Pros: "I was left high and dry in Denver airport for over 12 hours because I was never notified of the change in connecting flight from AM to PM! I am absolutely livid. The Frontier agents weren't helpful at all in finding me an alternate flight. #wasteofmytime #NeverAgain"
Cons: "I was left high and dry in Denver airport for over 12 hours because I was never notified of the change in connecting flight from AM to PM! I am absolutely livid. The Frontier agents weren't helpful at all in finding me an alternate flight. #wasteofmytime #NeverAgain"

Pros: "The two flights were smooth."
Cons: "My flight was cancelled and me amongst other passengers did not get a voucher for a hotel. So I spent 18h at the SFO airport. My layover in Denver had originally been 2h this time it was 9h. By the time I finally got to Phoenix I have been travelling for over 29h. On top of it all I was charged $45 each, for my baggage as well as my backpack ($90) which I found rediculous!"
Pros: "The plane safely landed."
Cons: "Customer service, overall lack of competence and an inability to communicate laterally with other airlines who were using their gates. Seats are also incredibly uncomfortable."
Pros: "Easy check in"
Pros: "We got there safely."
Cons: "They made the flight more than an hour late so that 12 people could make a connection. I understand having some compassion, but more than an hour? What about the rest of us who, do to the sardine can nature of plane travel these days, had to all listen to each other call their appointment s and explain the delay? Also, they charge for nearly everything -- soda, checked luggage ($45 for one!), carry on. I won't choose Frontier again unless it's my only choice."
Pros: "I called Customer Service as I needed to request a wheelchair to and from gate. The Customer Service Agent was pleasant and accommodating. I while I do not like paying for my luggage to accompany on the flight, I might try you again."
Pros: "Crew Is okay."
Cons: "As expected, anything extra (carry-on, water, food, etc) will be charged extra. Seats are small and do not recline"
Pros: "Didn't take flight"
Cons: "Don't overbook take care of customers. You have booked if you are late for flights you enter into contracts with them follow through"
Cons: "I arrived at the airport two hours before my flight out of Denver. The Frontier counter had a line that wrapped out of the ticketing/check in area and out into the main part of the terminal. I ended up missing my flight because it took me over an hour to get checked in and to security. There were several other flights leaving at the same time where a large numbers of passengers were also going to miss their flights. I've never seen anything like it in all my years flying."
Cons: "I can't believe you have to pay $40 for carryon!!!"
Pros: "Nothing"
Cons: "Delays!"
Cons: "First of all I had to deplane because of sewer issues that took several hours to fix. Caused issues with my rental car. Then a $45 bag fee each way on a 2 hour flight that cost $160. That's freaking ridiculous. They say it's a value to fly frontier when it is a complete rip off plus they wanted to charge for coke. Complete joke. Total dillataunts"
Pros: "Nothing"
Cons: "The whole experience and on top of it they lost my bag. I didn't get my bag in Phoenix they said it stayed in Denver. 6 other passengers experienced the same baggage problem. It was a horrible flight."
Pros: "The cost of the flight"
Cons: "No complimentary beverages or snacks"
Pros: "Boarding was swift"
Cons: "I checked to see how much it cost to pay for my 2 checked bags online, it was 25.00 each. This was on a Sunday. Come Monday I went to pay for my two bags online but now it cost 35.00 per bag, WOW!!!"
Pros: "Got me where I needed to go"
Cons: "Everything is an extra charge after purchasing a spot on the passenger list. Luggage charges are exorbitant."
Cons: "It' time Kayak et.al. start posting prices with the extra's included up front. It seems I should be able to say what baggage and extras I want (aisle seat) before I search and then have prices reflect that. Hunting through the fine print is a waste of time and benefits the airlines not the customers."
Pros: "Not much"
Cons: "This used to be our favorite airline about 6-7 years ago. Now it's just a last minute ticket availability decision for only very short trips!! So uncomfortable, rude attendants and so many fees!!!"
Cons: "Lost luggage"
Pros: "Although there are baggage and carry-on fees, the price of the ticket was so affordable that it's ok."
