Pros: "The flight was on time, the crew was pleasant and looked like they enjoyed working in the air."
Cons: "Our second time on a 787 Dreamliner across the Atlantic as about the same as the the first. The seat pitch is very tight so when a passenger reclines into the next row the seatback nearly touches your face. The Dreamliner seats seem to be very hard and it's difficult to get comfortable."
Cons: "No AC for an hour before takeoff - very uncomfortable. Audio for tv did not work."
Cons: "Flight was delayed a bit due to a couple passenger booking/misc issues. 1st class didn’t get gate bevfood service. Oven was busted so my meal wasn’t available. Entertainment console had all channels functional except — not really an issue I just really wanted to have ESPN playing in the background"
Pros: "Son got wings, so was happy."

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: "It was delayed"
Pros: "N/A"
Cons: "Chinese Eastern did not try to help and solve my problem."
Pros: "There was a bit of a mixup in boarding the plane but otherwise the flight was good. There was no entertainment system on this short flight.

The premium seats were very comfortable ."
Pros: "Short flight"
Cons: "Flight attendant was not willing to go above and beyond as he stated he would. My husband asked for a coke and the flight attendant told him he could only get water."
Pros: "It was a smooth boarding, flight and exit out of the plane."
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: "Snacks, cleanliness and crew"
Cons: "N/A"

