Cons: "No delays. And have the terminal bridge in working order"

Pros: "The crew did their job. Some attendants were very kind, helpful."
Cons: "Food could be better. Old aircraft, old style seats. Other airlines have improved this very, very much. Delta is lagging behind."

Pros: "Let's start from the beginning. The flight was delayed for over an hour. Despite guaranteeing anyone with a connecting flight would all be taken care of, here I am still stuck in Amsterdam airport... delayed another 10 hours. The service after arrival was poor and slow..2 hours to get new flight"
Cons: "The travel agents assisting should have been ready for the number of passengers and triaged accordingly. They did not. Which meant a lot of us standing in line for hours missing new connecting flights."

Pros: "Nothing"
Cons: "The three hour delay, the not having a pilot which delayed us even more, and then reduced service during the flight because they rushed us."

Pros: "Free messaging during flight was REALLY nice!!! Smooth flight, early arrival, good coffee, variety of drinks, entertainment system worked very well and fast."

Pros: "Food and service was amazing."

Cons: "One stewardess was in a mood but otherwise a very pleasant flight."

Cons: "Had a seat that did not recline...not broken just one of those seats."

Pros: "Fast boarding"
Cons: "Seats are too crammed and uncomfortable."

Pros: "Crew was wonderful, fine flight, very prompt"
Cons: "Was unable to board an earlier flight without paying $75. If there are seats it shouldn't be so difficult to be moved."

Cons: "Got in early"

Pros: "Pleased we upgraded to comfort plus."
Cons: "It was an older 747 which didn’t have power to the Sears. The video system was also old with poor quality."

Pros: "The plane wasn't cramped, the flight staff was helpful, and we got to our destination extremely quickly. And they gave us like two rounds of snacks which is unheard of on such short flights. Easily the best domestic flight I've ever taken."

Pros: "Seats were comfortable ... enough. Boarding process, once underway allowed me to get overhead bin and stash my other luggage in the seat below me. Flight wasn't overly booked (85-95%) so there appeared to be room for others to stretch out. Now about that crying kid..."
Cons: "Ugh. Weather delays. The flight was scheduled to board about 7P but it arrived late and they had to not only unload the self-loading cargo, but clean up afterwards. Would be nice to get a better estimate as to how long it would take to board so that I could hang out in the lounge. In addition, departure from JFK was delayed as well, either we missed the IFR window or got stuck behind some traffic and I fell asleep on the plane only to wake up what seemed an hour later just getting ready to hit V1. No upgrade."

Pros: "We were not happy with our flight my flight got cancelled 3 times I miss work they need to reimburse us and also reimburses the hotel cuz we had to stay at a hotel because they cancelled our flight three times and then our flight that we went out on Monday was late because of a flight attendant arriving late to the hotel to the airport"

Cons: "In flight staff were rude and had poor attitudes. Very unexpected!"

Pros: "Maintained high standards of service despite massive delay."
Cons: "Boarding and departure was messy because of the delay"

Pros: "Very nice and friendly crew were very efficient."
Cons: "Very nice and friendly crew were very efficient. Unfortunately, we had to wait over 20 minutes to get into our gate because another plane was there, so we arrived late. Not DELTA's fault."

Pros: "The crew on Delta create a welcome atmosphere every time I have flown with them."

Pros: "The crew was very friendly and kept making rounds with water so we didn't have to get up looking for it. Free entertainment at our seats made the flight go by faster."
Cons: "No complaints, I was stuck in a middle seat but somebody has to sit there!"

Cons: "Zero communication to the passengers as to why we were delayed for almost an hour sitting on the plane"

Pros: "My Delta flight was a code share with Virgin Atlantic. A pleasant flight overall with my first impression being an airline with current popular music playing in the background and flight attendants cheerful. Since I was traveling alone, I opted to not purchase my seat prior to my flight date, instead I chose my aisle seat within 24 hours for free. I checked in my one bag and found out I had pre-checked so my security check went so smooth at the new terminal 2 at LAX. Looking forward to my flight back on June 15."
Cons: "Had a toddler behind me crying and screaming the last 40 minutes of landing into Heathrow because she couldn't sit on her mother's lap and made it quite unbareable for all of us in the vicinity. Wondering if there was an alternative way to handle the situation."

