My case is finished.
- Feb16 | ?? | HEL-PEK | 6h delay | 150€ voucher | manufacture fail of A350 | ??
Step 1 - contact Finnair, only 150 € voucher
Step 2 - contact KRIL, Finnair wrote letter that I wasn't a consumer but it was a B2B transaction.
Step 3 - Trafi, 9 months later recommended that Finnair should pay 600 €. forwarded the letter to Finnair and they payed.
Perhaps they were difficult in the beginning because then it was my first Finnair flight (no single tier point), and now platinum?
