So I had a AB ticket for early november purchased via Supersavertravel (Svenska Resegruppen). I know, I know, don't use OTAs as they take no responsibility. Supersavertravel didn't contact me even after the flight was definitely cancelled, and after a terrible back-and-forth on their phone-system they refused "involuntary rebooking" and said I should make arrangements myself.
When they so bluntly disregarded their obligations, my only option was to ask my CC issuer to refund based on non-delivery of items purchased. Now, 2.5 month later, everything was refunded.
So it ended well for me too. I do hope the CC company did manage to extract that money from supersavertravel. It would make me even happier knowing they had to pay the price. Note to self - stay away from these travel agents.