Pros: "COURTESY"

Cons: "No space."

Pros: "Seats were comfortable"
Cons: "Provide coffee at least"

Cons: "4 hour delay for no reason! I’m never flying with American Airlines again!"

Cons: "50 minute wait for a gate to deplane. How could there not be a gate at 10:30 pm? It’s not like our arrival was a surprise!?"

Pros: "Nice crew. Very smooth flight."

Pros: "They had the AC on while we were waiting on the plane at the gate for 1.5hours"
Cons: "That the flight was delayed for 2 hours, information was inaccurate/missing, they knew we'd miss our connections but did nothing except, "they'll deal with it in San Francisco" and when we landed there was no one in sight to help us--no escorts/expedite to gates, no one to tell us where to get rebooked, and after going back and forth between terminals, waited in line an hour to get rebooked on a series of flights that would get me in 22hrs later after my original flight."

Pros: "Comfortable"
Cons: "I was in 10C a So I was able to hear a disgruntled AA employee. Just like office politics. But up in the air. I didn’t need to hear"

Cons: "salt free option for snacks; flight could have not been delayed but that’s not the flight crew’s fault. winds at sfo caused us to delay our takeoff"

Pros: "Attentive Flight Attenants"

Cons: "I could not check in online nor selecting a seat in advance. Getting the boarding pass and the seat was a nightmare. British neither American could not help me out. Horrible experience"

Pros: "Nothing. Just the pilot"
Cons: "Everything. Bad communication. 1 h delay. Then 3 hs in the plane. We ran out of gas. 2 more hours taxiing Never seen something similar. I really hope my mileage refund."

Cons: "The terminal 52A-J is a disgrace"

Cons: "The flight was delayed like 4 times!! It was crazy the wait!"

Cons: "This flight is delayed 8/10. Miserable route"

Pros: "Flexibility and helpfulness of staff."
Cons: "I no longer fit in the seats because they keep shrinking the pitch"

Pros: "Awesome roomy seat right behind business class. Could not have asked for better! And it was a gorgeous new aircraft."

Pros: "Nice new seats."
Cons: "The new seats are meant for "people shorter than 6 feet tall" as the flight attendant said to me. Is the airline industry deliberately discriminating against 6'6" people? 15% of the people you seat based on population are over 6'. I'm sick of paying more money for my long legs."

Pros: "Friendly crew"
Cons: "No entertainment."

Pros: "The crew was wonderful! Especially Glenda."
Cons: "The flight was delayed six hours."

Pros: "The flight attendants were great."
Cons: "The flight was over an hour delayed. that meant I arrived home at 1am. That is a very rough morning."

Pros: "The plane was comfortable and flight was smooth."
Cons: "The shuttle to the plane wasn't bad, but would prefer not to have that element included."

Pros: "Everything was timely, courteous & pleasant. The aircraft was very clean."

Cons: "No room, limited entertainment, mediocre food. Was a very uncomfortable, long flight! Luggage late coming off plane, missed connecting flight and was not very helpful in getting rebooked."

Pros: "On time"
Cons: "No leg room, hot plane, airline staff is friendly but clearly bored."

Pros: "Great entertainment system at each seat"

Cons: "Food was nasty and they didn't have a non dairy option"

Pros: "Crew"
Cons: "Before I booked the flight I noticed it was only on time 53% of the time. True to that number we were delayed almost an hour before takeoff. Why schedule fights so close if almost half the time it's delayed? Something needs to change."

Pros: "The crew relax and smile"
Cons: "very small seats"

Pros: "The handed out the customs forms just before landing because they were too busy chatting. I had to fill up the form during landing and got dizzy. During the fligh I asked for water and the stewardess forgot about it."

Pros: "everything ran like clockwork"

Cons: "That fact that on both ways they changed our flights which either we got to the destination late or we had to run across the airport so we don't miss our flights"

Cons: "People still using mobiles as we were taking off. Crew seemed not too bothered."

Pros: "The flight was >1 hour late, which the pilot told us was due to the LAX controllers changing the landing patterns due to weather. So this really wasn't anyone's fault. But there was a large difference in comfort between this flight and the JAL flight from Tokyo. Seats were smaller, and my wife and I couldn't get seats together."

