According to operator daa, a record 3.08 million travellers utilised the two terminals throughout the month, a 4% rise over the same period the previous year.

This takes the overall number of passengers who have visited the facility this year to 25.8 million, an increase of 5.3% over the same period in 2023.

Daa stated that it still anticipates exceeding the 32 million passenger annual cap, which was imposed in 2007 as part of the planning approval for the second terminal, by as much as one million this year.

However, it issued a warning that although October is expected to be busy as well, several airlines have lowered their operations at the airport because of the unpredictability of the scenario around the cap.

"Daa has long been vocal about the potential negative impacts of the cap, warning it could lead to significant job losses and harm Ireland's economy and international reputation," stated Kenny Jacobs, daa's chief executive.

"Regrettably, our predictions are becoming a reality. Ryanair is cutting routes, Aer Lingus is warning of job losses, while Emerald is likely reducing its fleet and may cut its Dublin to Donegal route, all of which leads to economic harm and reduced connectivity for Ireland."

Dublin Airport has applied for planning permission to construct additional facilities that would allow the maximum to be raised to forty million annually, but it would likely take years for a decision to be made.
