Your choices when a flight is cancelled
If your flight is cancelled, the airline must offer you the choice between a full refund within 7 days, or re-routing to your final destination at the earliest opportunity (or at a later date at your convenience).
Compensation for cancellations
If you were informed of the cancellation less than 14 days before the scheduled departure date, you may also be entitled to compensation up to €600, depending on the alternative flight offered and the flight distance.
