Pros: "Amazing"
Cons: "Nothing"

Cons: "It was fabulous as always! Thank you. I love Delta!"

Cons: "Too hot. Bathrooms were dirty. No leg space in comfort+."

Pros: "Great seat and always on time."

Pros: "The cabin was to warm"
Cons: "The cabin was to warm"

Cons: "Announcements were too loud in earphones (could damage ear drums) and entertainment was turned off while waiting 30 min for the gate to open."

Pros: "Everything! Thank you"
Cons: "Nothing. Thanks"

Cons: "Food really bad on both segments."

Pros: "The crew was amazing."
Cons: "Cleanliness"

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: "Nothing"
Cons: "Nothing"

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"

Cons: "N-S"

Pros: "The food was improved and the seat was comfortable."

Pros: "Awesome prompt and courteous service."
Cons: "Nothing"

Pros: "."

Cons: "Old cramped untidy and limited drink service"

Pros: "Nothing"
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."

Pros: "Great"
Cons: "Too many announcements"

Pros: "Alaska Airlines is way overpriced and way less comfortable than Delta. I’m a Delta loyalist forever now!"
Cons: "Nothing."

Pros: "Nothing really"

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"

Pros: "Clean & modern aircraft Comfortable seat Proactive customer service"
Cons: "Delayed departure (due to Air Traffic Control) Finding my bag damaged on arrival More refreshments would have been nice"

Pros: "Very friendly and helpful staff."

Pros: "Fast boarding, everyone nice."
Cons: "Wifi was yo and down the whole flight, about 20 times, so kids were not entertained."

Pros: "This was a first! The flight attendant (sorry I didn't catch his name) was very attentive and assisted us in first class as needed. He actually addressed us by our name and that made me feel like I was not just a passenger!"

Pros: "Very attentative."

Cons: "Aircraft was smelling bad! Hygiene is the key"

Pros: "EZ play newer plane nice staff"
Cons: "Power plugs did not work in seating row and air vents did not work"

Pros: "Helpful staff. Never felt rushed if I had a question. The special meal (VLML) was excellent. Tasty, filling and nutritious Plenty of foot room in economy."

Pros: "Nothing. Delta sucks!"
Cons: "Poor management prior boarding"

Cons: "Enforce your baggage size and number limits. A significant number of passengers take bags onboard that are oversized."

Pros: "TV/Movies were a welcome distraction"
Cons: "The flight was an hour late and I missed the meeting I was flying for in the first place"

Pros: "Even with a 90 minute delay getting out of Seatac caused because some one checked their luggage but didn't get on the plane, Delta made sure that everyone made their connecting flights in Tokyo. In my hurry I left a charging cable on the late flight but right after I got settled on the next flight, and before I'd even figured out that I'd left it, a Delta attendant handed it to me."

Cons: "There was no amenities pack given in Premium economy. The food was ok. It would have been nice to have been offered another bread roll. Seat comfort was fine, but I kept getting hit by the separating curtain as the flight attendants went back and forth from economy."

Pros: "The seats were much more comfortable then my last flight. The entertainment system was also updated from the 1980’s remote and cord ones on my flight from DC to Paris."
Cons: "There was no food between the two meals on an 8 hour flight. I had a flight attendant rudely tell me that there is nothing to offer until the next meal. No one reached out to me about the horrible flight and comments I made from the last flight."

Pros: "Crew attentive. The delay was due to airport conditions in FCO, cannot be blamed on Air France."
Cons: "Food. For a 2-hour plus flight, from 11am to 1:30pm, we got 20gr pretzel sticks. This is ridiculous. Don't pretend you are not low-cost! Formerly, before the Joon failed (thank God) venture, Air France had real sandwiches around that time of the day on that line."

Pros: "Nothing"
Cons: "Everything"

Cons: "Seats are not comfortable for long haul. Airbus 380 premier economy. Not enough reclining and leg support."

Pros: "I like the comfortable seats"
Cons: "Service lag a little"

Pros: "All went right namely the seats but the luggage condition is the worst"
Cons: "Air France is not a low fare airlines, I had to pay 225 USD against 3 luggages which is not acceptable. We should have the right for one luggage per ticket as all other airlines. If I knew this will happen, I wouldn’t use Air France and this will be the last time I buy a ticket on Air France"

Pros: "Food"
Cons: "Seat"

Pros: "I'm not Hindu, but I requested Hindu Vegetarian meal. It was very tasty and enjoyable."
Cons: "Seats were not comfortable, even in Comfort + seating isle."

