Frankfurt Airport has moved to emphasise that it is business as usual despite last week's terror alerts.

The German airport said yesterday (17 August) that the ban on duty free liquids such as alcohol and cosmetics has been abolished, depending on airline regulations.

"As there are no restrictions for flights to other countries, passengers can continue to enjoy a shopping spree at Frankfurt Airport's Duty Free and Travel Value shops," the airport said.

The world's duty free trade has been holding its breath this week to see what regulations would be introduced on airlines after UK police claimed liquid bombs were being prepared to bring down planes over the Atlantic Ocean.

Although flight operations at Frankfurt Airport have been fully back to normal since the beginning of the week, London's airports have been thrown into disarray by the alleged plot, with long delays and thousands of passengers having their luggage misplaced.
