I booked a *A award ticket which includes an NZ flight from AKL-SYD. There was no *I* availability on my date, so I booked into *X* (*A Economy Class award) for now.

I have been checking the for the *I* availability every now and again and I noticed that there seems to be none for the entire year. There were plenty of dates before, but a couple of days ago it was all pulled. Does anyone know why this is? Will it come back?
