Well, looking at your experiences I still have to wait a while for my supposed "expedited" miles return.

I wanted to rebook the 2nd segment of our reward ticket that some geniuses had dropped together with the cancelled first segment regardless of the fact that it was still operating (for now) in 3 months time. Awesome SQ.

Not keen to transfer in additional miles just because it takes ages to return miles for screwed up ticket cancellation. I'm even content on having to wait for the cash from the stopover fee, taxes, etc., but how hard can miles return be?

Even LH, not recently known for customer excellence, was able to return miles for a cancelled flight within 8 days (taxes + crazy YQ I'm still waiting) and sent an email about the settlement details. The only way this works with SQ is going to ION office where staff are very good, but not really in the spirit of distancing during COVID-19 times.

So we wait some more a for the miles and in the meantime we booked flights on another carrier using miles from another FFP. That could have gone to SQ, but alas it wasn't meant to be I guess.
