hmmm... I just repriced an Eastern Sun pass, and it now comes out to about $120 higher than what I paid last December 31. Given that GST has actually gone down 1% since that time, works out to around $25 more per segment. Not sure if that is a fuel surcharge that wasn't being applied last time I purchased, or if Air Canada snuck in a price increase sometime over the past 8 months.
Still worth it in my books... but not quite as good a deal as it was previously.
