Airline reviews

Pros: "Crew, food, and business class pods were super. In fact Lufthansa itself was great BUT read next..."
Cons: "...debarkation at SFO was dismal. The nearest bathroom upon debarking was closed for cleaning. The passport control signs were misleading and confusing (the term "residents" was misused). And there was no one at baggage claim to prevent bags from piling up atop each other on the conveyor. I received a bone bruise trying to get my bag off another one. Avoid SFO as an international destination if you can...horrible airport."

Pros: "Great crew, especially on a long-haul flight. Decent food, considering how many people they were serving. Best bathrooms I have ever experienced on a large plane."
Cons: "Legroom, legroom, legroom!! If we are to be treated as sardines, at least pack us in oil. It gets worse every time we fly. Crew agreed; the airlines need to be put on notice. It makes their job impossible."

Pros: "Seat comfort."
Cons: "Food selection."

Pros: "The fight had a lot of open seats as I had a whole row to myself! Also the crew was kind."
Cons: "Flight was delayed, but it didn’t interfere with my travel plans."

Pros: "Food and crew were good"
Cons: "The seats recline back so far that it really intrudes into the space of the person behind you. At one point the guy in front of me reclined back so far and fast it slammed my eReader and spilled my coffee. Also the touch screen media app does not work well on Lufthansa."

Cons: "More leg room"

Pros: "Luggage space, comfortable seat.. huge plane"
Cons: "Ice cream was not good."

Cons: "Lufthansa’s service counter in Munich was helpful with locating baggage and unfamiliar with transit rules."

Cons: "I never fly United because the spirits aren’t free so I chose Lufthansa. You can imagine my disappointment when it became a United flight and had to pay. Lufthansa you’ve lost a customer here."

Pros: "Crew was very friendly. Seats are comfortable."
Cons: "The in-seat entertainment center did not work well - it was slow, glitchy, and needed to be rebooted on multiple occasions."

Pros: "Overall once on the flight the service and comfort were very good. Attendants were very nice and helpful. Always had a smile and made the flight enjoyable. We specifically picked this Airline for its service and reliablity"
Cons: "The checkin and "Automated" Baggage Check were a disaster. It took us a full 2 hours to check our bags and get to thru security and our gate. We were practically running to get to the end. The layout of the airport is very tough to get from point A to point B. Walking a long distance with multiple security checks. On top of that, the plane was almost an hour late boarding and then taking off. It was a mass of people with no way to cue for an orderly boarding process. No instructions or info given to allow us to go get something to eat or drink prior to boarding."

Pros: "They were great with service"
Cons: "Having to have to close my window shade so I couldn't see outside"

Pros: "Very attentive, friendly and multilingual crew, frequent offers of food/drinks, good selection of movies"
Cons: "More a problem of the San Francisco airport than the airlines, but getting through passport control/customs involved multiple VERY long, slow-moving lines with very few people working to process the crowds. Then, even though my bags were checked all the way through to my final destination, I had to pick up my luggage and re-check it, and go through security again--and that also seemed poorly organized and/or short-staffed."

Cons: "They had one guy checking passports and he was being trained. Someone asked if there was anyone trying to get on the SF flight and a bunch of us raised our hands, but they didn't do anything. We had to run like OJ to make our flight. Not fun. Then the AC wasn't working while we sat there."

Cons: "First time took Lufthansa airlines and it was my one of the worst experience. Hospitality is respected when customer is helped when they are in trouble not when they is happily boarded. I have to travel from Milan to San Francisco and I missed flight of my one leg ( milan to frankfurt) of journeyand I went for help and non of the Lufthansa staff at Milan airport helped me. Although my connecting flight was after 12hr they just gave me some random number which to call. I have never experience this in my 8yr of international travel."

Pros: "Comfort and space comparing to my outbound flight from SFO to Munich. This plane was way older but at least there was a little bit of space. Flight attendants were very nice."
Cons: "Entertainment units kept crushing, were not responsive. Difficult to use and enjoy. Frankfurt airport - total mess at the additional passport control before going to "Z" gates. Crowd of people, huge lines, all disorganized. The control for EU passengers was not so crowded but you couldn't see it at the end of the line, so even people who didn't have to were all crowding in the same cue. Horrible experience and I almost missed my flight because of this mess."

