Find Cheap Flights from Denver to Chicago

Pros: Crew was friendly

Pros: Boarding was quick and efficient.

Cons: Seats were kind of uncomfortable.

Pros: The seat. Big and comfy upgrade

Cons: The cost of the big comfy seats

Cons: Flight was delayed repeatedlly throughout the day with little to no notice at times. Original departure time was 1:55pm and was pushed out until about 2 - 3 times for “mechanical issues” until 8:20pm. By 8:10pm there was still no plane and no additional updates; we didn’t board until 8:30 and didn’t takeoff until 9:46pm

Cons: Very long taxi combined with late departure = very late arrival

Cons: Seating is horrible, no leg room, no reclining seats. Allow too much carry on.

Cons: Terrible experience. 2 hour delay and then delay getting off plane due to mechanical isssues on the jet bridge. Terrible experience.

Cons: Got to airport an hour early. Got to check bag lady with 45 min before flight. They made me pay $15 more and carry my bag thru airport or I couldn't board the flight. Very bad experience

Cons: Wouldn't let us change or cancel our flight a couple days in advance, even for a death in the family.

Pros: Paying $35 to “upgrade” to basically any other airlines regular seating

Cons: Literally everything.

Pros: excelente

Pros: Good flight.

Pros: arrived 20 minutes early, took off on time

Cons: We had to wait an hour for our baggage from when the plane started de-boarding

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.

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

Pros: when at O'Hare, it was not a very long taxi to get to the gate

Cons: flight was delayed an hour; I felt very cramped in that small space for my seat

Pros: It was on time. Very good overall. 4.5 stars. Can't get the stars to show correctly

Cons: The plane itself was rattling the overhead storage bins in the descent. In The ascent and descent, a little bumpy now and then.

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

Pros: The Crew

Cons: The Flight was delayed 7 hours

Pros: Great deal!

Cons: A little cramped

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: WE GOT CANCELLED

Pros: Nothing

Cons: Once you add in the cost for bags, water, a seat assignment, etc., you've paid just as much as you would on any other airline, BUT you're still stuck with ridiculously tiny, cramped, uncomfortable seats that don't recline, are too narrow, and too close together. Spirit tries to make you believe they are a low cost option, but it's actually a rip off. I should receive 50% of my fare returned to me for the 50% of my seat that was unavailable for me to use because the guy next to me took up his seat plus half of mine. This is because Spirit had its planes designed with more seats crammed in to a small space than the other airlines have. They claim this is what allows them to offer lower fares, but now I have to see a chiropractor because of the twisted position I had to sit in for 4 hours.

Pros: Crew was very nice and attendant that did the announcements was hilarious. No idea about food or entertainment because there wasn’t any. 2 hour flight.

Cons: NO TSA PRE-CHECK!! That’s a dealbreaker Seats didn’t recline

Pros: Crew was great.

Cons: Plane was 45 minutes behind schedule, boarding, take off and arrival. Has to walk miles from gate to ground transportation at midnight when airport seemed dead.

Pros: What few staff hadn't quit were really hard working and courteous.

Cons: The ownership and senior management of this airline are incompetent losers. Flights were delayed both ways. Bags were lost for the entire trip. Zero customer service to help either way. Zero. Four emails written with zero replies. Total losers run this thing. Stay away.

Pros: on time and efficient

Cons: gave me seat in row 30 when other seats were empty

Cons: Late departure

Cons: The seats are small but I'm also a big dude so that might be a factor

Pros: Awesome flight! Southwest loads passengers quicker than any airline I have been on. Great at providing a wheelchair for my 85 year old father.

Cons: The flight was perfect. I wish they offered more direct flights. It would have been impossible to take my Dad to Houston to see his very ill son without the direct flight. Our elderly can only handle direct flights.

Cons: Flight delayed And wrong message of boarding when flight was delayed

Pros: Wifi and free movies, snacks, friendly crew

Cons: Terrible turbulence throughout the entire flight, I was unable to get comfortable and everytime I fell asleep my neck was jerked from the movement of the plane. We were told it would only be a few bumps but it turned out to be a very bumpy 4 hour plane ride! I was very anxious and uncomfortable

Cons: Seats were horrible

Pros: Nothing

Cons: I scheduled to fly Denver -> Chicago -> Fort Lauderdale. They cancelled my flight and put me on a terrible flight (Denver -> LA -> Fort Lauderdale) without telling me. So I cancelled their new itinerary for me and flew southwest. Spirit sucks.

Pros: Good thing I travel light! I thought the round trip fare was great!

Cons: Seating was cramped and seat back did not move

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

Cons: Plane left 4 mins early knowing that passengers were on a delayed flight.

Pros: Amazing crew as always

Cons: Wifi on smaller hoppers

Pros: Horrible storms kept us in the air for at least an hour past our scheduled landing time. And yet we experienced virtually no turbulence. The pilots did an excellent job of keeping us updated, kept things as smooth as possible with the bad weather and we had plenty of movies and games to choose

Cons: I was charged an extra $100 because my bag was 10lbs overweight. Where is this crazy fee communicated on their website? And why does it have to be so much? I didn't have a way to weigh our bag before we left. I had no idea it was so heavy - ridiculous price.

Pros: They were great & super friendly!!

Pros: Nothing

Cons: Over 5 hour delay and no accommodation. We received a lousy $10 food voucher yet everything in the airport is at least $12. Never flying Frontier again.

Pros: arrived 20 minutes early, took off on time

Cons: We had to wait an hour for our baggage from when the plane started de-boarding

Pros: Got to Chicago safely

Cons: Flight was two hours late. One of the flight attendants was hard to understand and cut her sentences short and giggled a lot. No explanation for delay. I asked a flight attendant why so late. "Delayed out of Chicago". Plan made s terrible rattling noise on takeoff.

Pros: on time and efficient

Cons: gave me seat in row 30 when other seats were empty

Pros: Boarding was quick and efficient.

Cons: Seats were kind of uncomfortable.

Pros: On time

Cons: Seats pitch very uncomfortable. Hate paying for carry on. Landed at O'Hare to a series of steps, 3 flights with the carry on I paid for. Had to get off plane outside.

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: My flight was delayed 7 hours. I never recieved an e-mail letting me know of this even though I gave my email when I bought the tickets so that I would get updates on the flight. I checked the flight status before leaving my house at 2am and the flight was still on time. After driving 2 hours to the airport and going through security I found out that my flight was being delayed 7 hours and no representative was even at the gate to speak with. All I was given was one $14 meal voucher which didn’t even cover a full meal at the airport. It’s told that the issue was mechanical but I later found out that te first flight had been over booked and the 1pm flight didn’t have enough people on it so they made everyone on at 6am flight wait until 1pm to fly out. Once on the plane, the seats were hard and uncomfortable and the plane was cold. I am extremely disasiflied and will never use Spirit again.

Pros: Price
