Cons: "Cabin kept very hot, very difficult to sleep. Seats were so-so comfortable"
Pros: "Orderly boarding process. Considerate reseating when bulkhead with extra legroom were not usable."

Cons: "The food was mediocre and the selection of movies was very limited."
Pros: "Great organization, very efficient"
Cons: "Bag fees were not made clear on Kayak or Swiss website, seats on Edelweiss A320 we’re spaced too close together for my legs, though was not a problem on the 777."
Cons: "I never made it on the flight. It was over booked, they switched me over... I'm still at the airport, missing two days of my vacation. Flights have been delayed from SFO, causing me to miss so many of the connecting flights..."

Pros: "Everything!"
Pros: "Great friendly crew. Efficient systems."
Cons: "Tight seats. Very little leg room."
Pros: "Flight was very smooth and on schedule."
Cons: "Seating in economy was very cramped (pitch felt like 77”) and food and entertainment nothing special. Somehow I had higher expectations for comfort and service, even in economy."
Cons: "Did NOT know ticket was economy light!!!! I WAS UPSET WE HAD TO PAY BAGGAGE FEE!!!!"
Pros: "Great cabin crew!"
Cons: "While waiting to board SFO-ZRH flight Swissair personnel walked around and randomly pulled out passengers from line to check luggage dimensions. Since manufacturers adhere to airline baggage standards, no violations were found during checks. This misguided effort only resulted in publicly humiliating Swissair customers. Boarding process was pure pandemonium...this was the first time in recent memory, where all coach passengers were invited to board at the same time! Very inefficient! Crowded seating in coach,with ten passengers sandwiched in across Boeing 767 aircraft. Competing airlines flying identical aircraft have nine across seatings Thin seat cushions cause leg cramps after a few hours."
Pros: "I was gratified to see that the 777 Boeing aircraft have now replaced the older Airbus aircraft..... This is my sixth time traveling to Switzerland from San Francisco on Swiss....Their service in my opinion remains excellent......The cabin crew was cheerful friendly yet remained very efficient at the same time... The food was very good, , The two meals that comes with one's Ticket still also comes with complimentary beverage service .... and even a warm moist towel is offered towards the end of the flight ... not bad for a seat in coach ...."
Cons: "I had no complaints except that there was a 40+ minute delay in receiving our checked baggage..... this could have been a problem With the airport ground crew at Zurich airport ....."
Cons: "2 hours delay!"
Pros: "The seats would recline too far so that people behind would get their range of motion uncomfortably limited."
Pros: "good flight didn’t have any problems"
Pros: "The Boeing 777-300ER is ether new and clean."
Cons: "Seating was super tight. Once the person in front of me declined their seat the screen of the inflight entertainment system was right in front of my nose (no, my nose is not particularly long). I’ll consider flying Lufthansa or United next time - even if It required a stopover in Frankfurt or Munich."
Pros: "Families with small children can board with first class passengers. The staff member who checked us in greeted my son by his name at the plane door!"
Cons: "Some flight attendants were not attentive to service."
Pros: "The seat is designed beautifully. Staff and crew incredibly nice."
Cons: "Movie and TV choices were so limited. You really need to add more options. I found only 1 movie I liked."
Cons: "Very tight seating in economy for a transcontinental flight"
Pros: "Food and service were good"
Cons: "Seats were terrible - way too small, too tight. No room for underseat placement of a backpack and feet. Sardine packing of economy passengers!"
Pros: "Entertainment was excellent and they made it a very comfortable flight."
Pros: "Enjoyed the service."
Pros: "entertainment selection"
Cons: "upgrade entertainment system, needs touch screen and screen wouldn't turn off completely. leg room and space under seat"

Cons: "Terrible plane ; no room , the most miserable flight we have ever been on"
Pros: "We were very pleased with our flight on Swiss Air."
Cons: "No plugs for USB chargers in economy. Entertainment units were broken."
Pros: "Enjoyed the food. On demand entertainment. Beverage service."
Cons: "Despite paying for extra leg room I somehow needed more. Not Swiss Airs fault, but I know better for next time."
Pros: "seat too tight"
Cons: "100% of our checked luggage was lost and two days into our one week biking trip in Sweden we have heard NOTHING from Swiss Air. No knowledge of where the four large bags are, no follow up and no help. Basically, we have been left with biking clothing and little hope that our bags will show up before we leave Sweden. Unacceptable and we will NEVER fly this airlines again."
Pros: "Good service... Quick boarding"
Cons: "Older plane, seats too narrow and short for 11hr flight. Bathrooms are TINY even by airline standards. Entertainment system has lots of choices but screens are low quality."
