Anyone know why the online RTW tool isn't offering the direct CX flight between JFK and HKG?

I am trying to integrate it into a DONE4 going westwards and all the options are BA/AA etc via London, Chicago, Tokyo etc...

There are several flights every day: CX 845, 841, 831, 889 and they are available on the CX website for the day I need... but I can't seem to be able to force the OW tool to see them.

I guess I'll end up calling a OW office and getting them to ticket?
