Airline reviews

Pros: "New seats, comfy, legroom, pleasant FAs"
Cons: "Only coke products. Asked for tomato juice - was told it would be $2.50. Nope."

Cons: "Baggage fees higher than expected and seats don’t recline"

Pros: "Nothing throughout the arrival to landing except the actual flight crew was at an even decent level."
Cons: "After having flown to Austin for the death of my mother my return flight to DC was delayed for over 8 hours. There was minimal communication and no real understanding of what was happening by frontier. When asked about any sort of compensation the employees were extremely rude and difficult. After so many hours they’re required to give a 50 dollar voucher but failed to do so. After not sleeping for multiple nights due to my situation I did not arrive into DC till 1am and had to drive multiple hours home in the middle of the night which was a major safety hazard. Frontier did not offer to compensate a hotel or anything for the inconvenice. Extremely disappointed in the horrendous service provided by the airline in this nightmare scenario"

Pros: "I like that southwest flew out of the same terminal Bc after the nightmares I walked over and happily paid full price for Southwest."
Cons: "2 agents for 300 bags in the same time window is not only unexpectable but poor customer service. Several people including 6 people in wheelchairs were deeply effected by this event not to mention. 100 of passagers without a answers. There was no staff at the 3 gates ! Even before the planes were scheduled to take off."

Pros: "The plane was clean. The food and drink selection was fabulous, although we didn’t get any because the flight was short and turbulent but good to know for next time."
Cons: "Wish I could check in online and have boarding pass sent to phone or print out myself."

Cons: "crew was loud and unprofessional. they were talking the entire flight very loud and then talked about bad experiences they had in the past and their party lives.."

Cons: "Added fees for seat and carryon luggage."

Cons: "Rude lazy attendants. No effort to offer even water to me on a two hour flight. All they wanted us to do was clean up trash to make their job easier. Nickel and dimed and this kind of service?????? Also didn't need a repeated 15 minute sales pitch for a credit card!"

Pros: "very warm staff"

Pros: "Staff was nice"
Cons: "They have stripped down the seats of this plane to make more room to squeeze in more rows. The seats are incredibly uncomfortable even for my short 3 hour flight. The try table is less than the size of a half sheet of paper - you simply cannot put your laptop up and work. $35 for a carry on, nickel and dime you for everything including a drink. Last time I will be flying frontier!"

Cons: "The two hour delay on the return flight"

Pros: "Friendly"

Cons: "Delayed three hours and Frontier nickle and dimes you for everything."

Pros: "Nothinf"
Cons: "I missed my flight on a Thursday and won't be able to leave until Monday morning. Very unhelpful at the original gate in Austin and waited for 2 hours in line to change my flight"

Pros: "Even with very rainy weather in Austin, flight left on time. Crew was very nice on both our flights. Plane was clean. Comfortable enough--about what to expect in this day and age."
Cons: "A lot of fees with Frontier flights. Wny not just include in the original fare of the flight?"

Cons: "HIDDEN. FEES. They charge you at least $17 at check-in to select ANY seat, and another $40 for a carry-on. The tray tables were (no joke) 4 inches by 8 inches, and barely fit a soda can, cup of ice, and snack. Seats were also hard as rock."

Cons: "Well atleast coffee supost to be free on the bord"

Pros: "Flight was on time. The flight crew was very nice. The pilots handled the little bit of turbulence we had, wonderfully. Over all, a great experience."

Cons: "The initial price did not include a free seat . Had to pay $16.00 extra for a seat."

Pros: "NOTHING! They cancelled it!"
Cons: "They cancelled my flight the night before, their website gave confusing information (some places said it was on time, some said cancelled), and I was on hold for SEVEN HOURS!!!!! They never actually answered the phone. Guess what? I went to the airport in person, and nobody was at the Frontier counter for 3 hours. When someone finally showed up, THEY TOLD ME TO CALL THE NUMBER I WAS ALREADY ON HOLD WITH! I told him I'd been awake the entire night trying to solve this issue. SCREW IT! In the end, I went with Delta, costing me $441 more dollars on top of what Frontier stole! Delta was fantastic, the guy who booked me was hilarious and helpful, and I'm never messing with this 3rd party nonsense again unless I get a full refund."