Pros: "we arrived safely"
Cons: "had to take a shuttle to depart from a remote terminal. Had to climb up a long ramp. Seats were very close to each other (no knee room). No food. not enough overhead space for luggage. Very tight and uncomfortable seating."

Pros: "Everyghing was smooth and on time"
Cons: "Nothing at all"

Pros: "I liked that the seats had chargers (even though I didn't need them) and that they offered entertainment."
Cons: "Boarding was over 30 minutes late which ruined my SF plans. The crew was mot welcoming walking on or off the flight. They were also very rude when serving, one even gave me a super nasty look and mumbled something under her breathe because she ran into me. Just a terrible experience. They also didn't tell me baggage prices when I was there just swiped my card."

Pros: "Flight attendants very kind"

Cons: "Flight didn't exist"

Pros: "Once in flight, it was a standard smooth ride to Tokyo."
Cons: "Late announcement of flight delay. Cost me 4 extra hours at LAX, doing nothing. Then, flight delayed again for 30 minutes prior to boarding...and yet AGAIN while on the plane...because of a water shortage. What had the crew been doing in between flights?? Lastly, these delays caused the plane to arrive in Tokyo at 12:30AM (originally it was 10:30PM). All transportations options were closed. I had to take a $90 USD taxi fare into the city. JAL or AA should have given travel vouchers to everyone who needed them. BAD SERVICE, BAD COMMUNICATIONS, BAD RATING."

Pros: "Flight Attendant Sullivan added humor and attentiveness to flight"

Pros: "I got to my destination safely. That's about the only good thing."
Cons: "The flight was delayed 4 times. The airline was not very helpful during times of delay - normally airlines would offer food or drink vouchers - none of that. The flight was delayed for a total of 4 hours. When I arrived into LAX, I had requested if I could go on an earlier flight if there was space (rather than catching the later one - an hour later). They asked me to pay $200 to change it. Fair enough if you want to charge me for a change of ticket - but then the plane that I was supposed to go on got delayed for 3 hours and you don't offer any sort of compensation - thats really not something I expect from American Airlines"

Pros: "I liked that I landed in time to get to my next flight."
Cons: "I didn't like that I had a child kicking my seat back the whole flight and that the in flight movie that I purchased skipped more than it played."

Cons: "Some of the crew were rude, had us waiting forever get off the plane"

Pros: "Service was outstanding, stewardess was funny, plane was very clean. I will switch from Southwest! Good job!"

Pros: "Staff at LAX was helpful and tried helping me get to my next flight by moving me to front of plane at the end of flying."
Cons: "My flight to SFO was delayed so it made me miss my next flight. I ran trying to make it to that gate with a 20 pound backpack on my back, couldn't stop coughing for the rest of the trip after that. American Airlines staff told me that I can pay $75 dollars extra to secure a seat for the next flight 6 hours away. I told them I am not paying anymore because it wasn't my fault I missed this flight. Then, they lost my suitcase so they took 30 minutes to find it. I tried boarding with the priority pass members because my new ticket they gave me was for priority and one of the American Airlines staff members kept getting in my face until I was at the back of the line because I was in boarding group 4. I just never have been treated so poorly before my any airline. I travel often so I will never take American Airlines again. The final straw was another delay at my last layover in PHL, which made me and up traveling for a total of 21 hours."

Pros: "Service, clean aircraft, I felt AA cares about me"
Cons: "Changing gates before boarding"

Cons: "Flight was over two hours delayed, the gate crew did not do a good job announcing the new delay times and reasons for the delays."

Pros: "Nothing"
Cons: "I'll never book AA again."

Pros: "Very helpful people. From the from desk to the in flight crew they answered my questions. Had a weird gate where it's a satellite gate with American Eagle, little confusing but they helped me out."
Cons: "Sat on the runway for like an hour. 100% not their fault, and they kept us in the loop the whole time. Really not a complaint about them. SFO is just always sucked in with fig in the morning."

Cons: "Practically no food was served."

Cons: "Flight cancelled , no communication, the flight the next day delayed two hours and we where given four different gate numbers for the flight, walked backwards and forwards trying to find the correct gate with my children."

