Pros: "Excellent crew and clean aircraft"
Cons: "Sat on tarmac for 20 mins because we were early..."
Pros: "The crew was communicative and courteous."
Cons: "There was a flight delay in LAX due to a maintenance issue. The captain and crew informed us before we boarded the plane which was excellent. However, they could not figure out what was wrong with the planed and delayed the boarding for another 3 hours, putting our 1900 departure time to 2100."
Pros: "Nothing"
Cons: "I came from a long trip from France, the seat I was assigned was not reclinable, close to the restroom. I was totally exhausted from the previous flight, not able to sleep at all and when I tried to stretch my legs by sitting sidewards on the aisle a crew member keep bothering me to keep my legs out"
Pros: "Flight cancelled"
Cons: "Flight not cancelled"
Pros: "Very comfortable, no complaints."
Pros: "Nice new seats"
Cons: "Was too warm inside the plane. Boarding address was mobbed and not very well managed"
Pros: "Yes"
Cons: "Took off late. Other than that very comfortable and great experience"
Cons: "THE FLIGHT WAS 5 HOURS LATE"
Pros: "It is a busy travel day and this flight was unbelievably smooth. The entire crew was competent and friendly."
Pros: "Overall service was great."
Cons: "Flight was delayed 5 hours."
Pros: "Having three seats."
Cons: "I had three seats to myself! After getting elbowed all the way from Amsterdam to Minneapolis, I was tired and I slept three good hours."
Pros: "Better than average entertainment system for domestic flights."
Cons: "Boarding done against logic: my seat was in the last 5 rows of the cabin and I was scheduled to board in the final group. When I got to my seat the first 30 rows were nearly fully, but the back of the plane was half empty. The whole time the gate agent was urging passengers to move faster through the aisle, but Delta should really rethink its boarding strategy. It shouldn't take 40 minutes to board a 757."
Pros: "Transfer f from first flight leg"
Cons: "Food and the 757 lay out"
Pros: "Great service"
Cons: "Look, if your kid is so young that he can’t get in a plane without screaming for four hours, you shouldn’t bring him on a plane and subject 200 people to that. It’s rude and selfish."
Cons: "Sat on the runway for over an hour to get the gate. Unacceptable."
Pros: "The flight was very good, no complaints, good service and we flew on schedule"
Cons: "We were split into two boarding groups, one for priority and one for everyone else. This was good but the priority line was just a bit too far away for the announcements to be heard. This added a little bit of confusion. This was at gate B36 at JFK Airport's Terminal 4."
Pros: "Didnt expect dinner but was served"
Cons: "Delayed flight, offset entertainment, touch screen un responsive"
Pros: "Everything went smoothly - very happy"
Pros: "crew kept a great attitude throughout"
Cons: "Having to find my boarding pass to deplane"

Cons: "late leaving, arriving and taxing."
Pros: "They were comprehensive and tried to move fast"
Cons: "Delayed flight because they didn’t had the crew ready"
Pros: "Boarding was fine. And service was good."
Cons: "TV controls didn’t work. So I couldn’t watch anything for the 4+ hour flight."
Cons: "See above"
Pros: "The movie selection is very good"
Cons: "Both boarding the flight and getting off the flight were severely delayed. The flight attendants also seemed to ignore half the plane when handing out drinks and when picking up trash. I had to flag someone down after they had simply walked past my row both times."
Cons: "Got in early"
Cons: "Flight was delayed by 2 hrs. Annoying!"
Pros: "What an easy flight. Run very well!"
Cons: "The crew seemed a bit tired, but it’s the season"
Pros: "Being on time."
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"
Pros: "The temp"
Cons: "It was too hot."
Pros: "It got me to SFO earlyish"
Cons: "Was told to go away and wait for name to appear on screen for seat assignment. Was seated apart from travel companion. Got to sit next to folks with questionable hygiene, seat broken. Seatbelt broken. Stuck in back of plane window seat and was supposed to be “happy”. I was brilliantly ignored by crew. Seat back entertainment broken snd flight crew never answered the call button. Got to watch bag handlers throw and drop luggage like true gorillas. Delta, this time you truely are the worst. Wont book you again."
