The operator of Dublin Airport has confirmed it won't appeal a decision blocking it from buying a giant carpark in Santry.
It says it could take years when parking spaces are urgently needed now.
Last week the Competition and Consumer Protection Commission refused daa permission to buy the former QuickPark facility over concerns it would lead to higher prices for consumers.
The car park, that is around a mile from the airport, has 6,200 parking spaces.
The airport operator says the appeals process could take years and that its passengers cannot wait that long.
It says there's an urgent need for spaces with all of its car parks fully sold out this easter weekend.
The daa is now urging the owners of the QuickPark site and any other potential bidders to act quickly to get the facility back open.
