Pros: "For the first time, my vegetarian food was pretty good and I didn't have an upset stomach as soon as I landed in India. It was a miracle for me. Thanks, Qatar airways."

Cons: "Catering and seating. They ran out of food and drinks"
Pros: "The seating, crew members, and entertainment was really good."
Cons: "I was given two options to choose from for brunch which were scrambled egg with sausage and paratha. Upon asking for paratha I was told that they ran out of Paratha. This happened very first time with me. Even though the crew provided me with excellent service I was surprised to hear the Qatar Airways could run out of food?"
Pros: "-Great selection of movies, Ted talks, and games to view on individual screens, headphones were provided. - Blankets and pillows were provided to everyone, along with a kit with toothbrush, toothpaste, socks, and eye mask. - Adjustable head rest."
Cons: "- Tiny, cramped seats and aisles. I'd heard the Quatar has more leg room than other airlines. This is definitely not true. If the person in front of me reclined all the way, they crushed my knees and I'm only 5'7". - Bathrooms were dirty by 4 hours into the 14 hour flight. Sinks clogged, garbage can overflowing. Not just one bathroom. Gross. - Worst flight attendant service I've ever had, and I don't expect much since I've traveled a lot. Service was rushed, coffee cart for our side of plane never arrived, when I walked to the back to ask for some, they couldn't find the milk and made a fuss about looking for sugar. Lots of similar examples throughout the flight. - The baggage claim carousel number never appeared on the screens at IAD after landing. Other flights showed but not Quatar. We waited a while then walked around to check them all until we found the right carousel. Never seen this happen before. - One of our bags never appeared, so we waited until all luggage had come out and checked with the counter. They found our bag somewhere and brought it over after a 20 minute wait. No explanation given. Good thing we'd counted bags."
Pros: "Very nice"
Cons: "Crews walking between the lines. They don't care pushing to others. They never said sorry for that."
Pros: "The best service"
Cons: "Nothing bad to say"
Pros: "Excellent service and aircraft! Top tier entertainment and food and wine."
Pros: "Very comfortable seats with lots of space and pillows blankets and other ammenities. It was a 13 hour flight and the staff came by many timea with drinks and snacks"
Cons: "I have flown previously with Qatar and was not so impressed. Everything was great this trip up until my return to the United States. I should have suspected a problem when I was requested to change seat in order to assist a family who were in separate seats. Moving was difficult as the plane was being loaded. I managed to get to the seat offered to find someone sitting in it. To top it off the individual was wearing a surgical mask and carrying a large immigration bag. I requested a seat forward but I was denied and I later saw other passengers moved forward to seats that I was denied. If I had known that the flight would have been full of possibility sick immigrants I would have chosen another flight or airline. At certain times the smells were very bad. I felt as a ff member I should have been treated better or been made aware of possible health risks."
Cons: "No leg room, very confining. Food so-so. I do not recommend traveling on this airline."
Pros: "Seats are very much smaller in economy. Hotel accommodation was no where close to good in comparison to Emirates or Thai."
Cons: "ANAZING flight staff! Friendly and courteous!!!! Loved them on all four flights!!!!"
Pros: "The crew was excellent."
Cons: "The flight was late boarding everyone on time. It was delayed 1.5 hrs. The entertainment system had its fault, as it was difficult to navigate between screens. The seats were uncomfortable and not enough room for such a long flight. The kids were extremely uncomfortable on this flight, as many were crying throughout the journey."
Cons: "I never made it to the Yerevan to Doha flight, because Qatar Airways did not get me to my destination in time. They had an emergency landing in The Azores, after turbulence and several passengers got injured, when the pilot failed to warn passengers to put on their seat belts and they flew into the air, hitting the ceiling before falling down. One passenger had a heart attack. Once they de-planed us in The Azores, not a single Qatar Airways employee helped us on site anymore. Passengers were left in the hands of hotel and airport staff. There was very little communication with the passengers. A relief flight was supposed to come in 12 hours. It did not come for another 35. After the emergency landing, some passengers noticed that a wing looked defective. The disruption may not have been due only to bad weather, but a defective plane as well."
Pros: "1. Comfortable. 2. Good crew 3. On time 4. No hiccups."
Cons: "1. Not having wi-fi (major) 2. No news channels in in-flight entertainment 3. No snacks"
Pros: "Qatar Airlines was amazing food was great and the flight attendants catered to passenger needs."
Pros: "Liked the entertainment options with a large movie catalog."
Cons: "Customer service by phone, boarding process, width of seats, speed of cabin service."
Pros: "The crew and the airline was a great experience."
