I can tell you that I have been monitoring CX F award space pretty close for the past few weeks as I am super flexible on my departure and just wanted to find one F seat somewhere. Someone up-thread thought it was because of the Chinese New Year, but I will give my opinion that CX is blanket blocking all F partner awards right now. I have not checked their own program availability.
Many flights have plenty of F inventory leading right up to the day of departure and nothing is opening up for awards. While business award seats were and are opening when inventory is there, so in my opinion it has nothing to do with the holiday period and just that CX is not wanting to give away F seats to partners right now.
Thank you for the advice from everyone upthread. I have made a Qantas account and continue to search for any awards that might open up. I have to say though, having followed award space daily for the JFK-YVR route for the past two months, there seems to be a new filter or blackout in effect. It appears that all space gets locked out at the eleven day mark. Twelve days out, CX 865 will have economy 7+ / business 7+ / first 1 or 2 and then right at eleven days out it 0's out across all classes and stays that way until departure. Strangely, I can call AA and book award seats on CX 865 JFK-YVR-HKG without issue, but they are unable to see seats only on the JFK-YVR leg. One helpful agent thought this was an error and tried to hold JFK-YVR-HKG drop the second segment, but her system wouldn't process it.