Cons: "Delayed for an hour and fifteen minutes"
Pros: "The crew on Delta create a welcome atmosphere every time I have flown with them."
Pros: "The entertainment options and noticing the little touches that Delta is making to improve the brand and experience."
Cons: "Seems like there are legacy "attitude" issues with the crew. I sat on the aisle yesterday, and SEVERAL times I was bumped, quite rudely, by passing crew. In one instance, as they passed to pick up trash, they took two of my three items. They started walking on, and I tapped them as they passed to pick up the third. She brusquely turned and said: don't touch me to get my attention. No please; quite rude, and unnecessary."
Cons: "Horrible wait if nearly 30 minutes after landing"
Pros: "The boarding was efficient"
Cons: "Three hour departure delay. No explanation given. No apology."
Cons: "Flight was delayed for very 4 hrs sat in plane for 2.5 of those. Flight was delayed dye to strike in Barcelona. But replacement plane had fueling problems delaying the flight another 2 hours"
Cons: "Zero communication to the passengers as to why we were delayed for almost an hour sitting on the plane"
Pros: "Crew was polite"
Cons: "Rocky takeoff"
Pros: "I didn't like anything about this flight. Only benefit of the doubt is the 2 hour delay as a runway in SF had shut down."
Cons: "We had seats at first where there was what looked like bubble gum bits stuck on one of the food trays. The flight was clearly not cleaned although it landed 2+ hours before the departure. We had to ask for a wet tissue and clean it up. That was of no use too as it wouldn't scrub off. My wife was feeling under the weather and so we asked for a blanket. The blanket was hardly a blanket and more like a towel. We then luckily could switch seats as there were 2 vacant. But, the air conditioner was leaking water in the seat to our left. The crew was callous and just stuck the passenger with some napkins saying it does that. I don't fly Delta a lot and my experience in this trip isn't inspiring much confidence."
Pros: "Both flights were on-time, no gate changes. Staff was friendly enough, and seat back entertainment was appreciated. Everything went as you always hope it does for flights!"
Pros: "Decent food and drink. Flight attendants were very nice, although not quite as excellent as on the other Air France flights which I had on this trip"
Cons: "The seat is angled when fully reclined so there's a feeling that you'll slide off the seat, making it difficult to find a good position to sleep. Video screen seemed quite large. Headphones were noise canceling and worked well"
Pros: "Delta treats diamond medallion members better than any other airlines treats their elite members"
Cons: "No in seat entertainment"
Pros: "Seats were comfortable"
Cons: "Provide coffee at least"
Pros: "Crew was extremely friendly and professional. Well trained, exceptional."
Pros: "On time. Fast boarding. Comfortable seating."
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: "entertaining system"
Cons: "food could be better, not bad though"
Pros: "Plane was clean"
Cons: "My belongings stolen"
Cons: "Delays, seats are cramped and uncomfortable"
Cons: "Never made it to Chicago, rerouted through Washington DC."
Pros: "On time departure. Early arrival. Lots of seat back movies."
Cons: "Need more new releases for movie selection."
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."
Pros: "Made it home."
Cons: "delays."
Pros: "Nothing"
Cons: "Was missed due to delayed flight"
Pros: "Arrived early."
Pros: "nothing"
Cons: "no inflight entertainment no outlets"
Pros: "Awesome roomy seat right behind business class. Could not have asked for better! And it was a gorgeous new aircraft."
Pros: "I love your entertainment selection. also the comfort of seat and it's on time."
Pros: "The seats actually had individual screens, which was a very nice surprise. There’s a decent movie collection. alao the flight attendants were very nice and friendly."
Cons: "The tv show selection is quite poor. Also, like the previous flight, my husband and I weren’t seated together (not even in the same row) and when I tried to change it online, the entire flight showed as booked. However once on board there were clearly a number of empty seats."
Pros: "I really enjoyed the entertainment available."
Cons: "A 6 hour flight in which we were not offered food. In addition, when it was time for baggage claim, I noticed that my luggage had been damaged. One of the wheels was broken off. I put in a claim and have yet to hear back."
Pros: "The boarding process was ok."
Cons: "The entertainment system failed again."
