Find cheap flights from Detroit to Denver

Cons: "Flight apparently was cancelled 48 hours before but no one contacted me. I was able to check in with Frontier and get the gate and seat assignment even though the flight had been cancelled the day before. I found out when I arrived at the gate at the airport. Frontier did nothing to help me get to my destination. I was forced to buy a last minute ticket on another airline to get to my business meeting."

Pros: "The flight was on time"
Cons: "Frontier never has enough staff to handle checking baggage and they nickel and dime you for an uncomfortable seat."

Cons: "The worst airline to fly on. Over sold flight by 4 people all checked in so didn't have a seat. Took us over 30 min to get through security and then had to run to gate only to have the manager yell at us to get on the plane. Take note.... we were traveling with a 16 mos old."

Cons: "Poor check in experience"

Pros: "Quck, friendly staff"
Cons: "Tight seats, no water offered to drink"

Cons: "From the moment that I get off the plane to catch my flight connections to San diego, I thought the gate was far but its right the corner so I dont need to rush lol"

Cons: "On time and average comfortable"

Cons: "More delay notices and flight departure changes than I can count. Conflicting times in email notices versus the app versus text alerts. Customer service went straight to voicemail. I may have been able to drive across the country faster. Currently arriving in Denver. My connecting flight left yesterday."

Pros: "Getting off plain"
Cons: "The total experience with Frontier"

Pros: "Price"
Cons: "Only 1 cup of water. Aisles very narrow."

Pros: "Nothing"
Cons: "Flight left Over 1 hour left. Waited on runway."

Pros: "We landed"
Cons: "Nothing"

Cons: "Wasn't calling by zones, was pretty much a free for all to get on the plane."

Pros: "The crew was friendly"
Cons: "Starting with boarding- what happened to loading the back of the plane first? That was much more efficient! That way the people in the back don't have to wait for row 8 to get settled before the rest of the plane can proceed with boarding. Once you get to your seat, it's so uncomfortable! They're molded in such a way your head always leans forward, they don't recline, there's very little leg room or side room. Arm rests are half the size of the usual, and tray tables are also half the size! If you're on the plane for an hour flight, it's do-able, but any longer than that, you'll be miserable. For the record, I'm tall and thin, and I felt squished sideways."

Pros: "nothing"
Cons: "no free drinks? 2.99 for a coke? no pretzels? why i had to pay 70$ for my bags what"

Pros: "On time, nice seats"

Pros: "Very smooth check in since I paid for my baggage and seats prior to getting to the airport and I also had my boarding pass already printed off."
Cons: "The screaming child sitting next to me for the ENTIRE flight."

Pros: "Gate crew at Denver on May 2nd (afternoon) were just disorganized and confused. She was just stressed out for no reason. Seems like not a people's person and can't stay calm at ALL. Can't handle stress at all"

Pros: "Fun time great flight"
Cons: "Great friendly people"

Pros: "Overall, I was VERY happy with both my flights. I've been flying Spirit the past few times I've traveled and after flying Spirit for so long Frontier was a breath of fresh air! The lines to check in our luggage were minimal, each flight arrived about 30 min early to our destination, we got our luggage back in a timely manner. Operationally, our flying experience with Frontier went without a hitch!"
Cons: "No major complaints. As I mentioned, we've had been flying Spirit quite often and after so many headaches with flying that airline I was happy to pay a little bit more to fly Frontier and not run into any complications of any kind! Thank you for being operationally on top of your game Frontier!"

Pros: "They give front of line privilege to military."
Cons: "The plane was uncomfortable. The seats do not recline, there's no where to charge electronics and the planes were dirty. Both of my flights were delayed by two hours and updates of the flight status was not updated while little information was provided as to why the flights were delayed."

Pros: "There is absolutely nothing I liked about Frontier"
Cons: "Flight was cancelled and not rescheduled. I had to spend another $600 to fly out from Detroit that day in order to make it home for Christmas. I will never fly frontier again."

Pros: "Seats were bigger than I thought."
Cons: "Seats didn't recline."

