Pros: "Arrived in PDX 15-20 minutes early."
Cons: "Social distancing on the seats"

Pros: "Everything"
Cons: "Nothing"

Pros: "The crew was awesome! The steward was engaging and made us all laugh and feel comfortable for a short flight when he didn’t have to. He had a great sense of humor and gave the kids cookies and wings. Something I haven’t seen in many years. He and the pilots were great!"
Cons: "Nothing."

Pros: "Good flight"

Pros: "On this short flight, the flight attendant was wonderful, accommodating special requests and being fully engaged with passengers. On time departure, early arrival, overall a nice quick flight to Duluth."
Cons: "CRJ200 planes are always a bit cramped, and having to gate check anything bigger than a small purse is an inconvenience. Hopefully the fleet will change over to the Embrair planes soon. Beware 'Basic' flyers (cheap tickets): you are not eligible to take an earlier flight even if available."

Pros: "The crew was amazing! They were helpful and professional. Made the flight wonderful. Our stewardess, Brenda Joyce, has great energy. My daughters and I were taking a trip to honor my husband who recently passed and she was phenomenal at keeping our spirits up."
Cons: "Better snacks."

Cons: "More leg room and seat width. I don’t like having other passengers pressed against me."

Cons: "I really like more legs room and comfort and crew member were very good and helpful. Regarding food I say it’s just ok."

Pros: "Lots of movies to choose from."
Cons: "Delays out of MCI and late arrival, no hope for a decent seat on HNL leg, couldn't sit with husband, huge smelly seat mate, used up 10,000 miles on my account and paid higher price than current ticket price, middle seats, not happy"

Pros: "WiFi and Entertainment"

Pros: "Leaving early and getting home early. Flight was perfect."
Cons: "N/a"

Pros: "We got on we took off and arrived on schedule just as it should be."
Cons: "N/A"

Cons: "At least one hour late"

Pros: "I liked the cookies and juice. The interactive screen to watch something. The cleanliness. The price. On time. The service. Thank you. The excitement of flying."

Pros: "Equipment felt a bit dated. No entertainment system, which was fine with me. Skipped the offered snack. Just had water. Flight was onntime."

Pros: "On time. Pleasant crew although one was a little green. Short flight. Good communication."
Cons: "Squished into a seat that I paid extra for more room. Yes I had more leg room, but my legs were pressed Up against the person next to me. And for the extra money I paid, the snacks could be a little more substantial. And only a small glass of soda. Really, if this was Delta comfort What were the cheap seats like?"

Pros: "The crew at the airport was very courteous and helpful."
Cons: "No food; not even offered water; I asked a Delta employee about our seats and she was very unprofessional (mind you I'm traveling with kids and my boarding pass said that seats were to be assigned at the gate)."

Pros: "I can’t make it in mexico city on tuesday, wednesday’s performance had to be cancelled and we need to pay the cancellation fee 11500 mexican pesos, please reimburse on the credit card"
Cons: "I can’t make it in mexico city on tuesday, wednesday’s performance had to be cancelled and we need to pay the cancellation fee 11500 mexican pesos of the studio and musicians"

Pros: "Everyone who has a kid knows how challenging certain things can be in a flight and for me the combination of a night flight interrupting my baby’sschedule + a full flight it equalized disaster. My daughter could not get comfortable for the love of life and I just felt horrible and frustrated and what sucked most was the 9 year old and her obese father siting in our row that kept giving us weird looks."
Cons: "There’s NO room in planes between seats. It’s 2018 and new planes must be done ASAP to accommodate people better. I’m 5’1” and 110 lbs but adding my 25lb daughter siting in my lap before she turns 2 is absurd to expect that it will be comfortable whatsoever for us or the people breathing next to us. Please DELTA, lead by example and make sure your planes are designed with more room in between and around the seats. In my opinion, every seat should be first class."

Pros: "Great crew on board!"

Pros: "This was probably the best flight I’ve ever been on. The staff had a great sense of humor, as well as openly honored our military by bumping up an active member to first class."

