Pros: "Everything else was fine."
Cons: "The flight was delayed 30 mins prior to boarding for 6 hours. They were missing a part that needed to be ordered. What I don't understand is why they couldn't have emailed everyone to notify us so we weren't stuck in the airport for 6 hours."
Pros: "Crew was friendly"
Cons: "Late departure"
Pros: "Everything was fine boarded easy, during layover in Denver g or and some food and took a power nap."
Cons: "Nothing"
Pros: "The flight was cheap"
Cons: "They don't even give you water. Frontier airlines is comparable to Spirit. You have to pay for everything. They don't even give you water or nuts or anything. The seats are harder than the average plane, and they do not recline. Leg room is also horrible. I have flown with them a few times and have overall had a decent experience in comparison to the low price for the flight. It gets you where you need to go with no extras."
Pros: "Fast everything"
Cons: "Small seat space/isle room I am 6'4 and had trouble keeping circulation in my legs. And the last second $45 fee means never again for me!"
Pros: "We appreciated the cheap airline ticket prices."
Cons: "We were outraged by having to pay $45 for each piece of luggage, including carry ons! After these hidden fees, our tickets would have been cheaper for a well established and popular airline."
Pros: "The flight left on time and I arrived at my destination at the correct time."
Cons: "The Frontier rep at the front charged me $45 for a carry on, when I had just flown Frontier and they did not charge me for my carry on. An additional $45 I was not planning on spending."
Pros: "The other passengers were very helpful"
Cons: "Small seats that don't recline. Rude stewardesses. With a connecting flight leaving on time is a factor in my experience. My flight did not leave on time - was an hour delayed."
Cons: "Seats don't recline. No kind of service at all."
Cons: "11 hour delay .....Flight 740 From phx to den departure @6 am had a mechanical. First it was going to be delayed until 10 am them 11 am then 4 pm then 530 pm .it left at 6 pm . It got in at 9 pm by the time we got the car and got to out friend home it would have been close to 11 . We would have been up for 20 hours ( got up at 3 am to get there for a 6 am flight . We were going to a business meeting in demver in the morning in the afternoon a 70 th birthday lunch for my best friend. This trip was planned for months . We live in phx after it was clear we had missed both events we went back home @5 We ended up paying for a supper shuttle and a rent a car in Denver . We paid all that money To go noware the customer service woman there , was uncaring to everyone on board we were just on our own . I am heartbroken we missed the party ."
Pros: "Flight prices"
Cons: "The delay then missing my connecting flight."
Cons: "My flight had a six hour delay and the whole Phoenix Frontier section of the terminal was packed because there were multiple flights delayed. All for mystery "mechanical" issues."
Cons: "Flight was late. Charge for carry on bag. This is the reason I will avoid flying this airline unless as a last resort. This trip was for a funeral."
Pros: "On-time factor"
Cons: "Having to pay for basics"
Pros: "The desk and gate staff was super helpful!"
Cons: "I understand that weather can't be controlled, but I feel as though more could have been done to get me to Philadelphia...even if that meant sending me to another city instead of Denver, for a layover."
Pros: "The trip was excellent, the flight boarded and took off on time, and we arrived early! Great flight"
Cons: "The seats are not angled to fit the figure of a person. The back of the seat leans back and the head of the seat is perfectly straight up. It meets at a point where that does not line up with the persons body height depending on the person. If you just leave it at one angle of give it the potential to lean back just enough, People will be that much more comfortable. I wasn't the only person who mentioned this on my flight, in fact I spoke with 3 people and overheard others complaints as well. One angle or at least a centimeter of space to lean back...I don't think it will mess with people behind them since there's no tv or entertainment and I think it will continue to bring more people into frontier."
Cons: "Frontier personnel at the ticketing refused to print out my airline ticket and allow me to try and catch my flight because we had not checked in 35 minutes prior to flight departure. I missed the flight and had to eat the price of the ticket and find another airline to get to my destination. There was plenty of time to have made it through TSA and boarded the plane but because of some ridiculously stringent policy they would not allow me to try."
Pros: "Arrived on time"
Cons: "Crew yelled at child for trying to carry on skateboard, cost of carrying on bags, no free food...or even water, charge to guarantee you get to sit w family. Up front cost does not represent what you'll "pay"."