Pros: "Sightsee"
Cons: "Delayed"
Pros: "Quick and did good job"
Cons: "After flying Japan Airlines I wish there were more free food and entertainment"
Cons: "No personal TV for entertainment"
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: "The boarding was done well"
Cons: "This was a 6 hour flight so American could at least have offered a better choice of in flight food purchases"
Pros: "Quick boarding, near empty flight."
Cons: "N/A"
Pros: "Landed early"
Cons: "The seats were not as good as the ones on my BA flight to Heathrow and then Rome. Also, cross country flight but no in flight entertainment. Arrived early in PHL and American would not let me move up to an earlier PHL-SFO flight since it was a code share booked with BA. Should not be my fault as when booking it indicated all four of my flights were with BA. Once booked it indicated the return flights were code share with AA. American should have allowed me on the earlier flight. That would have opened a seat on the scheduled flight which had people waiting on standby."
Pros: "Friendly crew"
Cons: "No entertainment."
Pros: "Loved the entertainment features. Great movie selection!"
Cons: "Nothing"
Pros: "extra leg room but I had to pay for it"
Cons: "This should only be used for important communications. And to not offer food on a 6 hour flight is horrible."
Pros: "Comfortable seats."
Cons: "Internet slow to access."
Pros: "blanket made it comfortable"
Cons: "No entertainment options"
Pros: "See above"
Cons: "See above"
Pros: "No entertainment nothing"
Cons: "Nothing"
Pros: "The flight crew was great and it was a very smooth landing."
Cons: "Had to pay extra for seats so we could sit together, near the front of the plane (not really, and no bathroom nearby, very small seats with zero legroom). we were delayed twice (40m then 1h10m) then told to go to a different terminal because now our flight WAS leaving on time! so we hauled over there only to be delayed again several times. we know it was a weather thing, but just wish there was more accurate info about when we would actually take off. seats on outgoing flight from SFO to CLT were GREAT, very roomy, comfortable. Coming back- not so much."
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: "Good free entertainment. Thanks."
Cons: "No good free snacks. Only free drinks."
Pros: "Entertainment"
Cons: "Same as above"
Pros: "Nothing absolute nightmare .. no water .. are you serious"
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: "Old plane"
Cons: "Sits were not comfortable."
Cons: "My flight was delayed for 3 hours and they where rude about my flight being delayed"
Pros: "The actual flight was fine."
Cons: "The gate staff was so rude."
Pros: "The crew was excellent, timing was superb,"
Pros: "tv!"
Cons: "babies crying"
Cons: "Food was expensive and not well put together."
Pros: "Flight attendants very kind"
Cons: "Arrived twenty minutes late. AA refused to accept responsibility for this and compensate me, even though my transportation had departed without me as a result of their tardiness."
Cons: "More water, drinks. The food was absolutely horrible."
Pros: "The crew was so friendly and accommodating."
Cons: "On my San Francisco to Panama City flight my vegetarian meal was not there. It wasn't a big deal in the end because I slept through most of the flight. I do find it odd though that on all of the other legs of my trip I had my vegetarian meals."
Pros: "Delayed but we arrived almost on time"
Cons: "Terrible that United charges for Carry on bags!!! Most airlines don’t do that but this is almost getting like flying in other low cost airlines. The price was not super competitive and on top they give you mediocre Seats, they split your family members just to push you to pay for the upgrades."
Pros: "Seats were very comfortable in first class. Very happy with that experience for short haul flight. Enjoyed the service. Flight attendant checked on me multiple times and offered beverages."
Cons: "Snack/food choices."
Pros: "Safety of the flight, the route"
Cons: "The remote for the AV was so torn. I coukdnt even use it"
Pros: "Safe flight. Also, I was offered a different flight from Boise, ID, in order to make my connection in San Francisco. Thank you!"
Cons: "NA"
Cons: "Legroom, bin space, food"
Pros: "No entertainment. Not working No internet. Crewfelt like they were forced to be “nice”."
Pros: "the entertainment program was good, and the plane in good shape"
Cons: "food was terrible"
Cons: "However flight from Athens to Munich sucked. Charged for carry on at check in , even thou others before boarding were checked there’s for free since flight was full. If that was the case I should of gotten mine free. Wish United would drop Lufthansa airlines."
