Sorry to bump an old thread but the topic is appropriate.

Just want to be clear, I have a 2 pax J YYZ-TPE-ICN-TPE-YYZ AE reward for the end of February. It is a single PNR but two different ticket numbers. Being a teacher, my wife does not want to take the risk of travel (plus the possible 14 day quarantine on return) during that period. Is is still possible to split this PNR in two, or even better, just cancel her ticket? I obviously will monitor the situation for myself but I can wait a lot longer until making my decision which is why it would be good to only cancel her ticket. I guess worse case I can split then cancel.
