Upgrade refund automatic when cancelling a booking?
 

I may have to cancel an upcoming trip due to corona.

The booking includes a leg that I upgraded using miles - will these be automatically refunded or do I need to call to cancel the upgrade first?

Thanks.

Partly answering my own question.

Had to cancel an upcoming trip to Asia as result of Corona - corporate TA cancelled the booking but I had to call to ensure the miles used to upgrade one of legs were refunded. Phone agent could still see the relevant details and the miles were back in my account within 10 mins.

As an aside it looks they might have waived the cancellation fee (this was a Bus Flex booking).
