Scores according to KAYAK customer reviews

Pros: "Being on time with everything."
Cons: "Really felt happy on time touch down nice journey with delta"
Cons: "It was a Great flight. I always enjoy flying Delta"
Pros: "Friendly crew"
Pros: "The crew was amazing! The seat was comfortable."
Cons: "Used the self check in kiosk to begin! That was awesome! But after that I still had to stand in line to check in my bags. That part of the process took a bit longer than expected."
Pros: "Nothing special"
Cons: "That was the most uncomfortable and cramped seat I had ever had on a plane flight. Even sitting on the pillow did not help."
Pros: "I like that I arrived at my destination safely."
Cons: "My allergies were bothering me due to the airlines allowing animals to travel as passengers, in this case a rabbit. I am very allergic to animals. My breathing was compromised."
Pros: "This had one of the best attendants I have encountered. She was extra friendly and made us feel good."
Cons: "Plane was way too hot and stuffy, wasn't until about 20 min into flight before started to cool down."
Cons: "The flight was 2 hours delayed.. this cause a lot of inconvienece.."
Pros: "Delta personnel at DTW knew they were overwhelmed and did everything they could to mitigate the problems."
Cons: "Delta should have had more than 3 staff on to check in 300 people."
Pros: "The food and the treatment"
Pros: "Flight was on time and arrived a little early."
Cons: "I was seated next to a very large man (6’5” he said) and had no room in my seat. Thankfully the seats in front of us were empty and the flight attendant moved him."
Pros: "Everything was on time and efficient. I also liked that the captain came on and updated us on arrival, turbulence, weather, etc."
Cons: "Ran out of snacks by the time they got to my row"
Cons: "Flight was delayed out of St. Louis causing several of us to miss our connecting flight from Salt Lake City to Portland. Delta was of very little help in assisting us in making a connecting flight. They could have at least helped with travel arrangements and provided us with a little food, a pillow and a blanket as we waited in their terminal for the next flight on their airline which was a several hour wait. I understand these things happen but the passengers didn't cause the problem and Delta needs to take care of people better if they expect to earn repeat business."
Cons: "Ac not working at last 30 minutes of flight."
Cons: "We lost our whole vacation and had to pay for the plans fare twice because My last name was spelled wrong on our tickets and we were unable to use them because my passport didn’t match the name on the ticket. We had to rebook everything pay almost twice as much for the plane fare, our Lodi g cost more and our trip was delayed for two weeks. Vyama is blaming us for spelling our name wrong and claimes that it’s our fault this happened because everything is automated. There saying they don’t touch anything that we enter into the booking but somehow everything they claim we entered is now in all capital letters and the space between our first name and middle name is now gone and all run together. The coustomer service number gets you to someone in India. I have tried to get this addressed four times now at first they tried to place the responsibility on the airlines now us and they have hung up on me twice. Kayak has been worthless, they also just pass the responsibility on to someone else. We will never use them again ant I intend to make sure that this mess is put out in social media to hopefully keep others from having their travel plans ruined by their flawed system."
Cons: "They changed my flight to a different one departing 2 hours earlier and did not notify me! The original flight was still available & they would not let me take it despite my reservation paper work. CRAZY! I have a two hour drive to the airport this gave me the option to leave home at 2:30am or go the night before and pay for a hotel. Flight was managed by DELTA who also did not care! All involved blamed each other. Beware"
Pros: "Movie selection was great!"
Pros: "The flight is short"
Cons: "Delayed from 930pm to 6am. Didn't tell us till almost midnight. Because of scheduling issues not weather or anything. The check in people had no idea what I was talking about when I tried to check in for my 6am rescheduled flight."

