Planning my next RTW and am tempted to try AY HEL-PVG with a stopover followed by the new QF flight PVG-SYD.

Two questions:

1. Do AY codeshare with any other OW carrier on this route? [a BA/AA/QF designator would bag me bonus mileage]

2. I've read that AY is re-fitting its J cabin - when is this likely to be completed for this route?
