Aer Lingus ID & ETA Rule Changes
Aer Lingus has implemented stricter identification rules for UK flights, now mandating passports for all non-Irish citizens, even within the Common Travel Area, to streamline operations and minimize delays. This significant change coincides with the full activation of the UK's Electronic Travel Authorisation (ETA) requirement today, February 26, 2026, which impacts 85 nationalities previously traveling visa-free.