Pros: "I've learned to pack whatever I need into a backpack that's within their personal item limits. This makes traveling on cheap flights easy."

Cons: "Limited space and no amenities"

Pros: "Inexpensive ticket prices."
Cons: "Officially the worst chair I have ever been seated in. Not just on an airplane, the worst chair I have ever had the displeasure to sit upon. Even when the plane was not as full, there was no way to get a single moment of comfort."

Pros: "Like fact was affordable. Was not vacay but taking care of family member after surgery."
Cons: "I paid three times the amount for return ticket to LAX. No help from employees I dealt with. Was because I had changed return date twice. Lost two tickets due to change. Guess I really messed up but it was all due to FAMILY emergency. No love"

Pros: "They miss my bag in Denver"

Pros: "Flight attendants were kind and informative, there was still some leg room even though they obviously squeeze seats in. After the delay, they were quick to reschedule any missed connecting flights."
Cons: "We waited a half hour after boarding time to board, and then waited on the plane for an hour before beginning takeoff. Nothing available to eat or drink besides water or for purchase (I realize this is budget, but this always turns me off). Seats don't recline."

Pros: "The price of the flight... Crew was cool"
Cons: "Paying extra for an emergency exit seat and then on the plane what I paid for was non existant. Pretty shiesty if you ask me. Plane was dirty, wrappers not picked out from seat pockets. Seemed similar to a cattle car"

Cons: "My suitcase was broken into things are missing and frontier operator didn't seem to care said I wasn't missing enough to warrant a claim"

Pros: "They were on time."
Cons: "There was a charge even for soft drinks."

Cons: "When I booked the flight I was not given any information about paying for baggage ahead of time. Much to my surprise when we checked in we found out that carry on baggage was not free, and that we would have to pay to check bags. The plane itself felt especially cramped, crowded and flimsy."

Pros: "The flight was on time."
Cons: "I had to pay 40 for a carry on bag, although I'm pretty sure not everyone was made to pay that. In addition, when I went to check into my flight there was no attendent at the ticketing counter because there was no flight for 2 hours. The whole reason I get to the airport early is so I can battle the TSA line not wait to check in."

Cons: "They overbooked the flight, so we were told to get there two hours early, 3:30am! So we wouldn't loose our seats. The plane wasn't even full. And security doesn't open until 4am. A bunch of BS. They charge for carry on. They charge for check in. They charge for your seat selection. They charge for any type of good or beverage on the plane. $2 just for a small cup of coffee. I am surprised they don't charge to use the restroom. All the money I thought I saved from flying Frontier was quickly used to pay all the extra fees."

Cons: "My flight departed over an hour late, because the airplane arrived long after the scheduled departure time. I was just able to catch my connecting flight."

Pros: "Flying through the air"
Cons: "Everything"

Cons: "It took an hour and a half to get the checked bags from the plane to the baggage claim."

Pros: "nothing"
Cons: "worst airline ever"

Pros: "Direct flight and original time schedule!!!!!"
Cons: "Didn't care for the 3 hour flight delay. Flight was supposedly delayed due to thunderstorms in the east. Was a bit disappointing and frustrating."

Pros: "Trip boarded on time. Personnel were very friendly."
Cons: "Paying $1.99 for coffee. Sitting on the tarmac in Denver for over 20 minutes because we came in early and there was a plane at our gate. The seat I sat in (5A) was filthy and the floor was disgusting. Also, for sitting so close to the front, there was no additional leg room."

Pros: "ZERO"
Cons: "NOT HAVING OUR BAGS"

Pros: "Flight attendant's humor"

Pros: "It was on time. The crew was generally friendly. The take off and the landing was pretty smooth."
Cons: "I didn't like the cramped feeling. I was in the aisle so there was nowhere to rest my head."

