Pros: "I was comfortable."
Cons: "Nothing, the flight was fine."
Pros: "The crew called out beautiful sights as we passed over them. The flight attendants were sweet"
Cons: "Would have been nice to have some entertainment"
Pros: "Price was right and my golf clubs arrived without incident."
Cons: "Flight was delayed over 1 hour with little explanation."
Pros: "Nothing"
Cons: "Everything"
Pros: "Flight duration"
Cons: "The delayed plane that they wouldn't tell me why it was delayed"
Pros: "Great price!"
Cons: "The seating is even tighter than normal coach, but my flight was only 2 hours so it was no big deal. I don't think I would take a longer flight with seating that tight."
Cons: "Spend the extra money to get treated like a human. The savings aren't even that great after they nickel and dime you for literally everything. You save pennies to have the worst flying experience of your life."
Pros: "Nothing. Literally nothing at all."
Cons: "This situation is a clear statement about the unfortunate state of affairs regarding "customer service". If anyone uses the bromide "the customer is all important", cite this example as proof positive of the lie that is that tired statement. This circumstance, was, essentially no one's fault and yet the employee reaction on behalf of Frontier airlines speaks volumes to the general attitude that the ORGANIZATION takes toward its paying customers. Due to delays on the first leg of the trip from DC to Denver, the connecting flight was missed. This is understandable on its own, as I have no expectation that a second flight would be held for me. However, the fact that Frontier, as an organization, feels ABSOLUTELY NO OBLIGATION WHATSOEVER to assisting their customers in arriving to their ultimate destination in a timely manner means they will never, EVER, get my money again. To make matters worse, the two options they DID offer, were unacceptable: 1) Offered a flight to an airport an hour away from my destination & 2) Offered a flight to my actual destination...two days later (in the airport on Tuesday; they offered to get me on a flight to my destination Thursday) AND this offer with absolutely no assistance regarding sleeping arrangements for TWO NIGHTS. In short, trip was complicated for which I do not blame Frontier. However, their complete lack of customer service to a paying customer ultimately has cost them future customers. My family travels frequently and I will certainly advise any and all persons I know NOT TO EVER TRAVEL ON FRONTIER AIRLINES! I will, however, recommend the FAR MORE CUSTOMER FRIENDLY DELTA airlines)"
Pros: "Nothing"
Cons: "The staff was rude, line to check in luggage was huge because they were understaffed. If you don't get your bags checked in 45 minutes before your flight, you don't get on your flight. I had already been in line for 20 minutes and when I got the the desk at 40 minutes until my fllight, she said "too bad." Great Mother's Day for me sitting in the airport for 7 hours until the next flight out. Girl was horrible and totally rude. Never again."
Pros: "Bigger plan. Not over booked"
Cons: "Price of food"
Pros: "Fast boarding. Crew is super friendly. Thats about it."
Cons: "Seats are increadebly uncomfortable. $3 for a soda, not even a bag of peanuts is offered here. No entertainmet, no movies, no wifi. Not even a magazine No tray where to put your food or ipad. no pillow, no blankets. $40 for a carry-on bag $20 to pick your own seat at checkin."
Pros: "Flight time"
Cons: "My flight was delayed twice, so I arrived an hour before my departure. I could not check in online because of the flight delay. When I went online to check in, I kept receiving "error" messages. Once I arrived at the airport there was a long line of people waiting to check in. NO ONE was using the check in kiosks for the same reason they could not check in online. As a customer, I expect to have the availablility of resources when checking in online. This is how I always check in. Your technical issues is irresponsible on Frontier's end. When I was finally greeted by the agent, she said that there was 41 minutes until departure and that I could not check in my bags. I asked if I could put my bag onto another flight. She said that after 9/11, they do not allow passengers to board flights without their bags. I asked to speak to her manager. She tried calling the manager who was not picking up her phone. After she got ahold of the manager, it took her ten minutes to come down. I asked Frontier's manager, Brehona why it took her ten minutes. She was immediately offended and rude. she did not even try to assist me. She told me I needed to rebook and could not waive a $99 booking fee. This was a lie. I called Frontier's customer service to at least have the $99 fee waived because it was not my fault I did not make the flight. I was on time. In comparison, I have been in a similiar situation (with a different and much better airline) where the manager was where she was supposed to be, which was behind the counter actually doing her job managing. The other airlines manager was able to go outside and contact other people to get my bags onto the flight. With Frontier's manager, she made zero effort to assist me. On top of that, she notated on my account that she was not removing the $99 fee. This fee IS waivable, especially under the circumstances that I was in: my flight was delayed twice, I missed the cut off time by two minutes and that time increased due to the manager's behavior and untimelines responses to her employees. because the Frontier's manager Brehona made that notation, I could not have the fee waived because they do not override decisions of other managers. I had to book a new flight and pay the $99 fee. I confronted Brehona and told her that the fee is refundable and customer service was going to refund me if it were not for Brehona's notation. She lied that she did not make that notation. I told her that I knew she did. She admitted to it then went crazy and said I cannot get on my second flight that I just booked!!! She called security to try to kick me out. Of course I wasn't kicked out of the airport because I didn't violate any laws. Brehona provided me with bad service, created a hostile environment for me and was going on a power trip harassing me and refusing me flights. I called Frontier's customer service and they told me that my flight was non-refundable. Worst experience of my life. I will never fly with Frontier again!"
