The Dublin Airport (Passenger Capacity) Act 2026 has been signed into law by President Connolly, marking a major step towards resolving the long-running issue of the airport’s 32 million passenger cap. The legislation gives the Minister for Transport the power to make an order that could amend or revoke the cap, subject to the completion of environmental assessments required under EU law.
Minister for Transport Darragh O’Brien welcomed the enactment of the legislation, describing Dublin Airport as Ireland’s primary international gateway and confirming that work will now begin immediately to enable An Coimisiún Pleanála to carry out the necessary environmental assessments. The Act also protects daa’s live Infrastructure Application, currently under consideration by Fingal County Council. The application seeks approval to increase passenger capacity and deliver major infrastructure projects, including new passenger piers, additional aircraft stands and an Integrated Transport Hub.
According to the Department of Transport, these developments would support Ireland’s aviation growth strategy, improve capacity for both passenger and cargo operations, and strengthen Dublin Airport’s role as an international hub.
The legislation follows extensive stakeholder engagement and scrutiny by the Oireachtas Joint Committee on Transport. The Government says it will facilitate the sustainable development of Dublin Airport while balancing the rights of local residents with the needs of Ireland’s aviation, tourism and business sectors.
While the Act does not immediately remove the passenger cap, it establishes the legal framework needed to address the issue. The next stage will see environmental assessments carried out before any decision is made on amending or removing the restriction.
