Dublin Airport is set to scrap the 100ml liquid restriction for cabin baggage.

Authorities are currently testing new enhanced x-ray technology at the airport, which would mean passengers could bring whatever liquids they require without restriction on bottle size, as long as they are stored within cabin baggage.

Passenger security screening at Cork Airport is also set to be upgraded "next year", the DAA has said.

Similar machines are already being used at Shannon Airport.

A spokesperson for the DAA said: "As Dublin Airport has over 30 x-ray machines, across two terminals, this will be a complex process".

"The recent announcement of €6 million in Exchequer funding in Budget 2023 will be put towards the upgrading of the passenger security screening area at Cork Airport next year."

The project will involve the purchase of new state-of-the-art equipment, as well as the completion of works within the terminal building itself.

"When installed, the new technology at Dublin and Cork airports will end the need to remove laptops and liquids from cabin baggage and will enhance the overall customer experience for passengers," the spokesperson said.

The project at Dublin Airport is said to be in its very early stages, with tendering for construction work also being required.

This will ultimately determine the timetable for its rollout, a source said.

The DAA said it "continues to implement the EU-wide aviation security regulation in relation to the 100ml limit for liquids, lotions, gels and pastes at Dublin and Cork airports."

The liquids rule has been in place since 2006 to guard against terrorism.