Cons: "Website challenges - didn't seem to connect my flight to my existing frequent flier account, may need to track this and make sure we get the points."
Pros: "Thank God the flight was short!"
Cons: "Just about everything. The initial purchase of the plane tickets was what I thought was a deal. But this airline nickels and dimes you to death. We had to pay to check a bag. We had to pay for a soda. Only water is complimentry. We had to pay for the very uncomfortable seats we sat in. Really...what was the plane ticket for? By the way, if you wait to choose your seat/and check your bags...the price goes up. In the end it would have been cheaper to fly any other airlines. I'd never fly frontier again."
Cons: "Missed our connection due to delay. They offer no accommodations or options. Had to buy another flight. Will never fly frontier again."
Pros: "I missed my first flight back to Phoenix and a sipervisor rescheduled me for a later flight. She was amazing and wonderful as there were no extra charges. She also helped me with handicapped transport around the airport. The man who got me from the counter to the gate stopped at a restaurant so I could grab some food as I didn't have any time to eat during the day. However all 3 flights were pushed back with the last over 2 hours late. I didn't get home until well after 2 am. Should have gotten home by 11:30 pm. Colleen"
Pros: "That they waited for a plane to get in and take the passengers who were already booked. Between the holidays and bad weather, it was the right thing to do."
Pros: "Short flight. - But loved the price - very cost effective."
Cons: "My stay was short so I didn't need to check a carry-on or bag. Had I needed that service I would NOT have chosen Frontier - I seriously object to having to pay extra for an item that is not an "extra" - who travels without some type of luggage?? Just charge the cost up front and be transparent - it is difficult to determine exactly what your flight is going to cost you - which is exactly why I don't normally fly Frontier!"
Cons: "A completely unprofessional,disorganized and disappointing experience. I will be sure to steer everyone away from this airline in the future"
Pros: "Low prices, easy to deal with. They provided a great range of options."
Cons: "$40 per checked bag, snacks and drinks expensive. Plane seats seem so much smaller now. Every little thing is charged, including your seat."
Pros: "The seats were surprisingly comfertable! And I really enjoyed having more personal space in front of me! No other airline have seating like Frontier! I flew United in to Colorado and it really felt like sardines with Frontier I didn't and both flights where full!"
Cons: "I didn't like the surprise 40$ fee to bring carry on. I don't remember seeing that when I bought my ticket. I don't mind paying for my luggage. But would've been nice to be able to add that to my flight bill rather then having to pay the fee in order to get my flight ticket."
Pros: "Flight attendants being apologetic"
Cons: "Boarding agent was very rude and told me I could not board because of dog. Even the other passengers were appalled by his behavior and complained. on board flight attendants had to apologize for his behavior as well. He made me cry and wouldn't let me board. It was the worst flight experience I've ever had."
Pros: "Finally getting home"
Cons: "Employees were helpful"
Pros: "Made us wait 40mins on the plane for another plane and didn't have the AC on."
Pros: "Did not purchase our tickets directly from Frontier, so was confused about whether or not you had to actually purchase your seat; however, it was completely clear that there was a fee for carry-on & checked luggage. Flight attendants were very nice. Captain was not nearly as informative as he could have been. We enjoyed our trip to our destination more than our return flight due to rough take off & landing. We will definitely fly Frontier in the future."
Cons: "Unclear info. about fees. Rough take off & landing."
Cons: "It was 20 min late."
Pros: "Fly delay 3 hrs. Waiting 4 pilot . they make us wait inside plain no air conditiloner. Super hot"
Cons: "Nothing"
Pros: "I was surprised with how smooth the boarding process was, how clean the plane was, and how nice the flight attendants were."
Cons: "I bought a plane ticket and then had to pay for a seat on top of that, as well as exorbitant charges for bags, and we ended up paying far more than even the plane ticket for all the extra charges. If I buy a plane ticket, that price is what I am expecting to pay. I understand a few charges here and there, but more than double what I expected to pay is completely crooked and terrible business. The plane ride was bare bones, uncomfortable seats, and average service. We will never be flying Frontier again."