Cons: "I wish there was more leg space between the seats."
Pros: "I have been in qatar airways many a times and they have done an excellent job connecting Kathmandu to outside world. The experience is usually very nice-the plane is in good condition, the fly crew are always smiling and helping, the food and entertainment are great."
Cons: "May be this is one time thing, but the ground crew were terrible, particularly the man who was on the check-in counter. Spoke with a robotic tone and was very rude. Spoke as if he owned the plane and we were asking for a free ride. Very disappointing start to a long journey."
Cons: "The luggage management system was terrible. We had to wait 2 extra hours for a single carry-on that we had to check in before our 15 hour flight. After a 24 hour journey, it is really inconsiderate to add extra hours to the journey. For luggage, I would give a 1, very poor rating for Qatar Air."
Pros: "Great flights. Lots of room in economy, which is needed for a 14 hour flight. Also excellent personal entertainment system in the seat. This was my first flight on Qatar airlines. I will definitely book on Qatar again."
Pros: "Entertainment and food"
Cons: "Could not sleep... Need more room"
Pros: "Crew was phenomenal. Felt safe and cared fir on flight."
Cons: "Food choices seemed a little under the Qatar standard considering the high level of quality for other aspects of this airline. Not airlines fault but took too long to get yo terminal at IAD Leg room a little tight in economy of 777"
Pros: "For a change, I found the cabin crew extremely courteous and helpful. A remarkable change from the last so many flights flown across different airlines."
Cons: "The entertainment system is poor. Hardly any movies/shows worth watching. The leg space sucks. Agree I was flying cattle class, but even then it seemed to be too cramped."
Pros: "Better than costumer service in Thailand"
Pros: "Crew was very helpful."
Cons: "Food was terrible."
Pros: "I liked very much Qatar airways. Hope to fly again."
Pros: "What I really impressed me over other airlines was the choice of movies and other entertainment"
Cons: "What I really didn't like was the food. ex. I asked for Hindu good. The choice of chicken I had was never ever cooked by Hindus. The chicken was looking something like a small hot dog served with potatoes which is never a part of Hindu meal. Also the curry was less making the passengers eat dry rice. Some passengers had pickle as choice some had some kind of butter to eat with rice and curry which could never be a combination."
Pros: "Crew was very helpful"
Cons: "Cabin was very hot"
Cons: "I didn't get any food for my baby"
Cons: "The food choices were not very good. However there was a good selection on the beverages and they were complementary which is also good"
Pros: "Some crew was attentive, others were not. Piloting was good"
Cons: "Upgraded seats in the planes, especially business class, seats did not work properly or recline all the way, very uncomfortable. Food was mediocre at best, movie library needs updating. I'm also not sure why an older model of this aircraft is used on such a long haul flight."
Cons: "Our flight from Kathmandu was delayed so we missed our connecting flight to Vienna. We don't know why it took so long to organize the hotel. Turkish Airlines was ready with new boarding passes but we waited two hours at the hotel desk to get a bus to the hotel where we again had to wait till they gave each passenger a room. If they organized the boarding passes ahead of time, why not the hotel? So we were quite exhausted. The plane was again delayed leaving Istanbul. Movies on flight not what they used to be."
Pros: "Food and service were great."
Cons: "The usb charger was broken"
Pros: "The crew, food, and choice of entertainment."
Cons: "Customer service in Istanbul was tribble . No help at all with any kinds of questions and issues. The airport staff were unbelievably rude and non responsive, as if they were there to turn off the passengers. Will never travel with any airlines that has to stop in Turkey"
Pros: "Friendly airlines and service was excellent."
Cons: "No anything"
Cons: "The food wasnt good"
Pros: "The Knowledge that I would never fly Turkish airline again"
Cons: "Cancelled flights without contacting me Delayed takeoff for 9 hours. Took off knowing they would not be able to land in Istanbul and dropped us off in Izmir Did not cover the cost of food at the hotel in Izmir. Took us to a hotel over an hour away from the airport"
Pros: "We had a great flight other than the uncomfortable seats. The food was outstanding and the staff the staff was very accommodating. I was glad I was able to charge phone/tablet on the plane"
Cons: "My seat didn't lay back, which made it was difficult to sleep. The seats are too close and generally uncomfortable. I just wish we could have toured Istanbul since we had a long lay-over. Took forever to find out where the tour was only to find out we needed Visas. The airport staff was not helpful. The bus tour is promoted on their website, and it sounded like it was easily accessed as soon as we were off our flight from Johannesburg. Not so."
Pros: "Love the entertainment choices, behind able to watch while seasons of TV shows, new movies. Makes the time pass easily."
