RBC offering 2x RBC Rewards points on AirBnB bookings until Feb. 29, 2016. Also, first time use gets you 7000 RBC Rewards points.
My wife and I each have a card. Might take advantage of this. If I can't use it for a booking that I actually want, might just do a cheap dummy booking. There's a room near my house for rent for $29/night. 0.5c per Avion (converted to AA) ain't bad at all.
