Regulatory plans to enforce a 25.2 million passenger limit on airlines at Dublin Airport next summer have been confirmed. The move is expected to incite legal objections from airlines which face potential curbs at this crucial node as a consequence. Last month, the Irish Aviation Authority (IAA) suggested this threshold to prevent the airport’s traffic from exceeding the contentious limit of 32 million passengers per annum, set by planners in 2007. The IAA reaffirmed on Monday that it would restrict airlines to a “seat capacity of 25.2 million passengers for the summer season of 2025”, spanning from March until October. This decision aligns with the preliminary resolution made last month and the suggestion from the airport’s proprietor, the State company DAA. Legal resistance from airlines is probable, especially if it leads to having relinquish their current departure and arrival slots at the airport. Aer Lingus and Ryanair have already petitioned the High Court to reconsider a limit of 13 million passengers enforced for this winter.
