The passenger in the row in front of me was listening to a political speech on his phone at full volume with no headphones and it was disturbing all of the passengers around him for several rows. I asked 2 of the flight attendants to speak to this passenger but they only shrugged. It was obvious that they were afraid there might be conflict and would not say anything. I had to take it upon myself to tell the passenger that he needed to turn it off or wear headphones as it was disturbing everyone around him not wearing their own headphones. I was very disappointed in the United flight attendants.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

We had selected seats in the app that were a 2x2 format in the middle of the plane. Our seats when we got on the plane had been moved to the back rows in a 3x1 format. What’s the point of paying up for tickets that allow seat selection if the airline will just change them?

I flew basic economy, so it was what I expected. Crew was nice though, and flight was quick. Would recommend for flights under 6 hours, otherwise would upgrade to something with more leg room.

We were traveling as a family of 5 and they refused to seat us together. There were entire rows open, and my 13 year old daughter had to sit alone. Ridiculous!

Bad, they delayed my flight, lost my connection flight had to stay overnight for the next flight and missed a lot of important meetings. 1 day totally lost!

I missed my flight and they would let me on the plane

flights were on time, boarding was easy. maybe better snack selection, like mini kind bars?.

There were issues with the first segment but what really bothered me overall is that you rebooked me and put me in a seat away from my wife and then put her in another booking or boarding group. I don't like having to monitor every little thing you guys do in order to get what I paid for in the first place.

Calgary desperately needs a star alliance lounge in the transborder area for United.

Seat barely reclined. Boarding took forever. Flight attendants were not very friendly

Worst airlines. I will never fly this again. Please warn customers. They cancelled our first flight and then gave us flight vouchers that were declined.

Needs to be clearer about baggage allowances upon purchasing tickets

Very easy boarding. The on board snacks were not good.

We had a 44 minute layover ( ??? ) to change planes for our flight to SRQ. We landed at Concourse D, and the SRQ plane was located at Concourse B, as we were told in Toronto. We got to "B4" as directed by ( Delta Help ), in less than 10 minutes, only to see the flight we booked to leave at 2:28, was showing "DEPARTED". Back to Delta Help, got an extremely obnoxious and rude clerk who gave use two options, next flight leaving 5:20, on "B12", (STANDBY). or (CONFIRMED), leaving around 8:PM, not sure of the exact time because they took our seat request and gave us another boarding pass minus the exact time. We had been waiting hours for the 5:20 flight and at the very last minute a group appeared and were allowed to board. When the "standby" folks were summoned, several were allowed to board ahead of us, even though we were there much earlier. The clerk, who gave his name as Markus, a black man with a beard, was the most arrogant. rude and condescending individual in existence. When I asked him to repeat his name he said "what did it sound like?". Had I been thinking I would have answered to me it sounded like (markasshole) which is exactly what he was. When we originally got to that gate and asked for advice, he went on and on telling me he could only comment on the flight that was in progress, that ATL was a big airport, and treated us, both, in our 80"s like we were children unable to understand the process, and directly in my face in a loud voice, shouted exactly what we were already aware of. Not one ounce of consideration for our problem, of just trying to get home. When he called out the names of the remaining "standby" people, he left several go before us, even though we were there waiting hours earlier. He called out our names, John and Nubia, looked at us and shouted out that he only had ONE, and with a grin on his face, let another standby board, and told that person that she got the "lucky" last seat, still grinning, meaning we had to wait once again for the later flight. This obviously prejudiced and biased poor excuse of human beings needs to find a job he is better suited for, perhaps dog catcher or janitor, IMHO. This entire fiasco put us home more than 7 hours later than previously indicated on our original and paid for flight schedule. If Kayak continues to offer flights with different concourse locations and with only a 44 minute layover, they might also consider a more reasonable and reliable time frame for layover. It was a horrible experience and considering alternatives to this service is paramount.

Flight left on time. In flight entertainment options were good, but needed own device. Crew were polite.

