I'm trying to book this: PDX-ORD-LHR-NBO-LHR-MAD-DOH-BKK-TYO-HNL-PDX
Initial flight and transatlantic segment are on AA and the HNL-PDX segment could be AA or codeshare on AS. The LHR-NBO-LHR-MAD-DOH segments are all on BA/IB. I'm also trying to accumulate enough tier points and flights to get to gold on BA (I have 385 TP currently).

The oneworld tool was accepting it all the way through entering passenger information. The LHR-NBO-LHR segments were direct on BA and there were no complaints about exceeding allowable number of arrivals/departures between the middle east/africa (I know the tool has some kind of bug here). A few hours later I went back to the tool to adjust a date and the BA flights to/from NBO disappeared and it only offered me a connection via DOH which triggered the middle east/africa issue. I moved dates around and still couldn't see the BA flights. Of course expertflyer shows full D availability and oddly doesn't show the DOH connections.

#1. Assuming the tool works again tomorrow, I could change the initial flight and transatlantic segment to BA. If I go to book, will it go to BA or will it default to QF even though there are no QF flights? I want to avoid ticketing through QF.

#2. Was the tool mistaken in allowing the LHR-NBO-LHR in the first place and I don't fully grasp the africa/europe restrictions?

#3. Do I have enough flights on AA metal to be able to call the AA RTW desk and skip the tool? Or should I try through BA since at the moment, most of the flights are with BA/IB?

Thanks for any advice!
