"We love the service … We wouldn’t change nothing …"

"The a330-900neo is an aircraft worth trying out. Comfort plus is premium select, despite the nice features, the backpack doesn’t fit well under the seat. The service to honolulu only gives snacks so make sure to eat a meal before flying the 5.5 hour flight."

"As with the outbound flight, this return flight was not full - maybe 40-50%. As they started boarding they announced they located a few people the help with 'load a balance' of the aircraft. What they had done was to compress all passengers in the middle of the plane leaving no space between anyone. It is difficult to understand why everyone is required to wear Masks, then relocated to remove all space between passengers, when there was ample room to allow everyone to be seated with space between."

Pros: "Excellent"
Cons: "Nothing short"

Pros: "On time, clean and comfortable"

Pros: "Boarding"
Cons: "Food"

Pros: "All of it"
Cons: "Nothing Best flight"

Pros: "Very attentive staff"
Cons: "I have no complaints"

Pros: "Quick boarding process and take off. Flight was slightly late but the staff expedited boarding and take off. Staff is friendly. Service was great. Beverage service was great. Baggage was quickly at baggage claim."
Cons: "Even though its a short flight better food options for First Class would be appreciated."

Cons: "Movie selections, healthy snacks/food"

Pros: "Confort was minor but ok"
Cons: "The flight was not on time. The staff broke my carry-on zip for expansion and refuse to admit it was a suitcase damage which need to be repair. They said put a belt around it to use it !!!! It is a 1 year new piece of luggage from Delsey which is a very good quality brand and expensive!!!!!!"

Cons: "We always board with Sky Priority but the agent took us off the line until Comfort Plus boarded. It was embarrassing to my husband and myself."

Pros: "Good crew, kind and hard working staff. It is so nice to have inflight messaging and that was a pleasant surprise that made the flight go quickly."
Cons: "I found the delta app to be less user friendly than the United one. I wish the in flight entertainment were in the Delta app versus downloading yet another app."

Pros: "Great crew, great entertainment, came in early"

Cons: "After my flight was delayed for over 3 hrs - the counter clerk was rude and unhelpful. She felt it was appropriate for her to flick the customer service phone number in front of my teenage daughters. I would say avoid Delta!"

Pros: "On time departure and smooth landing"
Cons: "More leg room. Stop nickel and dining passengers to appease investors. Delta is an evil corporation"

Cons: "Was a little bit hot"

Pros: "It is a busy travel day and this flight was unbelievably smooth. The entire crew was competent and friendly."

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

Pros: "On time"

Pros: "Great crew and plane arrived on time."
Cons: "No entertainment and no place to charge devices."

Cons: "Paid extra for a seat that didn't have any extra leg room. The entertainment system was broken for the whole plane during the first 2 hours."

Pros: "Although we ended up being stuck on the plane for 2 hours prior to take off due to high volume, weather and as the pilot put it, "possible military activity" the crew kept us informed every step of the way. There was one flight attendant in particular who was so full of energy and made the unfortunate circumstances not so bad. She entertained us and kept us in the loop the entire time as did the pilots. It made the 2 hours not feel so bad which was appreciated."
Cons: "That we were delayed on the plane for two hours on a small plane but I know it was out of their control."

Cons: "Plane was Boarded and we sat for over an hour waiting on fuel. Minimizing the wait time on the plane should be considered prior to boarding. The practice of getting us on the plane to make us wait shhould be stopped. It will creat a much more relaxed and smooth delay if we are allowed to be in the terminal."

Cons: "Seat wouldn't redline."

Pros: "On Time, comfortable seats, good coffee and mixed nuts, smooth flight and landing."

Pros: "The flight crew was friendly and personable. Beverage service was consistent and efficient. Entertainment and free WiFi messaging were great perks."
Cons: "The positives don’t even come close to offsetting the misery of Delta’s seats. I honestly don’t remember the last time I was so cramped and uncomfortable. I’m not an abnormally large man - 6 feet 200 lbs - and there was no room for my legs or my shoulders in an “upgraded economy” seat. I fly weekly for work on another major airline, and only took this one in a crunch. But I am quite certain this was my last Delta flight and I’ll be advising others similarly. The service and entertainment aren’t sufficient to mask an awful seat configuration."

Pros: "Flight crew was excellent"
Cons: "Didn't serve snacks with peanuts because someone one board had a peanut allergy"

Pros: "The crew"
Cons: "The delay"

Pros: "Wi-Fi on the plane is a nice touch."
Cons: "The seats are packed so tight there's almost no leg room - actually there is no leg room when the person in front of me reclined their seat. Since we were advised to get there 3 hours in advance only to wait two and a half hours in what is quite possibly the most uncomfortable waiting room anywhere this just makes the cramped plane even more frustrating."

