In case the refund amount isn't reflecting then you'll fill a Refund form . It is often done just for the traditional ticket and not for the Flying Blue Reward tickets. If the tickets are booked during a group then all the tickets are going to be cancelled. If you would like to cancel one ticket you've got to contact Air France cancellation Customer Services.

The refund is completed consistent with the airfare conditions and doesn't include service fees because it is non-refundable. just in case you've got checked in then you're required to cancel the check-in before requesting for flight cancellation.
