No, the refund is applicable for any type of award ticket.
Asiana Refund Policy says After cancellation of the booked ticket, the refund amount will credit within 10 to 15 working days.
The refund amount will get the same bank account that was used for the duration of the flight booking.
If passengers have selected non-refundable flight tickets on the duration of booking so on that condition, passengers will not get any type of refund after cancellation.