Pros: "Food was pretty good,Lufthansa one of the best companies to fly with."

Pros: "Airplane was clean and comfortable for economy class."
Cons: "Because I felt sick I would probably prefer to pay a little more and upgrade to a better seat if the option was available."

Pros: "Asked for an extra pillow - handed that straight away. Excellent food - loved every meal, both portion and quality. Boarding process was smooth too. Pilots are always great."
Cons: "Would have been nice to get upgraded to premium economy since they had seats available."

Cons: "Requested for Hindu vegetarian meal by call and was informed we would receive on flight. Got on flight to find that Hindu vegetarian does not exist. Starved on both legs of flight. That is almost 24 hours. Plane should keep extras and customer service should give correct information."

Pros: "Excellent flight attendant in charge of us."
Cons: "The galley where the snacks were looked more like a very dirty restaurant kitchen. It was absolutely gross with dirty forks, dirty glasses, overall grimy and dirty."

Pros: "Great service and food!"
Cons: "I didn't like sitting in the middle cause it was hard to sleep and go to bathroom"

Pros: "Lufthansa arranged for pickup with a van upon disembarking from my late flight from Pisa and took me through a special passport and security checkpoint so that I was able to catch my MUC-SFO flight. Flight departed late, but pilot made up all tge lost time in flight. Crew was professional, very polite and efficient."

Pros: "Flight attendants were great, friendly, courteous and responsive. The relaxation and mediation program was great! Boarding was fluent and easy."
Cons: "No matter what you try to order on the airplane is totally disgusting. If it's not overloaded with cheese and tomato sauce then it's overcompensated with spices (salt or chili). I will never understand why it is so hard to provide simple, fresh and enjoyable meals. Chairs in economy are rarely cleaned up and one can see on the cushions that they are worn out and have lost their padding making the seats very uncomfortable. There was no foot rest available (which is such a simple addition that helps a lot) and the "holder pocket" on the seat in front was a simple net completely useless. Tables were dirty suggesting they were never cleaned and disinfected. Knowing that the highest source of viruses are the tray tables and the pockets in front I would expect attention to be focused on those- it not only impacts the health of the traveler but more important that of the crew. Why is it so hard to think of this business two fold: make revenue but mostly be kind to humans."

Pros: "Lufthansa makes coach travel tolerable. Blankets, pillows, free access to on board entertainment and a large selection of real food, not just snacks, and beverages. All beverages available the entire flight. Plane was clean and everything in working order."
Cons: "Nothing to complain about."

Pros: "The food was pretty good. Normally I can't eat airplane food but it was actually good."
Cons: "The seat didn't go back at all"

Pros: "the gate crew didn't care if there was chaos. no interaction with waiting passengers beyond those that queued up with direct questions. i'd liken the experience to herding cattle. customer service skills haven't been taught to these folks yet. if i were basing my lufthansa experience on this alone, i'd go out of my way to fly another airline next time. on the other hand, the people staffing the flight were extremely kind, professional, pleasant, personable. a much improved experience. so much so that i mentioned it to a few people once i got home. this crew has received more training on how to provide excellent service than the gate folks in frankfurt."
Cons: "gate crew's attitude. it feels as though they are disdainful of the traveller. customer service matters. manage the boarding process. be nice about it."

Pros: "The entertainment touch screen system is so much easier to use than the planes that have the remote controls. Having all of the toilets downstairs was nice. It was less noisy and had a little space to stretch. The crew was very friendly and helpful."
Cons: "Even though I was sitting on the left side aisle seat (2-seat section), it was very cramped. I'm only 5'2" and my legs were very uncomfortable. Along with less leg room than other airlines, it felt like the seat itself was narrower too. The food quality control was disappointing. The meal I had on the first leg of my flight (Mumbai-Munich), I noticed that it expired by about 2 weeks. And the complimentary water bottles also had a past expiration date (although, I don't know how water expires). Generally speaking, I think all of the meals I ate on Lufthansa were subpar compared to the many Asian airlines I've used for overseas flights. Quality could be improved and I think there's a missed opportunity to incorporate meal options correlated to the airline or international destinations (German airline, why not bratwurst? Pretzel bread?)"

