When do you need to go? Are you checking both J and F and also to JNB and open jaws?

I've never had problems booking to CPT/JNB a few months out. The availability changes frequently, even on a daily basis.

There is usually good availabilty back from CPT on the dayflight. The overnight flight is much harder to get in J and F. We have managed to get overnight both ways, which is good as we have a little one who sleeps very well.....
