Pros: "Friendly staff, comfortable seats"
Cons: "The flight attendant went on and on and ON about how turbulent air was reported ahead, just because we're in a smooth stretch doesn't mean we're out of it yet, and so on. Must have been every 10-20 minutes. She just would not stop talking; while her voice was fine in person, over the PA it sounded like a cheese grater taken to my inner ear. I barely slept that flight; it was miserable."
Pros: "Staff was very friendly and with a good sense of humor. Food (for purchase) was fresh!"
Pros: "Seats had slightly more leg room"
Cons: "Seriously a coffee pot running hot water kept us on the ground another 45 minutes to an hour, very frustrating. There was one flight attendant Jordan that just made me uncomfortable she seemed rude and short even with her co workers. The food looked like it wasn't worth it on flight. Over all this experience made me second guess booking through Alaska and I'm going with the rei credit card instead too."

Pros: "Professional flight attendants"
Cons: "N/A"
Pros: "Great flight. On time, good weather"

Pros: "Crew gave us updates"

There were a lot of stairs to get off the plane and then walk back to terminal and then a lot of stairs were there to get back to terminal. I was hurting in my knee and my kids ears were hurting badly because the pressure was not controlled while landing. It was a very bad experience and I will definitely think twice about flying Alaska again."
Pros: "Boarding was fast"
Cons: "Space between the rows is narrow, I understand it has nothing to do with the flight itself."

Pros: "That everything was in time. No delays."
Pros: "I am a tall woman and rarely ride in an airplane without my kneecaps brushing the seat in front of me in coach. Not sure what Alaska Airlines is doing differently, but I had knee-room to spare on my flight to Seattle!"

Cons: "A child crying the whole trip behind my seat. No effort by mother to stop child from crying"

Pros: "Good flight as always with Delta. Sat in economy comfort, so of course the seats was comfortable. Flight Attendants were great."
Cons: "Flight was delayed a bit due to a couple passenger booking/misc issues. 1st class didn’t get gate bevfood service. Oven was busted so my meal wasn’t available. Entertainment console had all channels functional except — not really an issue I just really wanted to have ESPN playing in the background"
Pros: "Food was so good. Crew was also very nice."
Pros: "Check in person was very helpful in rerouting our flight."
Cons: "Our flight was delayed 3-1/2 hours. The gate crew booked us in another flight but did not issue a ticket, so after transferring to another terminal, we were sent back to the Delta terminal to be issued a ticket to a third airline since we already missed the second flight. Then, they lost our luggage"
Cons: "It was late"
Pros: "Good crew"
Cons: "The WiFi didn’t work well"
Pros: "Good snack selection. Crew was personable."
Cons: "Seats did NOT recline, which seems to be a pretty poor planning for a red eye flight."
Cons: "Notify the delay quickly"
Pros: "Jeff was our flight attendant in first class. He is an excellent flight attendant. He has an amazing attitude and his manner made us feel as if we had been friends with him for years."
Cons: "Passengers who pay retail for first class on domestic flights should get access to the Delta lounges even without the AE card. Other airlines do this, and we have come to expect it."
Cons: "The boarding process at LAX was awful. I’m sure the horrible shuttle wait and transfer from terminal to terminal is the airport’s fault, but the airline did not do anywhere near enough to inform passengers of what was in store. It was confusing and annoying."
Cons: "They did great. The weather was poor, so it felt more like a roller coaster ride home. Made it safe and sound. Would’ve been nice to get an update is speaker about change in weather and the rough ride in store when the whole ride was so turbulent."
Cons: "I checked two bags and paid for them. The flight was full. I dutifully got in line for zone two. Next thing you know, at least 25 people got to board early and have free bag check. Really? I should get $35 dollar refund."
Pros: "N/A"
Cons: "Chinese Eastern did not try to help and solve my problem."
Cons: "No dairy free options!"
Pros: "From check in from Delta App till receiving luggage, very smooth and painless process. Thank you!!"