Cons: "I saw your email informing me that departure would be delayed almost an hour, that was sent 50 min after its scheduled departure. By then I was out of the airport, picking up my car in long-term parking, and making my miserable way back home. It was a 3 and a half hour drive to get there."
Pros: "I enjoyed my interaction with the other passengers."
Cons: "Several delays compounded to make trip a lot longer and far less comfortable than it needed to be."
Cons: "That I could only have one carry on an my purse was considered two, really and it was a small purse."
Pros: "But the amenities were terrible. I couldn’t figure out how to operate the in-seat video feature plus there was no food. Leg room was too cramped also."
Cons: "See above. Amenities were terrible as was leg and seat room."
Pros: "That I didn't get dragged off the plane and I landed alive."
Cons: "Everything else."
Pros: "Everything about customer service was great, unfortunately both fights got delayed making it for an extremely long day."
Pros: "Good rate"
Cons: "Didn’t like that I had to check my own bag in and still pay a fee. If your going to charge me then your staff should check my bag. Also I’m not a heavy person i workout so my shoulders are big. Your seats are to small"
Pros: "On time, quick boarding, smooth flight"
Cons: "No issues"
Cons: "Crew was rude and seemed to be in a constant rush big lack of customer service"
Cons: "Now Sherry in any documentation I received did it say that my flight was operated by United airlines. I waited at ANA check in until within the 2 hour window and went around and asked someone at United who confirmed that they were partners with ANA."
Pros: "Ordered the Protein Box, it was ok.. crew members nice."
Cons: "The Smell on the flight was unacceptable, I was sitting about a couple rows across the middle bathroom, and it smelled horrible, I had never had an experience like this on any other flight, I fly United many times a year, and this had me really uncomfortable for almost 5 hours, since the flight was delayed almost 1.5 hours while we sat onboard the aircraft at the gate, that had me miss dinner plans too in San Francisco as well. I really hope they can fix that, For the good of the passengers, felt like I was going to be nauseous all the time, and I'm really not someone that complains or takes time to review badly."
Cons: "Plane was supposed to depart at 5:30 did not depart until around 7:20!!! Had to sit on plane for almost 2 hrs!! We were NOT OFFERED anything to drink Not even water!! Jet Blue would NEVER be neglectful, they are very service oriented. Plane was full & 2 babies on board one was fussy crying at times. It was s nightmare!! I was exhausted from traveling to NYC & Philly! & the delay & lack of service was AWFUL!! Could not watch TV, bc It either connects to phone, I could not connect it or I think you had to pay! Unheard of!!!I love to watch CNN, MSNBC & Fox it makes the time fly!! Hopefully will Never have to fly United Again"
Pros: "Nothing"
Cons: "Will NEVER fly United again. Going home to advise EVERYONE I know not to fly United. They straight suck. Starving people on long flights with hot food for a third of the plane?!?!?! Then telling me I'm wrong for expecting a meal on an almost 7 hour flight?!?!?! &, even better, the reason my son & I starved all morning, day , & evening because EVERY single flight (all 3) were late, one so much so that we almost missed the connecting flight. Wow, is all I can say. After I still have United a chance after assaulting that poor man. Beyond highly disappointed."
Cons: "The Overnight flight I had was EXTREMELY uncomfortable. Too uncomfortable to even sleep at all. The seating is so tight, I could barely move my legs when the seat in front of me was reclined (and I am tiny!) I landed after my connecting flight was already boarded, causing an employee from the airline to announce my name over the intercom on the plane and tell the passengers to "clear a lane for me." I ran with my suitcase over my head, bumping into people and making it to my next gate...where I was told there was ABSOLUTELY NO ROOM for my carry on...which was also, very tiny. I specifically did not want to check my bag because I needed to immediately hop off the plane to make it to work on time. Another customer was VERY upset about having to check his bag and was pulled aside. I finally was told I needed to check my bag at the gate to get on. So i did. As I entered the plane, about half of it was COMPLETELY empty with PLENTY of room. I was floored. About 10 minutes later, the very angry man happily entered with his carry on and stored it easily in the overhead bin. My frustration was at a peak. But I said nothing. When I arrived to Newark, I rushed to baggage claim and guess what? After 30 minutes of waiting, my bag never showed up. I had to check in with information and finally found it. But this caused to me to be late for work. I have usually had a great experience with United. But this experience has changed my mind completely and am very upset."
