re: Qantas "oneworld" award (140K/280K/420K) Discussion
I did something similar last year and was surprised on how easy it was to book on Qantas.com.
10 Flights, 29,000 miles, 3 stops, I think you can have up to 5 stops.
Go to bookings and just keep adding flights in a RTW direction, the points keep adding until you get to 140,000 and then it stops.
Ah I should finish my trip report and post it, I got a gentle reminder that I had not finished it on the weekend.
