Pros: "Nothing. I was sold a ticket for 709 dollars and wasn’t told I couldn’t get on until showing up to the gate. Therefore I had to spend 1000 more dollars to book another ticket because budget air wouldn’t change or refund the flight."
Cons: "Not selling a ticket with a layover where someone with a US passport cannot travel through at the moment. Be more forthcoming."

Pros: "Nothing. I was sold a ticket for 709 dollars and wasn’t told I couldn’t get on until showing up to the gate. Therefore I had to spend 1000 more dollars to book another ticket because budget air wouldn’t change or refund the flight."
Cons: "Not selling a ticket with a layover where someone with a US passport cannot travel through at the moment. Be more forthcoming."
Cons: "I fell sick and my doctor advised against flying. Tried calling Swiss Air and JustFly.com: 6 calls back and forth and 7 hours on hold, no help. Finally got advised on driving to the airport to make the flight change at the Swiss Air counter at O’Hare. The representative told me to bring a note from doctor to switch flights. I did the next day. The same representative looked me in the eye after advising the day before and said there’s nothing she could do. Why make an elderly sick person drive to the airport again if you know already you cannot help??Absolutely terrible experience, no help from the airline or travel agency. Total loss of the full price of the ticket."
Pros: "Great smooth flight, crew were friendly and many movies and shoes to choose from."
Cons: "Seats are tight and not much leg room for the unfortunate ones who fly Economy class. Food was ok."
Pros: "Crew was great. Peppy and kind."
Cons: "ORD ZRH seats extremely crowded. Wished for comfy Star Alliance seats for that flight which we did enjoy from ZRH BUD"
Pros: "The boarding process was easy"
Cons: "Some of the crew members were rude and inconsiderate - if you see that someone is sleeping, you don’t stand at their seat and lean on it and shake it while you’re waiting to give the security demo before take off."
Pros: "Movies"
Cons: "Crew was rude to passengers. One passenger asked for extra bread and crew arrogantly commented , we dont give but ok take one."
Pros: "Coach seats were comfortable but if the person in front of you reclines, your video screen will be inches from your face and it becomes difficult to get out of your seat."
Cons: "Crew was not particularly friendly....almost downright rude at times"
Cons: "Only two options for dinner is very few options."
Pros: "The inflight entertainment was great and helped to pass the time. The food was good for airline food."
Cons: "The flight staff was just okay - they could have been friendlier. The seat cushions seemed old - they were comfortable enough for sitting but not comfortable to sleep."
Pros: "Everything was just dandy!"
Pros: "Amazing food, There were pillows, blankets and earbuds on every seat. Really a great flight overall and I would fly with them again."
Cons: "The only minor complaint was that the seats are so small that when the person in front of you reclines, you literally can’t get out of your seat."
Pros: "Some of the best airplane food I’ve had."
Pros: "Crew was attentive to passenger needs in a quiet way: without fanfare, did all possible to make it a pleasant, comfortable trip. In fact, went out of their way to get me a wheelchair ride to next flight, which I dearly needed"
Cons: "First flight was delayed due to circumstances outside of airline’s control. They managed to get us there and help me with wheelchair, etc to make flight. Great service and kindness"
Cons: "Chose the option with Swiss because it showed that a checked bag was included. Got to the airport and was told to pay up for each checked bag. Great start to the trip."
Pros: "Everyone was friendly, pleasant and very helpful. Upon arrival in Delhi our suitcase handle was broken."
Cons: "Leg room was really bad in economy and the only upgrade option was to business for $10,000 so of course not affordable for the average person."
Cons: "Food is bad"
Pros: "Boarding was smooth"
Cons: "The aircraft was horrible No space at all even after paying for a better seat"
Cons: "I’m a small person & your seating is cramped & uncomfortable!"
Pros: "The entire process from boarding in Chicago until arrival in Athens was very smooth."
Pros: "Great airline overall!"
Cons: "No leg room due to the airplane box under the seat in front of me. Very difficult to straighten legs out, difficult to get comfortable."
Cons: "Almost missed my third plane, too."
Pros: "Online check-in was easy, boarding was smooth, and time on the flight seemed to go by quickly. Seats were a little too close together in economy to fully relax but that's the nature of economy seating. The dinner was very tasty, crew was friendly."
Cons: "My seat-back entertainment system did not work, but I had not planned to use it anyway. For the other three members of my family it did work, but not very well. Fortunately they had other options they brought with them."
Pros: "On time flight"
Cons: "Are the seats getting smaller or am I getting bigger?"
Pros: "Fast flight and crew was amazing."
Cons: "Seats are terrible. Food is just ok, could me better, I remember 2012 when I was flying first time with Swiss (same route), food was excellent and seats were much more comfortable. I’m thinking to get back on Turkish Airlines although the trip is much longer, they are much better in both above mentioned segments."
Pros: "The flight was perfect until we hit horrible turbulence. 1 out of every 4 people was throwing up. We had to redirect to Milan."
Cons: "Swiss air is completely inept at handling a very normal reroute due to weather. 200 displaced people are standing in line. I’ve been here 5 hours and have not heard a word of announcement from them, our questions are rudely thwarted, and they continue to take half-an-hour to an hour per person with uncertain results. Give use new flights or a hotel."
