FAQs - booking Colorado flights

  • Which airport is closest to Rocky Mountain National Park?

    Book a flight that lands at Denver Airport if you wish to visit Rocky Mountain National Park, as this is the closest airport to the major landmark and travel destination. Located near the town of Estes Park, in the north-central region of the state, the park is about 109 km from Denver Airport which should take about 1h 35min by car.

  • How can I visit the Dinosaur National Monument?

    Dinosaur National Monument is in the north-western part of Colorado state, near the border of neighbouring Utah. Delta Airlines offers flights from Vancouver Airport to Grand Junction Airport, which is the closest airport in Colorado. This flight route has a layover in Salt Lake City, so it makes sense to consider flying directly into Salt Lake City from Vancouver and driving the remaining distance from there.

    Located in Eagle County, Vail is west from Denver Airport and east from Grand Junction Airport, however both Denver Airport and Grand Junction Airport are within reach of the city. The driving distance from Denver is 2h 12min, while the driving distance from Grand Junction is 2h 14min, so you can book your flight into either airport when visiting Vail.

  • If I wish to visit Mesa Verde National Park, which airport should I fly into?

    Mesa Verde National Park is located in Montezuma County, in the southwestern part of the state of Colorado. Grand Junction Airport is the closest major airport to the park, however you will need to drive over 380 km from the airport. Another option is to fly into Denver Airport, and to then book a local connecting flight from Denver to Durango-La Plata County Airport (DRO), which is close to the park.

Terrible experience will never fly Delta again. Delayed flight with total disorganization and inept crew who wouldn’t communicate.

Terrible experience will never fly Delta again. Delayed flight with total disorganization and inept crew who wouldn’t communicate.

Will try never to fly Delta international again. Flight delayed and staff completely inept in dealing with it. Would not communicate, rude, completely disorganized. Once we reached Seoul the staff there had no idea what to do with us and led us around the airport from one pointless line to another. They were clearly not told how to manage the situation even though they had hours to make a plan. Never again.

They texted me my gate number and then they texted me again it’s now boarding but in different gate, and the gate was so far from the gate they texted me earlier. I have to run just to get to my flight. They always do that.

The crew and my luggage was still pretty good after a long flight. They take good care of the luggage.

On time departure and exceptional customer service during the entire flight.

The flight crews were extremely professional, helpful, and courteous. Departure and arrival times were accurate. No delay. I will use K airline again. Thanks

Not very comfortable seated in the back plane due to turbulence

We were seated at the back and that was very uncomfortable for me with the turbulence we experienced on our way to Chicago.

Everything about Korean air is great, hands down! Will always prefer this airline from other carriers.

Ford not that great the seat not to big for leg room like other airline

I always worry about flying budget airlines but I was impressed by Westjet. The checkin agent was terrific. Seated my husband & me together w/o us asking. TSA checkin was smooth & easy. Plane was clean & comfortable. Drink & snack was unexpected. I will fly with them again.

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.

Flight was canceled last minute and no re-booking was offered. Had to buy a same day flight from another carrier at double the price. I’ll never fly WestJet again.

Don’t actually know how this flight would have been since we missed it.

It was fine. I had a lot of trouble trying to buy a seat. The Westjet website charged me and then didn’t give me my seat. I ended up keeping the seat I was assigned and hope that the charges didn’t go through.. they didn’t. But this problem with the website (trying to purchase a seat at check in) has happened a few times before. But overall the flight was good.