Pros: "Pleasant crew on ground and in air. Flight was on time departing and arrived ahead of schedule into SF. Nicely done!"

Cons: "Sitting on tha runway in LA for one hour"

Cons: "Delay"

Cons: "See above"

Cons: "It only takes 1hour from LAx. They fudged the flight time to always show they arrive early.. It's fraud"

Cons: "This was 11PM flight from LAX to SFO which takes about an hour and a half. We sat on the tarmac for nearly two hours with little feedback from the crew and screaming kids (I too wanted to scream). When I requested information, I was told that they had to remove a passenger and get gas. It sounded like a cruel joke. Unprofessional, disrespectful and all around terrible experience."

Cons: "Too much time taxing at the gate."

Pros: "Nothing"
Cons: "There were no Tvs on a 5 hour flight. We had to be put on 3 different flights, and are hours late. United proved the rumors are true!"

Cons: "Not enough leg room"

Pros: "Info for connecting flight."

Pros: "Crew and services."

Pros: "Sat in the back row and they did not get to us to offer soft drinks Every time the attendant made an announcement there was a loud beeping sound that was annoying"
Cons: "No beverage service to those in the back row and all you get is I am sorry. Never flying united again"

Pros: "I liked the fact that American Airlines (which I ended up getting transferred to) pulled through for me and were professional and accommodating."
Cons: "United overall was a complete disaster. They overbooked the flight, so it got delayed until the next day, but not before the involuntarily checked my carry-on due to no more space. When they delayed the flight I asked to get my bag back, but they assured me it would be on the American Airlines flight they transferred me to. Guess what...it wasn't. And now I'm stuck in Portland with nothing but my wallet, keyes and phone, and a small bag of toiletries given to me by American (which should have been United's responsibility). This is the FOURTH trip with United where they have screwed me over with either baggage loss or itinerary issues. NEVER using United after this trip. Next time I book, I'd rather just go with the next price up if it means not flying with them!!"

Cons: "Boarding delayed 2 hours. I did not like that at all."

Cons: "Flight delay"

Pros: "The crew was ok for the type of company they are."
Cons: "The plane was absolutely horrendous. Really uncomfortable. No TV, no outlet to plug in my own device. And garbage wifi."

Cons: "The flight attendants were incredibly rude and you would think that after assaulting a passenger, they'd try to step it up a notch. I had fallen asleep in my seat and I woke up to the flight attendant rattling and waving a snack in my face saying "I don't want to have to come back to your seat if you get hungry later"---the flight was 1 hour, I doubt I would trouble them for much."

Cons: "There was a 6 hour delay"

Pros: "I finally arrived at my destination"
Cons: "he flight was from lax to SFO, the printed ticket said it was a two hour flight whereas I know it is a one hour flight. We proceeded to board the plane on time and then pushed off the gate and sat in the runway for 45 minutes fly to sf and sit there on the runway for 30-45 minutes. Which meant that we were on the runway more than in the air. I would never pick United again for my flight between la and sf as it would be much quicker and easier with southwest, Virgin or JetBlue."

Cons: "We brought wine since we are going on a cruise and had it wrapped safely. Long story short they didn't like that it wasn't used with bubble wrap and charged us 30.00 to wrap the bottles. Nowhere in their site does it say how it needs to be transported."

Pros: "Pretty much on time"

Pros: "Due to predicted snow in Philadelphia united made the flight change easy and I arrived in Philadelphia ahead of the storm"
Cons: "Flight was comfortable and united employees helpful and considerate"

Pros: "Crew was entertaining enough, very friendly, never flying economy again. Economy plus or first class for sure next time"
Cons: "Economy seats were a bit cramped for someone of my height. Definitely liked the economy plus a lot better."

Cons: "Delayed taking off and sitting on tarmac upon arrivalz Flight attendant was rude and pushy."

Pros: "Quick flight, arrived early to each stop"
Cons: "Seats hurt, head rest don't stay up"

Cons: "Marjor delays"

Pros: "Gate and customer service agents were kind."
Cons: "Gate agent and computer decided to give standby seating to terminal traveling customers after a weather delay pushed our original flight past my connecting flights departure. E.g. The airline could have let me make my connection, since other guests, who had no connections to make and were also stand by. In addition, customer service refused to offer a hotel voucher, instead offering a third-party 'wholesale price' coupon to participating hotels. The discounted price is more than the flight! Perhaps United could acknowledge the priority conflict of causing overnight delays and offer a flight voucher..."

