Had to deplane 2 x due to problems with plane. Delayed over 6 hours ans was given a $12 food credit which barely oaud for anything and limited to wear incoukd redeem.

Seats were not bad enough and uncomfortable good legroom in the emergency exit row we were in, but we were forbidden to hold my grandson on my lap for a little while, and the stewardess passed us saying it was against regulations which makes little or no sense when you’re 36,000 feet. The food snacks were really bad. Tasteless tasted like wallpaper, but we’re supposed to be protein bars, and the announcements were all completely incoherent because of the noise of the airplane and the lowness and crackly nature of the PA system.. this was disgraceful. No one in our party could understand a word of what the captain or the flight attendant were saying —not a word! The landing was a little hairy in a pretty stiff crosswind -we bounced before the plane stabilized on the runway

Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

NEVER MADE THE FLIGHT BECAUSE DELTA SAID THEY CAN NOT

Everything I mentioned earlier - the airbus was more comfortable indeed and the experience was further enhanced.

First class and monitors weren’t working for mine & my husbands. Eventually fixed, but quite annoyed as we bought first class. Also, No foot rests.

Overall it was not that bad! The delay on the second leg to Indianapolis , was really unexpected!!

The flight was oversold and they kept on announcing they were looking for a volunteer to give away their seat, but the announcement has to be louder and clear @ gate 88 and also must precise. Additionally, the departure time kept on changing. But overall it was fine since it was a short flight.

I received the two differed meals: chicken and pasta. I asked and I received. I am anti-wasting food!

The Code Share with Air Canada was not very streamlined. I had to check in at airport (not online) on the outbound and return flights

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

Very nice and clean plane. Transit time between flights was tight though

So far so good but food and entertainment are not available for this flight

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

The plane used to go to Chicago was a bit outdated and needed a refresh

The check-in and passport submission was complicated and repetitive, due to the poor communication between Air Canada and United. There should have been a single set of instructions and a single questionnaire that provided the data for both airlines.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Internet was not working for a bet . Hard to order food with our credit card because it was not in your system .

Service was okay except attendant over served alcohol to passenger and passenger got tipsy and made me uncomfortable

The window seat on the emergency row was too small. I had a different seat booked and they moved me. My seat remained open. It was very uncomfortable.

Please make more option. And be more precise on the type of food you giving. Diner and breakfast can be different

Flight delayed 3 hours, missed my connection in Atlanta. Instead of getting to Savannah at 6PM arrived after 10:00PM Middle seat, couldn't get isle or window, couldn't book my seats in advance, had to book at the gate. That's a 1st for me and I used to travel a lot

Agent checking me in was great. Plane was nice. Problem was with the handling of my fragile check in. They damaged my steel drum, waiting to hear back from them to see if they will take any responsibility. Think twice about travelling with something fragile, they don't seem to treat it any different than normal luggage

All was good except that the option to purchase wifi for texting throughout the flight didn't work. My partner and I both tried via the app, Chrome and Safari, we tried all payment options. Nothing worked. He was able to get ok blonde with he full coverage option, but it's nice to what we wanted or needed.

Don’t actually know how this flight would have been since we missed it.

I had planned to watch the Westjet entertainment for the entire flight however, because the seat mounted outlets in our row did not work.

Not a bad flight but our priority tagged luggage was the very last to come down the carousel.

Our recent flight from edmontown to kahalui was excellent. The service staff was very friendly, knowledgeable, funny and attentive. Thanks to all involved that made or travel such a pleasant experience and we hope to fly with west jet again soon

It was a good flight and we arrived on time, plane was clean.

The flight was fine. Long wait at security and for wheelchair. Got to gate about 5 minutes before boarding

It was our first time flying wit Air Canada. I found most everything very good, however, our flights leaving and returning were both delayed. And we were met with no place to de-board the plane and had to wait an additional 45 minutes on the plane after arrival. That was very disappointing. Also hefty fees both ways on what would normally be a carry on bag on any other airline.

Traveling from Montreal to SFO, after landing in SFO, there was no announcement about where to claim our luggages. Our gate was in Terminal 1, and went to the luggage claim area in T1, but couldn't find any information on the screen. Eventually, an airport agent told us that our luggages would arrive in Terminal 2 luggage claim area.

Great flights. Only criticism is when landed I. Montreal, wheelchair service has no signage or anyone letting you know where to go , just an older gentleman at the desk looking confused

This is a regional jet. As far as those go it was average. Again poor quality for an expensive seat. Not worth the upgrade

All went really well. Except that I was randomly chosen to be thoroughly checked!!

We were reluctant to travel with Air Canada after reading many bad reviews; however, we were more than satisfied with the experience flying from San Francisco to Montreal and back. Seats were comfortable (although on the return flight we had very little leg room) and the crew was friendly and competent. The entertainment was outstanding, with hundreds of choices, from movies to shows to comedy. Our luggage was delivered in a timely manner (a little slow in San Francisco) and we were sent tracking notices all along the way through the Air Canada app. I wouldn't hesitate to travel with Air Canada again.

it was by far the worst business class experience i've had. the food was awful, the staff was worthless and lazy, the drinks were warm, no blankets. dirty bathroom.

I could not even make this flight due to Air Canada delay on my first flight. I had to be booked with American Airlines and arrived 13 1/2 hours late. Terrible customer service.