Pros: "I got to AZ safe"
Cons: "The floor had throw up all over it. It stunk. The seats are uncomfortable., tray tables too small to put a laptop much less a drink and food. arm rests make noise. It was just a filthy mess"
Pros: "I'm handicapped and the service I was given was excellent. From the moment I walked in the door at DIA I was given superb service. It made the trip so easy and pleasant. The flight attendants were also helpful when I needed a little water to some medication."
Cons: "Charging for carry on baggage is ridiculous. I was warned ahead of time so I carried a oversized purse that would accommodate a book and my ipas mini. But charging for non alcoholic beverages is highway robbery! And the food offerings were nothing but junk food. No wonder you are rated last in the airline industry for customer service."
Pros: "Boarding seemed to move really quick and seats were comfortable and seemed roomy."
Cons: "Flight was an hour late leaving. Check in at ticket counter was beyond packed, the line wrapped around."
Pros: "Flight was short"
Cons: "I was not informed that I would be forced to pay for a carry-on, which was more expensive than checking my bag. I checked it, which then forced me to have an additional 30 minute wait at baggage claim. Horrible experience especially due to the splitting headache from the child who was screaming louder than I ever thought humanly possible (that obviously wasn't the airline's fault though)."
Pros: "Crew very nice. Ticket and gate agents helpful, although a little stressed."
Cons: "Seating cramped and uncomfortable. Plane on this leg of my trip dirty - didn't want to place my purse under seat due to filthy carpet. Piece of window trim fell off during boarding; took 40 min to get maintenance to come up with roll of duct tape and make temp fix - flight delayed more than 1 hr overall."
Cons: "Flight leaving Milwaukee was delayed due to technical problems. Got on the plane an hour late, sat on the plane for over an hour, had to get off the plane and wait in the terminal for 2 hours therefore missed my connecting flight and have not arrived at my final destination. There was nothing offered for the trouble or inconenience (snacks, drinks, etc.). I had to miss an important meeting and never want to fly Frontier again."
Cons: "Baggage fees equal to ticket price"
Pros: "I liked how affordable the flight was."
Cons: "I am not a fan of charging extra for bags or drinks/snacks. I think the airline can afford to serve their guests a tiny drink. Also, the seats were uncomfortable and the tray on the back of each seat was ridiculously small."
Pros: "Good service"
Cons: "The person at the gate informed me that I would have to pay for my bag. The same bag I had just brought from Portland on the same plane. She was rude ."
Pros: "I liked getting off plane."
Cons: "They have designed seats for children."
Cons: "not able to take the carry on into the plane and paying 40$ to check it in."
Pros: "Crew was pleasant"
Cons: "By now, the thinly cushioned seats hurt"
Pros: "Clean cabin"
Cons: "Long layover in Denver was 2 1/2 hours. It just made for a very long day."
Cons: "They canceled the flight and didn't notify us! We will not every choose to fly spirit again"
Pros: "Flight left on time."
Cons: "Seats were cramped and uncomfortable. Small plane. They charge for everything!!! Will not be back."
Cons: "a $57 fee for a carry on is a bit ridiculous. If I had know this, I would have flown on a different airline for a little bit more cost."
Pros: "The crew was excellent!"
Cons: "The flight was real bumpy."
Pros: "It was not bad but it could have been a lot better"
Cons: "No one had cleaned Before we boarded. smashed crackers in the seats and all over the floor. Overpriced baggage!! Won't be flying them again!!"
Cons: "The flight attendants were nice, but Spirit makes it a pain in the neck to get your tickets. You first of all are REQUIRED to create an account with them so they can send you advertisements that you don't want cluttering up your mailbox. Second of all you have to pay an extra $10-20 if you want a seat. Furthermore, you have to pay extra for a carry-on. That's ridiculous! The flight was also delayed two hours, so I had to sit around the airport for 4 hours! When you finally board, the leg room is pathetic. I barely had room to fit my legs in with one small handbag! They also make you pay for in-flight refreshments. This is one of the worst flying experiences I have ever had. I am never flying Spirit again!"