Pros: "The snack variety"
Cons: "My headphone jack was broken :("

Cons: "The crew was late so we were delayed two hours. I find that extremely infuriating when you are a passenger and have to show up two hours before your flight. I also would lose my job if I was two hours late for a client."

Pros: "On time with no drama"

Pros: "Nice crew"
Cons: "Normal too squished conditions."

Pros: "The crew was nice and friendly and the plane was half empty."
Cons: "When are the Airlines going to start serving a decent coffee on board? It does not matter Delta is now serving Starbucks. Something they do that messes up the whole thing, probably overheat for too long."

Cons: "If flight is full all the time get a bigger plane"

Pros: "Left on time, plane was clean and arrived early"

Pros: "Boarding was efficient"
Cons: "My luggage didn't arrive with me"

Cons: "Due to weather patterns, we sat on the runway for 3 hours waiting to take off. There was approx. 50+ planes ahead of us. I know this because I was sitting next to an off-duty pilot on his way home. About 2 hours in, there was 30 planes left to take off, and then us. They air traffic control people were only letting off one plane per minute which is what was holding us. THEN after the 3 hours on the runway, our crew timed out and the brought us back to gate saying we were not taking off. At the gate, they informed us the flight was not 'cancelled' but 'delayed' to the following morning. I/m not sure how a 16 hour difference is considered 'delayed', but I digress. All Delta reps had NO idea the time of the new flight the following morning and told us all to just 'keep checking the app'. Now, fortunately for me I live in Brooklyn and could just go home. But what about everyone who was at LGA as a layover? I heard from multiple passengers they had to spend the night in a hotel, that Delta did not pay for. We finally got notice the new flight was scheduled for 9:30AM, which they AGAIN delayed until 11:30AM. Many people did not get the second change, and were already at LGA for the 9:30AM flight. To say Delta's handling of this was poor is an understatement. We knew when we got on that plane the crew was going to time out. Again, I was sitting next to an off-duty pilot who told me to 'get comfy, we're gonna be here awhile' the minute I sat down. Delta should have given us a fresh crew, or had a backup one prepared. I understand the weather is out of there control, and I understand you can't have a tired crew piloting an airplane, but there are other ways to have us take off remotely on schedule."

Pros: "They did fly.... finally"
Cons: "Missed connection to Bangor. Had to overnight in NYC. Substituted smaller plane for this transcontinental flight."

Pros: "The moviea"
Cons: "The time of night"

Pros: "The time traveled to get to my destination! It would not be my choice if I was to fly again."
Cons: "The customer service. The flight attendants needs to take some more training on how to provide a better service to paying customers. The seemed a bit unfriendly!"

Cons: "The quality of customer service and efficiency was lacking at the check in counter. Wrong information was given to many passengers as far as checking in baggage and being sent to several line ques for the agent to tell me in the end that I was told the information incorrectly since the beginning. I therefore was unable to board my flight on time, got switched to a new flight and the new flight was delayed for 3.5 hours."

Pros: "Hard to like anything with this delay -- missed 3 appointments in Raleigh."

Pros: "Daughter's first flight and the crew really made it a special experience for her."

Pros: "The crew were very friendly; the power of a smile is underestimated by many, not this crew. Wonderful smiles and service to match."

Pros: "Smooth flight."
Cons: "N/a"

Pros: "Left reasonably on time, arrived a bit early, able to find overhead storage for my roll-on, even boarding in Zone 3"
Cons: "Very tightly packed; minimal comfort for the flight."

Cons: "Although weather played a part in the poor experience, it wasn't the only factor. Delta was unprepared."

Pros: "Flight was cancelled and could not be rescheduled until the 17th causing me to loose 10 days of pay at work costing me 4700usd."

Pros: "The crew was nice"
Cons: "I didn't like the fact that I didn't get my luggage with me when I arrived to casablanca as I lived 4 hours away from the casablanca. I have to come back the next day to get my luggage. I was very mad about it.plus I noticed one of my luggage has been damaged so now I have to buy another one because I can t use it. It was disgusting."

