Scores according to KAYAK customer reviews

Pros: "The crew/pilot was excellent he got us an hour prior to schedule, however, the stewardess did not have good training to lay down rules i.e. going bathroom. They can be stricted but nice."
Cons: "Food not snacks should be an option to purchase."
Pros: "Crew was very nice."

Cons: "Paying $3.00 for a $.50 soda, paying for carry on bag. very uncomfortable seats, no entertainment at all for such a long flight. need I go on?"
Pros: "It gets you from point A to point B."
Cons: "By the time you add a bag, you can fly another airline. And if you're over 6', it's not worth it. I'm 6'4", and my knees touched the seat in front of me for the whole flight. Seats don't recline, so I couldn't adjust at all."
Pros: "Good flight. Accommodating. Will fly again. Cheap flights"
Cons: "Why should anyone want to book a flight only to find out that the ticket price doesnt include a seat................. for a seat there's an additional charge. And then a charge for a carry on bag of $40. Your airline is ridiculous!"
Pros: "I'm 6'3" and simply cannot get comfortable in a plane seat."
Cons: "First of I got double charged for my bags second flight delayed for no reason n seats are extremely uncomfortable we arrived n we stuck in the airport for 30 mins no reason bags took an entire hr so I just left my bag"
Pros: "seats were some what comfortable"
Cons: "did not like the fact that I had to pay extra for a seat when I already purchased a ticket"
Pros: "Getting off the plane."
Cons: "Frontier is all around archaic in a modern world."
Pros: "not much"
Cons: "fees for everything, new plane but hard seats, no screen, tiny useless tray tables, and flight was 2 1/2 hours late. the fees were the worst part, however -- next time I'll factor in an extra 100 bucks per ticket when I'm comparing prices to cover all the fees."
Pros: "The flight was cheap"
Cons: "Flight delayed 3 hours due to technical difficulties. Was forces to pay to check my carry-on because it was considered a "duffle bag". Screaming children the entire return flight not even seated. Cramped quarters. Terrible"
Cons: "They cancelled my flight. Soonest Frontier flight they could re-book me on was EIGHT DAYS LATER. They have no agreements with other airlines to book cancelled passengers with. They would NOT pay any hotel expenses. It was left to me to find alternate transportation home as well as book a hotel room for the night and pay for it. This was the absolute worst airline I have ever flown on in all my years of air travel. Did I mention that they even charge for the in-flight soft drink? Oh yeah, The seats don't recline, none of them."
Cons: "Seating because the seats don't recline and the leg space was basically non existent. First experience on Frontier and unless they make changes for some kind of comfort then this is definitely our last!"
Pros: "cheap fare"
Cons: "The new seats were very uncomfortable for such a long trip. Too close together. BTW I'm 5'1" and weigh 100 lbs. paying for a very limited choice of unhealthy snacks"
Pros: "Really appreciate the free check baggage for military. The fares are good."
Cons: "The airline charges for everything except water. Seats do not recline at all."
Cons: "The seats are extremely uncomfortable."
Pros: "Easy check-in & baggage drop"
Cons: "Seats were stiff and did not recline No neck support for snoozing ..."
Cons: "The seats didn't recline"
Pros: "There's nothing bad about Frontier's service. Flights were on time, staff was courteous."
Cons: "BUT, they don't honor Global Entry or TSA Pre-Check, which is ridiculous! The ticketing agent told me "it's not in the budget." Had I known this ahead of time I wouldn't have purchased a ticket from Frontier. The security lines were incredibly long in Denver and this added a good 30 minutes to my passage through the airport."
Pros: "I didn't have to pay extra for my seat with extra leg room"
Cons: "There was confusion about my seat"
Pros: "Arrived early"
Cons: "Had to pay for seating"
Pros: "Crew was great"
Cons: "Small seating"
Pros: "Staff were friendly."
Cons: "The seats are very uncomfortable and cannot recline. I was unaware while booking that they would charge for the carry-on. What is worst is that carry-on was more expensive than checking in a bag. I now understand that it is a budget airline, however, once you include the fee for the carry-on/check-in bag it is no longer a good price for the flight."
Pros: "Cheap cheap cheap flights even with paying for a checked bag our total round trip for 2 people was less than $160. We knew frontier was a bare bones plane ride. We had no issues with everything. The seats were a little uncomfortable and the trays were about the size of a check book but other than that the flight was fine."
Pros: "Flight crew were nice."
Cons: "Seats are so uncomfortable in both airplanes I went on, there's no food given to you noy even complimentary peanuts or water . No entertainment at all? Did I mention that the seats were horrible and my back hurts now I'm never flying with Them again !"
