Why is there no Cathay Pacific award seat availability via Alaska Airlines Mileage Plan?

There appears to be no Cathay J availability with Alaskan Air miles from Australia to Hong Kong and vice versa in the second half of 2021. Error message on all searches.
Is there any reason for this ? QFF shows availability with Cathay to Hong Kong and Japan.

You can’t search Alaskan website for Cathay availability, you need to call

Phoned Alaskan - no availability at all.

Typically, Alaska has less award availability than OneWorld partners like Qantas. Previously, the rule was that you would have access to 1-2 seats less than Oneworld partners so check how many seats is available as an award with Qantas. If they did fully block off availability to Alaska, then it’s a bummer I’m afraid.
