My flight was cancelled and I was left to figure out where to find a hotel, something to eat and how to get a new flight at 11:30pm. Wasted a day. Thanks, Air Canada!

My flight was cancelled and I was left to figure out where to find a hotel, something to eat and how to get a new flight at 11:30pm. Wasted a day. Thanks, Air Canada!

flight was delayed 6 hours for weather, then cancelled because of the crash in toronto, but none of the links to cancel or rebook my flights are working

They kept changing the gate (6 times in 30 minutes) and then left us on the plane for 4 hours before departure. Likely was the storm, which is understandable, but the lack of communication and the e constant running between gates at opposite ends of the airport really threw me and my friend for a loop.

Legitimately everything about this flight was awful, was also so delayed I never want to use air Canada again

Terrible all around. Flight was late and airplane was very uncomfortable. The crew were unhelpful and hid in the back. Did zero work. No entertainment.

I like the free beer and wine but not the delays to the departure time.

Never again flying economy on Rouge!!! Literally like sardines!!! Will try to change to better seats 3 seat arrangement only so so if traveling with family. Who wants to squished to stranger!!😖 Can’t say enough bad about this!!!

I booked and paid extra for exit door seats also pre paid for my luggage air Canada changed plains and I never got what I paid for and they made me pay for luggage again they also did this to my wife. They are the most unorganized company I have ever dealt with. I am sure I will never see the extra money I paid for the seats or the recharge for the luggage. They are subsidized by the taxpayers and don’t give a dam just a horrible way to do business

Overall the experience was excellent. Plane was clean but more importantly quiet. Recently, I’ve noticed that Airbus planes seem quieter than their Boeing counterparts. I definitely prefer flying in an Airbus plane.

Delay after delay.......they are awful Delayed because of cold wx really!!!!! We live in Canada
