Thanks DUF!

I have had a look at your suggestion but can't make the USA part work; the ORD-HNL flight goes via LAX or DFW and consequently gives me one too many flights in that continent.

I take on board your suggestion of not using a segment on BNE so we will have another look at that.

As to the QF FFP; will this be of use to me back in the UK when I probably won't be flying Qantas again?

Yes you are right about being quick; we want to take advantage of the discount so will be booking this weekend, but mainly I will just be glad to have the route sorted out so that we can start planning the fun part! (Which for me is not the flying.....)
