In the past I have always looked at availability of award tickets (for the specific leg) to check upgrade availability. But today this did not work. I found available award tickets from DOH to HKG on the flight on which I am booked, but when I tried to upgrade the QR website (and the QR WhatApp service chat) told me there was no upgrades available. A consequence of this is that it is not possible to check upgrade availability before booking.

Has any one else experienced this? In the past I have always been able to upgrade if award tickets are available.