Pros: "Not much"
Cons: "They advertise cheap fares and then charge exorbitant amounts of money for everything else. And they're elusive about it. If I hadn't read some blogs before my flight, I would have gotten ripped off even more. It's a total scam."
Pros: "The plane was clean and in good condition. The crew was professional. The flight was on time and ahead of schedule."
Cons: "This was my first flight with Spirit and I will avoid flying again with Spirit. Too many surprises with the extra expenses such as the seating charge, the baggage fees (especially the 40 pound limit on check in baggage which was new to me), the extra fees for not completing tasks online. It is just a nuisance to try to keep up with the next fee that will be sprung on the passenger. No more!"
Pros: "it was sufficient"
Cons: "charged for bag at check in."
Pros: "I like the base cost and then having the choice to add charges to my ticket designed for my needs."
Cons: "Would like to pick my seat and pay for it ahead of flight."
Pros: "Yes it was a great experience and a great price for the flight !"
Pros: "The crew was great! Flight was on time ... quick trip to PHX .. I chose it for the fare only - and may, now, again if a similar situation comes up. Good experience. I did not have bags to check as it was a quick turn (returned few hours later on SWA). So, didn't have to mess with the nickel and dime-ing for every little thing. Seats don't recline - quick flight -- didn't matter for me."
Pros: "i have flown spirit multiple times out of phoenix in all kinds of weather and not once has it ever taken off on time! once the airline attendant even yelled at the passengers upon arrival at the gate like we were all children. I decided to check the status today instead of waiting in the airport for four hours and yes--- again it was delayed one hour and then two hours. so I planed accordingly and planned to be at the airport 1.5 hours ahead of the revised flight time. then they changed the flight time again and now I've missed my flight. this airline is absolutely the worst and I have flown domestically and internationally for over 35 years. I'm done with you spirit!"
Pros: "Honestly I didn't like anything about it. The flight itself was fine but charging for everything including checking luggage, $55, and carry on's, $52, was so expensive. I don't have issues with affording flying expenses but I don't expect to pay this kind of money without being informed when I purchase my ticket. NONE of this was explained in the purchase part of the ticket. I will NEVER and I repeat NEVER fly this airline again. I fly all the time for business and family related matters and have never had this type of expenses included in my flight. I am not a frugal person but this is ridiculous. Domestic flights will be only on airlines that do not charge for these things i.e. checking bags and pretzels for Christ sake. Spirit never! Thank you. Call me Chuck Fantastic."
Pros: "The on board service was statisfactory and curious."
Cons: "For me the seats were too small. I am 6ft3in 200 slim pounds. If i could of gotten an isle seat or emberency door and picked my seat ahead of time even paid more for it would of helped. Getting to check in early does not get you a spicific seat. A child can be put in an isle seat whereas an adult can be put at the window seat slighty more cramped."
Pros: "Pilot was friendly and updated passengers of every progress of flight."
Cons: "Steep carry-on fee"
Cons: "flight was delayed but there was no announcement made.. the new time was just posted on the screen."
Pros: "Nothing"
Cons: "Where do I start? The flight was delayed 2 hours because the crew was late. Once boarded they had us sir for an hour before taking off"
Cons: "Flight from Phoenix was delayed. Takeoffs and landings were rough."
Pros: "The timetable given on my boarding pass was helpful. Arriving at airport, getting through security,etc."
Cons: "Payment for everything. Didn't feel like I was getting a great deal on cost to begin with. Was just not ready for the sarcastic tone to your flight staff. Some around me laughed at her tone others felt she was just plain rude. Just not sure this experience is something I'd do again."
Pros: "It was a smooth flight, good service and easiness of everything."
Cons: "Kind of cramped quarters on the plane"
Pros: "The flight was great"
Cons: "The fees"
Pros: "Flight on time."
Cons: "Too many add on costs after initial fee. Checked in at airport early. Went to gate and sat for 2 hours and realized the gate on my ticket had changed. No announcements at the gate as to changing gates. I had an email when I got home, that didn't do me any good. I don't have a Smart phone so can't get the email til I get home. Airline cannot assume that everyone has a smart phone. I might have missed my flight if I hadn't been paying attention. After I asked at the counter at the gate about the flight, then they made an announcement as to the moving of the gate. NOt helpful..."
