Air Canada is running their Earn Your Wings promotion.
If you registered early (before September 24) for the promotion, earning 1000 Aeroplan points is easy.
1. (If you haven't already), create a new Facebook account (so that your posts won't annoy all your friends).
2. Using the link on the Air Canada Earn Your Wings website, make posts to your Facebook account about how great the promo is. Maybe split those posts over a few days.
This worked for me; I earned enough RaceWings points to generate 1000 Aeroplan miles. And I annoyed 0 friends, because I have told 0 friends about that particular Facebook account.
If you did not register early, you can still earn enough points to almost reach the 1000 miles threshold. One transaction of almost any travel activity (hotel stay, car rental, flight) should be enough to get you the 1000 point bonus.
