AnotherWorld, did you find the flights you wanted?
It's funny, the Qantas website has a codeshare with United, to SFO. Yet I haven't come across a codeshare with United on the SQ website. It's probably there but I just haven't found one!
Yes agreed. I should have articulated what I wanted to say better. What I'm saying is that SQ and UA are in *A yet I haven't come across a United codeshare on the SQ website. I'm sure it's there and I just haven't found it. I thought I would have at least seen one to ORD! Yet, QF and UA, being in separate alliances, have partnered together with their codeshare. I was just assuming that being in the same alliance SQ & UA would have codeshares like QF and AA do. I hope that makes more sense.
But yes what would said is perfectly logical. And it's time for me to go to bed!
I'm actually pretty sure that SQ and UA don't codeshare. Just being in the same alliance doesn't mean you have to codeshare.
As for the original question, I believe that it needs to be *A metal (or a KF partner) for KF miles to be earned.
I have a feeling that the OP has the definition of a codeshare confused.
QF offers connections with UA, but it doesn't place a QF code on these flights. That alone doesn't mean it's a codeshare. The image below shows he AA flight as a codeshare, but the UA flight isn't. View attachment 34515
