Please take a look at this.
I have this F RTW trip plan for May. Please take a look. Am I maxing this out. Can someone give me a idea about putting all of the domestic flights on the back end of the trip with max miles? I would then fly out on CX to HKG from LAX. Thanks in advance. Here it is- smf to dfw to bos to lax to hkg to kix to hkg to dps to hkg to syd to per to mel to akl to syd to hkg to lhr to ist to lhr to dxb to lhr (lgw) to dfw to anc to dfw to smf. It is all legal according to AA. Prices out at 9k.
