You are allowed to carry liquids in your carry-on luggage under the following conditions:
- Each liquid container must be no larger than 100 ml (3.4 oz).
- All liquid containers must fit into a single, transparent, resealable plastic bag with a maximum capacity of 1 litre (approximately 20 cm x 20 cm).
- You are allowed only one such bag per passenger.
- Liquids include drinks, gels, creams, pastes, aerosols, and similar substances.
- Liquids in containers larger than 100 ml must be placed in checked baggage.
- Exceptions are made for essential medicines, baby food, and dietary supplements, which may exceed 100 ml but require proof or separate screening.
- Liquids bought after security (e.g., duty-free) are allowed if sealed in a security bag with a receipt.
- Water bottles must be empty when passing through security but can be refilled afterward.
These rules apply broadly in the European Union, the UK, Canada, and the US, with minor local variations
. In summary, you can carry up to 1 litre of liquids in total in your carry- on, divided into containers of 100 ml or less, all fitting inside one clear resealable bag.