Cons: "Seatbelts very short given ample seat size"
Pros: "Everything from the check-in to the landing was great. We were well informed about what was going on with out luggage (we were on a regional flight) and the assortment of free snacks were superb! I guess I'll be a returning customer"
Cons: "I was expecting some form of entertainment (radio, overhead monitor, etc) on the CRJ700. But it really don't take away from the experience since T-Mobile partnered with the Wi-Fi service and I received a free hour of Wi-Fi!"
Pros: "All was quiet. It was an early flight. Nice offer of more snack choices than other airlines."
Cons: "Didn't understand why I had to wait until getting to the gate to have a seat assigned when I purchased tickets several months ago. Since I was in the last boarding group, Had to check in my bag since it was already full, had fragile stuff in there and hoping everything is ok. it is what it is. Not anyone's fault but disappointing to have to do when I didn't plan on checking in and going to pick up at the baggage claim. This is what i wanted to avoid in the first place. could have at least offered to let us pick them up as we deplaned and not baggage claim!"
Pros: "Free earphones"
Cons: "Delayed boarding Delayed flying after boarding Delayed in flight service"
Pros: "Free ear phones"
Cons: "Late boarding Late take off Maintenance after boarding Two hours before refreshments Boring movie Bumpy flight Very hard landing Home an hour late"
Pros: "The one good thing about this unexplained ordeal (the flight was delayed for 5 hours, causing me to miss my connection) was that, after a few hours of hearing nothing (no emails or texts from Delta), I finally saw some options for different flights pop up, so I was able to book a new flight without calling India. Also, I got an exit row seat on my new flight to MSP."
Cons: "They moved our gate about six times and never told us why the flight was delayed. Actually, the biggest annoyance was that Delta told us nothing. The only reason I knew about the delay and gate changes was because of Kayak! I know I am signed up to receive texts and emails from them, but I guess they forgot to notify me."
Cons: "All was well"
Pros: "Great experience"
Pros: "Comfortable flight, ample leg room, and the chairs were pretty plush. Comfort+ is pretty nice"

Pros: "Newer plane! Comfortable"
Cons: "Nothing just great"
Cons: "Not enough water on the flight and we landed in a parking lot and shuttled back to the airport."
Pros: "Flight attendants were competent."
Cons: "Air conditioning was extremely noisy."
Cons: "Flight from LAX to SAN was good once we got across the airport from Westjet terminal to the Delta terminal. LAX is never simple! Comfort on aircraft today is never comfortable unless you pay the extreme pricing of premium seating."
Pros: "Smooth boarding, no delays, quiet easy flight, arrived on time and quick deplaning."
Pros: "I was cleared for standby! Flight attendant at the stl gate is always friendly and willing to help! I love her!"
Cons: "I waited almost 6 hours on the phone the night before the flight to get on standby! Almost didn't get the flight! Was charged $50 only to not get on my next flight because it was over booked! Flight attendant was very rude!"
Pros: "Just absolutely uneventful and quick."
Pros: "I liked that I was able to get able to get an earlier flight!"
Cons: "I don't like that I had to pay $50 extra dollars for standby on both legs of my flight! I am a very loyal delta customer and these past times flying I feel like my favorite airline is turning into the bad airlines delay everytime, problems with the plane fare prices too high! I'm starting to think about taking my business elsewhere!"
Pros: "10 minutes early departure"
Cons: "There isn't enough seats in the gate area and sitting on the runway for 10 extra minutes we could have been early"
Pros: "It was great and very roomy I felt like a movie STAR!!!"
Pros: "Got my first class seat, smooth ride, early arrival"
Pros: "You got us there safely."
Cons: "Not sure who is at fault for running out of de-ice solution, but keeping us sitting on the tarmac without air ventilation for almost 3 hours... with only an apology and a last minute glass of water? that was terrible customer service."
Pros: "Flight did not take place because of cancelled return flight. the whole itinerary was cancelled."

Pros: "We got to our destination safely, and American provided us with extra legroom seats."
Cons: "Service was curt and there was only phone-based entertainment."
Pros: "Spacious aircraft for a relatively short flight. I usually take a smaller aircraft that requires us to check our luggage. I'm reconsidering where I will have layovers now."
Cons: "Flight connections time was not enough for mam with infant.we missed the flight should better set up that kind of big airport"
Pros: "To be fair. The flight is only 50 minutes. By th time you get a drink it's time to land. It is completely unfair to the staff to have to do that. A flight like that. Have a box with a snack and some coolers that have 5 different beverages. I wouldn't even sell booze. I person can hold out for a flight that shot to get one on the connection or in the terminal."
Cons: "It's always a cramped flight. Nothing to be done except use a bigger, more spacious plane. The good thing is it's the fastest way to get to Chicago from where I lived it would take 6hrs by car."
Pros: "Spacious seats"
Pros: "Mostly friendly staff and quick flight time."
Cons: "Only half the plane got snacks and drinks. Additionally, I was forced to check my bag, which is a pretty big deal because I was connecting to an international flight and was unable to retrieve my prescriptions in all the rush to check my bag."
Pros: "I was so happy I could check in online and boarding was a breeze. I actually got to sit by the window when my original seat was in the middle. So nice of the ladies to suggest it to me."
Cons: "No complaints"
Cons: "The video monitor for my seat was broken. So, low entertainment score."
Pros: "everything was on tyime"
Pros: "On time take off"
Pros: "A nonstop flight, with a friendly efficient crew, met my expectations. A crew member went above and beyond when I asked for a coffee stirrer with my coke and ice."
Cons: "I've been spoiled by another airline's access to screens on the back of the headrest. I have my own hand held devices to entertain myself instead."
Cons: "Flight was late, got a message from Kayak that it was delayed 3 hours...thank goodness I happened to check again, because then it was only delayed for 41 mins, then it gave me an update that it was only 21 mins delayed, then went back to 41! Pretty inconvenient, and it would have been nice to get a text, not just some silent pop up"
Pros: "Got to La Guardia almost 26 minutes early but then waited FORTY minutes for the gate!"
Cons: "AA needs better coordination with the horrible La Guardia airport"
Cons: "Delayed a total of four hous!"