Pros: "The staff on board was nice."
Cons: "For starters when checking in at the ticket booth they don't take cash. I had to buy a prepaid card and pay 45 with card fee to check one 30lbs bag. Then I had to sit in one of the most uncomfortable seats. Everything on flight as far as drinks and snacks went was purchase only . no wifi was available not even to purchase.. Then when I got to my destination my bags where not there I had to wait till 4:45pm the next day. No refund was given for baggage check they made it seem like it was no big deal."

Cons: "I don't like to pay for my carry-on or my seat selection. The seats are very uncomfortable. The staff was crabby. I will not fly Frontier again."

Pros: "roomy-ish seats for a domestic flight, however when the folks in front reclined, I could not use my tray table..."
Cons: "When you go to check in and choose your seats, each seat has a dollar amount...I thought I already paid for my ticket!! What they don't explain is that you can check in at the airport and get your seat assignment (without paying extra) and leave it to chance, or pay for a seat reservation in advance. Water was free...that's it. You could buy "snacks" with a credit card only. We sat on the tarmac for 1/2 hour waiting for another flight to leave...this airline company feels new, like they are "flying by the seat of their pants"...in the long run, I paid the same amount as a more well known carrier, so I don't see the benefit to their "spare" and "more affordable" approach."

Pros: "Breckinridge Bourbon!"
Cons: "Flight was delayed 6 times for a total of 5.5hrs later than scheduled. Ruined all manner of plans. Was issued a meal voucher literally minutes AFTER every restaurant in the airport closed. Baggage fees are ludicrous."

Cons: "VERY uncomfortable seats!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

Cons: "No social distancing, every seat was taken"

Pros: "Crew was nice. Flight was on time!"
Cons: "Leg room"

Pros: "It was timely and smooth."
Cons: "Not a big deal at all - but the long line to sfand at a kiosk just to get a luggage tag was a new experience."

Cons: "I didn't like the shady way Spirit goes about explaining the baggage fees and seat fees and $45 for a carry on in my opinion is GOUGING!!!!!!!"

Pros: "Nice trip."

Pros: "Boarding process."
Cons: "Hidden fees of Spirit Airlines"

Pros: "they put me on a delta flight (5hrs later)"
Cons: "the flight was canceled and the delta flight was delayed"

Cons: "Flight was delayed for over an hour but was never notified of how long of a delay or a new gate change until after we were already suppose to be airborne."

Cons: "Still no refund after 6 days on checked in luggage that was no checked in during our flight"

Cons: "Spirit advertises lowest fares, but nickel and dimes you for everything! By the time it's all said and done, I could have flown with a better airline that offers free carry on, lower checked luggage fees and free beverage and snack! The seats were extremely hard, small, and did not adjust, making Spirit the most uncomfortable travel experience of my life!"

Pros: "boarding was fast"
Cons: "the kiosks didn't work, there was a long line, no one explained it was for baggage only, there was someone in another line that I found after I was in first line for 30mins doing the tickets, then she left w/o warning, no one at the counter for a while before another stepped in. Also, poor customer service, yelling at passengers to step up to line, waving them forth to counter rather than stating, 'next please'. Not friendly"

Cons: "They charged us an arm and a leg for our carry on!"

Pros: "The low initial ticket price"
Cons: "Having to pay for a seat and baggage after buying a ticket. I got an earlier standby Delta flight on Friday so I skipped the first Spirit flight (which ended up being delayed anyway). On my flight back to Denver today, I found out in the terminal that my entire trip was cancelled because I missed my original outgoing flight. I was never notified of this cancellation through email or phone call. I was then asked to pay another $200 for a one way ticket back to Denver. Luckily I was able to fly standby on Delta again instead. Never flying Spirit again. Terrible customer service as well."

Pros: "Thank you to the staff member who got us through TSA in order to board our flight on time. Very close call. Without her quick thinking we would not have made it home in time for my sons first day of his new job as a lifeguard for the YMCA."
Cons: "Spirit check in line to check bags was ridiculous. Waiting an hour before getting pulled out to fast track the line for our Denver flight."

Pros: "Quick. On time."
Cons: "Seats don't recline :/"

Cons: "There was a 45 minute flight delay."

