High-Tech Scanners to Ease Air Travel Restrictions on Liquids

Advanced tomography scanners are poised to eliminate the long-standing rule restricting the transport of liquids to 100 ml in carry-on luggage, streamlining security checks and reducing wait times.

Since 2006, passengers have been limited to carrying liquids in their hand luggage in containers of no more than 100 ml. Now, after 18 years, several countries are set to abolish the 100 ml liquid rule thanks to new and improved security scanners. Utilizing tomography technology, akin to that used in medicine, these scanners can provide clear 3D images of the contents of passengers’ bags.

Some European airports have already lifted the 100 ml threshold. The new scanners are currently in operation at the Teesside International Airport in the UK, as well as at Schiphol in Amsterdam, Helsinki Airport, Munich Airport, Leonardo da Vinci International Airport in Rome.

Aena is going to install new X-ray technology scanners at passenger control points that generate a three-dimensional image in the first half of 2024. In 2024, passengers at Copenhagen Airport also will be able to leave electronic devices and liquids in their bags during screening. Belts, watches, and shoes will also no longer have to be removed.

After the installation of these scanners, the 100 ml rule will be gradually phased out over the next two years. Passengers may not immediately perceive the benefits of this new technology, but it promises to significantly enhance the efficiency of security procedures and contribute to a smoother travel experience.