Pros: "Flight less than 2/3 full, lots of room for comfort. On time, no need to gate check carry on."
Cons: "nothing, it was great."

Pros: "Short flight so no food, drink or entertainment."

Cons: "Flights on time"

Pros: "The seats"
Cons: "We purchased tickets together and our seats were not together when we checked in. We had one small roller bag for the two of us and we ended up having to gate check it along with 3 other people and then there was clearly enough room for it once we were boarded."

Pros: "Compared to previous flight - this was so much better with upgrade to first class and extra space."

Pros: "More seat room than expected for economy tickets. Good service, on time, polite staff"
Cons: "Duty free purchases not waiting for us at boarding like usual. Audio selection on entertainment was v poor"

Pros: "We had terrible turbulence for probably 4 of the nearly 5 hour flight. The turbulence were the Pitts, but the plane, amenities, staff and amenities were top nothcj! Highly recommende Delta."
Cons: "Bad turbulence"

Pros: "Loved the safety presentation made by the live stewardess!!"

Pros: "Able to download boarding pass into apple wallet"
Cons: "Flight was almost an hour late departing, bag is a carry on but storage too small to keep bag, then wifi didn't work the entire flight. Had to run to our connection since our layover time was taken up in Boise. If we had missed the flight, we would have been re-routed to another airport over 1 1/2 hrs away since ours closes. Next flight was not much better, oh and wifi did I t work on it also - last 3-4 delta flights I've taken have been late and didn't have working wifi - starting to think their system doesn't work at all - seriously going to take any other carrier but Delta going forward"

Cons: "Was required to gate check my luggage through to baggage claim."

Pros: "The plane got me & my family safely to our destinations. Easy & fast check-in."
Cons: "Flight delays on both departing & return flights to Los Angeles. Delta didn't offer any compensation for the delays. Crew was not very friendly especially on my return flight. The flight attendant couldn't even give me a bag of peanuts."

Pros: "The courtesy of the staff and the seats in the "delta comfort" section."
Cons: "Too many interruptions. i'm not sure if there is a way but there should be a way to only serve only those who are requesting service."

Cons: "TSA in Atlanta was a nightmare. Really just a little kindness would go a long way."

Pros: "Clean plane, friendly crew. Ahead of schedule arrival, pilots did beat to keep in smooth air."
Cons: "Took a bit to get first beverage. Thy ran out of KIND granola bars before reaching the back of the plane."

Cons: "Flight was delayed indefinitely. Delta supposedly booked me on united flight but made an error."

Pros: "On time Clean airplane Smooth ride Friendly staff"
Cons: "Nothing"

Pros: "stewardess was exceptionally pleasant."

Pros: "Lovely crew"

Cons: "Dirty windows. Could not see out window. I have a photo if requested. I am 6'4" the plane was small cramped and uncomfortable."

Cons: "25 minutes late due to having to wait for galley to be stocked. Left the ramp and sat another 15 minutes on the tarmac. Never happened to me on Delta."

Pros: "Safe trip. Kept informed of short delay. Thank you."
Cons: "NA"

Cons: "The bathroom on the flight from Denver to Santa Barbara was the WORST EVER! I doubt it has ever been cleaned and the poor people that had seats near or at the rear of the plane should have been refunded their money having been subjected to the smell of an “indoor outhouse!” Shameful!!"

Pros: "Nothing, absolutely horrible. This is why I fly Southwest and Alaska Airlines as much as possible."
Cons: "Everything. Mechanical delay missed connection, arrived at gate to see plane being pushed off due to delay. They couldn't have waited 5 minutes? Multiple people missed their connecting flights within minutes. They kept us on the plane in Boise then deplaned and re-boarded. No coffee on flight."

Pros: "Poor customer service and not understanding."
Cons: "Don’t now it’s not the company’s fault it’s just the representative that I spoke to. I don’t know how many times I could explain my situation, and my English is not poor and I thought I was explaining myself clearly. Best think I could do is just say forget it I’ll take my $ 430 dollar last."

Cons: "T"

Cons: "More leg room"

Cons: "Nothing, overall great experience"

Pros: "It didn’t happen."
Cons: "Because of the late plane and possible missed connection, I was re-booked for the next day without any compensation."