Pros: "On time, no hassle."

Pros: "Tight seat, was moved out of exit row because of my age"
Cons: "Could have stayed in exit row. Plan arrived in Moscow late so flight was over one hour late"

Cons: "Placed in last row w/ non-reclining seats, even though bought tix 7 months early. We travel w/ only carry-on bags. AF allows 35 kg each but only 12 kg in cabin. I asked, online, twice, if we could have a couple of extra kg for hand pieces. Rec’d only auto. luggage policy. Forced to check both bags."

Cons: "My entertainment device did not work the entire flight."

Pros: "Most of the crew tired especially hard to keep everyone comfortable and safe. The food was absolutely amazing."
Cons: "Other members of the crew were snarky to passengers and dismissive of questions from passengers during the early stages of the delay. We were all trapped on board for about 4 or so hours without much communication from the crew or captain which made me very anxious. We arrived 5 hrs late and it put my whole trip in jeopardy. Based on this experience, I eont be inclined to use this airline again for future trip planning. This airline will need to work hard to earn my trust back because i felt physically and emotionally unsafe throughout the experience, many times."

Cons: "I didn't get to board, ended up spending $2,400.00 over and above the $980.00 that I spent booking the initial ticket. I was not informed when I booked the ticket that when you transit through 2 schengen countries, you need a transit document. I was informed about it at then airport. Not only did I miss my flight, I had to book for the next day at a outrageous price. SUPER BAD CUSTOMER SERVICE...BOTH KAYAK and PRICELINE. Will never recommend you guys to anyone."

Pros: "Leg space was great, food was delicious, alcohol served 3-4 times, and the in-flight entertainment was spectacular. I saw 4 movies and slept somewhat comfortably for once!"

Cons: "Not much legroom."

Pros: "Food was good, crew was very professional and courteous. Flight was smooth."
Cons: "Coach was cramped and the video system didn’t work very well"

Pros: "SFO - CDG (Air France) was a great journey in all respects. But the one major reason for that was, the middle seat was empty. I was so fresh after the journey, would definitely recommend this flight to anyone."
Cons: "The flight was delayed by atleast 45 mins and therefore had to rush at the CDG airport to catch the next flight."

Cons: "Our flight was delayed so we could not make out connecting flight. We had to wait 6 hours get another flight to Atlanta and then fly to Boston the next day, longest flight ever was horrible I called out sick from work too."

Pros: "The only thing that I like about the flight was that it was easy to boarding"
Cons: "The food was not heat correctly it was cold and I felt that the crew rush to give out the food. The seats are terrible, if the person in front of you reclines you won’t be able to see the screen if your watching a movie and you will see the top of the persons head."

Cons: "Leg space."

Pros: "Ground crew at CDG was helpful to file a claim for the lost luggage."
Cons: "Ground crew at MXP Was inexperienced. She called every one in my flight to form a new line and it was immediately total chaos. And then they lost one of our luggages!"

Pros: "The plane arrived in New York smoothly"
Cons: "They lost my luggage and have no information as to where it is. It has been 3 days and no Information. There was only one meal for the flight and alcoholic beverages were not included."

Pros: "Yelling, cheering and literally rolling in the aisle made for a really annoying flight"
Cons: "Infusions bad behavior. Also, flight number was changed and AF. Was understaffed to handle questions on squirrelly luggage check."

Cons: "Took very long from landing/ arrival until baggage could be collected. Priority luggage came out last!"

Pros: "The crew took care with calm and kindness of a man in deep distress and erratic behavior. Impressive. More generally , the crew showed respect and attention to all passengers. Not frequent."

Pros: "The food, entertainment, and service. Waited for me after almost missing my flight."
Cons: "Nothing."

Pros: "Staff was nice"
Cons: "Very cramped. Poor leg room also with.metal bars under seats that further. Limited foot room. Terrible options in movies."

