I notice CX availability has been "cleaned up" on at least one route.
There was phantom F availability TYO-HKG in April that is gone now, replaced by CX main.
There was J availability HKG-JNB (that I didn't try to book) in April as well; it's gone, replaced by main as well.
Still searching other routes to see what/if other changes have occurred; hopefully in some cases more F/J availability and not less.
