SkyTeam airline KLM has issued a €40 discount code which you can use for Air France, KLM, and Delta flights departing from Germany with a base fare (excluding taxes and fees) of at least 160€. This discount code can be used both for economy and business class tickets.
You have to book on the German KLM site (klm.de). Luckily, that site can be displayed in English, so it really should not be an issue.
Unfortunately, for many flights, especially within Europe, the base fare (without taxes and fees) is less than €160. On longer flights, you can more easily redeem this discount code. More details about the discount code can be found on the landing page:
Air France and KLM have been one of the largest airlines in Europe since their merger. Their extensive range of European and long-haul flights via their hubs in Paris and Amsterdam offers all kinds of opportunities to use these coupons.
Here are some deals that you could get this €40 discount on:

In this case, the redemption of the coupon is only possible through the KLM website. Don’t worry though, as Air France and most Delta flights can also be booked through KLM.
You can redeem a coupon once you get to the payment details. Then simply enter the code under Enter a voucher number or discount code.
Note: This specific voucher can only be used on the German KLM site! If the code is found to be valid, the value will immediately be subtracted from the total.

Blue button offering the coupon is labelled wrongly: 25 Euro (instead of 40 Euro as mentioned several times within the text and on KLM-landing page ). Embarrassing…
Thanks, W.Z.. I’ve changed the label.
