DUBLIN AIRPORT HAS eased its old rules around liquids thanks to new scanning technology.

From midnight, passengers travelling through security in both Terminal 1 and Terminal 2 will no longer need to remove liquids, gels and electronics from their hand luggage. 

There is no limit on the number of liquids and gels that can be carried in hand luggage, and the old 100ml size limit on liquids and gels has been increased to two litres. 

Passengers will also no longer need to pack these liquids and gels inside clear plastic bags. 

The long-awaited rule change comes as a result of new ‘C3 scanners’. Using technology similar to CT scanners in hospitals, the machines generate 3D images of the luggage being scanned, which make it easier to detect what is inside.

Around 30 of the new scanners have been rolled out in Dublin Airport’s two terminals.

Despite the new technology, passengers will still need to take off items like belts, jackets, hoodies and shoes that extend over the ankle and put them in the security tray. They will also need to remove anything from their pockets. 

“This is a very positive and welcome development for passengers and staff. The new C3 scanners are best in class in terms of security detection standards and they significantly enhance the passenger experience,” Dublin Airport managing director Gary McLean said. 

Daa CEO Kenny Jacobs said Dublin Airport is “one of the first airports of its size in Europe to have this technology in place for every passenger”.

He said Cork Airport won’t be far behind, with work starting this month on construction of a new mezzanine floor that will extend over the existing Arrivals concourse and become home to a larger security area equipped with the latest C3 scanners.

“A safe and smooth security experience is a cornerstone of any airport’s passenger offering and that’s why we’re working so hard to make it great at Cork and Dublin airports,” Jacobs said. 

Daa said that while Dublin Airport is now fully C3 operational, other airports in the UK and Europe are not as advanced.

“Therefore, passengers booked to return to Dublin are encouraged to check the liquid rules at the airport from which they are flying back from,” the airport operator said.