Cons: "I attempted to contact the airline for over 12 hours and they had no customer support during winter storm flight cancellation. I guess you get what you pay for, so i would expect zero fare for future flights to go along with zero assistance from the airline."
Cons: "I'm not happy that I wasn't notified in advance that there would be an added $40 per bag. When flying with other airlines usually one bag and carry on is included in the price. I am not happy that upon arival I was notified my one bag would be an extra $40. That should have been discussed before."
Pros: "The flights were on time and bordered quickly"
Cons: "Very little leg room and seats don't recline. Everything is very basic, no comfort features. The fee for a just a carry on item was surprisingly expensive!"
Pros: "That we flew."
Cons: "They lost all the oversized bags and its impossible to find someone to help you. Once we did, they had no idea where anything was and yet the bags were put on the next plane. Where's the communication? If Frontier in Denver knew they screwed up, wouldn't they call SAN to give them the heads up? Late at night, families w small children, wait more than an hour for a carseat that isnt coming only to wait in another line to claim its lost. This if course all after a long flight. Awful. ...and I didn't get a refund for the bag."
Pros: "The crew on every flight was friendly, helpful and even some of them funny."
Cons: "Frontier's decision to nickel and dime everything. To have to pay to choose one's seat ahead of time? To pay for a carry on, for even something to combat the dehydration that happens on flights, is annoying and I won't fly this airline again."
Cons: "Did not have any food or drink"
Cons: "No help from ANYONE from this airline!!!!!!!!!!!!!!!!!!!!!!!! What's wrong with you people??????????????????"
Cons: "I had the flight from San Diego to Denver then we stopped at Las Vegas because of some who had heart attack. I had a meeting at that day I couldn't attend because we were at the airport of Las Vegas from 9 to 2 pm looking for a flight going to Washington DC. They found a flight from Vegas to Denver then to DC but they lay over is 15 hours in Denver and I couldn't wait because I had an appointment for my dad in the next day in the morning for dialysis. So I had to reserve another flight from Vegas to Baltimore directly. And I paid that. Also, there was a lady who checked in the luggage in San Diego. When I was checking in my luggage she told me to pay 30 dollars for my bag while there was another family after me and she didn't get any money from them for their luggage and she checked their luggage for a free. This UNFAIR and impolite. So I need all of my money back also the difference that I paid for the new ticket and luggage. Thanks Wafa"
Cons: "they cancelled the fligh on me - over booked"
Pros: "The crew are nice people, and it got me from Denver to San Diego and back. Relatively inexpensive."
Cons: "I'm tall (6'4"), there's no leg room, and the head rests aren't actually tall enough for me to sleep on. So, not super comfortable. I didn't expect anything more really. It just sucks that air travel forces premium prices for basic comfort."
Cons: "Crew was not very friendly, seats are not comfortable, and baggage is too expensive."
Cons: "Frontier is the worst airline ever. Make it look like a cheaper fare but charge you for every possible thing they can. Your seat, drinks and even your damn carry on bag. NEVER AGAIN."
Pros: "The handle on my suitcase was broken sometime between check-in in San Diego and arrival in Madison. Agent didn't know how to file a claim. Later supervisor took over as nd told me that "handles and zippers are not covered for damage." She held up a paper and told me it was in the fine print. The least they could have done was at least refund the $40.00 baggage fee. Bad news poor training . Easy fix but they missed it Joel A."
Cons: "The crew on the ground in Denver were not able to get the walkway up to the plane for at least 20 minutes after we landed. The luggage was really slow too. left the airport 50 min after the plane landed and was at the gate. Online there was no option for not purchasing a seat at check in. Deceptive pricing and policies. I did not know it was an option to not pay extra for a seat."
Cons: "Ridiculous amount of room,so cramped. You used to do well, costs for baggage too high...1 hour late start...on time commercials are false. Will not fly frontier anymore. Very disappointed!"
Pros: "I would like a free snack and drink. The stewardess passed over me when asking for a drink."
Cons: "We had to pay for a drink."
Pros: "The flights were short and the passengers were nice."
Cons: "I understand that Frontier is trying to minimize flight price by charging independantly for everything, but they take it to the extreme. Charging for a carry-on and choice of seat (including a middle seat) is a bit ridiculous. The plane seats were not comfortable and did not recline. I would not recommend Frontier to anyone because the flight price plus the add-ons did not make Frontier any cheaper than a comfortable airline."
Pros: "The staff was very nice/pleasant."
Pros: "Customer service during flight check-in was great, quick, friendly and efficient"
Cons: "Overall attitude of main female flight attendant, simply condescending and overall rude."
Pros: "The friendly crews"
Cons: "They charge extra for.carrying a small bag on board"
Pros: "The seat I requested was the seat I got; so I paid the extra $40 for the luggage to arrive with me ; it was an OVERNIGHT."
