You can take liquids in your carry-on luggage on a flight under the following rules for 2025:
- Liquids must be in containers of 100 ml (3.4 ounces) or less.
- All these containers must fit into a single transparent, resealable plastic bag with a total capacity of no more than 1 liter (about one quart).
- Each traveler is allowed only one such quart-sized liquids bag. If you have more liquids, they must go into checked baggage or be distributed among other travelers' bags if possible
There are important exceptions to these rules:
- Prescription medications, including liquids, creams, and pre-filled pens or syringes, are allowed in larger quantities if kept in their original labeled containers. Over-the-counter medications and medical gels/creams are also permitted in larger amounts
- Infant and child nourishment such as breast milk, baby formula, and juice boxes can be carried in quantities over 100 ml and do not need to be in the liquids bag
- Liquids purchased at duty-free shops or on the plane can exceed the 100 ml limit if they remain sealed in the security tamper-evident bag with the receipt inside
- Some airports equipped with advanced 3D CT scanners (e.g., Gatwick, Birmingham, Newcastle) allow you to keep liquids in your bag during security screening, but the 100 ml container size limit still applies
For checked baggage, liquid restrictions are much less strict, and you can generally carry larger quantities, but it is advisable to check specific airline policies. In summary, for carry-on luggage, you can carry liquids up to 100 ml per container, all fitting into one 1-liter transparent bag, with exceptions for medications, baby food, and duty-free liquids. Larger quantities must be checked in or qualify for exemptions. This is the current standard for most airports in the US, UK, EU, and many other regions in 2025
