Pros: "N/a"

Pros: "The crew was nice. They did a very good job under the circumstance."
Cons: "The flight was delayed over an hour because of an error on Delta‘s part. They did not verify people as they were boarding. Further the person in 17 F was doing video chat as we were preparing to take off and he had very foul language throughout the flight. The crew never said anything."

Pros: "Missed it"
Cons: "Give back money"

Pros: "Actually leaving the airport after 2 hours late was the best part."
Cons: "Not be hours late. And then when you finally land have to wait longer for an open gate cause they're doing work on the other ones. A lot of poor planning on this trip. Very disappointed in this experience cause I love to fly."

Pros: "Friendly crew. Landed early."

Pros: "Seat was comfortable"
Cons: "The temperature, it was kind of hot."

Cons: "Safe and happy travel!"

Pros: "Good communication about weather and delay"
Cons: "No delay. Consider dropping the $75 standby fee."

Pros: "Not much I liked"
Cons: "The crew were the worst Delta crew I’ve ever had. Sat 1st class and waited 1 hour from sitting in my seat untill I was offered a beverage. Asked for a snack and was told to wait until the basket was brought around, 20 minutes later. Asked for coffee, it was terrible and served with attitude."

Pros: "VERY small plane and small narrow seats"
Cons: "Yes...not change my flight at the last minute and causing me to miss my connecting flight. Then making me reschedule my flight with only options that I now have (2) layover and then arrive in Korea another day later, that then caused me to miss my college orientation day!"

Pros: "small and uncomfortable"
Cons: "respectful size seat"

Pros: "On time this time"
Cons: "Nothing"

Cons: "No video screen"

Cons: "The comfort seats are not that comfortable"

Pros: "This was my daughter’s first solo travel home from college. She said the staff was helpful and kind. She loved that the flight was not over crowded. It was a smooth flight."
Cons: "Only negative thing she could say was her flight was delayed an hour. But that isn’t terrible considering all the holiday travelers."

Pros: "Good customer service in person"

Pros: "chwcking in was very easy."
Cons: "No in board beverages. On flight from RDU to PHL beverages were served."

Cons: "I had a 4 hour layover in Minneapolis, there was another flight to Denver that I meant I could’ve been home three hours earlier had I done standby, but because I had a cheaper ticket I was not allowed that opportunity. That makes absolutely no sense to me seeing as my flight was packed. I’m sorry my flight saved me money"

Pros: "Not like"
Cons: "I have Sky Team Elite Plus Platinum but not fare anything!"

Pros: "the flight was quick and it was fine. flight crew was polite and professional."
Cons: "i didn’t like that my knees were in the row in front of me, and we hit some pretty scary bumps. i get really anxious about turbulence."

Pros: "Ease of check in and friendly people"
Cons: "Marta"

Pros: "Did not wait for luggage."
Cons: "Food was marginal. Equipment had low ceiling under carry on shelf. No entertainment."

Cons: "They cancelled my ticket and did not inform me. Horrible exlefywith JustFly.com Beware of this organization"

Pros: "The exit row seat on this leg out of PHL to SLC did recline! No need for Delta Comfort+ unless you want to get off of the plane ... faster."
Cons: "For some reason, the pilot couldn't figure out how to adjust the cabin temperature for the first hour or so. This made the flight (and I was sitting in an exit row seat, right by the door which is usually cooler) uncomfortably hot and muggy. Food? No food. Thank goodness for Delta Lounge (even if it was the one in PHL). Just snacks make this a poor option for many. I don't know what is up, but the USB charger on the two monitors didn't work and neither did the outlet between the seats. And I have two different sets of cables "just in case" and they're the 3-in-1 so I can try to charge multiple devices (Apple, Android and Samsung) but nothing worked."

Pros: "Staff personalities"
Cons: "Waited extra 20 mins after door closed to-complete loading luggage"

Pros: "Staff was very courteous, the flight was smooth."
Cons: "There was no TV's on this flight."

Pros: "There was one helpful lady"
Cons: "Flight was rerouted and rebooked twice. I’m stuck in Detroit overnight, and won’t be getting to Monterrey until tomorrow afternoon. Thanks, delta!"

Pros: "The staff"
Cons: "Nothing"

Pros: "Uneventful flight - boarding was great and there were no hassles."
Cons: "No food. No onboard entertainment."

Pros: "Flight attendants were really kind"
Cons: "We were an hour late to leave so I missed my connecting flight and am currently stuck in Minneapolis for nearly 8 hours now"

Pros: "Stewardesses were sympathetic but could do nothing."
Cons: "A few flurries out of Philadelphia and flight is delayed 2.5 hrs, we therefore miss our connection and all they wanted us to do was spend 2 days in airport until next flight. Finally reached a compassionate soul at customer service who got creative and routed us to BCN via ATL, Miami and Madrid."

Pros: "Got upgraded to 1st / Business class."
Cons: "Due to weather the power outage in ATL, the flight out of PHL was delayed by about 30 minutes. No movies. No meals."

Pros: "We were probably in the air for 30 mins; great short flight. Plane wasn’t filled so had plenty of space."

Pros: "Crew was very attentive and curtious. Boarding was a bit more chaotic than usual and the gate agent made no announcement about boarding procedure, which certainly contributed to the scrum resulting. I arrived from the Skyclub several minutes prior to boarding time and was unable to find a path through to the Priority Boarding Lane. As boarding began she had to redirect at least seventy-five percent of those in front of me as they were not in First Class. Had she made one or more clear announcements about boarding procedure I rather doubt such a misunderstanding would have occurred with so many."
Cons: "For the third Delta flight in a row (all First Class) the crew did not make any effort to keep economy class cuctomers form storing bags in the First Class overhead or using the only First Class laveratory during flight. This flight I was unable to utilize the laveratory even once due to this excessive and continuous useage. Trying to do my bit to reduce our carbon footprint, yet I am sorely tempted to return to charter service when disrespect of the airlines own basic service class rules gets piled on top of TSA hassles."

Pros: "I had a window seat"
Cons: "bumpy flight"

Pros: "Flight attendant insisted to take my jacket. She didn’t return led. I forgot jacket in Cincinnati"
Cons: "I need my jacket"

Pros: "As usual, Delta staff and crew did their best to make the flight quite enjoyable and smooth."

Pros: "one i got to gate i could relax"
Cons: "scary making connection from AA flight arriving int'l terminal"

Pros: "I appreciated the kindness of the staff at each of our stops. From beginning to end they were polite, helpful, and kind!"

Pros: "All crew was great"
Cons: "We lost checked bag or it was taken, will loss a half day shopping for replacements. Compensation policy very unclear, not counting on getting any."

Pros: "Arrived on time crew worked had"
Cons: "my seat was BAD , no recline- right by bathroom one of which was out of order."

Cons: "Compared to such airlines like Turkish or etihad, service and comfort was lacking behind."

Cons: "On time"

Pros: "Liked the plane and the leg room. Had to switch itenary due to weather and the gate agent did a great job."

Pros: "Airplane was good, boarding was fast."

Cons: "The original flight was canceled and a new one substituted - basically they wanted to fly a smaller aircraft (via a different regional carrier) so the flight number changed. PHL did not have the new flight info displayed at the Departures board or on the screen at the gate. Caused a little anxiety."

Cons: "Cramped, uncomfortable tin can of an airplane. Barely tolerable for even an hour’s flight."

Pros: "Service was great. Seating was OK. It was a brand new vehicle, so the (climate/air handling) was great."
Cons: "Boarding was not well organized."

Pros: "The aircraft."
Cons: "Mexico needs a new airport."

Cons: "It was excellent"

Pros: "The service on the plane is ok."
Cons: "On the trip Mex to Bogota, the airplane belated to landed, around four hours after. First it was almost landed to Bogota, we were on El Dorado airport and then back to the air and then going to Medellin airport for landed. So they keeped us inside the airplane (I do not how many time, but maybe 1 an half hour inside) and then back to Bogota for landed. So it was awful and worried time."

Pros: "All waa good and timely. Comfortable and the crew very nice"
Cons: "I got home and my luggage had been all mixed up and they stole two watches. It’s sad that Aeromexico has employees who are thieves. It’s happened before and to many people I know. You should remedy this because it’s not right"

Cons: "N/a"

Pros: "the aircraft was incredible nice and clean. I loved it!"
Cons: "hello, the only thing I did not like was the air conditioner. It was too high and my eyes got very dried and irritated. From that everything was very good. thank you"

Cons: "Lack of snacks, prefer chips"

Pros: "Arrive on time, excellent flight."

Cons: "My luggage was ripped with a box cutter or blade."

Pros: "The plane was comfortable and the crew was great."
Cons: "The boarding was ridiculous. They never posted what gate the flight went out of. If it wasn't for Kayak we would not have known when to go. The flight was delayed but they never did update that information. It did not leave on time like the board said. They just all of a sudden said they were boarding the flight."

Pros: "The crew kept us informed and the flight attendants were nice awesome plane!"