Terrible! Delayed three times, landed at some corner of airport, walked in bitter cold night, took a bus, bad experience

My wife and I had an uncomfortable experience with your WestJet ticket counter rep at the WestJet Priority Member ticket counter at YYC (Calgary) on May 15, 2024. I not knowing this individual’s exact name, however, in order to easily identify her, she was one (of only two at the time) ticket counter reps at your Priority members ticket counter check-in, upon our arrival around 12:15 p.m. She was a Caucasian woman with blonde hair, and wore spectacles, approximate age being probably somewhere in her 30’s or 40’s. Background: After arriving in to the West Jet terminal in Calgary (YYC), I asked a terminal employee where the West Jet check-in ticket counter was. He told me, “Column 16”. My wife and I continuing to walk through the terminal, we finally arrived at the Column 16 area, i.e. this woman’s ticket counter area, which we discovered later was the Priority Member ticket counter. However, I was simply going by the directions given to me by the previous employee, i.e. “Walk to column 16.” Standing in her line (my wife and I being the only people in her line at the time), I tried to get her attention, and I then gestured to her, motioning to her as if to ask her if I should then possibly leave the waiting line in order to then proceed to walk up to her ticket counter. She never really motioned me to come forward. I sort of had to figure this out on my own, as my wife and I then finally decided to walk forward to her station. From this point on, after I arrived at her ticket counter, never once did she ever look me in the eye. She was always looking at her computer screen, or down at the ground, as she and I occasionally exchanged conversation with one another in order for me to be able to acquire my boarding passes from her. Shortly after she began servicing us, she commented that her work section is for Priority members only. Fair enough. I did not realize this at the time. Wishing to be polite, I then mentioned to her that, if I should, I could then walk over to the regular West Jet check-in ticket counter in order to complete the check-in process. She remained quiet, never responding to this goodwill gesture of mine. She continued to work in order to print out my boarding passes, and then finally handed them to me, never at all the entire time looking at me. I told her, “Thank you.” Never once did she respond. My wife and I then walked away. Even my wife commented to me afterward that this woman absolutely never looked at us. I cannot say that this attendant was outright rude. However, she certainly was not at all warm, congenial, nor friendly. Additionally, … After getting on the plane, we then discovered that she had needlessly assigned us seats in the very last row of the plane, these being the seats adjacent to the restroom back wall, thus, unfortunately not at all reclinable. I think that the row number of this last row of seats was 30. [However, I am not sure.] How strangely awkward that we were assigned these uncomfortable row of seats when in fact the row immediately ahead of us, i.e. I think that was row 29, had two vacancies, which could have otherwise easily seated my wife and me. That is, my wife and I could have easily been assigned these more comfortable seats, which would be reclinable, and then row 30 could have otherwise had instead our two vacancies. After our flight departed, and the fasten seatbelt sign was turned off, my wife and I had hoped to “jump seats”, that is, to leave row 30 and instead sit in row 29 to utilize the reclinable seats. However, another couple apparently had the same idea as us. That is, these other two people, for whatever reason, decided to leave their previously assigned seats, and instead, seat themselves in row 29. Thus, my wife and I were stuck with these miserably cramped row 30 seats for the entire 3.5 hour flight. To reiterate, the WestJet rep we originally encountered, knowledgeable of the plane lay-out as it appeared on her computer screen, could have easily assigned us the more comfortable row 29 seats, instead of the non-reclinable row 30 seats.

It was very, very cold extremely uncomfortable almost unbearable I was sitting at the front of the cabin

Was the longest flight I have ever taken to Orlando. Not Westjet’s fault necessarily. There was a traffic issue in Orlando. We sat in the airplane for about 2 hrs before leaving Calgary on a 5 hour flight was just a little long to be stuck in the plane. Once we arrived in Orlando we were stuck in traffic on the ground for another 30min. I guess maybe the flight could be delayed so boarding would have been later so we wouldn’t have to have the discomfort of being on the plane so long.

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.

Delays!!! Serious delays. I was told by a member of staff in LGA that I would miss my DEN to LAX flight connection, so I was put on a later flight. Due to delays I would have been able to have made my original flight, where I was sat in business class - seat 1A: I was put on my original flight but bumped from business - 1A to economy 33C. I want a refund for paying business class but only flying economy

Miserable. Active military on orders turned away from Lounge because not in uniform. This is completely contrary to United’s online lounge access policy. Sad that employees aren’t trained better. This is not the United Airlines my parents used to regularly fly with.