Cons: "As the other airlines were flying out of Denver despite the falling snow, Frontier cancelled almost every flight anywhere. Including ours. To their credit, they refunded our money, but its hard to need to go somewhere and the airline you've chosen is sitting on the ground. Very bad form."
Pros: "I have flown with frontier multiple times, and everytime there is an issue. From lengthy delays, rude employees or overly priced checked luggage. And not only that their new seats are so uncomfortable and don't recline back. The Some what lower prices aren't worth it any more. I will not be flying with frontier anymore."
Pros: "nothing"
Cons: "ticketing staff didnt seem like she wanted to work, seats were uncomfortable, time management was poor"
Pros: "No real reason as to why they cancelled it but they had two other flights go out that night...Not only that but the following flight the following morning went out. I understand things get busy but accommodate accordingly, maybe provide a hotel and not a voucher for one more flight. I had important plans and they really had no answer to remedy the situation."
Pros: "My 15 year old hasn't even boated her flight as it is delayed until 2:33 am. She was to leave PHX at 7 something this evening. Disappointed with Frontier-will not use this airline again nor recommend to family, friends nor clients."
Cons: "3 1/2 hour delay. Disconnected staff"
Pros: "Crew was nice. Plenty of overhead space (probably because people don't want to pay to bring on a carry on anymore... so the negative lead to a bit of a positive)"
Cons: "Seats are SO UNCOMFORTABLE!!!! I don't know what they have against the human body, but the new seats have no cushion, no lumbar support, no neck support and there's not enough leg room. I know they want to save money and offer cheaper ticket prices, but I don't know why a seat has to be rock hard in order to make that happen."
Pros: "My initial flight from Denver to Phoenix was a hour late, but lets talk about the way home.... Flight got in OK and then we waited 45 minutes for a gate to open. Could you park us at another gate? That would be too simple. When we parked we waited another 20 minutes while they put a jet way in place. Now answer this... the other plane just left that spot, so what happened to the jet way from that plane? Do they completely take it away or just fold it up? Fold it up I bet , so it was in place just had to be opened up. I guess they couldn't find anyone to do that. I know this sounds petty, but I have never taken a Frontier flight that went smoothly. Thank God I haven't had to take many. And it's not as cheap as it looks by the time they get you for bags and a charge for your seat. I ALREADY PAID FOR MY SEAT, WHAT'S THAT ALL ABOUT. Bye Bye Frontier, I'll pay more for the service issues."
Pros: "Price"
Cons: "The same 2 screaming babies entire flights. Attendants allowed with no assistance."
Cons: "The crew was a mess. They gave very vague answers to why we sat on the run way for an hour and half in Denver. We all almost missed our connecting flights. They actually held every Frontier flight from Denver so all of those passengers were pissed. I will NEVER fly them again. When they say they are CHEAP they mean CHEAP ALL THE WAY AROUND. Even the pilot suggested we write Frontier and complain. Sounds like they have major issues."
Pros: "I like the fact we landed safe."
Cons: "I didn't like the that none of the worked knew how to communicate with customers. I think the workers should be taught the concept of customer comes first."
Cons: "No agents were present at the gate for about 40minutes-1 hour, during the period when the flight was supposed to depart. The Frontier monitors were never updated."
Pros: "Delayed 2 plus hours no plane no explanation no offer nothing"
Cons: "Waiting all night"
Pros: "Quick off and on"
Cons: "No one checks people on how their kids should behave. Two hours I had my seat kicked and clawed. No matter the age, a child needs his or her own seat. The flight attendants need to be more apt to the problems caused and less to how cute a child may or may not be."
Pros: "Absolutely nothing"
Cons: "Wanted an AM flight...got to the airport to check in 6:30 am to find out I had booked a 8:05 PM flight....so we had to book a fly another airline."
Cons: "They charge per EVERY bag, even if its a small carry on. Cheap once you buy the ti kets but adding the baggage prices, might as well travel on a better airline. Their customer service via online and telephone is awful"
Pros: "Crew was very nice and helpful."
Cons: "Beverages had to be paid for, even water, coffee or soda. Snacks for purchase were junk. When I arrived there was no wheelchair available even ordered. Was delayed over 30 minutes because they didn't have staff nor could they locate a wheelchair. They need to take a lesson fro Sky Harbor in Phoenix. Very well organized system there by ONE company. Efficient and delightful personnel."
Pros: "There wasn't any entertainment so can't rate it. Flight was very smooth and on time."