Pros: "I enjoyed the movies on board, entertainment great!"
Cons: "This my 3rd trip to PVR on airline. As a delta frequent flyer I have always gotten upgraded or standby list. For what ever reason on my return it seemed staff working at airport today ALL gave me false info and finally in the end when I wanted to pay for upgrade told flight sold out ! False ! 3 Empty AM Plus seats 5 Ross in front of me . So I was separated from my friends as they sat in first class. I blame the gate staff since none had a clue ! Horrible e periwnce for first time at Mexico City airport. We also left Aweomexico lounge since was dirty and went to American Express Lounge that was clean z"

Pros: "Smooth flight"
Cons: "People make you feel dumb when you have a question or they need to repeat something they mentioned before. Is very hard to understand sometimes trough the speaker."

Pros: "Seats were comfortable, even in economy. Personal entertainment at each seat with a good selection of movies and easy way to navigate to English language. The flight attendants were very nice, and they provided not only drinks but also a full snack tray to each person. Flight was right on time and announcement were in Spanish and English which was important for me as I don't speak Spanish.."

Cons: "My luggage wheel was broken :("

Pros: "- Personal Media Station - Food - Water served at least twice - Fast flight"
Cons: "- Not enough space to fit my carry-on - No self service for check-in in the airport."

Pros: "Movies"
Cons: "Them sending us an email two and a half months after we made the reservation to change the outgoing flight causing us to have a six hour leftover."

Pros: "Airline stewards were friendly and provided good service. Seats had the television screen in the seats instead of the monitors that come down from the ceiling. Everyone could choose what they wanted to watch."
Cons: "Flight was delayed but that worked to our advantage since our initial flight was delayed. We would have missed this one. Only a couple connecting flights were announced by the flight attendant and where to go. Ours was not mentioned and no direction given on where to find our gate. We had to go to an information booth that only told us somewhat how to get to the gate. It was a long distance and we weren't sure if we would make it or not. Need to improve communication with passengers."

Pros: "very smooth flignt"
Cons: "boarding took a long time due to last minute checkups"

Pros: "Nothing"
Cons: "I arrived one hoyr before departure. There was absolutely no one in the counter to help solve my problem. I kept calling costumer service on the phone to get help. I had a first class ticket and all I got was someone in the airport will help you. But there was no one at the counter! More rhan 2 hours on the phone and they would not even let me talk with the supervisor. All I got was wait for someone in the counter... No one ever showed."

Pros: "For a 5.5 hour flight its ok, the seats have enough space, one meal is provided and a snack. Entertainment options were ok, a couple of new movies."
Cons: "Since we get to the airplane as soon as other passengers arrive in the same plane, it is not very clean, how much can they clean it up in 15min? Also, no pillows or blankets. This was not an economy or discount airline so I dont think its acceotable."

Pros: "Price and staff"
Cons: "Snack was a tiny bag of peanuts, plane was old and dirty, no in-flight entertainment."

Pros: "Good attention, well management of lugaje, wc clean"
Cons: "Creew elderly , poor food, no enterteniment, bad sound,"

Pros: "It got me on the way"
Cons: "An outlet and letting me get into Canada"

Cons: "The plane was extremely full. No chance of social distancing."

Cons: "Seats need to be bigger (wider)"

Pros: "The text messages from United"

Pros: "First flight I’ve been on where United airlines has adequate leg room for a tall person. A newish airbus plane. I’ve been avoiding United for a number of years cause their planes tend to be very uncomfortable for taller passengers. This is the seat spacing that all airlines should have."

Cons: "Nothing"

Cons: "Delay for 3 hours"

Pros: "The crew was fantastic!! Friendly and attentive!!"
Cons: "More snack options other than pretzels would’ve been nice."

Cons: "The boarding lasted much longer than I had anticipated. I was also not informed of when my group was boarding at the proper time."

Pros: "Well organized."

Cons: "Uncomfortably warm!!"

Cons: "The plane got delayed by more than 3 hours!"

Pros: "I was able to move my dear and get better leg room. Really appreciated that!"
Cons: "Teeny snack."

Pros: "It had movie screens quite old but better than none"

Pros: "Clean aircraft, swift flight"
Cons: "Seat was changed to last row/middle seat (not what initially booked or confirmed with online check-in). Before takeoff, attendant moved all passengers in back row to alternate seats. Which meant that I was no longer traveling with my colleague. Unfortunately, that made our intended meeting time impossible."

Cons: "Just give free wi fi already"

Cons: "I didn't realize how you can no longer be accommodated without being charged for everything."

Pros: "service on time"
Cons: "snacks very little amounr"

Pros: "I fly weekly, but try never to book United because there are always issues with my support animal. Without fail, regardless of the city, the agents at check-in do not know what to do. Each time I'm met with annoyance at having to check me in, and I usually end up calling either the disabilities desk and handing the agent my phone, or asking for the CRO. I have to leave an extra 45 minutes to accommodate flying United every time -- ridiculous. This time I also got a load of unprofessional gate agents cooing and awwing at my my support animal, and trying to pet him. When this happens I always simply state, "please don't" and this was key with rudeness as well. United please provide us with more professional and adequately trained staff at the airports. Once we're on the planes it's fine. But you seem to have VERY low hiring standards for airport staff"

Pros: "From check-in to touchdown, my travel over this Christmas was awesome! Flights were on time, security ran smoothly, and I would use Kayak again for sure."