Pros: "I am a frequent flyer with swiss airline. Amazing crew, boarding, taking off and landing is on time if not a little earlier. However, I was quite disappointed with the enertainment package and food."
Cons: "I am a frequent flyer with swiss airline. Amazing crew, boarding, taking off and landing is on time if not a little earlier. However, I was quite disappointed with the enertainment package and food."
Pros: "Flight crew, food, and seatback entertainment system (with USB charging port) were all great."
Cons: "The seats were uncomfortable and way to close. When the person in front of me leaned their seat back, I was forced to do the same. It was nearly impossible to eat. If you had a hint of claustrophobia, you would never make this entire trip without going nuts. I noticed that many of the middle seats were unoccupied, while my family and I were crammed into four seats side-by-side. If we had empty seats between us the flight would have been bearable."
Pros: "Great service and friendly staff! Also great food!"
Cons: "There's nothing I didn't like :)"
Pros: "Most everything about the process."
Cons: "Person in front reclined chair fully and left virtually no room for sitting!"
Pros: "very professional crew, clean cabin, interesting choice of documentaries"
Cons: "it would have been nice to see a hostess walk through with water every hour, of so why is there no world news in your tv selection?"
Pros: "The flight attendants seemed very courteous, but unable to do anything about the situation."
Cons: "We had a family of four sitting behind us. The father yelled all the time. They took up four overhead bins and he was frequently up and down getting things out of the bins. His very hairy large belly was touching my daughters head every time. He and his children punched the backs of our seats on a regular basis. My back was in constant pain and I was unable to do very many things due to the back pain during my "vacation", The flight attendants had to remind the parents that their children could not stand on the seats during takeoff or crawl around under the seats. No ability to change seats or I would have. I didn't have a problem with the other children on the flight, when they were crying their parents tried to do something. However these people brought playdough for their child to roll out or punch on the seat tray and all they did was constantly yell loudly at their children, Well not about the kicking, punching, or crawling around. Just yell in general at them."
Pros: "On time and friendly service"
Cons: "Poor selection of films, cramped seats and mediocre dinner"
Pros: "Airline services and great time scheduling"
Cons: "Upon arriving to Chicago airport the Chicago airport couldn't get passengers off the plane due to mechanical issue"
Pros: "I like the space in business class and the staff were really nice"
Cons: "The seats were not comfortable, they ran out of scotch (single malt) and I only had 1 drink"
Cons: "Airline lost my flight, no explanation and or apology. Seats were terrible could not move when seat in front was reclined. No economy plus, no reciprocal consideration for gold status on star alliance except for one checked bag free. I will never fly Swiss again"
Cons: "They lost my bag and after 24 hours, still no word on whether it's been located."
Pros: "Very prompt and courteus"
Cons: "Baggage missing for three days. Communication poor."
Pros: "Crew was great! Boarded quickly! Alot of movies to watch!"
Pros: "Very friendly staff, a wide variety of entertainment options."
Cons: "I'm a pretty small person (5'4 and 110 pounds) and it was very hard for me to get comfortable. Not that you'd expect much out of an economy class seat."
Cons: "Not. Lot of room for legs. Slection of movies very poor. Very old movies mostly"
Pros: "Flight attendants were friendly, and also very skilled so that their service was unobtrusive, graceful, and helpful. They took great care to get people what they wanted, and I saw them fulfill a few special requests from the people around me politely and quickly. The entertainment selections were good. The variety of interesting musical selections allowed me to go the whole flight without running down the battery on any of my own musical devices. The seat space was comfortable, especially compared to domestic flights I've taken for the last 10 years. The enforcement of carry-on luggage rules meant the overhead compartments were sufficient for what was brought aboard and people weren't filling the foot-space with bags."
Pros: "Crew and flight service are excellent top notch. Also they are very friendly and helpful. Make flight enjoyable."
Cons: "Seats are too close together in coach, very cramped and uncomfortable if you are a tall or large person."
Pros: "Good entertainment"
Cons: "Couldn't control the airflow at your seat."
Pros: "Seats very confortabile"
Pros: "The flight crew were friendly and helpful. The food served on our flight to Zurich was delicious. We loved the big movie selection which helped pass the time."
Cons: "The leg room was terrible on this plane. If anyone reclined their seats, you were trapped and could barely get out of the row to get up or go to the bathroom. Boarding was a bit like herding cats and everyone was jammed up trying to get on without any orderly direction."
Pros: "Our attendant was very nice with a great attitude."
Cons: "Luggage line in Zurich at airplane"
Pros: "Great flight all together."
Pros: "More space with a window seat than I am used to. Shoulder didn't even touch the side of the plan. Loaded the back of the plan first after premium and those needing extra time."
Cons: "By the time they got to me I only had one choice for the dinner meal. No restroom in the back of the plane so I got stuck waiting for the cart to come all the way down the aisle before I could go to use it."
Pros: "Flight boarding was quick and fast and food was great."