Cons: "All frontier cares about is nickle and diming their customers. The flight was not too much less than any of the other airlines, but I should've done reviews before choosing them. They charge you $20 for your seat on top of your fare when you try to check in 24 hours early. They charge more for a carry on than a checked bag. They do not provide anything complimentary during the flight. Drinks are $2. Overall, I spent just as much as I would've with Southwest of American, but I felt ripped off and unappreciated. If you want a loyal customer base, Fronteir, I suggest you change your flight policies. This is 2016 and customer service is everything."

Pros: "I was fortunate enough to sit next to two passengers who calmed me down during the plane ride."
Cons: "The staff were aloof and slightly unprofessional. They did not seem to be very confident about the flight, which made me worried and concerned about my experience. They rushed through standard procedures and were not very comforting to passengers. I have never flown by myself before, so my anxiety levels were high and I was extremely nervous the whole time. I wish that they would have been a little more easy-going with nervous passengers, such as myself, because I left the flight shaking."

Pros: "got me there on time"
Cons: "cramped flight"

Pros: "New plane. Good deals on food, though you had to pay."
Cons: "4 hours late on departure, with various reasons given depending on the staff. Flight attendants were good at their job, but could not be both polite and stern (as in, please sit down while the plane is still climbing, or even a "Pay attention, please!" said during the emergency evacuation procedure discussion.)"

Cons: "Charged me for CARRY-ON luggage at gate. First off , this is absurd. It reminded me why I fly with proper airlines. Second, this should have been made clear at time of booking so I realized how much the flight would ACTUALLY cost and book with a more comfortable and professional airline. The seats are awful and don't recline."

Pros: "I liked the amount of space I had in my seat that I voluntarily paid to have."
Cons: "The seat itself was not very comfortable. Also, a member of the crew was either not masking her disdain for her fellow crew members very well, or has a wicked case of resting-bitch-face, it was kind of off putting."

Pros: "Price was very low"

Cons: "Plane had a bad part and instead of rerouting another plane or bringing part by special courier they waited for 12 hours for a part. If the CEO or the head of maintenance had been on that flight they would have made accommodations in an hour, not 15. No attempt to get us on the five other flights heading to Atlanta that morning. To add insult to injury Frontier offered a $100 credit for another flight within only 90 days. With bags being $35 each way and picking a seat another $15, that means I get my baggage free only. NEVERMORE."

Pros: "The plane was clean, the staff on flught was professional but I already knew I would have to pay for a carry on so opted not to take one. Stepped on board with a bag to go under a seat which was the only saving grace for a flight with this airline. A reasonable price if you aren't taking much."
Cons: "After the flight I looked at my credit card statement and noticed a LARGE, unexplained charge. (When I say large I mean 4x the price of the original ticket). Turned out that when I checked in they decided I needed my full middle name because the initial wasn't enough, even though that's all they originally asked for. Then they automatically charged me for the change without notifying me! Reported it to my credit card company as fraud until I found out what happened. They ended up refunding the charge, admitting they shouldn't have charged it in the first place, but what a hassle! Not an airline for passengers who care about their money."

Cons: "Didn't make flight because online boarding pass would not scan, and there was no crew at ticketing counter to assist. I was told by TSA, and not the airline, that the same crew at the ticketing corner moved to the gate to board people 45 minutes before flight. Because I was there 40 minutes before flight, I got zero customer service. This was my first and last time flying Frontier! I wish zero stars was an option."

Cons: "The flight crew prior to getying on the plane were rude and outlandish. They have no tact and were not respectful to travelers. You have to payfor what others consider complimentary services. In addition, the flight was delayed with no explanation. I will not be flying frontier again."

Pros: "Good crew and cheap flights."
Cons: "Both destination and returning flights were delayed. I knew about the carry on and checked baggage fees, but it was still a bit of a hassle. Make sure you pay during booking to get the best prices. I did NOT know all drinks and snacks were an extra charge. If you know all this ahead of time and don't have a time schedule, it is a great, inexpensive company"

Pros: "Can't believe I was charged $45 for a carry on bag each way. Soda and coffee starts at $1.99. Was not informed byKayak and priceline that these fees would be in place. The only good thing is this is a nonstop flight Austin to Las Vegas that on united and American has layovers."
Cons: "I will fly Southwest next time because the fees added up to almost $100.00"

Pros: "The price."
Cons: "You shouldn't charge for a carry on."

