screening, appears tampered with, or poses security concerns. The final decision rests with the TSA officer regarding what items are allowed through the checkpoint.

Different rules for US flights
Each airport may have different rules and equipment, so it is always best to check with the specific airport and airline you are travelling with. However, there are some general rules regarding taking water through airport security.
For US flights, the TSA guidelines state that you cannot take a full water bottle through security checkpoints. This is due to the 3.4 oz (100ml) rule for liquids, gels and aerosols in carry-on bags. Therefore, if you are bringing a water bottle onto a plane, it must be empty when you pass through security. You can then fill it up for free after security. This rule applies to all types of water bottles, including stainless steel, plastic, and insulated bottles. Insulated bottles are a good option as they prevent leaks and can keep your water cold for a long time.
It is worth noting that some airports may have different rules. For example, Edinburgh Airport allows liquids of up to 2 litres through security, as long as they are in multiple containers. However, metallic or double-walled containers (including vacuum flasks, thermos flasks and metallic water bottles) must be empty before passing through the security checkpoint. Additionally, all gels, pastes, lotions, liquid-solid mixtures (including food) and pressurised containers are considered liquids. Frozen liquids and foodstuffs are not permitted in cabin baggage.
It is important to plan ahead and pack properly to facilitate the screening process and ease your travel experience. Even if an item is generally permitted, it may be subject to additional screening or not allowed through if it triggers an alarm, appears tampered with, or poses security concerns. The final decision rests with the TSA officer.
