I received a refund calculation for a reward ticket this morning after 96 days when 120 were promised. I'll post an update when the money comes in.
The calculation shows a refund that is too high right now but I'll wait and see what is actually refunded. At the moment it shows a full refund of the taxes and fees for the cancelled flights, but I initially changed the ticket to an open ticket and then rebooked with lower fees (ANA). So the refund should only be the difference between both, not the full amount.
