If Aer Lingus Cancels Your Flight

When an airline cancels or significantly changes your flight, U.S. Department of Transportation regulations require the airline to provide a full refund to the original form of payment — including ticket price, taxes, fees, and any paid extras — regardless of fare type.

Under DOT rules, a "significant change" includes: arrival delayed 3+ hours (domestic) or 6+ hours (international), a change in departure or arrival airport, additional connections, or an involuntary downgrade to a lower class of service.

The refund must be issued automatically within 7 business days for credit card purchases or 20 calendar days for other payment methods. Airlines may offer travel credits or vouchers as an alternative, but must inform you of your right to a cash refund. You are not required to accept a voucher.
