Through December 21, 2015, Aeroplan is offering up to 40,000 bonus miles when you convert points from one of their partners into their program. Unfortunately American Express Membership Rewards transfers are excluded.
The bonus is cumulative, meaning you can transfer points in from various programs and earn the bonus. One of the more popular transfer partners that is eligible for this promotion is SPG. Normally 20,000 Starpoints transfer to 25,000 Aeroplan Miles, but with this promotion 20,000 Starpoints would equal 29,000 Aeroplan Miles and 40,000 Starpoints would equal 60,000 Aeroplan Miles.
- Bonus offer valid only on conversions made between November 16, 2015 and December 21, 2015 (11:59 EST).
- Maximum 40,000 Bonus Aeroplan Miles can be earned per Aeroplan Member.
- Conversion of Membership Rewards® points from American Express Cardmember accounts into Aeroplan Miles are not eligible for this promotion.
You can find the full terms of the promotion here.
