Was your flight cancelled?
If your flight departed from or arrived at a UK airport and was cancelled, you may be entitled to a refund or re-routing, and in some cases compensation under UK261 rules — particularly if you were given less than 14 days' notice and the cancellation was within the airline's control. Always check directly with your airline first.
Figures are compiled from live flight status data captured throughout each day. Coverage may vary and some cancellations could be missed; treat these numbers as an indicative guide, not an official record.