Pros: "We had a 2 1/2 delay due to mechanical issues but the crews, flight and ground, did a great job. Thanks."
Pros: "I was still full from flying a Delta international flight from CDG to ALT, so I opted out of all food. They just offered snacks and beverages."

Pros: "My flight was great. Boarding was easy and the seats were comfortable."

Cons: "It was really cramped and the bathrooms smelled very strongly."
Pros: "Nice plane, smooth flight, flight was on time in spite of the disaster in Houston."

Pros: "Seats were comfortable. Snacks!!! Nice flight crew."
Cons: "I liked everything."
Cons: "The plane was about 10 minutes late departing (not too bad), but the Entertainment System was down for the flight, meaning that in addition to entertainment, the USB and outlet charging was not working and you couldn't see current flight status."

Cons: "Unkindness of gate agent"
Cons: "Three bags were left at Paris and were delivered to me only after more than 48 hrs - lock of one bag was missing and other bag was in damaged condition"
Pros: "Definitely can't beat the price, especially for a non-stop flight halfway across the country. I had plenty of room in my seat even with my backpack under the seat. The drink and snack selections are pretty decent."
Cons: "Delayed to start and it took a while for all the bags to be loaded. Once we arrived it took over an hour from the time we touched down to when our bags arrived at the baggage claim. Ended up finally leaving the airport an hour and a half after the time I was originally supposed to arrive."
Pros: "I arrived."
Cons: "It was an hour after boarding before take off. Another 15 minutes on the ground after landing waiting for a gate at midnight on a weekday. I understand that circumstances occur beyond the airlines control, but this has been routinely occurring on my trips with Frontier. Absent compelling reasons, I will not be flying with them again."
Cons: "My brand new Wacom tablet that I received for Christmas was stolen out of my checked bag"
Pros: "They still pick up trash!!"
Cons: "New airbus has even LESS room!! Have to manhandle your personal bag out of the even smaller space under the seat! A soda is $3! There is Nothing to read anymore and the crew are overwhelmed with cranky people... making them cranky."
Pros: "Nothing"
Cons: "Too many fees"
Pros: "As above."
Cons: "As above"
Pros: "It didn't crash"
Cons: "The whole staff from the check in to the attendants was rude rude rude. Never again!"
Pros: "fare was good"
Cons: "the seat was terrible"
Pros: "On time"
Cons: "Seats are very uncomfortable and do not recline. Tray is child size. Entertainment? There is none. Was that a joke topic? You didn't even have a magazine."
Cons: "The carry on price and a kid crying the 2 hr flight"
Pros: "Low fares Smooth ride/landing Bigger leg room than Spirit Airlines"
Cons: "Delayed flight Seats were not the most comfortable"
Pros: "Crew was friendly and accommodating but we waited 3+ hours for a pilot that never showed"

Pros: "Efficient from the crowded baggage check to baggage claim. Great Job!"
Cons: "Seats don't recline, get what you pay for!"
Pros: "Flight attendants helpful and pleasant"
Cons: "Plane was filthy. Crackers, chips, etc all over the floor. Wasn't a clean spot anywhere. Unpleasant to sit for several hours with my feet in filth and to have to put my bag in it under the seat."
Pros: "You got me to my destination."
Cons: "I thought the Stewartists were not friendly at all.. also there is no longer complimentary drinks and snacks.. I already paid 330 for my ticket then they tried to charge for a carry on.. Frontier nickle and dimes its customers"
Pros: "Staff was awesome and efficient"
Cons: "Food options, especially since one has to purchase snacks."
Cons: "Flight was cancelled 30 minutes prior to boarding with no explanation given. There were no other flights on Frontier for two days. There was one single gate agent responsible for dealing with every angry passenger. I had to rebook on a different airline for the next day, and it cost me $250 more. This was very painful, especially during the holidays."
