Hi Gardyloo,
Thanks for response.
My routing hasn't changed a lot from above but is now:
ACC-xLHR-HKG-PER-MEL-BNE-LAX-DFW-YVR-JFK-YYZ-MIA-LHR-MAD-LIS-LHR-JNB
I called the RTW desk guy back and he agreed the price seemed wrong he put a note in the system for pricing to correct it - hopefully they agree with him.
As a side note does anyone have a suggestion on an alternative for the YYZ-MIA-LHR (schedule change on YYZ-MIA has kyboshed what was a perfect MCT). It needs to be a Friday afternoon out of YYZ and connection to LHR using AA metal so I can utilise an EVIP

. The LHR-MAD sector departs at 11:05 T3 on Saturday so it all needs to make that connection - of course max miles alway helpful

.
