The checking crew was rude Refusing to help us

My flight never left because there was no pilot my experience was awful and I lost money

Very delayed due to maintenance servicing and flights not arriving on time. Crazy how many hours we were stuck wearing a mask. Just terrible and unethical.

I never took this flight thanks to my disorientation from being on lockdown for 5 days, and 3 trips to a clinic for PCR tests. I simply confused Monday with Tuesday.

Love the experience, a little bummed about the AA flights. Its great to have more flexibility with times, but its not the same customer experience. (Mix of snacks, entertainment, free wifi. It seems more of a benefit in terms of experience for AA customers now flying JetBlue that the other way around

Cons: "When my flight with American Airlines cancelled, I felt so panicked because I needed to be in Florida on Saturday night. But thankfully, lady who works for American Airlines solved my problem on the phone in couple of minutes easily. After that, when we were boarding to the aircraft, there was a cabin attendant lady. She came to us and ask me and my mother if we can talk English.I answered her with yes we can, but she demands to talk with my mother. And English is not her native language, but it doesn't prove that she doesn't know it. She tried to ask questions to her like, "where were you today?" so we couldn't really understand the reason for her to ask those questions in the first place. So we couldn't really say anything. While we were talking about my mother's English, the all aircraft was watching us, and trying to figure out what was going on. After all, she made us to sit there and wait her to replace us with other passengers. We waited the whole aircraft to be seated, then she took us to another seat with my mother. I can understand that it is her job but I'm not sure, if it had to be that much discomfort. We got pretty upset about it and it affects our flight quality. Plus, while cabin crew serving beverages, they didn't really ask us anything. We needed to call them for our order. To be honest, I would never flight with Delta. It was a disappointment."

Cons: "On the way to Denver from Miami we were on a nice new AA plane with TV entertainment, movies, power, and comfortable seats. On the way from Denver to Miami we were on an old plane with no entertainment and old uncomfortable seats. If this is going to be the case, charge me less up front as well. My daughter had a terrible time for a 4 hour flight."
Cons: "LATAM is an absolutely horrible airline with horrible customer service. They changed the itinerary more than 3 times. I contacted KAYAK to help and you (KAYAK) did not help stating "that is the Airline's fault". This may be true. But if you are going to take my money for the tickets, please also take the time to address my concerns and solve the problems created by the company that you work with."
Pros: "Nice and clean and seats were comfy"
Cons: "No outlet to charge devices"
Cons: "Delays, not helpful staff, not even a meal for a 5+ hr flight. No headphones available. All of this after American Airlines delayed flights and caused us to miss connecting. A whole night delay with no luggage because not one American Airlines staff could step up and help us. It was easier for them to be lazy and say “I know how you feel”. Never Again American Airlines"
Cons: "No TV nor entertainment of any type. Food choice terrible. I am allergic to shellfish and the other option was pasta which I don’t eat. Had to feed on two cups of nuts... really mediocre."
Pros: "The onboard entertainment has definitely improved. Nice to see how organize is the boarding process when compare to other local airlines."
Cons: "I was seating in the front of the plane were the seating should be better. The seat reclined minimum. Also, had the had luck to travel next to an amazing mother who was traveling with two small kinds and a dog. Brave woman but nasty flight for me. Need to improve the meals on the international flights. Too mediocre."
Pros: "Finally taking off"
Cons: "Being stuck on the runway"
Pros: "Their service is useless. Processes are in need of a major overhaul. They have become too big for themselves and have not adopted the customer-centric value that prevailing companies have incorporated and are implementing. I predict that they will not be around in the next 10 years if changes are not made."
Cons: "Kayak should be more particular who they partner up with as being more selective will bring more value to your brand."
Pros: "Nothing"

We got boarding group one but by the time all the families with kids, first class, and frequent flyers went ahead of us they called all remaining groups together. Forget about overhead space left over, we had to gate check carry on. Seats were very uncomfortable, no room under the seat because of a big metal box for power outlets. No leg room, sat shoulders and thighs touching with neighbors. No meal service, just drinks and pretzels, luckily we picked up something to go changing planes in Dallas. Never again!"

Pros: "Nothing"
Cons: "First of all, we got on plane on time but had to wait 1h and 15 min to take off!!!ok that's the airport!!!They didn't even welcome us in plane.No food at all!Coke in plastic cup?Just this?No smile, not a blanket even air condition so strong!!!The manager of American Airlines should try to fly with Greek companies!And I don't mean with Olympic airways in Onassis time(with Coco Chanel suits the hall crew) but I mean now, in poor Greece's Aegean air which again and again wins the price of best airliner in Europe..Service, crew, foooood!!!Polite people..Blankets!!!

Cons: "Flight got delayed and almost missed my connection."
Pros: "The fact that I got fully refunded, even though I still lost out on $500+."
Cons: "My flight was supposed to leave at 12, and all that Kept happening was me receiving text messages about delays pushing my departure time back to 5:35pm. I missed a big birthday event I was throwing for my class that I teach, lost out on money spent for the event and missed out on all the memories made that night. I never got to leave, ended up cancelling my flight. What a waste of time. Seems to always happen when I fly through United."

