I flew AMS-BSL-BCN on Saturday on paid Y upgraded to C using points. My online statement shows it now as Z class - ineligible for points.

The Qualiflyer phone centre promised to sort it our but it is not good if their systems do not recognise the possibility of using points to upgrade.

Irronically, I once recieved an operational upgrade on a short SN flight in the past and they credited C class points.