Cons: "There was no food or entertainment on this flight. But then I didn't expect any food, drinks or entertainment"

Pros: "The flight crew was nice and polite. They served drinks and snacks in a timely manner while on the flight."
Cons: "Flight was scheduled to leave early, the plane arrived, but they couldn't turn the plane around fast enough. We left the gat late, then pilot said we would still be arriving half an hour early. We arrived about 45 minutes late, and that was a problem because our connecting flight was due to depart now in 15 minutes. Lightning forced the airport to shutdown, which was great, we had a chance to catch our flight, but we were stuck in the airplane, and we couldn't get to our gate until the all-clear. I know this is not Delta's fault, but they did arrive quite late on a flight that, according to them, would be early. They also never communicated to the other flight that there were several passengers catching that connection. So by the time we had ran to catch our connection they had closed the ramp. Lightning hit again, and they shutdown the airport once again, so the airplane was still at the gate for about an hour, and they did not allow the 20+ passengers to board that plane, which was right there. So frustrating. The only thing that saved it was that our new flight was the new airbus, and although it left an hour and a half later, the comfort level was phenomenal."

Pros: "Stewards"

Pros: "On the flight I got on the 8:20 to Reagan the flight attendances were wonderful! Defiantly made up for me having a aweful time on the 7:20 flight. I loved your flight attendants on this flight!"
Cons: "So I arrived in Atl was on standby for the 7:20 flight to Dca airport I had already paid $50 for standby! I got cleared for this flight and bumped to delta comfort. I was super excited to finally get upgraded! Then the plane had problems we were then again delayed and had to deplane. We were told this would be a 2 hour delay. I proceeded to try an get on the next flight at 8:20 while asking about a window seat the lady told me I would have to pay an additional $19! Well I had already paid $50. So the nice lady put me on that flight after I had already asked for window seat. She put me in the middle seat! I get that planes have problems and flights are delayed! There was so much bad yesterday then good and I feel like delta should know. It's more and more bad everytime I fly! Please fix these problems!"

Pros: "Appreciate having movies available through wifi however didn't realize this until only an hour left in flight."

Pros: "My flight was on time and I was constantly notified what was going on with my flight"
Cons: "There's not much to do on the flight but oh well"

Cons: "Flight was an hour late getting into Raleigh, so an hour late leaving Raleigh for MSP. That gave barely enough time to hurry straight to the gate for the MSP to MSO flight."

Cons: "Being lied to and saying it was weather related instead of the truth of it was a mechanical issue so United didn’t have to pay for hotel!!!"

Pros: "Fast loading/unloading."
Cons: "No drinks. No entertainment."

Cons: "Big man in a small plane is uncomfortable. Add in a second big man as a seatmate and its even more uncomfortable"

Pros: "Very friendly, efficient staff"
Cons: "Plane was late to airport. Then there was a huge rush to get us boarded and it was very stressful if we were going to fly or not"

Pros: "All services where very good from check in to arrival In L.A."
Cons: "There wasn't anything I didn't like."

Pros: "The older planes of United Airlines could use some remodeling. The entertainment system with controls in the middle of the arm rest where the elbow rests is such a bad idea, didn't even bother with this crappy unintuitive system. It was annoying and flashy with bright advertisements or something popping up on a night time flight just sooooooo annoying, turning it off was not intuitive and had to ask the flight attendants how to turn it off during their very busy work of handing out packages with five miniature pretzels and drinks to the passengers, was happy to get a whole cab of juice to myself though."

Pros: "Polite crew"
Cons: "Food."

Pros: "People were polite."
Cons: "I got my flight switched earlier. Paid $57 for it. Then this flight got delayed almost 2 hours so I ended up in NYC at the same time and it threw off my whole work day."

Cons: "Comfort, service.., terrible'"

Pros: "The flight was smooth"
Cons: "The seats felt stiff"

Cons: "Again, seats are too close front to back."

