Hi. Anyone with recent experience using Qcredits to upgrade from Economy to Business? I considering booking a flight end of December for OSL-DOH-JNB. I have 40 Qcredits, which should be enough to upgrade at least one of the segments. The economy fare is class N, which is eligible for qcredits-upgrade. However, how sure can I be that the upgrade option will be available after booking my ticket? Any way to find an indication before booking a particular flight? Any feedback is appreciated.