Cons: "Charge for carry on Middle seat No full can of beverage"
Pros: "Courtesy of crew."
Cons: "Left late. Arrived late. Bumpy flight."
Cons: "Basic Economy tickets are a joke. They are no savings for customers just added restrictions and an overall unenjoyable flight experience as you are being surveillanced by every United associate to ensure you pay for a carry on bag. United and Spirit airlines are now one in the same. United hasn’t suddenly introduced lower fares than before, but rather is reducing the benefits that come with the most basic fares."

Cons: "WHEN I TRIED TO SPEAK WITH AGENT SHE GAVE ME A QUITE THE LOOK SHE DIDNT EVEN RESPOND.."
Cons: "What ever happened to leg room? And I know that real food is a thing of the past on airplanes, but at least Jet Blue provides snacks that occupy more than one mouthful"
Pros: "I had 2 awesome flight attendants, Scott and Rico. They were friendly and I talked to them for a bit. I think that they didn't have to help me with what I needed, they just smiled and said yes. I didn't have anyone in the middle seat, so I had plenty of room.

Pros: "It left on time and arrived earlt"
Cons: "I was seated in a window seat and another woman my size about 110 pounds was seated in the aisle however there was a 400+ pound man sitting in a middle seat which made it very difficult for me especially to even sit back because it was touching me the whole time when you have somebody of that size You should make sure they are on and I'll because then the find attendance would have some difficulty getting through instead of your passengers being inconvenienced either that or force people of that size to take two seats"
Pros: "Flight Attendants were nice."
Cons: "The flight was expensive and they wouldn't let us or anyone place carry ons in the over head bin. It was an expensive ticket and didn't include checked bags ($25 more). Carry-ons wound up being "stowed". It would have been nice to know before I bought the tickets that I needed a smaller carry on."
Cons: "I paid good money to be back by 6am however I was delayed and had flights cancelled which made me get home 10 hours later than I should have. This was an overnight flight, so all the places to buy food were closed- United didn't offer snacks or blankets or really anything for the troubles. There were kids also stranded."
Pros: "It was on time And very convenient"

Cons: "I don't like the seats, they have no cushion and they don't recline. Plus the tray table is super small. Also you pay for all drinks. Another thing the pressure is horrible in these planes. It seems they try to cut down on cost so the cabin is not pressurized right to reduced your ears from getting the over pressure from the ascend and descent of the plane."

Pros: "Price Comfort You can pack a backpack for a short trip and not pay baggage fees. Haven't had a delay in a long while. No cancelled flights since flying with them Boarding is typically fast and we typically arrive 15-30min early"
Cons: "Crew is hit or miss Price of onboard snacks is ridiculous"
Pros: "Nothing"
Cons: "No consideration for customers"
Pros: "I liked that there were no issues with my flight I was able to just board , get there and have no problems"
Cons: "I don’t like the fees for everything. It kinda just made me annoyed that there were fees attached to everything that doubled the cost of my flight."
Pros: "They charge you for everything nothing is complimentary . The seats are super uncomfortable. No tvs can't recline. They want you to think your saving So much because the ticket is cheap but they end up charging you for literally everything else. They charge you for everything nothing is complimentary .

