I now have a theory - and will get to test it out when/if they process the claim.
When I try and use the
Points calculator to check points for DOH-DUS, it finds Doha fine as FROM, but when trying to put Dusseldorf into the TO city, it says no matching city. My theory is that the calculator references the same tables used for crediting, and if the route / partner combination has not been loaded, then no points get credited, as well as the calculator not showing anything.
All the data points mentioned up thread now show up in the points calculator with a rate for QR. My theory is that when the claim is made, the route is added by someone, and thereafter the points calculator shows it, and in theory future flights on the route should post.
Will be interested to see if DOH-DUS (and vice versa) show in the calculator after this gets sorted. DUS is known to the calculator (at least for DUS-LHR on BA).
