Pros: "Promptness."
Cons: "Only beverages. Perhaps a little something, like nuts"

Cons: "When two tickets are purchased together I expected seats to be assigned together as well. Apparently this doesn’t happen when booking through a third party site. My husband and I were assigned seats late and in different rows."

Cons: "No comfort given to passengers despite 2.5 hr delay in leaving and another 1 hr on the ground after landing"

Pros: "Crew was very nice"
Cons: "Flight was over booked by about 15 people. Barely got a seat, and it was the middle seat in the very back of the plane. I bought the ticket and picked a seat...it shouldn’t be that hard to be able to board the plane and get a seat. Will likely not fly with them again. Don’t want to risk not being able to get home when I need to."

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

Pros: "All good"

Pros: "I had heard about limited food options during covid flights but everything was tasty and generous. I always appreciate it when my initial flight books my check-in to my final stop and gives me all my boarding passes at once and Delta did just that. They were also really good at communicating updates like changes to the gate."
Cons: "People should just be prepared to be asked more questions than usual. It can definitely make you feel nervous but just remember that the new covid restrictions are stressful for flight staff just as much as they are stressful for you. Be cooperative and honest and you shouldn't have any problems."

Pros: "I would like to have ore of a grace period to check baggage."

Pros: "The service was amazing , the staff was honestly friendly and nice"

Cons: "See above"

Cons: "Got in early"

Pros: "Great service, nice agent friendly"

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."

Cons: "Force me to take a bad seat"

Cons: "Layover"

Pros: "The temp"
Cons: "It was too hot."

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

Pros: "The boarding was efficient"
Cons: "Three hour departure delay. No explanation given. No apology."

Pros: "I love Delta. Smooth boarding. Quality service. Keep it up!"

Pros: "The Crew was amazing The seat was not comfortable at all Had a broken back rest"
Cons: "Fix the seat Broken back rest aren’t comfortable"

Pros: "Before boarding, which was late, the crew called me to the podium twice to ask me to give up my aisle seat which I had pre-booked, each time losing me my seat in the crowded waiting area. The flight arrived in SFO two hours late."
Cons: "The flight could have been on time and the boarding crew could have been considerate."

Pros: "The crew serving the plane didn't look like they wanted to be there. Somewhat abrasive. The entertainment was poor and not very easy to access through your mobile, Iphone and Ipad. If you want to provide a better customer experience, equip all your planes with seats video screens. Passengers on a 4 to 5 hours flight don't want to have to figure out what do to watch a movie or TV. I don't fly American that often, but wanted to give it a try to see the difference between you and the other airlines. I have to say that on the return segment (ORD to SFO), I was not that impressed."
Cons: "See above"

Pros: "The crew was fantastic and everything about the flight made it feel like how flying is meant to feel!"
Cons: "With a long flight seat space is always a concern, I was fortunate to have an empty seat next to me so I was comfortable, if had someone next to me I know that comfort level would have dropped considerably."

Pros: "Crew were very helpful"
Cons: "I have an injury so I paid extra for 'extra leg room" but there's a wall between economy and business class so very little legroom. My leg was hurting a lot and the flight attendants had to find me a different seat because I could not stay there for 5 hours. I wouldn't have paid extra for this seat."

Pros: "The crew was amazing but I was on a United flight since American was late leaving Athens. AA booked me on a later flight from Chicago to San Francisco on United. They issued separate inside seats for my wife and I. United showed me their kindness by putting us together in economy Plus."
Cons: "I don't blame American for being late but putting me on a United flight and splitting up my wife and I seperate seats was a little under the bar."

Pros: "On time. Fast boarding. Comfortable seating."

Cons: "almost an hour late - and no explanation. First class was about equal to Jet Blue regular class but without seat power."

Pros: "The seats were decent for a domestic flight. Everything was timely."
Cons: "More food. Better entertainment."

Cons: "if the crew/flight wasn’t filled with racist tendencies that forced a black man and his partner to take a new flight because his “tone” wasn’t to their liking when he responded to accidentally being the wrong seat, costing us 90 minutes at least of delays because they deplaned us all when all."

