Thanks guy. I value the miles at about 3-400 GBP because I'd only do it if the RBC 50% bonus shows up up. I can also throw in some SPG miles if that 30% bonus reoccurs. I'd think BA business would be substantially than the charter clubs classes LHR-YYZ at $700.
Round trip would be a good idea but I wanted to do a stopover in Iceland on the way in and it seems Icelandair at is the most economically way of doing that because they have a direct flight to KEF then to LHR for C$420 (economy)for both legs! I don't have access any of the flight routing programs so if someone sees a better way let me know!
*sigh* I miss flying biz to london for work
PS if you have any travel tips for London/Geneva/Iceland etc let me know! And I assume Priceline is the way to go for cheap hotels?
