Scores according to KAYAK customer reviews
Cons: "Best airline"
Pros: "Staff excellent"
Cons: "Seats that go flat so u can sleep on long flight"
Pros: "Crew very efficient and professional"

Cons: "Breakfast/snack is very bad, but no airline provides anything decent."
Pros: "Crew, entertainment and food was good"
Cons: "OMG!!! Leg room is inexistente... Lufthansa has the most uncomfortable seats ever. You really feel like you have the person in front of you sitting on your lap and the people behind kept complaining because we reclined our seats to have some space to gasp some air !!!"
Pros: "We were flying on their newest Airbus A350-900. It’s a bummer. More seats, less room, not a very nice experience for eight hours. Packed in like sardines. I have travelled LH to Eu the last six summers. I intend to look for a new airline."
Cons: "They have cut back on everything: food, service, breathing space. Their breakfast was truly a joke-a small muffin, four tiny pieces of fruit, and a package of two Oreo cookies. For breakfast -agh. And their reduced staffing barely made it around to serve coffee before we landed."
Pros: "Big airplane:)"
Cons: "I like Lufthansa but but I was on standby this is stressful this I don’t like. Over book I’m sorry but service awesome"

Pros: "I like Lufthansa, I feel safe with them. Crew was nice, flight Chicago- Frankfurt very comftarble."

Cons: "I was surprised that flight attendant ask to close the bins that flight will not be delayed."
Cons: "Airline lost my luggage on the last leg of our trip."
Cons: "Still didn't get to destination. Two hours delayed was enough to make me miss the connection flight which result in a extra 7 hours wait in Munich for a 9 hours total. But they compensate all that with a 10 euros voucher, well worth the trouble."
Pros: "Missed the connection"
Cons: "Felt helpless and frustrated."
Pros: "The planes of United Express are shabby. The service is unreliable. This was the last flight to Cedar Rapids from Chicago on the 14th. It left on time, which I regard as a miracle. That flight is chronically late or canceled. So I felt very lucky, especially after a long flight from Israel. The crew was nice however."
Cons: "I have already indicate that in part. The planes are shabby and the seats are fairly uncomfortable. The good thing about this particular flight is that the person at the gate who organized the boarding, changed my seat to one where there was no one else sitting next to me."
Pros: "My highlight for the travel was the AMAZING flight attendant named JENS. He is a bright soul. Positive, sharp, witty, and humorous. Just what I needed on a 8 hour flight over the Atlantic."
Pros: "Lufthansa crew is the best"
Pros: "we flew United"
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: "Every crew Member show care and respect"
Cons: "I Did Not have Any unpleasant experiențe after 9 years coming back to Cluj"
Pros: "I liked how smoothly the boarding process was at O'Hare."
Cons: "I didn't like that with a window seat, my area for my feet was diminished by some metal box. Also the entertainment options were severely lacking for adults. Only thing to watch in English were highlights. I had to turn to Children's entertainment. Plus, my screen froze at one point after being hard to function. The flight overall was very uncomfortable."
Pros: "Crew was attentive. Snack and beverage options were good."
Cons: "aisle seemed narrower. Got bumped several times as people walked by because there just wasn't much room."
Pros: "The food was good and seemed to be plenty for an airline. Most of the crew was really friendly. Just one seemed short and put out by requests. Lots of movie choices. Loved having a USB port available"
Cons: "got the back row, so no reclining, yet the person in front of me reclined so felt crowded and kinda stuck"
Pros: "Crew personable. Beverage cart shabby."
Cons: "Baggage lost in rechecking. Attendant electronically checked only two bags instead of three. Needed to hurry to for next flight. No transport by auto offered. We are 80 yrs old and I was in much pain walking. More attention to passengers needed"
Pros: "I havd to buy a whole new flight. from mechanical errors. it was horrible. I have no help"
Pros: "The attendant who did help was fantastic! The ride was smooth."
Cons: "My 12 year-old had a screen that was not working and finally we got an attendant to help us out. But until then, I had attendants who were telling us to try things and then they'd leave and not come back to check up and follow through, which left us constantly trying to find someone...one time our call light was on for 20 minutes before anyone attended to us. In addition, the bathrooms were very dirty. The breakfast was a really bad muffin that I couldn't eat."
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: "crew was helpful, seats comfortable, leg space good, entertainment good. a good flight without incident. boarding and getting off plane went smoothly."
Cons: "vegetarian meal had no protein, just white rice. Vegetables were good. Breakfast meal was very light, almost all carbohydrate. Some protein would have been helpful."

Pros: "on time departure, early arrival, decent food, great entertainment options, smooth flying, friendly crew and gate personnel"
Cons: "Seats are thin and barely comfortable (just like every other airline's)."
Pros: "Private screen for movies and music was wonderful. Blanket and pillow waiting on seat for you. Meal and drinks were very very good! Wonderful flight."
Cons: "Very strict instructions on when we had to close our window and when we had to open it."
Pros: "service was great. can't complain."
Cons: "Flight was canceled. They packed us on another one 3 hours later. Crying babies, bad food and uncomfortable, squishy seats made the flight unpleasant."
Pros: "Timely distribution of meals/drinks, uncommonly quick boarding and ... unboarding. I travel with a musical instrument and some airlines want to check it and some even insist on checking it, even though there is always plenty of room. This was a completely full flight and no one even mentioned the possibility of checking it; they put me in an early boarding line and put it in a closet. The way they handle this for myself and the other passenger with an instrument made our day, as well as making boarding smoother forbus and everyone else. Really excellent job on that!"
Cons: "Old televisions with somewhat limited entertainment options. Im tall and every seat in coach is too small for me, but thats the case on every flight ive been on."
Pros: "Pretty smooth flight"
Cons: "Entertainment options weren't great"
Cons: "From the boarding to the landing this crew could not have been more rude. Flashlights in the eye when trying to sleep, rude comments, rude attitude. They are clearly not here to make our flight easier."
Pros: "Nice crew and comfortable plane"
Cons: "The vegetarian meal was the worst we have had on an airplane. The main course was just rice with some kind of red sauce and the rest of the meal was just poor quality vegetables and fruit. the breakfast served everyone was poor too."
Pros: "Most of the aspects of flying"
Cons: "There is a fair amount of room for improvement when it comes to Lufthansa airplane food"
