Business and leisure travellers who routinely move between the UK and Ireland under the Common Travel Area (CTA) have been advised to carry photographic identification after the British Foreign, Commonwealth & Development Office (FCDO) amended its Ireland travel advice on 24 September 2026. While the CTA continues to permit British and Irish citizens to travel without passports, the new advisory stresses that air and sea carriers, as well as Irish immigration officers, may ask for either a passport or recognised photo ID before boarding or on arrival. The change reflects tightening carrier-led security checks introduced at a number of UK regional airports and ferry ports this summer following recommendations from the UK National Cyber Security Centre and Ireland’s Garda National Immigration Bureau. For corporate mobility managers the clarification is timely. UK-based assignees accustomed to flying to Dublin on short notice report a rise in denied boarding incidents when travelling with no photo ID or with expired documents. Airlines including Aer Lingus Regional and Ryanair have updated terms of carriage to state that “government-issued photographic identification is mandatory for all UK–Ireland flights regardless of nationality”. Ferry operators Stena Line and Irish Ferries have introduced similar conditions for foot passengers. The practical impact is limited for travellers who already carry passports, but cross-border commuters who rely on driving licences or company ID cards should review whether those documents meet carrier requirements. Mobility teams are being urged to brief employees, contractors and visitors, and to update pre-trip checklists to include valid photo ID. Employers should also note that non-British/Irish nationals transiting the UK en route to Ireland must still obtain any necessary UK visas even when remaining airside. The FCDO emphasises there is no change to the underlying CTA treaty—British and Irish citizens retain the right to move freely and work in each other’s jurisdictions—but the operational guidance aims to reduce confusion at departure points and ensure smoother flows during the upcoming mid-term travel peak.
