Cons: "Plane wasn’t clean (trash at my seat)"
Cons: "Boarding got very weird. Having B, C and D boarding groups, all of which sound the same over a loudspeaker, made for some confusion."
Pros: "Seats were comfortable and did not feel confining. Takeoff and landing were very smooth."
Cons: "Having a male flight attendant wearing makeup was off-putting. A gluten free option for snacks would be nice."
Cons: "We were sitting in first class. My husband went to use the restroom in our cabin and the female flight attendant told him to go back behind the curtain and use the bathroom assigned to his cabinet. He is Colombian and she surely profiled him, as I saw two other passengers from coach use the first class bathroom with no concerns."

Cons: "Higher bagge fees and missed the bus"
Pros: "Staff was friendly. Very apologetic about the delay. Offered accommodations that were within reason."
Cons: "There was a delay. Which is understandable and not the airlines fault, but I feel like there should be a more specific boarding process and exit process, especially since there were so many people near missing their connecting flights. Understandbly there is only so much an airline can do, but it can really frustrating when the staff says “seats #-# board and everyone rushes on like a heard of cattle regardless of number. Similar exit experience."
Cons: "I had only 40 minutes to get to my connecting flight. Then the plane was 15 minutes late. They wouldn't switch me to a seat that was open closer to front of plane and my bag was lost w important things in it that I need for this evenings show. I'm a full time musician."
Pros: "I checked my baggage with ease.The whole trip was without any inconvience. My daughter in CO made my reservations both ways thru you. I appreciated the great $fare. We will use you again . Thank You, Merry Christmas!"

Pros: "Seat room"
Cons: "Gate at Seattle airport was crowded. Not airlines' fault but it was tough to navigate Seattle airport."
Pros: "Dexter Alaska agent in Seattle helped get me to Portland then Medford a day late."
Cons: "Denver agents seemed not to care at all and said I could not get a hotel voucher in Seattle. Phone agent said I could get a hotel voucher because it was mechanical failure. arrived late late late into Seattle to be told there were no hotels available. I had to be insistant to get agents to make the effort to get me routed. They to me I would have no hotel and then wait until 5 pm the next day to fly to Medford. They gave no food vouchers. I had to pay for a hotel I never slept in in Medford and meals. Seems like Alaska has few flights out of Seattle and Denver and no other partner agreements to help route you. Really horrible bad experience. Not what you expect when you patly $500 plus trip insurance. Pathetic."

Pros: "Love how fast we all boarded and were situated."

Cons: "I paid for a window seat and the seat next to it. I ended up with two aisle seats. This meant my grand-daughter and I were not sitting next to each other. NOT ACCEPTABLE"

Pros: "This is my first time flying Alaska. I was really impressed when one of the flight attendants offered to hang up my sport coat, even though I was sitting in coach. She even brought it to me at the end of the flight. Service was excellent, the plane was newer and very comfortable. I am a pretty dedicated fan of another airline, but after this experience I will certainly consider Alaska for future flights."

Pros: "The pilot was very friendly and made sure to point out landmarks as we flew over."
Cons: "The boarding crew in DIA was less than friendly, forcing people to gate-check their carry-ons. She used the claim that the flight was overbooked and 20 people needed to check their bags, then threatened to randomly take them. Meanwhile, 60% of passengers were boarding without roller bags. When I boarded the plane, which was almost full, at least half the overhead bins were empty. I had already gate checked my bag to avoid a confrontation with this pushy lady. Ridiculous!"

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"
Pros: "Good crew"
Cons: "The WiFi didn’t work well"
Cons: "Seats did NOT recline, which seems to be a pretty poor planning for a red eye flight."
Pros: "On time flight, bag made it, great price, can’t complain."
Cons: "Seat pretty tight for an average size adult man. No inflight phone charger."
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: "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."

Cons: "Left about 2.5 hours late because of a broken seat of all things. Apparently Delta doesn't bother to have maintenance staff on site at the airport."

