Airport liquid limits refer to the maximum quantity of liquids, gels, and aerosols that passengers can carry in their carry-on luggage when passing through airport security. These restrictions are in place for security reasons, aiming to prevent the transportation of hazardous materials that could threaten passengers and aircraft. The widely accepted liquid limit is 3.4 ounces or 100 milliliters per container, and these containers must fit into a single quart-sized, resealable plastic bag. However, it's important to note that some airports may have stricter rules, and certain items, such as baby formula, breast milk, and medications, are exempt from the airport security liquid limit. Understanding these liquid limits can save travelers time, prevent hassles, and ensure a smooth transition through security checkpoints.

What You'll Learn
Containers must be 3.4oz (100ml) or less
The 3.4oz (or 100ml) liquid limit at airports is a security measure to prevent the transportation of hazardous materials that could threaten passengers and aircraft. These restrictions apply to liquids, gels, creams, pastes, and aerosols. This rule is widely accepted by airports worldwide, but some airports may have stricter rules, so it's important to check the regulations of your specific airport before travelling.
Containers holding liquids, gels, or creams must be 3.4oz (100ml) or less to be allowed through airport security in your carry-on luggage. These containers must be placed into a single, quart-sized, clear, resealable plastic bag with a capacity of no more than 1 litre. Each passenger is allowed one such bag. This facilitates the screening process and allows security personnel to easily view the items.
It is recommended to use travel-sized containers for your liquids, gels, and creams to ensure they meet the 3.4oz limit. Many reputable brands offer mini versions of their products, making it convenient to maintain your grooming routine while travelling. Alternatively, you can transfer your products into smaller, travel-friendly containers.
Some items are exempt from the 3.4oz limit, including baby formula, breast milk, medications, and baby food/drink for infants under two years old. These exempt items do not need to be placed in a plastic bag, but they must be declared to the screening officer for inspection. Additionally, duty-free liquids purchased internationally and transported in a secure, tamper-evident bag with a receipt may be allowed through security in some cases.

All liquids must fit in a 1L plastic bag
To ensure a smooth transition through airport security, it is essential to understand the liquid limit regulations. These restrictions are in place for security reasons, aiming to prevent the transportation of hazardous materials that could threaten passengers and the aircraft. While the specific rules may vary slightly depending on the airport and country, the standard limit for liquids carried in hand luggage is 3.4 ounces (100 milliliters) per container.
To comply with these regulations, it is recommended to use a quart-sized or litre-sized, resealable plastic bag to store your liquid items. This includes any liquids, gels, creams, pastes, or aerosols. All liquid containers must fit comfortably inside this bag, which should then be placed in a bin at the screening point. The bag ensures that the liquids are readily visible to security personnel, reducing potential delays.
Some items, such as baby formula, breast milk, medications, and canned goods containing less than 100 ml of liquid, are exempt from the quantity limit. However, they must still be packed in the same clear, resealable 1-litre plastic bag. It is important to note that any liquid, regardless of its volume, that alarms during screening will require additional screening and may not be permitted in your carry-on baggage.
For duty-free liquids, there are specific conditions under which they are allowed in carry-on baggage. These liquids must be purchased internationally, packed in a secure, tamper-evident bag by the retailer, and not show any signs of tampering when presented for screening. Additionally, the original receipt must be presented, and the purchase should have been made within 48 hours.
To avoid any issues, it is advisable to pack strategically. Use travel-sized containers or transfer your products into smaller, travel-friendly bottles. Check the regulations of your departure and arrival airports, as some may have stricter rules. Staying informed and adhering to the liquid limits will contribute to a seamless travel experience.

