This is a revenue ticket on QR stock. I haven't seen that thread or rather didn't think to look there since my change was not directly related to COVID. Thanks for pointing that out. Looking at the policies it appears I can change to NBO without any upfare since it's within 500 miles of my original destination. That is, if my flight is a "UN" status. I tried searching for the definition of UN on their site and came up with nothing. Guidelines For Changing Ticketed Segments Changed to UN Status or TK Status Resulting In Misconnection

For any ticketed segments that meet any of the following criteria:

• Ticketed segment cancellations resulting with UN status
• Flight retiming resulting in ticketed segment(s) with TK status where the newly timed flight causes a minimum connecting time (MCT) violation or misconnection.
• Ticketed segment cancellations resulting with UN status and updated with new TK segment

You may re-issue to ticket using the following guidelines:

• May rebook onto alternative QR operated flight(s) that are:

- on the same route

- within the same country as original embarkation and/or disembarkation point

- within 500 international miles (TPM) from original embarkation and/or disembarkation point