Cons: "Well I would have thought my seat would have been included in the ticket price and I think it is ludicrous to have to pay for coffee water or soda. I just went without. Never flown on a flight where that wasn't free. Seats are small and I am not a large person."
Pros: "Very horrible service bumpy ride"
Pros: "Plan was on schedule, the staff was friendly and it was a smooth ride."
Cons: "I didn't like the fact that all food and beverages were an additional cost and the bag fee of $30 in addition to the ticket price."
Cons: "PAYING EXTRA FOR SEAT SELECTION TO DENVER PAYING EXTRA FOR SEAT SELECTION TO SALT LAKE CITY PAYING EXTRA FOR 1ST CHECKED BAG POSSIBILITY OF HAVING TO PAY FOR CARRY ON BACK PACK"
Pros: "Easy check-in, on-time flights and easy boarding."
Cons: "Frontier claims to have low prices, but once you pay for your seat, carry-on bags and checked luggage, you're ultimately spending more than any other flight. It makes sense to me, that if you purchase a plane ticket/flight, it actually comes with a seat. Having to "pay" for a seat is just ridiculous and rather embarrassing."
Pros: "The aircraft, crew, and flight were acceptable."
Cons: "I booked this flight online since the price was better than other carriers. I paid an extra $40 for a carry-on when I checked in. Had I understood at the time that I booked that this charge would be required, the fare wouldn't have been better than the other carriers. Between that and the lack of TSA-Pre, I won't fly Frontier again if I have a better alternative."
Pros: "The crew were good people and I like that I got to my destination and back, thank you. Guess I should be happy with those results and be done with the review but I'm not."
Cons: "Seats were smaller than I remember, less space to get into them as well and the tray tables were at first adorably tiny but as the flight progressed it became apparent tray tables were more for show than function. No 'free' beverages available, not even water by the time they reached my section. After paying for a carry-on and to sit (worthy to note standing is not an option) neither of which I was aware of prior to booking, the once-seemed like a deal of a lifetime ticket price turned out to be just about the same cost as other carriers. It has been a few years since I have flown with Frontier, it will be a while before I book again with you Frontier."
Pros: "I like that Spirit likes to board fast."
Cons: "Seats with no space or recliner"
Pros: "Price"
Cons: "I was sick all morning. Got there at 1130 for a 1208 flight. No sympathy. Has to spend money for another one way ticket."
Pros: "Price and the short flight"
Cons: "Middle seats both ways, other seats are upgrades"
Cons: "Worst airline ever"
Pros: "Seat was comfortable"
Cons: "It cost more for a carry on bag than a checked bag."
Pros: "Very comfortable seats, lots of leg room, friendly and enthusiastic service."
Cons: "not being able to have my bag under my seat (I was in front row), had to pay for water"
Pros: "Every time I did something it cost me. You talk about low prices, by the time I paid for luggage and seats both ways I could have gone to a more expensive airline and paid less. Never again"
Cons: "I know Spirit offers low fares and in return you pay for everything else, seats, carry-on bags, boarding passes (if you don't print yourself), drinks, etc. In knowing this I did my due diligence before this flight to make sure I wasn't going to be charged for things like the size of my purse (I measured it), etc. Upon check in for this flight, I was informed that I owed $30 because my checked bag was 43 lbs and Spirit has a weight limit of 40 lbs. The other customers in line were just as shocked. To me, the standard is 50 lbs. With that being said, in my research on Spirits website this was not clear. I think this sort of fee should be much more prominent. I am a "prepar-er" if you will and for me to not know this charge was coming tells me Spirit most likely makes a lot of money off of passengers regularly having to pay this unexpected fee at check in. The ticketing agent told me it happens daily after I asked him. This feels a bit like a scam, in my opinion. Spirit will say "It's on our website" and I'm sure it is but again, I don't feel like this charge for a weight that's standard is 50 lbs is clearly called out to passengers. I'm fine with no frills, I'm not fine with unexpected charges that I feel are under the radar until the 11th hour when you have no choice but to pay or repack. Uncool, spirit."