Pros: "My bag was lost in my FIVE HOUR layover in Denver, and no one could tell me where it was for five days. I only tracked it down by stalking some Frontier employees on their lunch break in seatac. I will never fly frontier again. Money saved isn't even almost worth it"
Pros: "I liked that the flight was cheap."
Cons: "That they forgot about 20 peoples baggage in Denver and the day revolved around baggage. I got my baggage later on that night but i had arrived in the morning and if that was the case of me going back and forth to the airport i might as well should have gotten a later flight for that matter."
Pros: "the price. Staff are lovely. laughed at the mini-tablet sized "tray table.""
Cons: "Pity anyone over 5'7" or overweight -- least legroom I have seen on an airline to date. I would fly again squashed on a plane... but I would tell most men, there is no room for them. DVT waiting to happen. Oh gate guy at Denver told me my gym bag carryon was oversize (it wasn't).. guess they are obligated to try to get us to pay for "extras." I did not pay because the bag was smaller than their carryon template."
Cons: "pay for seat on aisle, pay for soda, pay for reclining seat, pay for carry on luggage, reading lite out, no reading for a 3 hour flight, not much in-flight service."
Cons: "Not sure why there even is a flight staff. Airline doesn't even offer snacks. Airline did one round of "beverages" on a 4+ hour flight. The in cabin crew hangs out in the front just chatting with each other (because they presumably have nothing else to do). $40 to put a bag overhead. Seats don't recline at all."
Pros: "The price"
Cons: "I was flying to Seattle with my 8-year old son and my boyfriend. Because Frontier charges so much for bags, we packed all of our stuff into one bag. My bag ended up in San Diego instead of Seattle. I was told they'd refund my baggage fee and I've yet to see the money. We only had ONE day in Seattle before we were going to drive back to Denver. Our one day in Seattle was ruined because of my bag getting on the wrong flight. We were told the bag would be on the next flight to Seattle, which would be 10am the next day. I was told they would call me when the bag arrived. 11am came and went and I spent 20 minutes on hold just trying to speak to an actual person to find out where my bag was. Finally got ahold of someone and they couldn't locate my bag. We decided to go about our day, but I had to spend $100 on jackets and clothing and toiletries for my son, boyfriend, and me. Around 5pm I called again, and also had to wait another 30 minutes to talk to someone. They told me my bag had just arrived, and sorry it didn't make the earlier flight. Now the Frontier counter was closed and they'd only open from 9pm-11pm. Had to make a 30 minute drive to the airport at 9:30pm to retrieve my bag. All around it was a terrible experience and our one day in Seattle was ruined by the bag getting on the wrong flight. Extremely disappointed in how they handled the situation. I don't care how cheap Frontier flights are, I will not be flying them again."
Pros: "The crew were never short or rude at least."
Cons: "Poor handling of delay. Announced a maintenance problem, due to bird strike, which itself is understandable and I certainly wouldn't want to have that rushed, but at one point they said it would only be another 10 min. Ended up being something like a 5hour delay. They wouldn't just tell us it was a significant delay, but instead kept announcing "any minute now." Offered food vouchers eventually, but many of the few places we could use it were closed by then. Stranded in the airport."
Pros: "Nothing at all really..."
Cons: "Flight schedule kept changing at last minute. Seats were uncomfortable. They charge $25 for every bash to checkin including first bag. Also they charge anywhere from $9 to $16 each flight for picking seats if you want to to seat together with your family. I will not travel ever in frontier airlines ever nor recommend it to anyone."
Cons: "The flight was over an hour delayed on the ground and then my luggage is still completely lost. The customer service has been absolutely terrible. I am in a city in which I do not live, with absolutely no clothes, toiletries, shoes etc and I have been on hold waiting to talk to someone about my missing bag for over 45 minutes. Frontier has absolutely no idea where my bag is, it is not in the place that I took off from and definitely not at my destination. This has been an absolute nightmare in which they offer you pathetic $50 to make up for the over $3500 I have in missing belongings."
