My flight got delayed 5 times and then got cancelled eventually, I had to get a hotel and uber and pay for food for an extra night without any plans. It was a horrible experience, instead of Air Canada, I was flying with United .

My flight got delayed 5 times and then got cancelled eventually, I had to get a hotel and uber and pay for food for an extra night without any plans. It was a horrible experience, instead of Air Canada, I was flying with United .

I had a nice flight with free wifi. So I was able to message family members and stream music during my flight, which made the trip go by fast. I also enjoyed flying on there Airbus A220. The plane looked very new and it also got up to speed fast down the runway and didn't need much runway to get airborne.

They lost my checked in luggage, why do I pay for my cargo not arriving at the same destination as me?

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

Poor planning meant the plane was delayed an hour, then a thunder storm started and the ground staff couldn't work. Eventual arrival in Santiago was 3 hours late resulting in missed connections and the need to buy new tickets.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

All was fine. Weather was a bit stormy, but nothing kayak can do about that! 😊

I paid for a comfort class seat and was seated in economy.

The take off was delayed as we were told that the baggages had to be rearranged to balance the weight. I only took a carry-on and a personal item, but the overhead bin was extremely small, even a normal size carryon can’t fit it, so they had to check it in for free. The seat was really tight and no entertainment at all.

Once again our Air Canada flight was delayed! I'm hopeful competition arrives with other airlines soon and maybe they will make a better effort to be on time!
