Find Cheap Flights from Colorado to Chicago

Cons: Every flight attendant was fucking gay

Cons: You charges us $50 each way to check a bag . Ridiculous. . Never fly this airlines again

Pros: it was a very smooth ride.

Cons: paying the carry on fee.

Pros: Price was nice. I am quite tall so I also paid to upgrade my seat so the extra leg room was great.

Cons: The website, app, and customer service from their 800 number is absolutely terrible. I don’t know if I’ll fly Spirit again due to the lack of user experience on their site/app and the difficulty I had trying to upgrade my seat both online and over the phone. Everything else was as expected- no frills. No food, drink, carryon, etc.. unless you pay for it.

Pros: Couldn't get Wi-Fi to work

Pros: Everything.

Pros: I know it's some sort of miracle. But there was only 40 people on an airbus. We all had about 3 seats each and we made full beds for ourselves.

Cons: The staff in the main cabin were very impatient and unfriendly. I attempted to buy food and the flight attendant was waving her hand telling me to "hurry up". She was so impolite that I didn't make the purchase. It was less unpleasant to be hungry than it was to interact the flight attendant. It is sad, but this is the standard on most domestic US flights. Im sure I will fly United again simply because their flights go where I need them to.

Pros: Friendliness and being professional

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

Pros: Didn't get beat up or dragged off flight so better than United

Cons: Woman at gate unable to provider updates with when delayed inbound flight be there and when we would be boarding Crew unable to provider estimate with new landing time so that we could update our ground pickup at destination Front bathroom broken on a 40+ row flight! Incredibly inconvenient for passengers towards front especially when they have their snack/drink cart out which no one wants anything from anyway because it all costs money. Get that out of the way! One attendant was rude to my wife and son when they were trying to get to the rear bathrooms. Crew did not know which baggage claim our bags would be at. Won't make the mistake of flying Frontier again because it's cheaper (rude service, delayed flights, no refreshments = cheaper). I recommend other travelers splurge for any other airline (maybe not United)

Pros: It was fine. Seats do not recline . They charge for all beverages.

Cons: 1.5 hours just to drop off baggage after we already had boarding tickets. Employees were rude and scarce. They had many stations but only two people working and they were turtle slow.

Pros: Great non-stop flight!

Cons: More pretzels or maybe a bottle of peanuts

Cons: Bag taking too long to arrive at carousel

Cons: Earlier notification of cancellation

Pros: Quick flight

Cons: Coffee or beverage service would have been a nice touch.

Cons: There was a lot of turbulence and people screaming in fear, it always makes me feel better when the crew says something reassuring to make people less anxious.

Pros: The crew was fantastic. The seats were very comfortable and the entertainment screen functioned perfectly with a great selection of things to watch.

Cons: The boarding process seems slightly longer for delta than other airlines. I figure you’re aware of this and are working on streamlining this. Further while the safety animation yo have made is cute is a little confusing at times.

Cons: Couldn't have been better

Cons: Took over 30 minutes to get my checked bag.

Cons: The flight was delayed which I wasn't alerted about and the gate was also switched gates without alerting us.

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: Being encourage to pray for patience

Cons: The noise. The delays. The not so working speakers.

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: Couldn't get Wi-Fi to work

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: Mechanical delay where the flight attendant kept saying "ten more minute" but it took nearly two hours. Don't overpromise and under deliver. Then we pushed back and got stuck on run way for another hour.

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.

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

Pros: I liked the stewardess. She was nice.

Cons: I pay for my ticket and then there is fees for days!!! Charge me what you will for the ticket but all these after fees are disgusting. You should be ashamed for yourself Frontier you filthy animal...

Pros: Didn't get beat up or dragged off flight so better than United

Cons: Woman at gate unable to provider updates with when delayed inbound flight be there and when we would be boarding Crew unable to provider estimate with new landing time so that we could update our ground pickup at destination Front bathroom broken on a 40+ row flight! Incredibly inconvenient for passengers towards front especially when they have their snack/drink cart out which no one wants anything from anyway because it all costs money. Get that out of the way! One attendant was rude to my wife and son when they were trying to get to the rear bathrooms. Crew did not know which baggage claim our bags would be at. Won't make the mistake of flying Frontier again because it's cheaper (rude service, delayed flights, no refreshments = cheaper). I recommend other travelers splurge for any other airline (maybe not United)

Pros: It boarded quickly, I guess

Cons: Seriously pretty much everything

Pros: On time. Very organized.

Cons: Only airline in the airport with delays from a snow storm 3 days ago!! About 7 hours in the airport with multiple delays before it was canceled. No other flights available for a week. Refunds available (supposedly) but had to wait in lines over 10hours long or through their phone service with significant waits before being routed to their website which was pointless. Some people were waiting over 10 hours to pick up their checked bags from previously canceled flights. Hundreds of flights were canceled the day before as well. Again, this was the only airline in the airport with these issues. Other flights were leaving without problem. I will never fly frontier again.