Pros: "Flight was on time"
Cons: "I haven't flown frontier for about 7 years. I used to love the airline but didn't realize they had changed their model. I was so surprised we had to pay for EVERYTHING even a carry on bag. The seats were uncomfortable and didn't recline. There wasn't a real tray table to do work, you can't get any sort of beverage without paying. I felt nickeled and dimed the entire time. The crew were not very friendly. Also, I was given a $10 voucher by frontier and I asked 3 different employees how to use the voucher and no one knew. Additionally, the frontier website and check in process is not intuitive and very lengthy and frustrating. I would gladly pay more to fly ANY other airline but frontier in the future."
Pros: "Nothing"
Cons: "Everything"
Cons: "Charging for carry ins makes me never want to fly frontier again"
Pros: "Nothing."
Cons: "Everything."
Pros: "Nothing."
Cons: "The added fees are ridiculous. First we are charged for our seats upon check in. Ugh. Then, we were able to bring our small roller luggage at no extra charge from Seattle to Chicago. However, in Chicago, we were told to pay $60 (PER BAG!!!) to bring them with us, which I think is exploitation because looking back, i wonder if they could have gone underneath in storage at no charge. Also, the inconsistency of fees was VERY frustrating. Plus, $60 for a bag is absurd, what a completely ridiculous number. The seats were incredibly uncomfortable. This is the most economy airline I've ever flown, and it was horrendous. I'm surprised these even passed code, the tops felt like metal bars and barely any padding. I felt unsafe in the case there were to be an emergency. I will never fly Frontier again, and I will always warn people about flying this carrier. Nothing good to say."
Cons: "$80 dollars in hidden fees, they charge for cary on, and there was no indication of that when i purchased my ticket"
Pros: "Quick boarding"
Cons: "Paying for a carry-on. No complimentary coffee/water. The pocket in front of me had gum wrappers & other trash shoved into in when I sat down (hadn't been cleaned)."
Cons: "Forgot about luggage charges, seat selection charge and the seats don't recline - pretty horrible for a red eye."
Pros: "I didn't like anything about frontier. It was horrible."
Cons: "I did not like the seats as they were uncomfortable and did not recline. The tray tables were tiny. The price is deceptive as you have to pay for checked bag, carry on, and a decent seat. The inflight refreshments were not complimentary. Everything had an additional price!"
Pros: "Crew were courteous"
Cons: "Seattle to Chicago: Had to wait "two hours' before flight to check our baggage in. Made getting to the air port "3 hours early" as recommended by their email alert to avoid long TSA lines - which weren't - made us waiting in the airport way too long Chicago to Seattle: Same "3 hours prior" alert (the lines again were not long) made getting to and waiting in the airport way too long. Plane was delayed getting to gate and/or they brought a "new" plane in - and had to wait to get it "cleaned up" since the agent at the desk was the only one on duty, she said. Plane left late, sat on taxiway and returned with a "sensor warning" that needed looked at. Left way late in the end."
Pros: "I got one free drink for the delay"
Cons: "No TSA Pre-check even with my Global Entry card $45 fee for carry-on luggage (each way) $16 seat selection charge (up to $55 per seat per ticket) No complimentary soda / crackers (only water) No entertainment onboard Told that the ticket I purchased was a 'low fare' ticket which didn't include ANY luggage, not even carry-on Charging more for carry-on luggage than check-in luggage (there is no labor on the airline side for carry-on, but they made it more expensive for the Customer because they'll generate more revenue)"
Cons: "Flight was delayed by 3 hours. The plane came in and sat at the gate the whole time, and no updates or explanation was given by the ground staff as to the cause of delay or the expected time of take off."
Cons: "The seats are amazingly uncomfortable. Your ticket price is good , until you realize you pay extra for absolutely everything."
