The Aer Lingus Cancellation Policy varies based on the type of ticket purchased and fare conditions. Passengers with refundable fares can cancel their flights and receive a full refund, while non-refundable tickets usually qualify only for a refund of government taxes. Cancellation fees may apply depending on the route and fare class. Travelers must cancel their booking before the scheduled departure time to remain eligible for any refund. In some cases, Aer Lingus may allow free cancellations or refunds during schedule changes, disruptions, or special circumstances.
