What You'll Learn

Frozen liquids are allowed if frozen solid at screening
Frozen liquids are permitted through airport security as long as they are completely frozen when presented for screening. This means that if your frozen liquid has partially melted and is slushy, or has any liquid at the bottom of the container, it will not be allowed through and must adhere to the standard liquid requirements.
It is worth noting that keeping liquids frozen throughout your journey to the airport, during the wait in line, and until you go through screening can be challenging. To increase your chances of getting frozen liquids through security, it is recommended to use a quality insulated container. Additionally, consider bringing an empty 100 ml bottle to pour any melted liquid into before screening.
While frozen liquids are generally allowed if frozen solid, there have been reports of inconsistencies across different airports and countries. For example, in the UK, some travelers have had their frozen liquids confiscated, while others have been allowed to pass through with frozen liquids. Similar variations in enforcement have been observed in the US, with some travelers suggesting that bringing frozen liquids may depend on the discretion of individual TSA officers.
To avoid any issues, it is advisable to check the specific regulations of the airport and country you are traveling through. Additionally, planning ahead and properly packing your items can help facilitate the screening process and make your travel experience smoother.

Partially melted frozen liquids must meet 3-1-1 liquid requirements
Frozen liquids are generally allowed through airport security as long as they are completely frozen when presented for screening. However, if a frozen liquid item has partially melted and has any liquid at the bottom of its container, it is then subject to the same rules as regular liquids and must comply with the 3-1-1 liquids requirement. This means that the liquid must be in a container that is no larger than 3.4 ounces or 100 ml, and all such containers must fit inside a single 1-quart plastic bag. Each passenger is limited to one such bag, which they must remove from their carry-on and place in a separate bin for screening.
The 3-1-1 rule was implemented by the Transportation Security Administration (TSA) in the United States to enhance security and facilitate the screening process for carry-on luggage. It helps TSA officers quickly and efficiently screen liquids for potential security threats while allowing passengers to bring small quantities of liquids onboard.
It is important to note that even if an item is generally permitted, it may still be subject to additional screening or prohibited from passing through the checkpoint if it triggers an alarm, appears tampered with, or raises other security concerns. The final decision regarding what items are allowed rests with the TSA officer at the checkpoint.
To avoid any issues, it is recommended to plan ahead and properly pack any frozen liquid items. Additionally, passengers can consider alternative options, such as purchasing beverages or food items containing liquids after passing through security or once onboard the aircraft.
By understanding and adhering to the 3-1-1 liquids requirement, passengers can ensure a smoother travel experience and contribute to maintaining a safe and secure airport environment.

Frozen liquids can be used to keep medication cold
When travelling with medication that needs to be kept cold, it is important to plan ahead. Frozen liquids are allowed through airport security as long as they are frozen solid when presented for screening. This means that you can use frozen liquids to keep your medication cold during your journey.
One option is to use a cooler bag or a small lunch bag to insulate your medication with ice. You can purchase ice from vendors at the airport, or bring your own frozen ice packs, as long as they are completely frozen during security screening. Alternatively, you can ask for a cup of ice at shops or gas stations when you reach your destination. Simply pour the ice into a resealable bag and place it in your bag with your medication.
If you are travelling with breast milk, it is permitted to bring frozen milk for toddlers under the age of two through security. It is important to note that if your frozen liquids have partially melted and there is liquid at the bottom of the container, it must meet the standard liquid requirements for travel.
Some hotels offer a small refrigerator in your room, which can be used to store your medication. If you are unsure, you can contact the hotel ahead of time to make arrangements for storing your medication properly.

Dry ice in an airtight container is not permitted
Frozen liquid items are permitted through airport security as long as they are completely frozen when presented for screening. However, specific rules and restrictions apply to dry ice. Dry ice, the solid form of carbon dioxide, is permitted in carry-on baggage and checked baggage but only in limited quantities and under specific packaging and labelling requirements.
Firstly, the quantity of dry ice per package and per passenger is restricted to 2.5 kg (5.5 lbs). This limit is set by the Federal Aviation Administration (FAA) and applies to all passengers. It is important to note that airline approval is required for carrying dry ice, and passengers should contact their airline beforehand to obtain the necessary approval.
Secondly, dry ice must be properly packaged and marked. The package must not be airtight and must allow for venting and the release of carbon dioxide gas. When packed in checked baggage, the package must be clearly marked with the label "Dry ice" or "Carbon dioxide, solid", along with an indication of the net quantity of dry ice or a mention that it is within the permitted limit of 2.5 kg (5.5 lbs).
It is worth noting that additional non-hazardous ice packs, such as blue ice or gel packs, can be used alongside dry ice to supplement cooling. However, if the item contains any liquid or gel exceeding 100 ml (3.4 oz) per container, TSA security rules mandate that the product must be entirely frozen solid when passing through security screening.
In summary, while frozen liquids are generally allowed, dry ice in an airtight container is not permitted due to safety considerations. Passengers wishing to travel with dry ice must adhere to the specified quantity limits, packaging requirements, and labelling standards to ensure compliance with airport security regulations.

Rules vary depending on the country and airport
The rules regarding taking frozen liquids through airport security vary depending on the country and airport. In the United States, frozen liquid items are generally allowed through Transportation Security Administration (TSA) checkpoints as long as they are frozen solid when presented for screening. However, if the frozen liquid item has partially melted and has any liquid at the bottom of the container, it must meet the standard liquid requirements for carry-on luggage, typically needing to be in containers of 3.4 ounces (100 ml) or less. It is worth noting that individual TSA officers have the final say on whether an item is allowed through the checkpoint, and items may be subject to additional screening or prohibited if they trigger an alarm, appear tampered with, or raise other security concerns.
In the United Kingdom, there are conflicting reports of airport security confiscating frozen liquids. Some travellers have reported that UK airport security considers frozen liquids as non-compliant with liquid restrictions, classifying them as non-solids. However, other travellers have successfully brought frozen liquids through UK airports, particularly when used to keep medication or breast milk cold during travel.
Similar inconsistencies exist in other countries. For example, a traveller reported that their bottle of frozen water was confiscated at an airport in Chile, while another traveller mentioned that their nearly melted bag of ice was allowed through security in Melbourne, Florida.
To avoid any issues, it is recommended to check with the specific airport and country regulations before attempting to bring frozen liquids through airport security. Each country and airport may have unique rules and guidelines, and staying informed can help ensure a smooth travel experience.