Cons: "Flight was announced as cancelled 3 hours before boarding time, then 2 hours prior to boarding was announced it was running on time, then delayed 6 times. Although I paid for a seat reservation so I could sit next to who I was traveling with, Spirit separated us and would not refund me the cost. Agents at the gate were not helpful or friendly."

Pros: "cheap fares"

Cons: "3 dollars for a Coke"

Cons: "The flight was cancelled due to a crew issue at Spirit. The airline did nothing to assist in rebooking. Had to buy a ticket on another airline."

Pros: "Everything on time, flight happened as it should"
Cons: "Seats are really small. I had difficulties fitting in"

Cons: "Spirit broke my luggage. The staff was very rude. And hidden fees are everywhere. It's worth it to pay 20/25 more on a ticket with out hidden fees. Never again."

Pros: "Nice big seats!"
Cons: "No free drink (including water)"

Pros: "Price"
Cons: "Tiny tray table"

Cons: "Even though the airline is cheaper than most, be causios for extra charges!!!!! Double than other airlines on baggage! If you have a bag to check in, read their prices before you book a flight!"

Pros: "Nothing goog to say."
Cons: "They canceled this flight due to an employee calling in sick. My husband slept in airports for two days before Christmas, finally showing up in Colorado in the middle of the day on Christmas. Thanks a LOT Spirit!"

Cons: "Every thing"

Pros: "I liked the VFW lounge and the free amenities for us veterans"
Cons: "Everything els, horrible everything..will never fly Spirit again"

Pros: "Other than the four hour delay? Nothing, nothing at all."
Cons: "Ditto"

Pros: "On time and staff very accommodating"
Cons: "No much leg room"

Cons: "No entertainment. The trays are way ti small."

Pros: "The seats were awesome and there were 20 seats available so I got to pick any seat."

Pros: "Super cheap fares if you pack a backpack instead of a "rolly" carry on or shoulder bag!"
Cons: "Very tight squeeze in the middle seat. Worth it to save $150."

Pros: "We tried to pre-register through the website and we couldn't website was horrible they charge to change seats and they charge for carry-on luggage which I've never heard before on any airline they try to nickel and dime you to death. I highly recommend you don't take this airline ever"
Cons: "I went to my dads funeral and they wanted to charge me for baggage changing seats and completely unprofessional I recommend not flying with spirit ever again the website was broken and could not pre-poured the night before"

Pros: "Nothing"

Pros: "O"
Cons: "BEFORE YOU GET ON THE PLANE SO MUCH EASIER ON DELTA I WILL NOT BE BACK"

Pros: "Nothing"
Cons: "I arrived 2 hours before my flight and needed to drop off my checked bag. I waited in a huge line at the detroit airport. I made it into the roped section of the line then a "last call" was made for Denver flights and they went to a different line. I was told (with a bunch of other people) that since we were into the roped section of the line we should stay. Then all the denver passengers behind were brought to the front and the people that were told to "stay in line" got screwed and failed to make the flight due to simply trying to check baggage. Approximately 30 of us were told to go down to the spirit office to rebook flights. The office workers were no help and very unsympathetic to the fact that people's travel plans were ruined. I ended up having to rebook a new flight from a different provider that day to protect my other plans at my destination."

