This is the definitive WorldPoints thread. Best uses of points: Transfer to Aeroplan. - These transfers are 1:1. - They take around 2-3 weeks to complete. - There is no fee. - Even though the example mentions 220,000 miles, it only allows upto 50k at a time or something like that, so just use as many xfers as necessary (I did 2 at the same time and they both went through).
