Perfume that is being carried in hand luggage should be packed in one-quart zip-lock plastic bags. The contents must fit comfortably in the bag. Empty containers and partially used larger containers are not permitted.
There is a limit of one plastic bag per passenger, permitted to be carried within hand luggage.
Duty-free perfume purchases will be sealed in a duty-free plastic bag to denote that it was purchased after the security checks.
