Back in post #160 I said I was trying out various ex-KRT itineraries to try to convince Mrs pandaperth that we should buy one. Well she's agreed, and so I am trying even harder to get the tool to price things up. (though I fully expect in the end I will have to use a Canadian TA to ticket)

Thought I'd share what I've been finding out. Maybe others can contribute what they've learnt too.

OK my basic itinerary is: KRT-xAMM-YUL,YYZ-xHKG-PER-HKG-XIY,IKT-DME-AMM-KRT. The first part (KRT...PER) is to get us home from our African holiday next March/April. Then the second part is to get us to Xian (terracotta warriors) and Russia for Mrs pandaperth's birthday trip next August. Ending up back in KRT, and hopefully starting another RTW from there.

S7 has not loaded its schedules beyond March next year, so I have removed the IKT-DME segment and all being well will add that later (paying the change fee)
The good news is that the above itinerary (minus the IKT-DME segment) prices up in the online tool.

Now it gets tricky
There are some segments left over and when I add them, sometimes it prices up, sometimes it doesn't
It seems to me that if you return to the same airport after some intra-continental segments then the tool fails (whereas inter-continental returns do not fail - in the itinerary I have HKG-PER-HKG and that works)

So adding PER-BME-PER or PER-BNE-ADL-PER to the above causes failure
So does HKG-PNH-HKG and HKG-NRT-ICN-HKG
But adding PER-BNE-MEL-SYD-CNS works
As does adding SIN-NRT-ICN-HKG

Note: all the testing I have done has been on ex-KRT itineraries, so it's AA that does the pricing (the url is http://americanairlines.eu.amadeus.com)
YYMV with other ticketing airlines
Note also that I of course have not tried to actually pay for any of these - and it is known that failure can occur at that point too
