The airport operator has confirmed that the rules are changing following a multi-million euro investment in new screening technology. Thirty advanced C3 scanners, now installed in both terminals, can create 3D images of luggage contents, allowing security staff to inspect items without requiring them to be unpacked.

The new rules mean:

  • Liquids and gels can be carried in containers of up to two litres.


  • There is no restriction on the number of such containers.


  • Liquids and gels no longer need to be placed in separate plastic bags.


  • Electronics, including laptops, can remain inside carry-on bags.


What stays the same?
Passengers must still remove belts, heavy outerwear, and shoes that rise above the ankle for separate screening. All pockets must be emptied, and sharp objects longer than 6cm remain prohibited.

Items that cannot be brought through include:

  • Sharp objects such as knives, scissors (over 6cm), axes, or martial arts weapons.


  • Tools with blades or shafts longer than 6cm, including drills, saws, and chisels.


  • Stunning or incapacitating devices such as tasers, pepper spray, and tear gas.


  • Firearms, replicas, airguns, crossbows, harpoons, and slingshots.


Until midnight, the older rules still apply: liquids must be under 100ml, carried in a clear plastic bag, and removed from luggage for separate screening. Electronics and metallic items also need to be placed in trays, except when passing through a C3 scanner in Terminal 2.

According to Daa, Dublin Airport is one of the first major airports in Europe to fully implement this advanced technology, aiming to make security checks faster and less stressful for passengers.