Pros: "In order to have cheap fares, Frontier charges fees for EVERYTHING. Carry-on luggage, anything besides water, etc. If you can fit everything you have into a small backpack and bring your own snacks, no big deal. If not, I'd recommend a different airline."
Pros: "Even after a 2 hour delay on a 7am flight, no effort was made to board the plane any faster. Staff appeared uninterested in customers"
Cons: "Frontier is not a customer friendly company!!"
Pros: "In spite of the apparently hard-and-fast rule about exit row seats costing extra, a friendly and intelligent young man at the desk at the boarding gate made an exception for me. I am 6'4' tall and a retired firefighter, first responder, ambulance driver, and former EMT. Having a person well-trained for emergencies located in an exit row seat is a potential benefit for the airline as well as for a tall passenger. Your man made a good decision and I appreciated it greatly."
Cons: "I don't favor the large surcharge for exit row seats, especially after the plane is loaded and there are such seats remaining empty. I would suggest dropping the price at that point to $10 or $20 to fill the seats.At least you would make some extra $ instead of zero if no one feels they can afford the seat upgrade. You will gain many more loyal flyers."
Pros: "Cheap initial pro sing online"
Cons: "Never will fly frontier again. Bought the tickets for the cheaper price posted online. Felt like there were fees for everything. Extremely poor service, took an hour and 15 minutes to check my bag. Extremely understaffed. The plane is extremely crammed and uncomfortable, way to tight of a space for a big guy like me. Extremely dissatisfied."
Cons: "Very unhappy that my price listed on kayak did not include the additional cost for a seat."
Pros: "The pilot talked us through the turbulence and gave adequate and great information. The crew was polite and nice."
Cons: "Overall the food options didn't include an actual meal. That wasn't the specific flight's fault- more of an overall problem."
Pros: "Boarding moved along smoothly, seats were decent enough"
Cons: "I did not have a food/drink menu in my seat compartment, nor did anyone else in my row. When the stewardess walked by, I asked her for one. She rudely snapped at me "well you should have one" and then she walked away. She never came back with a menu. I was so stunned by her sharp attitude that even the girl sitting at the row across from me felt bad and asked for a menu from someone in her row just to give it to me. At that point I didn't even want to look at the menu and I didn't order anything. I probably would have otherwise. I don't know why this particular stewardess acted like that towards me as I had not interacted with her previously nor was I rude at all. All I said was "can I please see a menu? I don't have one." This was my first time flying with Frontier and I will probably not fly with them again. I will stick with United and Delta. I have never been treated like that on an airline before."
Pros: "charge for carry on, no let room"
Pros: "The crew was very nice"
Cons: "The seats were not very comfortable and I had to pay to carry on my bag"
Pros: "Beer was cheaper on the flight than in the airport."
Cons: "Flight was late to board, chairs where uncomfortable and my seat keep being kicked from behind"
Pros: "We were early until we got to the destination, and then sat on the runway for over 30 minutes (contrary to reported landing time) without pulling up to a gate. As passengers we were given very little information which is frustrating when the flight is so late."
Cons: "Spirit could have made a better effort to plan their gates better so planes don’t sit on the tarmac, and they could do a better job of giving passengers information."
Pros: "It was ok, male flifht attendant super friendly"
Cons: "The seats weren't that comfortable for my husband due to his height."
Cons: "They were very nice to me for volunteering to take next available flight"
Pros: "No service issues. Our seats were arranged so the family was together for no charge. We were given a bottle of water to mix baby formula for no charge."
Cons: "Hard seats"
Pros: "Captain of the flight was funny and entertaining, landing down in Seattle was really smooth."
Cons: "The delays were ridiculous; 1 hour delay for the first flight (Seattle to Chicago) and 3 hour delay the next one (Chicago to Seattle)."
Cons: "I didn't like having to pay my bag twice. My flight was delayed 2 hours causing me many issues upon my arrival."
