You can bring one shopping bag of goods bought in the duty-free shops onto the aircraft. It is vital that the products are placed in a bag by staff working in the duty-free shops. Products bought in the stores are sold in specially sealed, transparent plastic bags. Shop employees will place the receipt or receipts for the sold goods into the bag so that the details (purchase date and location) can be read from the outside without opening the bag. The transparent shopping bags will be sealed by staff in the shop and should under no circumstances be opened by the passenger until the final destination of their flight.
