So I thought I'd share my somewhat long and complicated story with Finnair and trying to get compensation for delayed flight.

I was going on business-trip to Bangkok with the new Finnair A350 on 25th of march 2016 (AY089). The flight was due to technical problems with some fuel indicator delayed and postponed until the next day. Finnair offered passengers accommodation during the night and got a new plane, also a350, in the morning. We arrived at BKK about 20h late.
I did not know that I could get compensation for this until April, and I then wrote to Finnair how to get compensation. Then it started.
Finnair claimed extraordinary circumstances and told me the plane was new and that it probably was a manufacturing problem. Therefore they would not pay any standard compensation (600€) but offered me 200€ travel voucher. I declined the offer and referred to EU-court rulings and EU regulations. They still declined and in May 17th Finnair told me that I can contact KRIL, which I did. After about two months Finnair replied to KRIL that this was a business trip and that KRIL is not allowed to handle business passengers. KRIL told me to contact trafi, so I did. Another two months passed before Finnair replied to trafi and still called extraordinary circumstances. Trafi then did their magic and 10(!) months later I got reply that recommended Finnair to pay the standard compensation.
I contacted Finnair again with this information, and one month of trying to get contact with them they replied that trafi only recommends and that they have won a case in court in Germany with the same flight.
Long story short. Does anyone know about this decision from the German court? And any advise how to proceed?

Sorry for the long post.