Too many canceled flights and kept my wife and I separated on alternate flights. We did not fly out of Denver. We paid a lot of money for the seats we wanted and now that money is gone and we did not sit together. That being said, the many agents were very friendly and did everything possible to help us.

3.5 hour delay known 12-16 hours before departure $15 meal vouchers which did not even cover cost of sandwich. Unable to reach agent for 1.5 hours, only then to be informed any rerouting to my destination would cost an additional $1000. Finally got rebooked on a 7.5 layover in Denver only to find out my original connecting flight was also delayed so I stood by and got on my original connection arriving only 3 hours late instead of 5 hours late. Overall journey was unnecessarily stressful and lenngthy!

When I got our tickets, my husband and I were easily able to get seats together (including a window seat). When we checked in at the airport all the seats were reset and we had to pick new ones, so we couldn’t sit together because there were only middle seats! Ugh that’s the worst. We were back so far we had to check our carry ons which was annoying because I bring an expensive camera that I don’t/cant check so I had to reorganize my items. Once we were seated on the plane we had to wait an hour to take off and they said there was some weather/air traffic in Denver but it was unclear. The lady I sat next to complained that our seats didn’t go back and we both got free complimentary snack boxes which were quite good. I wasn’t going to say anything about the seats, they were the typical uncomfortable kind. It would have been fine if the 2 hr flight hadn’t turned into 3 hrs. Not the best flight but also not the worst.

We love United Premium Plus! So comfortable without the cost of Polaris Club. The crew was so attentive and friendly!!

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Not worth the price of premium class ticket paid, felt more like steerage.

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

Flight was excellent in all aspects, - comfort , food, drinks, service, entertainment. Inspite of the computer glitch, the flight was on schedule and flawlessly. Thank you, air Canada.

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.

Flight was cancelled. Still stuck at airport. Going on 2 days straight, no sleep. Never fly Air Canada

Terrible. Flight in the morning was circling in air for 45 min due to weather then rerouted to a location further than the final destination to refuel. Sat on tarmac for almost 2 hrs to refuel. Flight was originally to land at 9:30am, we arrived at 2pm and then waited another 30 “for an agent”. Then afternoon return flight was delayed again 3 times for weather then cancelled. Auto rebooked was for the next evening! Just miserable.

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.

Would never fly lauffthabsa again. Seats were way too crowded together....very uncomfortable le

Tickets, paying for bags, and the lack of help by employees was the worst. It took almost 1.5 hours to get this done. The airplane, seating, and stewards were amazing!!! That part of the flight was one of the better flights I have taken.

Very good- my first flight with Airbus A380/800. Some of the food was not tasty , however. Everything else was excellent- the crew, the comfort, the process.

The airplane was as hot as a sauna upon boarding. I was dripping with sweat. Something needs to be done about that.

The airplane did not offer standard outlets so I was unable to work on my laptop. This is totally unacceptable for an international flight.

The smell of vomit from the previous flight was overwhelming for a 9 hour flight. There must be a chemical or product to kill the smell before the next flight boards??!!!

Overall good flight Aircraft is 787 hence seats are very narrow Asian veg food was better than expected International entertainment on screen had very limited choices

Check in and baggage drop was a disaster in both IAD and Frankfurt. It was unclear whether we were to go stand in the Lufthansa line or the United Airlines line. The supposed Service Desk in Frankfurt to get checked in with my 88-year father was chaotic, disorganized and they only offer seating to folks there to get a wheelchair after first making them stand for 30-45 minutes in a line, when seats are right there on the other side of their closed off area. Very frustrating on both ends in the experience.

Boarding process was hectic and unorganized. Delayed for hours, THEN delayed for weather.

No complains with the crew. But generally speaking food is awful, entertainment is not good either.
