Aeroplan agent couldn't do anything to check availability. EVA agent said they can't see SAUA availablility and said Z was not available. Still not bookable via Aeroplan or Asiana. EF and KVS show I availability and CS+ respectively; in these circumstances, I could have easily upgraded via Aeroplan already. Not sure what's going on.

BR upgrade inventory is Z class. This includes EVA own mileage upgrade and electronic certificate. But it doesn’t make all of the Z inventory for SAUA upgrade. Those are I bucket (which is subset of Z). Thus there are cases where Z class is available but SAUA won’t clear.

I did a demo of this last year at a Chinese travel group on FB. EF showed Z only but no I. SAUA didn’t work.

If I class is available but Aeroplan can’t open the ticket online. Just call. Please make sure it’s per segment.
