When you opt in to receive text messages from Aeroplan, the earning opportunities come to you - wherever you are. And now you'll get between 100 and 1,000 miles just for signing up! First, be sure to add your mobile phone number to your Aeroplan profile. Then, text “join” to 27767 to get started.
Note: Each member is only eligible once. Members who are already signed up to receive Aeroplan text messages are not eligible for this offer. Once you sign up, you’ll receive a confirmation text message, followed 24 hours later by another text message letting you know how many miles you're getting.
Based on the feedback I got from my friends (including myself) who signed up for this offer, all of us (~ 5 people) only got 100 Aeroplan miles. Not much, but still good if your Aeroplan miles is about to expired.