Pros: "Staff were nice"
Cons: "Very old plane. Had a big metal box at my feet, could not stretch out. Tv screens old and hard to watch. Food was pretty bleak too. Very disappointed."
Cons: "Old plane, hard uncomfortable seats, no wifi, rigid flight attendants, awful food, middle seat (after paying for premium seating) with two enormous guys on either side, fixed armrest, AC dripped on me most of the flight and was told nothing could be done, interminable."
Pros: "Great crew, and on time, of course: there Swiss!"
Cons: "Tech old and seats uncomfortable and plane loud."
Pros: "Stewards were great. The food was good and generous."
Cons: "Seat rows were too close together and seats were uncomfortable for the 11 hour flight."
Pros: "As usual, the food and entertainment were very good. Boarding was easy as we just lined up and entered the plane w/o any concern for group #'s, etc..."
Cons: "I was stuck in an aisle seat in the back of the plane where there was literally no leg room - there was a metal box (video equipment?) in the very narrow space underneath the seat in front of me. Luckily there was no one sitting in the middle seat so I could put my legs there. Also, when flying to Europe from the west coast I prefer flying to the east coast first and then taking a red eye."
Pros: "super nice crew-really friendly, accommodating, happy, all that sort of thing. really liked them and they're awesome!!"
Cons: "i am a regular sized woman, size 8, and a bit tall 5'9" and the seat felt wayyyy to small for me. couldn't put my hands naturally by my sides and the arm rests were too high to be comfortable, so i had to sit there with my shoulders held up the entire flight. was so sore afterwards!! also, the headphones barely worked (only one side, on the replacement as well!) and the entertainment system shut down twice."
Pros: "Jennifer - Appreciate the security and follow-up"
Cons: "Not the traveler will need to get boarding, crew, comfort, food and entertainment next week."
Pros: "Service was nice. Food was decent."
Cons: "The flight attendants did not have much in the way of personalities. Efficient, but no sparkle."
Pros: "Clean. Elegant. Modern. Very friendly. Food above average."
Cons: "It's always very hard to upgrade to business class. And the Swiss Miles & More website is not very user friendly to navigate"

Old plane. Zero leg room. Dour staff. Turn lighting on repeatedly on redeye - spend half the time making useless announcements. Impossible to sleep even if you were in 1st class.

Pros: "Yes"
Cons: "Delightful experience except at SFO checkin."
Pros: "A box was under my feet, not sure what it was. A part of plane! ATL - EZE uncomfortable Crew great in spite of ongoing turbulence!"
Cons: "Aircraft was too warm. Needed more air!"
Cons: "The entire time there was a clogged bathroom smell coming in waves. The crew was forgetful of requests. Not a pleasant flight."
Pros: "Check in person was very helpful in rerouting our flight."
Cons: "Our flight was delayed 3-1/2 hours. The gate crew booked us in another flight but did not issue a ticket, so after transferring to another terminal, we were sent back to the Delta terminal to be issued a ticket to a third airline since we already missed the second flight. Then, they lost our luggage"
Pros: "I liked the crew."
Cons: "I didn’t appreciate the women at the boarding counter. She had a very bad attitude and was not approachable."
Pros: "Quick boarding"
Cons: "More water offered by crew"
Cons: "The fact the the toilette was kitty cornered in the mid cabin bathroom is a joke on modern society."
Cons: "Better food and more water."
Cons: "Crew could be on time for work so the flights aren’t delayed"
Pros: "The Delta crew was great."
Cons: "Flight was delayed, for unkown reasons."
Cons: "Boarding was like a cattle call....my headrest was broken so couldn’t sleep upright but face down....seemed like a plane that large would have more bathrooms"
Cons: "The sits are uncomfortable"
Pros: "No delays..arrived early"
Cons: "Restrooms were dirty"
Pros: "Nice employees and service"
Cons: "Seat room"
Pros: "Nice Airbus plane. Due to thunderstorm in Dallas, pilot not able to leave DAL to come to fly the plane in LAX on time. We delayed around 45 minutes. Otherwise, crews were professional and efficient. Excellent movies choices."
Cons: "Boarding announcement in SFO was bad. No one can hear what the agent announced. Random sequence of boarding with confusion. In LAX, we supposed to go to a different terminal by a bus. There is no guidance out of gate to assist passengers that transfer to get on the right gate on the right bus. In AUS, there is not any announcement for luggage belt. An announcement would be helpful to new arrivals to this airport."
