Aer Lingus Mandates Passports on CTA Flights

Aer Lingus joins Ryanair in requiring passports for all Common Travel Area flights, tightening ID checks across routes between Ireland, the UK, and associated islands. This policy shift ends reliance on simpler ID options like driver's licenses for intra-area travel. Airlines implement the rule to enhance security and comply with evolving border protocols. Travelers must now carry valid passports to board, avoiding boarding denials.
