Besides the surcharge regulations in certain ports, the benefit would be related to the logistics in how you plan your trip, which would be dependent on your individual circumstances.Thanks kangol. Do you know or anyone know, if there is any benefit in having your long 'stopover' ie the 10 months or whatever, in your home city (like you suggested) or in an Asian hub like appaz's booking above in KUL
eg. if you wanted to go to Europe on trip 1 followed by USA on trip 2, starting it in an Asian port means you have to finish there. So if you wanted to come home nonstop LAX-SYD (for whatever reason), you wouldn't be able to do that - you would have to go LAX-Asian port-SYD.
In the same example, if you start in Australia, have the 10 month stopover in Asia, you would be able to do the nonstop LAX-SYD on the way home.
Your positioning flights Australia-Asia could either be right before the OWA and right after - meaning you have to keep the 12 month rule in mind if buying a cheap(er) revenue ticket, or, have the positioning flights in the middle of the award, which would not be subject to the 12 month rule.
There is some discussion on surcharges here:
