Years ago, airlines released award inventory 330 days out.
But they realized that only inventory that won't be sold for cash should be sold for points.
So now most award inventory seems to released in the 14 days before departure... after most revenue sales have been completed and an accurate forecast is likely.
Translation: Airlines give nothing away for points that may generate cash.
Not good for those that need to plan ahead.
