On a separate note - I have AMM- SYD currently as an award- I plan on booking an australia to nz flight, nz to ppt, and ppt back to the states as well, all probably on AA partners. I'm not 100% sure of the dates or routing of the middle flights - is there an advantage of booking this all under one award (is that even possible?) as a bunch of separate legs? Would that allow me to change the routing of the middle legs without change fees, or am I no better off than just booking as separate itineraries?
Total trip will probably be something like:
AMM-AUH-SYD EY
SYD-CNS QF
CNS-SYD-CHC QF
AKL-PPT TN
PPT-LAX TN