Pros: "Flight attendants were friendly and thoughtful."
Cons: "Seating is too tight. Hard to believe that in 2019, major airlines still have seats without any electrical or UBS outlets for charging devices."

Pros: "Everyone was nice and it went smoothly!"

Pros: "Everyone was so nice and I appreciated the chance to pre-board with my toddler! Thank you."

Cons: "Delays, seats are cramped and uncomfortable"

Cons: "Never made it to Chicago, rerouted through Washington DC."

Cons: "The flight was delayed. The food was not great. There is not a lot of space in these planes, and it was a long flight. There is no power supply."

Pros: "Crew was very nice Flight was very comfortable"
Cons: "Mediocre snack/meal"

Cons: "Lateness, seat comfort and gate checking a duffel bag"

Cons: "headphone jack defective but more importantly the SFO arrival gate not available for over 45 minutes...."

Pros: "Quiet flight"
Cons: "Very old plane with zero on board entertainment. Seats in front of exit row barely recline."

Pros: "When the lettuce looks like the salad you forgot to put away last night you know it has been around and about too long! Pity!"

Pros: "Everything went very smoothly and the entertainment was quite good. New movies, international films, and games kept me happy from boarding to landing."
Cons: "Nothing to complain about really. I thought that the flight attendants did a great job."

Pros: "Flight was on time."

Pros: "The row I was in was spacious, I'm glad that I paid extra to move closer to front of plane and then paid extra to get an earlier boarding. I would recommend seat 13C for these types of flights. Legroom was good and I was comfortable."
Cons: "The entertainment program was a bit glitchy towards the end of my flight, but I slept inside. Maybe check all screens and such because it wasn't really registering when I would push the buttons."

Pros: "See above"
Cons: "See above"

Cons: "Surprisingly, AA provided the worst experience of the overall itinerary, compared to Aer Lingus and Iberia. The AA plane was outdated, cramped legroom - despite having purchased an "upgraded seat" and departed 1hr late"

Cons: "Lovely flight, but onboarding groups were a nightmare. Given the chaos, they started forcing bags to be checked early."

Pros: "Good communication"
Cons: "I don't understand why you boarded the flight when it seemed you knew there would be a delay to take off to SFO. We boarded only to learn we would sit at the gate for 30 min and the wait on the tarmac for anothe 40. Why not just delay the flight an board an hour later? It would have been a lot more comfortable in the terminal."

Pros: "The snacks are good and the seats are fairly comfortable. The entertainment options were nice too."
Cons: "But paying $8 for 30 mins of Wi-Fi is just outrageous. I did not, and will not ever pay that much for internet service. Additionally, my bag was asked to be checked at the gate. Mind you, my bag was a Airline Compliant design, that fit into the overhead bin sideways on the same sized plane going out to Chicago. If the flight were full, I would understand them being cautious about space, but the plane was barely over half full. It was just an annoying inconvenience."

Pros: "IFE"
Cons: "Delay 1st leg. Had to rebook to later flight. Later flight delayed. Then delayed again due to crew time out. Arrived 4 hours later than originally scheduled. Meaning public transportation could not be used to get into downtown final destination. Made an originally short trip even shorter."

Pros: "Routine flight. No issues on time departure and arrival"
Cons: "Paid extra for exit row seats, felt they were not worth the extra money. The extra legroom was great but the armrest did it move and I felt like I was sitting in a box."

Pros: "The crew was able to seat my husband and I together at the last minute as my husband has mobility issures"
Cons: "The crew seemed like they could care less about the passengers. Choice of either one snack bag of pretzels or a biscotti ~ very minimal. No headphones were offered for the movies."

Pros: "tv!"
Cons: "babies crying"

Pros: "Clean environment of the terminals and the speed of the shuttle."
Cons: "no comment."

Pros: "It took off on time and life was good."

Pros: "Great service!"

Pros: "Everything"

Cons: "Same as previous response."

