Find Cheap Flights from Miami to Colorado

Pros: Service was nice

Cons: Uncomfortable and cheap feeling

Pros: Nothing

Cons: I had an early morning flight. When I arrived there was no security setup so I had to wait in the ticketing area for 2 hours. Then when I got to the gate I plugged in my phone and fell asleep before I could get an alarm set. They knew I checked in and made it through security and had to see me alone sleeping there and made no attempt to wake me and I woke up to see the plane deprating and the crew gone. When I went to ask the counter what happened they said it was my fault and I should have listened to the announcements. Then tried to charge me $100+ for a next day flight. Terrible, horrible, rotten customer service, I mean who could leave someone stranded unless they were just trying to make more money? Delta would never pull that garbage.

Pros: Check in was easy and the flight timing was great.

Pros: I would rather spend an extra 30$ and fly american or any other airlines.

Cons: Pretty much everything especially the customer service

Pros: No major screw-ups this time!

Cons: It's AA, let's not try too hard here.

Cons: The plane was so small no roller bags could be accommodated. All bags were gate checked. Retrieving all those bags while on the jetway was difficult

Pros: Staff, plane, ride - one of the nicest flights I've had in a long time

Cons: Nothing. Well, if you paid me to fly ;)

Pros: Amazing plane and service

Pros: United does it better than low-cost carriers

Cons: Not worth the additional cost over low-cost carriers

Pros: We made it home safely and on time.

Cons: We were sat in the very last seats near bathroom which was noisy and uncomfortable. I actually paid an extra charge so we could be sat together. In flight entertainment didn’t work in my seat. One piece of our luggage was lost.

Cons: Seating very tight. Difficult to get in and out, or to get your things from under the seat.

Pros: The crew was polite and helpful

Cons: The food was very average

Pros: Boarding was easy for a large number. Seats were comfortable. The crew was pleasant and attentive. The food was very good actually. Love the Mile High Tea!

Pros: Yes Crew was amazing. Seat was comfortable

Cons: No comment

Pros: Yes, . Amazing crew Seat was comfortable.

Pros: Empty row!

Cons: Movie selection More new releases

Pros: Landing safely.

Cons: We were an hour late in boarding and no one told us why. The seats are horrible - stiff and plastic, unable to recline. Our return trip from Miami was to leave at 7 am.. We were in line to check in at 4:45 am. There was a notice stating they wouldn't start checking us in until 5:05. No one was there. Finally two young ladies sauntered over to the desk at 5:45. Frontier leaves so much to be desired.

Pros: The app is decent and user friendly.

Cons: Boarded on time, took off 75 minutes later because I think someone clogged the toilet prior to take off. The seats were very uncomfortable - not a lot of cushioning, couldn’t recline, very narrow arm rests. The flight attendants were not the most hospitable as well. I did not receive a drink the entire 4 hour trip. The plane was just very minimalistic.

Cons: I was sent an email the day before to do an early check in, so I did. Once I filled everything out, the next screen said I was "good to go." When I arrived at the airport the next day, after getting lost, 40 minutes before my flight was supposed to take off, they said I had not checked in and that it was too late. I then had to spend $180 on an American Airlines flight as getting to Denver was not optional for me. I will NEVER fly with Frontier ever again.

Cons: Nickel and dime for everything. Plastic seats which in a sudden stop or crash would cause head injury. We sat on tarmac for 3 hrs before departure so they could locate passengers to fill every seat even though boarding was supposed to close after 30 minutes. I could go on.

Pros: Staff, plane, ride - one of the nicest flights I've had in a long time

Cons: Nothing. Well, if you paid me to fly ;)

Cons: The plane was so small no roller bags could be accommodated. All bags were gate checked. Retrieving all those bags while on the jetway was difficult

Pros: Comfortable

Cons: I was in 10C a So I was able to hear a disgruntled AA employee. Just like office politics. But up in the air. I didn’t need to hear

Pros: Non-stop flight and arrived ahead of schedule

Cons: No individual entertainment in seat backs and the common system wasn’t working. But, since it was an overnight flight it wasn’t that disappointing

Pros: N/a

Cons: Extremely uncomfortable seats that don't recline, a folding table that cannot even hold a book. Will never fly frontier again

Pros: I liked that we didn't crash and arrived to Denver safely.