Pros: "I liked how quick and easy the flight was; from boarding to exiting the plane in SFO."
Cons: "The size of the plane."
Pros: "After having to spend an unplanned night at a airport hotel due to "air traffic controller conditions" that made it impossible to connect to a 2nd flight home, the next day early morning flight went flawlessly. We were upgraded to Economy Plus seats on a new 737 which had ample overhead space. The flight crew and boarding agents were all courteous and attentive."
Pros: "Missed connection in SF to Medford due to other planes at our gate not allowing us to de-board on time to make my connection to Medford ...!!"
Cons: "The day we were to return to San Francisco United cancelled our flight making us scramble to get another flight. Thank goodness for Alaska. They got us a return flight and went to Seattle instead of San Fransico. United and San Francisco is a joke. Never again."
Cons: "Flight got cancelled cause of issues with plane. Took over 5 hours in line to get to the counter to talk to someone. There were only 2 counter people for first 3 hours. Once at counter ther had to put us on flight for next day. (Just informed 5 min ago that flight has been delayed another day cause of plane issues.) they couldn't get us to sit together which I understand but also put me in a middle seat which I'm clostraphobic so that sucks. Told me that I can book a hotel to stay at and they would reimburse me.... eventually. Fought over that for an hour and they finally agreed to pay for Hotel. Overall the trip was great but the departure from Kauai has been real bad. Still waiting to leave the island."
Pros: "Crew was attentive."
Cons: "From Gregory at the check in being rude and anything but welcoming, to seats in first class needing replaced, this was anything BUT a first class trip. This was my second time giving United a chance as I normally fly Delta. I don't think I'll make that mistake again. I understand a late night flight doesn't have a meal service, but snacks of chips and bananas is not my idea of how you should serve Firat Class passengers. I would have a hard time recommending anyone choose United as their airline. Time for an upgrade of not just the seats, but overall customer service."
Pros: "arrived on time, newer aircraft"
Pros: "United is definitely improving. The service was attentive and friendly. When I asked for PJ's, the flight attendant made a good effort to retrieve them for me. I slept through the entire flight, very rare unless the conditions were optimal for sleep."
Cons: "While this flight was fine, my flight to Taipei was riddled with poor service. A bad and forgetful flight attendant can make all the difference. As United adjusts their service to the new Polaris configuration on newer planes, conditions will hopefully improve."
Pros: "The seats were uncomfortable. The staff was cold. The food was horrible, I wasn't even able to eat some of it. The chicken was full of bones and grissle. The rest just tasted bad. Most of their planes did not have screens in the back of the seats. Instead they wanted you to watch on your personal device via their app which worked sub par. The baggage on the return flight was delayed and I almost missed my next flight even though I had a 2 hour 40 min layover. Thankfully that flight was delayed 1 hour and a half. Next time I will stick with airlines I know better. Delta, Emirates, and Qatar all offer superior service and upscale aircraft. The 2k spent was not worth what I received."
Pros: "the crew , the services ."
Cons: "They don't respect their seats . And they let seat a strong smoker on my side and his seat was begin me . 3 costumers don't seat on their own seat all mix it aaaggghhhh"
Pros: "Anytime things are new, and the basic needs are met for service, I think people will be happy. But! Timing was estimate for an 8:56 arrival and we landed at 8:30, so great timing too."
Cons: "Power outlets worn out and won't hold a plug so they are unusable"
Cons: "Flight was cancelled"
Cons: "Overpriced food that didn't look good and very expensive entertainment options"
Pros: "Economy+ seats were very nice. The stroopwaffel snack beats Delta hands down. Check-in was smooth and we had no hiccups."
Cons: "The boarding lines were not clearly delineated. It seemed like there were gate check offers, but audio systems at the gate were not very coherent. Paying for Direct-TV is so-so."
