I don't think conversion to either BA or AA is worthwhile if you have E or SE with AC. For instance 100,000 RBC points is worth $1300 towards an airfare. If someone is travelling to Europe they can get a T+ ticket for less than that most of the time and between 7 and 9K miles on a RT;double that if chosen in your tier package. If you get an U/G its another bonus on top of the AE miles you collect towards the yearly status race.
Converting to BA or AA where most here are unlikely to have status makes it very difficult to get seats at times when most people want them.
On the other hand if one converts
yah?? I got a CX award from my BA points in F from YYZ-HKG

I forget the exact amount but the fees were around $40. So for that same award on AC I assume the fees would be $400.
You keep collecting AP miles so you leave those awards for the rest of us. Miles going to AP are EXPENSIVE to use... figure out how to get awards into other programs.
I called RBC and they cannot post miles for this promotion till Oct 26th.