Cons: "The Shanghai airport did not open luggage drop off until 3hours before my flight when I was told it would open 5 hours prior, as well as tried to get me to leave to rent a hotel for the night as my layover was a few hours, then delayed Seattle boarding for over 45 minutes, once we were on the plane we were then told we were number 25 to leave therefore leaving us another hour and a half of a delay."
Cons: "I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER."

Pros: "Comfortable seats, good legroom."
Cons: "Not enough coffee for breakfast."

Pros: "The flight was fine"
Cons: "Both flights each way where delayed significantly"
Cons: "Charlotte to Seattle flight: The food served in first class smelled awful. Seated in premium seating just behind first class was unfortunate due to the atrocious odor that lasted for 3+hours. There was no option for food service for the rest of the plane. Which was unfortunate as I was very hungry. Due to inconsistent notification that the plane was delayed / on-time (kept switching the notification) we opted to not get dinner in the airport..... To which the plane was was an hour late yet we were told to check in every ten minutes to see if we were boarding. There were no blankets. The plane was incredibly cold. The suggestion I received from the flight staff was to turn off the vent above my head (which I had already done.) I had brought a jacket and was wearing pants. On a 5.5 hour flight, the crew served beverages 45 minutes into the flight (per usual) and handed out a pretzel pack. They didn't come back through with water or beverages again. On other airlines, they promote water at least once an hour to keep swelling and dehydration down. Since I am a pretty frequent flier, I bring my own water. Still, coffee would have been nice. Suggestions: increase beverage service to at least twice / 5.5 hour flight and provide blankets upon request. Food choices and entertainment would also be good. Don't cook stinky dinners in first class and allow it to pollute the rest of the plane."
Pros: "Space security manners"
Pros: "Seats were comfortab"
Cons: "The flight attendants, could have been a bit friendlier"
Cons: "Broken seat and terrible gogo video experience with an attendant crew that was dysfunctional together for food/beverage service. I prefer to not fly AA."
Cons: "The new seats were so uncomfortable, I couldn't sit shoulder to shoulder with the people next to me"
Pros: "Great service. Lots of legroom"
Cons: "None"
Pros: "Nothing"
Cons: "Service was the worst. The poor training of the staff, is clearly a result of poor commitment by the company to provide good customer service."
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"
Cons: "I just don't like being charged $40 on top of the fare to bring a carryon bag that fits above seat, this should be included in price and still have reasonable air fare. I chose this flight because of the fare then got hit with the extra charge for my carryon and we did not even get any pretzels or chips to snack on either for free. You have to buys snacks, not even a complimentarty snack, so because of this I will most likely choose to fly Frontier Airlines anymore. The flight was great though. Very efficient and timely and the Pilot was fantastic in his take off and landings. Very smooth."
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: "The same"
Pros: "As above."
Cons: "As above"
Cons: "DID NOT like having to wait in Denver airport for the scheduled 9 hour layover and then delayed for another 1.5 hour for a total of 10+ hours. DID NOT like getting lured into a great schedule in March and then in May you cancelled the flight and we had a 9 + hour layover. TERRIBLE. Will never fly with Frontier 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"
Cons: "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: "Staff was awesome and efficient"
Cons: "Food options, especially since one has to purchase snacks."
Cons: "From the time my flight sat at the gate for 30 minutes saying that had to load last minute bags, to getting no water to drink for 3 hours, to uncomfortable seats that do not push back, and now no bags after 36 hours after paying a $40.00 fee, with no way to communicate with the airlines for a status, this will be the last Frontier flight for me, regardless of the pricing."
Cons: "I felt taken advantage of by the surcharges."
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: "The plane didn't crash. That was the only positive."
Cons: "-Both flights delayed by hours to and from, with zero explanation from staff, nor any acknowledgment or sympathy for all of us waiting 4 extra hours to board a flight. -Seats don't recline, trays barely large enough to fit my iPhone on it -Hidden fees with everything. 1 carry-on costs $35-$60, picking a seat costs $9-$35, and you can't even get a glass of soda without paying. Cheaper to book elsewhere after all the extra expenses. -I would recommend horse drawn buggie before flying Frontier. The risk of dysentery is a better option."
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."
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."
Cons: "Flight delayed again, upon arrival in Seattle we were unable to find our car seat. The Frontier rep was not upstairs nor at the carrousel even after being paged by the port of Seattle. Eventually, we found it in front of Delta's baggage claim with no bag on, no indicator (signage) at all that it was part of Frontier's flight."
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: "Nothing"
Cons: "Everything"
