Passengers at Dublin Airport face a return to the old rules on carrying liquids in hand luggage from Sunday.

The change means passengers going through security will once again be limited to 100ml bottles – and will have to separate them out from the rest of their luggage.

Until recently, new scanners at Terminal 2 meant passengers were spared this hassle but a complaint from the European Union means a temporary return to the old rules. 

On Newstalk Breakfast, DAA spokesperson Graeme McQueen admitted it was “not great news for passengers.” 

“We got word a number of months ago that the EU was not happy with the way liquids were going through these new scanning machines that were being rolled out in airports all across Europe,” he said. 

“So, we’ve had to make a change to the way that liquids are going to be dealt with over the coming while - this is until a fix is found for a software issue with the new scanners. 

“So, for the next number of months - hopefully not too many - passengers are going to have to be prepared when they go through Dublin Airport to take their liquids out of their bags again. 

“All liquids, in both terminals, will need to be under 100mls.”

Mr McQueen said the return to the old rules will be “frustrating” but insisted it would not be a “long-term problem”. 

“The number one reason we’re putting [new scanners] in is that this is the best new technology from a safety and security point of view,” he said. 

“So look, this will be cleared up in a matter of months, we hope. 

“Once that is cleared up, the benefit of these scanners will be there. 

“This is a good investment for us… This will serve us for decades to come.”

In 2006, British authorities foiled terrorists who tried to take home-made chemicals in ordinary sport bottles onto a number of transatlantic flights.

Afterwards, restrictions on bringing liquids through security were introduced to prevent passengers taking potential explosive chemicals onto a plane with them.
