Cons: "Basic Economy tickets are a joke. They are no savings for customers just added restrictions and an overall unenjoyable flight experience as you are being surveillanced by every United associate to ensure you pay for a carry on bag. United and Spirit airlines are now one in the same. United hasn’t suddenly introduced lower fares than before, but rather is reducing the benefits that come with the most basic fares."

Cons: "The seats felt stiff"

Cons: "I do not like those head rests.. I wish the were detachable."

Pros: "Seat too small, zero entertainment, minimal food"

Cons: "I was seated in a window seat and another woman my size about 110 pounds was seated in the aisle however there was a 400+ pound man sitting in a middle seat which made it very difficult for me especially to even sit back because it was touching me the whole time when you have somebody of that size You should make sure they are on and I'll because then the find attendance would have some difficulty getting through instead of your passengers being inconvenienced either that or force people of that size to take two seats"

Pros: "The service was good"

Pros: "Glad you didn't give priority to those with other designations like priority plus etc"

Cons: "Plane late leaving Chicago due to no pilot."

Pros: "Aisle seat."
Cons: "They made my dad check his bag even though there was space."

Cons: "I was informed today that one of my checked bags was picked up by another customer who eventually realized it was not her bag. She brought it back to the airport and refused to turn over the bag until the airport compensated her. (How this happened I have no idea because I stood right by the entrance of the baggage claim and never saw the bag come out). The customer refused to return the bag until the police became involved at which point she agreed to write a note confirmed she did not steal anything. The bag then needs to be sent to me in 2 days and I'll have to verify myself that indeed nothing was taken from the bag. I'm very concerned how this individual came to be in possession of my bag considering, again, I stood right at the entrance of the baggage claim conveyor belt from the time it started to when it ended. As a result, this experience really made me feel frustrated and violated."

Pros: "I got there on time"
Cons: "Why not have people board the plane based on sat number? Why this cattle call and stand in line like you're not going to get a seat? Everyone fighting for line position so they can get a place in the overhead bins? Stupid."

Cons: "Need plugs my phone died on the flight"

Cons: "Check in"

Pros: "Complimentary something! Entertainment options would be nice."
Cons: "No complimentary anything! No entertainment:("

Pros: "The only thing I liked was that Frontier didn't wait until the last minute to tell us the flight was delayed (twice)"
Cons: "Everything else. There was no food. The seats did not recline (confirmed by flight attendant), no entertainment, baggage claim took over 45 minutes. The tickets were not that cheap, especially after being nickel-and-dimed for every little thing. But for zero amenities I would hope they would at leas"

Pros: "Nothing"
Cons: "Delays, gate changes, lack of notification, last minute changes."

Pros: "Arrived 30 min early"

Pros: "Quick flight."
Cons: "The seats don't go back, but you get what you pay for last minute."

Cons: "Flight was extremely late departing"

Cons: "not clean"

Cons: "They didn't tell us they stop issuing tickets 45 minutes before departure."

Cons: "No lo vuelvo a usar, el cobro de la maleta es un robo, las demas aerolínea cobran 25 y frontier 40 es demasiado la diferencia y el valor del tk es costoso"

Pros: "Bag charged"

Cons: "Worst customer service, will not book this airline anymore."

Cons: "The flight was cancelled for nor reason. At the front desk suggested me to call. I've been trying to call for weeks, with no luck."

Pros: "It was canceled without any post notice. I will.not use frontier next time."

Pros: "The pilot got us to our destination safely. Attendants were friendly. The flight itself was late, no drinks, no tv, seats do not recline."

Pros: "over all everything was good"
Cons: "nothing"

Pros: "Great pricing no delays and quick. Great staff. Early on both times there and back."
Cons: "Nothing"

Pros: "On time"
Cons: "Very bad seats"

Pros: "The crew was awesome. They were very understanding and flexible to sitting arrangements as long as you were within your zone."
Cons: "Didn't like the idea of having to pay for a carryon. Really don't like the idea of having to pay to sit by my husband. I would definitely never fly again unless I'm traveling alone for a one day trip. This airline only seems to cater to the business traveler, not leisure."

Pros: "The flight was on time, and actually arrived about a half hour early. The crew was very attentive. Yeah, you have to pay for everything including carry-on, but if you do your homework then you know what bags you can take without having to pay the fee. If I'm traveling on a budget then I would definitely take Frontier again."
Cons: "The chairs were very uncomfortable making sleeping impossible and sometimes painful, but I can't really expect luxury for a flight that cost me $115."

