FlyerTalk we were able to find out the full details.
The offer is for all of you RBC Avion cardholders (Infinite and
Platinum) and runs until June 8th. Despite the BA devaluations and only being 30%, this
promotion is still a decent deal as BA Avios are a great option
for flights to
Asia (via Cathay Pacific), short to medium haul within North America
(short haul offer is great on Alaska Airlines or American Airlines
see this post here) and even though huge surcharges are
added to their UK/Europe redemptions they can still be an alright value
because of this bonus based on your spend with the credit card
(see my post about Earn & Burn
for an explanation). As always though with any frequent flyer program
you will have to be flexible in your options when redeeming due to seat
availability issues (ie it may be hard to get tickets to Europe in
Summer etc.) so take this into consideration before transferring.
Also consider reading our post on How you can easily get a free flight between Toronto and Dublin, Ireland (pre taxes/fees) or 4 flights for $240+fees
as this transfer bonus will work well. With the 30% you only have to transfer 20,000 RBC Rewards points to get to the 26,000 Avios level to redeem for these Dublin flights. Compare this to the 65,000 RBC Rewards points it would take to get the same flight and you can quickly see why there is value in the BA program. Heck if you have 65,000 RBC Rewards Points that's three flights to Dublin and back!
