Well, i don't have the answer to your specific situation what I've been able to do in the past was 1) get the Avion card pick up 15k points + pay the fee; 2) switch to the no fee RBC rewards card; 3) 4 months later switch back to the Avion card pick up 15k points + pay the fee.

So yes, you can do product switches. However, I tried to repeat the process above a third time (i.e. get my third Avion card) and was shut down. They said I could get it, but no points. Also, I don't know if you can go from a premium card to another premium card, though I don't see why not.

This is a case where calling in is not a bad idea.
