Redeeming oneworld multicarrier award through Asia Miles

[niyiaw]

So I finally racked up 230k Asia Miles which I'm turning into a bucket list tick off flying in J around the world. Although I got caught out with the points devaluation since the goal posts moved so now I'm capped at 20000miles. So far I can get from HK to North America and through Europe to Japan but I'm struggling to find any flights from either Tokyo or Osaka to HK from Nov 2024 onwards (would be happy for a seat in Y for the few hours as long as I can complete this itinerary). I thought Cathay releases out flights 360 days ahead? Or are they released in batches and I should wait until the year rolls over? I'm just worried the transpacific and transatlantic flights will be snapped up if I wait too long.