Cons: "Wifi should be free"
Pros: "The crew was friendly"
Cons: "The a/c on the plain was not very cold and it needs to blow more air"
Pros: "Nothing"
Cons: "Entertainment from the 80s. Meaning one TV screen on ceiling. Violent entertainment for kids Uncomfortable seating. No power outlets and very old plane. Reminded me of traveling back in the 80s Adding all this to an 11 hours flight makes it a very undesirable flight. I understand this was a Lufthansa flight operated by United Airlines."
Cons: "Were held up by TSA in San Francisco because we were not given receipt for our dog who traveled with us. (We had a 2 hour layover in SF and took dog outside the security area for relief). Then the ticket counter in SF was understaffed and it took a long time to get the receipt printed (Once at the counter the agent was very helpful, efficient and quick). Should have a pet area inside the security of airports, like Palm Springs does."
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."
Pros: "Flight was 15 minutes early, which helped with a tight connecting flight. Crew was very kind and understanding to this fact."
Cons: "My seat was switched to a middle seat with no reason or justification."
Cons: "Had to sprint through the airport to make a connection because the flight was delayed and then went to a gate in the international terminal which was far across the airport from my connection."
Cons: "Purchased tickets 4 months before this flight for a departure time of 6:05pm. Tried to check in and check baggage at 9:30am but was turned away saying I could only check in 3 hrs prior to my flight. Came back at 3:00pm to check-in and they could not find my information. An hour later they find out that they cancelled the flight and moved my departure time to 8:25am for that day. They say they emailed 3 times in May but I never got it (I'm a bit crazy about my email staying clean) so they say it might have went in to my spam folder due to they types of emails they send to customers. They only kept repeating that they notified me so there is nothing they could do. I ended up going to Air Canada to get a flight to PHX the next day. No apology, no help, no hotel for the night...Terrible experience by United. They gave me a customer relations group contact information to follow up with for complaint but since they sent me the 3 emails in May about the change, they have no liability to fix the situation."
Pros: "Even though the flight was delayed on departure, it did not cause a delayed arrival. The crew was professional and courteous."
Cons: "There was very little legroom in economy seating. My knees touched the back of the next row making a very uncomfortable 5 1/2 hours. I think it is ridiculous to have to pay additional fee (up to $99) for extra legroom. I think it is called "premier economy" seating."
Cons: "Old plane - no build in screen/entertainment system! Only access would have been thru WiFi, but servers were down pretty much all the time. Most movies would have required a specific app, which was also not accessible."
Pros: "Flight was nice, clean and crew was friendly."
Cons: "Food was pathetic, entertainment system was old, no independent entertainment system on board, aircraft looked outdated."
Pros: "The crew was very attentive to each guest."
Cons: "Well I paid more for a lesser quality plane ride... didn’t like that very much."
Cons: "Snacks"
Pros: "Everyone was helpful and friendly."
Cons: "Not charge so much for luggage and carry-ons."
Pros: "The crew was very friendly."
Cons: "Flight was late, excessive baggage fees, plane was dirty, there was trash under the seats in front of us."
Pros: "Was direct and easy. No issues with boarding or flight"
Cons: "Cramped"
Pros: "Nothing"
Cons: "I will never fly Frontier airlines again. No matter how inexpensive the tickets are, it is not worth the aggravation. Agents were rude. Flight horribly delayed. Plan ride was uncomfortable. I lost my car rental because they close at 5:30pm. When there own employees say there flights are always delayed that alone said it all."
Pros: "THe passengers were well behave during and polite"
Cons: "The 2 hour flight delay"
Cons: "The crew was rude to the passengers. They charge form 9$ to 40$ for seat selection. Charge for a Carry on bag (anything that doesn't fit under your seat). The flights had maintenance issue, hence delayed. I will absolutely avoid traveling with frontier in the future."
Pros: "Nice new clean plane"
Cons: "Connecting flight was delayed by one hour!!!!!"
Pros: "I arrived safely. The crew was very friendly and helped to. All my husband who was scared as this was his first time flying."
