Do not forget CX and QR out of OSL, ARN, CPH (SK, KL, and LH connections where appropriate), etc. Also AY often have some good fares that will combine with QF flight numbers.
If looking at QR, watch out for the AY leased planes, if QR more than AY is your objective.
Typically anything routed via LHR will be slightly higher.

And for QF, if SCs are your objective, watch out for any route that QF considers "competitive" even on OW, as you will be slugged with a 50% penalty in SCs.
