Record Passengers, Rising Standards: What the IAA 2025 Annual Report Reveals About the State of Irish Aviation

Ireland's aviation regulator has published its most significant annual account. The IAA 2025 Annual Report, released in June 2026, confirms 44 million passengers through Ireland's six airports in 2025. The IAA reported pre-tax profits more than doubling to €7.1 million on revenues up 22% to €45.6 million, without Exchequer support. Three challenges define the year ahead: the Dublin Airport cap, a maintenance engineering skills shortage, and accelerating drone integration.

The report rewards a constructive reading. Record passenger volumes and a strong regulatory balance sheet confirm that Irish aviation is operating from a position of structural confidence. The case for treating the IAA's annual findings as a board-level strategic input rests on what the data reveals about the gap between current performance and the conditions needed to sustain it across the growth decade ahead.

The consumer protection picture is notable. Despite a 10% rise in passenger numbers, the IAA handled 2,883 complaints in 2025. This is 35% fewer than in 2024, with 2,112 new complaints submitted. Of those upheld, 1,213 complaints were upheld, securing €795,500 in compensation and €334,471 in refunds. Security queues at Dublin Airport did not exceed 30 minutes on any day and remained below 20 minutes 99% of the time, which is a significant achievement at record throughput.

The Dublin Airport passenger cap remains the most consequential open issue. The IAA has been involved in legal proceedings on the cap's effect on slot allocation, with the matter now before the European Court of Justice. The Dublin Airport (Passenger Capacity) Bill 2026, introduced in February 2026, signals the Government's legislative intent. The IAA has pledged full support for cap removal, framing complete utilisation of Dublin Airport's infrastructure as a national economic priority.

Two forward-looking themes carry strategic weight. The skills shortage in aircraft maintenance engineering is a primary vulnerability: training costs and apprenticeship bottlenecks constrain the pipeline precisely when MRO demand is highest. The Government has committed to doubling apprenticeship places to 160 from September 2025. Drone activity is the second theme, drawing the IAA into European rulemaking and integration projects that will shape how unmanned aircraft operate in Irish airspace for the decade ahead.

Three actions follow. First, the Dublin Airport Passenger Capacity Bill must be enacted before the September 2026 slot window closes, converting regulatory intent into operational certainty for airlines planning Summer 2027 capacity. Second, the aircraft maintenance apprenticeship programme should be scaled well beyond 160 places, treating technician pipeline as a national strategic asset. Third, the IAA's drone integration programme should be resourced to match the pace at which unmanned aviation is reshaping Irish airspace.

The IAA 2025 Annual Report documents a sector at record scale: 44 million passengers handled safely, consumers protected, and a regulator self-financing without public subsidy. The unresolved cap and the emerging maintenance engineering shortage are the two issues between current performance and the full expression of Ireland's aviation potential. Addressing both with the decisiveness the sector has earned would secure the next chapter the IAA's 2025 data makes plain is within reach.