Cons: "Seats had no room and if someone in front reclined the tv was right in your face. Also what happen to having individual fans above. It was so hot I felt sick the whole way and when we pushed the call button no one came had to flag down an flight attendant walking by. We had to ask three more times to get the heat down. Overall it was okay."

They made us check carry ons despite the entire aircraft overhead space being empty

Pros: "Flight canceled without notification"
Pros: "Trip was ok"
Cons: "The flight was delayed 1 hour"
Cons: "Given we left at 7:15 am, I would’ve liked some food options instead of biscuits and peanuts"
Pros: "I had heard about limited food options during covid flights but everything was tasty and generous. I always appreciate it when my initial flight books my check-in to my final stop and gives me all my boarding passes at once and Delta did just that. They were also really good at communicating updates like changes to the gate."
Cons: "People should just be prepared to be asked more questions than usual. It can definitely make you feel nervous but just remember that the new covid restrictions are stressful for flight staff just as much as they are stressful for you. Be cooperative and honest and you shouldn't have any problems."
Pros: "Kosher snacks! Thank you. Screens and outlets at every seat. Safe, controlled Covid protocols including de-boarding. Excellent!"

Pros: "Short lines"
Cons: "Seating arrangements"
Cons: "The carrots were hard and the bread was cold."
Pros: "Comfortable plane due to few passengers"
Cons: "7 hour delay after flight postponed."
Cons: "I would ask that the gate does not share in detail reason for delay in seat assignment is related to getting a family sitting together when the basic rules should apply unilaterally."
Pros: "Got to my destination without any issues"
Cons: "Seats/seating area are too small, and I'm not a big person."
Pros: "All good."
Cons: "Price"
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: "Seat assignment for me and my traveling companion was done at gate. We had to sit in 2 different rows."

Pros: "Flight attendant in first class was amazing."
Pros: "The boarding was fast and very well handled."
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 flight attendants were very pleasant & efficient. They only served snacks on this short flight but were very good at ensuring everyone had at least one or more beverages. 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: "Snacks, cleanliness and crew"
Cons: "N/A"
Pros: "Nothing"
Cons: "They take them forever to find me another fly ,make miss my other fly, my work my time and my sleep"
Pros: "I was with my friend"
Cons: "Delayed 12+ hours"
Pros: "We had a 2 1/2 delay due to mechanical issues but the crews, flight and ground, did a great job. Thanks."
Pros: "Staff were friendly and boarding was and getting off was easy because flight was super empty. Timeliness was appreciated too."
Cons: "Seats don't recline far enough."
Pros: "I was given a complimentary upgrade."
Cons: "It takes time and worries to find the air train and Aeroflot registration."
Pros: "I needed to run real fast to the connection flight and gladly got there on time."
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."
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."
Cons: "Plane was sat broken at gate and needed part to be flown in. 150 minutes delayed. Not acceptable."
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 flight went very smooth including boarding, transferring at Istanbul. The infotainment system was helpful in a way that you could see the real time camera feed of the ground and runway."
Cons: "Fewer passengers on board. I know it’s about profits and financial feasibility, however listening to a prerecorded message about 1.5 social distancing while being boarded 20 cm from 2 passengers undermines the whole thing, isn’t it?"
Pros: "Lady “Setora” at the check-in was amazing. Very nice, kind and helpful person."
Cons: "Food service .. we where very hungry and thirsty during the flight. They barely give you some snacks ."
Cons: "This was my first time with Turkish airline , the airbus from Chicago to İstanbul was quite old and seats were not comfortable while the plan form İstanbul to Islamabad was perfect . Thank you Turkish airline"
Pros: "amazing"
Cons: "nothing"
Cons: "No coffee no tea. Disgusting."
Cons: "Foddd no gud"
Pros: "The boarding, comfort and crew were excellent. Everything is very organized and professional."
Cons: "I had a 12 hour layover in Istanbul. The hotel was great and I appreciated the good food and rest. However, it took nearly an hour each way to the hotel. I think it would be great if Istanbul airways cooperated with the Yotel so transit passengers could stay in the airport. They helped me to get a visa and they say it will be reimbursed, but all of those things took time when I was so exhausted after a long flight. Overall, it was wonderful to have that opportunity to rest and shower on a long wait, but it would be even better if it was closer and it was clear ahead of time that a visa would be needed."
Pros: "Convenience"
Pros: "The first trip from Chicago to Istanbul they given us the first chair with bed for baby But the next trip they not"
Pros: "Everything."
Cons: "Nothing."
Pros: "Great food options, very tasty. Crew was attentive, polite and professional."
Pros: "Everything with the airline was just fine. I’m overall very happy with the flight."
Cons: "The only thing that really made the flight not so pleasant were the really bad smelling passengers on board. People, please, take a shower before boarding on a passenger flight."
Pros: "Plan was hold, crew was not helpful. I requested a wheel chair and never got it. Flight was delayed and no assistance was given to figure out missed connections."
Cons: "Fix the above. Will not fly Turkish airlines again!"
Pros: "Nothing."
