I, for one, have cancelled my CIBC Aerogold card because I am sick and tired of their rude service and their poor chargeback service (obvious things like ebay purchases with empty boxes). Heck, even with MBNA all you have to do is sign something and you get a credit...

Anyways, I digress. Maybe someone from this recent Ash cloud event had an Aeroplan ticket paid for by Amex and can chime in?...