Pros: "On time arrival"
Cons: "Everything else"
Cons: "The storage are very small, by the time i boarded everything was full. I had to hand carry bags and i had to put it in front of me which is a very small space already, on top of that i had the window sit so i had no space to move. it was very uncomfortable, and flight was delayed. We sat there for an hour before taking off but i understand its due to the weather but it was my worst plane ride not worth 300dollars. I will not ride american airline again."
Pros: "JAL is customer oriented and it's always a pleasant experience. Unfortunately, though the return trip is also JAL, the cabin crew isn't."
Cons: "Everything was great."
Cons: "Only suggestion would be to make the connection process a little easier. If the passenger doesn't speak English, the fact you need to print the international ticket in Miami, then re-enter at checkpoint might create confusion."
Pros: "The flight attendants were great and very friendly!"
Cons: "The wifi wasn't very good so I couldn't access the in flight entertainment I also had my own snacks so I didn't buy any food"
Pros: "Boarding was good, Good flight , good service , plane was small for the distance with limited space for movement ,"
Cons: "No food or beverages for me. I slept comfortably on my flight"
Pros: "Flights were on time. Airport was clean."
Pros: "I don't know how airlines get away with all the stipulations and regualations they have in the buying process there is. Otho g I like about the scam artist they are"
Cons: "The fact they they can just make it a policy and then because the employees have to have a job and enforce it blows my mind. 200 dollar transfer fee plus the difference in the ticket when it's over two weeks in advance. You people are scam artist"
Pros: "You provide me with the best ticket prices and to me that was the the most important part of of the trip thx"
Cons: "The airlines charging for your luggage"
Pros: "Plenty of leg room no entertainment so I dozed."

Cons: "Not enough sodies and I couldn't smell my own farts."
Pros: "The fact I made the flight"
Cons: "Nearly missing the flight that my luggage did not arrive with me that I had to go back to airport 6 hours later to get it!!!!!"
Pros: "Frankly there isn't much to say here. After 7 flights in 2 weeks there was only 1 flight with great staff that actually cared about the customers and looked like they enjoyed their job. The rest treated guests with indifference at best."
Cons: "Customer service is dreadful, the planes are so old they still have cigarette lighter charges in first (but of course no adapters), no food/snacks of any significance, and they seemingly cancel flights at a whim with basically no staff to help re-book the lines of guests that have been disrupted. I pity those who loose luggage AA baggage services are flooded with lost baggage they just don't care any more. Seriously its embarrassing how little they care about customer service."
Cons: "We were delayed for 4 hours, due to a mechanical issue. We were not given any forms of reimbursement. I would like a 500.00 voucher."
Cons: "Flight was delayed."
Cons: "Would be nice to know ahead of time if flight is equipped with an in seat television so as to be prepared to bring headphones."
Cons: "Cancelled flight, not notified in timely manner. Delayed Five hours due to be placed on connecting flights instead of a direct flight which is what I paid for."
Pros: "We arrived safe."
Cons: "Departure 1.5 hours late. Missed connection. Travel took 16 hours instead of 6 hours."
Pros: "All great."
Cons: "Flight delayed about two hours"
Cons: "Flite was late."
Pros: "Everything was timely."
Cons: "No complaints"
Pros: "I was very pleased that the attendant gave me a free drink since I had a military ID. It was very kind of her."
Cons: "The flight was delayed multiple times. We were never informed as to why this was. It was very frustrating since I had a connecting flight into Tucson from Dallas. I got off the plane with twenty minutes to get to my next flight which was not in the same terminal. The plane was also incredibly hot while we waited to take off, I was beginning to become uneasy and nauseous."
Cons: "The flight was cancelled, which was not resolved by the airline."
Pros: "Zero of it"
Cons: "The fact they cancelled this flight for no reason, didn't contact me at all even though they had all of my information and than barely tried to re book me. They wanted me to take 3 connecting the flights the next day. And the next flight I was able to get on 24 hours later, I almost wasn't allowed to check in because they couldn't find my reservation."
Pros: "Airplanes are newer with onboard entertainment of all sorts for both adults and kids alike. Seats are comfortable Checking in was a very quick easy process"