Pros: "Attendants were friendly, plane was clean, and the experience was overall great."
Cons: "It would have been nice if the plane carried wifi or some kind of tv/music option for entertainment."

Pros: "Loved the price and the crew was excellent! We were on time and had a great flight . I am perfectly happy bringing my own snacks !"

Cons: "They lost my baggage..."

Pros: "Took off and landed"
Cons: "Really? Seats that don't recline? Please?! $40 for a carry-on? Need I say any more? Filing this airline with Spirit as a last resort... $100 below buffer"

Cons: "there were too many delays and the situation was handled poorly. I do not plan to fly Frontier again in the future."

Pros: "Nothing"
Cons: "Front desk people were very rude and charge me $45 for a carry on bag"

Pros: "Cheap"
Cons: "Arriving at O'Hare to take this Frontier Flight.. there was a line a mile long for Frontier Airlines. They created a mess and did not try to assist those of us in line. The line was to check in bags. There were 3 different flights, and it was so unorganized. I realized after an hour that I didn't need to be in this line. I had paid for a carry on, thank goodness otherwise I would have missed this flight, like many did behind me. The flight attendants were rude! I needed to purchase a drink to take some medication, and they made me wait. It was ridiculous."

Pros: "Quick boarding"
Cons: "Terrible seats"

Cons: "Horrible fight."

Pros: "On board crew was very nice and were very entertaining."
Cons: "I've flown frontier before and I have never had a problem. Tried to check in for our flight 30min before it took off as we were running late. The rep who was working the desk (young female, approx. 20yrs old) gave us the worst guest service I have ever received. I did not understand why we could not check in, nor attempt to board our flight, although I understood it is our fault for running late. We did not need to check any bags as we were carrying them on. The woman behind the desk only kept saying you missed your flight and was very disrespectful when our friend tried to talk to her saying "I don't know why your even trying to talk to me, I told you I am done with you." I work in the guest service industry and have never been treated or talked to with such disrespect. I would have understood if she was apologetic and explained to us WHY we could not board or make our flight, compared to being rude and rolling her eyes constantly. I will not be flying frontier again I can avoid it."

Pros: "Boarding in Miami was extremely painless and easy."
Cons: "In Chicago, Monday 4/4, we were running late and the young lady at the bag check was extremely rude to my wife. In so much as to have her co-worker step in and tell her rude co-worker to stop talking. This 15 minute interaction has caused us not to fly Frontier again."

Cons: "The staff does not offer water on a 3 hour flight. Even bringing a carry on for the overhead bin is an extra fee. The website deceives you into paying more for seating."

Pros: "No problems went very well"
Cons: "Nothing bad to say"

Pros: "I liked boarding first because I had a carry on. Easier to lug it up into the overhead compartment without the potential of hitting someone in the head. The crew was very friendly."
Cons: "The seats have no padding. Comfort comes at a price I suppose."

Cons: "Uncomfortable seats. Leg room gets tighter every year lots of extra charges"

Pros: "The cost efficiency of the ticket"
Cons: "The fact that check in at counter was denied for showing up a minute or two at the counter. Wasted finances."

Cons: "Seats didnt recline."

Pros: "The crew was courteous and professional."
Cons: "After adding up all of the hidden fees with the "low cost" of the flight, it all came out to MORE than I would have paid if I had booked a flight with another carrier!. As ad DEPENDENT of an active duty military member, I NEVER have to pay for checked luggage, much less a carry on! Once I got over having to pay and additional $150 for luggage, I board the plane to find extremely uncomfortable seats with half of a tray table, all I could do was laugh. The joke was totally on me!!!! For a flight that was over 3 hours long, it was NOT WORTH ANY OF IT!!! I didn't do the research that I should have, and that is totally on me. Fool me once, but NEVER AGAIN."

Pros: "Nothing"
Cons: "I was locked out of the first flight due to not having the ability to get a boarding pass via the internet. When I arrived, I used the kiosk to get a boarding pass. Was directed to the ticket agent who stated I was too late to get a boarding pas. I asked if there was room on the flight and was told there was a lot of room. This was 1/2 hour before the doors closed for this flight. The agent told be to go elsewhere and that if I were to get to Miami I needed to book through another airline. I found American had a flight that left half an hour later and booked it at an additional expense of $493.10 FYI: I did have flight insurance and was told it is no good and that basically I'm screwed. I hope someone reads this and compensates me for my added expense."

