Find Cheap Flights from Chicago O'Hare Intl to Colorado

Pros: Nothing

Cons: We were delayed and received no update prior to arriving at the airport. Our gate was changed suddenly just before boarding time and then waited an additional 30 minutes to board with no information. We then sat on the plane for about 30 minutes, doors locked not moving, again no information. I did finally receive an email update that our flight was delayed after we'd boarded the plane. We are now landed in Denver and just sitting on the plane not moving pushing 40 minutes, what a suprise-with no information.

Cons: I haven't even left yet my flight has been delayed for 5 hours. No updates on flight status and all in all its been a stressful endeavor.

Cons: Terrible information and no service.

Pros: Fast boarding and that's the only good quality. No refreshments or snacks offered without a price tag included. Seats don't recline. Uncomfortable hard seats without any head rests for Support. Small tray tables that won't hold a laptop or drink.

Cons: It's been 45+ minutes after landing that we have been stuck on the runway unable to dock the plane due to some delays. How Terrible is it that the pilot gets on the radio to say he has no updates or much information to give! People are antsy, children crying and this delays all passengers with other accommodations. Seems like there's no communication or organization from Frontier at all!!'

Pros: No problems

Cons: A little behind

Cons: Seats. Too small not enough room to breathe

Pros: I like nothing about it and the customer service sucked

Cons: I hated everything about spirit I was waiting at my gate for about an hour until they announced all last minute that our gate had changed and the flight was boarding when I went over to the new gate there was no one there and the flight had left! 8 people experienced the same thing and missed their flight. The manager who came to save us was rude and did absolutely nothing about it. I had to find another flight on my own and pay extra and reschedule my car rental and hotel reservations. By far the worst experience I've had at the airport please don't be cheap and think you are saving with spirit, they are a headache and worst service ever!!

Cons: We were unable to catch this flight due to flight delay in Panama City. We are STILL at the airport in Fort Lauderdale waiting to get home.

Pros: Friendly crew.

Cons: Passengers are stowing personal items/multiple bags in the overhead bins. This is an ongoing problem that needs attention. Armrest protocol should be made explicit. My in-flight entertainment control was covered by the passenger next to me the entire flight.

Cons: How they canceled one of my flights just as I landed at my layover for that flight when I look back at Boston they had a direct flight ready for my destination. Very poor management I was stuck in Chicago with no money or food for hours then after they start boarding for my new flight they tell me that I may not be able to get on even with ticket in hand. It was a joke and very stressful

Pros: Everyone was really nice, and there was a decent amount of leg room etc.

Cons: I honestly can't say that I have any complaints about it. Thank you. :)

Pros: Delayed. Bagage mis-rerouted.

Cons: Be honest when bags are not routed correctly after assuring passenger twice that bags will be at the same airport they were re-routed too. Do not ask passengers for a bag delivery fee when the mistake was United's. Keep passengers informed of delayed flight and keep inconvenience to a minimum.

Cons: The flight attendants were very polite. Both of us are blind, and they told us the information we needed – how far away is the nearest exit row. Otherwise they treated us like everyone else!

Pros: Flight crew had a great sense of humor - they were extra friendly while boarding as well, made traveling with AA the best! Boarding was delayed due to previous flight but our pilot even managed to get us to Denver early! Wish I could have this crew everywhere I go!

Pros: The 2 flight attendants who continued to work this flight were amazing. The gate agent in Phoenix was also great.

Cons: 7 hour delay initially because of a mechanical problem, but massively exacerbated by an inability to find crew. Disappointing....

Pros: The crew was amazing - agreeing to work extra because it was Christmas eve and they wanted us all to get to our destinations for Christmas. They were very gracious and helpful.

Cons: We were over an hour late to leave. I understand the reason for the delay because of weather. What I was disappointed in is that the delay was not announced until our actual scheduled time to leave. It meant people coming to pick me up didn't get the change information in a timely manner.

Cons: I upgraded to Premium+ and it did not feel like an upgrade from a comfortability standpoint.

Pros: Nice short flight, crew was nice.

Pros: Crew

Pros: Crew

Pros: No delays everything on time

Pros: Although the plane was delayed, the staff did want they could to get us to our destination as quick as they could.

Cons: Delayed flight, which was fine but didn't update passengers as to why until we boarded plane. I didn't appreciate that as a customer. Questionable if I'll be a return customer in the future.

Pros: Everything is at an extra cost. From snacks to luggage to picking your seat.

Pros: Very comfortable! Fun crew! Coffee!