Cons: "This was the worst airline I have flown with. I booked my tickets last minute, it was for me and my 4 month old son. I had 3 suitcases a stroller and 2 carryons. I had paid for the suitcases, but because I was traveling alone I went there with my husband and he politely asked if they could please take the carryons on the plane because she can’t carry everything by herself. The manager came out and said that we have to pay. I said I already paid extra for my suitcases please help us because my wife is carrying our son, the diaper bag and 2 carryons. He was rude stating that we have to pay each carryon. We didn’t have the extra money and my wife took everything with her. If that’s how Turkish Airline treats their customers, they shouldn’t be operating. It was the last time I use this airline. No dignity or humanity, it’s all only about the money. And when I took the stroller with my son. They made me package the stroller by myself looking that I had my son on me crying and when I asked for help they said that they can’t help me... unbelievable... they see me with 2 carryons a stroller and a baby and they can’t help me."
Pros: "Food on the second leg ( Istanbul to Delhi ) of the journey was good."
Cons: "Poor Boarding In Chicago, no lines were formed to let people board in an organized fashion. Insufficien/inappropriate food ( BEEF Prevented choices ) - Eliminate beef from your food choices. Many people like me can eat Non vegetarian meals like chicken, fish , EXCEPT BEEF Ran out of the Salmon fish dish. I was given a snacking cheese sandwich instead! This would not have happened if you had selected other than a beef dish! Cramped seating. The airlines greed shows in picking out the seat placement design. The plane had extremely limited knee room. I'm five foot five inches tall and my knees were almost touching the seat in front."
Pros: "Food was tolerable. Good cabin temperature. Good lumbar support and pillow."
Cons: "Horrible leg space on the first leg of the journey. Air hostess we'e very inattentive. Asked for a blanket 3 times and still didn't get it. Also they had a poor attitude. Power outlets don't work on multiple seats. Oh and again no leg room. Zilch."
Pros: "The service was excellent, staff helpful and understanding."
Cons: "No business class priority boarding, no assistance available with transfer."
Pros: "Once my wife reached the gate, having left me behind at security, Turkish Airlines waited and were patient with us, the last to board the plane. The food and plane and bathrooms were all without any problems."
Cons: "We had a 80 minute layover in Frankfurt. Turkish Airlines should make note that this is not sufficient for making a connection. 1. The terminals require extensive walking. Not a problem except for time. 2. Security entering the terminal was seriously understaffed. There were a hundred security personnel, but thousands of passengers. The line stretched for half a mile. 3. Cutting, disorganization, mismanagement, lack of organization, and airport layout all contributed to making this a very stressful hour for us."
Cons: "Boarding was delaeyd 5 hour's ,Very very bag experience, the trailer baby and car seat i waited more than an hour, together with more people, were not found"
Pros: "The service was very nice and courteous"
Cons: "The seats don’t match up to the comfort level and privacy of the other airlines"
Cons: "The AC wasn’t turned on for 2 hours of passengers being on the plane and it was easily 100 degrees inside. Everyone was hot and miserable. The seats were also extremely close together. I have never been so uncomfortable on a long haul flight."
Pros: "Easy check in"
Cons: "Please include sea food in your menu"
Pros: "Nothing isn’t good flight"
Cons: "I don’t have any thing to say everything are bad even Airport too bad to find WI Fi also has unclean bathrooms over there"
Pros: "Nothing"
Cons: "Nothing"
Cons: "Lost my baggage, refused to give another ticket when getting to Istanbul late made me miss my next flight. Had to sit 10 hours and buy another ticket from another airline to make My destination a day late."
Pros: "Turkish airlines has great service and crew in plane."
Cons: "Hi, The flight was great. However my layover at airport lounge was long. I didn't like their (Turkish Business lounge)policy for not letting me have the room to sleep as the layover was more than 7hrs. I was told to ask for a hotel at reception. When i did, they said that they dont have any hotel inside and cant take me to ourside hotel too. The staff at reception of lounge was not courteous either. I only needed the room to sleep for 3 or 4 hrs. Anyway, the flight itself was great, no complaints"
Pros: "The service, food, convenience of a direct flight to Istanbul"
Cons: "The entertainment system in my seat did not work (they offered to change my seat but I declined). Also the WiFi was spotty. However, I always enjoy flying with Turkish Airlines due to the excellent service and delicious food."
Pros: "I sat in coach but was treated like I was in first class. Hot towels. Entrees were very excellent. The food was above what I expected coach meals to be from my experiences flying different carriers to over 8 different countries. The customer service was amazing! The lady flight attendant for my section was very attentive and friendly. When I came out of the bathroom, I accidentally interrupted one male flight attendant from doing his job, he politely gestured which reassured me that he would be right with me when he was done with what he was doing. I asked him if they had any heartburn or antiacids available which they didn't. These 2 interactions with the flight attendants made the flight very enjoyable."
Cons: "I was in couch and in the middle seat. I usually get the aisle or window so it was a hard adjustment to sleep in the middle seat because I didn't have leg room and couldn't lean my body against anything so I had to shift often to avoid my bottom from feeling numb."
Pros: "Comfort"
Cons: "They lost one of our bags."
Pros: "The service was impeccable!"