Pros: "I liked the professionalism of the crew...the boarding quickness, and the cleanliness of the aircraft."
Cons: "What I didn't like, is what I don't like on any airline, and something that will never change...is the crowded cabins...the less comfortable seats that no longer recline, and, the fees for baggage, both checked and carry on's. When posting the seat fees, why not also include what the "average" cost will be, say, for two, with checking one bag, and having two carry-ons? This would make budgeting a couples trip, much easier to figure."

Pros: "I liked how punctual the airline boarded."
Cons: "The seating on the plane was very uncomfortable. The seats do not recline, and being that I was on a 6:30 A.M. flight, not having this feature to rest, made the flight very uncomfortable. I do not plan to use Frontier airlines for an early flight or for a flight that is three or more hours."

Pros: "Cheap tickets."
Cons: "You have to pay almost as much for your bags and seat selection as the tickets. Seats are hard as a rock and really jammed together."

Pros: "Customer service does not exist.i iwill never fly again with you or any of your affiliates. Don't bother w a response unless you're offering me a free flight. Good luck, you will need it if you want to remain in business, Sincerely, Lee Arroyo"

Cons: "Delay of two hours"

Cons: "1- solamente daban agua en un viaje de 5 horas 2-la comodidad terrible los acuentos parecian de bus de carretera ... Bueno el avion decia airbus pienso que esta aerolinia no esta capacitada de ningun modo para hacer viajes mas largo de 1 hora 3- de regreso las vegas miami nunca me ofrecieron ni agua 4-los acientos no se podian ni reclinar tan si quiera mi novio tiene los pies grandes y tuvo que ir doblado todo el tiempo ... Entre mucho mas no recomiendo esta aerolinia es barata pero lo barato sale caro gracias!!!!"

Pros: "My name is Yacouba, On the day of the flight I had to return a rental car in a city that I am not familiar with. Therefore, doing so took a little long than expected. I happened to miss the flight. At the checkin, instead of putting me on another flight, they told me that it was over that I had to rebook a new tickets to my own expense. I thought that was not fair enough from an airline."

Cons: "My flight was cancelled at the last minute forcing me to look for another flight and ending up buying a very, expensive, last minute ticket on United Airline. I could not accept the flight on December 31, 2015 due to many very important meetings. I hope that this will not happen again."

Pros: "All around good experience. Easy boarding. Ample accommodation on flight. Paying for carry on allows you to be first group on the plane so that has its perks. Felt like the old days two decades ago when flying wasn't so complex. Had read bad reviews of the airline overall and found none of it to be relevant. For the price the experience was just as good as any other airline that boasts good service - "high level and high price". Don't be scared by the reviews online. Spirit is perfectly good."

Pros: "I appreciated that they got the basics right - flight left and took off on time, my bag didn’t get lost, and we arrived safely"
Cons: "I hated being nickled and dimed. Had I realized that I would be charged $45 for a checked bag and $3 for a can of soda when I was booking my ticket, I would have chosen another airline."

Pros: "The worst experience traveling by far"
Cons: "It felt like they had a personal vendetta"

Cons: "PURE HELL"

Cons: "they charged $52 for 1 baggage then $55 if overweight. That is a rip off. Never again."

Pros: "Everyone was so friendly and helpful"
Cons: "That I couldn't take all the friendly and helpful people home with me...to make them a proper meal"

Cons: "I cannot believe I had to take this flight. Spirit prides itself as the cheapest flight, well that's because they charge you for everything else! $14 for a seat, $47 for a checked bag, $42 for a carry-on bag. After I refused to pay those fees, they told me I wasn't able to get a refund on my flight. I will never take Spirit again. My flight with Jetblue was a breeze and they even gave free snacks and drinks. DON'T TAKE SPIRIT!"

Cons: "they put us on the plane and then took us off after about one hour and then about a hour after that they put us back on and taxied out and we sat for about hour and they brought us back to gate and told us they cancelled the flight so we all had to stand in line to get a refund and find another flight we got a southwest flight and got there around 12;30 and when we got to my son's house our clothes were so wet they keep the suite cases out in the rain"

Cons: "The counter staff are rude and incompetent."

