"Staff was great. Could have had a menu so I could know what I could order in between meals."

Cons: "Great flight. No issues."

Pros: "Flight attendants were friendly."
Cons: "Luggage that had to be checked at the gate was not immediately available when we landed."

Cons: "Breakfast could have been offered."

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."

Cons: "Delayed flight ruined it."

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: "The flight was average, but the quality of travel on Delta this year has been the worst I’ve ever seen. It’s average at best and I’m considering going back to American because I have yet to have a true Delta flight consistent with previous years, the whole reason I switched to Delta."
Cons: "Everything"

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

Pros: "Delta provided great entertainment options and it felt like endless food and drinks. The seats were also a bit more spacious than usual"

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 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: "The flight itself was fine."
Cons: "The flight was delayed and it set off a slew of connection problems."

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: "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."

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."

Cons: "Delta Flight #1661 I paid for 1st class. My first flight was late so I arrived at the gate after boarding began. When the gate attendant scanned my ticket another printed. When he handed me the ticket my seat had changed to seat 25E. I told the attendant that I had paid for first class. He asked me to step aside while he contacted his supervisor, Joe. Then I had to wait until ENTIRE flight had boarded which defeated part of the reason I paid for the upgrade. This was on top of the fact I was so thirsty because 1st flight didn't have drink service and because it was late I had to book it to the connection arriving sweaty, hot and needing to use the bathroom. I was told they had given my seat away to someone as a free upgrade. Joe offered me a $100 voucher to take other seat which was less than I paid for 1st class, plus the seat was a middle seat in the rear of the plane. When I told him as much, he tried to manipulate me by telling me that they would have to kick someone out of my seat. When I declined the downgrade, they made me stand by while they kicked someone out of my seat which was embarrassing and humiliating. Then, when they handed me a new boarding pass, it was not the seat I had paid for and selected, instead it was in the first row, which I’ve always hated because there is no under seat storage and I cannot keep my backpack with me. When I pay for first class, it is primarily so that I can board first and so that I have extra room to work (which I need access to my bag to do). While I was trying to take out the minimum of the things I needed from my bag and figure out how to manage without it, 3 times a flight attendant told me they had to take my bag (since I was the last person to board they tried to prevent me from using the bathroom and they were anxious to leave early). I tried to explain that Delta had prevented me from boarding earlier and that they gave away the seat I paid for which was NOT the first row."

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

Pros: "Crew was amazing."
Cons: "It would have been nice to depart within an hour of my original time."

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

Pros: "WHEN WE LANDED WE ONLY HAD 10 MINS TO CATCH THE NEXT PLANE, WE HAD TO RUN ASAP TOWARDS THE NEXT PLANE AND IT WAS FAR."
Cons: "GIVE BETTER ROUTES TO CUSTOMERS OR POSSIBLY GIVE THEM BETTER TICKETING SCHEDULES"

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

Pros: "Without asking, the crew arranged to have my partner and I sit next to each other. That was such a pleasant touch of service for our trip. Also, the connection was perfectly timed at Chicago flying to Bozeman."

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."

Pros: "Empty plane personal seating everyone"
Cons: "Nothing"

Pros: "ANA was excellent in getting us on an earlier flight-"
Cons: "Unfortunately, they sent us to the "wrong" security checkpoint- at the opposite side of the airport. From the checkin desk, we were told to go to the NORTH security checkpoint. Walking the terminal again from where we came, we passed the SOUTH security checkpoint and made it another 5mins to gate."

Cons: "Delay for 3 hours"

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

Pros: "I liked the extensive entertainment options."
Cons: "I didn’t like that for about 10 hours there is no meal service."

Pros: "Free Wi-Fi, outlet to charge devices, built in phone stand, current movies, & water every 2 hours."
Cons: "8 hours flight only 1 snack and you have to pay for dinner if you want it."

Cons: "The waiting in the lobby."

Pros: "Crew was great, and boarding was a breeze."
Cons: "For the price, there should be better food, and a bit more breathing room."

Pros: "I'm glad the problem was found prior to us leaving the airport."
Cons: "Having to wait almost 2 hours, missing my connecting flight.. causing undue stress prior to vacationing -OVERCROWDED!!! had to sit in a center seat squashed for 3 hours."

Pros: "My father passed away earlier that day and I needed a ticket quickly to fly home. At the airport I was a mess and the airline counter attendant was so amazing helping me ( I had never flown United and had no idea about their luggage policies ect..). She quickly pulled me aside.. helped me with checking in and did her best to fine me another seat thatvwas better than the one I had already chosen.Also, she gave me a hug and her condolences. Flying with an airline that has heart helped me so much during one of the most difficult times of my life. I will absolutely fly with them again."
Cons: "No complaints ... but I paid for a movie to take my mind off of my father's passing during the flight and there was a short in my monitor for our whole row. It kept cutting in and out and "searching for signal", I only was able to see 1/4 of the movie I paid for with all the interruptions in signal."