Cons: When getting my boarding pass I was told I did not need to pay for my carry on as it met Frontier's requirements. When I arrived to the gate, I was told I had to pay $60 for the carry on. I explained the situation and the woman at the gate kiosk said she would "tell her supervisor and get the lady in trouble." The woman's urgency to so hastily throw a co-worker under the bus demonstrated a lack of "unity" among Frontier as a whole. When I got on the plane, there was no room for my "carry on" I just paid $60 for. Subsequently, I was told to bring my bag to the back, then to "bring it to the front", finally resulting in having to have it checked. We were forty minutes late taking off and neither the pilot or crew was apologetic for the inconvience. During the flight, a man expressed concern for my situation and being misinformed about the bag requirements only to result in being penalized and having to pay a $60 fee. The flight attended, assuming I was asleep, and having no knowledge of the situation, said "that's what she gets for trying to sneak her bag on." The unprofessionalism of the situation was again, extremely evident and portrays a negative image of Frontier as a whole. At the very least, the women could have honored the price to carry on/check a bag online or self service kiosk. Upon landing, I legitimately verbatim said to the man in front of me "$20 bucks we don't have a gate." Almost immediately upon saying this, the pilot said "unfortunately, Denver Internstional Airport has an ongoing issue with flights getting a gate so passengers can deplane." Had this been the first time this has happened, it would not have been an issue. I fly very frequently and have never had this issue with any airline except Frontier and Spirit, which..coincidently are owned by eachother. Not only is the issue specific to Frontier and Spirit, it is an ongoing issue. We waited in the plane for 45 minutes and the worst part? The pilot didn't even have the audacity to apologize. Instead, he blamed it on the airport. Again, failing to demonstrate any sort of professionalism. I am very disappointed with this experience in it's entirety. Last time my friend flew to Vegas on Frontier, the pilot said "Apparently Spirit couldn't afford a gate." While it was frustrating, at least he was able to make light of the ongoing issue. The passengers then got off the plane, right there on the taxi lane. I took the earlier flight that same day from Vegas to Denver and had the same situation, only we waited nearly 2 hours to get a gate and deplane. Again, no apology and purely blaming Denver International Airport. It is baffling that any airline would have the audacity to blame an entire airport dedicated to the well being, safety, and travel efficiency of the people who come in and out of it. Frontier's failure to acknowledge and express apology concerning the reoccurring issues of the airline is concerning. Did I mention the smell of urine filled the entire back of the plane

Pros: Service was nice

Cons: Uncomfortable and cheap feeling

Pros: There is not one positive thing I can say about my experience with Frontier.

Cons: Where do I begin, the counter opens 2 hours before flights, and in our case it opened 90 minutes before, so the line was horrendous. Be ready to pay through the nose for well...EVERYTHING. Our luggage cost us over $200.00, our seats over $300.00 even a coffee was $2.99. The seats are ridiculous. We paid for the expensive seats thinking that meant we'd have extra leg room, and you know a reclining seat...haha!! No, we were wrong! We had LESS leg room because we were in the first row , we had to hold our purse/backpack in our laps because the overhead was full (Even though we were in row A! The flight attendants allow people to put their baggage anywhere, not necessarily over there seat, so we were screwed). Our seats were like sitting on sharp metal objects. We were 35 minutes late leaving the airport, the crew didn't see fit to tell us why. The luggage took twice as long as other airlines to get to.the terminal... In a nutshell this so called "cheap fare" winded up costing us over $1,000.00 once all extras were added. We will NEVER fly Frontier again.

Cons: Larger plane. Had to crouch all the way to my seat. Seat was comfortable enough.

Cons: Excellent flight

Pros: The plane looks like new. Great seats, phone and tablet holders at the seat back, USB outlet and a smooth flight.

Cons: The WiFi did not work and so no entertainment for a flight of almost 4 hours.

