Booked another AONE to do a weekend trip to the UK once more
NRT-KUL-HKG // HKG-LAX-JFK-LHR-MAN // MAN-LHR-DOH-HKG // HKG-HND (Was really struggling to get a better option here, and since this will be after the year tier point reset, it doesn't matter that much - tried HKG-KUL-HND or HKG-BKK-HND, I may change later)

What I wanted to observe was:

1. NRT-KUL-HKG caused a lot of angst, the poor agent took about 20 minutes to get a combination that worked. That did actually end up with the route that ExpertFlyer suggested to avoid married segments, but its a long 10 hour stopover now rather than 2 hours
2. Agent was able to get this priced & ticketed in less than 10 minutes. Very impressive, considering I once waited on hold for two hours for a minor destination change
3. Though I have some AA codeshare remenant on the underlying non-AA ticket for the NRT-KUL flight. Hope that fixes itself without intervention...