Cons: "Flight delayed over 2 hours. Mixed signals from Captain and United whether or not flight would be cancelled. Forced to check only carry on at gate, citing lack of space, but plenty seen when aboard. Entertainment was limited to one channel if you don't want to pay some amount of money. Couldn't even look at the flight status screen. Stuck with only garbage home renovation show."

Pros: "Flight was OK."
Cons: "Flight was about 3 hours late, causing missed connection in SFO and having to spend the night."

Pros: "Economy class had a lot of room."
Cons: "Nothing in particular."

Cons: "Gate got moved 3 times- staff didn't make an effort to inform people. Landed in La and customs was awful- no organization. Someone passed out hit the floor it was 25 minutes before a stretcher arrived. Entire staff did not know how to handle it"

Cons: "So, late, rude flight attendants."

Cons: "Delayed made me late to my next flight which delayed me 7 hours to my destination"

Pros: "Screens."
Cons: "Guy flight attendant didn't even cracking a smile once."

Pros: "Price was nice at $142"

Pros: "Honestly nothing"
Cons: "Both my flights were delayed. The seats are cramped and uncomfortable. They don't give any food at all. There is no free entertainment."

Cons: "the airplane is really old! Don't have any amenities."

Pros: "Not much to go wrong so not much to complain about. On time, smooth, pleasant, ideal!"

Pros: "Will others are not serving food or drinks unless you purchase them, you can count on United fir free drinks."
Cons: "Everything was exellent."

Pros: "Kayak did a perfect job of alerting us via email in a timely manner when changes were made to gates and flight times. I napped the whole flight, so no food or entertainment issues."
Cons: "I forgot to choose specific seats for our return flight. My fault."

Pros: "Nothing was good. Ended having to stay at hotel, changing completely itinerary and car rental, and flights plan."
Cons: "Took us 18 hours to get into Eugene, OR We could have driven in less time"

Pros: "My wife and I are celebrating our 22nd wedding anniversary and we spend 6 hours at LAX. Two of 6 hours where sitting in the plane. This is the first and last time I'm flying with United. I'm extremely disappointed and I'm not looking forward to flying back to California on Sunday."
Cons: "I also hate the KAYAK update. I feel like I was being lie to for those this hours. For my experience I should be refund for my trip to San Francisco. On Facebook my experience is mention to all my wife and I friend, family and co workers. Again, I'm not looking to my flight back home."

Pros: "It's always a mess. SFO should put more chairs on the main level at international boarding and have people sit up there until their boarding class is called. it's simply too tight at the actual gate to have everyone clamorous to get on the plane"
Cons: "Flying in general just sucks unless you're in business class."

Pros: "on time everything was good"
Cons: "the ac was so strong too cold"

Cons: "delay service is really bad cant find my baggages"

Cons: "Flight was canceled and I had to really take matters into my own hands to get a decent replacement flight. Limited automatically rebooked me for 6:30am the following morning, almost 24 hrs out. No vouchers. Lame."

Pros: "I was finally able to change my flight"
Cons: "Bought a ticket on an overbooked flight which was then delayed by 4 hours with no other flights available to switch until the next day causing me to take a cab back and forth from the airport and to wait until he next day to fly which will mean 2 more cab rides."

Pros: "we were stuck during Holliday due to weather at sfo. I think the supervisors name was brent, worked on n getting us back to RDM and booked us new tickets to RDM so they didn't have to close the ER if I didn't make it to work as I am the trauma coordinator at a small isolated hospital with icy roads. I got there on time to get a 7 person car crash and saved them all. He probably saved a few lives just by getting me to work and getting us on a busy week of booked flights. Please tell him thanks to the supervisor that booked for us."

Pros: "No food at all only drinks but in a cup only."

Pros: "The flight crew were very considerate and provided multiple offerings of beverage service."
Cons: "Leg room was inadequate, headrest was not comfortable, armrests were not wide enough to accommodate two people."

Cons: "Cancelled flight the day of flight which ruined Christmas plans never ever again."

