Revenue at the semi-state company rose 6pc to €536.1m, compared to the first half of 2024.
The company said total passenger numbers in the first six months of 2025 were 4pc higher, at 18.6 million.
The DAA has in recent weeks been gripped by boardroom turmoil, with a deal already having been hammered out that could see chief executive Kenny Jacobs leave his role in January with a €1m package.
However, that deal has yet to go before Transport Minister Darragh O’Brien and Public Expenditure Minister Jack Chambers for sign off.
Dublin Airport’s charges remain among the lowest of major European airports
The DAA has also warned that a “fair outcome” in the Irish Aviation Authority’s process of determining passenger charges at Dublin Airport for the 2027 to 2031 period is “critical”.
“Dublin Airport’s charges remain among the lowest of major European airports, which is increasingly unsustainable given these pressures and the significant operational and capital investment needed to deliver the standard expected of Ireland’s national gateway and maintain quality across Dublin and Cork,” according to DAA chief financial officer Peter Dunne.
He added: “As we approach the next regulatory determination, a fair price outcome will be critical to protecting service, resilience and connectivity for passengers and the wider economy.”
Just under 17 million passengers used Dublin Airport in first six months of the year, 2.7pc higher year-on-year.
A passenger cap at Dublin Airport is effectively paused until legal challenges, in relation to efforts by the Irish Aviation Authority to ensure the cap is adhered to, are heard in Europe.
The Government is also now drafting legislation to have the cap removed. The cap limits the number of passengers that can travel through Dublin Airport to 32 million a year. The airport is on track to handle about 36 million this year.
The DAA’s earnings before interest, tax, depreciation and amortisation (Ebitda), slipped 1pc to €160.8m in the first half of the year.
Operating costs jumped 10pc to €375.3m. The DAA said it boosted internal operating capacity and third-party services to support operational resilience and enhance service quality.

Of income, non-aeronautical revenue rose 7pc to €247.6m as increased passenger numbers resulted in a higher spend at its food and beverage offerings and retail outlets. It also benefited from digital pre-book services.
The DAA’s ARI unit, which has contracts to operate airport retail services in a number of countries, saw its pre-tax profit jump 64pc to €21.8m.
The Irish Aviation Authority (IAA) is undertaking a review of a passenger advisory group as it prepares to determine the charges that Dublin Airport can levy between 2027 and 2031.
The IAA said the PAG was established to “improve the understanding of what is important to passengers”.
It explained: “The PAG is a consultative forum to represent the interests, concerns, and experiences of passengers.”