Pros: "It's cheap which is nice but beware of hidden fees"
Cons: "It's more expensive to CARRY on your luggage rather then check it!!!!! I feel like it's a sneaky way to charge you as people mostly try to carry on. They do that to AVOID extra charges. May sound petty but it really irked me. On another note, when ordering a cocktail you pay on a IPAD which asks you the percentage of gratuity you would like to leave. Grossly inappropriate as flight crew cannot except tips under FAA law."
Pros: "Unable to check in on line (as is recommended). Customer service would not allow callin check in. Check in machine at airport would not allow checkin. Counter person unable to process checkin, initially. At first denied I had a seat. Later found my seat. Seats were beyond comfortable. No room, if instructed to lower head for impact (anticipate law suite)."
Cons: "We have several flight delays with no connecting flights to our destination. We were rerouted to another city, rented a rental vehicle, and then continued to our final destination."
Pros: "Flight Crew was the standard affair."
Cons: "the 'customer service' for baggage handling or lack there of. Terrible if it were free, but as a paying customer atrocious. Also didn't appreciate the tiny trays that can barely hold an iPhone 6."
Pros: "Smooth boarding and left on time. Good temperature on board."
Cons: "Seats do not recline, are not very padded, and no headrest. Very tight seat spacing (no legroom). I am not a very large person and my knees were hitting the seat in front of me. Only free beverage is water. No free snack. No inflight magazine. I usually fly Southwest but they didn't have a flight when I needed to go. Frontier was on par with SWA in terms of price, but far inferior in terms of onboard experience. I will not fly them again, it was quite an uncomfortable flight."
Cons: "1. Flight go pushed back a full day after spending 5 hrs waiting at the airport for any concrete news. 2. Ended up being told Frontier couldn't get me home untill 4 days later. 3. Paying Southwest about $600 for a same day flight back home. 4. Missed 2 full shift days of work."
Pros: "The flights seemed cheap ar first however they have hidden fees for picking your seat and basic carry on luggage at the time of check in. Pretty disappointing when you to plan a budget and get charged an extra 120 dollars"
Cons: "The flights seemed cheap ar first however they have hidden fees for picking your seat and basic carry on luggage at the time of check in. Pretty disappointing when you to plan a budget and get charged an extra 120 dollars"
Pros: "The flight was cheap, the crew was nice, the airplane was clean and they got me to my destination on time with no delays. What more could you ask for!?"
Cons: "If I had to complain about something I would say the seats were a bit uncomfortable and the tray tables were very small, but it is nothing short of what I would expect of a 3hr flight for under $200. ^_^"
Cons: "On both flights, the for sale snack options were poorly stocked... no menu cards in my row, when I asked for one (because they told us to chose before they got to us).... they brought me one that was torn and falling apart Most folks around me were surprised they couldn't get water or coffee without paying extra."
Pros: "It arrived safely."
Cons: "First they cancelled my afternoon flight and moved it to the am causing me to miss a day of work. The employees were sullen, the flight was crowded, and they charged 50% of the original ticket price for a bag ( original $186, bag $90). This was a surprise. Their customer support is in the Phillippines. Their cost cutting is rediculous. I will pay more and fly a different airlines next time."