Pros: "Staff was very nice."
Cons: "Terrible experience...flight delayed by over 3 hours; no one informed Us of the delay when we checked in to get our boarding passes. Luggages took over an hour to come through the baggage claim carousel... only 4 luggage initially came through the fan belt."

Pros: "cheap"
Cons: "seats do not recline. you have to pay for everything a la cart from food to carry-ons."

Pros: "Bag charged"

Pros: "None"
Cons: "The flight was delayed 5 hours, and we were offered a $100 voucher that would be emailed to us immediately after the flight takes off. I approached the desk to verify with an employee pre-boarding to ensure I will receive this voucher. She was annoyed with me from the start repeatedly saying it will be emailed after takeoff, which was NOT my question. My question was to verify that the email on file was correct. She had a very hard time getting this to her head. However, it has been over a week and I have yet to receive this voucher. Unless, I receive this voucher I will never recommend this airline."

Pros: "More leg room than comparable airlines."
Cons: "Charging for bag in the overhead compartment. Sitting on the tarmac after arriving for 40 minutes while waiting for a gate."

Pros: "An engine went out and the flight was delayed and passengers deplaned. I got to my destination after there were no longer transportation options. No one knew who to send me to for customer service, and they wouldn't offer to help get me home."

Cons: "had to wait around forever until our plane showed up and we were able to board. also i was under the impression that if i paid to check a bag it was a flat fee for my round trip ticket but i had to pay 40$ extra to carry on a bag each way, not worth it"

Pros: "im alive"
Cons: "The customer service. I was lied to twice my agents, wasn't give correct information. My last day was wasted away because I was lied to. Spent hours in the airport because of wrong information given. My back hurts from the seats. Using the website was awful."

Pros: "ORD to/from SFO, both ways the flight was delayed by 4+ hours"

Pros: "Absolutely nothing."
Cons: "Seats have little to no cushioning. Seats don't recline. Checked bag is a gimmick. You cannot check it in if your fight is delayed and the airport checking machines dont operate after certain time. You will have to carry it on and that means loosing all your liquids."

Pros: "The crew."
Cons: "My first flight was canceled without notice, it was a 1:30AM flight. Had to sleep in the check in area of the airport until we could get our next overpriced tickets that will not be taken care of by their 3 options they give you. This shouldn't have been placed as the cheapest tickets available with out big red warnings that it is only cheap if you have no bags. $40 more would have given me free check in bags and a far better in flight experience on another airline. Spread the word to never fly Frontier."

Pros: "On mobile safari online checkin doesn't work. Customer service reps on phone incredibly cannot check a passenger in. I almost missed flight for this. Most uncomfortable seats I've ever had to sit it for four straight hours. Arm rests are hard plastic, seats don't recline, hard seats too. And it's not cheap despite discomfort"

Pros: "We didn't crash."
Cons: "Frontier has to be the worst airline I've ever flown on. You have to pay for everything "extra". Your ticket doesn't even give you a seat, you have to buy your seat extra, carry on is extra... Etc. might as well charge for using their tray tables while they are at it. I can honestly say I'll never fly with them again."

Cons: "At the time I received this survey, (3 hours after my flight was scheduled to leave) my flight had not even arrived to O'Hare and I had no information about when it would arrive or what caused the delay"

Pros: "What did I like? A safe and smooth flight from San Fran to Chicago and back."
Cons: "The seats are cramped and don't recline. I'm an average weight and height and normally don't have such a hard time resting despite long flights, but both flights were uncomfortable. In addition, the flight from Chicago to San Francisco was HOT and no drinks are offered without payment - everything on Frontier is extra $$$ - a bit of a turn off. I'm an avid Southwest customer and I think I will be going back to them even if the flight 'seems' cheaper when searching Kayak. I appeciate you asking about my experience. I love Kayak, but won't be flying Frontier again. I'd rather spend up to $200 more for Southwest to get: comfy seats, free bags, cabin temperature comfort, on time flights, drinks and snacks. It's worth it."