Cons: "Flight attendants were very rude, for no reason at all. I had no idea the seats did NOT recline. After paying for your bags and seat selection you are better off flying on a typical airline. We flew Chicago to Seattle, we are not big people, but a 4 hour flight is claustrophobic with this airline."
Pros: "the funny jokes by the flight attendant"
Cons: "there was a fee for EVERYTHING!"
Pros: "Utilization of Kiosk, check-in, boarding, crew, and pilots. The seats were clean, too. Thank you very much :) !! Flight was also on-time for departure and arrival at destination. * In the Review, put my name as Anonymous. Thank you."
Cons: "Prices for beverages, food, and/or snacks are extremely HIGH! $3 USD for a 12 oz. can of pop OR WATER (16-20 oz) ? ! ! $7 USD for a 5-6 oz bottle of wine ?! The prices are ridiculous!! You can't get water to cry with or if you were on fire. Upon viewing your menu, there is a "bundle" for three or more items. This IS NOT a bargain. You decrease the price by a dollar is nothing. It appears to be overly enrichment and a rip-off. I know that you're in business to make a profit. But dayumm!! REALLY??! You all are certainly taking advantage of your customers. There may be either a continued decrease of purchases or none at all. I noticed that there weren't many purchases in relation to the number of passengers on board at the time. BTW, the price paid for the single bottle of wine ($7 USD) is what it costs for the 4-pack, if not less. A person can purchase 750 ml or 1/5 gallon for the same amount or less (i.e., $5 USD + tax). This is wrong and obliges passenger to make a grudging purchase out of necessity. Have you ever been thirsty before? Can't have water to take medications without spending large amount of money. You can't even get tap water or courtesy cup of water / ice. What type of mess is this? $50+ bag check fee is horrendous!! Your competitors are much cheaper. Please add more cushion and room to your seats. Had this flight been more than 90 mins., I'd be making a trip to the hospital instead of home."
Pros: "Flying with spirit airline is like driving the cheapest, smallest und most unsafe car and hearing loud noises everytime you accelerate. It is by far the most uncomfortable flight (3.5 Hrs) I have ever been on !"
Cons: "The list is endless. Safety comes to mind ... Did not feel safe sitting in a lawn chair and the life jacket underneath my seat was tiny . Will not fly with this airline again. It is cutting too many corners to offer a cheap rate"
Pros: "Can only rate on everything but Entertainment & Food, since there was neither of those. Other than those it was 5 Stars all around."
Cons: "No complaints available."
Pros: "Great for anyone simply looking to get from point A to point B - no fuss!"
Pros: "the service is good, schedule is on time, and the price is very cheap. It's a good choice for a 2-hours flight."
Pros: "I love the comedy flight attendant!!!"
Pros: "No way to contact wheelchair assistance when being dropped of to begin flight. Waited 30 minuted for a wheelchair. Had to ask Amer.Air agent for help. Other airlines are far more attentive. Seats need 2 more inches, felt squished. Very costly baggage policy, charge for carry- ons."
Pros: "Bording was fine"
Cons: "Horrible costomer service, nobody knew there job. Never flying spirit again"
Cons: "Seats did not recline ( the whole plane - not just exit rows). All the extra charges for EVERYTHING were ridiculous, especially as you are not informed of any of them before booking. I'll not fly Spirit again."
Pros: "Friendly staff, fast flight, and no frills fares. They'll charge you for drinks, etc., But overall a good flight."
Cons: "Uncomfortable seats, no free water."
Pros: "Glad I tried spirit! Got me in early on both legs of my flight! Also glad I got the comfy seat-SO worth the money!"
Pros: "Absolutely nothing!"
Cons: "This is the worst airline. Extremely chaotic boarding, it seemed like I was in a third-world country. Nothing about this airline is good. They lure you in with cheap airfare though when you begin to add costs for everything they charge separately it's cheaper to fly AA or United or Southwest. The charge for WATER on the plane. The list of everything I don't like is too long for me to waste my time on this most substandard of the substandard airlines."
