Being relatively new to XONEs, I would appreciate some advice from those in the know.

1. What is the significance of "transit without stopover"? Does this have implications for the number of segments that can be booked?

2. What is the significant of flying A to C via B but with the same flight number all the way (eg. QF107)?

3. Is my reading of the rules correct such that the point of origin in Australia does not need to be the final point (ie. termination)? For example, departing from Brisbane, travelling around the world, and finishing the whole trip in Darwin.
