I'm researching flights for my wife and I using UR points from IST-JNB in November of this year. I've noticed there are a lot of dates with Economy available, but Business class availability has only several dates in May and June of this year and abruptly has no availability for the rest of the year beginning July 1.

Does this mean that there is going to be no more business award availability the rest of the year?

Or does it mean that maybe they haven't released availability for the second half of the year yet?

This is my first time searching for TK award, so any prior experience is greatly appreciated. Thanks