Cons: "Nothing"
Pros: "Crew service was amazing. 2 meals on the long trip, 1 meal on the short flight. Very satisfied"
Pros: "Boarding was smooth"
Cons: "Food needs improvement and staff should be more friendly."
Pros: "Flight attendants are professional and efficient, and the aircraft is clean and has an excellent entertainment center for all passengers."
Cons: "Rows are too close, with my knees pressed against the seat in front of me. That is misery for the 10-hour flight from Chicago to Istanbul. We had a much better experience when we flew Turkish Airlines a few years ago. Sad!"
Cons: "Crew was slow to pick up trays."
Pros: "food was excellent"
Cons: "Istanbul Airport could not tell me the gate of my connecting flight in a timely manner."
Pros: "There was a lot to choose entertainment wise."
Cons: "We had a child behind us who would not stop screaming and playing with the tray table. One of the crew members gave me a hard time for having my purse out for 1 minute while I was taking my prenatal vitamin even though we were sitting on the runway for over an hour at this point and the man in front of me had his chair fully reclined so I wasn't able to get to it under my seat.. Even though as she said, we were about to take off, but she didn't say anything to the man in front of me. This was my second time flying with them and the first experience was much better."
Pros: "That was good every thing, thank you."
Cons: "Nathing wrong."
Pros: "Food was good, airplane was newer than expected (nearly brand new, from the look) and the movie selection was excellent - and it was all free."
Cons: "More legroom would be nice. Boarding was a bit delayed for no visible reason."
Pros: "* Two suitcases * Vegetarian-Indian food was amazing! * You get a little pack with socks, slippers, tooth brush, eye cover. It is great!"
Cons: "Not enough leg room. When pushing the chair back, the cushion moves forward. Not the best for 6 feet and up people"
Pros: "Turkish Delight, food, seating that had leg room for my husbands long legs (we arranged our seats well in advance of the flight) ."
Cons: "Was hot before taking off then had cold air blowing directly on my neck. For most of the trip it was comfortable."
Pros: "Turkish Airlines is the best airlines we have every flown on in our international travels. The food is excellent. The service is excellent."
Pros: "First of all, the food is fantastic is you are not a meat and potatos (or big mac) kind of person. My original flight left late due to a hold up in security in Chicago. Turkish Air was very responsive and easy to work with when I missed my connector in Istanbul. Friendly crew. Clean jet. Will definitely use them agian."
Cons: "Nothing"
Pros: "I have traveled a lot during my life. The flight crew on this flight was the best I have ever seen."
Pros: "The food, the crew, the beverages, the entertainment and the level of cleanliness were all excellent. On time departure on both segments."
Cons: "The Boeing 777 had the new, smaller seats. No control of overhead airflow among other things. Wish they still had the old Airbus A330's and 340''s."
Pros: "Nothing whatsoever."
Cons: "Worst customer expireince ever. I was making a short trip to visit my very sick mother. Turkish Airline changed my connection time without notifying me such that I had 5 min left for my cooection in stambul. They gave me no other option and blamed this on Kayak and kayak blamed it on the Airline leaving me with no options. I had to stay in Birlin at my own expense. Complaint filed with Turkish airline resulted in nothing. I made several calls for update and only repose I got was we will send an email to the complaint dept. and you will here in 24 hours. This has been going on for over 5 days with no contect, update or resolution. Once back in the US, I plane to file a formal complaint with FAA and more. DO NOT take this airline. They are worst airline I have ever used and will never use it again."
Pros: "I liked everything, from check in to the end of my trip!"
Cons: "Nothing to dislike!"
Pros: "excellent services provided by the crew members, nice food, great entertainment (up to date),"
Pros: "I was very pleased with the overall service and comfort on my flight. Boarding went smoothly, and crew were friendly and helpful. Cabin service included Turkish delight, hot towel, an amenities bag, hot dinner, hot breakfast, and snacks available thought the flight in the galley. Entertainment was on demand and included a wide selection. Seats were comfortable with reasonable distance between rows for coach (better than on many U.S. carriers). They have ample restrooms and they are split throughout the coach cabin, which made lines for the restroom almost nonexistent. Restroom amenities include hand lotion and refreshing spray - very nice."
Cons: "Coach seats provide minimal leg room, and even less when seats are reclined."
Pros: "Leg room was great"

Great crew and great food. No self service/own device entertainment and that’s not acceptable these days

The best

When I arrived at the airport I checked my bags in and they gave me piece of paper and told me to wait and someone will come get me with the wheelchair. I am 84 and this was set up when I purchased my ticket. My flight was at 4 . I have waited an hour for someone to show up after 3pm . After that I was told I won’t be able to board the plane because it’s too late. What a mess! My bags were taken! I ended up taking a another flight few hours later . When I arrived at my destination I found out my bags are missing. Again! I am 84 all my bags were checked in . I am not able to carry heavy items . I don’t have my belongings, my medication! This is was horrible , horrible service . Not only flying somewhere it’s stressful as it is these days and then this! My flight was over 10 h plus all the time I spent at the airport that was freezing cold ! Again I am 84! This was a nightmare. Thank you Lufthansa for making my trip hard to forget.