Pros: "Nothing!"
Cons: "Frontier offers a deal upfront on your ticket price, but does not tell you that the only baggage you are allowed to carry on free is one personal belonging, like a purse. At the counter, they then charge $50 for a small carry-on suitcase( ONE WAY!), or $40 one way if you let them check it on, adding an extra $100 to the price of your ticket, making other major airlines ticket prices more desirable! Then, on board, you find very narrow seats that don't even recline at all, and they offer you nothing on the flight - NOTHING AT ALL, unless you pay for it!!! Then to top off their deceptive treatment of their passengers, their on-line web site encourages you to choose your own seat on the plane, never telling you that you'll be charged each way for that personal choice! If you are able to figure out this trick and continue on to where you allow them to randomly assign you to a seat ( usually such seats are the worst ones on the plane: the dreaded middle seat) you will not be charged! I hate underhanded, sneaky deception and poor service like that and I will NEVER fly Frontier Airlines again!!! There's no way I will encourage greedy dishonest behavior like that and I'll tell all my friends and family members about my experience!!! I hope they rot in hell!"

Pros: "Nothing"
Cons: "Everything..... To begin with I didn't even get to go on the flight I was scheduled for because I got there and when I went to print my tickets.... It was impossible to because it advised me to see the counter person... Well there was no one at the counter so I proceeded to the office... No one was at the office! I ended up missing my flight and losing my money... It seemed like some sort of scam ... Basically a loop you could not get out of and no one es there to help.. Worst experience!"

Cons: "I was charged for everything and your flight was not much cheaper! Luggage carry on, not even a complimentary soft drink! The landing shook my teeth! Honestly not impressed."

Pros: "N/A"
Cons: "The entire experience was horrible. The flight was delayed 6hours in which initially it was due to fog, then no plane available as all.other airlines departed, and there was no representative available during the entire process for Q & A. I had to take another in order to arrive in ATL for a business meeting which I missed."

Pros: "That I finally got home after a long wait in the airport not knowing what was causing the delay."
Cons: "After you add in all of the extras like paying for your seat and carry on baggage, the price isn't as attractive as represented. It was a topic of discussion on the flight when we finally got off the ground. There were 5 gate attendants working the flight that had no earthly idea what was going on and when they did find find out they wouldn't share the information. Overall not a good experience. I can't see a situation where I would fly Fronteer again."

Pros: "Getting off the plane. It was a moment to celebrate- my last Frontier flight ever."
Cons: "The charge for carrying ON a bag. Being told plane was at gate, but couldn't leave at 7a as sched because pilots needed rest. Then being told at 10a that plane was in Houston. Then ultimately leaving at around 11a."

Pros: "Being notified early"
Cons: "Not flying Not receiving a refund our voucher for the (2) 1-way tickets you cancelled & not being refunded for seats we paid to select on a flight that did not exist. Not having another Frontier option until Monday Being asked repeatedly on a call if I'd like to cancel my flight. You cancelled my flight. Give me half my money back."

Pros: "It was on time."
Cons: "Small and uncomfortable seats with no leg room and no reclining, tiny tray tables, fees like no airline I've used, including a charge for carry on luggage, and a website that is not user friendly. Back to Southwest for us."

Pros: "Cheap price for ticket"
Cons: "Pay for a carry-on?! Pay if you want a soda?!"

Pros: "Our seats had enough room"
Cons: "This was without a doubt the worst flight we have ever taken and we will NEVER fly Frontier again. They were the rudest, most unhelpful people we have ever encountered from start to finish."

Pros: "Cost Supervisor Maggie"
Cons: "I arrived for my 6:10 flight at 5:00 traveling for a one day engagement with zero pieces of luggage and one well traveled companion again no luggage. The counter said it would close at 5:25. Odd that a flight was scheduled to take off while the counter was closed but I had no fears I was well within the open hours. I waited for an associate until 5:30 then tried the automated kiosk. It said see an attendant. Back to the empty counter. Called the suggested 800 on the same sign and am accused of lying about my arrival time to the counter and informed I can get the next flight in 13 hours for twice the cost of the round price tickets. Supervisor Maggie got me on the flight at my reserved rate and adjusted my return flight but I was still out the hotel both in Denver and having to pay another night in Austin."

Pros: "Nothing really"
Cons: "Terrible service with lots of delays and was not taken care properly at all. Spent 28 hours in total to reach destination."

