Couple of more questions while playing around with the admittedly quirky online tool. That CPT is the main purpose of the trip means rules limit me somewhat, but the tool seems to be allowing me to fly from Europe to CPT then to asia via DOH. For example, both of these were valid in the tool...

Oslo - London - Cape Town - Johannesburg - Doha - Hong Kong - Hanoi - Tokyo - Chicago - Los Angeles - New York - Chicago - London - Oslo

Oslo - London - Cape Town - Johannesburg - Doha - Muscat - Doha - Hanoi - Tokyo - Chicago - Los Angeles - New York - Chicago - London - Oslo

I wasn't able to get it to price alternatives, like my preferred routing via DOH, and then bypassing EU/ME when departing South Africa to satisfy the rules as I understand them when including South Africa. Something like this:

Oslo - Doha - Cape Town - Johannesburg - Hong Kong - Hanoi - Tokyo - Chicago - Los Angeles - New York - Chicago - London - Oslo

I'm trying to maximize my AA earnings somewhat, with getting to/from CPT. After the first stop in Chicago, (basically home, the rest is to use up the ticket, and possibly build in another mini-trip. Not sure how to best mazimize it, depending on what I book, I should have at least one more segment to use.

Thanks all for all of the expertise here.
