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.

Food choices were very limited. Taste of the dishes was average.

I liked all the informational texts. I always knew where to go and when .

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.

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

First flight out in the morning is often the best chance of running on time. Not in this case, which unfortunately is now what passengers can expect as what is common. - If you are late for a flight, too bad for you. - If West Jet is late, too bad for you. - Bags don't make it? Too bad for you. - Flight change by 1+ days, too bad for you Prices continue to increase, while customer service nosedives. This is backwards and in any other develop country would be considered unacceptable - except for Canada. Too bad for us.

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.

Not much....we did not get the complimentary beverages promised in our ticket. My partner and I did not have the window seats promised. We didnt get to sit together.....

It was great. Although when I got my luggage it was broken.

The only issues I have are the seats are very small and so is the overhead storage. You should mention that while booking flights. I had plenty of knee room but I am wider than my seat, and I am not fat at all. The Mitsubishi 900 models need to be upgraded to western size people. I do not know how a 300 pound woman fit into those seats. I had to continuously lean away from the aisle to keep people and flight crew from bumping into my shoulder. 3 hour flight so no entertainment or food, just snacks and a drink, which was no big deal. The buttery/garlic pretzels were pretty tasty.

I liked not paying for carry on and the compensation my husband and I received from the airline for overbooking our flight. The staff was very friendly and helpful.

It was a short flight and for that reason the flight was acceptable.

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.
