I just think it’s unfortunate that Airlines have completely abandoned the idea of serving any kind of decent or even real food on flights, not even on a four hour flight!? Those days are gone, I guess.

I just think it’s unfortunate that Airlines have completely abandoned the idea of serving any kind of decent or even real food on flights, not even on a four hour flight!? Those days are gone, I guess.

The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

Hotter than Hades in August. Why, why do crews think that in the winter when we are already dressed for cold weather we need a cabin that is 82 degrees. Even the vents were blowing hot air.

Flight was delayed. De-icing took a while. When we landed had to wait for another plane to vacate our gate. Just an overall bad experience.

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

United have really come back. Airport and boarding process is clear and good, app and information also very good

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

Late FA meant slow boarding. WiFi did not work. I’m a medium plus sized passenger. The seatbelt was for the first time ever barely fitting. And we delayed on the tarmac 40 min

My husband and I had boarded the flight from Denver to Chicago, and one of the last passengers to get on the plane opened the overhead bin above my husband's seat and threw his bag out of the bin to make space for his own. He said, "Mine is bigger!" The flight attendant supported the new passenger. They didn't care that my husband has two artificial knees and must have the foot room in front of his seat to be able to fit his legs in -- and to be able to stand, much less walk, at the end of the flight. I have never seen this happen before, and it was a disaster.

Crew was helpful and cheerful especially when they had no refreshments to work with. The plane was never serviced and had nothing but limited water and coffee onboard. For the price point, a concern of services.

Flight was smooth, quick and felt safe. The 2 delays not happening would have been better but I guess that happens in the airline industry

Flight was canceled. I asked to be rerouted to OKC and then took an Uber.

AA did not allow to board a flight because my connecting flight from DFW had been canceled. I got on another flight to another city. No service on the plane and I did not use their entertainment system.

On time on a day with lots of weather cancellations on other flights. Thank you for getting me home during a winter storm!

Don't change gate multiple times make people run across the airport. Announce delays in a timely manner. Have maintenance crew ready. Don't delay and keep passengers on the plane for 3 hrs. on tarmac.

The plane was experiencing problems with the HVAC system, it was very cold in the front of the plane and very hot in the back.

We were upgraded to Business Class. So comfortable with great service and food options

The flight attendant use 1.5 hours to answer my call. My dirty food tray was unattended.

The attendants were kind and helpful. A sugar-free drink would have been very welcome.

Experience was good, the wifi hook up is somewhat tough

Great flight, great landing, nice staff. Our seats were a little cramped.

I will not be flying with westjet again. I was uncomfortable in my seat. The position made my back hurt so bad. My wife was able to fit the seatbelt around her with out an extension but was unable to put the tray table down or fit in the seat for that matter. Our bag was smashed and I spent two hours trying to fill out the application for a damaged bag before I gave up. The 80 photos I took would not work and nothing telling me the format to upload them as.. I made the mistake of unpacking the bag before taking photos so no claim for me. Next trip to Canada I will have to use air Canada.

Overall good experience. The wait for baggage at our destination was quite long, but other than that everything was good as expected

Airplane is too small. Crew, especially the flight attendant who looked after our area, was not at all friendly and a touch authoratative. She may have been the most gruff flight attendant i've come across in 40 years of business travel

I selected "carry-on" for a round trip on Kayak, but my return flight on WestJet did not include a carry-on and they would not allow me to add one. My only option was to add a "checked bag" which I had to wait for on the luggage carousel after landing. Not a good experience.

I was seated near a "stinky" person. That's not the fault of Westjet🙁😶‍🌫️

Do not fly on WestJet if you have a connection. It failed to integrate with my connecting Delta flight and I almost missed it.

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,

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

Air Canada’s problems are not staff related by and large, no. The problem is tiny jets between the U.S. and Canada - yes, believe it or not they are still “international” (just ask our own Mango Maniac in power in the U.S.). The little aisle is compounded by a design flaw of a “dog leg” starting at seat 12. Woe be unto you if you sit here as passengers and attendants do not have sufficient room to not hit you in the face with backpacks. One thing I will say very positively about Air Canada is you still provide pillows and blankets on transcontinental flights to all, not just the elites. Your tiny improperly designed jets are also a problem flying city to city within Canada also. One can only say you remind us of a “Jet Blue” or “Spirit” experience. Also your luggage space is downright Byzantine! We will endeavor to avoid you and use other U.S. carriers, albeit charging more.

Terrible canceled flight and lost my luggage. Flew me to Halifax. Tgat flight was delayed, had to spend night in airport chair.

My seat was not comfortable. Flight was smooth. Regretfully we had two delays before takeoff

They are very proactive and made our boarding easy and always notified us about any changes well in advance.

The staff could not have been any friendlier. Lots of usb ports on our aircraft.

It was crazy, boarded over a hour late from scheduled departure. Then when arrived in BNA issued with getting off the plane…over 1/2 hour. Not looking forward to flying Air Canada, ever again.

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.

Great flight. Only complaint is it took over an hour for my luggage to get to the carousel on the return to LAX That was irritating

1 hour late No hot drinks No restroom in the back of the plane

I had wonderful wheelchair assistance through the Montreal airport onto the flight. Air Canada was excellent in this both at the Fredericton airport and the Montreal one where an attendant helped us through customs as well as transport and baggage security.
