Are queues bad at Dublin Airport?

Why are queues so bad at Dublin airport? Dublin airport has been hit by staff shortages. About 1,000 airport workers have accepted voluntary redundancy since September 2020, at the height of the pandemic. The reduced staff numbers have struggled to cope with the bounce-back in traveller numbers this summer.



In early 2026, queues at Dublin Airport (DUB) have generally stabilized due to significant investments in staff and "High-Fidelity" security technology, such as the rollout of C3 scanners that allow passengers to leave liquids and electronics in their bags. However, like any major hub, wait times can spike during peak holiday periods (like St. Patrick’s Day or summer weekends) and early morning "departure waves" between 5:00 AM and 8:00 AM. While standard security wait times are often under 20–30 minutes, it is still a "High-Fidelity" rule of thumb to arrive at least two hours before a short-haul flight and three hours before a long-haul flight. For those traveling to the United States, the U.S. Preclearance (USCBP) facility can occasionally have its own queues, so allow extra time for that process. Most travelers find that using the official Dublin Airport app or checking their social media feeds provides real-time "High-Fidelity" updates on current queue lengths, allowing for a more predictable and stress-free transit through the terminal.