Cons: "Tight seating for transatlantic flight. More importantly avoid Toronto at all costs. Need to clear customs and go back through security again on a connecting flight. Takes forever. Food was not good at all."

Cons: "Explained above"

Cons: "Boarding by zones causes passengers to have to stand longer while waiting to board, inconveniences them by having passengers seated in window and middle seats often arrive after the passenger in the aisle seat, and slows down the entire process because passengers settling into the front part of the plane frequently board and stow luggage while those seated in the back queue up behind them. Compared to boarding by row, the entire process is now one lengthy mess."

Cons: "How they canceled one of my flights just as I landed at my layover for that flight when I look back at Boston they had a direct flight ready for my destination. Very poor management I was stuck in Chicago with no money or food for hours then after they start boarding for my new flight they tell me that I may not be able to get on even with ticket in hand. It was a joke and very stressful"

Pros: "The gate at the Chicago airport was well designed. There was a line for each boarding group, and you could line up early. This is particularly effective for some Asian flights, which can sometimes be chaotic with many different nationalities all lining up."

Pros: "I broke my arm and all of the gate agents were wonderful trying and succeeding in getting me A seats for my comfort."

Pros: "Entertainment options"
Cons: "United chamged our arrival gate without a crew to man the jet way. So we sat for 20 mins this missing our connection flight."

Pros: "Good selection of entertainment."

Pros: "Flight from Calgary to Chicago was excellent!"

Pros: "Connecting flights in China need more of a layover I missed my connecting flight not happy it was a disaster going through immigration takes forever in Shanghai .."

Cons: "Delay and then having to change gates - at O"Hare that means walking and walking some more !! After being insulted during check in. The RUDE woman (poor English) with assisted boarding then the RUDE man that changed my name and my luggage he chose to send to Dayton OH -never been there in my life and he "dug" thru my luggage - as if he was searching for MONEY or GOLD -he pulled out a protein drink and I asked him to hand that to me so I could drink it as I am a diabetic - he shouted at me "I THROW AWAY'. During the two hour delay I could have used it !! Poor service I will fly American from now on !!!!!!!!!!!"

Cons: "While going inside the flight they told me there is no room for Carryon and gave me ticket to book the luggage. When I went inside the Flight there is lot of room to carryon's, why they have to lie this BS."

Pros: "Stuardis"

Pros: "crew was friendly and wonderful - pilots were great."
Cons: "they over-sold my flight and i find that absolutely unacceptable. I know (or i hope) this has nothing to do with Kayak, but it almost completely ruined my trip home to visit my sick father. This industry needs to stop this immediately. It happens far too often, and I know it's no accident."

Cons: "One of the stewardesses had a terrible attitude. She was rude to people and rolling her eyes at them. She also seemed to be rude to her fellow co workers."

Pros: "The crew was awesome and the flight wasn't bad at all"
Cons: "It was suggested that I didn't bring my carry on with me so I left it to be voluntarily checked and it came back ripped"

Pros: "Great boarding at ORD."
Cons: "My seat"

Cons: "The flight was late by 5 hrs due to mechanical problems. The gate crew was confused about what to do and we ended up with several deboardings and boardings. Food was terrible. The entertainment system did not work."

Cons: "8 channels of looped shows and movies. Too long a flight for that...and then have to use my device to watch on the free part of the wifi.so no battery left. For this price? And I booked through Lufthansa but flew United. Bad form."

Pros: "the japanese speaking flight attendant was exellent! she was very observant to passengers needs. i was also pleasantly surprised by the entertainment system."
Cons: "there was a flight delay due to maintenance, which was inconvenient."

Pros: "Nice new plane"
Cons: "2 hour delay due to a name discrepancy on a passenger. Not fair to keep everyone waiting for one person"

Pros: "The vegetable ravioli we had on our flight was top notch and the crew did a great job of making sure everyone was taken care of on the flight"
Cons: "I flew economy, so I knew that I wouldn't be getting a lot of space. But I wasn't prepared for how much less space I would get compared to the other seats on the plane. I was uncomfortable for most of the trip."

