Can anyone surmise what's going on with HKG-DEL pricing and availability?

CX fares are absolutely out of whack, 3x the price of 9W and AI on the same non-stops. These routes also used to be pretty good in terms of award availability but have recently dried up entirely (for two routes on which planes almost consistently go out 50% empty). Have seen a lot of jumping around in terms of fares filed and unfiled over the past month (for a week, one way J to USA was pricing with discount business fare bucket. Next week, all dissapears).

Just looking at the fares filed between HKG and DEL shows only full fare fares? What's going on?
