What changed

The Irish Department of Justice has enacted amendments to the Criminal Law and Civil Law (Miscellaneous Provisions) Bill 2026, strengthening the nation's Passenger Name Record (PNR) regime. These changes extend the processing of PNR data to include flights originating from or destined for Ireland from within the EU, bridging a previous security gap. The amendments align Ireland's PNR system with a European Court of Justice judgment and reinforce strict controls on the usage of this data by the Irish Passenger Information Unit.

These amendments will enhance Ireland's ability to detect suspicious travel patterns and identify individuals involved in criminal or terrorist activities. Law enforcement agencies will now have broader access to PNR data for flights within the EU, in addition to existing international routes. Regulated entities, primarily airlines, will need to ensure their systems and data handling practices comply with the updated PNR regime, particularly concerning data collected for commercial purposes and its subsequent analysis by the Irish Passenger Information Unit.

What to do next

Review PNR data processing procedures to ensure compliance with EU PNR Directive and Irish amendments.
Verify data handling practices align with strict controls on PNR data usage.
Ensure systems capture and retain PNR data for all relevant flights (EU and non-EU).

Strengthening detection of suspicious air travel patterns

The amendments to the Criminal Law and Civil Law (Miscellaneous Provisions) Bill 2026 will strengthen Ireland’s ability to detect suspicious travel patterns and identify criminals and terrorists operating within the EU and travelling to and from Ireland by air.

Currently Passenger Name Record (PNR) data only extends to those flying to and from Ireland from outside the EU. The amendments will bridge that security gap and ensure Ireland’s PNR regime aligns with a judgment of the European Court of Justice of the EU on the EU PNR Directive, re-enforcing strict controls on PNR data usage.

The amendments concern the statutory regime allowing for the processing of PNR data by the Irish Passenger Information Unit within the Department of Justice, Home Affairs and Migration.

The collection and analysis of PNR data is a widely used law enforcement tool in the EU and elsewhere.

Additionally, PNR data consists of information provided by passengers, which is collected by and held in the airlines’ reservation and departure control systems for their own commercial purposes.
