Over 2.3 million passengers travelled through Shannon Airport last year, the highest number in 16 years and a 9% increase on 2024.
Passenger growth last year was boosted by new routes and expanded services.
Ryanair added a fourth based aircraft at Shannon, representing an additional $100m investment in the region, and also announced new destinations including Madeira, Lapland and Madrid, as well as increased frequencies on over 10 routes.
Shannon Airport said it will operate 40 routes in 2026 to destinations across Europe, the US and UK. This includes five new routes in the summer schedule - Rome, Warsaw, Madrid and Poznan with Ryanair, and Frankfurt with Discover Airlines, a Lufthansa Group subsidiary.
It will also see with increased frequencies on existing services, including the Aer Lingus Boston route.
Plans are in place for over €40m in investment this year, with projects including a full upgrade of the airport's immigration and baggage halls, upgraded taxiways and a new thermal wrap of the external arrivals area of the airport terminal which will be key to helping the group reach its energy efficiency targets into the future.
The interim CEO of The Shannon Airport Group, Ray O'Driscoll, said that 2025 was a really positive year for The Shannon Airport Group.
"We achieved our highest passenger numbers in over 16 years and invested over €20m in projects that have a very tangible benefit to both passengers and our sustainability goals", he said.
"This brought our overall investment in the group to almost €200m in just over a decade. We're looking forward to an even more ambitious 2026, during which passengers will have the choice of 40 routes, the highest number operating from Shannon Airport in 17 years," he added.
2025 saw the completion of significant sustainability and infrastructure projects at the airport including the launch of Ireland's first airfield solar PV farm, which is set to generate up to 20% of Shannon Airport's electricity needs.
Last year also saw 1,000 new passenger car park spaces created, bringing to over 5,600 the total number of spaces on offer at the airport, across five short-stay and long-stay car parks, in which over 200,000 cars parked in 2025.
An expansion of the airport's existing European passenger boarding gates was also completed.
Over the past 10 years, The Shannon Airport Group has developed over a million square feet of space across the airport and its commercial property business.
This year will see the construction of Blocks Y and Z at the Shannon Airport Business Park, adding a combined 100,000 square feet of energy-efficient space.
"We are far more than just an airport, and we are proud of the role The Shannon Airport Group plays in driving tourism, trade and economic growth," Ray O'Driscoll said.
"As we look ahead to 2026 and beyond, we remain committed to delivering the excellent customer experience that we are known for, expanding our route network, and continuing our investment in sustainability and infrastructure as we strive to be best-in-class," he added.