Pros: "Very good food. Crew is nice and helpful"
Cons: "Business seats and in general the plane is just too old and not high standard. No screens even in business class"
Cons: "I got overcharged for a bag $230 Dollars, both planes were delayed, the supervisor Danny at Ohare was horrible, will never use Lufthansa ever again!"
Cons: "Entertainment unit was very slow and not even possible to operate properly. I had to ask for resetting it several times."
Pros: "Entertainment"
Cons: "Boarding process and food"
Pros: "everything from the boarding and check-in process to in flight comfort."
Pros: "Very helpful and accommodating"
Pros: "Crew is phenomenal! Food was good. Comfortable overall"
Pros: "Crew were amazing not stingy with the drinks. Boarding was easy and smooth"
Cons: "Would prefer flying with partner United though. Think they offered a better service on board"
Pros: "My luggage never arrived in Munich"
Pros: "On time, clean plane, good service."
Cons: "Lack of seating at departure gate, costumer agent at gate was rude about standing early for boarding (see first comment). Food was not my style my wife enjoyed it."
Cons: "The plane was kept at a ridiculous hot temperature the whole flight. There were no air vents above your head and it was god awful uncomfortable for 9 hrs. On our return flight they lost all of our luggage from our whole group of people traveling together. 8 bags lost in total."
Pros: "The service and crew was amazing! We splurged on Business class and it was worth it! I was impressed with their efficiency at every point: checking in, boarding, and in-flight service."
Cons: "Sleeping overnight the cabin got a bit warm which made it a bit uncomfortable. I’ve never had that problem on a flight before."
Cons: "There was a very unruly child on the flight. The attendants did their best to deal with him but it was quite chaotic for a long flught"
Cons: "I waa not allowed to bring my carryon bag and was told either I pay 100.00 or leave it there. Totally unprofessional and sounded like a scam."
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: "My daughters tv didn’t worked it was 8 hours flight, food- beef had not eatable pieces of meat with vains only- we had choice of beef and pasta only no chicken."
Pros: "Nothing"
Cons: "The plane was expected to land at FRa an hour early Andy they couldn’t wait five minutes for us after a three hour delayed flight. Every other flight was delayed on average 30minutes. When we arrived whoever was running the jet bridge took 15 minutes to get it out to our jet, essentially causing us to miss our flight right then. And then the staff had the audacity to tell us we had to hike back ten minutes to wait in an hour long line to rebook. When they could have done it at their gate just as easily. Simply awful service For paying first/business class"
Pros: "The entertainment was wonderful the staff was nice."
Cons: "CONSTANT ANXIETY!! Our flight to Chicago was delayed. By 2 hours. This normally is not a big deal but it caused us to miss our connecting flight from Munich to Bremen. Then our new flight with a later time to Bremen was cancelled 20 minutes prior to boarding with no more flights to this area. The service center helped us redirect another flight to Hamburg, Germany. We had to fly to Vienna and then to Hamburg. We made it to Vienna after a 40 minute delay however, this delay caused us to miss our connecting flight once again. We were placed on an early flight the next morning to Hamburg which was an easy flight. When we got to luggage in Hamburg we noticed our luggage was missing. Supposably still in Munich. We then missed this flight and missed out on valuable time with friends who live in Germany."
Pros: "The seats were spacious. I loved the options for viewing, klistening, etc on the tablets attached to the seat in front of me. Great service from the flight attendants. Lots of food service & drinks. Thankful for sitting close to first class."
Cons: "I would have preferred an aisle seat. Difficult to get out of the rows without everyone having to get up."
Pros: "Clean aircraft, quite and smooth flight, lots of entertainment options."
Cons: "I was never made aware of what food and drink options there were. I was asleep for the main meal and it would've been nice if they left a snack for me when I woke up."
Pros: "Service"
Cons: "Tight space"
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: "Service, etc was great"
Cons: "There was so little leg room on the transatlantic fight that I could not even cross my legs in front of me. And I am a petite woman. My poor husband (thin and tall) could barely fit in his seat"
Pros: "Friendly crew. Flight left on time"
Pros: "Service was great, meal was fantastic, seats were very comfortable, and the assortment of things they provided for entertainment were fantastic."
Pros: "I liked the entertainment options, beverage service, and leg room."
Cons: "I paid to reserve an upgraded seat. I specifically asked for a window seat and even have a confirmation email saying that I got a window seat (27 A). However, when I checked in, I was assigned a middle seat and the representatives at the ticket counter tried to tell me that was my preference. They tilde me to take it up with customer relations. If I pay $100 for a particular seat, I should get that seat!"
Pros: "Boarding efficient. Chicago counter very friendly and helpful"
Cons: "Some flight attendants friendly and helpful, others not so much Don't change your mind about an item or next time attendant will ignore you. If the customer speaks English, do not assume they don't understand German - so please treat your passengers well. Food was not good, have had better on Lufthansa"
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: "The attention to service. We traveled with an infant and Lufthansa staff was more helpful and attentive than any other airline we've filed with our infant in the past."
