Other Middle East and Africa Frequent Flyer Programs - JNB transit

Its related to another thread. Its HK-WDH (Windhoek) via JNB on CX then SA. Anyone has a rough idea how much time it takes to check in at the SA transit desk in JNB at about 7am? I need to make the connecting flight at 930am. would I have enough time? I was told that I don't have to go through immigration, its correct right? and CX could even check my luggage (I dont plan on check any anyway but it's good to know)?

Thanks Jon

The entire transit procedure at Joburg takes no more than 10-15 minutes to complete. It is entirely painless. Just follow the signs.