Cons: Check in

Pros: Nothing

How Terrible is it that the pilot gets on the radio to say he has no updates or much information to give! People are antsy, children crying and this delays all passengers with other accommodations. Seems like there's no communication or organization from Frontier at all!!'

Pros: Steamboat Springs, CO There were many CUBS fans on this flight! Good to leave rainy Chicago & arrive in dry Denver! Even though the plane was late, I was still able to catch my Alpine Taxi to Steamboat!

Cons: Seats. Too small not enough room to breathe

Cons: Flight was 2 hours late because we were waiting on a pilot to show up I used KIOSK to check in and husband and I wound up not sitting together...staff not able to help They charge for everything....even water.... Flight attendant on two occasions complained about his long day...boo hoo for him This was the flight from hell.....I am not sure I want to fly again....but, if I ever do...it won't be with Spirit

Pros: United payed for the room and 20 bucks for food.

Cons: Late. Missed the connection to Gillette and had to stay overnight.

Cons: When the guy in front of me reclined his seat, there was no leg room. Today, I literally have bruises on my knees....ridiculous '

Pros: Delayed. Bagage mis-rerouted.

Cons: Be honest when bags are not routed correctly after assuring passenger twice that bags will be at the same airport they were re-routed too. Do not ask passengers for a bag delivery fee when the mistake was United's. Keep passengers informed of delayed flight and keep inconvenience to a minimum.

Cons: Wish the seats were a bit more comfortable on frontier. And had to pay for carry ons. Will never ride frontier again.

Cons: Airline did not let us fly 45 min prior to the departing time, we were a party of 10 people; half of us checked in online and had payed baggage fees online but when ww got to the counter airline assosiate said we did not check in. Not only dod we loose our tickets but also the money for the fees we had already payed for. I had an uderstandong that the gates closed 10 min prior not 45. We had to fly becuase we had an emergency and this inconvinience just made our experince horrible. Defenetly dissapointed.

Pros: Absolutely nothing

Cons: Excessive carryon bag charges and delayed flight

Cons: My return flight over the holidays was booked for the incorrect day and time, even though my email confirmation had the correct days.

Pros: Nothing

Cons: 5-6 hour delay to board. delay leaving the terminal. All the gates were full when we landed, had to wait on the tarmac nearly an hour for a gate to open. Bags took forever. Frontier might be the most poorly managed company going right now.

Pros: I guess I should be happy that I am still alive. Other than not killing me, I can't say one good thing about Spirit.

Cons: They screwed up my reservation on the way over and charged me to correct it, then they cancelled my flight back. The next flight they offered was the next day - no offer of a hotel or anything.

Pros: As far as flights go it was pretty ez.

Cons: $50 carry on fee caught me off guard. I assumed it was 20 or 30...but that’s my fault for assuming.

Pros: No delays everything on time

Pros: Boarding was relatively quick

Cons: It took an hour from when we landed to get to baggae claim. Waited over half an hour from when we landed just for the plane to pull up to the gate, very annoying and a waste of time.

Cons: Had to check my bag because they ran out of overhead bin space.

Pros: Fine for a domestic flight. Normally, American Airlines offer a small snack to go with the drinks. But on this particular flight, they went the United way and offered nothing but drinks. Crew was pleasant enough during the flight, although they didn't greet half of the passengers entering or exiting the plane.

Cons: Flight was a little late taking off and therefore getting to Denver. But there was no announcement about it. There was one announcement from the captain, but it was so soft that I couldn't hear anything. Upon landing and arriving at the gate, we stood there for a while with no lights on and seatbelt sign on, but no explanation of what was going on. There was no welcome to Denver message either. Maybe their announcement system was down.

Cons: Full flight, but exceeded expectations

Pros: Professional, punctual good flight

Cons: Like on domestic flights limited service.

Cons: First flight of the day and there aren't enough floor assistants to address the sea of blinking red check-in kiosks. One poor soul is running around frantically trying to address all the check-in issues Pre-TSA doesn't start before our 5:15AM flight so after walking all the way down to the Pre-TSA checkpoint, we encountered a sign redirecting us back the normal tsa checkpoint which was overflowing with late check-in customers upset with the long kiosk check in delays

Cons: United is a horrible excuse for a company. 3 mechanical delays ultmately causing us to miss a wedding which was the reason for our trip. A 5 hour delay out and an overnight delay in the way home. We slept on the floor in the airport- one thing for us but disgusting to see United allowed this for elderly and families with toddlers and babies. The third mechanical delay occurred after we were finally bored and on the runway and they wouldn't let us deplane. Never have I been so terrified to fly.

