Hmm... no love getting AA code for JNB-MCT... but I could (and probably will) do the MCT turnaround at the end (which atleast according to mileage monkey is still a valid itin).

So it should look like CPT-LHR-DFW-ANC-DFW-YVR-JFK-HKG-BOM-HKG-DEL-NRT-SYD-LHR-MCT-LHR-NBO

Also, thanks for the heads up re "managing" the booking agents. Always a good tip. I'll defnintely have the flight numbers, dates and timings at hand before I sit down to make the call.