Pros: "The crew was very nice."
Cons: "They tricked me into paying a seating fee when I was checking in online by having to select the seat. They also charge a $40 per carry on. The boarding was done horrible, they called zones with only a minute in between so there was people from all areas boarding at the same time. The seats were the most horrible, didnt recline, and were hard plastic with no cushioning. No peanuts or drinks offered."

Pros: "Frontier was fast at boarding and had us to our destanation each leg ahead of schedule."
Cons: "While frontier can rationalize that charging for both checked & carry on helps with efficiency I personally fond it offensive. They also are atrocious in their seating charges. I simply wont fly an airline that feels like a bait and switch used car sales tecniques when I fly. I am willing to.pay more to have simple luxuries like a seat that leans back. Very unorganized system of boarding...."

Cons: "I had a boarding pass on my phone, but when I got to security it wouldn't scan and they sent me back to get a hard copy. Almost missed my flight because of this. I was also unaware that Frontier charges $30 per carry-on per flight. I've never seen that with any other airline."

Pros: "Nothing! I do it because I need the flight in that moment."
Cons: "Everything!"

Pros: "Ladies on crew where very motherly and had a lot of attitude to give everyone. The guy on crew was nice and professional."
Cons: "Calling last boarding 30 mins before departure was not cool. After leaving TSA we had to run at full speed to our plane due to the announcement of last call"

Cons: "Muy bueno el crew"

Pros: "Service, flight"
Cons: "Paid a lot for luggage at the airport in florida vs when i left Puerto Rico and i did not buy anything"

Pros: "Nada."
Cons: "Super incómodo"

Cons: "Horrible females flight attendants"

Pros: "Gate crew of Spirit in MCO Orlando bill me $65 to boarding flight to San Juan with my carry on bag. Nobody’s in San Juan or a Spirit Web site inform me of thie random charge. It’s a Scam!!!!!"
Cons: "I will NEVER flight again with this company and i demand a investigation of this event with Spirit Airlines!!!!!!!"

Cons: "The seats are uncomfortable"

Cons: "seat, confort, dint recline, not tv or movies, no snacks"

Cons: "Good"

Pros: "Excellent crew"

Pros: "Viaje puntual y tranquilo para lo que pague por viajar esta bien con el presio"
Cons: "No me gusto el cobro de la maleta pague 100 dolares adicionales"

Pros: "Military friendliness Crew humor"
Cons: "There doesn’t seem to be an incentive to going through the self check in. I still had to make the long line. The boarding announcements weren’t loud enough which caused people to clog up the line so that they could hear what was being said in hopes of hearing which group was being called to board the plane. I never got offered refreshments on the plane or anything for that matter. I was never approached by any crewmember on the plane whatsoever. No shoulder room when sitting in the middle seat."

Cons: "Very fast"

Pros: "On time"
Cons: "Seat not comfortable"

Pros: "Timely concienced"
Cons: "Awful seating Expensive food and old No complimentary beverages nor snacks 40 pounds for checkin bags ridicule Hidden costs First time traveling and prices shown on internet raised considerably after all extra charges"

Pros: "Fast flight"

Cons: "The landing was a little brut."

Cons: "Getting dinging for bags at the gate, $50 a bag each way?!? Wasn't explicit ok Kayaks website and very financially cumbersome. Not cool."

Cons: "Double booking of seats"

Cons: "Crew food boarding check in employ not profesional"

Cons: "That day was mayhem do to a flight cancelled to Columbia and it took over 2 hrs just to leave the luggage and when I finally got on board I had to have my carry on bag on my lap because there was no space left on top"

Pros: "Nothing, In this life you can never say "never". But God willing, I'll try my best never to fly with this airline again!!!"

Pros: "Nothing"
Cons: "Everything no food,no music,no movies,no enough room etc"

Cons: "Many hidden costs, seats unreasonably small, no drinks or snacks at all unless you buy them, disorganized. Airline appears reasonably priced, but they charge high prices for any amenity usually included in the price. They didnt have curbside at airport, adding to the long lines inside. Elderly passenger had to walk with heavy bags before getting wheelchair. Not acceptable. Website almost imposible to navigate-kept kicking me out and phone service is inefficient . Clearly, everything is set up to make traveler spend the most for any necessary convenience once they arrive at airport. Will not travel with Spirit agIn."

