You're welcome pye1201
For those of you who are wondering, the full itinerary is:
...just under $AUS18k
...I had no idea we could do so many BC miles for so little...
Hate to burst your bubble, but we did a DONE4 last year for just under AUD8K for two tickets

(purchased in Oct'12 when it was really cheap ex-KRT and the AUD was high)
