"A spokeswoman for DAA last night said .... “We’ve been giving the clear bags out free of charge for 2.5 years, and we’re probably the only airport left in Europe still doing so,” she said. “Passengers don’t have to purchase the bags if they plan ahead.”"
Can that really be true? I know that Heathrow gives them away for free...
The purpose of the bag is just to group the toiletries together. The bag itself is not seen in the X-Ray. I just simply group the toiletries together and forget about the bag. This has never caused me any problems, in Ireland or anywhere else. Skip the bag and help the environment, and also save a couple of Euro in Dublin Airport.