Cons: "Nothing"
Cons: "Will newer agan fly business with Lufthansa!! It's not business at all just regular econom seats with short leg room and casual service. They should be sorry for that kind of business!!"
Pros: "Attentive crew. Smooth flight!"
Cons: "All good"
Pros: "All good"
Cons: "No bad"
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 flight wasn't full. I was given a window seat with an empty seat next to it. I was able to move around and relax. There were lots of movies to choose from. The food was decent for a flight."
Cons: "Delayed flight. Offered free direct tv to everyone but then came back on and said the "button" to select free tv wasn't working so never mind"
Cons: "Missed connection along with about 25 others due to the delay getting to Lisbon (no reasons given)."
Pros: "entertainment and food was good"
Cons: "My wifes luggage was lost, no followup at all from Lufthansa (main) or in Seville which was our destination. We had to call to find out any information. Once the bag was found and delivered to Seville, Lufthansa personnel again did not tell us nor would they deliver the bag to our hotel as the driver had already left. We then had to wait another day to have the bag delivered to Granada. Terrible customer service, the bag was missing for four days causing us to spend time shopping for clothes rather than experiencing the city."
Pros: "Entertainment selection was good"
Cons: "Seating comfort was *horrible*! Looks like they've made the seats more cramped, especially when the seats recline"
Pros: "Lufthansa is one of the best in the world at transatlantic flights. There was extra room in business so they relocated me to a spot where I could have a bit more extra space. The food was wonderful. The service was wonderful. The flight left on time and arrived early. The seat was comfy. Really nice flight."
Cons: "Um, have to think. They could find a better ice cream? They should have turned on the outlets earlier so I could recharge my phone?"
Pros: "Liked the flight from Frankfurt to Chicago better when it comes to food and drinks. It was spaced out better and we were offered more drinks. It was very nice to have a seat changed when checking in at the airport without any problems or telling me to ask once on board."
Cons: "Seats not comfortable."
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: "Good flight good staff. Captain explained the route which is nice."
Cons: "No negatives"
Pros: "Great service and relaxing flight"
Cons: "Nothing"
Cons: "Nobody gave us information about 3 months passport expiration rule. So as we we were at the counter we found out. Lufthansa service at airport could not find next flight out for next day or 2 days out. So my daughter and i spent additioanally 3800$ for booking another flight 5 days later"
Pros: "The choice of entertainment was wide ranged."
Cons: "It was a big plane, and I was sitting at the back. When they started to serve drinks and our meal, both times it took way over half an hour for them to get to us after they started to serve."
Pros: "I loved the food for the flight and the service, it's always a pleasure to travel with Lufthansa. Awesome entertaining opportunities."
Cons: "Nothing really"
Cons: "The touch screen did not work properly"
Pros: "I liked how generous they were with food and drinks"
Cons: "Free WiFi could have made the flight a lot better"
Pros: "The plane ✈️ itself the attendants . The entertainment on board. Really great"
Cons: "Nothing dissatisfying about the flight nor the airline staff . Very polite, very professional. It was a Great flight. For long trips this airline is one of the best."
Pros: "Impressive service... amazing crew, very friendly and professional"
Pros: "Excellent crew, good food & movie selection."
Cons: "I congratulate the KLM crew!"
Pros: "Just as I expected. And I made my last connection easily."
Cons: "Travelled business class and was ace experience"
Pros: "Great crew, comfortable seating with enough leg room."
Cons: "Provide dinner before getting to joburg, instead of a snack. Flight arrives late so dinner would be appreciated"
Cons: "Late departure. Rush to connect."
Pros: "Crew was very engaging and service was good."
Cons: "My seat was horrible. Right at the door, crammed, and no place to store my carry-on luggage."
Cons: "This return flight was much better than the flight going to Amsterdam. I believe the biggest factor was the type of aircraft. The old 747 just didn't meet expectations. The newer 777 on the way back was much more comfortable, with better amenities."
Pros: "Crew was fantastic."
Cons: "This was the most narrow airplane seat I’ve ever experienced. So uncomfortable."
Cons: "I called for a crew member 5 times and waited 25 minutes for anyone to help me with just some water. I had to get up and go to the very back of the plane to ask for some water. The plane was hot and no air to be found. This was all after we had to get back off the plane before takeoff. It was terrib"
Pros: "Good food, friendly service"
Cons: "More trash pickup; only one round of beverage service"
Pros: "Once aboard the plane, all went well and I experienced excellent service from the cabin attendants."
Cons: "The flight was delayed (again!) for some 40 minutes and I was worried that I would miss my connection flight in Atlanata. Fortunately the pilot made up for the delay (probably costing the airline thousands in fuel). It seems these days that every KLM flight I take is delayed. This stretch goes back to 2015! Yet KLM prides itself as being punctual. Not the KLM that I have been flying!"
Pros: "Entertainment options."
Cons: "Service was poor, seat did not recline, and the food was terrible."
Pros: "We got to Amsterdam on time"
Cons: "1. Paying for the seats we chose...that will never happen again...I'll fly another airline first. 2. The food was terrible. I have flown KLM for years, this was not what I expected. 3. The plane was very dirty"
Pros: "Smooth flight."