Cons: "The price was good, before you realized the price was a lie and they scam you by charging $45 to carry on or $40 to check a bag! That meant the overhead space was unused and they were just charging more just to be inconvenient. The plane was stripped barebones. The crew were rude, did not smile, and gave me attitude for hitting my elbow with the drink cart. They charge for even getting a soft drink. Nothing about the experience said "we're serving you." It's worse flying a more expensive airline because the rediculous bag fees make it just as expensive and even things that should be free like pleasant staff were lacking."

Pros: "Nothing, I will never use Frontier again. They are just RUDE to the customers."
Cons: "Charged $60 at last minute to bring a small personal bag."

Cons: "Y'all chargin' for juice now? And askin for gratuities on them drinks too? Cmon!!!"

Pros: "Nothing"
Cons: "Unprofessional Service, No In-flight Amenities, Deceptive Pricing (added/hidden fees), Uncomfortable Seating, Miserable Experience Overall"

Pros: "Staff is enthusiastic"
Cons: "Seats don't recline. Minimal padding"

Cons: "Small seats, not even a carry on bag. Crew was not very enthusiastic or rather friendly but you get what you pay for."

Pros: "There was nothing that I liked about flying with Frontier. It is a nothing special airline."
Cons: "I dislike the hidden charges everywhere along the way. They position it as tailored to customer needs but I see as hidden charges. I am surprised that they don't charge for using the restrooms on the plane. When all said and done, it is not a cheap air fare. The customer service was not empowered to help customers. The flight crew was practically unnoticeable. Not even sure what the crew did. It simply is nothing positive that I can say about Frontier. I will even go further to say that if I see Frontier on Kayak, I will not even use Kayak again."

Cons: "everything"

Cons: "Missed my BART train by being forced to wait on the tarmack outside the gate."

Pros: "Initially price on round-trip fare, but price quickly goes up as soon as you arrive at the airport and have to start paying $45 for a small carry on. Crazy--nothing good to say"
Cons: "The price on round-trip fare includes nothing -- I had to pay $45 for a carry-on! Ridiculous!!! 2.99 for water. . . I'm surprise I could pee for free Seats are terrible/tight, uncomfortable, cheap, and overall the worst w exception of Spirit Sloppy uninspired customer support at ticket counter, although flight crew was okay."

Pros: "nothing"

Cons: "had to wait on the tarmac while the flight before us departed. But we were allowed to get up while we waited so that was good. Frontier's website is very difficult to navigate and use. The folks at SFO said that boarding passes printed from Frontier's website are difficult for the scanners at the airport to read -- so I did not get to take advantage of TSA Precheck, which was annoying."

Pros: "Little."
Cons: "Worst flight of my entire life."

Pros: "Took off on time reached before schedule, price was unbelievable ,very comfortable all great."

Cons: "Worst seats in any plane I have EVER been on (and I travel ALL the time). Those steel seats with 0 cushion have resulted in me having the worst back pain and being on bed rest for the past 3 days on severe pain medication with no signs of improvement. I will never fly Frontier again."

Cons: "The web site is deceiving in that it makes you think every seat is an upgrade and no regular seats remain. A distinct "no upgrade" choice needs to be present for people to see. It makes one think, how much money Frontier has made from people due to their purposeful website's lack of clarity. This is pretty pathetic."

Cons: "It was embarrassing not being able to pay cash. The seats don't recline and it is a shame that we have to pay for carry on. We also pay for small snacks. It feels like a nickle and dime experience."

Pros: "Courteous crew."
Cons: "Gate change at last minute. Had to wait for plane to get to gate. 1 hour late. Another 45 minutes waiting for de-iceing but that not their fault. Will not use this airline again."

Pros: "Price"
Cons: "Nothing included, not even water"

Cons: "The Chicago airport was terrible both times. Things not clearly marked. Staff not friendly or available. Long term parking very hard to find and pricing very unclear. Didn't realize we would have to pay additional for just a seat and carry on luggage"

Cons: "Having to pay for a carry on. Having to pay for water on the plane!! That's insane! The fact that it's 2016 and there's no entertainment or free wifi. Ridiculous. I fly frontier out of desperation but never as a choice."

Pros: "Overall great experience. The entire staff was personable and it was a spurt smooth landing!"

