In accordance with our Travel Conditions, tickets are non-refundable if you don`t travel for personal reasons. In case you are not present at the boarding gate in due time, or you lack the necessary travel documents, you will be declared no show and the ticket becomes non-refundable. This policy is also valid if you are denied boarding due to reasons non-attributable to the airline (for more information regarding the denied boarding you can find in Chapter IX of our travel conditions https://www.flyblueair.com/media/default/content/blueair_travelconditions_1april2022.pdf ).
If your flight was affected by a schedule change over 3 (three) hours or by a cancellation you can request a refund following the indication in the notification email. For more details please see What are my options in case of a disruption?
