Airline reviews

The plane was delayed substantially due to a mechanical problem, that being said, the airline was very fair with providing a meal coupon for us. I would rather arrive late on a mechanically sound plane than the alternative. The food served in the plane was just awful, however and I recommend a new catering company.

Very bed experience never want to travel air canada anymore

I liked all of it, and excited to do it again~* Thank you, and Much LoVe and Respect, CHRiS aka KRYSTOE 👣🎵 http://www.chrisrousemusic.bandcamp.com Google = chrisrousemusic and/or KRYSTOE

I travelled in Business class for the first time and wish I could do that again.

It was good, seating was a little tight apart from that all was well.

I waiting for 2 hrs to retrieve my luggage. Didn't get home till 3am.

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

Flight attendant told passenger to move my bag in order to accommodate his not allowed roller bag then proceeded to crush my bag. When I complained flight attendant said roller bags take priority. Yet this flight was on Rouge which only allows one personal carry on. But not enforced. So I was penalized for paying to check my roller bag.

My flights were all either late or canceled. It was stressful and a waste of my time. This is the third flight in a row with Air Canada that has been a scheduling mess. Not appreciated.

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.