Cons: "When you are doing a long flight, you don't want fruit to be the only choice for dessert. It's hard enough being gluten free but to find that nearly every airline just thinks that fruit is acceptable is disappointing. They did provide a gluten free bread roll rather than the usual rice cakes but on two recent legs, didn't heat it. When I told the flight crew the second time that it is inedible when not heated, he was great and said he would do that. And it is nice to eat grilled vegetables which are delicious but sometimes particularly on a long flight, a bit more variety is needed. Turkish Airlines is excellent but fixing this would make it great."
Pros: "Everything was great. Would never fly another airline if Turkish was available."
Cons: "You must hear this all the time. An eleven hour flight is torture. Maybe a little more padding in the seat cushions. Still, You Are GREAT"
Cons: "Worst boarding as flight was late and who ever was boarding us was rude, I get in my seat was taken, flight attendants were the rudest Iv ever dealt with, anything I asked for was not available, air conditioning was not working in the middle part of the plane. I could not stand sitting so I stood in the back the WHOLE 10 hour flight from the heat. I was so uncomfortable I will definitely take action on this one. I will demand a full refund the whole way I was extremely upset."
Pros: "I had not had the possibility through the third party website to precise I woud like a vegetarian dish, but the staff could arrange it on the plane. The food was delicious."
Cons: "The contrast of the screen was bad, it was hard to see if the scene on the screen was a bit dark."
Pros: "It was an excellent trip with THY. The crew was very attentive for the requests and the needs of the passengers at all time (regardless of inconsiderate traveler). Since it is usually too expensive for me to travel with THY, one still can get a great deal if looked for deals in advance. Some of the best things about traveling with THY are being able to check 2 bags, unlimited drinks and food at all times and more leg room. Max"
Pros: "For a long flight, most were able to sleep. The crew was very busy during the first couple hours and also very present. Movie choices were wonderful. I was lucky enough to have an empty seat next to me although when the man in front of me reclined, his head was practically in my lap."
Cons: "After first service, the crew disappeared. I get very thirsty and was in need of water more often than they were willing to pass it out. I did not go to galley to request additional water, which likely would have been provided! Passengers made a MESS in aisles & lavs, which was not picked up thru the flight."
Pros: "The flight was very pleasant. I was traveling wit my 2-year old and they brought him a little Batman vs Superman bag with an inflatable airplane, airplane binoculars, and slap on watch. They also brought him an activity book. I thought this was a lovely touch that helped keep my child entertained on our long flight. Adults also received a goody bag with grippy socks, slippers, eye mask, lip balm, toothbrush with toothpaste, and ear plugs. It was a pleasant surprise."
Cons: "Someone was escorted off our plane when our flight landed for unknown reasons. This was the day after the terrorist attacks in Belgium at the airport and metro, and the crew asked the person being escorted off the plane if he had taken all of his bags. If this person was a terrorist, do you really think he would just tell you if he left a bag of explosives on board?"
Pros: "The dinner was good but they ran out of chicken immediately so there was only beef. Meal service is very slow and it takes them on average an hour to take the trays away. The lemonade is very good"
Cons: "No leg room. Very uncomfortable"
Pros: "All of the above , on this flight. it was just as expected and better. Thank you. Thought you might want to know my opinion of our flight from Washington to Istanbul on Jan.27.2016, it was the worst flight on any airline we had before. The crew was unprofessional at best, no one knew his or hers duty. the most was the cook who took the orders for food and 2 hours later came to apologize that he did not have the food or that the food was ruined. It was like a joke all along the flight. I hope the at crew do not work for your company anymore."
Pros: "No problems"
Cons: "Excellent service"
Pros: "The flight was long and the comfort somewhat limited. I was expecting that and I was not disappointed. However, when we reached IAD, the customs check was very quick and the luggage was already there. A very good ending to an arduous trip. Entertainment was first rate and the food prepared with some degree of skill."
Cons: "flight crew did not make much of an effort to secure my purchases from the duty free store. The items never made it and refund had to be issued. Not their fault, but no real effort to contact the store and have the items brought to me...... my fault really,,,, otherwise I would recommend this airline to anyone flying overseas."
Cons: "Waiting time was too long between 2 flights"
Pros: "Good flight."
Cons: "Food was not good."
Pros: "I Am like The Service"
Cons: "I Am like everithiry the service and food"
Pros: "Usb charging, entertainment was nice."
Cons: "Ran out of chicken dishes- only had beef to offer. Seats were slightly uncomfortable. Crew was not very friendly/smiley."
Pros: "Loved the food service."