Pros: "My flight stopped for over 2 hours for refueling which caused me to miss my coneccting flight, plus 2 other reschedual flights. Then no one would accomodate me on account of this. Never flying united again"

Pros: "All good, no complaints!"

Pros: "Everything went smoothe!"
Cons: "Not 1 thing."

Pros: "The seats and the price"
Cons: "How far back I was"

Pros: "Crew was great"
Cons: "Great aircraft!"

Pros: "Nothing"
Cons: "Delayed 3 hours"

Pros: "Tv"
Cons: "The tv kept shutting on and off"

Pros: "The leg room"

Pros: "Free beverage and snack. Flight attendants were nice."
Cons: "Sat inside the airplane for more than an hour! It was horrible. Why have the customers board the aircraft when crew members know that we're going to be delayed due to weather?! Ridiculous."

Pros: "The crew was nice and great with the three very young kids sitting in front of me. Left and landed on time!"
Cons: "Very cramped seating. The on flight entertainment kept searching for a satillite signal, only ever staying on for 30 seconds before searching for the next 3 minutes."

Pros: "The crew did the best they could with what was presented."
Cons: "Pilot should of gave us accurate times rather than saying "we should be taking off in another 15 min folks" which turned into 4 hours, pretty crazy."

Cons: "Flight was delayed, missed connection, chose to go to Minneapolis and was booked on a flight that I didn't have time to get to the terminal, so was rebooked a 3rd time, missed my shuttle, have no idea where my luggage is"

Cons: "First leg delayed on Tarmac for over an hour so I missed my connection. Then united rebooked me for the next day but gave me no voucher or money towards a hotel so I had to get one myself since it was all night in the Houston airport.mthem the rebooked flight had mechanical problems we had to change airplanes, and gates/terminals and were delayed another 2.5 hours. It was terrible."

Cons: "My connection to YYZ was cancelled and I was not even rebooked to the next flight. I needed to buy a ticket on Air Canada in order to get there. Every time I fly United I find myself asking "why in the hell am I flying United?""

Cons: "Very rude crew."

Pros: "Good service"

Cons: "Either ran out of or no snacks offered. Crew seemed a little impatient"

Cons: "Where do I start. Let's start with booking and the lack of knowledge, inability to listen and respond in an appropriate manner, and the fact that after I asked to speak to a manager due to the previous issues with the agent, and after being transferred all I needed was some understanding and support due to a family emergency and instead I get a short rude push back and then hung up on by the manager after I expressed my struggle and desperation for help. The lack of empathy and just the overall experience was beyond horrible, and if it wasn't for the desperate situation I was in I would have never used your services."

Pros: "On time bags made connection"

Pros: "It was a light flight, so I could have my carry-on with me even though I was in group 5. The breakfast -- berry pecan French toast -- was surprisingly tasty and satisfying (if not very attractively presented)."
Cons: "Too bad I had to pay so much for the exit row seat. I'm tall and it's needed for standard comfort (as opposed to extra comfort). Oh well. Gotta squeeze those dollars out of the passengers every way they can."

Pros: "The boarding was very smooth."
Cons: "The passengers behind me had a baby on board that cried throughout the whole flight."

Pros: "Got me safely to my destination. Other passengers were friendly and helpful. Sf and Vic airports nice. flight attendants passably pleasant. No food that I was aware of. Entertainment at least there was a wifi option since there were no screens."
Cons: "Check in agents all might as well have been robots, but with bad attitude. Even at the star alliance gold checkin desk the agent was clearly unhappy/furious (seem to be ongoing issues with the system/ machine frustrating him) and was consistently abrupt and cold though our interaction. He did help by lifting bags onto weigh and to press buttons to get the tickets issued, but I would have a much better experience of United if he has shown any sign of warmth or even smiled. I was struggling with a baby in a carrier, and several suitcase, and he didn't show any sign of humanity. The guy who labeled our bags was a bit nicer. The team overal though just barked instructions at the customers, never looked them in the eyes, and seemed to all hate their jobs. We got our boarding passes issues successfully, yes, but I felt on pins and needles like I had to be very careful not to offend anyone.... Which I don't think is what you want your passengers to feel at the start of a flight."

Pros: "Nothing!"
Cons: "My first time flying through United and I am dissapointed my flight was delayed over 6 hours and we get no refund for that? Really United? Aren't you suppose to be a top airline for a reason. Never again"
