Over the last 4 trips I have been VERY surprised about the wrong information I have been given regarding the seat availability.

Yesterday on AC 3241 (CP operated)from MIA - YYZ I was told the flight was oversold by 20 seats in the back, J was full. I was on the later flight and wanted to get home so I still went to the airport to standby for the flight. The agents there told me probably not a chance to get on, but since I was there I waited. I got on the airplane and was surprised to see the plane had lots of empty seats.

The previous week I also took a CP flight from YWG - YYZ and was given the same story - over sold flight. When I went to check in the agent told me they may be looking for volunteers and I told her I would be interested. About 20 minutes before departure I asked the gate agent how it was looking (i.e. has everybody checked in) and she told me that it looks like they won't be needing any volunteers. When we finally left the plane had at least 50 open seats on a 320.

Has anybody else noticed that load information, especially on the CP flights is way out or are my last few CP flights an isolated incidents?
