The Irish Cabinet has approved drafting legislation to remove the longstanding passenger cap at Dublin Airport, a move that could reshape the country’s aviation and tourism sectors. Once enacted, the Dublin Airport Passenger Capacity Bill will give the Minister for Transport the power to amend or revoke the existing cap of 32 million passengers and prevent future caps from being imposed.
Speaking ahead of the Cabinet meeting, Minister for Transport Darragh O’Brien said Dublin Airport, as a key national infrastructure asset, should not be constrained by local planning authorities. “It is a critical employer. It is a critical piece of infrastructure for connectivity and foreign direct investment. We can’t have a situation where there is a false inhibitor to growth in place anymore,” he said. He added that residents in the surrounding areas had been considered in the planning of the legislation.
Minister for Tourism Peter Burke highlighted the role of the airport in supporting Ireland’s tourism strategy. “Lifting the cap is a key strategic piece for our country in improving our infrastructure,” he said.
The passenger cap has been a point of contention for years. Introduced in 2007 as a planning condition for Terminal 2, the cap was initially set when 23 million passengers used the airport. Passenger numbers have since surged, exceeding the 32 million limit, though the cap has not been enforced as legal challenges brought by airlines were referred to European courts.
Dublin Airport operator daa welcomed the move, describing the cap as “outdated” and saying it had artificially restricted growth. The company stressed the importance of global connectivity for economic prosperity, employment, and investment. The daa is also pursuing infrastructure expansion, including new aircraft stands, aprons, improved access, and car parking, with plans for a 40 million passenger capacity under review by Fingal County Council.
Passenger numbers at Dublin Airport continue to grow. Last month, approximately 2.48 million people passed through the two terminals, a 14% increase from the same month last year and the highest January figure ever recorded. In 2025, the airport handled a record 36.4 million passengers, up 5.1% from 2024, marking the tenth consecutive month of growth.
The legislation has drawn mixed reactions. Green Party leader Roderic O’Gorman argued that passenger numbers are the wrong metric to regulate, advocating instead for oversight of noise and carbon emissions. Labour TD Conor Sheehan questioned giving planning authority to the Minister, emphasizing environmental concerns.
Children’s Rights Over Flights criticised the plan as “reckless and irresponsible,” citing Ireland’s climate emergency and the aviation sector’s rising emissions. The group noted that since 1990, emissions from aviation have grown by 500%, now accounting for roughly 10% of Ireland’s total greenhouse gas emissions.
The government expects the legislation to be enacted later this year, fulfilling a Programme for Government commitment and removing a regulatory barrier that has shaped Ireland’s busiest airport for nearly two decades.
