but if when purchasing the ticket one specifies B class and it books into B, I would expect PZ to credit as ZB, even when crediting to United. I guess the lesson here is booking class can be different than fare basis. I probably knew this but haven’t run into it lately.

You can try and send in the ETKT receipt and see if they will change it.
PZ is more important for sure but requalification was also a goal. I’ll have them try and email with receipt and boarding pass (though boarding pass just says business but at least the ticket number still matches on the BP matches the receipt).