Pros: "Y'all are stealing money."
Cons: "Why do I have to pay for a carry on and on top of that it's more expensive than the other bag"
Pros: "Service was great, plane was clean and roomy. The flight attendants were funny."
Cons: "No water or drinks."
Pros: "the flight attendant very funny"
Cons: "the 2 hour delay"
Cons: "I dont like how at least water isn't available without purchase. Other than that it was a good flight."
Pros: "Your ticketing agent on August 6th was absolutely rude and nasty. My 8 year olds commented about her behavior without me prompting. Otherwise, the flight was wonderful."
Cons: "I paid for window seats and got a middle seat"
Pros: "It was fine, bare bones, but it was a bare bones price. Staff pleasant."
Cons: "Would have been excellent if there was a bumper between the armrest and the metal on the chair. While waiting for takeoff with many children playing with them, the noise was awful. Yes, I know the parents should have stopped them, but maybe if they didn't make such a nice racket the kids wouldn't enjoy it quite so much."
Cons: "There was gum on my seat. That was an airline first. Moreover, It cost more for my carry-on to get where I was going than it did for me."
Pros: "Safety and crew"
Cons: "Lack of comforts and complimentary food"
Pros: "It was a good flight on time"
Cons: "I checked in on my phone the night before and took a screen shot of the boarding pass once the "print boarding pass" automatically opened. After waiting in the security line at Denver International for 25 minutes I got to the front and tried to scan my phone on the TSA machine and was informed Spirit doesn't use mobile boarding passes (the one I had saved is not able to be read by TSA machine)! I had to go all the way to the ticket counter for a paper boarding pass and almost missed my flight. It's 2016 and Spirit does not use mobile passes...so lame."
Pros: "Flight was on time and crew was friendly."
Cons: "It's how Spirit keeps their airfares so low, but a complimentary beverage and snack would be nice."
Pros: "Great seats!!! Very comfortable! Best economy seats I've been in in terms of comfort and space. Initial check in people were helpful and efficient."
Cons: "$100 to check my bag each way (it was just over the weigh limit of 50 or else it would have been $75. My bag was heavy so I get charging extra-prices just seemed a little high. Once we got to gate, the whole vibe and staff changed. Everyone just seemed stressed and grumpy and rushed. We didn't get one smile from any staff member. The positive is that when we got to gate, another flight was arriving and i figured it would take awhile but they had us back on quickly. Downside, I went to get a book and charge my phone and I heard "last call for Phoenix, doors closing" so my daughter and I grabbed our stuff and ran. When we got there, the door was open and they were letting last passenger in. We ran to door and he said "the door is closed, you can't get on. Next flight is tomorrow. I missed it." I answered, "I'm looking at the door and there is someone standing there and going in. It isn't closed." And we argued for a minute or two while someone was holding the door open that I was told was closed. I apologized for missing announcement and said "it was a very quick turnaround. I had no idea you were that fast and it is my fault...but the door is clearly not closed as I am looking at it." The gentlemen standing there holding the door open with the other passenger then closed the door and went In. He did shortly after that let us on but there wasn't one smile anywhere from gate through people we encountered on walkway to the 3 flight attendants we saw as we boarded. We ended up sitting on the ground for 45 minutes before taking off and then I never saw a flight attendant again until we got off flight. They weren't walking aisles. We didn't get a beverage for our two hour flight. They did at one point in the intercom brag about the fastest turnaround time and least in ground time of any airline. I think that goal, though, is being reached at the expense of the customer experience. And what difference does it make if we had plane back out to runway in 15 minutes if everyone was mad and stressed and then we sat for 45 minutes (maybe I'm exaggerating because I'm mad but it was at least 30). I'd prefer an extra 5 to 15 minutes if everyone seemed to be enjoying their jobs and were more concerned about the full experience and not just the record turnaround times!! I like the idea but the implementation seemed too tress ful to make it worth it."
Pros: "Everything was on time."
Cons: "Being nickle dimed for all services."