Cons: "Seat a little cramped."
Pros: "Flight crew very nice"
Cons: "Paid $70 for seat with more leg room and was the exit role to main entrance. No overhead space for carry on: broken food tray holder. People stepping on my feet. And gather in your space waiting for bathrooms. Window seat had no room for feet because of closed door"
Pros: "Crew was excellent -kind nice and very attentive"
Cons: "Entertainment went out mid flight. Had to be reset off 30 mins but cam back up"
Cons: "Nothing special"
Pros: "Excellent service. A meal , drink and a coffee included which we were not expecting."
Cons: "Services was pretty weird .. Perse or crew Leader was ok But the assistent Young one was Really bad.. aptitud and not friendly at all."
Pros: "Friendly crew."
Cons: "So many people on a 747!!"
Pros: "Arrived early!"
Cons: "Boarding seemed disorganized."
Pros: "The crew was fantastic! Our needs were constantly being met and just about the time you thought you might want a snack or a meal, the attendants were already heading down the aisle. Because of an allergic reaction, I asked for ice a number of times and the attendants were more than happy to meet my needs."
Cons: "The seats were very close together. The trip from New York to Amsterdam seemed a lot more comfortable than the return flight. The food from NYC JFK was better than the food from Amsterdam. The movie selection on both flights was a little disappointing."
Cons: "Our total flight time was about 17 hours - MAD- AMS-LAX. My husband and I both have an internationally approved carry on luggages with us. When we checked in - they asked us to both check in our carry on luggage. The reason why is because they said they don’t think they have enough space for our carry ons. I told the crew member checking us in that other people that was checking in with the same hand carry size luggage with us had no problems taking it with them. For being about to be on a 17 HOUR FLIGHT we should be ALLOWED to have our carry ons with us! We take carry ons for that reason! I had to argue and prove my case to the crew member to atleast keep 1 carry on with us. I thought that was an UNACCEPTABLE reason for us to check in a carry on luggage when we had a 17 hour travel time ahead of us. Not a happy costumer here."
Pros: "Very friendly crew going out of way to assist in making trip comfortable"
Cons: "Had travelled KLM to Amsterdam on my first flight 27 years ago and the aircrafts are stuck in that age! Lousy seats, poor quality bathrooms, lousy screens, prefer not to fly them"
Pros: "Nothing really"
Cons: "Flew KLM 27 years ago and the airlines seem to be stuck in the same era. Food is poor quality... Have you recently checked the Gulf carriers."
Pros: "Really friendly staff. Great service"
Pros: "I got some rest"
Cons: "unable to charge my phone or watch movies"
Pros: "Great service"
Pros: "Food was good and crew members were very nice"
Cons: "My check in luggage was in very bad condition when I receive it. My clothes were all wet and they got bab by each other’s colour. Many clothes are not in a condition to wear now. Those were expensive and I had a big loss because of that."
Pros: "Premium economy service was good."
Cons: "Inexplicably, our preassigned seats were changed at checkin and we were put in bulkhead. This particular Boeing aircraft is pretty poorly designed. Especially the bulkhead in premium economy."
Pros: "Booked extra room seat which gave me good room for seating"
Cons: "Please Endeavour to put the expiration date on the food served in the flight."
Cons: "The 767 is configured oddly and th business class seats are so narrow it feel like you are sleeping in a coffin"
Pros: "Very friendly service!"
Pros: "My bagage broke"
Cons: "I paid extra fee for extra bagage which was tv and i paid insurance my tv broke and no one responces for it"
Pros: "Everything. A truly faultless experience!"
Cons: "Nothing"
Pros: "Crew good flight was fine apart from delay due to fog in Amsterdam but kept informed"
Cons: "Flight was delayed due to weather in Amsterdam area"
Cons: "Without any explanation the plane I was due to go to Istanbul on at 11.30 was not available. I had to wait for a small plane coming from Edinburgh then wait for it to be emptied of passengers and cleaned. This meant we were over 2 hours late into Istanbul. No explanation or apology. I then missed my next flight in Istanbul and had to purchase another ticket. I cannot believe that air passengers are treated in this way!!! I will follow this up with KLM when I go home from my holiday."
Pros: "Thankful for coffee being served without charge. Not all airlines do that."
Pros: "Cabin crew very pleasant"
Cons: "Lost our bags, little sympathy from staff"
Pros: "Very little if any."
Cons: "Aircraft was not very clean,the staff seamed quite harsh at times when speaking to customers. The food was really quite poor but it was a short flight to be honest. Overall not as pleasant as the China Southern flights. I would not like to choose them again unless i had to."
Cons: "Not only was there free food but they tried to sell you a bunch of stuff. Not a moments piece."
Pros: "Atmosphere, crew were very professional and friendly"
Cons: "Seats were a little too narrow, and quite uncomfortable when a broad shouldered person is sitting next to you"
Pros: "Great smooth flight staff was pleasant and the overall experience was fantastic."
Pros: "It's the best flight I could get for such a low price. But don't expect to to get the best and newest planes around but it's still overall a good experience."
Cons: "Quite bummed that the flight didn't have wifi / USB):"
