thanks again

this routing seems fine to us dropping the durban - johannesburg part and take the flights within australia

just a few questions:

in januari i like to fly from santiago to papeete and beginning februari to sydney
this flights are full in m class
should i take the risk by taking an open date if that is possible and do airlines open some extra seats in this class or can i take for this part a sort of upgrading
(world traveler or so with B.A
in the worst case if everybody says no
i can take a 5 continent through n america to sydney does this flight have stop overs in the pacific ?
