Is it SEK 100k on the Blue Amex for the 50% Voucher? On the Platinum it is SEK 150k and on the Elite SEK 150k and another one at SEK 300k.

Anyway, it is not a free C voucher. It is a 50% off of any award booking for up to two pax. And I do not think they take away all award space. Actually I had the voucher for 4 years in the row and I just used it once for a long haul C award for two, for the other years timings just didn't work/no award space and I needed to burn two of them on intra-European economy and one even expired unused.

I'm getting close to get my second this year and I actually have no idea how to use it.

I think a bigger problem in terms of free award space are the US programs with crazy credit card sign up bonus incentives. Sign up a card, spend a few thousand dollars, get enough miles for a C award and repeat with the next card.

But I agree, Denmark (btw. Germany and UK as well) offer very poor credit card programs.
