Bump. Not sure exactly when the change took place, but all KA routes now seem to be offering CX codeshare designators which means (assuming you book using these, rather than the KA equivalent):

- Mileage earn for all OW scheme members.
- Use of The Wing / The Pier when departing HKG on a qualifying ticket or holding OW Sapphire / Emerald status.

Also great news as on routes like HKG/PVG, where the KA op services are 3-class, while the newly-introduced CX op flights offer only Y and J and on the inbound timings are useless if you're planning to connect on to another flight.

Not sure whether this means that xONEx tix can be booked on KA metal using the CX designator, I suspect not (at least not for a little while yet).

Hope the update is useful.
