I had an upcoming flight scheduled mid-August. It was booked using points with the Chase Ultimate Rewards travel portal. I received an unprompted email the other day from Chase that the flight was cancelled and that my points have been refunded (they were). Given what I had been reading above it seems like I'm pretty fortunate...

However, I had also purchased around USD 500 worth of seat assignments directly from Swiss via credit card. I submitted an online refund request for this. Any feedback on the best way to get this refund processed?