Cons: "Since I had a 3rd row seat, (3D) the seat infront pushed into my lap all night. The child seat badge said, 17 C, but at the last minute before the door closed; the flight attendant put the child in the empty seat next to me. I often had to help the child with the lights, seat buckle NO PROBLEM. However, she eat, ask for water, ask to go put on pajamas, ask to go to the bathroom, sat with 3 items , neck rest, blanket, backpack all between the seats, then proceeded to slouch down on the items as if to stretch like a recliner. The constant moaning, turning the fan on, grunting too hot, humming, just overall complaint while other; were TRYING TO SLEEP in quiet. If the child is to left in a seat , the attendance should make certain that she is not in need of things ; constantly giving her water to GO TO THE BATHROOM x 6 or 7 times in 5 hours. She really should have a designated seat close to the front and the isle. People pay to travel not babysit. That was really unfair to myself and the person around her. NO WILL NOT FLY WITH SPIRIT AGAIN."
Pros: "It with smooth and without delay"
Cons: "The seat are a bit tight"
Cons: "Everything from check in to arrival HORRIBLE"
Pros: "The plane was brand new and very clean and spacious. The flight was also so cheap. The negatives are that the seats don’t recline, there is no Wi-Fi on the plane or option to even purchase Wi-Fi, there was no entertainment, and because of the low prices, not even the water is complementary. Excellent value"
Pros: "Very roomie seats"
Cons: "Always late"
Pros: "The low price!"
Cons: "nothing really"
Pros: "Boading and time"
Cons: "Not comfortable at all the seats and the food wasnt good"
Pros: "You just have to budget in about $100 for carryon round trip + seat assignment. It's not false advertising but you really need to be aware. This is similar to WOW on which I also had a good experience. The price of my round-trip flight to San Diego came to $350 not $218 as advertised; this was still a much better price than United $660 one-way. Spirit was fine for comfort and service, I have no complaints."
Cons: "I still prefer Southwest which has exceptional service and is usually a bit roomier."
Pros: "Cheap base fare and I only pay for what I actually need!"
Cons: "Seats are too small and uncomfortable"
Pros: "I had a small bag with me & they charged $57 just to Carry it with me on the plane ,i was very surprised .each way"
Pros: "Easy boarding. No delays. Friendly crew. I'd fly again for a short flight."
Cons: "Seats aren't very comfortable and they don't recline. No complimentary beverages."
Cons: "Excellent flight"
Pros: "They were hesitant to book me on another airline, but I flew Alaskan Airlines back."
Cons: "I'll never fly Spirit again. They sent me three emails about the flight being delayed TO San Diego and then boarded ON TIME. They didn't want to let me on the plane, even though they never paged me nor did they change the departure screen in BWI. I kept knocking on the door while the stewards looked at me while they were on their phone, dismissing my plea to be on the plane. The plane left an HOUR late... but wait! The lady at the counter was going to rebook my flight and then someone called and told her they needed to let me on the plane because they hadn't even refueled yet. So she begrudgingly let me on the plane... but wait! She forgot to scan my boarding card, so do you know what that means? I was MIA on that flight. Not only did they not have a record of me on the flight (thankfully nothing tragic happened), but they canceled my return flight from SAN to BWI. So after a lengthy phone call to get rebooked, they delayed this flight twice and then just canceled it. I had to go to the counter and beg to be put on another flight. And then they offered me a $50 flight credit. For what? Because I want to fly Spirit again? Um. No."
Pros: "You didn't lose my bag this time and the flight was on time."
Cons: "it was louder than expected for an overnight flight."
Cons: "They advertise a cheap fare but charge you for everything! If you don't do it only they charge you more. The seats on the plane are uncomfortBle and do not recline! After it was all said and done this flight wasn't cheaper than anyone else. I will not fly Spirit again."
Cons: "Worst seat I've had! Very rude attendants, after charging me and my colleague 130 Dollars for our backpacks(!?), I was trying to make a joke with the attendant and asked her if it at least comes with a smile. She told me no ( very seriously) and that that's an extra charge. Then she started telling me about that she is there from 3 am ... does costumes really need to get this kind of attitude?"
Cons: "Chairs did not lean back."
Pros: "Ease of travel"
Cons: "Extras that I didn't know how to navigate as a first time Spirit passenger"
Cons: "The flight departed almost 3h delayed. The last hour with everyone already on board and waiting for the company to authorize the plane to depart after 11pm which implied a fee to the airline. They could have planned and get the authorization ready sooner. Seats were not too comfortable: no recline on a red eye flight. no pocket to hold stuff"
Cons: "Airplane seats are never comfortable."
