YYC-LAS, T-24, $149 (Taken x2=298)
J6R2Y6, T+ Flight Pass (M fare)

Took the upgrade as a special treat for my wife and I on Vegas vacation. Used the iPad App to do the upgrade. Went all the way through, put in the credit card and when I submitted the card, I got an error "An upgrade is no longer available." BUT, the upgrade went through, because when I finished the check in, I checked the seats and we were in J. No credit card authorization when through, no charge was made, and we did indeed get our J seats. So, $298, but really $0.

I guess for all the times I cursed AC IT, I guess I have to stop now. I keep expecting a sudden "Oh by the way, we forgot to charge you" but for now I'm happy. And if they catch it later, oh well.
