Cons: "This plane was not appropriate for social distancing, I would not have booked this flight if I knew we wouldn’t be able to keep a distance from other people."

Pros: "No middle searing."
Cons: "The tv did not work. The temperature was hot the whole flight. No airflow."

Pros: "The crew was very kind."
Cons: "Th plain boarding took much longer, we flew in circles above JFK, waited for a gate for us, then waited for all passengers with connecting flights to get off because we were late and that resulted in a VERY long process for the rest of us. The descent into the airport was also not the smoothest, but it was a smaller plane."

Cons: "Seats could have been more comfortable. No space. Food made me sick."

Pros: "Seating and serving, both very good"
Cons: "I couln't get my view on for movies, since there was (I presume) a charge for the earphones. Won't know now what happened to Jean Grey. Maybe offer a small book cart as an alternative entertainment for us cheapskates? do-de-do..."

Pros: "Quick flight"
Cons: "Organization of entry gates. Sat in the plane for about 30 min after landing."

Cons: "My wife and I couldn't sit together regarless of how much money we wished to spend on reserving seats."

Cons: "The check process was ridiculous. There not enough room in the box for me to explain my experience but the ticket agent lied to me, said he couldn't take my bag until I got a paper receipt and boarding pass from a kiosk despite having had pre-paid for my bag and digital boarding pass. 25 mins wasted"

Pros: "Crew very nice."
Cons: "Better food"

Pros: "Boarding was efficient. came through often for water, coffee etc"
Cons: "Rotten attitude of most flight attendants (especially boarding door attendant for ATL-LAX portion and first class attendant for LAX-OGG portion). Some of the worst I've experienced in a while."

Cons: "Late and bumpy"

Cons: "I’m tired of Delta gate agents “requiring” those in Main cabin 3 gate checking bags!! Both legs of the trip it came to a point they said it’s mandatory to gate check all remaining bags. We get on board and there’s plenty of overhead space. Even a flight attendant mentioned how empty the bins were!"

Cons: "Flight was 1,5 hr delayed, which almost caused me to miss my connecting flight"

Pros: "Nothing. Delta cancelled the flight with no explanation, and ruined our last day in Omaha."
Cons: "An explanation as to why the flight was cancelled, as well as help with finding alternative accommodation. We had to fly back very early via Atlanta, and spent the day in transit, which forced us to cancel a reservation in Omaha and erased our ability to enjoy the final day of activities there."

Pros: "Crew had pleasant personalities.. not stoic annoyed faces"
Cons: "People should wait their turn getting off the planes “Wait until the seat in front of you is empty,” says the elementary school teacher .."

Cons: "My flight from Chicago was two hours late and that's why I missed the flight from Atlanta to Buenos Aires. No one helped and did not know that the flight was delayed and I had to find a place to sleep. I'm not satisfied with the experience and I have not yet arrived in Argentina because of the whole"

Cons: "On my opinion Delta is one of the best airlines. Staff are friendly and they made me feel service. They are really nice and they.take care of been on time and anything you ask them they are there to answer. Great airline"

Pros: "The flight was solid and they provided a consistent experience"
Cons: "Not applicable"

Cons: "... on top of that I kindly requested to speak with a supervisor and i was denied it. As a customer I deserved that. I would a ticket with Aerolineas and nowhere it said it was delta. I followed the baggage allowance explained on kayak website and on Aerolineas Argentinas. I took a bicycle which is free and i pay $100 to packed it as Aerolineas wanted. When I arrived it was a Delta flight and they told they don't allow bicycles and that i had to play $150. Aerolineas website and kayak clearly says that bicycles were free on my flight. I show the agent my ticket and that no where it said delta to consider what he was saying since it is an alliance but i was not informed about it. He said no and after wait there for a while before boarding i kindly ask to speak with a supervisor and the denied it and disappeared. I request a refund of my fee to you for providing incorrect information."

Cons: "Nothing negative to say!"

Pros: "Crew was very good I would say that 5"
Cons: "This Delta flight did not have seat back screens to watch in flight entertainment. You needed to use your smartphone or tablet keeping in mind Amazon tablets won’t work. You needed to go to delta website and choose what want to watch the you needed to have Gogo Flight entertainment app already on smartphone and then would work. Not easy even for me a vivid user of tablets and smartphones. The seats had miniumal room available between seats it felt like I am on 5’qq so couldn’t imagine anyone taller that comfortable unless get first class. I even upgraded for “comfort” section which gave you a few inches extra. And wdith of chair me being a 36 waist was a little squeezed in. Crew was very good tho I will say that. But I laways fly JetBlue or Virgin America, or Alaskan Air for reason of more comfort and lower prices ticket but this time on flight close to my destination was Delta which I Flew for free, I would much rather buy ticket on the three others I fly if could have."

Cons: "The food was awful if you didn't like curry or cheese (my husband and son didn't eat and it was a 9 hour flight). The landing was aborted after the wheels were on the ground. We came down way too fast and hard, and had to take off again and ascend very quickly. Circled an additional 25 mins before landing again."

Cons: "Very delayed"

Pros: "My trip started off with airplane problems from the beginning. From my flight being delayed multiple times by air china to the overly packed united to the confusion of the non updated confirmation numbers or the e-ticket number. Even on the day I left upon arriving to the airport my confirmation number they had just given me after all the prior problems still didn't work. Air china had mediocre food with okay entertainment except my headset jack on the TV was broke and I couldn't watch anything. On the last air china flight from Bejing to Bangkok. I couldn't even charge my phone, watch any entertainment and basically was just stuck with no WiFi. Justfly wouldn't compensate for the changes on their end and said I myself would have to ask the airlines for compensation which the.the airlines directed me no where for compensation or even to upgrade my seat. Now I'm finally in Thailand but I'm scared of my return."
Cons: "Everything was really not great. Air china had mediocre food that some of it wasn't bad but other was so so."

Pros: "EXELLENT!!"

Cons: "I didn't go. It was $400 just to change my name on my ticket from my maiden name to my married name. I am so disappointed and will never use Kayak again!!!"

Pros: "The staff was unbelievably rude. NO SNACKS, NO FOOD. I was told I shouldn't "expect" there to be food. Because our ticket was screwed up due to United error, we almost didn't make the flight. One of our 3 seats were given away to another passenger. If someone didn't volunteer to give up their seat, we would not have had 3 seats."

Pros: "Customer service was very helpful"
Cons: "To get an extended flight I instead"

Pros: "It was cheap"
Cons: "Customer attention, they wanted 50.000 lb not a bit above otherwise is US$200!"

Cons: "I don’t like that you have to purchase WiFi and movies. My first flight was with JetBlue and they provide those things for free. I do not understand why United doesn’t do the same. Overall I was disappointed for the amount of money I spent on the flight and being told I’d have to purchase movies and WiFi"

Pros: "The crew did a great job helping us on board and talking us through changing our connections."
Cons: "The flight into Newark was delayed four hours because the airport was shut down for political officials. This probably should've been expected."

Cons: "Baggage check in was very rude. I handed my boarding pass and passport first and the mouthy black man yelled that my bag should be placed first. I was making sure first that I didn't need to go to a different area for bag check. United needs to teach their workers some manners."