Cons: "Charging for carry ins makes me never want to fly frontier again"
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)."
Pros: "The announcement (although I didn't take them up on it) to offer two domestic round trips if I'd sign up for one of their Mastercards. It's probably not a bad deal for someone who likes to have lots of credit cards and doesn't mind annual fees, I'm just not one of those people."
Cons: "My inability to access their e-mail offers to set things up ahead of time and at lower costs than paying them at the airport check-in, above and beyond the baggage charges themselves (Seventy bucks), especially for my carry on ... COME ON! I've become used to Southwest's far more enlightened policies, which I obviously prefer. Since it also has flights between Seattle and Denver, I'll look much more closely at staying with them the next time I make this trip."
Pros: "Airline ticket cost."
Cons: "Rude flight crew and the only thing that doesn't have a fee attached to it is the use of the bathroom and drinking water."
Pros: "Nothing"
Cons: "We had to pay extra for the carry on."
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: "The crew was helpful. And we landed safely."
Cons: "The period between landing on the runway in Denver and arriving at the gate was ONE HOUR. The time it took to claim our luggage in Denver was 45 minutes. I hear Alaska Airlines has a real nice service."
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: "Brutal turbulence leaving Denver. We noticed a crack in the wing upon landing in Denver. Rudeness seems to be a prerequisite for Frontier flight attendants as they charge for water and carry on bags. We refused to pay the additional $13 to select our seats and as a result were seated on the last row of the plane. Kayak should really add the cost of seat selection, a carry on bag, and water to the price they are showing to be more realistic."
Pros: "The crew was professional and curtious."
Cons: "If you're going to charge people for things like carry on, and seat assignment there's no chance you'll ever be my go-to airline again. If you are going to charge that much, at least give me a free cookie, include a tv on back of my seat. Most of all, give the the option to recline my 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: "See cooment above"
Cons: "See comments above"
Pros: "Arrived"
Cons: "Terrible seats, noisy plane. Extra charges"
Pros: "charge for carry on, no let room"
Cons: "It's just really hard to enjoy a flight when you feel like you've been nickeled and dimed. I flew frontier a couple years ago and felt the same way. I forgot I guess and gave it another try. I"m definitely done with Frontier"
Pros: "The crew was very nice"
Cons: "The seats were not very comfortable and I had to pay to carry on my bag"
Cons: "My name was not correct on return email documents. When I tried to correct on-line, the program asked for another $139. When I phoned the number listed, I had a gentleman whose English was very hard to understand. He ended up telling me not to worry about the error-it would not cause a problem. I ended up phoning a 2nd time, to another person to assure that nothing would go wrong at boarding time."
Pros: ".It was a very confortable flight and right on time.."
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"
Cons: "All Frontier flights were cancelled for 2 days straight, therefore I had to book with another airline."
Cons: "My mother did not get one of her bag back when we arrived in Seattle"
Pros: "They took my bags"
Cons: "They lost my skis It took 30+ minutes for anything to disembark. They loaded another plane before moving any of our luggage to the"
Pros: "It was ok, male flifht attendant super friendly"
Cons: "The seats weren't that comfortable for my husband due to his height."
Pros: "Overall ok flight."
Cons: "Dirty Seat doesn’t recline Seat doesn’t have head support on sides No movies No phone charger Small food tray Poor food choice No free water"
Pros: "Again, smooth and uneventful...!"
Cons: "n/a"
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: "Everything!!! Super impressed!"
Cons: "That I had to leave the amazing experience and go on vacation. :("
Cons: "Too short a flight for entertainment"
Pros: "Bording was fine"
Cons: "Horrible costomer service, nobody knew there job. Never flying spirit again"
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."
Cons: "Flight was cancelled without explanation. Found out at the airport instead of text, email, or call beforehand."
Cons: "Food was too expensive, all extra charges were over $400!"
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: "I got to sleep and I got the window seat."
Pros: "Good Pilot good Landing smooth ride"
Cons: "This crew was also unprofessional I did not feel comfortable with them"
Pros: "favorite flight schedule from Den to FLL or visa versa...Thanks"
Cons: "Flight was delayed over 3 hours for no apparent reason."
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: "Direct flight"
Cons: "Lack of customer service and attempt to charge for every little thing possible."
Cons: "Unexplained delays. Then finally someone says the pilots haven't arrived. They still decided to board us, but apparently they couldn't turn on the air until the pilots arrive, so we cook in there, not knowing how long this will go on. Finally, the pilots arrived. Air turns on, but still we wait. And wait and wait, all the while Spirit sends me a total of FOURTEEN delayed takeoff and arrival emails. As if I couldn't already get the gist sitting on the plane waiting waiting waiting. Finally, we get rolling, but never is there any acknowledgment that we've been waiting or that they're sorry for the continued delays or something nice yadayadayada. Last Spirit flight I'll take."