Pros: "All"
Cons: "Nothing"

Pros: "Friendly and helpful staff."
Cons: "Baggage fee."

Pros: "There was a delay, but the pilot made up some time."
Cons: "paying for a bag"

Pros: "nothing"
Cons: "cancelled flight-have yet to receive refund for bags and seat selection, had to pay inflated prices to book flight home"

Cons: "They left my ten year old son at the gate....... Nothing done....... Awful"

Cons: "Baggage policy"

Pros: "Nothing"
Cons: "Highway robbery charges for baggage, hours long delays, boarded us, had is deplane and reboard before finally taking off. Service sucks. Never ever ever again"

Cons: "That was a very bad landing"

Pros: "Delayed flight"

Pros: "On time"
Cons: "Bit confused"

Pros: "Nothing"
Cons: "Worst experience ever."

Pros: "Very entertaining flight crew!"

Pros: "Cheap and on time"
Cons: "There is no app to check in and if you don't print your boarding pass ahead of time, they charge you $10"

Cons: "Add-on costs piling up. The only thing left free was the cost to breathe."

Pros: "The pilot was good. The crew was pleasant."
Cons: "The seating is pathetic. Way too little space. Also, Spirit nickels and dimes its passengers to death."

Pros: "The crew on the return trip were friendly and funny."
Cons: "I found out about the $45 carry on bag fee for each flight with the email check-in notification. This meant my short trip bos-ord was $90 more than I thought. I could have flown on a real airline like JetBlue or American for that price. Kayak needs to tell people that. it's not a true comparison when searching for low fares."

Pros: "I like they're trying to disaggregate costs -- but this ends up feeling like punishment."
Cons: "There is a lengthly upsell process which is part of printing your boarding pass and checking luggage. - they charge of 'carry ons', so I paid for the shoulder bag for my computer along with two regular bags....both ways. (note this fee was nearly twice my ticket fee.) - When I arrived and the gate and staff said people make this mistake a lot, there was no way to get a refund other than a time limited credit. - Though this will change, they currently don't allow TSA Pre customers to use that status. They also dont have wifi, a huge business advantage. - When I arrived 30 minutes before the flight, they refused to issue a boarding pass, couldn't transfer me to a same day flight, or refund any portion of my unused tickets or prepaid checked bag fees. Note: I walked to the American Airline counter, bought a ticket, checked bags, and left 30 minutes later -- with more hospitable treatment and only slightlyl higher total cost. I like trying new business approaches -- but I've flown four of their flights and now have the resolution to avoid them at most any cost."

Cons: "I had to print out the ticket at a kiosk even though i checked in online and also the staff at the check in desk had terrible customer skills, did not smile and did not seem to want to help you. i was called ON my way to the airport (couple hours before departure) that my flight was canceled because of air traffic congestion and was told i could be switched to the next flight the next day which was not acceptable in my situation. I stood in a long line to get a refund and also the flight into Chicago via Spirit was unsettling especially because all staff over the intercom inside the airplane including the pilot did not have their lines memorized and kept stuttering because they messed up."

Pros: "Nothing"
Cons: "Cramped seating"

Pros: "I liked the low ticket price"
Cons: "Spirit's model is "No frills" which means you have to pay additional $$ for EVERYTHING besides your seat: carry on, checked baggage, food, drinks, etc etc. Someone even had to pay extra to print their boarding pass at the counter (they missed that you have to use the kiosks first). If you are going to actually benefit from low ticket prices you have to be traveling really light and maybe sure you pay for your luggage in advance online. Lines were long, service was slow, and they lost my luggage and never called me when it was finally found. Then they were saying i had to pay to get it delivered, until i proved that i hadn't checked in late to my flight (thankfully my kiosk check-in time was in their system). All around negative experience."

Pros: "I've never flown spirit before, and knowing they are a no frills flight, I was sketical that I would have a positive experience. the plane was comfortable and clean, the crew was super friendly, and the price can't be beat!. I wish I could say the same things about my United flight back home. Overall, I was pleasantly surprised with Spriit and would totally fly with them again."
Cons: "They need to invest in a mobile app. Not having one makes me question how serious they are about the customers."