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.

Cons: They canceled my flight and did not have another one until the next day. I booked with American and had a great flight.

Pros: Great deal!

Cons: A little cramped

Pros: Price, on time departure/ arrival. Easy boarding, courteous service.

Cons: No complimentary soft drink, tight seating, small plane

Pros: The seat. Big and comfy upgrade

Cons: The cost of the big comfy seats

Pros: United representatives were friendly.

Cons: TSA at Denver was the worst I have ever experienced in all my years of flying - they closed down lanes despite incredibly long lines winding around the entire floor of of the security areas, their staff was rude and the lines moved incredibly slowly - mostly because they seemed understaffed and unconcerned with anything other than themselves.

Pros: Good flight overall would book again

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

Pros: Departed on time.

Cons: Small plane...every seat taken and crowded.

Pros: They left me alone.

Cons: Fold down tables are tiny

Pros: I liked the stewardess. She was nice.

Cons: I pay for my ticket and then there is fees for days!!! Charge me what you will for the ticket but all these after fees are disgusting. You should be ashamed for yourself Frontier you filthy animal...

Cons: Air traffic control issues kept us from leaving on time. They did a good job of catching us back up, and even though we were late, they made up time. I like the design of the plane where the seats are thinner and there is more leg room. I had quit flying Frontier because of the measuring of the carry ons, feeling like cattle being herded, etc. This was a better experience, with the exception of the carry on expense. With that and charging for every little thing, your prices are not any cheaper than any other airline.

Pros: Low cost

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

Pros: A everything was fine other than...

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: 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.

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

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.

Cons: They canceled my flight and did not have another one until the next day. I booked with American and had a great flight.

Cons: Very crowded airplane, no room for legs and I'm short, chairs do not recline, expensive to check in bags and they lost my friend's luggage without any proper explanation.

Cons: I didn't get my seat I paid for they did reimburse but that made me a little unhappy

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.

Cons: Very late.

Pros: I got home safely.

Cons: Every time I fly United they manage to screw something up. Two hour delay on the way out. 45 minute delay on the way home while they located another plane (mechanical problems) made my connection impossible. They did get me on a plane to Newark, which was also delayed. I made the connection by the skin of my teeth and a lot of anguish. My luggage did not. All in all, a very unpleasant travel day.

Pros: The crew was very kind to everyone and it was a very pleasant flight!

Pros: It’s not united or AA

Cons: It’s not Alaska

Pros: Easy boarding

Cons: Nothing

Pros: The crew was great.

Cons: It was freezing!!!! All of the passengers were complaining.

Cons: Good flight smooth sailing! On time

Cons: Flight cancelled

Pros: Went smooth without delays.

Pros: Noting

Cons: no room on plane, Baggage cost to much. Could not check bags until after 4 AM in Denver so had to sit at front of airport until boarding no time for breakfast after long drive.

Pros: Crew was friendly

Pros: I was originally booked through jfk with an 80 minute layover. When I told a delta.help desk employee i feared it was too tight (I flew out through jf k and that was enough to convince me...) he booked me through Atlanta with a.comfortable schedule. Thank you!

Cons: Issues with connecting flights so had to sit in different place, seat was broken

Pros: individual TVs

Cons: it would be great if you could not use all those one-use plastic cups. waste is a real issue in the US and the solution is using re-usable items like washable cups. Unboarding was a nightmare and it started to get really hot waiting to get off.

Pros: I liked the entertainment

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: New plane, crew friendly and professional. Arrived early!

Cons: Didn't know drinks were extra before I boarded- next time I'll buy a soda at the airport.

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

Cons: Stewardess over intercom had poor diction.

Pros: Their employees were pleasant enough

Cons: My return flight got cancelled and over 24 hours later I still haven't been able to even speak to their customer service to get a refund. I ended up purchasing another ticket on Southwest because I had to get home and Spirit didn't have any flights until about 24 hours later. The cheapest crummiest airline out there. You have to pay to check in at the airport. You have to pay for carry on luggage. You have to pay for everything. The flight was uncomfortable and they won't even give you water. Literally everything is an extra charge, and there are about 10 pop up screens trying to get you to purchase extra stuff every time you try to navigate their website. I won't be flying them again.

Pros: Noting

Cons: no room on plane, Baggage cost to much. Could not check bags until after 4 AM in Denver so had to sit at front of airport until boarding no time for breakfast after long drive.

Pros: The Crew

Cons: The Flight was delayed 7 hours

Cons: Flight cancelled
