I fly Air Canada from the west to Sudbury several times a year. The trip involves flying into Toronto and connecting there with a flight to Sudbury. In the past year, as many times as not, that flight has been cancelled and I have been rebooked as late as two days later! With some persistence, I have usually been able to reduce that wait, but today for example, I am spending eight hours waiting for the replacement flight. There are other flights before that, but I am at the end of the line in spite of having started this trip fourteen hours ago. Although it is AC policy as I understand it to provide a hotel for eight hour waits or longer, none is being offered and I got four different stories from the four employees I approached. With no clear indication of a possible earlier departure or their bringing in a larger plane to clear the backlog, I wound up sleeping on the floor. It seems AC does not place much importance on customer comfort or keep their staff informed. FAIL. Otherwise, when things go right AC does a good job.
