Find Cheap Flights from Denver to Chicago O'Hare Intl (DEN - ORD)

Pros: Planes are old as dirt. Flight attendants were unfriendly and unaccommodating and finally, there was a 2.5 hour world wide data transfer systems failure on the last leg of my trip. Have a 12 hour day of surgery followed by appointments. Thank you United. Your airline is a joke and I'm ditching your stupid mileage credit card. I'd rather purchase magazines with my miles than fly with you ever again.

Cons: Absolutely nothing.

Pros: baggage crew was awesome on this trip. my skis and bags were awaiting in the claim area before I completed the walk from the plane to the baggage area

Cons: Delayed over an hour Changed gates after our initial flight time

Cons: Boarded and left late for many to miss connections. No real help to get to new connection both on plane and off.

Cons: We landed and had to stay in the plane at the gate for over 30 min. They said they couldn't get the jet way to work. Really stunk, because was a late flight.

Pros: They left me alone.

Cons: Fold down tables are tiny

Cons: Late departure

Pros: It was a short flight.

Cons: Uncomfortable seating. No free soda/snack. Expensive soda.

Pros: Smooth flight

Cons: Nothoing

Pros: The flight was the cheapest we could find.

Cons: Spirit doesn't seem to know how to do anything on time. They charge you an arm and a leg for even a carry on. Not worth the mediocre crew, uncomfortable seats, and long wait times. Every time I fly Spirit I say it will be my last, but this time I really mean it.

Pros: My trip was fine, nothing outstanding, nothing horrible.

Cons: The flight was 2 hours late taking off. That is a bummer especially since you have to be at the airport 2 hours early. Spirit did extend a $50 travel voucher towards a future trip but I would have rather arrived at my destination on time. Luggage fees are pricey...$50 each way for a checked bag. OUCH!

Cons: There was a power outage and the Spirit representative told everyone that the plane wouldn’t leave anyone behind. Once we got through security at to the gate they said the plane left 2 minutes before. No announcement was made. I could’ve saved time checking in online but the server went down (seemed unrelated) and the site is incredibly confusing. Its hard to describe but all the employees seem really inexperienced and it’s hard to get good information. So unreliable

Cons: The crew knew multiple people on the Hayden to Denver flights had very limited wait time to get from plane to terminal, but took forever in delivering our luggage for plane side pick up. When I asked the lady who came by to let us know of our gates, she pretty much told me, 'good luck'. I picked up my bag with 10 mins to spare to run from gate 86? to 24. I think more should have been done to accommodate. To be fair, the other lady who came by to let us know of our gates, offered to call my terminal and let them know I was on the way

Cons: Very late.

Pros: On time for once

Cons: Cost of the flights + baggage

Cons: The landing was terrible. I guess everyone is allowed a “opps”

Pros: Good boarding process

Cons: A crew member had a very loud, extremely personal conversation for the entire duration of an early morning flight. She made eye contact so I knew she knew what she was doing

Pros: The crew was nice and they were apologetic. I know it wasn't their fault. They gave status updates every 15 minutes but in the end they were generally 'wrong'. Some people were angry about this but it wasn't their fault. How could it be? They were just repeating what they were told. It's not their fault that their organizers told them incorrect stuff. I sympathized with them more than I usually would because some passengers were such jerks to them. I appreciate that they were keeping us in the loop. We basically knew as much as they knew. It made me feel like we were all in this bad situation together, which we were. They wanted to get home, too. That was the right way to handle this. The actual flight was uneventful. Plane was clean. Seats were about as comfortable as you would expect for the price.

