Aeroplan is running a contest vote for the “best of” in select popular cities with the Around the World Contest. Voting on each city will give you entry into three prizes of 200,000 Aeroplan miles. You can vote here.
However, if you go via the facebook app, you can also get additional 1,000 miles when you do a transaction with any of the partners which they have a special offer with.
Today is also the last day to book Marriott awards before the devaluation takes place. You can check hotel category shifts here.
Air Canada has also released the new North American fare structure seen as below in the screenshot. Changes are now $200 for transborders, which matches all the other US carriers.
Also I had a post on the Lifemiles devaluation. Check it out here.
