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

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

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

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

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

There was a man who was very rude at boarding. On the other hand personal bag measuring box is too small compared to USA airlines,

While I appreciated the food (it was unexpected), it was interruptive for sleeping. We paid extra for reserved seats, but when we checked in they gave us different seats. I had to call WestJet arounf 11:30pm the night before our flight to get this fixed. We were give seats in the emengency row to resolve the issue.

A little better seat cushions would be appreciated. Crews were all good.

The process and flight were both smooth and trouble free

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

my carry-on bag was delayed and I did not receive it until the day of my return at the airport. This delay caused me significant inconvenience, as I did not have access to my personal belongings for the duration of my trip. I had expected to rely on my carry-on items, and being without them negatively impacted my travel experience.

Technology issues at the bag-check counter caused a delay, and we were unable to check out our bags, ultimately missing our flight. They offered no assistance other than telling us to book another flight out of Calgary. We arrived with plenty of time; if there hadn't been an issue with the kiosk and the length of the lines due to the technical issues, we could have made it home.

Worst check in and bag drop off experience. Staff were incredibly rude given that it’s the WestJet system that is faulty.

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

We were happy with our experience. The price for tickets was much less than Delta and we actually took off and landed a little ahead of scheduled times.

I was very excited when we were to arrive 19 mins early . However that did not last long since there was no available gate and sat there waiting almost a hour.

Seats horribly uncomfortable. Air nozzles didn't work so very overheated.

Every person and every experience with Air Canada was excellent. All customer service was outstanding and done pleasantly. The notifications through their App were timely and informative. This airline shines. All other airlines should take training from them.

Better than usual. We’ve flown air Canada for years at least once or twice a year and used it to bring our Canadian American son back and forth from USA and Canada and Europe and we have had MANY bad experiences with late flights, missed connections, boarding issues, for almost 10 years. Just lots of bad experiences. This one wasn’t bad at all. It’s simply what we expected. Even though the first flight this time was 45 min late in leaving due to a maintenance issue, that didn’t mess us up. But all else was fine so we were pleased.

It was just ok, after a weather delay and had to take 3 planes in one day I asked for another cookie and she said no only one per passenger, found that a bit pity after spending my whole day in airports and planes

Boarding was challenging as we had to use the stairs from the tarmac. Stairs are okay but a roller bag makes it challenging.

All good, but plane outdated, seat uncomfortable, food that we had was 4 out of 10. Crew was great!

Lack of crew staffs to handle emergency medical situations that ending no meal served and only hot water and bag of pretzels served for business class!

Very Poor Even with the disruptions our flight was delayed twice then eventually cancelled. Subsequently we to this date have lost 3 days of our vacation. The situation still remains unresolved

The app and the information given at the counter did not match
