Please take pity on this *A FTer who has been jumping back & forth through the AA & CX forums trying to figure out the best miles to use/way to book the following award:

(Ideally) One Way: ANC-stopover in YVR- (CX metal in F ) - JFK in late Aug/early Sept

I'd be willing to consider a r/t if necessary or just getting from ANC-YVR separately. Or maybe even ANC-SEA (ferry) YVR-JFK? now you can see how confused I am

Given your experiences on availability, is this even feasible and if so which program would be best to use?

Also, iirc, FTers use both the BA or Qantas web sites to check on OW award availability, is 1 better than the other for this ?

fwiw, I've got AA and BA miles but am sure I could find whatever else would be needed.

I'm just hoping y'all could point me in the right direction so I can be more effective in my attempt to try out CX premium while visiting both ANC & YVR (and YYJ).

Thanks so much from someone who thinks the new UA will soon lead me straight to OW....