Pros: "Everything was very prefect and would love to fly again."
Cons: "NA"

Pros: "None"
Cons: "The airlines didn’t even notify the passengers with the connecting flight. As the arrival was little late, all the passengers have missed their connection flights in Toronto and there was no notification or communication made on the new flight. When I went to the Air France counter in the airport, the staff has gone for the day and trying to get a hold of telephone rep took 2-3 hours and I by the time I found about my new connection, I was already late. Somehow I managed to get to the Terminal 1 and when I spoke to the lady (indian) at the Check-In counter, she has refused me to Check-In because i slipped the line up. The people in the lineup didn’t have any objection and they let me go first for Check-In as I’m already late to my flight. I wante to say something to her, but I’ve controlled my frustration. Luckily the other person in the Check-In counter offered to help me Check-In. Here is my word to the Indian lady staff “F**k You B***h” - learn some people skills."

Pros: "Nice food Right in time Police and customs formalities easy"
Cons: "Poor comfort in business class No entertainment at all"

Cons: "My baggage was broken"

Pros: "The check in process was much better in the CFG airport than SFO. Very organized."
Cons: "The food was mediocre on this flight. The seats also are surprisingly uncomfortable."

Pros: "The seats are spacious. They give you great amenities such as a toothbrush, etc. The crew was very nice. The food was also superb for airplane food."
Cons: "The check in process was terrible at SFO. We all felt like cattle being herded on. It was such a mess. The seats are surprisingly uncomfortable in premium economy. The headrest is not conducive to sleeping."

Cons: "Had to check in our underweight small carry on because there was no space left. Left out hotel at 3.15am. A dry croissant did not satisfy three hungry children for breakfast, the coffee was terrible and the seats too close together. Not a good experience."

Cons: "the food is terrible."

Pros: "Priority boarding"
Cons: "Premium economy seats do not recline, only slouch. One of our 2 seats wouldn't slouch more than half way. The entertainment options are extremely sparse and the screens are 4:3 ratio, tiny, and of such poor quality that they look like laptop monitors from 1999."

Pros: "No issues, quick trip, friendly staff, comfortable ride..."

Pros: "Crew was great"
Cons: "Not enough food"

Pros: "Cheap aircraft, not even headsets"
Cons: "Dirty aircraft, I expect more when I pay a lot"

Pros: "Flight arrived safely."
Cons: "Air France offered no help rebooking missed connection at JFK due to delay of more than 2 hours in arrival."

Pros: "It was a short flight."
Cons: "Seat to seat space OK for anyone under 4 ft tall. Pressed intoth seat framein front, I couldn't even turn or get my feet under the seat to extend."

Pros: "I like that they still feed you and provide alcohol for free, even on a 40 min flight (unlike BA)."
Cons: "At one point during the flight I took a video out of my window with my camera, a member of the cabin crew barked at me in French. In bewilderment I asked her in English to repeat herself and she sarcastically repeated what she had said, in French, I asked for her to speak in English (which she had done to me previously on this Paris to London flight) yet again she scolded me in French. I was left absolutely none the wiser and it left a bad taste in my mouth."

Pros: "I had a choice of movies, games and music that was very appealing. My concerns about not receiving the correct meal was handled professionally and promptly during the flight. I was surprised they couldn't discover I only ordered it for the second leg of my flight."
Cons: "Being placed into a window seat at 6' 5". Although I opted for general seating rather than paying for a extra leg room which is out of my budget. Not getting an aisle seat was disturbing at my height. Then there was the guy in front of me not willing to forego putting his seat back on my knees for over half the flight. It would be nice if the seat assignments for general boarding considered the height of the person being assigned."

Cons: "Left a little late for no apparent reason."

Pros: "I liked their seats, I had enough space to get comfortable flying internationally for 14 hours."
Cons: "Just wish they served water a couple times more, because when you're in the plane for the whole day, 2-3 little cups isn't enough."

Pros: "The in-flight entertainment wad quite nice, even though the screens were old."
Cons: "The vegetarian meal was tasteless. I expected way more."

Pros: "Clean plane, efficient crew, food OK. Boarding was organized"
Cons: "No entertainment and no power plug to charge devices."

Pros: "Professional and helpful crew."
Cons: "Food - two meals, one "hot pocket" item in each. Was not good. Noise level in the back of the plane from engines, very loud. Difficult to hear with headphones, volume very very high. Tray table was difficult to latch, recline feature of seat did not hold in place, bounced."
