Restrictions Apply
Special Rules Apply
According to CAA guidelines, at most UK airports, liquids in hand luggage must be in containers no larger than 100ml. The rule still applies if the container is partly full. Some airports may allow containers up to 2 litres, so check the airport before travel.
The final decision rests with the CAA officer on whether an item is allowed through the checkpoint. Official CAA Rules →
