I flew the DOH-HKG route recently on CX ands the flight was almost empty in J.
This is clearly the end of the JV and even of the strategic partnership (whatever CX says). Basically CX will not codeshare on any QR metal except the QR flights DOK-HKG. CX sees little bemefit in this partnership except feeding QR pax to Europe, and possibly losing many of these pax for CX own flights to Europe.