Pros: "The very gracious crew kept coming by with drinks and snacks, as well as lunch and dinner (in coach).The entertainment system is top notch, with a few dozen movies, lots of TV shows and more, with screens for each seat. The only complaint is that there's not much space between seats, so that when the person in front of you leans back, things can get tight. On the plus side, the bathrooms are downstairs (down a short staircase) and there's plenty of waiting room, so you don't get the usual congestion. Overall, a wonderful experience for an intercontinental flight."

Pros: "Our first flight was late. We were met at the gate immediately after landing and were brought individually and directly to our next flight behind the scene, including passport control. Excellent."
Cons: "I wish Lufthansa would find a way to create less trash. Too many small plastic cups are used. Proved refill options rather than new cups."

Cons: "It took 90 (ninety!) minutes to get my suitcase at SFO. What a shitty, second-world airport. "Love" the crt tvs playing awfully low-quality "welcome to the US" videos. Way to showcase Silicon Valley's technical advances. Laughable."

Pros: "there was ice cream for dessert at night"
Cons: "- Delay > 2 hours and no info at gate at the time of planned boarding - unfriendly ground staff and chaotic check in - old 747, "entertainment 1970s standard - crew looked unkempt (like just out of bed), unfriendly to downright rude, my 85 year old mum was ignored repeatedly and ended up not getting enough fluids as a result - 1/8 crew members managed a smile on occasion - rushed meal "service", all they wanted was to disappear to sleep - crammed spaces - while it was announced "we have three different meal choices, you will have at least two choices" - ummm, no, it was pasta. Period. To be fair the pasta turned out ok. The morning dry ham and cheese bun was not, especially without any drink."

Pros: "Food was very good, super nice crew. Good selection of movies. Boarding was great, we are seniors, we didn't ask for assistance beforehand, but the person at the gate called us over and had us board early. Much appreciated!"
Cons: "Seats were just too cramped. We chose seats and paid extra to do that, but the seating charts really didn't give a very good idea of what to expect or how to choose. Announcements were to difficult to understand. Also in the gate area, I couldn't understand names at all. Need to slow down and speak more clearly."

Pros: "Lufthansa always departs and lands on time or early. The seats are comfortable and the crew is even better. They ran out of food by the time they got to me and my wife, since we were sitting all the way in the back, and they repeatedly apologized and brought us something from business class to make up for it. The layover time was also very short compared to other airlines I looked up. I will try to fly with them again in the future!"

Pros: "The boarding was pretty quick, the crew was friendly and efficient, they were great. Food was good. Good amount of space in economy. I loved the whole experience. I would definitely recommend flying with them."

Cons: "11 hours of crying babies was too much. The practice of placing 4 cribs together on the bulkhead encouraged one baby to set the others off screaming. The toddler siblings then started fussing, the parents were then jumping up and down, jostling the other passengers, it was a nightmare! Hated every minute of it."

Cons: "The seats recline too much! The passenger in front of me almost immediately reclined her chair right into my face, making an irritable experience on a long flight for me. That is the only flaw in your service in my experience."

Pros: "Chairs were uncomfortable, mainly due to the front passenger was always in reclined mode, and the passenger behind me wouldn't let me recline... He would literally push my chair up, but that's probably because his chair can not recline!"
Cons: "We needed to place special request on vegetarian meal, couldn't do it at booking or at checkin, was told to let crew know, they said it's too late. They brought us an "unclaimed" vegetarian meal, but it wasn't, it was Asian halal meal with lamb! After I let crew member know wmy husband was served meat instead, she denied it and said "its not possible" as the wrapper says "vegetarian". I informed her it actually said "Asian halal", she the proceeded to say, well, "i am sorry if it's wrong, but I gave you vegetarian". That said crew member collected my husband's plates while I was in the bathroom and came back later with a "vegan" plate that they now have available."