Pros: "It is comportable."
Cons: "Ticket is cheap.I like that but my baggage's price was too much ecpensive.That's I didn't like"
Cons: "I'm only 5'6" and my knees were jammed into the seat in front of me... wildly uncomfortable."
Cons: "The tray tables are too small"
Pros: "My flight into florida not bad except I thought the plane was going to shake apart for the first 1/3 of the ride"
Cons: "Some how they did something wrong when they put my information in the computer for my return flight departing from Ft. Lauderdale. I was not able to check in and print my boarding pass ahead of time. I called the customer service line twice to confirm that my reservation was intact even though I could not print the pass. At the airport there was no "bag drop" so everyone from all Spirit flights had to wait in a line that was 2 blocks long (no lie.) It took 45 mins. to get to the counter. Once there no one could seem to figure out what was wrong and it didn't seem to be a priority for them as they were putting out quite a few other fires. I stood at the counter for another 45 mins. They finally were able to print my boarding pass. Thank god I was TSA approved or I would not have made the flight. That did not seem to bother any of their employees. They won't be seeing me again!"
Pros: "The schedule. Departure and Arrival."
Cons: "Was difficult for the person that was supposed to pick me up to find me at the airport."
Pros: "I liked the price of the ticket. I was looking for an inexpensive ticket without the bells and whistles and Spirit fit those requirements"
Cons: "DELAY, SERVICE"
Pros: "All done well."
Cons: "so many hidden charges and gimmics. I would strongly recommend to ban this ariline."
Pros: "No entertainment available. Only snacks were available."
Cons: "every effort to get more money from the consumer. make sure to read the fine print on all details of expences before you buy the ticket."
Pros: "Flight attendants were not friendly AT ALL. Baggage fees were highway robbery. Charging for a carry on?! Charging an extra $55 for a bag 3 pounds over the 40 pound limit?! Absolutely ridiculous. Never. Again."
Pros: "The pilot was fab"
Pros: "The price"
Cons: "The fact that spirit delayed my flight from San Diego to Vegas for 3 hours, making me miss my connecting flight from Vegas to Detroit by literally 30 mins. They wouldn't hold that plane for 30 mins since it was their fault we were late in the first place. And then the only flight next was 9 hours later"
Cons: "Same as above."
Cons: "I must pay for my baggage. It's crazy couse I paid 100$ for my ticket and 50 more. Food???? What are you asking about?! There aren't free water! It was bad expirience. To go back I rent a car Mustang 5.0 it was more better, exiting!"
Pros: "Ease of boarding. Departure and arrival on time. Friendly attendants."
Cons: "Really small under the seat space and uncomfortable seats."
Pros: "low fare"
Cons: "check in process was confusing- one airport you had to pre-print, the other you didn't, no cell phone tickets allowed. There are higher fees for carry-ons than checked bags. Didn't like the attitude/marketing at all. I've flown other no-frills carriers but these guys just rubbed me the wrong way!"
Pros: "All went well. We took off on time and landed 9 minutes early. Our bags came out shortly after we got to baggage claim. The bags were not damaged in any way."
Cons: "Most airlines offer a drink and a small snack. nothing from your airlines and your flights are not that cheap. plus you only allow 40lbs per bag, most airlines are 50lbs and they dont charge more if you pay for the bags at the counted. They dont make you do it prior to getting there. you have too many fees. I even asked for a cup of ice because my throat was dry. they said I had to pay for it. sorry..... that is B.S."
Pros: "Extremely low price and waived baggage fees for active duty military made our first Spirit flight wonderful. Attendants were friendly once on board."
Cons: "Downfalls were limited legroom, the baggage check line at DTW took over an hour and many kiosks were broken and could not print boarding passes."
Cons: "I was charged an extra $50 to check-in my bag at the counter! Quite mean! I wasn't preinformed!"
Cons: "delayed flight. hidden costs."
Pros: "Because of blizzard was cancelled. Took three days and hours to get another flight. Some on phone were not at all knowledgeable"
Pros: "Good Price Round trip if you have no carry on and no luggage."
Cons: "Everything is an addon Leg room is cramped The crew will let you know that nothing is free. Jokes were bad and stewardess was hard to understand even though this was a US only flight they put a foreign speaker."
Pros: "On-board service Flight information"
Cons: "I got an email stating my flight was delayed by 40 min. Security was going slow but made it to the gate within 15 to 20 min of departure time. By the time I got to gate the door had already closed."
Cons: "I didn't know that I had to pay for carry on bag"
Pros: "Crew was great!"
Cons: "I understand Spirit charges a la carte and is open about it, but come on how can you not even allow your passengers one freaking cup of water?!?!? smdh"