Pros: "Cheese plate"
Cons: "TheyCharge me $25 for my bag and I’m at Delta sky Miles older plus the American Express platinum card holder it’s supposed to not be charged"
Pros: "Entertainment"
Cons: "The plane was hot"
Pros: "The flight attendants were very kind and hoped to make up for the pilot’s negligence."
Cons: "Boarding was weird with a lack of overhead bins and then the pilot was inconsistent with updates to safety issues. We were delayed by an hour and twenty mins and then had to wait on the tarmac for another plane to leave the gate. Feels like I wasted two hours in limbo."
Pros: "Flight was great"
Cons: "The waiting area at gate 47 is a joke. Doesn't anyone care that it was filthy and had 10 seats for passenger waiting to board their flight?"
Pros: "The crew was very professional, hejpful and had good attitude towards the passengers. This made the flight easy and enjoyable."
Cons: "Call center tried moving us to later flight that was also delayed by 3 hrs despite telling us it was on time. Fortunately a gate agent moved us back to orig flight"
Pros: "I like Delta but this crew had such a shi**y attitude it was contagious. Yikes!"
Cons: "The gate staff and the flight staff. Rude"
Pros: "Call back service was best part."
Cons: "Booked ticket through venture card points. This meant that the email address and phone number to contact us in the event of changes was mediocre information. I was informed from Tripit that the flight was delayed, not by Delta. Reservation personnel took logical course of action to find new flight for connection that we could make because of delayed initial flight. I would recommend that they first see if there is an earlier initial flight that the customer could make, then look at finding later connecting flights. We found out about delay 8 hours prior, so we had plenty of time to get to the airport earlier. Total delay required me to take additional day off of work."
Pros: "Entertainment"
Cons: "Attendant probably trying to be funny"
Pros: "Sky Lounge at SFO and onboard entertainment"
Pros: "Once aboard, flight went without a hitch and flight crew was attentive"
Cons: "The inflight entertainment options need to be expanded - I've run out of movies that I want to watch!!!"
Pros: "Entertainment. Large overhead compartments. Clean."
Cons: "The temperature in the plane was too hot and made for a very uncomfortable flight. The individual air conditioner spewed out hot air. My kids and I took off as much clothing as possible and still remained hot. We were putting ice on our wrist to try to cool down! I sat with my hand against the window to capture some cool air. We were in Row 37. I am not sure if we were in a hot seat or if the other passengers experienced the same."
Pros: "The flight left anfd arrived on time"
Cons: "We were in "prefered". still the seats were very tight with little leg room. I am a 150 lb guy and cannot imaginer the discomfort of a large person."
Pros: "Flight schedule and the various flight options with regardss to the number of departure and return flights."
Cons: "Delta flight crew complacency and the lack of on board options. I flew first class and the food options were very limited. The crew also seem to have the attitude as though the passengers should be automatically understanding and satisfied. This was mostly on the return flight, an all male crew."
Pros: "On flight entertainment has improved greatly. There are so many choices to keep you entertained. I forgot how long I was on the plane."
Cons: "Plane food was not good. The crew were not as friendly, almost exhausted. There was one woman who was not sensitive or compassionate to my fellow seat mate. He was an older man who needed extra assistance. From the look of her face she didn't feel like helping him... as simple as helping him pour ice into his cup. Instead I helped my fellow neighbor. She might not feel comfortable helping a senior citizen but don't be so loud or make a face of disgust."
Pros: "They say us together (we had seats apart -- even though it stated our children are 4 & 1). They gave them wings and each an extra little snack. I felt they were supportive of us."
Cons: "Paying to check our bags!! We were forced to... too much stuff traveling with kids. It sucked to have to pay $50 when Alaska airlines saw we were struggling, they checked our carry one for free to ease our time in the airport!"
Pros: "Everything went smoothly."
Cons: "N/A"
Pros: "Comfort and boarding"
Cons: "Delay and food"
Pros: "Everything about the flight was great. We boarded and took off on time. I have no complaints."
Cons: "My seat wouldn't recline at all. I think it was broken. Not the end of the world, but a bit of a bummer as it was an overnight flight."
Pros: "Boarding was a breeze and the staff at Delta was nice and courteous along with being clear for boarding zone instructions. Haven't had a problem yet with Delta! Also the pilot was great at landing so it was not as jerky as some flights I have been on."
Cons: "No complaints!"
Pros: "As of April, they have free small meals. We had a turkey sandwich which was filling. Later came a snack, just enough to tide one over until finding dinner."
Cons: "Seats still cramped."
Pros: "The new Delta planes have great leg room for tall people even in coach."