Pros: "Crew was friendly and helpful."
Cons: "the seats are uncomfortable. ypu are basically sitting at a 90 degree angle... i also thought it was ridiculous that you pay for a seat instead of it being included in the ticket. Furthermore, the more expensive seats have trivial and funny "benefits" for nearly 30 dollars more, they claim you have more leg room. (no you dont) also say that you can reclein in the seat (not even the slightest bit) and say you are first to receive service (big whoop). i cannot comment on "food" or "entertainment" because there wasnt any. Probably wont book with frontier again."

Pros: "I was impressed with the pilot. Had a very smooth flight. Was one of the best I have had flying."
Cons: "I had a window seat and was very cold. Crew did not go out of there way to make you feel like they cared. A "hello" and "goodbye" was the most we received. The seats could be more comfortable and roomy. Also, when we we arrived the jet bridge did not hook up properly and not one of the crew said to be careful when leaving. It was a good thing I payed attention because it was at least a 3-4 inch drop."

Pros: "Hour delay for flight with no explanation why"

Pros: "Price"
Cons: "Very rude staff. The staff on the plane were ok but the staff at the ticket counter were very rude. I also had a similar experience when I flew to Vegas. I don't care how cheap the prices are, frontier needs to get there act together. There are a lot of other companies to fly with."

Pros: "Frontier staff in SFO (San Francisco) friendlier to passengers than ORD (Chicago). Kept luggage at SFO for pickup when I arrived"
Cons: "Missed flight by 10 mins. Was able to check-in 1-hr before a domestic flight and get my boarding pass printed. However, the attendants were not interested in expediting me, and 4 other passengers going on the same flight, through security. Ultimately, 5 passengers with boarding passed missed their flight even though we had arrived to the airport and checked-in at an appropriate time! After the plane left, an attendant assisted a passenger to rebook their flight, but then left to go on break and left 3 of us stranded. Very few Frontier attendants available to help us. Had to pay $225 for another same day flight to SFO using American Airlines. Learning points: - hard deadline, need to be at gate 10 mins before departure time - lofty and esoteric reimbursement process - Frontier does not participate in TSA Pre-Check, so arrive 2 hours ahead of departure time for domestic flights - Frontier does not participate in other airline organizations, so unless you rebook with Frontier you are paying full price for the new ticket"

Pros: "free water"
Cons: "the flight was late coming and going by over an hour."

Pros: "Nothing"
Cons: "Everything. Frontier is awful and I will never fly with them again. They cancelled the flight for "weather" more than 12 hours in advance. By the time the flight was supposed to leave, flights were taking off from O'Hare without any problem. Next, they could not have been less cooperative in helping my find an alternative route to San Fran. After more than 2 hours of arguing with Frontier personnel, they magically found a way for me to get there via Denver. Finally, once I boarded the flight to Denver, the crew could not have been any less competent. I saw at least two instances where they had given away the seat of someone who had checked into the flight, then had to scramble to find them a new seat. Frontier is the worst."

Pros: "The boarding process was easy enough."
Cons: "The crew was absolutely clueless. Half way through the flight no less than 6 sleeping passengers were woken and shuffled about because they discovered two other passengers had seated themselves in the priority area. I understand the desire to ensure passengers are seated properly. However, it was ludicrous to wake 6 people who were not at fault for this error on their part. They should have been more vigilant at the start, or left the rest of us alone after the fact. Terrible understanding of customer service. Also, our flight arrived early, however, they didn't have the appropriate gate available. Poor planning as we knew we'd be early about half way through the flight. Would not fly again, not because of the disorganized gate business, however, there's a real lack of customer focus on this airline."

Cons: "The onward flight was cancelled and I wasn't provided an immediate alternative flight. On cancelling my entire itinerary, I was charged a cancellation fee and not provided a refund. I would never fly from frontier again."

Cons: "all the additional fees, cancels out any savings on fare"

Pros: "Pay extra for another airlines. Frontier is uncomfortable and you have to pay for everything after the ticket. You only end up saving minimal amounts."

Cons: "Frontier delayed our flight due to a mechanical problem for over twelve hours. Communication was so bad that we could not leave the airport or even the gate because it seemed like we could be leaving at any moment. It got delayed, and delayed and delayed until all the other flights to SFO had left and there was no other option but to pray we got home. Frontier handled the whole situation extremely poorly. I was exhausted and beside myself with frustration. I will never fly Frontier again."