Pros: "Cheap"
Cons: "You can't check in in advance, I was unable to check in with the kiosk, and had to wait over an hour as representatives were not helping any customers. When I finally managed to check in, they told me to hurry, as my flight was in 25 minutes. I ran through security and literally ran to the terminal without shoes on to find out the flight had been delayed the whole time with no warning or norice."

Pros: "Nothing at all!"
Cons: "I did not like the fact that the phone adviser told me I was allowed two bags, but neglected to inform me that I needed to pay for the bags. On top of that, The flight was delayed and they people at the boarding station were extremely rude. I would not suggest Spirit Airlines to anyone. It does not save you money."

Pros: "Nothing.."
Cons: "The staff was unhelpful and rude. They gave me a ticket for the wrong city after I said twice "Portland MAINE" not Portland Oregon. Ended up getting the wrong one. This was after my original flight to Boston had been canceled after being delayed 3 times. I was supposed to leave Chicago for Boston at 2 pm. Didn't leave until 8:30pm. As usual I got to the airport two hours early so I spent 8 hours in the airport of the city I was trying to leave. Trying to get a new flight and eventually just got a refund for about half my original ticket and buying a new ticket on another airline. They were rude the whole time and unhelpful. But that's just airports. But the lady giving me the wrong ticket is ridiculous. This review is silly because eventually I got on a JetBlu flight anyway. I never ended up taking Spirit anyway. I still have my return flight booked so lets hope I make it back home on time..."

Cons: "The flight was delayed for multiple hours until it was cancelled because too many flights were trying to leave at once, basically had they not delayed it wouldn't have been an issue. My friend and I had to be home that night to pack and be ready for a trip to South Africa early Wednesday morning. So due to waiting for spirit to cancel we almost missed the last flights to Boston that night from other airlines and we're lucky enough to just make it onto one from the standby list."

Pros: "That they cancelled the flight and didn't rebook me until the next day"

Cons: "Delayed 2.5 hours and missed my bus to cape cod. Ruined my whole weekend."

Pros: "It was cheap and I got to where I needed to be on time."
Cons: "The bag check-in line at O'Hare was ABSURDLY long, and not because of anything the passengers were doing. There were several workers behind the counter but most of them were chatting rather than actually bothering to check their bags. My flight nearly closed their baggage check-in (45 minutes before departure) by the time I made it to the front."

Pros: "Nothing"
Cons: "Flight cancelled . Nothing handled well. S**ked"

Cons: "Got an email on the way to the airport notifying the flight was canceled. Notified only 2 1/2 hours before flight so not much to reschedule. Had to rebook on different airline."

Pros: "Nothing much"
Cons: "Paying my small luggage for 45 dollars"

Cons: "The flight was cancelled in the last minute - For our plans it was a disaster. It was a big demage"

Pros: "Plane was new and they had cold beer that wasn't over priced"
Cons: "Spirit loves to tout "unbundled" fares, but a lot of that is just a way to hide the true cost of flying (versus paying upfront with a regular airline). We chose Spirit thinking we would save ~$100/ticket, but after bags and a decent seat we ended up in a plane with no TV's and poor check in (No Pre-Check capability?!?)"

Pros: "Boarding was very organized and on time, the flight experience had no problems, and I believe we even landed a little than before scheduled. All in all a very smooth travel experience."
Cons: "There isn't anything I had a problem with at all!"

Cons: "The flight was an hour delayed even though the plane had come in on time from the earlier flight. No information was ever given as to why we were delayed."

Cons: "My bag was lost and the people who work there are incompetent"

Pros: "Absolutely nothing"
Cons: "Delayed 3 hours. Didnt have a co pilot. Took forever to retrieve luggage and it was not clear where it was to be picked up. Overall a terrible expereince and eveytime i fly spirit this seems to happen. Will never fly with spirit again. Had a miserable day."

Pros: "Seats were comfortable"
Cons: "It is absurd to charge 55 bucks for a carry on!! Also ridiculous there is no beverage service"

Pros: "crew was polite."
Cons: "Paying for seats at check in. That was a surprise. There was NO leg room. There was no beverage/snack offered. Could at least offer water and peanuts."

Pros: "Hadn't flown Spirit in years, and I was very satisfied with them."

Pros: "Inexpensive"
Cons: "Very cramped. No reclining. This is the city bus of airlines."