Pros: "Delta was smart with boarding early once they realized everyone had cleared security. Flight took off on-time and arrived early. The crew was excellent and exuded energy although it was the end of the day."
Cons: "I ordered a special asian vegetarian meal and it was just plain horrible. I had to settle for the cookie. It's nice that they serve a complimentary meal on the red eye flight but the quality of the food was bad. Entertainment options were also limited although they had some recent box office entries from last year. The leg room also wasn't great but that's expected in economy I guess."
Pros: "Excellent trip. Provided ample food snacks and drinks."
Pros: "Flight very smooth.Just after landing,luggage pick up wait too long,almost after one hour later."
Pros: "Whoa, we flew Coach and had plenty of space! How marvelous to not be packed in; crew and passengers were wonderfully relaxed, and all went well despite turbulence on takeoff and landing. Great daytime flight experience with my toddler grandchild!"
Cons: "I tried to get a seat and it was so hard, i couldn't do an online check in and once at the airport, no one could help me."
Cons: "Boarding took too long - full plane and double seat booking changed 10 minutes early estimate to 20 minutes late"
Pros: "Quick boarding"
Cons: "The delta comport seats were not comfort seats were hardly comfortable and the leg room wasn't worth paying for."
Pros: "On time"
Pros: "I've never seen such a modern and easy to use entertainment system before. All the movies are complimentary."

Cons: "Free wifi"
Pros: "One on the plane, the flight was fantastic! Great service and food. Comfortable for a long-haul flight. Very modern aircraft with nice entertainment system. Overall great experience."
Cons: "Scheduling! We were 4 hours delayed after I had already had a flight cancelled that day. And this 4-hr delay caused me to miss my connection. Turkish did take good care of me in Istanbul, though it was a very slow process to get a hotel with them. Also, my bags missed the connection somehow."
Cons: "The flight was delayed by 4 hours but Turkish airlines inisisted that I had to be at the airport and checked in at the scheduled time and then wait at the airport for that whole time."
Cons: "The aircraft arrived late in Istanbul for the connecting flight to Egypt causing us to miss out flight which made us wait 5+ hours in the airport which was a huge inconvenience."
Pros: "Food was excellent! And plenty of it"
Cons: "Temperature way too warm"
Cons: "the boarding was delayed and i missed my connection flight and have to stay 8 hours for another flight."
Pros: "The food was great for airline food."
Cons: "I didn’t get upgraded to 1st class. ☺️"

Cons: "Gate experience at IST was sub par"
Pros: "The recline and comfort of the seat is good, and the map and entertainment system is OK."
Cons: "The flight was delayed, then we sat in the airplane for an hour before we took off, with kids screaming and the cabin at seemingly sauna temperatures. Once we took off, drinks weren't even served until 2 hours after take-off (for a scheduled 6:15pm departure - actual was more like 7:45pm). Maybe it was due to some light turbulence along the way or something, but they should tell people that is the problem and the reason they are not serving food and drinks, if that is the case."
Pros: "Friendly, charming and welcoming staff."
Pros: "Everything was fine"
Pros: "The flight was for the most part quite comfortable"
Cons: "The person sitting behind me (she could not get comfortable and kept jarring my seat) and the baby crying two rows ahead of \me"
Pros: "The amount of food and drinks we got was perfect, the movies, shows and other entertainment options were plenty and they had a great selection, and the sleep kit (slippers, socks, lip balm, etc) was very much appreciated and helpful. The staff were nice and professional."
Pros: "Friendly staff,"
Cons: "My infotainment center was broken for the entire 13 hour ride. Luckily I had my phone but it would have been nice to have the expected entertainment options. The service carts only came through twice leaving a many hour gap with no drink or food service."
Pros: "Everything was great, thank you for your service."
Cons: "NA"
Pros: "N/A"
Cons: "Connecting both flights would be good"
Pros: "Entertainment was OK boarding was a good comfortable sitting."
Cons: "I did not have an option to order kosher meal when I did my online check-in so I called customer service and the lady on the line barely spoke English and even though I warder kosher meal and verified it with her when I go to the plane the crew told me they don't have a kosher meal for me. The crew was unwilling to help me find something else to eat and they were very rude. I am very disappointed of their customer service standards. I will not use Turkish Airlines again."
Pros: "Friendly staff, decent meals, comfortable seating"
Cons: "Istanbul airport- needs major refurbishment"
Pros: "Food was too complicated and saucy. Simple dishes preferred. My fork had chunks of fried on food (was dirty) snd unusable. Interior of plane was tired."