Cons: "I tried to check in online and the first thing I had to do was pay for my carry-on. As soon as I did I had a response that I needed further assistance from a representative and that I had to contact them. When I did, the woman told me that everything was fine. I re-check and told her the message was still showing up. She told me to try on my computer instead because the message didn't appear for her. Oh and before I told someone my problem I was transferred to the operator a couple of times. Finally I pulled out my computer an as soon as I saw the message called back extremely upset and told her that she needed to check with my confirmation number and to please not transfer me to the operator. She confirmed the problem was an error in the billing address. Worst experience for such a small problem. Crew wasn't too happy on the flight, chairs don't recline, no entertainment or drinks. You get what you pay for."

Pros: "flights were on time."
Cons: "they offer me a big space seat for a mistake they make, then change it to a regular seat."

Cons: "Baggege fees (even for carry-ons)....kayak should make note of that prior to having customers book... Not in small letters but large so we can read it.. wld have not purchased tickers if I knew this up front, no snacks or entertainment on a 3 hour flight, no leg rooms, very uncomfortable airline... People packed in like sardines"

Pros: "The pilot did a great job, outstanding, the crew was helpful. I will recommend anyone who is planning to flight somewhere to consider flying with Spirit.............."
Cons: "n/a............"

Pros: "Yes very much"

Pros: "We flew from MCO and a week later we flew from Standford-Orlando (30 miles from Orlando), and the difference was huge. MCO lines are always bad (30 mins to an hour), in Standford we had no waiting time it all. MCO is a beautiful airport, you feel the Disney Magic al the time"

Cons: "Ya que no hay mas que tu asiento, que este limpio. Fue decepcionante al meter la mano en el compartimento del frente del asiento estuviera lleno de basura al igaul que sucio. El abordaje en Orlando fue rudo ya que el personal transmitía su descontento."

Pros: "The flight was on time."
Cons: "The crew was not friendly. The seats were not comfortable.."

Pros: "Smooth flight which h was the most important flight. Thanks for keeping us safe."
Cons: "My seat was taken by someone else It would be nice if beverages were free for such a long flight"

Cons: "The seatare to small for a 6 feet guy and they charge me for a carry on$65 i will not recomend itnot even forprice"

Cons: "I do not like that entails when we bought the tickets that we had to pay for everything"

Cons: "Arrived at 11 am to check in, went through security gate. We went Through terminal, I was traveling with a group that met up and we had 3 small children 1 yr old, 2yr old and 5 yr old. We stopped at 12pm at the food court and bought to go foods. Arrived at the gate at 12:16pm which was suggested. Lady at the counter at gate showed no interest in getting us in our flight. She said we were supposed to be there at least by 12: 20 , when she turned around and looked at the time she realized it was only 12:17 pm and then changed her story and said we had to be there at least by 12:10p. We explained the website said also 12:16pm. She said there's nothing she could do and argued with my sister about how it was us not being "responsible". There was a flight attendant next to her while all this was happening, (We were turned away by the lady with boarding passes for next day. SHE DID NOT ATTEMPT AT ALL TO GET US BOARDED SHE KEPT TURNING US AWAY). THE FLIGHT ATTENDANT, came running towards us at the food court where he happened to find us and told us to hurry that he was able to communicate with the pilot and he gave the ok to board. We threw our freshly purchased food in the trash and ran with out kids in our hands to the gate. As we got back to the gate area the lady called him and said no that it was too late. The flight attendant was upset and hinted to us that the lady was just being difficult. We missed the wedding we were attending and we threw away food we had just purchased. The FLIGHT DEPARTED AFTER 12:30 AND SINCE 12:16 BESIDES THE FLIGHT ATTENDANT, NO ONE TRIED NOT EVEN ONCE TO GET US BOARDED. needless to say the kids car seats were in the plane along with the checked in luggage and the car locked in a security garage til monday. We were stuck and strabded and spent an additional 85$ just to stay in a hotel near the airport. We woke up this morning in our same clothes and are here in the airport today hoping for better customer service. The most HORRIBLE SERVICE EVER."

Pros: "What I supposedly saved in ticket prices was made up in baggage fees. I had to pay $ 55 for a carry on bag??? $2 for a cup of coffee on the plans. I will Seriosly THINK before booking a Spirit flight in the future!!!"

Pros: "The crew was expecially attentive, changing my seat from row 28 to row 4 (I am disabled)"
Cons: "No food or snacks"

Pros: "Please stop sending me this.. You will not get a good review from me .. Your airline is horrible from start to end!!!!!!!!!_"
Cons: "Everything"
