Scores according to KAYAK customer reviews

Cons: "Late and bumpy"
Cons: "Stop being LATE!!!!"
Pros: "Everything went smoothly. Even though we were delayed for 10 mins We still managed to make it to NYC on time. The crew was friendly. The entertainment was exceptional. Really I have no complaints. I am so happy that they were able to accommodate a seat change at no charge as well."
Pros: "Seats more comfortable, plan wasn’t too full"
Cons: "No charging port for cellphone."
Cons: "Cabin was too hot since the very beginning. Even in first class."
Pros: "Pilot was courteous, pleasant and kept us informed of flight status."
Pros: "Boarding, friendliness of staff"
Pros: "Some of the cabin attendants were friendly and helpful. Others not so much."
Cons: "Even in "world business class" the pods are very small and cramped and there is no room to put a carry on bag even something as small as a headphone box. Also the business class bathroom was very small, very disgustingly dirty when we boarded (someone tried to clean it a bit) and dirty and small throughout the flight. The bathroom does not have ventilation and the toilet basically does not have any liquid for flushing!"
Pros: "On time departure/arrival despite weather in Atlanta. Always a fan of free messaging and choice of snacks."
Cons: "Delta needs to invest in their gate area at ORD. Understand it’s not a hub but it’s a key business/leisure destination. The MD-80s are ok for a short hop but over 1 hour unless you’re in Comfort+, it’s tight."
Pros: "Same exact comments as first flight"
Cons: "Not a complaint"
Pros: "Not much"
Cons: "Almost everything. The flight boarded late but quickly. We sat on the runway for hours. We were VERY delayed for RDU arrival. Luggage was slow in getting to baggage claim. Not enough help with baggage was available."
Pros: "Fantastic Pilots and a great flight attendant."
Cons: "Delayed flight"
Pros: "Buen entretenimiento."
Pros: "Enjoyed the flight and the attitude snd professionalism of the Delta staff. Only negative is that my entertainment screen did not work at all. The flight attendant tried resetting it but that did not work."
Pros: "Everything was so very nice. The seats were fantastic in First Class. So comfortable. The service & food were delightful. The only negative was the screaming infant. This is my second trip on Delta in First Class in the past three months. Both times the trip was ruined by crying babies. ☹️"
Cons: "The crying infant."
Pros: "The free TV was nice."
Cons: "A tiny bag of pretzels is a stingy snack. Aeromexico gave us a croissant with two pieces of cheese,applesauce and a square of chocolate."
Cons: "Bought a brand new suitcase and Delta staff broke one of the wheels!"
Pros: "Flight team were wonderful!"
Pros: "I like the snacks they are not giving out on the flights. It seems that Delta is trying to make the flying experience nicer instead of more tedious and uncomfortable like many other airlines, which is appreciated."
Cons: "The flights were both operated by Delta but booked through WestJet, and the flights themselves were fine. The booking was through WestJet (found the flight on kayak which kicked me over to West Jet's site) and check in was a pain. Their code did not work for their site or Delta's, I had to FB message them both leaving and returning to ask for the correct one, and the first request took them hours to answer. I'll just book Delta next time and save myself the trouble."
Pros: "Alaska Airlines is way overpriced and way less comfortable than Delta. I’m a Delta loyalist forever now!"
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."
Cons: "Long wait for de-Icing. Got on and off the plane 3 times. First wait was 1 hour, but plane aborted takeoff. Second plane waited at gate with all aboard for 2-1/2 hours and never got slot and de-planed. Third plane waited 1-1/2 hours for de-Icing and finally we were headed home. Arrived 8.5 hours after schedule."
Pros: "No wifi couldn’t do any work"
Cons: "Was looking forward to completing some work but the wifi never came on."
Pros: "Fligth were on time"
Cons: "My flight from Montreal to Atlanta was 2:30 min Left at 6:10 arrive at 8:30 roughly Tried twice to get to my connection earlier and get 9:30 instead of 12:09 fligth to Daytona Delta was not flexible to allow me to book saying i did not have 55 min in between fligth which i had than lear n it will cost $75.00 to change the fligth - What? Very disappointed of Delta - lost 3 hrs at the airport today"
Pros: "The stewards and flight was overall fine. In fact I found the stewards to Atlanta from West Palm very accommodating."
