Advise on RTW routing
 

Late next year I will be retiring and plan to use a FC RTW award on Sky Team. Our tenative plans include the following stops:Depart from West coast of US travel west(direction of travel can be changed) West coast to Fiji, on our own from Fiji to AKL and Syd. Visit Australia then to ICN to visit Asia then onto Bombay and then onto South Africa, return to US. Any suggestions how to substitue Papeete for Fiji then on to Australia, using SKY team.Based on routing, to travel on Skyteam to Australia from PPE would require PPE to LAX to ICN then AKL or SYD.
We are planning foer this adventure to take 4 months.
Many thanks in advance for your help.