Pros: "Fast easy boarding."
Cons: "Crew would not let us move to open seats that would give more comfort."
Pros: "It was not bad but it could have been a lot better"
Pros: "Friendly crew and fast boarding"
Cons: "No reclining seats, very uncomfortable"
Pros: "I guess it's not your fault, but there was a guy harassing a lady in the returning flight."
Pros: "Smooth flight Cheap"
Cons: "Delayed an hour Spirit had to file for clearance to depart by hand"
Pros: "it was sufficient"
Cons: "charged for bag at check in."
Pros: "Nothing"
Cons: "Nothing"
Cons: "Personal baggage size is too small even for a day's trip."
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."
Pros: "nothing!! Worst flight I've ever had!!"
Cons: "Hated everything horrible service and delayed 4 hours with no weather never riding this airlines again!! What a rip off and they charged me almost 100 bucks for on carry on there and back"
Pros: "I truly didn't like anything about my experience with Spirit. Terrible airline."
Cons: "Flight from Phoenix was delayed. Takeoffs and landings were rough."
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: "My round trip ticket was $150. Great deal except for the added $100 for my check in luggage! Which would have $110 if I would have carried on a bag! Ridiculous! For that price I could have taken another person with me! Next time I should just wear all my clothes I would normally pack and check nothing in! LOL!"
Pros: "Fast boarding, but then we sat with the door open for 20 minutes. Flight was fine. I would only ever consider flying again if there was a phenomenal price break from the next cheapest airline."
Cons: "Gate change with no announcement or change on departures board. Late takeoff. Tiny cramped seats, and miniature tray tables. Trash in front of my seat at boarding. The majority of passengers seemed to be inexperienced flyers, maybe gravitating towards the cheap fare? VERY annoying, needy, chatty, panickey at take off and landing. Not a pleasant environment."
Pros: "Staff was great!!!"
Cons: "Would like a little more room in the seats.. don't really like eating my knees for lunch.. paying for a seat after already paid for your flight is ridiculous.. also, paying $50.00 for check bags and $55 for a carry on is outrageous.. oh and 1 more thing.. no free beverages.. Really.. Come on.. $3.00 for a Coke or water??? Really??? The flights are cheap, but they stick it to you with there added fees as mentioned above!!!"
Pros: "Nothing"
Cons: "The policy for paying for carry on baggage is confusing because you can carry on the same weight and cubic inches as baggage that you have to pay for as long as it is two parcels instead of just one. I will not be flying Spirit again"
Pros: "I will never fly with them again."
Cons: "Customer service was aweful. Women at the front would not allow my ticket to be printed however I was already checked into my flight. They are crooks trying to squeeze money out of their travelers. If this isn't taken care I will no longer purchase from kayak either. I have been a long standing customer of yours. It's the only app I use to purchase tickets. I am now missing work and was forced to pay 100$ to get a later flight. Very disappointed."
Pros: "Cheap"
Cons: "We were delayed over an hour, with no support at the gate to explain why or let us know when we would be leaving. Incredibly frustrating, as I booked this flight (instead of another airline) for the departure time. Would have rather used another airline.."
Pros: "Flight was delayed. Could of been better"
Cons: "Delay of flight"
Cons: "Did not travel on flight due to delay in Dallas. The flight from Los Angeles had left by the time my flight from Dallas had landed."
Pros: "spirit was late both ways. three plus hours late on the way home... so much so the train back into the city was closed and i had to take a $50 cab. i like the idea of cheaper fairs for simplicity, but its worth paying more if spirit cant even get the basics right."
Cons: "spirit was late both ways. three plus hours late on the way home... so much so the train back into the city was closed and i had to take a $50 cab. i like the idea of cheaper fairs for simplicity, but its worth paying more if spirit cant even get the basics right."
Pros: "ticket price"
Cons: "that i was not offered water to drinkq."
Cons: "They will charge you to breath on the flight. Don't get tricked by the low air fair, the extras will equal to more than any other flight you would've taken. $34 for checking in a bag, $32 for carry on. $5 for a soft drink on the plane. The customer service is also horrible all employees are extremely rude and don't care about you. I will never fly with them again and I suggest you shouldn't either."
Pros: "My flight was canceled indefinitely the night before the flight a) without any heads up and b) due to thunder and lightening, it was the ONLY 6am flight canceled. It's unacceptable to conduct business this way, and to no accomodate as a result. I was left completely screwed over to pay ASTRONOMICAL fees to get home for a family wedding I was in. To rub salt on wounds, Spirit's employees (very tall thin man, young to middle age, on the left far desk) along with one other, were rude, unhelpful, condescending, unprofessional, the list goes on. Spirit just lost a very loyal customer who always stood up for the company name. I expect and deserve better. Guess I'll go to Frontier."