Cons: "It is impossible to pay for bags at booking at the lower rate. Couldn't get on line payments to work. But they kept trying to get money- for seats, for better boarding, for insurance- it never ended!!! Had to call. They wanted to charge me $100 for 2 bags since they helped me. Supervisor did nothing. Told me I should have booked directly with Spirit to pay for bags at lowest rate. So why do they offer themselves to search engines like Kayak? It all amounts to hidden costs and terrible service. Flight was delayed understandably because of weather in Denver. BUT, since the only way to make our connection was not to get our luggage, they refused to get our luggage on another flight on our connecting airline. Said we'd have to figure it out with Fed Ex. No solutions or help offered. I will never fly Spirit again."
Pros: "$93 vs $150, when we checked in online :) Aircraft was clean and comfortable. Crew was friendly and funny :)"
Cons: "Wish we would have known ahead of time about online check in, for outbound flight! Also, found out about $9 fare club during return flight check in - better late than never :)"
Pros: "Staff were nice, funny, and accommodating."
Cons: "n/a"
Pros: "Nothing, actually."
Cons: "The crew was rude and ineffectual."
Pros: "Friendly, great service."
Pros: "Nothing to brag about."
Cons: "Lack of space, over charged for baggage, delays on both ends of the trip."
Pros: "First we are flying due to a death in the family. We pay $60 per ticket. Next we get to the airport to check in to find out we had to pay for our seats even after we pay for our seats already. Then we find out that our small carry in bags are another fee. $55 dollars for each bag. So needless to say we had questions so we decided to check in at the counter in person. Oh she answers our questions the. Proceeded to tell us that because we checked in at the counter (because of questions and hidden fees) there was another fee of $10 person passenger. So we get onto the plane. To find out that if you want anything including water, it's at lease another $3.00. For water? Are you kidding? Then we get comfortable in a plane that is sized for a small child. The hear not once, not twice, but three times about a credit card. I am appalled to be bugged three times about a personal finance. Jeez. I didn't pay that much money to be sold on a credit card. I would expect this from a time share. And finally when the plan landed it actually rattled. Sounded like the wings were going to fall down off. So needless to say you have lost our business. We will never fly with Spirit again and neither will my family members."
Cons: "Wasn't asked if I wanted snacks or a drink. Drove by the first 4 rows without a word."
Pros: "Nothing"
Cons: "Cost 100 dollars to check in one bag!"
Pros: "Crew made jokes, trying to be nice because we were already delayed"
Cons: "$55 carry on bag fee, expensive drinks, delayed flight."
Pros: "Staff were great; flight was on time"
Cons: "seats are very uncomfortable, very little leg room."
Cons: "Flight to Denver was loud not a good flight attendance Was very poor"
Cons: "My flight was booked for the wrong day. I only had one day selected on Kayak.com so I never thought to call in and verify time and date. I was signed up for text notifications but I never received anything."
Pros: "Hardly any lines Quick flight"
Cons: "Unexpected charges for checking a bag My laptop was lost on the way to Denver via baggage claim Delayed boarding"
Pros: "Got the row to myself"
Cons: "Small chairs"
Cons: "Misleading information about charges for carry-on. I understood extra charges would apply to luggage checked in, not suitcases carried onboard. Leg room is too small for tall people. I am 6'1" and my knee's were pressed against the seat in front of me the whole trip, not comfortable at all."
Cons: "Our flight was ready to depart when it was delayed for an issue that would only take about "20 minutes to resolve". We sat on the Tarmac for over an hour with no updates, in the middle of the afternoon during Arizona's summer. Finally, the allowed us get off the plane, where we sat in the terminal for hours and hours with little to no updates. Eventually, they cancelled the flight, leaving the passengers s rambling to find a new airline to book an entire new flight. I will never fly with them again!"
Pros: "Flight was fine. Economical."
Cons: "Why on earth would Kayak.com send me this question at 12:30 in the morning? I'll probably use Spirit Airlines again, but not Kayak. Boneheads."
Pros: "Nothing!"
Cons: "The plane was delayed! They have all these secret fees"
Pros: "Nothing."
Cons: "I spent 7 hours sitting in an airport with nothing to do spent more money at the bar in the restaurant and with my baggage then with the actual ticket cost plus I made it 9 hours later"
Cons: "flight was delayed. No free beverages. Outrageous to charge for carry-on"
Cons: "The airline couldnt get a mechanic for simple issue for 2 hours."
Pros: "Nothing to like. Have to pay for everything. Worst seats, rude crew, and the charge for selecting your own seat!...come on."
Cons: "Everything"
Pros: "Everything was good"
Cons: "NA"
Pros: "I loved the humor the crew worked into the mundane aspects of flying."
