I was flying on AC 881 from CDG to YYZ on the 18th with a final destination to YVR on AC 115.

The CDG to YYZ flight was delayed by 178 min unfortunately. I heard that it may be a mechanical error but unsure how to check.

When I went to board the delayed AC 115 flight from YYZ to YVR, I was told that the flight was oversold because they thought I would not make my connection flight and that I was being put on another plane. The next day!

I had to line up in a very long line at AC Customer Service in T1 and was told by a floating AC representative that it may be possible to go on standby on a later 8:15 pm AC 33 flight to Vancouver. First she gave me my boarding pass for my rebooked flight.

A very nice man at the Business counter check-in at YYZ CDN departures helped me get on standby for the AC 33 flight. I LMU to PE on my first flight but was flying economy from YYZ to YVR because the LMU to Business was $700 (a little much).

When I arrived, my bags were not there. I was told that AC was not sure where my bags were, they didn't know where the could be?!?

I heard there may be recourse from the CTA of $400 for delays over 2 hours if it was a mechanical issue or bumped from an oversold flight? Is there any other recourse available? I don't have status but would think that the issue could have been handled better in the future. There were a lot of confused travellers.

Thanks!
