Air Canada cancelled my flight to Calgary on Mar. 26. I found out the day before when I checked in on line. No one notified me. I phone Air Canada and they said all the flights on Mar. 26 were full. They asked me to leave in the evening of Mar. 25 and I slept at the Calgary airport. Why did Expedia not notify me that my flight on Mar. 26 was cancelled? That's very poor service. I had to sleep at the Calgary airport! I think Expedia should compensate me for their miss-service and I had to suffer!
