Transport Minister Darragh O'Brien says the 32 million passenger limit at Dublin Airport will be lifted in a sustainable way. The cap was introduced in 2007 as part of the planning conditions around the development of Terminal 2. Now the minister says he is bringing forward a memo to cabinet in the coming weeks to remove the cap. AdvertisementHe says, 'Dublin Airport is a big economic driver. If the cap is lifted, the number of passengers allowed to pass through the airport could reach up to 60 million.
