I assume Mindpearl have no more access to information than the AA agents in the RTW desk?

The calculations are done back-office within AA so potentially neither the RTW desk nor Mindpearl have access to them. Certainly the AA RTW desk claimed to have no access to the breakdown and they say they asked for a little info (I asked if they might find out how much from the SIN-xDOH-JNB part of an RTW) and weren't given an answer.

I'll have time to play around with a 2nd xONEx re-route from next week so will try at least a few 1-2 segment change variants to get a sense of the pricing difference and how that maps to ITA info across various airlines (one or more of AA/JAL/LAN/Cathay/BA/QF) and will try and summarize anything useful I can discern in a few weeks.
