So, if you go over the E50K threshold by 20% Air Canada would like to give you something to thank you for your patronage. If you go over the E75K by 20% you get something for your patronage. If however you are a SE100K, you need to go over your threshold by 50% to receive a gift.

Just another way Air Canada would like to say thank you to its SE members. I suppose they figure that if someone makes SE, they don't need any encouragement to fly with them. Thus, sending out the SE cards last.

Way to go Air Canada. You know how to look after your frequent fliers.
