Aer Lingus has formally switched to a strict “passport-only” policy for all flights between the Republic of Ireland and the United Kingdom as of Monday, 30 March 2026. The carrier confirmed that Irish passport booklets or the newer Irish Passport Card – as well as full British passports for UK nationals – are now the sole acceptable forms of identification at check-in and the boarding gate. Long-used alternatives such as Irish or UK driving licences, Garda age cards and workplace photo-badges are no longer valid. The change – first sign-posted in February but now fully in force – standardises documentation requirements across the airline’s network and aligns with tighter UK Border Force checks introduced ahead of the nationwide roll-out of the Electronic Travel Authorisation (ETA) scheme. Aer Lingus told customers the new rule should cut last-minute gate refusals and speed overall turnaround times, particularly during peak corporate travel hours on the Dublin-London and Cork-Manchester shuttles. Business-travel managers are being advised to update company travel intranets immediately. Because children under 16 are also covered by the measure, family members accompanying assignees on short-term projects will each need a passport or Passport Card, ending the practice of travelling with a parent’s documentation. HR teams arranging “Friday-to-Monday” commuter assignments should note that new hires awaiting passports cannot use temporary ID letters; airlines have no discretion. Non-Irish, non-UK nationals flying from Irish airports to Britain face an additional layer: if they do not already hold UK immigration permission they must secure a UK ETA before boarding.

For anyone facing this new administrative hurdle, VisaHQ’s Ireland portal (https://www.visahq.com/ireland/) can quickly determine whether you simply need a passport or also require an ETA, and their online tools let both individual travellers and corporate coordinators submit and track applications in one place—helping to keep tight travel schedules on track.
Aer Lingus has embedded ETA reminders into its booking flow, but immigration advisers warn that processing can take 72 hours; travellers making short-notice visits for sales pitches or site surveys could be stranded if they ignore the requirement. While Aer Lingus Regional services between Belfast and Great Britain remain domestic UK flights and therefore outside the policy, the move is nonetheless a pivotal shift for the Common Travel Area. Companies running cross-channel operations should audit travel policies, ensure staff passport validity (minimum six-month recommendation) and budget for the €35 Passport Card fee where appropriate. With Easter and the summer conference season approaching, proactive compliance will be essential to avoid costly missed meetings and re-ticketing fees.
