Best way to fly YYZ to LON on points
I'm new to the forum and using points transfers to get maximum benefit. My fiance and I are going to travel to London in August/September following with a flight to Frankfurt and then Frankfurt back to Toronto. I currently have the below points available for booking flights and I would like to fly business class ideally .
RBC Rewards Points - 650,000
SPG Points - 60,000 (just opened)
Aeroplan - 15,000
I have done some looking and thought maybe Cathay Pacific would be a good choice to transfer points to but I really don't know what's going to be the best option for me. I'm hoping someone with experience with these programs could give me some tips.