Cons: "The cabin was very hot? How do they work like that? I'm surprised the flight attendants didn't get heat stroke. Anyway, I suppose its cultural as I noticed a lot of places overly heated in turkey."
Pros: "Food and drink made two long trips very comfortable."
Cons: "My trip originated at Ivato airport in Antananarivo, where even with only one checked bag weighing 12 kg, and the proper carry on, I was harassed for bribes. An hour after clearing security, I was called down to the baggage area, where after emptying my 12 kg bag, "national police" lost my transit tag for final destination in US. Turkish Air employees made the extra effort to print out a new one, but I was asked for "gifts" or "rhum" by 3 different Ivato police, baggage boys, etc."
Pros: "Staff was welcoming, accommodating and very courteous. The seats were comfortable and they had a great selection of movies to keep me occupied on 2 overnight 8 and 10 hour flights. Food was good too!"
Pros: "food good, lots of selections. liked the movies/tv shows. seats were fine, not too much wiggle room but okay crew was great. very attentive and helpful. no attitude like you get on domestic type US flights"
Cons: "too much lemon smell in bathroom."
Pros: "Good service on board."
Pros: "Nothing at all"
Cons: "Not comfortable"
Pros: "I liked getting to my destination finally, and the timely meals."
Cons: "The crew was unfriendly and not helpful when I asked for assistance signing up for a rewards program card. I requested the opportunity to take a picture of the Himalayas as we flew over out the window of business class which was unoccupied and i was told that was not permitted. I got laid over for 55 hours in the Istanbul airport lounge and the staff there was unfriendly as well, and no one spoke English...at all. It was disheartening, and very frustrating."
Cons: "food and entertainment package was not at all good. co-passenger drinks heavily and makes me uncomfortable as she was totally unbalance"
Cons: "no leg room entertainment was lacking..."
Pros: "When they did speak clear English they shouted at passengers to 'Shut Up and you'll wait'."
Cons: "Counter people at Turkish airlines in Istanbul told us to 'Shut Up and you'll wait'."
Pros: "The flight crew was great. Food was excellent and very little turbulence on this flight."
Cons: "We missed the flight due to Turkish airline airport staff being incompetent. Flight was delayed to 4 pm from 12:35 the day before and we did not leave until closer to 6 or 7 pm. I would not recommend flying into Istanbul as the airport seems to be very disorganized, and might not totally be the fault of the airline. We waited for 3 hours to get new boarding passes for a new flight and then after waiting 3 more hours in the hotel line, Turkish airlines said "we are out of hotels" and left a large number of customers stranded at the airport. When trying to get reimbursed for the hotel, the staff at the airport was clueless. I won't be flying Turkish Airlines again."
Cons: "By far Turkish Airlines has the least amount of leg room available on an international flight (coach class) that I've ever traveled . . . and I'm saying that as a career pilot. If you are over 6' tall, you will be in agony on any flight that crosses the pond (I traveled on their Airbus A330 and Boeing 737 . . . same story). My tailbone was pegged to the back of my seat, yet my knees were still smooshed into the seat in front of me. I was absolutely miserable. I ended up standing in the back next to the toilets for over 2.5 hours of the 10 hour flight because that was more comfortable than sitting in this cattle car."
Pros: "I enjoyed the meals and the service,"
Cons: "The zipper in my new suitcase was broken at the IAD airport."
Pros: "Great hot meals and in-flight entertainment Comfortable seats"
Pros: "Best of the best so far!"
Pros: "I didn't like there service b/c they weren't helpful at all. Also I had my baby with me and they didn't give her anything to play with as usually airlines do."
Pros: "Wifi on some flights"
Pros: "from the people in the airport to the air crew, they provide a great service! further than any other airline. I have fly twice with them and is always a pleasure."
Cons: "Selection of movies can be better!"
Pros: "Friendly staff. Delicious Turkish Delights and hot towels served after takeoff. The best features though were how they handle long layovers in Istanbul. If it's during the day there's a free tour of the city and overnight we were given a fantastic hotel with shuttle and wakeup calls. That made the long flight much easier."
Pros: "Fast boarding"
Cons: "No wifi on the plane"
Pros: "Amazing service Great Food Best attutude in the sky (flight attendants)"
Cons: "The heat before take off"
Pros: "Service and other legs more uptight crew set bad tone while getting a stretch near bath rooms -12 hour flight!"
Cons: "Crew was not so friendly"
Pros: "Seats were TOO close, my knees were jammed into a seat back for 11 hours and the people next to me were incorigable."
Pros: "Food was excellent, well presented. Nice crew. It's the little extra touches that make this airline nice. Bathrooms were large and well kept cleaned."
