I am trying to find a LONE in March PVG-FRA-TXL-GDL-PVG
I can find flights for all segments except CX/KA is never offered out of PVG.
Even adding HKG as a separate stop does not force CX or KA.

EF shows L class availability for both legs PVG HKG FRA

It won't be a big problem, as I will just ask our travel agent to do it, but it seems strange that CX is not even offered on PVG HKG
