Dublin Airport Capacity Bill Faces Scrutiny Amidst Airline Concerns
The Oireachtas Committee on Transport is currently examining the Dublin Airport (Passenger Capacity) Bill 2026, which aims to lift the existing 32 million passenger cap. Airlines are voicing strong opinions on the proposed legislation, with Aer Lingus warning of potential capacity cuts and fare increases if the cap is not removed swiftly. Ryanair has also weighed in, arguing the cap is unlawful and hinders growth.
Aer Lingus Warns of “Catastrophic” Impact
Aer Lingus CEO Lynne Embleton told the committee that enforcing the passenger cap would necessitate a reduction of approximately 4.4 million passengers, representing over 12% of current traffic levels. Embleton described the cap as a “historic anachronism” and warned of a “catastrophic impact on connectivity, on the airport, and on the wider Irish economy.”
According to Aer Lingus, the enforcement of the cap would also disrupt supply and demand dynamics, potentially leading to increased airfares. The airline emphasized the importance of swift enactment of the Bill to provide “certainty and stability.”
Embleton further explained that the current legal proceedings have temporarily prevented severe capacity cuts, but a ruling from the European Court of Justice in the coming months could lift the stay and reinstate the cap for the summer 2027 season.
Ryanair Cites EU-US Agreements
Ryanair CEO Eddie Wilson argued that the 2007 passenger restriction is “unlawful” and contravenes the EU-US Open Skies Agreement. Wilson also dismissed claims of excessive noise from residents near the airport as “bogus,” stating that local opposition should not impede national economic growth.
Ryanair warned that failure to abolish the cap could result in Ireland losing out on new aircraft and routes, particularly to the UK and other EU states.
Legislative Context and Current Status
The Dublin Airport (Passenger Capacity) Bill 2026 was approved by the Cabinet last month, seeking to overturn the 32 million passenger limit initially imposed as a condition of a 2007 planning permission. However, the restriction remains suspended pending a decision from the Court of Justice of the European Union.
Despite the suspension, Dublin Airport experienced a record 36.4 million passengers in 2025.
Committee Hearings and Stakeholder Input
The Oireachtas Committee on Transport is holding a series of hearings to scrutinize the Bill. In addition to Aer Lingus and Ryanair, representatives from Airlines for America, the International Air Transport Association, and Airports Council International Europe are also scheduled to present their views.
Economic Impact
Aer Lingus estimates that the loss of one million passengers from Dublin Airport would result in a €1.4 billion decrease in spending, €320 million in lost taxes, and up to 37,000 fewer jobs.
