Dublin Airport clocks 4 % passenger growth as transfer traffic surges

Dublin Airport handled just under 29 million passengers in the first nine months of 2026, up 4 % year-on-year, according to figures released this morning by airport operator daa. September alone saw 3.34 million travellers, matching last year but including the three busiest September days ever recorded, the busiest being 13 September with 128,600 passengers. The data show robust demand on trans-Atlantic routes—493,000 passengers in September, 3 % higher than 2025—as well as a 37 % jump in transfer traffic. Managing Director Gary McLean attributed the spike to Ireland’s EU Presidency events, high-profile golf tournaments and the return of student and corporate travel after summer. Terminal-usage patterns are also shifting: Terminal 1 carried 17.4 million passengers year-to-date, while Terminal 2 hosted 11.6 million, a split that informs capacity-planning for the airport’s €5.6 billion expansion blueprint currently under government review. For corporates the numbers translate into busier security lanes and car parks through the autumn shoulder season. Mobility teams should encourage travellers to pre-book Fast Track and parking, and to watch for updated guidance on U.S. pre-clearance enhancements that daa says are ‘critical’ to sustaining North-American growth. More broadly, the figures reinforce Ireland’s continuing importance as a European hub despite capacity caps. With passenger totals likely to top 34 million by year-end, pressure is mounting on regulators to lift the annual cap from 32 million and fast-track infrastructure approvals.
