Maybe AC has found the key. Why court thousands of SE's when you can just court the VIP of a company that holds the purse-strings. I suspect that there are a ton of SE's (at least in Canada) who work for a company which has a preferential deal in place with AC. I also know that in terms of the Federal Government, AC is "preferred" as it is a Canadian carrier.

Some people, like yourself, have choice. Others, maybe not so much..
