I'll go further and say that not only has AA made us some generous offers, they're also offering us vastly improved service. It's still not where CP's service was in the heydays of the last century, but it's a big improvement over a year ago.
'Course I can only speak for J and F classes, as I'm still automatically getting upgraded on every single flight, sometimes even only as a mid-level AA Platinum (= CP Gold.) But's that's instructional in it's own right. I like to think I've repaid the favour by booking on AA whenever possible, since February, to the tune of 26 flights so far, and 5 more in the next week.