Cons: "LOts of water available. I like the menu being given at beginning of flight as one could plan the hours."
Pros: "Being able to stretch out and get some real rest makes a huge difference for me when trying to cope with time zone change west coast to Europe. Overall great experience"
Pros: "Flight attendants were not helpful or friendly."
Cons: "Flight attendants were not helpful or friendly."
Pros: "After your bags are delayed 3 days, it's hard to like anything about an airline."
Cons: "Tracking my luggage was a nightmare. No one had any idea where it was for 3 days. When my bag finally arrived, the exterior was severely damaged. Also, the fight crew is rude and unfriendly. If I can help it, I will never fly Turkish Airlines again."
Pros: "Everything"
Cons: "nothing"
Pros: "Staff are EXCELLENT"
Cons: "Internet was spotty."
Pros: "Great food, great service and a wonderful experience in business class compared with most of the big European airlines. Will definitely fly again Turkish Airlines!"
Cons: "The business lounge in Istanbul was a great facility, but a little bit of upkeep will be a plus."
Cons: "This 13 hours and 5 minutes flight was extremely hot. Regardless of how many times we've asked the flight attendants to make it cooler for us, nothing changed. By the time, we get off my shirt was soaking wet. Imagine flying for so long under these conditions. What an horrible customer service!"
Cons: "Departure is 4 hours late. Missed connecting flight at Istanbul. Asked us to pay for Visa to stay in hotel. Did not have money. Also forgot to take Credit card from USA. As per the rule Airlines has to pay for Visa. They never paid. Asked us to pay. Totally harassment. Never book Turkish Airlines in my remaining whole life. Also will this incident to all my friends after going back to USA. Very very bad experience. Sat down 24 hours at Airport without food and sleep. Mostly will file a case against Airlines."
Pros: "Worst airline ever"
Cons: "Worst airline ever."
Cons: "My first time flying with Turkish probably my last. Too many delays, first from SF to Istanbul and then the worse part no one was able to tell me from which gate my flight to TLV, I received at least 6 emails from you saying a different gate each time and we had a delay almost two hours in Istanbul. Because of all the delays I missed a few important phone conferences regarding my business. Unprofessional service! if I was running my business the same way I had no business! Not going to do this mistake again!"
Pros: "Crews attitude, professional behavior"
Cons: "Not enough leg room in economy class"
Pros: "It is just superb"
Pros: "Giving the kids a gift"
Cons: "Worker the didn't smile and not helping very well and getting angry when I asked for help or even they didn't know how to serve people. Airline to bad 2 airlines I go with them is very hot inside. Having bad AC. Thanks"
Pros: "Low prices & generally good service and entertainment"
Cons: "This airline used to be excellent. Now, the prices have been going up and the standards down. Service not as good, food not as tasty, plentiful and varied, crew not as warm and attentive. Instabul airport was the usual chaos, which does not add to the experience for transfers. Also: boarding started late and of course was not done and time and since we lost our slot we were further delayed taking off. That made the transfer time even less and the situation more stressful."
Pros: "Checkin agent was very friendly and helpful."
Cons: "The food options were exhausted by the time service reached my seat; so had to eat whatever is available, which is still good."
Cons: "I had two checked baggage a and o my 1 was delivered. I have reported this at the airport and have been following up with their customer service many times but no information is yet provided after days."
Pros: "Movie selection and food was good"
Cons: "The flight departed late and we had to run like psychos to our connecting gate to Athens... We barely made it."
Pros: "Excellent"
Cons: "Very good experience on a nonstop from San Francisco to Istanbul & on to Thessaloniki. Very friendly professional staff. Good food. Charge outlets at the seats. Big choice of free movies. Istanbul airport is very busy. We had delays arriving and leaving for the connection."
Pros: "the entertainment was good - nice staff - the interval of refreshments was good. the red wine was Ok too!"
Cons: "the bathrooms could be cleaned every few hours with so many visiting it for 13 hours.... it really becomes a bacteria hot spot ...!"
Pros: "Very kind and helpful crew members Lots of stuff provided: drinks, food, kits etc"
Pros: "Staff are very friendly and deliver very good service. Refilling of water could be better. Seat was very comfortable and it comfortable for sleeping when it is flat. The seat cover improves sleeping quality. Dinner was well prepared and tasty. Skip the fried eggs for breakfast - it is great that they offer them, but they don't come out well."
Pros: "We purchased coach tickets and were surprised at how nicely we were treated!! A very classy operation!"
Pros: "Excellent trip! Great pilots, good service, and a complementary hotel room for an over night layover ( must have turkish visa). I would agree with the statement that they are one of the best airlines in Europe."
