Rtw ticket or buying flights when and as?

Hey I am planning a trip for september and plan to keep going till the money runs out. I have put it of and put it off but have decided to just go for it.
To actually make it happen i booked myself on a volunter project not far from bangkok to work with elephants.

So my plan is after 3 weeks of volountering i thought i would head back to Bangkok then travel up to laos and travel overland over laos, vietman and cambodia.
From cambodia fly back to Bangok and travel down to singapore overland then fly over to NZ to work for 6 months
Maybe see abit of malaysia brifley depending on money

I can\'t decide what type of flight ticket toget as Idon\'t really want to be against time?
Orginally i was thinking of just buying tickets when and as but after looking into that i didn\'t think that was making best use of my money .

So then I thought I could get rtw ticket with very few stops, buying internal ones were needed from air asia of somewere. could this be a good way of doing it?

My problem is all the ones i have looked at or made up you have to put in dates and i don\'t want to be tied as im not sure how long to give each place.

Would a rtw ticket be cheaper or would you recomend buying tickets when and as? Is it expensive to fly from South East Asia to NZ? Reply to this
