I'm trying to push the limit with a *A North American reward. While I don't think I can do the whole thing on one ticket, I'm wondering if I can only buy one OW leg seperate from a 25,000 North American ticket (likely 40k in J)

BOS-YYZ-<7 days>-YYC-<7 days>-MIA/FLL-<7 days>-BOS

While I don't have access to routings, I see two options:

1. YYZ-YYC-BOS, with a stopover in MIA/FLL.
2. BOS-(YYZ)-YYC-MIA, with a stopover in YYZ

Can anyone help?

Thanks! -O
