First a flight cancellation, we were informed about on the actual plane. Then we waited 6 exciting hours at the airport while another route was found.
Arriving in Europe late, we found our bags had not caught up with us. Next day they arrived with several items broken or destroyed.
After a lengthy claim filling out scads of paperwork, no compensation was ever offered. Air Canada official morons saying maybe I should have packed better.
Also, if you've ever taken one of their "air buses" on a short trip and survived, consider yourself fortunate.
Air Canada needs real competition to take away business they do not deserve. In such a wonderful country, such a horrible airline, should be very ashamed of themselves.