Pros: "Very friendly and professional gate agent and flight attendant"
Cons: "I was unable to fly at all due to a spelling error on my ticket. The airline refused to alter the ticket. Worst experience of my life, ruined my Christmas"
Pros: "Very nice flight and attentive staff. Enjoyed the view of NYC as we flew up the East River, then looped over Nassau County to approach LGA."
Cons: "The male flight attendant who handed out the complimentary drinks and snacks acted a bit strangely. I was very thirsty, and I asked him if I could keep the rest of the can of soda. He neither said yes nor no, but rather completely ignored what I said and just poured my drink and moved on. I was a mildly annoyed, but figured maybe it was policy and he was shy and didn't want to debate the matter. When he took care of the older couple behind us, however, things got really strange. He asked them whether they wanted pretzels or peanuts, but they misheard him and asked for a ginger ale. I happened to know that he did have ginger ale, since my wife had just gotten one, but rather than just pouring the old folks a drink, he repeated himself. "Peanuts or pretzels?" They misheard again and asked him whether he had a diet ginger ale. Again, rather than just pour them the drink, he repeated himself. "Peanuts or pretzels?" This went round and round a few more times -- like a poorly designed computer UI that refuses to accept anything except the correct input -- before the old couple finally figured out the disconnect and picked their snacks before their drinks. Very weird."
Pros: "Nothing"
Cons: "Cancelled my flight because I lost one of the arms"
Cons: "Layover"
Pros: "Short flight"
Cons: "Too cold Not friendly boarding agent"
Pros: "N/A"
Cons: "2.5 hour delay for no apparent reason at first (supposed mechanical issues with plane) and then waited on plane at gate for a missing pilot who never got picked up from his airport and got stuck in Chicago traffic trying to get to O'Hare. Eventually had to take pilot from another flight before leaving at 8:45 when flight was scheduled for 6:00am."
Cons: "Had a death in the family and no one would help me get back home"
Pros: "Seats were comfortable. Snacks!!! Nice flight crew."
Cons: "I liked everything."
Pros: "The Gogo Inflight wifi and entertainment did not work for even a minute. I choose flights based on their amenities and this one had offered full WIFI service which swayed me to choose to fly with Delta. I'm not sure who is to blame about this issue but I'm pretty frustrated that it was completely dysfunctional."
Pros: "I missed my flight for the first time and I was having a complete meltdown at the check in desk until the sweetest agent said "oh no worries sweetheart, let's find you another flight back home"... It seems so simple but with the morning I had, this simple act had me in tears! The kindness and patience she showed me was amazing and definitely the reason I will always fly Delta to any and every destination they are able to take me! <3"
Pros: "The food was good and was served with professionalism.It was an excellent service no doubt."
Pros: "Entertainment"
Cons: "Boarding process and food"
Cons: "Breakfast/snack is very bad, but no airline provides anything decent."
Pros: "The crew was very responsive. The dinner food was good."
Cons: "The entertainment touch screen was not responsive to the touch, neither for me nor for the other members of my family. The power socket in my seat was not working, but I could use that in my wife's seat."
Pros: "Very helpful and accommodating"
Pros: "Fly is Ok"
Cons: "Fly is Ok"
Cons: "We had reserved a gluten free meal for my wife. When I went to check in it was gone from our reservation. The crew attempted to put something together so she would have food to eat but the response from their customer support team on the phone was not great. I recommend verifying all meals twice before 48 hours out. On a 7+ hour flight this is not fun."
Pros: "Very efficient boarding process. Plane was nice. Great legroom. Plenty of storage. Flight crew was helpful and very pleasant. Food was good. They had personal entertainment screens with a wide variety of movies, tv shows and games to play."
Cons: "Liked it all. Would fly them again"
Cons: "All flights cancelled. Stuck overnight."
Pros: "Friendly and helpful crew."
Cons: "Seats not comfortable at all causing loss of sleep and terrible back ache."
Pros: "The entertainment was great with very easy to use touchpad. Great movies also. Food was good also."
Cons: "Space between the seats was less than I remember."
Cons: "too cramped to get out of row to the isle."
Pros: "comfortable seats"
Cons: "Food was small portion, roll was chilled, not warmed up. There was NO snack in the middle of the flight, breakfast was very unhealthy, all sweets!!!"
Cons: "there was delay of 2 hours and i missed my plain to next destination"
Pros: "The flight attendants were very helpful and the good was quite good."
Cons: "Nothing that can be changed. It was a long flight."
Pros: "Service"
Cons: "Tight space"
Pros: "The crew was very friendly and helpful as I was traveling alone with my 1 year old."
Cons: "Nothing"
Pros: "Everything was smooth"
Pros: "It is comfortable. Some of the crew are very nice and friendly!"
Cons: "The food is not tasty, and some of the crew are not nice!"
Pros: "Good pilots as usual new plane great service clean"
Cons: "Food could always get improvements"
Pros: "Really nice crew and service! Everyone was kind."
Cons: "I had problems with my t.v., the touch screen didn't respond / work very well. The pasta wasn't that appetizing either."
Cons: "Again 2 hours delay"
Pros: "Didn’t die."
Cons: "Took off almost an hour late. Flight personnel repeatedly skipped me for drinks, meals, etc. on plane for nearly 8 hours without a drop of water."
Cons: "Missed my flight because the baggage check in closed, but what bothered me was that the attendant did not give any solutions or help, just coldly said “you can’t get on because you can’t check in your bag” and continued to tell me that I should just throw my luggage and all my things away to at least check in and get my body on the plane. I felt like I had to coerce her for help or advice on what I should do with my situation and she didn’t really give me any beneficial help until right before my gate closed and my plane departed. As customer service, shouldn’t they offer help without having the customer feel like they need to convince the check in attendant to give them alternate solutions?"
Pros: "Movie selection, food, drinks"
Cons: "Lack of information on arrival (where to go, customs, etc.)"
Pros: "By far the best flying experience in a long time..."
Pros: "Missed the connection"
Cons: "Felt helpless and frustrated."
Pros: "The crew was spectacular. They had 20 crew members."
Cons: "Our luggage did not arrive at our final destination of Madrid. It was awful. Also, after many passengers, including us, had fallen asleep, they woke us to put our seat backs up so the people behind us could put their tray tables down."
Pros: "Attentive crew. Smooth flight!"
Cons: "All good"
Cons: "S7 asked for additional "fees" to cover flight expenses. They have charged extra for carry on luggage of 2,000 roubles. It was mentioned that it was international flight but they have refused to honor those rules. I have used the same bag on other airlines and did not have any problems."
Pros: "The crew was very nice. The hot towelettes before eating was very nice."