Cons: "No ability to upgrade seat at airport. I am not sure if upgrading is even possible. There were plenty of open comfort and business class seats that could have made additional money for the airline."
Pros: "The seat was good"
Cons: "The crew was not at all good, I had to call them so many times for one thing, not at all managed well"
Pros: "Sitting in a metal tube flying at 40,000 feet with 300 other personalities has its challenges. Turkish Airlines' staff managed this with excellent care. The smallest things begin to matter; the comfort of the aircraft, quality of food and drinks, the frequency and availability of service, and above all conveying the sense of safety. Every member of this company, from the staff at the counter to the flight attendants, to the pilot seem to really embrace customer service."
Pros: "The flight was delayed for 4 hours then cancelled. Then we all stood in line for another 4 hours to book a different flight. However the next day when I came to check in for my new flight with united. They said Turkish airline had never sent the flight transfer. This happened to many other customers. Once again we all had to run around to find help but Turkish was severely understaffed and ill prepared. Overall a terrible experience."
Cons: "There was nothing I didn't like"
Cons: "Didn't have a dinner option available.......ran out of chicken for dinner"
Pros: "Everything"

Please return all my money u just sucks

Cons: "Food"
Pros: "Very helpful crew. Quick boarding process."
Cons: "Not much leg room, or space in seats."
Cons: "Delayed over 4 hrs, missed connecting flight as we were supposed to meet with in Frankfurt. Spent hrs getting a new itinerary, one bag never showed up in Nairobi."
Pros: "Crew was a top notch, very focused and carrying. I am loyal lufthansa fan and been flying with them with more than 20 years."
Cons: "Guys, we need to do something with these outdated business class seats, infotainment system. Omg, last century, movie selection bottom poor :( We are always playing catch up game in terms of interior. How long it took you to offer padding & decent blankets in business."
Pros: "The crew was the best"
Pros: "Convenient seats in A-380"
Cons: "Drinks were good, but food was bad"
Pros: "delay of 2hours caused by disturbed person poor crew reaction no info to other passengers"
Cons: "I travelled economy and found the seats not very enabling for big and tall folks as myself ! Other than that I highly recommend flying Lufthansa"
Pros: "The crew."
Cons: "The airplane arrived over 45 minutes late."
Pros: "The crew, the airplane, and the drinks were great."
Cons: "The food was just ok."
Cons: "Our flight was cancelled by the airlines due to mechanical failure. Told us to go home and wait for email on what to do. No compensation"
Pros: "Check in was easy, flight was smooth, had good seats with legroom. Liked receiving updates on phone."
Cons: "United connection in San Francisco was over 2 hours late, didn't arrive home until 2:30AM."
Pros: "I'm 86 years old. They took me in a wheel chair past security and allowed me to preboard. The staff is very helful."
Pros: "Crew was very nice and professional. We arrived early"
Cons: "Food was disappointing as was the wine. I am not a large person but I found the business class “bed” pretty narrow and uncomfortable."
Pros: "The plane was very clean and I appreciated when the crew asked passengers have their seats in a normal upright position during meal times as there is very little space when the seats are reclined. We can hardly get out of our seats when other passengers need to go to the restrooms."
Cons: "The crew was rather cold; I got the feeling they were doing their jobs but not in a warm and customer friendly oriented way, may be because I was in Economy. I was surprised by the lack of space in economy for such a long Haul flight in an A 380."
Pros: "I liked the comfort of the seats and the spaciousness of the area allowing for standing out of the way. The service was exceptional and the food on this flight was very good. Entertainment was also very good."
Cons: "My only suggestion would be if the crew would inquire if you've ever flown either with Lufthansa or specifically business Class and just give tips if needed. Other than that, on this leg of our journey we had no complaints."
Pros: "Great crew, great flight, food and drinks was awesome"
Cons: "I don't like the fact that I can't choose my seat from earlier because I a big girl and I like to set in the emergency exist seats so I'm not crush up in the middle seat not comfortable and long flight like that lots of pain at the end of the flight"
Cons: "delayed by 1.5 hrs due to computer issue with landing grear, missed connecting flight from Munich to Stuttgart, had to wait an additional two hours in Munich to catch a later flight to Stuttgart"
Pros: "I liked the seats, the space for our legs and the crew members"
Pros: "Crew was nice."