Cons: "To start, when we arrived at the Detroit airport at 5:30am for our 7am flight, the line to check bags was clear across the building. It eventually got to the point where they had to make a special line for our flight to check in at around 6:30am. Fortunately we were towards the front of that line and when we finally got through security we raced to our gate and made it just before they were about to close the doors. There were many people behind us still trying to make their way either through the check-in line or security and we tried to speak up and tell the flight attendants just that as they announced we were shutting the doors and about to push back. One lady sitting near us was on the phone with her friend whom she was traveling with that was at the gate along with a dozen other people trying to get on the plane. When we tried to tell the flight attendants to wait, one flight attendant had the dignity to come over to me and said "if my party wasn't on the plane then I could get off the plane." Finally, they opened the doors one last time and about 15 people came through, however, there were still plenty of open seats on a flight that typically is quite full so I'm certain many more missed the flight. Once we got to Denver it was no surprise that only about 12 pieces of luggage came through the carousel so more than half the plane was missing their luggage. We were then told that if we had a late check-in, which everyone who checked luggage did, then we would have to come back to the airport to retrieve ti. Fortunately, they made an exception for our flight and our luggage was delivered the next morning. All in all, I'm extremely disappointed and frustrated with the way Spirit handled everything, with the exception of finally agreeing to deliver our luggage. The lack of communication, efficiency, and concern, between everyone at Spirit, those checking people in, the flight attendants, the luggage crew, the person in charge of lost luggage, is so unacceptable. From now on, I will gladly pay more just so I NEVER have to fly Spirit ever again! They not only lost my business but also from those who were on the flight with us standing in line to file our lost luggage claim as well."

Pros: "Friendly staff."
Cons: "The checking in process was fine, as Long as you added your carry on bags within the same process for a smaller fee. However, the "random seating" option that you choose is not actually choosing a seat; therefore I was denied boarding even when I checked in and my seat was given to someone else. I was told nothing until the plane left the terminal and I was told to "get comfortable" while waiting. An hour later, I was given the option to fly the following day home to Denver with 3 layovers, and a full day of traveling. Its hard to travel this type of airline when they have complete disregard for personal plans and do not communicate with their customers the hidden fee's. Bare fare is a way of saying you are paying for the possibility of flying, not even a guaranteed seat."

Pros: "Everything people say about Spirit is true... you get what you pay for...and then more payments on top of that...."

Pros: "Professional ,cheerful staff. Smooth flight"
Cons: "Cramped seating... Lack of leg room"

Pros: "Ng"
Cons: "Thought spirit wasn't a rip off before think again. Spirit now charges u to take a damn carry on. I paid 55 dollars for my carry on bag now you do get a personal item that is the size of a purse. Ok sure let me pack 4 days worth of clothes into a purse it's so ridiculous. Never flying spirit again."

Pros: "Everything went as planned. This is a direct flight with no layovers or stops."
Cons: "The prise for a carried on bag. $55 dollars is to high. Should be $35 dollars at the most."

Pros: "No frills or hassles"

Pros: "The crew was very nice"
Cons: "The leg room wasn't there. We were very cramped there was no entertainment at all on a 3-2 our flight almost three-hour flight. Water is not even free you don't even get a courtesy copy of papachooz everything is paid for it was cold on the plane they didn't have a blanket. I hate spirit I would rather pay the extra for the ticket price and have some conference and some amenities than a beer flight price and be miserable 2 to 3 hours on a flight this horrible Spirit needs to do better"

Pros: "It was on time and got me where I needed to go."
Cons: "Nothing was done to dislike,nothing."

Pros: "The crew was friendly. I've always found Spirit employees friendly. Save on this flight the one flight attendant, when I asked if their was WiFi on the flight replied, "Only in your hopes and dreams honey.". That was a little unprofessional."
Cons: "Man, I really want to like Spirit but now that I've been making money for a bit I just can't justify the annoyances. No WiFi on some flights, no TSA pre-check (that's HUGE) Why Spirit? Why? The baggage fees too. I get the low-cost carrier thing, but some of these things just don't make sense anymore like not having WiFi."

Pros: "Staff"
Cons: "Seats are a little cramped"

Pros: "The only good part was finally getting off my flight."
Cons: "The plane was sitting there but we didn't board till an hr and a half after the time we were supposed to leave. The seating is very tight. They charge a lot for carry on and checked bags. Everything's costs on the flight including water. They tried selling us on a spirit master card for the last ten mins of the flight by offering free miles."

Pros: "Not much"
Cons: "Flight delayed 1hr but plane was at gate on time. Obviously crew was over scheduled. Totally spirits fault. Late arrival caused a hungry nite for my family as restaurants closed when we arrived. Cost skyrockets due to all the charges. $3 for a soft drink??????"