Pros: "There is no longer anything to like about Frontier"
Cons: "Charged bag fees at kiosk. Then told they couldn't take bags because of their cutoff time. Then told I could call customer service to get a refund. Then told by customer service they could not refund fees even though they would not provide the service. Oh...and they wanted $99 to book on the next flight. Even though the flight they wanted to book me on left the next night!"
Pros: "Nothing"
Cons: "Two-way flight was booked and paid for two months in advance. The day of first flight Frontier sent email notification that return flight was, "Adjusted". Frontier made an adjustment to all its passangers without their knowledge or approval. The change was a nine (9) hour layover arriving at midnight! No full-paying customer would ever consent or pay to sit at an airport for 9 hours!! This was the only available flight Frontier had available on this travel day. Flight was canceled and reimbursed, however we're still out lots of $ in order to last minute book a one-way flight with another airline. Frontier = Worst Airline - avoid the stress and headache.. Please do NOT fly with Fronteir Airlines."
Pros: "Happy energetic voice of pilot"
Cons: "Plane left an hour late."
Pros: "On time both ways"
Cons: "Narrow pitch between seats, Seats did not recline. No snacks Extra cost for carry ons"
Pros: "The flight itself was OK considering the price."
Cons: "My luggage (and those of a few other passengers) did not arrive with me and I spent one hour for bagage claim. There was no clear reason for that: it was a direct flight and the luggage was registered two hour before the departure. However the luggage was finally delivered to my hotel the next morning."
Pros: "Great service from Frontier Airlines. I had to change flights to an earlier date and time and it was an extremely smooth and simple process."
Cons: "No reclining seat...maybe mine was broken."
Cons: "Price shown in search engine is not accurate. When you book the flight you are forced to choose a seat and every single seat on the airplane has an upcharge ($5 minimum but a lot more for the front of the plane). They also charge you to take a carry on ($60 at the gate). It was actually more money to carry a bag on that it was to check a bag. They artificially deflate their prices in search engines so they populate 1st and then up charge you when you get to the airport. The planes are dirty, seats are uncomfortable as the arms are still in your way when they fold up. I've now flown 3 times on frontier and the planes had terrible turbulence on the takeoff and landing. I have nothing good to say about my experience. Take another airline and at least you'll be paying the correct price up front, not weaseled into paying more when you check in for your flight."
Pros: "^"
Cons: "^"
Cons: "Delayed"
Cons: "2 crying babies( that part was just bad luck), the plane was dirty and not well taken care of, the flight attendants were rude, had to pay for beverages. Terrible experience. Will not ever fly this airline ever again!"
Pros: "The Crew"
Cons: "Cost to buy seats and carryons is a joke the flight becomes just as expensive as the standard commercial flights on American Southwest etc, I will not fly Frontier again if I can avoid it."
Cons: "Almost missed our connection because we didn't see the email. A text would have been more appropriate as would them announcing it over the loud speaker in the airport like every other flight. No food or entertainment, uncomfortable seats and the smallest trays that could barely hold a cup."
Pros: "Crew was very nice and helpful in a bad situation. The luggage was delayed and not loaded until my the pilot himself helped to load the plane."
Cons: "Then there was another issue with fuel. The flight was delayed 2 hours."
Cons: "my mother in law was supposed to be on a flight Fri morning and was delayed until 2am Saturday in the middle of the night. awful service."
Cons: "I didn't like having to pay extra for my seat on both flights, pay for my carry on that didn't fit in your overhead compartment, and pay for my only carry on, a backpack. I paid for my flight, that should be the price of my seat and the things I need to travel. I pack light and I still had to pay an extra $100 on the day of my flight. VERY dissatisfied."
Pros: "Price is comfortable"
Cons: "Seats are uncomfortable"
Cons: "Lost my bag, enough said"
Cons: "Size of tray table, no entertainment, no wifi, literally just sit uncomfortably and stare straight ahead. Man I used to love frontier but y'all are terrible now."
Pros: "The crew was nice."
Cons: "The flight was over and hour delayed. And frontier has gone out of their way to make the shears more uncomfortable For a tall person. Not much room for my legs, and no head rest when you are taller. I will do what I need in the future to avoid frontier all together."
