Perfumes, cosmetics or alcohol in their standard packaging can - as in the past - be purchased from the duty free and all other stores located behind the security checkpoints. There will be no problem transporting items purchased in the above mentioned stores when travelling especially inside the EU.
The sales personnel will package your purchase in a clear plastic, sealed bag. Please keep your sales slip which must have been issued on the day of your travel.
Changing flights inside the EU will not be a problem if you keep your bag with duty free items closed until you have reached your final destination. Special regulations apply for duty free items on aircraft departing to the USA. More specific information on this will be given by the stores.
