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.

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

I liked absolutely NOTHING, Westjet is the worst airline in the world, they should be ashamed, they treated me like dirt, let's put it this way, I am truly pissed off. If anyone cares about my experience someone should call me so I can tell how bad my experience was, what a shame

If I wanted to leave on a Monday I would have booked to leave on Monday. Instead, thanks the west jet i spent another night in a hotel on my dime because they don’t even have a number you can call that works. It’s just says due to the high call volume we can’t take your call, that’s it. Our a Canadian airline industry needs an overhaul.

Fir premium economy passenger they didn't plan food properly ,only had 1 option available out of 3 on the menu as well as the drinks choice was limited

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.

I was never able to depart because of an IT outage, I could not get help through Delta’s website, app, or on the concourse. I eventually (after more than three hours in the airport) got rebooked with another airline the following day and Delta didn’t offer vouchers or any assistance with finding a hotel or getting to the hotel. I need to file a claim. Just an awful experience.

Over an hour late. Lousy flight attendant who was just going through the motions in every aspect of her job. The Dash 8 aircraft is super basic (no entertainment system, small seats, limited storage). Carry on luggage doesn’t fit in overhead bins.

Slow boarding process, tickets downgraded to Ultra Basic with no carry-on luggage, not enough space in overhead compartments

WiFi was not working. Zero entertainment. Did not receive a discount etc to make up for this.

Calgary WJET supervisor was the most professional, and diligent official who I have experienced personally to resolve our flight issues.

Our flight was delayed by almost 1 hour, and this negatively impacted our experience. Everything else was OK.

Flight was delayed, slow boarding,fully booked flight... No extra charge for beverages..

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.

Horrible airlines... did not compensate me for hotel or food even though my flight was delayed by more than 24 hours

My flight was delayed in Calgary and I missed my connecting flight to Cincinnati. I was rebooked on a flight the following day. I did not receive a food or lodging voucher.

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

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.

Everything was fine, would have been excellent if there was a tv for the passengers to make the trip go faster. Crew was great and the flight was smooth. Snacks and beverages are always a plus.

I called to put a stop to this ticket because it was fraudulent. Nobody stopped it. Then they sent me to Mastercard to fight it alone. Thanks (Sarc) to everyone who helped facilitate fraud and would not dare attempt to stop it.

Flight attendants should learn something about customer service. About how to deal with people Very disappointed This only happens only in Air Canada