Pros: "The crew"
Cons: "The "new" seats are uncomfortable, cramped leg room, having to "buy" your seat and no complimentary soda or small pack of nuts (or pretzels). You pay a lot of $ for not even getting any of that. :("
Cons: "Flight started with a two hour delay. Over boarded plane causing additional delays. Lost my luggage for three days and couldn't track it because the company doesn't have scanners. Couldn't find anyone at Frontier in San Diego that wasn't rude and unhelpful. After countless calls to SD baggage, and then Denver and then central baggage, I finally found someone that spent the time tracking my bag. It was delivered three days into my trip."
Pros: "I'm glad I got to San Diego."
Cons: "Watch out for add on fees. My $250 airfare ended up over $310 by the time I paid for just 1 checked bag. A carry-on would have cost more. And the seats are not that comfortable. I would have been pretty upset if I had paid the advanced seating fee ($5-$40)."
Pros: "Price"
Cons: "One person checking bags. Same person running the Alleigiant boarding gate and Frontier. Plane was late taking off at both legs of flight."
Cons: "* Molded plastic seats (never seen the like!) * Charged for every little thing so that it ends up not being as cheap as it seems. $60 to check each bag, charge for carry-on as well, charge for choosing a seat, charge for soda/juice/snack.... * Flight was late boarding and then they tried to rush us in and told us to hurry as if it were our fault. We then sat for ages without being told why. We ended up being 2+ hours late to a destination that was 1 hr 50 min away."
Cons: "We left 20 minutes late because we were "waiting for five people". I only found the reason for the delay after overhearing a flight attendant, not because they made an announcement to keep the passengers informed."
Pros: "How Frontier used to be"
Cons: "- Bag fees ( every other airline allows 1 carry on and 1 personal item at no extra fee) - Terrible customer service... My app said I checked in successfully online the night before my flight which was not the case when I arrived at the airport kiosk in San Diego. I was 1.5 hours early for my boarding time and ended up missing my flight due to no representatives at the counter and a 90 minute phone call with Frontier customer service. I am a frequent traveler and use Frontier for 90% of my flights. I will soon start flying with other airliners and build points with them as I am fed up with the lack of organization and care that Frontier has for its customers. I should be compensated for all the troubles I have been through with Frontier over the past few years!!"
Pros: "See my comments on the flight from San Diego to Denver"
Cons: "See my comments on the flight from San Diego to Denver"
Pros: "Once I found out I have to for everything from carry on to water there was nothing to like about booking on Frontier."
Pros: "Everything!!! Super impressed!"
Cons: "That I had to leave the amazing experience and go on vacation. :("
Pros: "The gate attendant was super helpful and changed my seat to one closer to the front because I needed off the plain quickly for business. Te flight crew were personal and engaging, and made the trip lighter and fun (even). Well done crew!"
Cons: "The great price and then a la carte everything else is frustrating, but if you fly Spirit, you know what you're getting. The baggage fee for a carry on was too high in my opinion."
Pros: "Flights are on time, clean and basic"
Cons: "No carry on bag, so fly light"
Pros: "Easy"
Cons: "Little fees"
Cons: "The checked baggage...$84. REALLY? That will make me rethink my future travel plans...with other airlines."
Cons: "Worst policies of any company I've ever flown with and I will never fly with them again."
Pros: "Price and Spirit employees."
Cons: "Being a sardine, and getting nickle and dined."
Cons: "Not enough leg room, seats need more cushioning."
Pros: "Nothing"
Cons: "Canceled my flight last minute, didn't notify me at all."
Cons: "I paid more money during check in to an upgrade seat. Once on the plane, other passengers sat WHERE EVER they wanted. The staff had problems with accountability because seat numbers and ticket assignments were completely ignored. What good is a seat assignment if staff ignores the flight manifest. In the future I will no longer fly spirit because you do not value my upgrade. I feel you have unfairly taken my upgrade money only to find out that passenger's can ignore the upgrade costs and sit anywhere in the plane."
Cons: "1.Seated next to a very large man that should have bought 2 seats. I was only able to occupy 3/4 of my space. It was a very uncomfortable flight with having part of a strangers body touching and crowding me. There were no other seats available to move to. 2. When I asked for a glass of water, they do not give you, but you have to pay. 3. ALL other airlines allow a purse and a small carry-on. They charge $55.00 dollars. 4. They charge double for check in bag. $50.00, most others charge $25.00 I will not fly with Spirit again and heard other complaints from other passengers. This will be a short-lived airline."
