Almost. It took several back and forths before eventually getting in LH's refund queue, as in the beginning they would only offer me a voucher. With AF/KL I have no experience, but a voucher that can only be refunded after 12 months is not a proper monetary refund, but rather an interest-free loan to the airline. As far as A3 is concerned, they still staunchly refuse to refund the flights they unilaterally chose to cancel even though no restrictions were in place at that time.
I am in no way a SAS fan, rather the opposite. I have been, and still am, critic of the path they have taken, their treatment of their elites, their Business class catering, etc... Yet I cannot but give them kudos for never denying me my right to a full monetary refund of my cancelled flights, even in this mayhem. Personally, the way an airline (or any company for that matter) treats me means a lot to me, and this is something that I am going to keep in mind in the future..
