Lot of confusion in this thread about ANA awards.
ANA release some award seats at calendar open. Often only 1 seat in J and F. These are snapped up instantly by people with other points currencies and so only scraps are available once Velocity's award calendar opens up, especially on routes to North America where demand is through the roof.
Then ANA releases some seats at the last minute, usually 14 days from departure.
Rarely is there anything released in between. Exceptions include aircraft swaps and new routes.
