Hi JK, I understand one way tickets are always gona be more expensive than return, but I'm comparing oranges with oranges, and Qantas one way ticket business ticket is priced beyond belief, with almost equivalent terms and conditions i.e. not discounted tickets. In fact, some of the others are not only cheaper but also more generous cancellation clause (Qantas GBP 200 vs SQ US$100).
I'm moving back to Australia so this is will be one way trip.
