As things stand in law, air passenger rights are protected by Regulation (EC) No. 261/2004, which covers the rights of passengers in instances of flight cancellations. Under the Regulation, if an airline cancels a flight then customers are entitled to a full cash refund wihtin 7 days. The Commission for Aviation Regulation is the statutory body in Ireland with responsibility for enforcing airline refund obligations. I understand that the Commission has already written to the airlines reminding them of their legal obligations. Anyone having difficulties securing a refund should contact the Commission. Further advice is available on its dedicated passenger rights website www.flightrights.ie.
