so many "if's" and issues
- upcoming 9/1 change to only 1 stopover, if that matters to you
- YYZ to Europe options are really limited, sometimes it's better to just pay for CASH or wait for deals, or a mix of both (miles there, cash back, etc...)
- There's no telling on ANY availability, you just wait and see and hope
- Either way, RACK UP points ASAP!! AMEX Plat 60K, AMEX Biz Plat 75K (both via referral), and TD Aeroplan VISA should be doable. Even better if you can do 2 player mode (refer each other)
Good luck