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: "In general we like everything, our boarding process, the crew"
Cons: "Maybe need bigger seats"
Pros: "I got a bigger seat."
Cons: "You have to pay for everything."
Cons: "The Flight was delayed for 7 hours but through out the process there was no clear information when we would be able to fly. So it was hard for us to make a decision on what to do. The airplane we were supposed to ride arrived 6 hours late at 12:00am and they told us first that if we dont board by 12:30am the flight will be canceled and rushed us to the changed gate. Then told us because of inspection that the flight will leave maybe in an hour. We ended up boarding at 1:30 and the flight attendant had no regard of our situation. She made loud and unnecessary PA annoucements such as "now we will dim the lights for your comfort so you can rest well" after the plane has been in the air for 40 minutes. Just overall a terrible experience. I understand now why the price is so cheap."
Pros: "The boarding process was smooth and we took off/ landed on time."
Cons: "The crew was complaining as we were boarding about how tired they were to each other and not really helping guests. There was a crying baby for a long time on the red eye and I felt they could've offered the mother some help but they didn't do anything. Then the mother tried to stand up after we had landed but before the seat belt sign had gone off and the stewardess freaked out on her. Could've handled the situation much more professionally. The seats suck, the tray tables suck, not having a complementary beverage sucks, and paying for carry on bags sucks. But that's Spirit and everyone knows that is why they suck."