Cons: "I did not like having to pay an additional 45 dollars to bring on a cary on that seemed a bit steep in price point."
Pros: "Overall the web site looks like it was successfully intended to be attractive and it contains all the needed info."
Cons: "*Promising to answer a question "within 48hrs" is NOT OK when it is about checking in. *We SHOULD NOT have to register in order to be able to check in. Why is more than conf # and name needed unless it is to be shared or sold? *The needed info is scattered in many places on the site eg bag size, weight, and prices. *I was charged the "at checkin" price when I used the add baggage link before starting to check in; b/c I was within 24hrs? Purposely didn't start to check in yet so I wouldn't get the higher price."
Cons: "False advertising regarding rates. Price doubled after mandatory items charged. Doesn't reflect what search claims price will be."
Pros: "Delayed 2 hours waiting for paper work really????"
Pros: "Left 45 minutes late due to maintenance."
Cons: "Late arriving at next destination"
Pros: "The crew coming back had a sense of humor. Made it more enjoyable."
Cons: "Still think your luggage rates are outrageous. What I saved on flight the luggage check in rate made it more expensive. Probably won't use you again. Sorry, but money is tight. And charging the outrageoust rates for snacks. Shame on you."
Pros: "On the way back from Denver to Phoenix I did like the instructional Stewart he made it fun to listen to"
Cons: "The fact that you have to buy everything even just a soda or water. You had to pay $50 each Way for a check in baggage. I don't think I will fly Spirit again for those reasons. Had to pay extra for a requested seat. The list is too long."
Pros: "Crew was nice."
Cons: "Delayed for 3 hours!!! Flying out and coming back home, we had major delays due to mechanical problems. No excuse to have that long of delays if they were keeping up with the maintenance on the planes like they should. I will NEVER fly Spirit again!"
Pros: "Low cost"
Cons: "Crowded seating"
Cons: "I could live with the extra charge od $55 per bag on the Denver to Phoenix portion of the trip, but they cancelled the flight an hour before leaving Phoenix to Denver. This left 100 people scrambling to find an alternative flight. Rather than wait 1-2 hours while two totally unprepared ticket counter clerks tried to accommodate 100 PO'd travellers, I decided to get one of the few tickets available to Denver leaving that day. It cost me $375. I finally got thru to the Spirit Customer Service desk (somewhere in the Philipines?) where somebody did try to help, although the line was sketchy and the accent indecipherable. I recommend not listing Spirit on your site."
Pros: "boarding was quick"
Cons: "The counter lady said my luggage was to big. It is the same bag I used on the previous flight with Spirit. WE walked out there and put it in the luggage sizer and it fit. she never left the counter she just yelled. I don't think so. so we had her come out and look. Customer service is lacking."
Pros: "It was a short flight"
Cons: "Waiting in the airport for three extra hours for a plane to come for us."
Pros: "The only thing we liked is that after going to the airport and begging they were able to get us on a United flight."
Cons: "1. Our flight was canceled on a Thursday. 2. They said the next flight they could get us on was MONDAY!! 3. We had a 10 month old with us and nothing was offered in terms of hotel, food, transportation, etc... 4. We had to drive to and pay to park at the airport to talk with someone because they wouldn't do anything over the phone. 5. They finally paid for a ticket on a different airline which was good but we had to pay for bags even though we had already paid for bags on spirit."
Cons: "Flight was cancelled when I arrived at the gate. No notice and no alternative flight for two days."
Pros: "Flight canceled"
Cons: "Flight canceled and didn't offer anything except a refund"
Cons: "Everything costs you. I had never flown Spirit before and didn't know what to expect. They have these strict measurements for carry on. My computer bag was a couple of inches too long, and i was paranoid of having to pay $100 at the gate, if I had to check it. Instead, paid $45, and no one even paid attention. Same went with my wife. Also paranoid about overweight baggage, which cost you extra over 40 lbs. i would rather pay more up front than stress aboit baggage, and pay for a window seat. Southwest has Spirit beat all around."
Pros: "smooth flight, no hangups"
Cons: "The crew told us in the beginning that the toilet at the back of the plane was broken. It was a holiday weekend so I'm sure there wasn't just another plane sitting around to swap out for but it was really inconvenient and uncomfortable."
Pros: "Price"
Cons: "Baggage cost."
