With Christmas traffic already ramping up, Dublin Airport operator daa released a five-point travel advisory on 14 November aimed at smoothing passenger flows during ongoing terminal refurbishments. The guidance comes eight weeks after the airport completed a €200 million installation of CT-based “C3” scanners, allowing passengers to leave laptops in bags and to carry liquids up to two litres.
The advisory urges travellers to: 1) check lounge availability—several facilities are temporarily closed for renovation; 2) pre-book Fast-Track security and lounges via the Dublin Airport App; 3) use public transport or be dropped at the far end of the Departures road to bypass construction bottlenecks; 4) monitor live flight updates through the app, especially during Ireland’s volatile autumn weather; and 5) review security regulations at destination airports, many of which still enforce the old 100 ml liquid limit.
From a corporate-mobility perspective the biggest win is predictability: average security-queue times at Terminal 1 have fallen from 24 minutes last winter to just 8 minutes in early November, according to daa data. That enables tighter connection windows for regional commuters flying onward to the US pre-clearance facility or to London for day-return meetings.

Yet the transition is not friction-free. Airlines report a spike in secondary screening for passengers originating at airports without CT scanners who attempt to transfer at Dublin with liquids exceeding 100 ml. Multinational travel managers should update pre-trip briefings and booking-tool pop-ups to flag the disparity.
In addition to security upgrades, refurbishment work continues in the airside retail zone, temporarily rerouting foot traffic. daa forecasts 33 million passengers for 2025, up 6 % year-on-year, and says the new scanners add capacity equivalent to two extra security lanes—critical as Ryanair and Aer Lingus plan record winter schedules.
Travellers transiting Dublin for EU assignments should also note that the airport’s e-gate expansion, originally slated for October, has slipped to Q1 2026, so non-EEA assignees may still face manual immigration queues during peak periods.
