This sharp increase has prompted the aviation industry to launch a new campaign as the airport braces for its busiest time.

In just the first five months of 2025, the Dublin Airport Garda Station has responded to over 30 cases involving unruly behaviour by passengers. This follows an upward trend, with 2024 figures already showing a 50% increase over those recorded in 2023.

The most frequent incidents involve offensive conduct, obstructing or assaulting authorised personnel, and intoxicated passengers aboard flights.

With over 500,000 passengers expected to travel through the airport this bank holiday weekend, the aviation sector has launched the #NotOnMyFlight campaign to raise awareness and promote responsible travel behaviour.

Assistant Garda Commissioner Paul Cleary, of the Dublin Metropolitan Region, stressed the risks posed by disruptive passengers, including flight delays, missed connections, and danger to crew and fellow travellers.

“There is no excuse for anti-social or aggressive behaviour,” Cleary said. “While most passengers behave appropriately, Gardaí remain ready to intervene to maintain safety and order at our airports.”

Katie Morgan, national secretary of trade union Fórsa, highlighted the impact on aviation staff, calling the issue a critical health and safety concern.

“Our members have experienced the effects of unruly passengers firsthand,” Morgan said. “Aviation workers deserve a respectful and secure work environment. This campaign helps ensure their safety is treated as a top priority—just as they prioritise the safety of the travelling public.”
