Flights from Calgary to Denver: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew the route from Calgary to Denver 
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.

Not as good as expected Air Can needs to improve totally rated on internet as worst

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.

It was 4 hours late. Almost missed my connecting flight no food or drinks on connecting flight. Overall terrible experience

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

Experience was good. Was surprised they didn’t offer a complimentary meal on a 5 hour flight.

Too squished in seats. I'm 110 lbs and 5'6....can't imagine being any bigger and flying

The flight attendants were great, but not much room while sitting and it would be nice to get free movies.

Original flight canceled and communicated poorly. A series of gate changes , delays and plane changes followed. Even after the entire flight boarded there was another plane changes followed. Food vouchers provided to my travel companion but not to me despite being on the same reservation. No in flight entertainment. The entire experience was terrible although the flight crew were great.

It was great being a direct flight from Calgary to Tokyo. No transfer to worry about.

Very old planes. Seats were not comfortable. Air was not on during the flight leading to incredibly stuffy conditions.

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.

I was overcharged either by United or sister airline Air Canada. It's exhausting dealing with companies nowadays that irresponsibly abuse access to credit/debit cards.

The flight attendants that assisted me were exceptionally nice, kind and helpful

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.
