Airport security regulations regarding liquids can vary depending on the country and airport. In some cases, airports may provide plastic bags for liquids, but this is not always guaranteed. It is recommended to bring your own clear, resealable plastic bag to store liquids separately from your hand luggage. These bags should typically be no larger than 20cm by 20cm and hold no more than one litre. Each passenger is usually limited to one bag, containing containers of no more than 100ml. However, some airports have removed the requirement for liquids to be in a clear plastic bag, and certain items, such as lipstick, lip balm, and stick deodorant, may not be considered liquids at all. It's important to check the specific regulations of the airport and country you're travelling through to ensure compliance with their hand luggage restrictions.

What You'll Learn

Rules vary across airports
Rules regarding plastic bags for liquids vary across airports. While some airports provide plastic bags for liquids at security, others expect passengers to bring their own.
For example, some UK airports have removed the requirement for liquids to be in a clear plastic bag, meaning passengers can take as many liquids as they like without needing a plastic bag. However, at Manchester Airport, passengers are advised to prepare their liquid bag before arrival, though bags are available if forgotten. Gatwick Airport also provides plastic bags for liquids, though passengers are advised to put liquids in a disposable bag that can be thrown away if there is an issue.
Rules on what counts as a liquid also vary by airport, with some items, such as lipstick, not always being classed as a liquid. For example, while lipsticks are not classed as liquids at Manchester Airport, they are at Heathrow.
It is therefore important to check the rules of your departure airport before travelling.

Plastic bags are a security measure
Plastic bags are used as a security measure at airports to prevent the smuggling of illegal chemicals. Liquids must be stored in transparent, resealable plastic bags to allow security staff to easily examine the contents of hand luggage. This also helps to streamline the screening process by ensuring that all liquids are in one place, making it easier to interpret scans and images.
The use of plastic bags for liquids is a security measure that has been implemented by airports to enhance the safety of air travel. The bags are typically small and transparent, with a resealable opening, and are used to hold liquids, gels, and pastes. This measure was introduced to address concerns about the smuggling of illegal or dangerous substances onboard aircraft. By requiring liquids to be stored in these bags, security staff can easily view and inspect the contents of hand luggage, reducing the risk of prohibited items being brought onboard.
The use of plastic bags for liquids is just one of the many security measures that have been implemented at airports in recent years. Other measures may include body scanners, enhanced pat-downs, and restrictions on sharp objects or electronic devices. While some passengers may find these measures inconvenient, they are essential to ensure the safety and security of all travellers.
The specific rules regarding liquids and plastic bags can vary depending on the airport and the country. For example, some airports may require all liquids to be stored in a single plastic bag, while others may allow multiple bags. It is important for passengers to familiarise themselves with the specific rules and regulations of the airport and country they are travelling from to ensure compliance with security measures.
In some cases, airports may provide plastic bags for liquids if passengers forget to bring their own. However, it is generally recommended that passengers come prepared with their own bags to avoid any potential delays or inconveniences. By following the liquid restrictions and using the appropriate plastic bags, passengers can help ensure a smooth and efficient security screening process for themselves and others.

Liquids allowed without a bag
While most airports require liquids to be placed in a clear plastic bag, some have removed this requirement, allowing travellers to carry liquids without a bag. These airports include London City Airport, Schiphol Amsterdam, and Gatwick Airport.
At these airports, travellers can carry liquids in their hand luggage without placing them in a separate plastic bag. This change provides a more convenient and streamlined experience for passengers, eliminating the need to organise liquids into a designated bag.
However, it's important to note that the rules for liquids may still apply at these airports. Travellers are typically required to carry liquids in containers holding no more than 100ml or 3.4 ounces. These containers should be placed directly into carry-on baggage and must not be knotted or tied.
Additionally, certain items are exempt from the 100ml restriction. These include baby food, breast milk, prescription medicines, essential non-prescription medicines, and COVID-19 test kits. Passengers carrying these items are not required to use a plastic bag and can bring larger quantities.
It is always recommended to check the latest guidelines and regulations of the specific airport and airline before travelling to ensure compliance with their policies on liquids.

Bag requirements
The bag requirements for liquids depend on the airport and country. Some countries and airports have done away with the plastic liquids bag altogether. In the UK, the rules for taking liquids through security in hand luggage have changed at some airports.
For example, at Manchester Airport, passengers are permitted to take liquids, gels, and pastes through security separately from their hand baggage as long as they are in containers under 100ml and inside a transparent, resealable plastic bag. The bag must be no larger than 20cm x 20cm and not exceed one litre. Manchester Airport provides these bags if passengers forget to bring their own, though there is a limit of one liquid bag per passenger.
Similarly, Gatwick Airport requires liquids to be in a single, transparent, resealable plastic bag, which holds no more than a litre and measures approximately 20cm x 20cm. The contents must fit comfortably inside the bag so it can be sealed, and it must be airtight. Each passenger is limited to one plastic bag.
In contrast, London City Airport and Schiphol Amsterdam do not require liquids to be placed in a separate plastic bag.
When flying in the US, the TSA will not insist that liquids are in a plastic bag, whereas some other countries do. For instance, when flying from the EU to the US, passengers must undergo a US-style screening with all the familiar US domestic requirements.

Liquids in checked baggage
While the rules on what counts as a liquid can vary by airport, and some have done away with the clear plastic bags altogether, there are still some general guidelines to follow when packing liquids in checked baggage.
Firstly, it is important to research and take precautions to ensure that your liquids do not leak. This includes wrapping the tops of bottles or containers with tape to keep the cap secure. You can then place the container into a zipper-top plastic bag, seal it closed, and place that bag into a larger bag, pressing out all the air before sealing again. If the container is breakable, you can wrap it in bubble wrap or cloth, and then further protect it by wrapping it in a towel or clothing. Finally, place the wrapped bundle in the middle of your suitcase, surrounded by soft items and clothing.
Secondly, be aware that there are certain liquids that are prohibited in any amount, and their discovery during security checks can result in missed flights, arrest, or legal action. The Transportation Security Administration (TSA) has a list of prohibited liquids, including alcoholic beverages over 140 proof. IATA also has a list of hazardous materials that are not allowed. It is also important to consider your destination, as certain countries or states may have restrictions on importing certain liquids, such as alcohol in many Islamic countries.
Additionally, while you can generally bring larger liquids in your checked baggage, it is still recommended to use travel-sized containers whenever possible. This will help you avoid wasting product, and travel-sized bottles are also easier to pack securely.
Lastly, assume that your checked baggage will be inspected by a baggage security screener, so avoid packing valuables or prescription drugs in your checked baggage. Focus on packing only what you need, and consider using two-in-one products to save space.
