I'd advise the OP to be very careful about the timing of the decision regarding ORC. It's not obvious to me that ORC will apply, especially if a refund is paid for the cancelled flight. If OP is close to the end of his/her TP collection year, be sure that if ORC hasn't been granted by then, some alternative MR is done to guarantee the required number of TPs. A small extension to the year might apply, but again be sure to meet all deadlines for this so that status isn't forfeited in the end due to not receiving TPs for the flight that became a long shared taxi ride.