Pros: "Nothing"
Cons: "They charged $110 for golf clubs and a small suitcase. My flight was going to be on time but the decided to give that plane to the people heading to Vegas because they had been delayed all morning. Spirit told us we would be delayed four hours, then 30 minutes later they said the flight was completely cancelled. I had to go back to the main terminal to pick up my bags and had to go to the Spirit Airlines ticket counter to rebook and get a refund. The line was so long and slow it would have taken hours to talk to someone from Spirit. I called Customer Service and was on hold for 50 minutes before I could finally get refunded. This made me miss the last Spring Training game in AZ! I've been flying for 35 years and this was the worst flying experience in my life!"
Pros: "Nothing. Flight was cancelled. That was just the beginning of a travel nightmare. I can't believe Kayak compromises their reputation by representing a shoddy, sham of a business like Spirit."
Cons: "Cancelled flight at the very last minute because of lack of crew. Not enough staff to accommodate travellers trying to rebook flights. Inept and apathetic staff who were obviously resigned to the fact that Spirit is a substandard airline There was miscommunication and lack of communication in organizing travelers which caused multiple altercations between upset travelers. It was a very disturbing experience. My rebooking took an hour because the staff member didn't know how to rebook! The 'Supervisor' who was at the next desk, was SLOWLY checking bags for other customers and did not help AT ALL. I suggested that he switch places with my agent. He ignored me competely. Attempts to call Spirit resulted in multiple auto transfers and ultimately an intentional auto cut off. I was rebooked on United. When I checked in at their desk, they told me that all the other transferred Spirit customers before me had been sent back to the Spirit Desk because their transfers had not gone through. I have been warned about Spirit. Now I would warn anyone considering Spirit. If it goes right, you're ok. If not, get ready for a travel nightmare. No one needs this kind of abuse."
Pros: "The stewards were very pleasant. It was easy to board."
Cons: "Had to pay for snacks...So I didn't have any. And your carry on prices are outrageous. Actually the bag charges all around were a bit excessive."
Pros: "2 of the flight attendants had a good sense of humor."
Cons: "Flying from Denver to Phoenix, our flight was delayed by 2 hours due to problems with the sanitation system. Flying back home, our flight was delayed 3 hours due to electrical problems! It appears to me they do not keep up with regular mtce. on their planes, as that seems extremely poor. This was the first and LAST time I will fly on Spirit."
Cons: "3 1/2 hours late taking off. I would not use Spirit Airlines if I had to be somewhere on time."
Pros: "Cheap fares but then lost all my money because they weren't helpful."
Cons: "Security took too long and spirit doesn't have mobile boarding passes so I missed my flight. Then after I ran to the spirit counter they didn't offer my a voucher for another flight nor a refund. They said they could move my flight to the next day or do nothing. I fly a lot and have never ran into this problem before. Don't bother trying to call their "customer service" phone number either because it's the wrong number, then you will be redirected to an answering service that doesn't work, then placed on hold for 20+ minutes, followed up by a service rep who isn't helpful and doesn give you any answers."
Cons: "Flight was delayed"
Cons: "The flight was delayed both ways 3 hours. On a 3 day get away we spent 2 of them sitting in the airport. Will never fly spirit again."
Pros: "Flight was good."
Cons: "I did not like the extremely high bag prices and seat prices - outrageous. I have always assumed that when you buy a ticket it entitles you to a seat on the plane. I guess not any more. I had to pay $14 each way. That is just wrong!!! There were a few free seats, but very few and they were taken.. This airline brags about their low ticket prices. They are much higher when you add all the other charges in. I will not travel on this airline again. It is sad how everything is all about gouging the customer for as much money as they can."
Pros: "nothing"
Cons: "I paid more in bag fees than for the flight. Fraudulent!"
Cons: "Tickets are cheap but airline doesn't tell you of all the hidden fees like luggage fee seats etc. Plane had several empty seats yet flight attended didn't let people switch seats."
Pros: "We arrived on time and safely."
Cons: "The check in baggage is now 40 pounds max, carry ons you are charged for, the seats don't lean back, advertising posters were located inside the cabin."
