You can bring liquids on a plane in containers that are 3.4 ounces (100 milliliters) or less per item when carried in your hand luggage. All these containers must fit inside a single transparent, resealable plastic bag with a maximum capacity of 1 liter (approximately 20cm x 20cm), and the bag must be presented separately at security screening
. Key points about liquids on planes:
- Each container must be 100 ml or smaller.
- All containers must fit comfortably in one clear, resealable 1-liter bag.
- You are generally allowed only one such bag per passenger.
- Larger containers of liquids should be packed in checked baggage.
- Some exemptions exist for duty-free liquids, essential medicines, baby food, and special dietary liquids, which may exceed 100 ml but must be declared and properly sealed
Some airports have started using advanced screening technology allowing passengers to keep liquids in their bags during screening, but the 100 ml size limit still applies
. In summary, the standard liquid size limit for carry-on luggage is 100 ml per container, all fitting within a 1-liter transparent bag, with some exceptions for medical and duty-free items
