Scores according to KAYAK customer reviews

Pros: "The cabin was to warm"

Pros: "Everything! Thank you"
Cons: "Nothing. Thanks"
Cons: "Food really bad on both segments."
Pros: "The crew was amazing."
Cons: "Compared to Virhin Australia crew, Delta staff seem almost poorly trained in comparison. For example, Drlta crew don’t check your pass, don’t immediately move down the aisle to move along tourists busy discussing their seats and then line up for Boarding seems chaotic at best."
Pros: "Seat was decent and only a $10 upgrade. Worth it!"
Cons: "Wasn’t clear what boarding group was up. I don’t usually fly delta so maybe I’m just not used to the system but something on the video screen at the gate saying where they were in boarding would have helped. I wasn’t the only one that seemed lost."
Cons: "Departure delayed by 1hr30"
Pros: "The food was improved and the seat was comfortable."
Pros: "Awesome prompt and courteous service."
Pros: "Super friendly staf, big enough seat, good enough food, enough room for luggage."

Pros: "I loved flying delta comfort. I’m going to do it more often."
Cons: "Old cramped untidy and limited drink service"
Cons: "Multilpe delays"
Pros: "This was our first time flying Delta and it was a very pleasurable experience. Boarding was very straight forward and the seats allocated comfortable. A surprise for us was being asked if we would like to move seats from the back of the aircraft to Comfort Economy (we think it was to do with weight balance! but appreciated very much none the less). The flight attendants were very professional and helpful, as you would hope all attendants on all airlines would be. We'd gladly fly Delta again anytime."
Cons: "Too many announcements"
Pros: "Alaska Airlines is way overpriced and way less comfortable than Delta. I’m a Delta loyalist forever now!"
Pros: "Nothing really"
Cons: "Flight delay further to the 30 minutes additional 20 min due to crew being not there"
Cons: "We waited 3 hours for the tarmac in Seattle On Christmas"
Pros: "Makes all the difference to have Flight attendants and pilots all wonderful. Gratefully, ~Elana"
Cons: "Too crowded."

Pros: "Fast and efficient boarding again! Most impressed!"
Pros: "everything was very nice"
Cons: "As a Platinum AFK/KLM Skyteam member I was NOT allowed to use the Delta Lounge. On the flight the meal choice was poor and the staff were not really geared to serving regular clients. The movie choice was poor. I expected better!"
Pros: "Enjoyed food and movies.Woul"
Cons: "Would like more comedy or romance movies. Becky"
Cons: "Late and missed my international connection"
Pros: "Free entertainment and free food was unexpected and very welcomed, especially given the trend of charging for more and more features."
Cons: "*Again, my first choice of main off the menu, in Delta One, had run out. *Not a fan of the Delta One seats."
Pros: "Availability of flight. Quick flight, on time. Signage at PDX is good. Easy to find where you need to be"
Cons: "Layover, confusing mob line at checkin."
Pros: "Getting to China, albeit two days late."
Cons: "The fact that the lack of knowledge regarding international travel visas by the counter staff and supervisor meant that two days of the vacation were lost. Upon arrival in China the 144 hour travel visa was granted with no problem within minutes, but the U.S. staff was completely befuddled by the possibility. The interrogation was completely stressful and resulted in a reschedule of the original flight and during the second attempt at flying even an email from the U.S. consulate with a link to the Shanghai/Chinese government immigration site was deemed "not official enough". i will be expecting proper compensation. I was once given an $850 travel voucher for voluntarily giving up my seat, and was flown first class to Hawaii, given 4 star accomodation and then flown first class on to China within 48 hours. This was an involuntary bump from our chosen flight time, all because of a lack of knowledge about current visa regulations and international law on the part of the check in staff. We have been loyal Delta users for over 15 years, and this was the biggest blunder ever. Also humiliating and extremely frustrating, stressful and a big problem with fulfilling our travel plans between son and father."

Cons: "Nothing to be honest . All positive."
Pros: "Crew was courteous and polite! Entertainment system had some great movies at no additional cost."
Cons: "Poor communication between delta, KLM and Air France meant that I couldn’t check in online and get a digital boarding pass. Furthermore I couldn’t use the check-in kiosks because my name was listed as Reidmr instead of Reid, which meant that my boarding pass did not match my passport. Overall this caused unnecessary delays that were compounded by the fact that I couldn’t use my TSA precheck. My main problem on the plane was that I had to struggle to get water served to me. It’s always so dry on planes and I would have liked to be able to get more than one tiny glass of water at a time. Also, would have loved a window at my window seat. Plus no WIFI!?"

Pros: "staff was fine"
Cons: "old old plane, very uncomfortable. Tiny bad screen made movies pointless"