Pros: Gate folks were professional in spite of late incoming flight causing late departure, late on a Sunday night, and full load of home bound passengers.

Cons: Again, horrible seats. Could actually feel and see the support bars. Come on AA this is not hard.

Pros: Crew was great.

Cons: Expensive carry-on fee. Delayed flight. Incredibly uncomfortable seating, especially with a bad back. Would definitely choose another option if there was another economic choice in airline.

Pros: Absolutely nothing, worse airline ever.

Cons: The change of my flight. I buy that flight because I like the original times but then they change it making me wait 10 hours in Denver and making me leave Miami way to early instead of taking off at 1pm on Sunday I took off at 7am. Absolutely ridiculous and then in Denver I took off at 7:30pm.

Pros: Ok

Pros: Boarding process was easy. Baggage check was friendly. Crew was very nice but everything else offsets that for my rating

Cons: Airline was terrible. Uncomfortable seats that don't recline. No wifi. They charge for every drink even non alcholic. Seat selection and carry one are also charged for when you check in. I would rather pay much more and fly a modern airline

Cons: Larger plane. Had to crouch all the way to my seat. Seat was comfortable enough.

Cons: Caterer was late causing plane to be 45 min late taking off. All so first class could eat while we're had pretzels

Pros: Amazing plane and service

Cons: Excellent flight

Cons: Flight took off an hour late, no video monitors on seats for 6 hour flight, all 3 of our bags did not arrive. Sun country unresponsive to trying to locate our bags. I will never fly with them again.

Pros: Crew and price of tickets was great

Cons: Having a carry on included and having a small snack.

Pros: Unlike some airline pilots(Spirit) these guys actually communicate with the passengers.

Cons: Have working charging ports, improve space for comfort.

Pros: The crew was amazing - friendly and efficient!

Pros: The flight was good.

Cons: The seat size could be bigger, and the layover was awful. Sixteen hours is unheard of.

Cons: Caterer was late causing plane to be 45 min late taking off. All so first class could eat while we're had pretzels

Cons: The plane was so small no roller bags could be accommodated. All bags were gate checked. Retrieving all those bags while on the jetway was difficult

Pros: No excuse on a night flight does the temperature to be 80 plus degrees on the plane.

Cons: The plastic seats and extreme temperature was brutal. They shut the AC off of down somehow.

Pros: The flight itself was good however, the cancellation/rebooking process by the airline carrier was less than satisfactory.

Cons: The airline carrier was not very accessible. I was on hold for a long period of time (during late night hours) for questions.

Pros: Smooth ride

Cons: So we arrive at our designated gate (D19) about 90 minutes early--time enough to get something to eat. We grab a quick bit, head back to gate with an hour to spare and sit down figuring we'll start boarding in a half hour. There are two agents at the gate, but there is another passenger there crying about the something in Spanish (it appears she missed her flight). Eventually airport security shows up. Well, the half an hour boarding time comes and goes, and we don't start boarding. We figure it has something to do with this woman. Finally, I go check the board again and they moved the gate to D15! We rush over, but we missed the flight. So did half a dozen other people. No announcement, nobody walking over from D15 to D19 to see if there are people there. We get to American counter and we get several different sorry-ass excuses. The first was that Miami likes to keep "a quite airport." The second was that it is OUR responsibility to check with gate agents if they don't start boarding on time. I'm so tired of the airline industry arrogance and treating passengers like they're doing us just a tremendous favor by allowing mere mortals like us to be in their very presence and allowing us access to their magical flying machines.

Pros: The plane looks like new. Great seats, phone and tablet holders at the seat back, USB outlet and a smooth flight.

Cons: The WiFi did not work and so no entertainment for a flight of almost 4 hours.

Cons: I did not appreciate how they charged you for every bag (including carry-on), every service, and every tiny thing. The service from the desk, to baggage handling, to in-flight felt very negligent and half-hearted. I will not be flying Frontier again.

Pros: The app is decent and user friendly.