Cons: "Squished in the middle of a row. Unable to get up and get things out of my bag. Video screen not working. I had been looking forward to catching up on some movies ( rarely have time for to or movies usually) was disappointed to have no working screen on such a long flight. Did appreciate the effort to supply a gluten free meal, unfortunately someone added whole wheat crackers ( luckily still in wrapper ). The boarding area was mixed with people trying to get to New Jersey at the next gate making it very crowded and confusing, people found themselves in the wrong line."
Pros: "The flight was on time, smooth connection"
Pros: "Depart on time. Entertainment excellent"
Cons: "All good"
Pros: "Attention on the counter and at the boarding gate were excellent"
Cons: "The in flight entertainment system was broken, they changed me seats however that one wouldn't lean, after that went back to the original seat. In the second flight a baby was crying and they did nothing to remediate the situation for those that were around him. In the end I had a very bad flight"
Pros: "The flight crew was lovely, and the best part of the entertainment was the on plane cameras which we could watch. Very cool!"
Cons: "Gluten free meal for breakfast was a turkey sandwich?? I would have preferred yogurt"
Pros: "Overall good experience. I don't expect much for food on planes and dinner was acceptable."
Pros: "Aircraft crew and operations were excellent."
Cons: "My original itinerary was booked with Airfare.com with a 93 minute layover at ORD, subsequently abbreviated to 40 minutes. Despite my repeated requests, neither Airfare.com nor United nor Lufthansa were willing to adjust my consequent itinerary to correct that conspicuous deficiency. Instead, both United and Lufthansa representatives repeatedly assured me that the 40 minute connection would present no problem; and Airfare.com tried to extract a 33% premium on its original sale to make any such adjustment. As it turned out, my apprehensions were realized when boarding and tarmac delays at SFO consumed the entire layover, and a subsequent gate delay at ORD frustrated the commendable efforts of the flight crew to facilitate the de-boarding of passengers with close connections. Contrary to United and Lufthansa's explicit reassurances, the long run halfway down one concourse and all the way back up a second left me four minutes short of the gate closure. You guys need to get your act together. If either airline chooses to finance its operations by selling tickets to an "aggregator", such a business practice should not relieve the airline of its obligation to provide reliable service to its ultimate customer, the flyer. I am currently working to identify an appropriate regulatory agency to whom to report this cynical misrepresentation of services and the patently corrupt business model upon which it is based."
Pros: "Everything was good, on time and without problems"
Cons: "Chairs might have been more comfortable"
Pros: "Worst flight experience EVER"
Cons: "Still have not found our lost bags"
Cons: "The 24 layover in Chicago with no possible flight out. If I didn't make the rescheduled flight, I would have been at least 48 hours in the airport waiting on another flight. Because I was unfamiliar with the area and was not offered any accommodations, I didn't sleep the entire time I was in Chicago. I also had to stand in line for a very long time and by the time I was done rebooking my flight all the airport restaurants were closed. I understand there are flight cancellations, but it just would have been nice if the airport was a little more accommodating."
Pros: "Service and food were excellent."
Cons: "Every seat had headphones, but the plug didn't fit the available jack. If we hadn't brought our own earbuds it would have been 9 hours of silence."
Pros: "Lots of movies."
Pros: "Hats off and Thank you to the Man behind the counter at the gate. My knees are bad and I walk with a cane, he ensured I was transported safely and in time to the new gate when we had to switch gates because of plane issues."
Cons: "When a couple of ladies boarded and were going to be seated in the exit isle. going by the color of their skin and the clothes they were wearing, the stewardess with long blonde hair, assumed they did not speak English, and rather rudely told them that they should not be in this row. To which they responded in prefect English. told her they were comfortable with the emergency seat and helping passengers. She kept pushing them and finally they switched with a couple other passengers. VERY RUDE!!!!"
Pros: "This flight was cancelled"
Cons: "This flight was cancelled and we were rebooked on the 10:30 flight to Frankfurt"
Pros: "Excellent crew and very attentive, excellent seats most comfortable. Food was great. Very nice aircraft. Exceeded my expectation. Would recommend to everyone and would love to fly Lufthansa on our next trip!"
Cons: "Nothing that we can think of!"
Pros: "Entertainment was great!"
Cons: "Sat in the middle of 4 people for a long flight...was not able to sleep at all."
Pros: "Attentive, friendly staff on flight. Choice of meals, good food and drink. Plenty of restrooms in economy. Good overheard and under seat storage. Information over the speaker system was shared in German, English, and sometimes French. Individual TV screen was nice. Good smooth flight. Boarding and deboarding were painless, even in economy."
Cons: "Economy seats a little too close together for a long flight. However, economy seating was comfortable. If possible, sharing information about where to locate customs in the arrival airport, would be a nice addition."
Pros: "None"
Cons: "I used to reserve seats without fees, but Lufthansa airlines requested a fee when I tried to reserve seats in advance."
Pros: "Luggage came pretty quickly."
Cons: "A female member of the cabin crew was rude to one of the passengers (either Latino or Middle Eastern), who was unable to fasten her children's seat belts and informed the crew shortly before the take off."

Very comfortable for this kind of airplane : Canadian bombardier

Boarding in the heat was not pleasant

More than 2 hours late and no food because of a problem with the catering. The flight was super full and there wasn’t enough space for the hand bags. A lot of space for improvement.

Main trouble was with Kiwi -- a partner booking organization through Kayak. Even though tI booked well in advance they did not assign me a seat and I came within a minute iof getting bumped from the flight. On the return trip the airline sent me an ominous message that I had to provide additional info before I could receive my boarding pass and that if there were problems I would get a refund. That caused unnecessary stress since the airline just needed my home address. Kiwi should have made sure they had collected all the necessary information from me before they booked my flight.

Long delay, lack of space at the seats (not comfortable).

We made the boarding and then waited inside 40minutes before taking off The plane was too full It was probably the worst flight of my life in terms of comfort. I was in the central seat, and on my right i had a very big person who was occupying part of my seat since he did not fit in just one. I think in these cases the staff should notice and do something about it. I checked if there were available seats by myself, but it was all full. Maybe in business class there were still available seats though.
