Verified travelerFlew with United AirlinesYYC-DENAug 2024
Denver International is a really nice airport, but it should be for a hub! A lot of stuff is actually open until 10:30 or 11pm, so that’s nice. Pretty good place to do an overnight layover too…just make sure to get some snacks in case you can’t sleep.
VictoriaFlew with United AirlinesYYC-DENMar 2024
A tip I have is if you’re in a 4/5 boarding class you might want to check your bag ! There’s not enough room for everyone’s carryon above if it’s a full flight.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

I was at the back of the plane with earphones, and I could still hear the chatty flight attendants; I wasn't able to sleep at all.

Flight was 3 1/2 hour delayed with no credit or meal vouchers

United airlines was top for my last trip in every way

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

Horrible; seating was atrocious - inadequate leg room and seat width tight even for a small individual. Profits shouldn’t be everything!

Liked that we left on time for each flight. Snacks not the best, but we're okay.

It was fine. The flight attendant appeared to be in a bad mood but everything was fine.

Traveling on two legs the food was identical and not very good

We are experiencing more delays with westjet than other companies. West jet used to be our favorite airline.

Excellent and a surprise as I had never heard of it before.

Was a short flight, not good or bad. Extremely cramped and I'm only 6feet 1inches. 295lbs.

Terrible experience at the gate. Charged for carry on luggage despite them meeting the requirements for sizing.

Check in agent was good, stewardess was unfriendly and certainly did not have the care of the passengers in mind Spent the whole time on her phone

we were upgraded to business class, not sure why, so the flight exceeded our expectations. Perhaps this was because the flight Cancun to Calgary was a nightmare , not even guaranteed a seat upon checkin at the airport.

Average at best. Typical of WestJet these days. Crew far from friendly.

It was fine for a low cost trip. No entertainment and poor food offer. The sits were ok. It was on time.

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

The seats really could do with some extra padding. The staff member who checked me in at Calgary was amazing. Friendly and lovely.

I was very good. Service was great. Seating selection was not too good.

Very good. But seat selection was not good. We were put on different rows. Would have been nicer to sit besides each other as a couple.

The trip from booking to execution was great! The plane from YVR to YYC had LCD panels for entertainment which was great, but the return flight from YYC to YVR did not have them. Oh well--it was a short flight. Food was a pretty minor "token" snack, but hey--it was a short flight. It could have been skipped entirely and I would have rated the flight well.

They were so kind and helpful and they even brought an item of mine that I forgot on the plane!!

Terrible. Frequent last minute flight cancellations with terrible rebooking options!

United did not permit online check-in from home as document scans were not getting uploaded. This should be fixed their app

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.
