Flight was good, crew was excellent. No complaints at all

Delayed 3 times in a row for 4 hours total. Incrementally pushing back the flight claiming gate delays but they eventually changed the actual plane, due to technical issues. This strategy to avoid compensation to passengers is unprofessional.

The flight was full and good as could be expected. We arrived early which is always a good thing.

Plane was one hour late. Hardly any space for our carry-ons. Stressful to catch connections.

The delays were never ending and we were never properly informed as to why. 1st and 2nd delay were handled well, but by the time we received our 7th delay, and then subsequently asked to willingly get bumped, it turned into one of the worst flying situations of my life. I didn’t get home until 2am which is roughly 5 hours later than originally planned.

Plane seating was uncomfortable, very tight fitting for someone my height, did not recline and overall un enjoyable

No food, water, snacks.”beverages”. This was on Christmas Day. Upgrading cost $100, for what exactly?

Flight was 4 hours late. Landed at almost 1am instead of 9pm. No explanation given. The new seat configuration is the absolute worst. Uncomfortable seats, unreasonably warm. In flight "entertainment" is just wifi. We're expected to use our own streaming services. Terrible, terrible flight.

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

Very short flight. No food or entertainment required. Nice crew. Flight left late.

For my third flight in a row on AC 737 Max 8, it was stuffy and warm, especially mid-cabin, Business Class and rear cabin were better. Very uncomfortable 5 hour flight. Do all 737 Max 8 maybe have an HVAC software problem as well or just Air Canada?

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

The international flights (interior space) is ridiculously small. The aisle way is similar to a discount domestic shuttle. Same applies to the intercontinental flights. The luggage storage space is also incredibly small. The entire experience is rough on a traveler and you pay with your hide and body for not flying let’s say an American or Delta type airline.

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

It was a very small plane and was ok. No food or entertainment so there should be an option for NA.

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 liked the flight but the check in was horrendous. I have booked with you before but not ever had to pay extra for luggage, it was not clear on booking, I didn't know there was different categories of economy that meant different allowances. So was alarmed when we had to pay a further £120 at the check-in at a point of not changing.

I wish they gave the earphones earlier rather than when we are already in flight.
