Common questions

Any pre-filled drink container over 100ml will be confiscated at the checkpoint without exception — this is one of the most consistently enforced liquid rules at airports worldwide. You will be asked to either drink it on the spot, pour it out, or leave it behind. An empty bottle, however, passes through with no issues and can be filled at a water fountain after the checkpoint.

Yes. The prohibition on pre-filled drink containers over 100ml in carry-on is consistent across all 14 regions we cover. There are no regional exceptions that allow you to bring a full water bottle through the security checkpoint. Beverages purchased from airside cafes or shops after you clear security are permitted on board on all carriers.

Screeners do not distinguish between water, juice, sports drinks, or any other beverage — all pre-filled liquids over 100ml are treated the same way and confiscated at the checkpoint. The type of liquid does not matter, only the container size. Coffee or tea in a takeaway cup purchased before security is subject to the same rule.

Bring an empty reusable water bottle through security and fill it at a water fountain or bottle-filling station after the checkpoint — most large airports have free water stations airside. Alternatively, buy bottled water from an airside shop after clearing security. Staying hydrated is especially important on long-haul flights, so filling up before boarding makes a real difference.
