With the infrequent service to MRU, and the low AONEX fares, I was wondering if it was possible to do a quick turnaround on the JNB-MRU-JNB flights, picking up a ticket in transit at MRU. According to the schedule, the incoming flight arrives at 15:10 while the outgoing one departs at 16:00.

The problem is that the JNB-MRU flight appears to operate only on Saturdays in March.
