I have noticed lots of reward availability for early June appears to have appeared today.

I have been looking for months to upgrade my J return to JNB and this morning BA.com had W, J and F availability for both flights daily flights on both my outbound and return dates having only had 2 W tickets available yesterday on one of the return legs.

Also a colleague had been looking for J / F availability from NYC and found that he suddenly had plenty of choice.

Not sure what has lead to this change of events but was warmly recieved in my office!
