Without going into all the details, I am planning to go CDG-AMS-JNB-AMS on a ticket that is routed CDG-AMS-JNB-AMS-CDG. If I stay in Ams and just let the final Ams-CDG segment drop is there any chance that for some reason I won't get the miles? If it matters, I will be flying the day after my arrival Ams-B0s-Ams on another ticket and don't want to have to go all the way back to Paris and then come back. The alternative is simply booking Ams-JNB-Ams and taking the train Paris-Ams on the way out.

Thanks for any suggestions/advice