Screening: CT scanners reduce false alarms
Airport security liquid limits refer to the maximum quantity of liquids, gels, and aerosols that passengers can carry in their carry-on luggage. The standard limit is 3.4 ounces (100 milliliters) per container, and these containers must fit into a single quart-sized, resealable plastic bag. These restrictions are in place for security reasons, aiming to prevent the transportation of hazardous materials that could threaten passengers and aircraft.
However, traditional X-ray machines used at airport security checkpoints can sometimes produce false alarms when screening liquids and gels, leading to additional checks and delays for travellers. This is where CT scanners come in as an upgraded security measure.
CT (Computer Tomography) scanners create clear, 3D images of baggage contents, enabling security operators to inspect bags from every angle. With advanced image resolution and AI-driven algorithms, these scanners can automatically detect weapons, explosives, and other prohibited items with greater accuracy. This technology minimizes false alarms, making the security screening process more efficient and less stressful for passengers.
Numerous major airports, such as Los Angeles' LAX and New York's JFK, have been using CT scanners for several years. The Transportation Security Administration (TSA) in the United States has been deploying this technology across the country since 2021, with plans to extend it to smaller airports. Similarly, the European Union has mandated the implementation of CT scanners at airports by 2026.
While CT scanners offer improved security and efficiency, they have also faced some challenges during their initial rollout. One issue is the smaller entry tunnel size compared to traditional X-ray machines, which means not all larger carry-on bags will fit. This has resulted in longer lines and increased wait times as passengers adjust to the new process. However, as passengers and staff become more familiar with the technology, these delays are expected to ease over time.

Exemptions: Baby formula, breast milk, medication
The Transportation Security Administration (TSA) has strict rules about liquids, gels, and aerosols that can be carried onto an aeroplane. Liquids are limited to travel-sized containers of 3.4 ounces (100ml) or less. However, there are exemptions for baby formula, breast milk, and medication.
Baby formula, breast milk, toddler drinks, and baby/toddler food (including puree pouches) are allowed in quantities greater than 3.4 ounces or 100ml. They do not need to fit within a quart-sized bag. This also applies to cooling accessories, such as ice packs, freezer packs, and gel packs, even if there is no baby or toddler travelling with you. It is recommended that these liquids be transported in clear, translucent bottles, as bottles can be scanned, whereas plastic bags or pouches may need to be opened for alternate screening.
Additional screening procedures will be required to clear these items, including Advanced Imaging Technology screening and additional screening of other carry-on property. TSA officers may need to test the liquids for explosives or prohibited items. If you do not want the baby formula, breast milk, or related items to be X-rayed or opened, inform the TSA officer.
Medically necessary liquids, gels, and aerosols are also allowed in reasonable quantities, but they must be declared to TSA officers at the checkpoint for inspection.

Rules vary by airport and country
The rules for liquid limits at airports do vary by airport and country. While the 3.4-ounce (or 100ml) limit is widely accepted, some airports and countries have different regulations and technology in place, which affects the liquid limit. It's important to check the rules for your specific departure and arrival airports before travelling.
Some countries, such as the UK, have a standard liquid limit rule across all their airports. In the UK, the liquid limit is 100ml, with a total of 1 litre per passenger. However, even within the UK, there are variations in the rules at different airports. For example, at London City Airport, passengers can keep liquids in their hand luggage without needing to remove them, whereas at Manchester Airport, passengers are advised to pack liquids in their hold baggage.
Other countries, like the United States, have a standard liquid limit across the country, but the rules may vary depending on the airport or even the specific terminal. For example, Los Angeles International Airport (LAX) and New York's JFK International Airport have had CT scanners for several years, while smaller airports may still be using traditional X-ray machines, which have different liquid restrictions.
Additionally, some countries or airports may have stricter rules than others. For example, while the European Union has a 100ml liquid limit regulation, some countries and airports within the EU have chosen to operate under local laws, resulting in different liquid limits. Groupe ADP, which operates three airports in the Paris region, began testing new explosives detection equipment in October 2022, allowing passengers to carry liquids in 100ml containers in their hand luggage. Similarly, Rome–Fiumicino International Airport's Terminal 1 also permits passengers to keep liquids in their cabin bags without removing them during security checks.
The varying rules and restrictions on liquid limits at airports and countries can be challenging for travellers, especially those with layovers or transfers in multiple destinations. It is always recommended to check the latest regulations and restrictions before travelling to ensure a smooth and hassle-free journey.