Pros: "I travel a lot. All was fairly normal."
Cons: "Entertainment didn’t work. Woman next to me sat cross legged and the bottom of her foot as resting on me. When I politely asked that she not out the bottom of her dirt against me she swore at me and was confrontational and crazy. Flight attendants did nothing"

Pros: "Glad they had a direct flight."
Cons: "The seats didn't offer much room."

Pros: "Very pleasant attentive crew and ground staff. An aborted takeoff on tarmac meant a return to the departure gate and the plane taken to maintenance. The ground staff were superb in dealing with a full plane load of passengers many of whom had onward connections. This meant we had to stay overnight and fly first thing the next morning. Full marks to United for dealing with a potentially dangerous situation and then assisting everyone back in the terminal."

Pros: "I found the reason for being late to be questionable They said heavy snow but as i flew in i looked out the window and saw all roads nicely cleared That does not happen in 3 hours"
Cons: "They did not get my liggage to the connecting flight And here i am in Ukraine with no winter clothes at 7 below 3 days later"

Cons: "Flight delayed in Chicago with no one at gate ro provide any information on when flight would actually leave. Plane was scheduled to leave at 8:40pm and finally left at 12:43 am. Will never fly United through Chicago again."

Pros: "Pleasant flight w pleasant attendant."
Cons: "Tight tight seating! Yuck."

Pros: "Newark Airport is great and the flight was comfortable"

Pros: "Friendly crew."
Cons: "Had a mechanical issue we were told didn't need fixed to fly the plane. Took 1 hour and 20 minutes to complete safety checklist so we could take off. We missed our connecting flight to Cancun."

Pros: "Helpful finding next flight worried can my son it UN traveled and is in a standby I pray he gets on this flight I am really worried. If he does he will arrive at 11:45 pm if not .... I have no clue he is so young and scARED TRACING ACROSS THE Whole country. For mistakes beyond his control saying prayers."
Cons: "I was tied to go tailgate 10 like my paper said they switched flights to gate 15 missed flight had to wait 7 extra hours flying Into Chicago and have a priority stand by pass from Chicago to Knoxville. I need to be on this flight so bad. If I dont make it i have no clue what i will Do. I need to keep my stress down and just prY i get on this flight which would have me i. Knox about 11:30 pm if not i have no clue what to do.the United Team we have talked to have been nice they just can't confirm my Chigaco flight to Knoxvile and i have 31 min. Once plane lands to get to other boarder term and Al."

Cons: "Flight was delayed. Super small aircraft so suitcases didn't fit. Didn't have food options, just pretzels."

Pros: "Flight attendants were very nice"
Cons: "The overhead a.c. spout didn't work. Plane was very hot."

Pros: "The flight attendant was nice."
Cons: "The boarding process was a nightmare there were 4 flights boarding at the same time from gate 57-61. People were coming in line from every direction and it took forever to walk a few feet to get my boarding pass scanned. Then about 1hr into flight it's was freezing in the front of the plane, I was in row 5 and the only solution given to several of those who inquired about it was to "take a walk to the back, it's warmer back there". We were dressed for the winter up front and people in the back were comfortable. It was ridiculous. Mind you this was a tiny plane 1 seat on the right and 2 on the left so not a lot of room to stand and move around."

Pros: "It was a good flight, short but good."

Pros: "More fights to choose"
Cons: "Could not choose the seat at the time booking"

Pros: "That we got to Little Rock early"
Cons: "I had ordered ginger rail and the lady brought me a Diet Coke I told her I don't like Diet Coke because I don't drink Coke and she said I thought that's what you want it now you have to hold onto it until they come back and pick up the trash and she never brought me the ginger rail to drink she walked away and I never drank nothing on the flight back to Little Rock that lady was so rude"

Cons: "Food, like all airlines, is so lacking even though airlines are making record profits while lessening service (crowded, fewer flights, baggage fees, etc)."

Pros: "Nothing"
Cons: "That a bunch of travelers including myself missed our connecting flight in Chicago after united chamged our arrival gate but didn't have any crew to man the jet way. We sat for 20 mins right in front of our gate. From 1 pm to 10 on my flight to Asheville from Chicago was delayed many many times waiting for our airplane to arrive. Upsetting that we missed our connection due to United's poor planning, they didn't hold our connecting flight for us but we had to wait all night for other flights."

Pros: "It was so smooth.No long lines ,no delays,a straight thru flight.And on Christmas Eve morning."

