I flew AC this week - the first time in years - YUL-ORD-YUL. It reminded me what a good airline it is - at least compared to US carriers
I think my view of AC really changed since all the changes were being made to Aeroplan - no credit for lower fare classes, date/time change fees, strangely high award redemption levels (more than 2x) when availability is limited, expiration date for miles, etc. I just did not see any point flying it with all these negative changes.
I just thought it ironic that the "Loyalty Programme" actually made me less loyal to AC
