ANA or Aeroplan
My Wife and I did our honeymoon to Thailand all on points last November. ANA and Aeroplan have the most generous redemptions. Business Class on ANA in November was 110k a ticket. Aeroplan which is AirCanada's rewards program I believe, is either 80 or 90k for BizClass. Book far in advance as the rewards seats fill up. Other carriers are well over 150k or 200k a ticket. Singapore I think is 600k for their comparable ticket. Time of year plays a roll with the ticket amount it could +/- 10k in points. MR transfer at 1:1 on both plans.
