When it comes to travelling by air, there are a number of restrictions and guidelines that passengers must follow. One common question that arises is regarding the number of plastic bags that are permitted through airport security. The regulations can vary depending on the airport and the country, but generally, there are specific rules regarding the amount and volume of liquids that can be carried in hand luggage. Most airports enforce a limit on liquids, with containers typically restricted to a capacity of 100ml or less, and these must be presented separately in a single, transparent, resealable plastic bag.

Liquids must be under 100ml
Airport security regulations regarding liquids vary across different countries and airports. It is important to check with the specific airline and airport before travelling. Here are some general guidelines and instructions regarding liquids to keep in mind when passing through airport security:
Regulations for Containers and Bags
At most airports, you are not permitted to carry liquids in containers larger than 100ml through security, even if the container is not completely full. This restriction applies to liquids, gels, creams, pastes, and aerosols. These items must be in containers that are 3.4 ounces (100ml) or less per item. All liquid items must be placed in a separate, transparent, resealable plastic bag. The bag should hold no more than a litre and measure approximately 20cm by 20cm. The contents must fit comfortably inside the bag so that it can be sealed. Some airports may allow containers holding up to two litres of liquid.
Exemptions and Special Cases
Medicines, baby food and milk, and food for special dietary requirements are usually exempt from the liquid restrictions. Liquids purchased at duty-free shops at airports or on planes can be carried through security if they are sealed inside a security bag and have the receipt sealed and visible inside the bag. Duty-free liquids purchased internationally and transported on a connecting flight to the United States may be allowed in quantities larger than 3.4 ounces or 100ml if they are in a transparent, secure, tamper-evident bag and show no signs of tampering.
Screening and Additional Instructions
Airport security staff may need to open containers to screen liquids. Any liquid, gel, or aerosol that alarms during screening will require additional screening and may not be permitted in carry-on baggage. It is recommended to pack liquids, gels, and aerosols over 3.4 ounces or 100ml in checked baggage. Some airports have specific instructions, such as Heathrow's two-bag policy, where only two items of hand baggage are allowed through security control with specified size restrictions.
Other Considerations
It is important to note that airport security staff have the authority to prevent any item considered a security or safety risk from passing through, even if it is typically allowed. Additionally, some airports may have different requirements for electrical items and electronic devices, so it is advisable to check their power and inform the staff if they do not switch on when requested.

Only one plastic bag per person
When going through airport security, it is important to remember that you are limited to one plastic bag per person. This bag should be airtight, and the contents must fit comfortably inside so that it can be sealed without being knotted or tied at the top. The bag should be shown at the airport security point. Most airports require liquids to be in containers of no more than 100ml, and all liquids, gels, and aerosols that are over 3.4 oz or 100ml should be packed in checked baggage.
Some airports may allow you to take liquid containers that hold up to two litres of liquid. It is always best to check with the airport and your airline before travelling. For example, Heathrow Airport has a two-bag policy, allowing only two items of hand baggage with specific dimensions.
It is also important to note that medicines and baby food are usually exempt from the one-bag rule. Additionally, liquids purchased at duty-free shops can be carried in secure, tamper-evident bags, along with the receipt, without needing to be placed in the plastic bag with other liquids.
To avoid delays, it is recommended to pack all liquids, gels, and aerosols that are over 3.4 oz or 100ml in your checked baggage. Any liquid, aerosol, gel, cream, or paste that alarms during screening will require additional screening and may not be permitted in your carry-on bag.

Bag must be airtight, not knotted
When going through airport security, it is important to remember that you can only carry one plastic bag per person. This bag must be a clear, resealable plastic bag, such as a makeup bag or a freezer bag. The bag must be airtight and not knotted or tied at the top. It should hold a maximum of one litre and measure approximately 20 cm by 20 cm.
The contents of the bag must fit comfortably inside so that it can be sealed. This means that the bag must not be too full to close. Liquids, gels, and aerosols must be in containers that are no larger than 3.4 ounces (100 milliliters) per item. Any liquid, gel, or aerosol that is over 3.4 ounces or 100 milliliters should be packed in checked baggage, even if they are in a secure, tamper-evident bag.
Some exemptions apply to the rules regarding liquids. For example, you can take liquid containers larger than 100 milliliters through security at all UK airports if they are for essential medical purposes and are accompanied by a medical note or prescription. You can also take liquids purchased at the airport or on the plane, such as duty-free perfume, through security as long as they are sealed inside a security bag with the receipt.
It is important to note that airport security staff have the final say on what is allowed through, and it is always best to check with the specific airport and airline before travelling.

Contents must fit comfortably
When packing liquids, gels, and aerosols in your carry-on luggage, it is important to ensure that the containers are no larger than 3.4 ounces or 100ml. These items should be placed in a separate, transparent, resealable plastic bag. The bag should hold no more than a litre and measure approximately 20cm by 20cm.
It is crucial that the contents of the bag fit comfortably inside so that it can be sealed. This means that the bag should not be overfilled, and the items should not be overflowing or protruding from the bag. The bag must be airtight and should not be knotted or tied at the top.
If you are bringing multiple liquids, gels, or aerosols, they must all fit inside a single plastic bag. This means consolidating items and ensuring that the bag is large enough to accommodate them comfortably. It is important to note that some airports may allow you to carry liquid containers of up to 2 litres in your hand luggage, so it is always advisable to check the specific rules of the airport and airline before travelling.
Additionally, certain items are exempt from the liquid restrictions, such as medicines, baby food, and milk. These items can be carried in larger quantities and may not need to be placed in a separate plastic bag. However, it is still important to declare these items during security screening to avoid any issues.

Liquids bought at airport/duty-free
Generally, you are only allowed to bring a quart-sized bag of liquids, aerosols, gels, creams, and pastes in your carry-on luggage. These items must be in travel-sized containers that are 3.4 ounces (100ml) or less per item.
However, there are some exceptions for liquids bought at airport/duty-free shops:
- If you are travelling to the United States with a connecting flight, you may carry duty-free liquids in secure, tamper-evident bags that are more than 3.4 ounces or 100ml. The liquids must be packed in a transparent, secure, tamper-evident bag by the retailer and must not show signs of tampering when presented for screening.
- If you are travelling on a nonstop flight bound for the US, duty-free liquids purchased at an international airport will be permitted through the checkpoint if they meet US requirements for the use of tamper-evident bags.
- If you are travelling through Japan, be aware that they do not use or accept the ICAO tamper-evident duty-free bag. Therefore, it is recommended that you wait to purchase any liquid duty-free items until after you arrive in Japan.
- If you are travelling through Europe or another international destination, US duty-free liquid purchases in containers larger than three ounces will not be permitted through security checkpoints because they will not be in an ICAO-approved tamper-evident bag. However, some duty-free stores in US airports offer approved tamper-resistant bags, so make sure to ask the duty-free shop to place your items in this bag before you leave.
- If you are travelling with a baby, you are allowed to take enough baby food, baby milk, and sterilised water for the journey. You can also carry breast milk in your hand luggage even if you are not travelling with a baby.
Please note that countries outside the UK may have different rules regarding carrying liquids as a transit or transfer passenger. Always check with the airline(s) and airports before travelling.