Pros: "The flight attendants were friendly"
Cons: "2 hours delay and not provided any explanation and very few updates during the wait. No offer of compensation, even the full charge for luggage was still requested. The lengthy solicitation of the credit card was tacky."
Pros: "Change of gate wasn't fun but it was handled professional."
Cons: "Slightly less expensive ticket not worth it. $52 for checked bag. $56 for carry on bag. They charge for a plastic cup of water on flight. Seats have no leg room and do not recline. Poor communications at gate. Few gates for Spirit, so if flight is delayed, plane has nowhere to let passengers off when landing. We were already hours late, and then had to wait 45 minutes for a gate once on the ground."
Pros: "No entertainment on the flight and we didn't have any food. Flight was a direct flight. Everything went smoothly. Actually arrived a little earlier than scheduled. Didn't have to wait too long for our luggage."
Pros: "Of the 6 flights I took with Spirit on this trip, this was the only one where they boarded the flight in a timely and organized manner by using the zones printed on the boarding passes."
Cons: "Spirit airlines cancelled my flight the day of travel."
Pros: "Nothing. I was treated so poorly I walked away from their customer service and bought a ticket on another airline."
Cons: "I was 5 minutes late over their 45 minute required check in window. So they cancelled my ticket. For $100 they offered to reschedule me. And for another $50 they would check my bag. On a different airline I paid another $100 and got a complete round trip ticket, about 10 minutes later."
Pros: "Good Pilot good Landing smooth ride"
Cons: "This crew was also unprofessional I did not feel comfortable with them"
Pros: "The crew was nicer on this flight. They made more of an effort and the temp was much more comfortable."
Cons: "They don't give you water or snacks. You have to pay to pick your seat and CARRY ON your luggage. The hidden fees surpass the cheap flight"
Cons: "Flight was delayed over 3 hours for no apparent reason."
Pros: "Nothing except the price"
Cons: "Delayed boarding"
Pros: "The crew on this fight was good."
Cons: "I got there early to check in, only to have the ticket agents continue to call customers of other flights, such that I barely made it on time for my plane. To boot, there was a Spirit ticket agent just standing there doing nothing behind a computer while there was a super long line. People started to go up to her to ask questions, and then she was helping them with tickets using the computer. Then she started to help people in line. She just stood there for about 45 minutes doing nothing though. Ridiculous. I'll never fly this airline again."
Pros: "Low cost base ticket"
Cons: "Baggage fees added 80 to the flight cost and seat fees would have added another 40 if I paid them. If I knew that when I bought the ticket I would have gone with another airline. Oh, and no TSA pre-check option at O'hare"
Cons: "they were rude and uncooperative. They have no type of customer service. If you ask them a question they are short and direct. If you try to work out to find a solution...they just are plain rude and do not make an effort whatsoever to accommodate their customers. They abide by their ridiculous rules and plainly will not work with you. Besides that they started to charge for separate baggage fees. So you'll but a ticket for "cheap" but then they will charge you double for baggage both ways. My boyfriend purchased a ticket and wanted to make changes...they wanted to charge him $100 to change flight info. RIDICULOUS. He ended buying another ticket....Spirit took $200 in fees extra from us."
Pros: "Everyone was very nice and the check in process was easy."
Cons: "The seats were not that comfortable and I didn't like that food wasn't included but it was a short flight so it was OK."
Pros: "Once we finally had a plane, it was fine, we boarded and took off for home and the flight was great."
Cons: "delay, delay, delay, delay...yes, 4 hours late. Not sure why, but this flight was delayed by 4 hours. I don't know if there was anything they could have done about it, but it was terrible being delayed so long."
Pros: "Nothing"
Cons: "The airplane was dirty. And, a woman next to me asked for some water and the flight attendant says, "$3 for a bottle." This is very disrespectful and classist. Not everyone has $3, and I could tell that she didn't. Also, the plane made a terribly loud noise. I feared for my life! The flight was delayed but the crew did not give us updates.... We simply waited. And waited."