Cons: Boarded on time, took off 75 minutes later because I think someone clogged the toilet prior to take off. The seats were very uncomfortable - not a lot of cushioning, couldn’t recline, very narrow arm rests. The flight attendants were not the most hospitable as well. I did not receive a drink the entire 4 hour trip. The plane was just very minimalistic.

Pros: Frontier provided hotel vouchers for the night along with food vouchers. Even though there was a bit of a waiting game from time to time, everything was organized.

Cons: Upon arrival to the Kansas City, MO airport we were instructed to stay on the plane for an undetermined time. We were offered snacks for purchase. I think they could have spared some free snacks considering they had already gone through selling while en route.

Cons: The A/C was blasting and it was much too cold! I like to stay cool while in flight, but this was beyond cool. Also, the flight attendants served the guy in my aisle SEVEN bottle of Vodka! He was loud and obnoxious on a 7 Am flight :(

Cons: We should have had less in our carry on so we had more leg room. The staff was friendly and very helpful. There was plenty of movies, tv options, and games to pass the time when we weren't sleeping on the over night flight.

Cons: Flight was canceled and I was left stranded.

Pros: The entire process was a breeze

Cons: I had kids kicking the back my chair & rude Passengers Florida to Chicago. Then connect to other flight from Chicago to Madison & the thing but, different passengers!

Pros: Staff, plane, ride - one of the nicest flights I've had in a long time

Cons: Nothing. Well, if you paid me to fly ;)

Pros: On this flight was a female flight attendant who anticipated my every need. I wasn’t flying first class, but still, she went out of her way to treat me very well. Her personality and hospitality made my flight relaxing, made me feel loved and appreciated, and the flight felt like I was already home

Pros: The plane looks like new. Great seats, phone and tablet holders at the seat back, USB outlet and a smooth flight.

Cons: The WiFi did not work and so no entertainment for a flight of almost 4 hours.

Pros: Friendliness of crew

Cons: Offered more of an incentive for the inconvenience

Cons: I was shocked to be charged a $40 fee for a carry-on bag. This was a hidden fee to me, as I did not know about this charge and no other airlines have this fee.

Pros: Food

Pros: Frontier provided hotel vouchers for the night along with food vouchers. Even though there was a bit of a waiting game from time to time, everything was organized.

Cons: Upon arrival to the Kansas City, MO airport we were instructed to stay on the plane for an undetermined time. We were offered snacks for purchase. I think they could have spared some free snacks considering they had already gone through selling while en route.

Pros: Absolutely nothing, worse airline ever.

Cons: The change of my flight. I buy that flight because I like the original times but then they change it making me wait 10 hours in Denver and making me leave Miami way to early instead of taking off at 1pm on Sunday I took off at 7am. Absolutely ridiculous and then in Denver I took off at 7:30pm.

Cons: Seats are extremely limited in space. I know it’s not only United but I’m an average sized guy and a 4 hour flight is a challenge.

Pros: Good crew, great landing, short flight

Cons: The seats are crampy

Cons: The flight was delayed so I missed my connection, spending 6 hours in the Houston airport

Pros: Crew was very good. Seats were uncomfortable. Too close together and hard.

Pros: The crew was great.

Cons: Nothing.

Pros: The service, on time, employees very nice.

Pros: The crew was so nice and funny!

Cons: The food could be better, but I understand ultimately what it is: mass produced. The pretzel bread is good. The chocolate chip cookie is great. The ice cream is great. The lemon and something cheesecake dessert was too lemony for me, but my mother would have loved it.

Pros: Boarding was easy for a large number. Seats were comfortable. The crew was pleasant and attentive. The food was very good actually. Love the Mile High Tea!

Pros: Tv and power outlets

Cons: This one attendant didn't get her name but was very cold to me

Pros: Gate folks were professional in spite of late incoming flight causing late departure, late on a Sunday night, and full load of home bound passengers.

Cons: Again, horrible seats. Could actually feel and see the support bars. Come on AA this is not hard.

Cons: the new seats are awful

Cons: British Airways but the flights were operated by American Airlines who I've always had terrible experiences with. This was no different. TOTAL NIGHTMARE