Cons: "As I mentioned in my last comment I was seated at the back of the plane on over four and a half hour flight by the time the food got to me they had ran out that I mention that I'm a diabetic with high blood pressure so I have to sit and suffer for over 3 hours will never ever fly American again"

Cons: "The plane was freezing and made me very uncomfortable! I asked the flight attendant for a blanket and she told me no. Even though I saw some in first class.... I would have purchased one. It was very hard for me to fall asleep because of how cold I was. Comfort is one of the main things I expect in a 4 plus hour flight."

Cons: "Due to the delay which caused us to miss our connection we had to get a hotel, which we had to pay for. It also caused me to miss work the following day."

Pros: "Everything was pretty decent.. Best part was the price.. Boarding was good staff was good"
Cons: "Wasn't enough room.. kind of tight.. Couple more inches all around would have been perfect though"

Pros: "Ease of travel"

Pros: "All personnel where polite,helpful, and respectful. Greg to have wifi and power chargers."
Cons: "There was no real entertainment on the screens. No movies."

Pros: "very good no problems.."
Cons: "all good thanks much"

Cons: "Having missed my scheduled flight, when I got on the later flight, we waited an hour on the tarmac to takeoff and 40 minutes on the tarmac in San Francisco for a gate. Basically three hours of sitting on a tarmac all day because gates weren't available. How can that possibly be? Do you not know the plane is coming? Terrible."

Cons: "We wait to long for the connection"

Pros: "Rough landing"

Pros: "Everyone was friendly and helpful"

Pros: "FINALLY American has up to date aircraft!!! Five years ago half the seatbacks and lighting on long distance flights didn't work. Swore I would never fly them again. They have redeemed themselves. nice aircraft"
Cons: "Inflight movie questionable. Couldn't figure out wifi entertainment options from inflight magazine ( over 60) and staff too busy to assist ( though didn't ask - just could see they had their hands full with beverage service). Would recommend video instructions after preflight safety video for tech unsavvy travelers. Also reminder on reservation to bring your own headsets and electronic devices."

Pros: "Free upgrade to business class"
Cons: "Nothing"

Pros: "Yes"
Cons: "Yes"

Cons: "United Airlines in our experience runs late putting a lot of pressure on any ongoing connections . Not clean . Staff not friendly . Only sometimes helpful."

Cons: "Boarding/unloading"

Cons: "If they had veggie options or any options for food when they arrived to my seat"

Cons: "The boarding process. Passengers having to get out to let another in... I know this is nothing new, but there needs to be a btter w"

Pros: "No food"
Cons: "No food"

Pros: "Crew, and boarding was good and most of the flights were on time so thats part of the trip was pretty good"
Cons: "The good was crappy, definitely not comfortable at all for such long trips"

Pros: "Great service from check in to landing"
Cons: "None that I can think of"

Pros: "The passengers next to me we're good."
Cons: "The fact that they only let you watch content on your device despite having a big screen in the headrest for DirecTV that was pay-only was not putting those screens to full use. Aso, why down 4-hour flight not get a meal, but only one tiny bag of pretzels?"

Pros: "crew members on board"
Cons: "Delay after delay. Very unpleasant experience with United. No accommodations or attempts to do so."

Cons: "I was at the wrong gate forgot to check the board. Almost missed the plane."

Cons: "Very uncomfortable plane!"

Cons: "We had to go from DC to ORD then back to GEG. It was out of the way and took much longer than expected. Other than that all went well."

Cons: "We got moved to a bulkhead seat with no storage - this was after selecting my preferred seat and paying extra. We almost were moved out of economy plus but I noticed that the seat assignment had changed."

Cons: "Entertainment system Movie Streaming erratic"

Cons: "1 hour delay at the gate in the plane before we left Chicago, then when we arrived in San Francisco 1 hour on the tarmac waiting for our gate to open.."

Cons: "Delayed way to long!"