Pros: I will try to avoid Ohare in the future. Long wait to take off. Had to RUN to make the connection. Again.

Pros: Friendly crew.

Cons: Passengers are stowing personal items/multiple bags in the overhead bins. This is an ongoing problem that needs attention. Armrest protocol should be made explicit. My in-flight entertainment control was covered by the passenger next to me the entire flight.

Cons: Seats are hard and our row was not allowed to recline. Late take off and late landing, plus we did not have a gate for 20+ minutes after landing. Crew acted like they wanted to be somewhere else.

Pros: a smooth ride. we left a half an hour late.

Cons: paying the carry on fee

Pros: The Busch league pretzels I didn't get because the flight got cancelled.

Cons: Not a fan of flights getting canceled with great weather on both sides and other Frontier lines taking off. Pay the extra for American; at least it will leave on time.

Pros: We got delayed because the plane broke down. Everyone else got $100 credit, but I didn't because I booked through Kayak. Could you please give me the credit?

Cons: Flight delayed 2 hours. Sat on the plane for an hour of that delay.

Pros: There is nothing I liked about this company their service or the flight

Cons: There is nothing I liked about this company their service or the flight on my foot way to Chicago they canceled my flight I had to book with somebody else and pay more for the ticket then on my way home they charge me $60 extra for a carry-on bag which is normally no charge

Pros: Flight wa direct and on time

Cons: Crowded!!! Seats too small- middle person spilling over into other seat soaces

Pros: Very comfortable! Fun crew! Coffee!

Pros: The crew was so friendly compared to other airlines, and the pilots seemed more skilled as well. Very smooth landings in spite of turbulence.

Pros: The crew was exceptionally polite and helpful!

Cons: The entertainment system at my wife's seat was broken - very disappointing.

Pros: I got to converse with the pilots before getting on board, and they were super awesome guys. Flight attendants were attentive and checked in frequently enough.

Pros: Boarding was fairly quick and on time. Transfer in Phoenix was no problem. Luggage arrived OK.

Cons: Seating is too small and too close to next rows. Unhappy with having to pay for seat assignments and checked bag while watching gate agents refuse to enforce overhead bag size limits.

Cons: This flight was canceled because my initial flight was canceled by united and then I could not take the rebooked flight so I could not keep the seats together with the travellers I was with and then was placed in the back of the plane. When my flight was canceled initially no one informed me that my return ticket would be canceled which I specifically asked about. I hope never to fly united again. The day to day staff at ohare and on flight were good and courteous.

Pros: Delayed. Bagage mis-rerouted.

Cons: Be honest when bags are not routed correctly after assuring passenger twice that bags will be at the same airport they were re-routed too. Do not ask passengers for a bag delivery fee when the mistake was United's. Keep passengers informed of delayed flight and keep inconvenience to a minimum.

Cons: I want to clarify that I boough tiquests with Lufthansa not with United... and I had to travel United most of the time to Africa and Bach to the USA... united socks terrible ... bad food and old plain to cross the Atlantic... besides the service and the bad actitude of the employees... when I travel international I want only Lufthansa. So, kayak you tricked me ....horribly!

Cons: internet & movies intermittently worked

Cons: Lost my baggage after 2 hour delay. No attempt by airline to assist the customer or compensate the customer after clear mishandling by the airline.

Pros: The price of the flight

Cons: The fact that frontier will not transfer checked bags to a different airline. If at all possible, I will never fly this airline again

Pros: What I liked? That the flight ended and I could get off the plane.

Cons: They charged to pick seats. They charged to carry on a bag. They charged for any drinks. The seats had NO padding. The seats didn't recline. The gate at O'Hare was dark and dirty. The travelers in my flight would have scared the residents of Mos Eisley.

Pros: Overall quickness and friendliness of staff.

Cons: No free food.

Pros: Although the plane was delayed, the staff did want they could to get us to our destination as quick as they could.

Cons: Delayed flight, which was fine but didn't update passengers as to why until we boarded plane. I didn't appreciate that as a customer. Questionable if I'll be a return customer in the future.

Pros: In general everything was pretty good.

Cons: Flight was 1 hour delayed and Boarding crew was sending us from one gate to another. That was so unprofessional.

Cons: Nothing about this flight was relaxing or welcoming! The staff was extremely rude. To check a bag in its way over priced. I asked for a cup of water in which I was told it would be three dollars for a bottle of water . WATER! The seats on the plane were extrmemly uncomfortable. Overall I would never recommend nor fly spirit again.

Cons: You have to pay for food and drink which is extremely expensive if you don't bring something with you on the plane