Cons: Where to begin. It was delayed 1.5 hours, then we boarded, waited maybe 30 minutes, then we UNBOARDED because they needed a new plane, then it was delayed AGAIN. When we finally landed in Chicago we were about 5 hours behind schedule. I feel bad for the crew because they were left dealing with angry passengers, I know it wasn't their fault. Just poor corporate planning. In addition I did have a truly mind boggling experience with an employee. We were lined up for our first boarding, in a huge line, having waited for 1.5 hours, and suddenly a woman with multiple bags cut in line. I said "Excuse me ma'am but there IS a line" and she smiled and said "Oh, sorry, I'm an employee". I apologized and she cut everyone and boarded. That's when I realized that she was NOT WORKING THE FLIGHT. She was just using her privilege to cut in line. She cut in front and saved maybe 5 minutes. I mean, why bother. Why bother pissing off paying customers to save 5 minutes. People around me were so angry. Then she got on the flight and held everything up because she needed to load her 4 pieces of luggage into the overhead bin, taking up an entire bin. Flight crew actually moved people's bags to accommodate her. And one of her bags was a full sized suitcase that would never have been allowed if she wasn't an employee. Simply ridiculous, the only thing saving her was that there were open seats. She was not taking a seat from a paying customer. I would say that I wouldn't fly Frontier again but honestly all of the companies suck so I don't know who to pick. Every airline has some story or another of crappy customer service. I wish the barrier for entry wasn't so high so that competitors could swoop in....as much as I dislike the Elon Musk's of the world it would be great if some billionaire swooped in with their money and made an airline that actually worked.

Cons: Flight very rough and crying baby and general just did not feel well and was upset flight was delayed and then got home much later and had to be awake early in the morning for an appointment.

Pros: Nice staff

Cons: Delays without frequent or informative updates.

Cons: The charge for bags is extremely high. The cost of a soda on the plane is $3.

Pros: The people were friendly and you can't beat the price.

Cons: The trip out was late, but that was because of weather, so no biggie. But on the return trip, we sat on the tarmac for over an hour because of "boarding gate problems". There was a loud beeping noise for the entire hour we waited and only one announcement was made to explain the situation. At some point we were finally allowed to exit the plane onto the runway (not the boarding platform).

Pros: Nothing

Cons: The seating, the company, the crew on the plane was very rude. Basically everything about the flight was terrible. I'll never spend money on this horrible company again.

Pros: Prize Time

Cons: Boarding by zones causes passengers to have to stand longer while waiting to board, inconveniences them by having passengers seated in window and middle seats often arrive after the passenger in the aisle seat, and slows down the entire process because passengers settling into the front part of the plane frequently board and stow luggage while those seated in the back queue up behind them. Compared to boarding by row, the entire process is now one lengthy mess.

Pros: On time for once

Cons: Cost of the flights + baggage

Pros: Staff was very friendly.

Cons: I only had 2 nights in chicago and one was completely ruined as we got in so late that the event we were supposed to attend was already finished. We also were sitting for a long time and it was very uncomfortable while waiting to take off. We didn't get any beverages after sitting for a long time and finally did once we were in the air which was 2 hours later.

Pros: Cost

Cons: Last row

Pros: Smooth flight and pilot a spoke to us a couple times

Cons: Stewardess over intercom had poor diction.

Pros: We got there ahead of schedule

Pros: 5 hour delay for "wind"? United on time or less than 1 hour delays, Continental on time or less than 1 hour delays. Frontier-5 hour delay! No food vouchers no explaination, no nothing.

Pros: Low cost

Cons: They make you pay for everything. Even peanuts. No entertainment.

Pros: NOTHING

Cons: Terrible customer service. Delayed my flight 3.5 hours because they didn't have a crew. Slow to send updates. Had to pay an absorbent fare on another airling to make my connection. I wouldn't fly Spirit if they gave flights away.

Pros: The Crew

Cons: The Flight was delayed 7 hours

Cons: Flight was cancelled without explanation. Found out at the airport instead of text, email, or call beforehand.

Pros: The flight,the landing and the crew jokes.

Pros: Planes are old as dirt. Flight attendants were unfriendly and unaccommodating and finally, there was a 2.5 hour world wide data transfer systems failure on the last leg of my trip. Have a 12 hour day of surgery followed by appointments. Thank you United. Your airline is a joke and I'm ditching your stupid mileage credit card. I'd rather purchase magazines with my miles than fly with you ever again.

Cons: Absolutely nothing.

Pros: I liked the flight attendants that they were courteous and helpful

Cons: I am a fearful flyer and that is putting it mildly. I didn't like that the pilot didn't introduce himself and talk to us about the flight.

Pros: It was fine

Pros: The staff was friendly and the boarding was orderly

Cons: The economy seats were so squished and everything from movies to food (other than Chex mix) is an additional fee. I'm a small person and still felt like the personal space and leg room was way smaller than it should be. I had to pay $8 to watch cable bc otherwise you just have to look at a screen with ads on it the whole flight. I used to love united. Now I feel like it just sneaks in extra charges like all of the cheap airlines. Not going out of my way to look for united anymore.