Cons: "This was an emergency trip to see my mother who was in the hospital. The flight was delayed so I had no option but to board the next day since I wouldn't be able to make it to the connecting flight in Frankfurt. They couldn't give me another connecting flight since it was all full. Because I booked my ticket only hours before my flight, they said it might not be possible to fulfil my meal request since there's a 24 hours cut off. However, now I had to cone back to the airport and take the next days flight which gave the airline more than 24 hours from my original meal request. I still did not get the meal I requested, the crew didn't know about it and didn't have any to spare. This was my first time flying Lufthansa, I probably won't try it again."
Cons: "Delayed in Munich an hour late"
Cons: "Lufthansa lost 6 of our bags and left us with no information or compensation. I sent them emails but there is no response from customer service. Costed us $500 to buy things on emergency basis for our family and they delivered the bags after 2 days. This was very unprofessional and Lufthansa has to pay for it. Can you please help. Next time we will certainly have to avoid The airline as their gate transfer in Frankfurt is horrible with very rude security staff who has no interest helping our family to board the flight on tight connection. Instead the person decided to go on his break right when we were at the X-ray screening. How rude and unthoughtful."
Cons: "I haven’t received my luggage and I have been in Mumbai for almost 3 days!!! I have to buy new clothes and plenty of toiletries, I have only had 1 phone call from the airline to tell me my bags never left SFO!!! Wtf!"
Pros: "Friendly crew. Flight left on time"
Pros: "All of it"
Cons: "Nothing"
Pros: "The entertainment was good."
Cons: "Many things. Starting from the online/mobile check in process via United airlines. I was not given any other option but to check in through the United website. On that website I was not allowed to check in for my Lufthansa flights and i was stuck with seats I did not want in my 2 long intercontinental flights. This has happened before. Lufthansa has no option to check in online if my first flight leg is united. This is a very big drawback and also the reason I would not prefer to fly Lufthansa again. United is bringing the quality down."
Pros: "Gave us snacks when flight was delayed"
Cons: "Flight was delayed Entertainment app didn't work"
Pros: "The crew were very friendly and I liked that they always kept us hydrated with drinks. Before I even left on the trip I called the airlines several time with so many questions and the staff that I talked to each time were so friendly and helpful with all the questions that I had."
Cons: "The only thing I didn't like is that the boarding process was different than what I was used to. I usually board by zones and this time it was more of a everyone got up at the same time and everyone rushed to the front of the lines and some people would push me out of the way to get in front. ( even though we all had assigned seating) Second thing was that I had asked for a wheelchair for my mom and I had seen one waiting outside and was about to walk up to it but another person was limping up to it and put her stuff down on it so I didn't know if it was for my mom or her. I didn't have the heart to go up and make her move if the wheelchair was for my mom so we ended up walking the whole way to customs. I felt bad for my mom afterwards because her knees ended up hurting by the time we got to customs. I would suggest holding up signs of individual names for who the wheelchair is for. Other than that everything was great"
Cons: "Was delayed in a connection and missed flight. No offer or help provided to get me and children on another flight without charging me ~$9000 for another flight. Paid out of pocket for another airline. Cannot believe the extortion and lack of service provided!"
Cons: "No special dish for kids food or atleast wasn't offered on the flight to us"
Cons: "I called the airline and paid for a specific ticket so I could have an aisle seat. They confirmed it was an aisle but Inhad 30F which is a window seat! I'll be calling Lufthansa for a refund. p"
Pros: "I really enjoyed my flight with Lufthansa. My gluten free meals were very good and the service was excellent!"
Cons: "It would be nice to be able to reserve seats ahead of time without charge"
Pros: "a good place e excellent crew"
Cons: "the plane is arrived over time and I less the fly to turin"
Pros: "I have ordered the salmon fish dinne and the fish was totally overlooked, dry and tough. I could not swallow the fish and ate the tiny bread roll only. The second was breakfast wigh tasteless scrambled egg and mushroom and spinach. Both serving sizes were really small with just one side dish of fruits. I was hungry the whole 10 hours flight."
Cons: "Changed the chef or the vendors who supplied the meals."
Pros: "Flight Attendants were Excellent. Friendly, attentive, and caring! Thank You Very Much."
Cons: "Lufthansa changed our seats, splitting up my wife and I, after confirming they were together. Thank you to the Flight Attendant who reseated us together but "you know what" to the person that screwed up the seats in the first place. Also the on-line check in process was extremely poor, maybe "bad" is a better word."
Pros: "Service was good, the airplane was good also"
Cons: "This time we experienced a strong turbulence. It would be more helpful if the crew gave updates about the situation more often, was really scary. Also, the food was not good at all...."