Westjet has a terrible boarding crew. I had a zone 3 pass and my wife and kids had zone 9 as we purchased tickets separately. After scanning our boarding passes, the boarding Filipino lady rudely says that my family has zone 9 passes. I said I have 3 and wanted to board as a family and she started a rant that they have 9 and they were small kids to board with me. I told her that I am not going to separate family because of this and what she said didn’t make sense. It’s a shame to Westjet if they have such policy. It’s a shame to the WestJet employee to start this rant after the passes were scanned. Westjet has to train people to speak politely and not with rude demanding tone. If that’s Westjet policy, I will pick a different airline next time. Westjet is not the only one out there.

The flight itself was fine, but two of the ladies at the gate were extremely rude to a few of us in line. Their customer service really needs some help. I’ve always had good experiences with WestJet until these two ladies. They had the worst attitudes and really left a bad taste in my mouth after a good trip

Great assistance checking in & getting boarding pass in Vancouver. Flight delayed leaving MSP due to waiting to get 2 flight attendants.

Plane was tooo small, making cracking sound felt lime its breaking down. No tv, wifi doesn’t work. Only 2 restroom

Ok, a very small soda in a small glass was all that was served. Pitiful. Comfort seat was not, no legroom at all would not recommend comfort class, not worth the extra.

Air Canada did nothing for me when my flight got delayed and canceled and I had to spent the entire day in the airport and spend money on a hotel room, plus lose money on a car rental

I fly all the time for work & am used to seeing "XYZ flight facilitated by XYZ airlines" (or similar) and it's never been an issue. This flight from Edmonton to DFW through Denver was very early - 6 am, international, so at the airport by 3am. The flight was booked on Kayak through Air Canada and the actual flight was supposed to be on United. I didn't receive anything from Air Canada prior to the flight, other than to check in via United app when I tried to find my flight on Air Canada app. The day of, we were all on the plane at 5:45 am, when the pilot came out to let us know that the engine had been leaking for some time, and we were now going to have to deplane and wait for the mechanic to arrive and evaluate. So, we did. Why the flight wasn't cancelled at that point I don't know. After about an hour, sure enough - cancelled, however at that point, it's late already to try and get onto a flight out of Edmonton (YEG) on a weekend, esp. since post-COVID it doesn't seem that YEG has fully recovered in terms of flights and airline availability. Trying to get back to DFW took me the rest of the weekend from Sat am at 6 to Sunday pm - late, included renting a car on my own dime and driving to Calgary (YYC) which has more flight availability, as well as another night's hotel also on my own dime. I found some help on the United app - the chat personnel did try to help find some way home. When I called Air Canada after I couldn't get a flight through United - they were quite rude and short on the phone, letting me know that it was my problem (and United's) not theirs. Since Air Canada booked the ticket and took my money I would expect that if nothing else they would try to be of some help. I am so disappointed in Air Canada and their customer service, btw - my follow-up email to them for some type of resolution or acknowledgement was acknowledged by the system as having been received but as of this point - 5 days later - no response.

The plane was unusually hot and everyone was fanning themselves - very uncomfortable! My pull down tray was dirty and should have been cleaned. The flt attendants were pleasant.

I didn't actually get to take this flight. It was canceled and the automated system rerouted my party of four (including a minor and a person in a wheelchair) to three different airports. Since we had a three hour drive from Newark this was clearly unacceptable. For all of us to end up in Newark would have required waiting at least one day, probably longer.

Constant delays worked out in our favor but definitely extended our travel day

We paid $110 for more leg room. My traveling companion’s knees were right up against the seat in front. Where was more leg room. We feel ripped off. Food,,,there wasn’t any not even a bag of pretzels. As a result, there was very little service.

The crew and the flight was excellent. Captain kept us informed about weather and possibly of turbulence and I appreciated that! The only thing is they didn’t have tv monitors. Other than that, everything was great.

One of the flight attendants was very attentive to a couple traveling with a child under 1 one year old.

We were delayed. Only got 1 snack. Seats were comfortable in preferred seating.
