75k miles for HND-JFK in ANA's "The Room" Business Class in 2023 and 75k miles for IAD-HND in United Polaris a few months ago.

I had to cancel a trip in 2022 and Aeroplan offered the value of the ticket to be converted to miles. I can't remember the exact conversion, but I remember it was a good one with a bonus - the ticket was around $1,500 and I think I got like 160k miles from cancelling? Used that cancellation and the miles that converted from it to book the US-Japan flights.
