getting to south sudan

I will be getting to South Sudan by plane.  The flight will leave at 14:55 at LAX and will fly to JUB in South Sudan with two stops in FRA and ADD.  The flight will take 35h and 35m.  I will then drive to the town that Athok Alauk lives in.  I will be leaving 4 days after the flight to take the same flight with two different stops Cairo international in Egypt. and MUC.
