Due to the weekend, it took RBC to update its website to display the promotion below.
November 1, 2014 and Decembre 31, 2014, when you convert your Avion points into Avios points, you will also receive a 50% bonus. Avion converts to Avios at a 1 to 1 ratio and you need to convert a minimum of 10,000 Avion points. Therefore, the 10,000 Avion points will give you 15,000 Avios points.
This is quite an amazing deal and I am glad to see that it is happening again in 2014. Generally you will see this promotion about twice a year.
Generally British Airways reward flights charge a fairly high tax and fuel surcharge, so I would keep in mind that British Airways is a member of the Oneworld airline alliance, so you can use your Avios points on reward flights of any of the other member airlines. Personally, I would be looking into American Airlines or U.S. Airways reward flights as a Canadian.
