No flying on weekends due servicing and training. Lubumbashi aircraft will come off GRJ next year and do JNB - LUB - KIN - LUB -JNB and then an overnight Kigali.
The long GRJ turnaround due slots into JNB but changed already.
CRJ 200 times used initially before decision on M.77 - M.82 cruise or not.
Extra time added to JNB GRJ as GRJ ATC insists on the step down approach / descend in the hold.