Cons: "I missed my flight and my tickets were unrefundable and my bag went to San Diego. I still have not received my bag"
Pros: "I will never fly with them again."
Cons: "Customer service was aweful. Women at the front would not allow my ticket to be printed however I was already checked into my flight. They are crooks trying to squeeze money out of their travelers. If this isn't taken care I will no longer purchase from kayak either. I have been a long standing customer of yours. It's the only app I use to purchase tickets. I am now missing work and was forced to pay 100$ to get a later flight. Very disappointed."
Pros: "The cost of the trip was very low - with all the frills removed, air travel can be relatively cheap. Plan ahead - you will not be able to use TSA Pre-Check, you will have to pay extra to carry on a bag (so buy your bag online at the airline's website before you go to the airport - this is the cheapest way to do it as they charge you more to purchase the carry-on at the check-in counter and even more if you wait until the boarding gate), and you will have to pay for all beverages including water and provide your own in-flight entertainment. If you plan ahead and know what you're getting into, flying Spirit can be a pleasant experience. The flight staff is friendly and polite."
Cons: "The seats are very close together - don't expect to have any leg room - and they do not recline. Bring a neck pillow if you have any intention of sleeping."
Cons: "I was told I was too late and missed my flight only to find an email from spirit the day after saying my flight was delayed an hour and 15 mins. I could have made it but the lady that "helped" me told me there was nothing I could do. She basically turned me away, along with the 15 or so people who had the same issue ahead of me in line, and advised me to find my own way home on a different airline. I ended up paying $345 to make it back to San Diego and received no help from spirit. Best part: I paid for insurance on my ticket just in case something like this happened. I've never been so dissatisfied with an airline and will NEVER fly spirit again!!"
Pros: "It was actually probably the best flight ive ever been on. Im usually really afraid to fly but the takeoff and landing were so smooth. No anxiety at all. All the crew was so nice and everything was comfortable."
Cons: "There wasn't really anything i didn't like. Every little thing cost money but i knew that going in so it wasn't a surprise."
Pros: "Horrible"
Cons: "Everything"
Pros: "The lady at the desk at the gate was very polite and understanding."
Cons: "Our flight was delayed, and delayed, and delayed while the airline told us it would be boarding "momentarily" and "shortly". The maintenance issue could have been easily solved by doing proper post flight checks, as our flight was supposed to be the first to leave in the morning and the issue with the plane had been there since the night before. They offered us $50 vouchers for use with Spirit Airlines, which won't be terribly useful since we won't be flying with them again. They refused to even try to credit my card with the voucher amount to pay for 400 miles worth of gas and parking to get to and from the airport. The real disappointment with Spirit Airlines is in their ability to perform maintenance properly and their customer service representatives' lack of professionalism."
Cons: "Smaller than usual seat space"
Pros: ",I like that you didn't pay attention that my seatbelt was not attached and I didn't have to argue with him about it"
Cons: "everything else"
Cons: "Being delayed 5 hours and the stewardesses demeanor."
Pros: "Assigned seats"
Cons: "Paying for carry on, customer service was horrible."
Pros: "The planes are new so there's that."
Cons: "The flight was delayed 3 hours due to leaky breaks and they didn't have the air on so we all sweat to death until someone decided to flip the ac switch 2 hours in. The tickets are so cheap cause you have to pay for eeeeeeeeeeeverything! You have to pay for a carry-on, a drink, to have the service desk check you in, etc. I'm surprised they don't have a coin-lock on the bathrooms or individual oxygen masks that they charge you for."
Pros: "Flight was on time and people were friendly"
Cons: "I didn't have any leg room"
Pros: "A lot of people give Spirit a bad rap. READ THE WEBSITE and you won't be disappointed."
Cons: "Boarding, food? that's funny!"
Pros: "On time"
Pros: "The price."
Cons: "They charge 65 bucks (roughly exchanges at the dollar value) for 2nd carry on which is ridiculous. My boyfriend and I had to wear all of our clothes to eliminate that 2nd carry on bag."
Pros: "On time. Prompt service. Easy kiosk check in experience. Price is right without bags."