Pros: "Very funny and skilled captain. Comfortable seats with lots of leg room"
Cons: "Crabby flight attendant"

Pros: "United offers so many free movies and shows it makes the flight fly by."

Pros: "Glad you didn't give priority to those with other designations like priority plus etc"

Cons: "Plane late leaving Chicago due to no pilot."

Cons: "Long delay for maintenance. Barely made my connection in Munich."

Cons: "I ordered and paid for food that they forgot to serve me. I had to go to the back to ask for my food. When I did they were rude about it. UA has offered a coupon for 50.00 that I can use if I fly with them again-- which would cost about 1000. No thanks, United. I'll fly with China Air."

Pros: "No delays."
Cons: "No complaints."

Pros: "On time arrival, the food, the crew"
Cons: "No power outlet and very old entertainment system. United has introduced a nice wifi-based entertainment system but if you do not have power outlets to keep devices up the system is pretty much useless after one movie or less."

Cons: "Not only did we sit on the plane for over an hour before taking off, but on an over four hour flight I was refused water towards the end. When I asked for more than one glass I was rudely told and I quote, "you know what? No. We have other passengers who may want water." Are you kidding me? I sat down feeling scolded and like I asked for something ridiculous. We landed after 2am and most of the passengers were sleeping and I doubt anyone asked for more water since I didn't see the flight attendant move again. Perhaps she was upset that I interrupted her from reading her paper? Extremely displeased with my experience. I"

Pros: "Great"

Pros: "The last row was really comfortable."
Cons: "The lines set up to let people onto plane were disorganized."

Cons: "The flight was over one hour late departing ORD. We had approximately 15 minutes to make our connection at IAD. While I understand that the delay happened because the copilot was late because of a fender bender, I believe the delay could have been much shorter. Since they had telephone contact with the crew member we could have been boarded before he was on the plane and departed sooner. Also no reasonable explanation was given for the delay other than a crew member was not there."

Pros: "Mechanical problem, changed planes and left 5 hours late. Missed my connection to Taipei. While the airport hotel we were sent to was adequate, it wasted an entire extra day to get there."

Pros: "Can't say I liked anything about this flight or my interaction with United about it."
Cons: "Where do I start - tried not to select a seat until boarding, so I can get a chance at seating up front of the cabin - the online system selected one for me anyway that no one could remove. With 20+ seats open when I left for the airport - in the 20 minutes or so until I got there, they were all taken and I was stuck in a seat in Row 37 in the back of the plane that I didn't even select. The Premier Access line was taking 40 minutes to process and had to be moved to a regular line that took only 10 minutes. Plane was an old 767 with my seat mate overweight and spilling into my seat - since flight was supposedly full , no chance to switch. Flight attendant light wasn't working and had to go to them myself to get headphones that weren't provided. Overall, horrible experience I wouldn't want to relive again."

Cons: "I was informed today that one of my checked bags was picked up by another customer who eventually realized it was not her bag. She brought it back to the airport and refused to turn over the bag until the airport compensated her. (How this happened I have no idea because I stood right by the entrance of the baggage claim and never saw the bag come out). The customer refused to return the bag until the police became involved at which point she agreed to write a note confirmed she did not steal anything. The bag then needs to be sent to me in 2 days and I'll have to verify myself that indeed nothing was taken from the bag. I'm very concerned how this individual came to be in possession of my bag considering, again, I stood right at the entrance of the baggage claim conveyor belt from the time it started to when it ended. As a result, this experience really made me feel frustrated and violated."

Cons: "They knew we were on our way to the connection. They told us to run, we did. We were not aloud on the plane. Caused 10 hours of flight delays and cancelled flights because they could not wait 2 minutes.... Horrible experience."

Pros: "It's hard to understand why the flight attendants cannot be consistently polite when communicating with customers."
Cons: "Sour attitude of one of the flight attendants. The age of attendants doesn't bother me, just when they are jaded and surly, especially on a transPacific flight."