Pros: "Initially things were smooth. Boarding was on time."
Cons: "But then they deboarded the plane and everything went south fast. They didn't tell us what was happening or where to go or what to do. Instead we were directed to different service centers. We were told conflicting things. Sometimes they told us to exit the airport through passport control, but without any information on what to do next. They reopened the terminal but then redirected us to a service center. That center was overloaded and we ended up waiting in line for service/information for the entire day. Once I was near the service center they dissipated the line. They told us there was another service center in a different part of the airport and that this one we have waited for was closing. We went there and it was also closed instead they had beds without blankets or pillows limit the halls. Alia we were in line for hours before they offered any water or food. Food was really late. Information was the problem here. We were not told what we should do except to check with the service center. Eventually a few of us tried to get through passport control and check the service center out front. This worked much better. I was able to get a hotel and a standby ticket. That flight went much better but getting that far was a mess."

Pros: "I used to fly lufthansa for my europe travel for work about 15 years ago a lot and thought in recent years it may not have been as good but these flights made me appreciate Lufthansa anew. Crew extremely helpful and polite, always followed up to any requests. Instead of barking at us like United or American crew, they went out of their way to help my daughter get a makeshift icepack for some very painful bumps she got during our vacation. Crew also kept the bathrooms clean from time to time, which was a welcome relief for such a long flight. Desk staff/service desk also was helpful in directing us during the 5 hr layover to things at the airport itself that we could do. They also helped reprint the boarding pass and write down the baggage tags when security made me lose those by separating my wallet and boarding passes into mutliple bins."
Cons: "Phone service. When I tried to book my seats and meals, the lady kept getting things wrong, and ended up not getting me the seats I had specifically ended up asking for. So, when I arrived at the airport and printed my boarding cards, those were seats I did NOT want and all the service desks insisted that's what I asked for. No low carb meal option was surprising. Meal service sometimes felt like too close to each other else too far apart from snacks - didn't feel like we had enough time to digest and get some sleep, while at other times we were seeking out snacks.Overall good quality of food however."

Pros: "I sat in row 95, the first economy row behind Business Class on three upper level of the A380. Infinite leg room. Seat reclined more than usual in economy. Boarding was pretty good. Three gangways, one for First and Business, two for Economy. Crew was very friendly throughout"
Cons: "Seat was still very narrow. I had the whole low cal meal. The fruit for dessert was nice, if half frozen, but the meal was dry chicken breast with some veggies, with a dry chicken 'salad' as side"

Pros: "Friendly staff"
Cons: "In seat entertainment, better food."

Pros: "Flight from Marseille was delayed. Very tight connection time to make the SFO leg of the trip (30 minutes). A Lufthansa representative met us at the gate along with another passenger and took us via van to passport control and then to a terminal far away from the one we landed. She was courteous and efficient. We get to the gate in time to board."
Cons: "My seat was in row 56, second to last row. The temperature was very cold. I asked a flight attendant to make it a warmer. They tried but to no avail. The flight attendant mentioned that aircraft model (now 15 years old) has had that problem that has never been resolved. Solution was wearing a hat and several blankets. Not good for a 12 hour flight."

Pros: "The food and the entertainment system was great. Easy to check in from home and I was able to change to a seat I liked better. The flight was on time."
Cons: "The airplane was rather old, the boarding and deboarding took forever."

Pros: "A delay on our first leg (from Marseille to Munich) meant we missed our flight connection to SFO. Ok, these things happen. Lufthansa customer service in Munich was excellent--courteous and informative. We did not have to negotiate for lodging and other amenities while we waited for the next day's flight. Lufthansa provided for us with grace, including hotel, dinner, breakfast and the shuttle to and from the airport. The accommodations were excellent and we adjusted to our new departure time in comfort."

Pros: "Flight went well, the free entertainment was great, flight attendants came around on a regular basis with refreshments. The overall experience was good."
Cons: "For the most part, the flight attendants were great. But there were two in particular on my flight that could haves used some lessons in manners."

Pros: "Food was terrible"
Cons: "Toilets were not clean"

Pros: "The food"
Cons: "Was not offered a head set inlees it eas in thr blanket and pillow package. But was a nice flight snd srrvice. I injoyed the food."

Pros: "The crew were relaxed and nice."
Cons: "United Economy is very tight and uncomfortable. Flight was delayed and no one said why until I overheard a crew member say it was going to be 15 min for paperwork. Snacks were scant. Boarding was chaotic, but it was a pretty packed flight. Not enough seats in the board in area for a plane that big. Screen for movies was far away or small and not individualized like most planes."
