For security reasons, liquids in hand luggage are restricted to containers of no more than 100 ml
each, with a total volume of 1 liter allowed in a resealable plastic bag. Any liquids exceeding this limit
must be placed in checked baggage. At the security checkpoint, any containers over 100 ml will be
confiscated and disposed of. Unopened, sealed containers are donated to various organizations. For