Cons: "I have reservation on booking Comfort plus next time I fly though. There appeared to be no difference in the seating or service as economy. A lesson learn I guess. I will atillflyDelta but stick to economy. I saw no perks"
Pros: "At least they serve us dinner."
Cons: "The toilet was very sticky. over crowded and kids was crying all over the flight."
Pros: "Let’s face it-no one likes a 14 hour flight. But the staff was great, food pretty good, movies flew by and we arrived early and happy and bags at baggage claim by the time we got"
Pros: "Empty seat next to me and actually got to stow my bag overhead. Good entertainment options. On-time departure and arrival."
Cons: "Wi-Fi not functioning for second flight in a row. No food available for purchase, not even snack boxes. Best I could get was three bags of almonds."
Cons: "The crew could have been more friendly"
Pros: "I got to destination. Baggage claim was quick."
Cons: "Flight was delayed due to waiting for a tardy flight attendant. Landing felt a little hard. No announcement about baggage carousel prior to disembarking."
Pros: "The movie I watched was pleasant, although I had trouble hearing it because of the situation described below."
Cons: "There was a family seated behind us with several crying, loud children. We were miserable. Even my headphones with a Mozart sonata cranked up to loud did little to mask the noise. Probably not Dela'a fault, but the crew did nothing to mitigate the problem."
Pros: "Comfy seats"
Cons: "No earphones available. I had forgotten mine but crew stated that none had been put on the flight. Lunch was served but no snacks later as is usual on an almost 4 hr flight. I always fly First Class for the extra room and perks of crew service. Crew spent most time in galley chatting. Not a bad flight by any means but I guess I have been spoiled by superior service on all of my other weekly Delta flights."
Pros: "In flight entertainment interface and options were great!"
Cons: "Very uncomfortable!! Spent the entire flight with my knees pressed against the seat pocket. One flight attendant was somewhat rude and unpleasant."
Pros: "Staff as always was very attentive and courteous. The board process proceeded smoothly and we were able to depart a few minutes early."
Cons: "One attendant did display a slight level of un-professionalism after spilling a drink on my mom and not apologizing. I chalk it up to her embarrassment and she probably just forgot."
Pros: "Great service"
Pros: "Crew was fantastic and I really enjoyed having multiple USB ports to keep my devices charged."
Pros: "I didn't like anything about this flight. Only benefit of the doubt is the 2 hour delay as a runway in SF had shut down."
Cons: "We had seats at first where there was what looked like bubble gum bits stuck on one of the food trays. The flight was clearly not cleaned although it landed 2+ hours before the departure. We had to ask for a wet tissue and clean it up. That was of no use too as it wouldn't scrub off. My wife was feeling under the weather and so we asked for a blanket. The blanket was hardly a blanket and more like a towel. We then luckily could switch seats as there were 2 vacant. But, the air conditioner was leaking water in the seat to our left. The crew was callous and just stuck the passenger with some napkins saying it does that. I don't fly Delta a lot and my experience in this trip isn't inspiring much confidence."
Pros: "Arrived sooner than expected! Nice, smooth flight despite cloudy, rainy day."
Cons: "Everything was fine."
Pros: "I was notified about the delay via text before I left for the airport, which was nice. I would not have checked my email."
Cons: "Delayed for over 2 hours. I have never flown Delta before this flight and it wasn't a great representation. The flight attendants were nice but I was in a seat near the engine and it was making really weird noises. I fly almost every two weeks, so I'm used to engine noises but this was one of the loudest/most rickety sounding flights I have ever been on.. and I have flown Spirit a few times. It just didn't feel safe. Landing scared me a little too as I have landed in O'Hare countless times and have never flown so low to the highway upon entry. It felt like we were only a couple hundred feet above the cars."