Cons: "They charge you for everything nothing is complimentary . The seats are super uncomfortable. No tvs can't recline. They want you to think your saving So much because the ticket is cheap but they end up charging you for literally everything else. Not worth it at all!!!"
Pros: "Arrived on time/left on time!"
Pros: "On time take off Price"
Cons: "Seats were so uncomfortable my neck and back hurt I paid to upgrade seats for more room I did no good to have more leg room in a terrible seat"
Pros: "Nothing"
Cons: "They change my flights"
Cons: "Red eye flight so food and entertainment were limited. Comfort was an issue if you were trying to sleep as I was in a middle seat."
Pros: "Service was good."
Cons: "When I booked the flight I did not realize it was bare bones on amenities. Each checked in bag is $30 in advance and each carry on is $30 in advance. If you purchase at the counter.it is way more. Also there is a charge starting at $12/seat for advance seat selection. Then onboard snacks and beverages star at $2.99 each. Next time I will book where the amenities are included in a flat rate."
Pros: "This was my first time flying Frontier, and I was pleasantly surprised with how smoothly everything went! Check in was simple, the flight was on time, the cabin was spacious and we arrived almost an hour ahead of schedule! I will definitely be flying with Frontier again!"
Cons: "I was charged $10 extra to check a bag because I didn't pay in advance. This was my first time flying with Frontier, so I was unaware of this."
Cons: "The flight was delayed 4 hours with never an alert to any passengers. The crew didn't even show up until the flight was already supposed to be boarding. I did not receive any message or alert that the flight was continuing to be delayed. I've never experienced anything like this before. And nothing was done to better the situation."
Cons: "The flight was delayed over 3 hours while we waited for a pilot to show up. There is a charge for everything including water or switching to a vacant seat after take-off. An elderly woman became dehydrated and nearly collapsed during the flight. She was moved to the seat next to me where there was an entire empty row. I spent the last 30 minutes of my flight trying to assist her. I am a medical professional and am certain that she was dehydrated. The seats do not recline."
Pros: "Boarding was a little confusing towards the end I said in zone three Arbor they got the preferred passengers board it then they called 12 and three all at the same time"
Cons: "There was an accident that prevented me from arriving at the airport the recommended 2 hours prior to boarding. Anyway I managed to get there a whole 30 minutes in advance but the people didn't even try to let me get through ..they just said No and that was that."
Cons: "I had to pay 2x$45 for my carry on and there was nothing mentioned when I was buying the tickets. I feel robbed an will not fly again with Frontier and will ask my money back."
Pros: "The flight was on time, and actually arrived about a half hour early. The crew was very attentive. Yeah, you have to pay for everything including carry-on, but if you do your homework then you know what bags you can take without having to pay the fee. If I'm traveling on a budget then I would definitely take Frontier again."
Cons: "The chairs were very uncomfortable making sleeping impossible and sometimes painful, but I can't really expect luxury for a flight that cost me $115."
Pros: "I don't like the policy"
Cons: "They service suck I don't think they should be in business"
Pros: "Friendly staff."
Cons: "Seats very uncomfortable, tight space, knees/legs cramped. Can't believe the additional prices for a seat, like I have the option to stand! So ridiculous!"
Pros: "The flight took off and arrived on time"
Cons: "All members of the staff were rude (baggage, boarding, in flight, corporate on phone reservations). Purchasing tickets was terrible. Frontier's goal is to find anyway to get additional money from you and they stick it to you. In the end, we paid $200 more for this flight than if we had flown Southwest or JetBlue. I understand that budget airlines remove amenities to help control the cost of the flight. However, this experience felt more like buying a used car from a second hand car lot. The staff seemed to delight in finding ways to get more money from you, everything about the experience screamed cheap, and in the end, I paid more in extras than I did for my tickets! Pass this one over if you are looking for a cheap flight."
Pros: "nothing"
Cons: "Paid an extra to get a extra leg room and recliner ($50) when I did the check in... got there yes I had the extra leg space but the seats wasn't reclining the way they advertise... plus no curtain to block the work area from the passengers, a overnight flight with the lights in your face was impossible to sleep."
Pros: "Cheap"
Cons: "Arriving at O'Hare to take this Frontier Flight.. there was a line a mile long for Frontier Airlines. They created a mess and did not try to assist those of us in line. The line was to check in bags. There were 3 different flights, and it was so unorganized. I realized after an hour that I didn't need to be in this line. I had paid for a carry on, thank goodness otherwise I would have missed this flight, like many did behind me. The flight attendants were rude! I needed to purchase a drink to take some medication, and they made me wait. It was ridiculous."
Pros: "Male steward was hilarious"
Cons: "Seats DO NOT RECLINE on a 5 hour flight! $5 for a soda, no in-flight entertainment, $40 for checked in luggage, $44 for carry-on luggage. Nickel & dime you on everything. I'd rather pay a bit more in fare and get what you get on other non-budget airlines. This is scraping the bottom of the barrel."
Pros: "Seats are short on seat padding. I was told that it would recline. . The.crew was great."
Cons: "Add a buck to the bill and give me coke. Don"t need a snack."
Cons: "Mandatory baggage charges are such a ripoff. I could have gone on delta and added miles, thought I was getting a deal. My ticket was $60 extra because of the mandatory carry on fees."
Pros: "The crew was very friendly and helpful. We arrived an hour early . The flight went well. I just enjoyed having staff that were friendly it makes taking Frontier worth it."
Cons: "Worst airline to fly with.. they lie about everything and don't accommodate for any mishaps and discomfort and issues."
Cons: "Very uncomfortable. Also after paying the extras, not sure if it's worth to fly a "cheaper" airline."
Pros: "Smooth transition getting on and off the flight."
Cons: "There was no tv's on the flight and only complimentary thing we got was water."
Cons: "The way people jostle to get off cutting in front of you If the crew would remind people to wait their turn when deplaning it might help"
Cons: "I booked my flight and when I checked in I had to pay an additional $16 to reserve a seat. Once you pay for all the incidentals, I would have come out cheaper to book on AA or Delta and have a much nicer experience. I felt like i was on a Greyhound bus."
Cons: "The return flight has been cancelled and there is very little help on finding an affordable replacement."
Pros: "It felt like time flew by and not a single problem. Left on time, arrived 40min early, and bags were off ASAP. I was asleep for the rest of it, but definitely a smooth one."
Cons: "That the nap was shorter because we arrived 40 minutes early."
Pros: "The base fares are decent and the crew is friendly."
Cons: "The seats are extremely uncomfortable and the airline has taken penny pinching to the extreme and it shows. The baggage fees are way too high."
Pros: "The crew was nice. Not their fault that the seats are uncomfortable and immovable, and that refreshments are not complementary."
Cons: "The airlines company's only concern is to cram as many people as possible into the smallest possible space. Horribly uncomfortable."
Pros: "Everything was excellent"
Cons: "The Frontier flight was a rip-off. I was charged for a seat and for carry-on luggage which should have been included in the advertised price. I will not fly Frontier again."
