The European Commission’s Implementing Decision (EU) 2026/1970 enters into force today, 28 September 2026, setting detailed technical standards for how national ETIAS units and carriers must access, amend and erase traveller data held in the central ETIAS system. Although Ireland is outside Schengen and not bound by ETIAS, the decision matters to Irish aviation because airlines operating out of Dublin, Cork and Shannon will soon have to transmit passenger data to Schengen border authorities before departure. Carriers must upgrade their departure-control systems to meet the new interface specifications and ensure they can receive real-time ‘board/not board’ messages for visa-exempt third-country nationals. Ground-handling agents at Irish airports will therefore need training on the revised workflows, and travel-management companies must prepare to collect ETIAS authorisation numbers from passengers whose itineraries include EU/Schengen destinations after the system goes live later this year. Failure to verify an authorisation will expose carriers to fines of up to €5,000 per traveller in certain member states. Data-protection officers should note that the decision tightens retention rules: information retrieved from the ETIAS Central System must be deleted within 24 hours unless needed for an ongoing assessment, potentially requiring changes to API storage practices. While Irish passport holders are exempt from ETIAS, non-EU residents in Ireland – including many multinational assignees – will need an authorisation for short trips to France, Germany or Spain. Industry bodies such as Airlines for Europe estimate the compliance burden at €1.3 million per mid-size carrier. Stakeholders are lobbying for a phased enforcement period, but today’s decision confirms that no further delays are expected.
