Even though you can't transfer from every hotel loyalty program, Aeroplan offers an extensive list of transfer partners, including Starwood Preferred Guest, Marriott Rewards, and Hilton HHonors, among others, allowing you to receive the transfer bonus by transferring from a combination of these partners. Note that conversions from American Express Membership Rewards are not eligible as part of this promotion. Also note that you don't need to register for this promotion, and the bonus miles will post to your account 7-10 days after the eligible transactions are complete.
Aeroplan has consistently been viewed as a cost-effective program for transferring points to its partner brands, and despite a devaluation of the program in December, you can still find some great travel options — you're also able to redeem your points to cover taxes and surcharges. Starwood is a great option for cashing in Aeroplan Miles since members can earn 5,000 bonus points for every 20,000 SPG points transferred. For example, if you were to transfer 160,000 Starpoints, your Aeroplan balance would be exactly 200,000 (with a 40,000 SPG bonus), and you'll receive the maximum transfer bonus from Aeroplan, netting you 255,000 Aeroplan Miles.
