I would like to book a trip from Sydney to Vancouver some time next year, using my ff points. Does anyone know how many ff points I would need (economy class) for these alternatives:

1. Syd - Lax with Qantas, and then Lax to Vancouver (sorry, I don't know the code) with Alaskan Airlines (I think, in the Qantas website). Round trip.

2. Syd - Hkg with Qantas, and then Hkg to Vancouver with Cathay Pacific (or Syd - Hkg - Vancouver with Cathay Pacific). Round trip.

3. One way Syd - Lax with Qantas, then Lax to Vancouver with Alaskan Airlines; one way Vancouver - Hkg - Syd with Cathay Pacific.

Thanks in advance.