Pros: "Nothing"
Cons: "The flight was delayed with no reason given, the tray tables were too small, the seats were too narrow"
Pros: "I was very surprised to get charged $55 for my standard carry on. Spirit needs to show this on their web site with big letters. I will not fly with them again"
Cons: "To get charged for carry on bag"
Cons: "Got bumped from flight because it was oversold. Personnel helped find flight on a different airline the next day. But that was not a direct flight and it was a major inconvenience to arrive a day later than planned."
Pros: "There was nothing that i liked ."
Cons: "Seats do not recline. Excessive charge for carry on luggage - $45 each way Bait and switch tactics by pricing the ticket price low and then charging for EVERYTHING. Flight crew has nothing much to do but stand around and gossip"
Pros: "NOTHING"
Cons: "Everything with spirit is terrible. The trick prices (you think it's cheap??? Not if you want a seat, a bag, a drink, to breathe!!), the terrifying folding chair seats, the horrible leg room, the worst service. Now I remember why I NEVER should EVER fly spirit."
Pros: "They try to get money in every way possible. They give you a good price on the flight ticket and then they get you on your luggage in a terrible way. 40 pounds instead of 50 like every one else. You have to pay for the carry on as well. They won't even give you water. First and last time with them. No thanks."
Cons: "I hate their crooked way to do business."
Pros: "we flew from oakland to ohare for the first time on Spirit airlines and we were very impressed. We left on time - or even a minute or two early - and landed safely. what more could we ask? The staff was friendly and the plane was clean. two thumbs up!"
Pros: "Met some pretty cool people in the seats next to us. Bathrooms were clean, easy to use, and easy to access. They had a bathroom light viable to all passengers to see whether or not they were occupied for all 3 bathrooms, which I really appreciated."
Cons: "My only complaint was that during our layover in Chicago we couldn't get off of the plane to get food. Eventually we just bought food on the flight because our trip in total was about 6 hours of flying. I wish there was more food options. Oh, and the crying baby behind us wasn't the best either, but we drowned it out with conversation."
Pros: "Crew and flight was very good"
Cons: "This was the second time I flew to MN with Spirit first time my return was cancelled and this time was delayed by an hours and delayed take off and delayed at Ohare"
Pros: "Nothing"
Cons: "Flight was delayed several hours. The staff did not inform us of the several delays. Only notification that was given was a gate change. We didn't have a pilot so we sat in the plane forever. Horrible service, but u get what u pay for with with spirit. Learned my lesson and will pay little extra to not fly spirit airlines."
Pros: "Check in at the airport was fast (no line)."
Cons: "I was charged $12 for my seat like it was an upgrade- tiny seat that didn't even recline! Most uncomfortable I've ever been on a plane. I was also going to be charged $52 for each checked bag...??? When I told the woman at the counter that it was $31 online she was nice enough to only charge me that much, but what is that all about??!! My bag was 29 pounds, no where near the limit- $52??!! Ridiculous. Staff wasn't rude or anything but they weren't friendly either, just kind of blah. No in flight entertainment, not even free water. Not a great experience. I'll spend the extra money next time to be comfortable."
Pros: "The big seat that I upgraded to for $35 one way was nice - essentially a business class seat. The crew were helpful and pleasant, and the boarding process was well-organized."
Cons: "If I had known the philosophy of this airline ("bare fare" plus pay more than average prices for all other upgrades, including water on the flight), I never would have booked with this airline. Checked luggage is more expensive with Spirit than with other airlines, and fees are almost double at the airport if you don't pay ahead of time. Carry on bags are also an extra fee; only your personal item is free. If you have orthopedic challenges and a long flight, pick a different airline - only the extra cost seats ($35 each way) recline at all. This airline was more expensive to fly than the airlines I normally fly, once I added what I consider to be basic needs. It would have been nice to have this information (especially about the seats) available when I booked on Kayak."