Cons: "The flight never took off. We had to wait 6 hours in line, and they still couldn't rebook many of us. When I was finally rebooked on a Swiss Air flight, the flight was invalid, Swiss didn't accept it. I was send to various different lines, and they didn't even understand what my problem was. Finally after spending 2 whole days at the San Francisco airport, I could take off with a 30 hour delay. The Swiss Air flight was wonderful."
Pros: "The flight itself was fine."
Cons: "Chaotic boarding process and tarmac delays consumed the already inadequate prospective layover in Chicago."
Pros: "- crew was nice - overall flight was smooth"
Cons: "- not too unexpectedly, food was small - bring something warm to wear, as at some point temps can be real cold... - wish the boarding process was slightly more logical and have people with seats in the back of the plane go first"
Pros: "Good in-seat entertainment"
Cons: "Uncomfortable seats Mediocre Food"
Cons: "1 After long stand the line when i want to check in my Luggage i got shocking news According to checkin counter lady said Flight delay more than 2hours and can be 3hours no body knows how long will be delay, she recommended me to go from San Francisco to san jose airport to get another flight. it's time Enough she said , that time about 1pm, i am lucky that i arrived SF airport 3hours in advance so that i could manage to catch up another flight at the san jose airport, i had to go san jose airport from San Francisco by Taxi and the cost was 170usd because driver says over 50mils far a way i need to pay 50% more, i have a alot import meeting in germany, meeting schedule could be mess i was really shocking, how can i get back Taxi fee usd170??? 2. regards to Crew., one Passenger was collecting his handy carry luggage at Cabinet and he forgot to close Cabinet cover after he collected and it was opened that time one flight crew passing by to final check up before landing but don't see that cabinet door open, so one of passenger talk to her to close the Cabinet door, also handy carry luggage after used the passenger should Keep Under the chair for safety but even passenger keept (put) in her beside empty seat, the Crew don't say anything, it was many people keept in next empty seat area. According to rull must keep it under seat, but crew don't say anything I was very very surprised. it's very Dangerous to everybody people may hurt , i was very Scared and nervous. 3. in the dark room passenger can't see or feels that behind them whether crew come or not (passing by or not) Crew passing by and hit passenger but without saying sorry and just go a way. it's impossible... 4. i was standing at Exit door and look at the outside but same time crew came and said to me not friendly and without smile "Excuse me" and i go a way, i saw she crew want to put something inside at dress room. what i want to say the crew could be more nice and smiley face to passenger or could be nice can be wait 5 seconds but was really the way of tone is Racist, this is what i felt, really bad."
Pros: "At a time when airlines are treating a plane like a flying bus, it's heartening to see Lufthansa's attention to detail for its customers both in terms of ontime departure, arrival and inflight hospitality is second to none."
Pros: "Latest movies few included"
Cons: "The space is so small. For 11plus hours my body could not move. I never had knee problem but they were so sore. My feet and body got extremely tight mid way in the flight. This is my first and last flight in your airlines."
Cons: "Food was lousy. I have not flown L for sometime, but the food was lousy. I don't remember it being this bad previously. They ran out of rice and chicken...and served me beef... The chicken was on the bone, instead of being off the bone...so harder to eat in small space."
Pros: "Everything was ok"
Cons: "Food was very bad"
Cons: "the monitor at my seat did not work and I could not watch any movie. Everything else was fine."
Pros: "The plane stewardesses were actually really efficient (German style). Because of being on the waiting list to get on the plane I couldn't get a seat next to my partner so they did the biggest math exercise to put us together. Props to them"
Cons: "The flight overbooked (I still don't understand this concept, since is basically selling twice the same seat, right? Is that even legal?) Also the system was down, so no check-in online = the biggest line at the airport, it took me more than 1 hour to check-in and drop my luggage, all to get there and the ground force lady (the rudest person alive) tell me that I had no seat available, that she was going to put me on the waiting list... WHAT? I bought my ticket already, waiting list? Well, to say that I highly doubt that I'll book with Lufthansa again."
Pros: "first time in the new economy plus, was a pretty good experience-- food comfort, etc."

Cons: "The boarding process was chaotic. The passengers in the first boarding group had to fight through the crowd because there were no boarding lanes."
Cons: "When a bought my ticket, I had asked in the office about WiFi. They told me that you have WiFi on the plane. I had checked this information on KLM.com and saw the same, that you have WiFi. This was the reason, why a chose KLM! Then I tried to connected on board but I couldn’t! WiFi was not available. Crew told me that they don’t know anything about it! I was disappointed and angry."

Cons: "suitcase didn't turn up, although connection was quite tight"
Pros: "Great crew service. Among the best ever."
