Airline RTW tickets are often real bargains, are put together by a couple of airlines - they permit you to take any flight on their route system (long as you don't backtrack).

Since Australia is practically on the other side of the world from Europe or North America it works out the same to keep traveling in the same direction as it costs to return.

A typical price for a South Pacific RTW ticket costs around Aus $3000 US $2000.

Restrictions are:
You usually must book the first sector in advance therefore cancellation penalties apply.
The total number of stops you are allowed are limited.
The tickets are valid from 90 days up to a year.

An alternative type of RTW ticket is put together by a travel agent using a combination of discounted tickets from a number of airlines.