Cons: "Crew was not great. They make me to wait so long to get drink. They are busy selling their food and crew was worried about how much they sold. It sounds like store business. Do not care for what other people looking for. Very poor crew service and they roudhg too. The"

Pros: "Flight was on time"
Cons: "The whole flight seemed like a sales pitch. Pay to upgrade to our empty seats with a little more legroom. Pay to watch TV cross country (Delta, American, and all others are included). They did have more sales pitches on the screen for 6 hours though. Pay for snacks. Not even peanuts or pretzels anymore. They do give you a disgusting wafer. Flew back on Delta and didn't see any of this. Between this and their recent beating up of customers, no more United for me."

Cons: "It was an almost 5 hour flight and all we were offered was a small bag of pretzels."

Cons: "OVER CHARGED ON MY ACCOUNT"

Pros: "All went seamlessly. Except for WiFi not working. Thank goodness for books!"
Cons: "No WiFi"

Pros: "We landed safely"
Cons: "20-30 minutes on the tarmac to take off. 30 minute wait after we arrived at the gate to have United staff attempt to line up the jetway with the cabin door. United is really firing on all cylinders lately"

Pros: "Not much."
Cons: "Originally, there was an announcement that we would be delayed by 45 minutes because of "air traffic" issues in San Francisco, where we were landing. In spite of this, the captain decided to have passengers board the plane, and try to push our way up the line, so to speak. Well, once we were on the tarmac, the flight crew were told that the plane could not take off, and that we needed to wait there for 45 minutes, without moving, in our seats, with nothing to do. Even though it would still not have been ideal to wait 45 minutes at the gate, at least we could have walked around and could have entertained ourselves."

Cons: "Pilot missed the landing. Staff uncourteous."

Cons: "Customer service"

Pros: "Nothing"
Cons: "Everything"

Cons: "The delays"

Pros: "Very helpful desk attendant when flight was delayed to help me get later connecting flight. While flying and waiting on runway we received free direct tv which I really appreciated"

Cons: "How I was notified last minute and had to figure out"

Cons: "missing USB charger had to "burn fuel" prior to take-off not enougb space for carry-on"

Cons: "Didn't ride. Stuck in Chicago overnight."

Pros: "The wifi worked impressively well. However, the selection wasn't extensive. The crew did the best they could even though the plane was three hours late."
Cons: "The gate area forces passengers to line up in the walkway disrupting walking traffic in an already crowded Chicago airport."

Pros: "Quick boarding, comfortable seats, leg room"
Cons: "Had to ask more than twice for a refill before attendant remembered, and there was no space overhead for my bag so it had to be checked."

Pros: "- Flight arrived on-time - Well appointed terminals in ORD and SFO - Good cabin crew"
Cons: "- Economy seats are too small (I'm average sized). - United flights that are close to full never seem to have enough room for carry on luggage. This was no exception. As a result, people line up 45 minutes before the flight in order to get on first so they can claim overhead bin space. There should be a better way to manage this."

Cons: "Original flight cancelled, rescheduled onto flight that was delayed & wouldn't make connection, given standby on a flight and didn't get it. Now have to stay the night in Chicago, and tell my boss and my son that I won't be there tomorrow. Spent an hour crying in the airport. No compassion from airline staff."

Pros: "I didn't die."
Cons: "UA1742 plane (777) is a poorly designed piece of junk. The call button for the flight attendants sits right where everyone's elbow rests, and as a result the flight was 4 hours of constant dinging despite 3-4 announcements of the problem. it is unbelievable that this seat was designed in this matter. Incredibly poor engineering."

Pros: "On time flights"

Pros: "I was able to watch Monday Night Football on Directv."

Pros: "Couldn't have gone any smoother I would do it again tmrw."

Cons: "One flight was cancelled resulting in a 6 hour wait, the second flight was 2 hours late. Meat meals ran out quick resulting in a vegetarian only option for a lot of passengers"

Pros: "I got a really good deal on the flight so I'm happy with my experience given the amount of money I saved. The crew is very professional and the flight was uneventful (a good thing)."
Cons: "I always wish flights could be more comfortable, especially when they are over 3 hours long. However, since I am unable to pay for the upgraded seats I realize this is a problem I will continue to have."