Pros: I enjoyed that I had an aisle seat when I chose a random seat instead of paying for one. The crew seemed nice, a little overwhelmed but I had limited interactions with them. Boarding was fine and I was relatively comfortable on the plane.

Cons: I did not like that Frontier allowed for multiple people on the plane to yell and scream about the flight being delayed and how terrible their service was using lewd, degrading language that I felt unconfortable listening to after spending 6+ hours traveling before I even got on the plane! As a holiday traveler I am aware that there are delays and things are congested, maybe I'm the only one. I did not enjoy that I had to be subjected to that while sitting on an airplane that landed 45 minutes before even reaching gate. This continued on to the baggage claim section for another 45 minutes until finally I told the guys to shut up! The 2 men should have had security called on them or taken to another room to air their grievances instead of subjecting the rest of us to their tirade. I was extremely uncomfortable and disappointed in the way Frontier airlines at O'Hare handles disgruntled passengers and will most likely not fly Frontier again despite having a relatively enjoyable flight.

Pros: It was a short flight.

Cons: Uncomfortable seating. No free soda/snack. Expensive soda.

Cons: Some passangers were not charges for carry on bags but I was charged $45 for a small carry on bag.

Pros: The crew was nice and they were apologetic. I know it wasn't their fault. They gave status updates every 15 minutes but in the end they were generally 'wrong'. Some people were angry about this but it wasn't their fault. How could it be? They were just repeating what they were told. It's not their fault that their organizers told them incorrect stuff.

Pros: The crew were super nice!

Cons: Weather delays! Seemed like all of the other airlines cancelled flight and/or were flying and my flight got pushed back our after hour after from leaving at 8:05 til 1:30. Would have been since to just come to the airport later vs having to wait there

Cons: Cramped seating, limited overhead bin space, mediocre experience. Next time I’ll spend the extra money and fly Delta.

Pros: The pilot was great and excellent landing for a safe return home!

Pros: Ticket agent was very helpful when I misplaced my boarding pass.

Cons: Arrived safely which I’m grateful for but we arrived later then originally scheduled (45 minutes).

Cons: No wifi

Pros: Crew was good. As always not enough leg room if you are taller. Resent having to pay extra for more leg room.

Pros: The seat was great, I wish all seats on the plane were that comfortable

Cons: Nothing, everyone was great

Pros: This was a Delta codeshare on KLM metal. We left on time and arrived early. The crew was very professional. The bathrooms were very clean.

Cons: The seat in Economy Comfort was awful. Not enough padding and no place to put my feet because of a very large entertainment control box on the floor.

Pros: Airport person with wheelchair at Denver was extremely helpful getting a disabled co-travelor from gate b85 to gate b28 in record time to catch the flight to Chicago. A BIG Thank You to the agent in charge of boarding for getting the three of us sitting together.

Cons: The direct tv screen couldn’t be shutoff. With a plan as big as a 757 there should be a beverage cart per section of the aircraft otherwise passengers at the far end are wondering why they’re being left out.

Pros: No the crew were not very friendly at all. I was not greeted with a smile at all. My seating was horrible, I unfortunately was seated in the last row, beside the washroom. My seat would not recline. I will never locate my seat at the rear again, total claustrophobia.

Cons: do not take the rear seat in a small airplane ever.

Pros: On time for once

Cons: Cost of the flights + baggage

Cons: Old huge plane. Sat in back. Awful. Didnt move for what seemed like half an hour or more before we even started moving toward runway. Then did the same thing once we landed. Chlosterphobic and awful.

Pros: Nothing

Cons: Everything - best to avoid this airline unless you like poor service, paying for baggage, carry-ons, even for the seat you just purchased. You can't reserve a seat without paying extra, regardless of the seat location. Once you pay all the additional fees this low cost airline ends up being a premium with poor services. Baggage drop is silly, everyone has a problem and the line to "drop" off is ridiculous. And, expect to be delayed for no particular reason other than Frontier flight operations

Pros: Nothing

Cons: Flight staff was rude. Especially the older blonde lady. Seems like she hates her job and I heard her cuss at a passenger and tell a child to shut up

Cons: Late departure

Pros: Low cost

Cons: They make you pay for everything. Even peanuts. No entertainment.