Cons: "The agent who checked me in was extremely unprofessional. I felt like she was envious that I was going on a vacation and she had to work. She tried to make my experience a living hell. I personally think she should be fired. She does not enjoy what she is doing. She joyfully told me that it costs $40 to carry my luggage and after I informed her that I saw it online for less she informed me that I should have bought it online. She then stuck me all the way in the last row of the plane. I am 5'9". My husband is 6'2" and over 300 pounds. Those seats have the least leg room. It was pure torture. The flight crew in the back help my poor husband by using humor to help him."
Pros: "Although the flight was delayed half an hour....I was happy with the service and crew."
Cons: "A free juice woulve been nice....but oh well...no one's gonna die of thirst in 2 hours."
Pros: "Boarding was smooth and efficient. Crew was very nice and accommodating."
Cons: "Seats were very uncomfortable and didn't recline which made it tough to sleep. Also complimentary soft drinks and snacks should have been offered. Shouldn't have to pay for them."
Cons: "Uncomfortable seats - don't recline! Rude crew, create an impression if they're doing you a favor by being there. Flight significantly delayed. No clear announcements. As a frequent flier, didn't expect a Spirit like experience from Frontier!"
Pros: "Nothing."
Cons: "After paying for the flight. We had to pay to get seats guaranteed next to each other. And the charges for everything including a ridiculous amount for a can or soda or water and a snack."
Cons: "if flight was delayed should at least provide complementary soft drinks..."
Cons: "There was a malfunction online and I was overcharged for my flight. There were also delays going to and from my destination."
Cons: "The seats couldn't recline plus they were very uncomfortable to be in."
Pros: "The crew was friendly and helpful."
Cons: "There were extra fees for carry on and checked bags, which was not revealed until we printed our boarding passes. In addition, we had to pay to reserve seats. On top of that, I have never sat in such uncomfortable seats. They charged $2.99 for a can of soda on the flight. Finally, they lost our bag, after our flight took an hour longer than it was supposed to."
Cons: "5 hours late, no updates sent via text or email, $15 dinner boucher useless and given after restaurants closed. I will never fly frontier airlines again!"
Pros: "Nice crew. Plane clean."
Cons: "On this long flight from Atlanta to San Francisco, a reclining seat would have been nice."
Pros: "The seats were comfortable and the thin profile gave a feeling of roominess."
Cons: "Baggage fees and carry of fees. You can save by paying online but I didn't learn that until the second time around."
Pros: "The initial price I paid. Which was very reasonable for a non-stop flight."
Cons: "Paying for a checked bag. Paying for a seat so I could be assured a decent seat. My decent price soon became what I would pay on any major airline. So why would I fly Frontier?"
Pros: "The crew was friendly and helpful."
Cons: "Had to sit on the tarmac about 30 minutes on arrival in Indianapolis because another aircraft was at our gate. Why couldn't we have gone to a different gate? Arrival was at about 9pm and the airport wan't that busy. This was uncomfortable. Would have been a good time to hand out free snacks and beverages or drink coupons for a future flight."
Pros: "Little."
Cons: "Worst flight of my entire life."
Cons: "Flight was significantly delayed. Advertised as low cost, which it was, but that is because they make you pay for everything except water. Seats do not recline either...bad for red-eye."
Pros: "Nothing."
Cons: "The flight was delayed for over 4 hours due to operational issues (not weather or maintenance). The gate representative didn't keep us informed of the issues and when he did, he was usually wrong. There is a surcharge for everything from carry-on fees to beverages on the plane. The plane itself was uncomfortable with uncushioned seats. Let's just say that if I had to choose between a Frontier flight and a Delta flight that was $400 more, I will choose the Delta. Same goes with any competitor. I will never fly Frontier again."
Pros: "There was a 4 hour delay on both flights. What a HORRIBLE airline. They issued me a 100.00 voucher for a future trip, which I will NEVER use. I will not fly fron tier ever again."
Cons: "Everything. You have to pay for all luggage, drinks, everything. In the end, it is Not the cheapest because they charge for toilet paper. Oh get this, you cannot recline. That cost extra. Never fly FRONTIER."
Cons: "Operational failure by Frontier made the flight late and chaotic."
Cons: "It's very late to get a hotel and they didn't arrange anything for us. We get a credit for future flights and hotel reimbursement. But I'd rather not fly Frontier again!"
