Also sounds like you may have flown air Canada. Ironically generally the worst use for Aeroplan points.I wish I could understand this stuff. I bought AC points at a discount and used them for a SYD-YVR return. As I was 20k points short I made up the difference with cash. The total cost of this ticket, cost of points plus cash balance, was considerably greater than the cash cost of my wife's ticket. I would certainly never buy another AC point, on sale or otherwise.