Pros: "They got us on their plane."
Cons: "Arrived in Sam Fransico 1 1/2 hrs lay. Middle of rush he!"

Cons: "Good"

Pros: "I like the friendly service and the promt service"
Cons: "Dea randomly stopped me and said they was checking for narcotics. Nothing big but was a weird inconvenience"

Cons: "Poor seat selection options."

Cons: "Tv was subpar"

Pros: "Seat was roomier than I expected for economy class. United did arrange for hotel, shuttle and food vouchers for those of us who missed our connections. The hotel (Biltmore in Santa Clara) was very nice. The plane crew did their best to help passengers with connections to catch, especially those with international ones."
Cons: "Delay at boarding: long LONG motionless line with no explanation to this large crowd of passengers led to delay in departure. Many missed connections, including mine. Later on, learned that some mechanical problem was the cause, so delay understandable, but someone should have made an announcement to the waiting passengers. Due to conventions in SF, we were told, we had to be put up in Santa Clara, down in Silicon Valley, an hour away. Expecting major morning traffic jams, we asked for a 5 am shuttle (plane leaving at 8, plus having to go thru security again). Since it took 2 hours from landing in SF at 10:30 pm to getting to the hotel, there was little time for sleep and no food available at the hotel at those hours. The shuttle drivers seemed confused, relying on GPS to guide them and speaking little English."

Cons: "You are required to pay to watch the tv. It's free with Delta."

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

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

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: "The upgraded seats were spacious and the price was low"
Cons: "Our flight was delayed four hours because of a maintenance issue, which happens, but the staff was so uncommunicative. They knew the flight was delayed for 30-mins before they made an announcement. I asked the staff if they planned to let everyone know and she actually said "I don't want to get too many questions". The other reasons I probably wouldn't fly with them again: - Excessive fees for carry on bags - No entertainment at all - No wifi"

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."

Cons: "Had to pay extra for carry on! Which they checked anyway. No wi-fi or tv options. Basic drinks and crackers were up charged. Delays and slow baggage claim process. Overall savings on fare not worth the hassle or deceptive price practices. Will never fly with Frontier again."

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

Pros: "Crew is nice, none of this is their fault"
Cons: "Delayed flights, added on fees, confusing customer service experience, horrible seats, not worth the "cheap" price, it amounts to the same as another airline but with an overall way worse experience."

Cons: "Waiting for luggage for at least 2 hrs. Receive different answer every tin you callreagarding charges. Will never use them again"

Pros: "Attention of the fly attender was very good"
Cons: "My fly was delayed for almost 6 hrs in I don't recive any information about that no email no txt message"

Pros: "Friendly staff. Can't beat price of ticket. Direct flight."
Cons: "Baggage policy is too restrictive."

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."

Pros: "Your flight's delay was unchanged; I likes its consistency."
Cons: "I did not like paying $5 more for my checked bag. Although I did log in to see if I could check in more than 24 hours before the flight nothing suggested that I should pay for my bag though I could not do seat assignment at that time. I did not like that I paid $5 for set assignments inferior to what my friends got by taking their chances. Although I understand your motives, not showing what the free alternative is seems a bit smarmy. The one hour delay on the tarmac before we could get to a departure gate was not directly your fault, but it was annoying."

Cons: "Old flight and I won't flight with em"

Pros: "Everything was smooth and on time."
Cons: "Small, uncomfortable seat. Pay for everything, even a soft drink. I thought the check in, where they try to sell you a seat assignment when you don't have to pay, is almost criminal. Very sleazy..."

Cons: "Extremely uncomfortable"

Pros: "The plane ride itself was very nice. Smooth ride and friendly staff."
Cons: "We got to the airport early and had to sit on the tarmac for 45 minutes. Once we finally got off the plane, we had to wait for luggage for another 30 minutes."

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"

Pros: "Very informative on where to go!"
Cons: "Not very informational on security policy"

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: "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: "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."