Pros: "Did have good leg room in exit row."
Cons: "Thought we got such a good deal on flight, but had to pay extra for carry-on and even to choose a seat. The seats did not recline, but maybe that was because we were in exit row. Boarded an hour late to clean up from last fight because of (per their announcement) vomit."
Cons: "Frontier charges for seat assignments and even carry-on bags. It's the #1 airline for indignities and nickel and diming its passengers."
Pros: "The crew and neatness"
Cons: "Entertainment"
Pros: "I do not normally complain, but my two flights this weekend were more than an hour late each, coupled with horrible cramped seating, unfriendly flight crew, tons of extra charges, and a dirty plane. I will be trying to avoid frontier flights on the future."
Cons: "See above."
Cons: "Flight had uncomfortable Seats was delayed 1.5 hours and the baggage took more than 30 mins to come out"
Pros: "Nothing."
Cons: "Got a cheap flight but little did I know that that would be offset by being nickeled and dimed for seats, bags, and drinks. On top of that th plane was five hours late from its start point and the only information the gate agents would give (with an attitude) was the plane was coming. I called customer service to see if they were offering any restitution for this, and I was told that's not up to him. I will never never never fly frontier ever again."
Cons: "I was seated between an overweight man and a very tall man, both of whom felt as though their sizes allowed them to infringe upon my space. There were plenty of open seats on the flight and yet no effort was made to alleviate this clear problem."
Pros: "The time of the flights, and the quick security at the terminal."
Cons: "Hidden fees for everything. You book your flight for one price. (mine was about 100$ less than other airlines at time of booking) -Then they have you pick your seat (charge) -Then if you want to check a bag (charge) -Then if you want to BRING A CARRY ON (CHARGE) It ended up being way MORE than the other flights I could have just booked on other airlines. (I booked at $220.00 and by the end of my trip spent $373.00 with Frontier) Also, the returning flight was delayed 45 minutes but I received no notifications."
Pros: "The flight was right on time leaving and arrived early. The planes are new ."
Cons: "the boarding pass was wrong. The check in clerk forgot to tag my bag with the any tag.so it stayed in Phila. They did deliver it on Wednesday to my house. Thank you."
Pros: "Seats were comfortable and I arrived safely. Grateful for these aspects of my trip."
Cons: "Employees were rude. Inaccurate information about flight times provided before and during the flight. The hidden fees were ridiculous, such as $1.99 for seltzer water. Note that you cannot pay in cash for anything. Not so unusual, but a pain for since my debit card was lost. Because flight times were inaccurate, I had no time to buy food during my layover and wasn't able to purchase food on the flight. Overall, I would NOT choose to fly Frontier Airlines again unless absolutely necessary."
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."
Pros: "The staff"
Cons: "The plane, the five-hour delay."
Cons: "Boarding was bad, after a delay it seem as if we were rushed onto the plane to make up time."
Cons: "I arrived at the airport extra early due to the long TSA lines. However frontier would not check my bags until 1:30. I waited an hour to check before being able to going through security."
Pros: "Nothing"
Cons: "These flights are horrible- hard cramped seats, no services, not even a cup of coffee unless you pay extra. $40 to bring a carry on bag on the plane. Cost more than any other flight in the long run."
Pros: "Boarding process was easy Crew were attentive On time I didn't pay for a seat, but got an aisle anyway"
Cons: "Checked bag and seat fees Seats do not recline Charge for water! Tray tables are half the size of typical trays, but I guess since they don't feed people, it's not much of a problem"
Pros: "Flight left and arrived on time."
Cons: "Seats didn't recline and website is misleading when it comes to purchasing seats. I was very uncomfortable."
Cons: "Getting nickeled and dimed for everything from carry-ons to seats to drinks. Uncomfortable seats"
Cons: "I didn't like how we were notified last minute about our flight being delayed for THREE hours. There was no voucher offered as well. Completely terrible."
Pros: "Smooth flight, courteous staff and on time."
Cons: "Be sure to get there definitely two hours prior due to their strict policy about boarding. It would be nice to offer something for their flight, snack, etc. At least water."