Cons: "No TSA precheck. Seats are pretty uncomfortable after 2 hours. Have to pay for larger carry-ons."
Cons: "Wasn't allowed to board flight. Lost ticket in taxi and when I tried to reprint at the kiosk, they said that because I was "checking in" less than 45 minutes before my flight that I would be bumped to a flight the next day. Had to buy a flight with a different airline."
Pros: "The crew was friendly, refreshingly casual, and very accommodating."
Cons: "The flight was delayed over an hour. After the agent at the gate told us we could go grab a bite to eat because of the delay we came back and they had boarded the airplane and wouldn't let us on our flight. Never flying Spirit airlines again."
Pros: "nice crew. cheap tickets"
Cons: "On both my flights the departure was delayed atleast an hour without any of us knowing why. It wasnt even mentioned that it was delayed until after the stated departure time. really uncomfortable seats without and reclining or head rest adjusters. i guess you get what you pay for though"
Cons: "$55.00 for a second carry on is too expensive , it should be $25.00."
Cons: "flimsy tight seats, no bargain if you you have a bag (who travels without at least a carry-on?)"
Pros: "Cheap fare and the flight went just fine. On time and no problems."
Cons: "Seats were a bit narrow and cushion wasn't something I'd want to spend more than 3 hrs or so in, but I get the concept of the bare bones service. $40 for a checked bag is too high. I don't mind $25-$30, but $40 is a bit much."
Cons: "first flight had over a hour delay, returning flight had even longer delay due to sharing a terminal"
Pros: "The flight was very smooth, and the flight attendants were awesome."
Cons: "Everything was nearly perfect I just never give five stars"
Pros: "not much"
Cons: "Denver has a blizzard the night before. Let's assume, it's going to remain a cold night after the snow stops. If your flight leaves at 710 am, you might think there would be ice and frozen things on the plane that might need to be addressed before the flight can depart. at 730 they come out and say "the plane's engines are frozen, sorry" Why was no one there earlier prepping the engines? There was NO indication by the crew that any prep happened before. They gave us the impression that they were as "shocked" as we were. I would have assumed that it would have been an issue for all the airlines, but the American flight that was at the gate next to us took off on time, as did the other plane next to us. This is clearly a Spirit airline issue. I somehow made it to denver international airport on time, against all odds. I was going to be able to make my meeting in San Diego on time, but then the ONE thing that's supposed to go off without a hitch (the airplane being ready to go) didn't. All because of clear lack of preparation after a storm. Never again spirit airlines. EVER."
Cons: "Cancelled fligjt 2 options 1, take $44 refund on unused flight portion and figure how to get back to San Diego or 2, rebook flight 3 days later wtf??????"
Pros: "The flight was delayed for a while because of weather, it was a nice flight."
Pros: "Low flight cost Flight was on time"
Cons: "$55 baggage fee Small cramped seating"
Pros: "Great flight"
Cons: "Weight restrictions are to restrict only 40 lbs other airlines 50 lbs"
Cons: "Smallest most uncomfortable seat and row I've ever been on. Chair recliner was broke too."
Pros: "I bought my tickets for $78 a piece. I was able to sit up front in the larger seats both ways with on extra cost."
Cons: "You had to pay for everything even water. Bags cost too much so I only brought a personal item with me. There was no TV. The flight was really loud."
Pros: "The staff were very friendly and the flight was on time."
Cons: "Having to pay for carry ons and food including water and/or coffee. I can get cheap flights from other airlines who offer free carry ons and complimentary drinks/snacks. The seats are terribly uncomfortable with holes in them"
Pros: "Price, on time, friendly"
Pros: "Cheap fast."
Pros: "They were very accommodating to me and my service dog, the crew was also very nice."
Cons: "The unexpected charges, the seating is way to tight. If I did not have a hole row to myself it would have been a very uncomfortable ride for myself and my service dog."
Pros: "the de~icing on then plane wings scared the %*@* out of me. but I'm from Calif, never saw that b4. and thanks for bringing me home safe."
Cons: "I didn't like the fact that I had no warning of the $50 to check bags, or $55 if you take them on the plane. Thank god I had exactly $50 left to my name when I boarded the plane. so in the end it was still $100 one way flight. Next time I'll fly southwest"
