May have answered one of my own questions, I can find on aa.com now NRT->LAX(JL) LAX->ORD(AA) ORD->DTW(AA) for 80K, so the additional leg is at no additional cost. Although I could not find NRT->ORD (JL) and ORD->DTW(AA), is there anyway for me to have the reservation changed, or is that not going to be possible? Thanks again!
