Stringer, I guess you are planning on using KLM. If you connect you need to get a boarding pass to get you to the gate and verify for the flt. to Jo burg.. At the end of the E- concourse there are plenty of kiosks or agent to get you to check in.. procede to the KLM dep. gate and show them your SBY boarding pass and wait to be called. If you plan to spend some time in AMS you would need to check in with KLM agent in the dept. terminal, go thru customs and to the gate.. I think we fly non stop from ATL so that could be another option..have fun..