Cons: "The food options are poor at best and it's really sad that they don't offer anything for free. My ticket wasn't cheap so I can't imagine they're saving me money on my ticket by not offering better food on that long of a flight. Especially lacking in any gluten free options or anything resembling healthy. A small thing of fruit that probably has 70 calories is not enough to sustain someone on a near 8 hour flight."

Pros: "The people were all very nice. The plane was top-notch. Would definitely fly with them again if I had the opportunity."
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."

Cons: "The plane was delayed 5 times causing us to miss our connection. We had to stay overnight in the airport in Chicago. We were told that there would be blankets waiting for us that we could use however there weren't and we had to practically beg for them."

Cons: "The movies kept doing out. They told us to log in and get compensated in a few days"

Pros: "a little bit more foot-room than my previous flight on a different airline."

Pros: "The stroopwaffles were a tasty treat. The flight was well managed and crew was attentive and professional. I never have problems with United and like how pilots keep us informed with when to expect turbulence. The first hour through storms was a bit scary. T.v. on the seats was a good feature but I didn't order anything."
Cons: "I put my phone in the pocket in front of me and when I took it out it was sticky with gum someone put in there. Inevitably crew can't check every pocket and nook for gum or garbage from previous travelers. I don't blame them. We almost were asked to leave the flight bc it was overbooked by 2 seats. Made me a bit nervous when we walked by check-in and they pointed out we were a traveling pair. Lucky there were a few others"

Pros: "Was delayed two over two hours in HNL. When UA decided to transfer all passengers to another plane, it was such a beautiful flight and the Pilot of the plane."
Cons: "I didn't like the idea that we went given a free meal because the plane broke down."

Pros: "Window seat"
Cons: "Same experience on ANOTHER 8 hour flight I have NEVER flown on an international flight and NOT received a complimentary meal or two...When I'm flying for 8 hours. On top of that the seats were very small and uncomfortable. I shouldn't feel a person grabbing a magazine or pulling down a tray when I'm sitting in the seat in front of them. I couldn't consistently watch a show or movie for 3 minutes thanks to the wifi and or app on MY Samsung tablet....it's SO sad that you guys couldn't have them already installed like other airlines. This airline is already in hot water, I expected MUCH better customer service. I will do my best NOT to use them again and tell others to do the same."

Pros: "Flight wasn't full so got to sit w/o middle seat psgr."
Cons: "UA app for in flight movie kept losing contact or sound."

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

Pros: "The crew were polite and helped to assist the passengers who has the same seats."
Cons: "The fact that I had to download an app for onboard entertainment prior o my flight is farcical."

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

Pros: "The flight attendants were friendly and attentive to my needs. I like good service and friendliness so for this experience I give 5 stars"
Cons: "I was uncomfortable in my seat but that's expected on an airplane"

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: "United got me from point A to point B"
Cons: "Crew was rude, not just to me, but to other patrons. Flight was packed going and the man scanning boarding passes spoke to those of us asking simple questions as if we were stupid and defiant. Was he a prison guard in his previous job? On the way to Newark, I had an aisle seat. One of the stewardesses blazed by me with a cart ramming it into my shoulder without so much as a, "sorry." I'm not a big woman but maybe as I dozed off I leaned over a bit...There is no way she didn't feel her cart hit me. Rudeness, it seems is a part of the culture at United because the flight attendants coming back squeezed past the long line for the bathroom without saying, "excuse me." They did however, say, "I need to get by," and one of them brushed by the gentlemen sitting next to me and bumped his laptop and coffee. Overall it seems that the crew working these particular United flights have forgotten that we pay hard earned money to fly. Some of us are going on vacation, to see loved ones, and some are flying to deal with unpleasant circumstances. The staff may fly several times a day, but most passengers do not. There's a lot of prep and anxiety, that goes into taking a flight and a surly flight crew multiplies that anxiety. No one wants to fly with a crew that hates their job."

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: "I'm handicapped and the help getting from terminal to terminal. The people were very helpful."
Cons: "I have metal leg braces. I had to remove them to get in the seat. So the flight was uncomfortable. It would be nice if the plane could have handicapped seating.I know I wouldn't have minded paying a little more for comfortable seating."

Pros: "Pilots and some flight attendants were kind and friendly."
Cons: "On the return home, I was seated in the last row right next to the lavatory. I was bumped into at least 25 times by other passengers and flight attendants. I would suggest removing the aisle seat on both sides."

Pros: "Good food and very friendly stewardesses."

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?""

Pros: "Getting off the plane"
Cons: "Very delayed flight No updates for departure, empty desk until it was time to depart, for why we sat on the runway for so long, no update on landing time or that we were starting descent"

Pros: "Good service"

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: "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."