Pros: "The travel agent, Tim, in STL worked very hard to get us on a flight."
Cons: "After a cancelled flight, two delays and lost luggage (that we did not receive for two days after arrival) on the way to Boise, we've now been cancelled on the way home to St. Louis. The first cancellation was due to weather. The two delays were due to late crew and refueling issues. Today's cancellation was due to maintenance. Embarassing. I travel often and can guarantee I will never fly United again."

Pros: "Very smooth and easy. Thank you"

Pros: "Fast and smooth"

Pros: "we left right on time. It was a smooth flight and a nice aircraft. did not use entertainment so no comment there but was a good experience overall."

Cons: "aborted takeoff due to mechanical problem, a bit scary but crew opted for safety and we changed to another plane;thus, long delay but unavoidable."

Cons: "I went on this trip as an veterinary humanitarian out reach. I was also guardian to one high school student so that she might have an experience of such to guild her future. Her flight was missed booked to leave after mine, I attempted to rebook my flight with Luthansia but they would not let me me even partial rebook. I attempted a number of times to rebook the flight but their solution was extreme financial gain for them when more reasonable alternative could have been arranged. They canceled my entire return flight and left me stranded. I had to piece together a return flight on a shoe string budget. Thankfully American Airlines was understanding for it appears Luthansia and United are not."

Cons: "Ok"

Cons: "The flight attendants were disrespectful to not only me but to other passengers. They were not attentive! The plane was dirty."

Pros: "That the plane arrived on time, which is a miracle in itself."
Cons: "No offer by the Flight Attendant to any passenger if they wanted extra snacks or if they desired to have the entire can of soft drink they requested. Only one A/C was operational, so thank God we cruising at altitude cooled the cabin down."

Pros: "Crew"
Cons: "I think that after first class they should load the plane from the last seat forward for ease of getting to the back seats"

Pros: "prompt emails and text messages with the back up plan"
Cons: "Missed connecting flight because flight delayed takeoff from home due to SFO problems. Sat on tarmac for an hour or more, finally took off but missed connecting flight mid afternoon and no other acceptable flights until 11 pm getting into Fort Lauderdale at 730 am. (originally was supposed to be getting to Fort Lauderdale at 10 pm). Also, the aisle seats on the plane had a narrower underseat space that my little boxy carryon wouldn't fit into--and it usually fits under any underseat storage...Luckily the passenger in the middle was willing to swap places."

Cons: "Worst ever Can you credit my credit card for a full refund"

Pros: "Flight to Austin was just fine."
Cons: "My flight back to bosie from San Francisco they changed the gate I didn't hear the change and missed my flight. I didn't get back to bosie until the next day."

Pros: "Nothing"
Cons: "United are the most rudest phone people on the phone to deal with and if it's there fault they never want to comp u last time I fly with united"

Pros: "Flight was on time"
Cons: "That u load the plane assistance backard,loading goes much faster if you start @the back of the plane,& myself I carry only a shoulder bag only ,all the time. U put me @ the back of the plane 90% of the time which means I have to wait for the people that are moving their whole house,making me miss my schedule, I have to spend night @ airport for next schedule."

Cons: "The only complaint is to have to pay for the TV. I feel it should be part of the service. On the way going to Punta Cana the flight attendant gave it to us for free and that was very nice as it made the trip seem to go by faster. Other then that everything was wonderful."

Pros: "Once we got on board the flight attendant was very nice and accommodating. The flight itself was fine."
Cons: "We had to wait 4 hours to board our flight. The plane was late, then they had to replace the whole navigation system. Then at the last minute told us to go to another gate and when we got there we were told to go back to the original gate. Getting another plane from the get go would have eliminated a lot of the hassle we all experienced."

Cons: "no inflight entertainment."

Pros: "The flight attendants were very awesome, fun and professional, and super friendly.... My only negative was this plane didn't offer wifi... If there is going to be an extra charge for the WiFi through United Airlines, then EVERY plane should offer it. Otherwise their should not be a charge."

Pros: "Not only do I get the best price. The fact that you told me what carousel to get my bag from was new to me. I alway check kyak first but now I love u guys. I know my travel site and its kayak"

Pros: "Not a single thing!"
Cons: "I almost missed my flight, because at check in they were only helping Premier passengers. Forced to wait for 45 minutes. All I wanted to do was check a bag! When I finally got to the counter, the customer service agent was extremely rude, slow and frustrated. I had to run from check in to security and only made it to the plane with seconds to go."

Pros: "Free entertainment on mobile devices"
Cons: "TSA pre check did not register from website, had to use standard security line. No boarding or seating preference for military."

Pros: "Space"
Cons: "Heat"
