Cons: "Amazing how little legroom you can get away with, on a 13+ hour flight. You should be so ashamed!!!"

Cons: "No one came with drink carts until halfway through the flight. I was very hungry, never offered food. Boarding was late but no communication from staff."

Pros: "Slept in the flight for 5 hours and my toddler did too , was quiet in the cabin and this is the only good thing"
Cons: "Boarding they kept me and couple othee guys like seeiously 5 staff people at the gate doing nothing and you ask anyone please help i want to tag my stroller so i can board ans go on boarding line, no response only one peeson will work. the rest of the four are completely useless, i eventually told my wife to board with our daughter so they have the time to sit and prepare food etc and pull things they will need durimg flight Andi waited on this last staff person at the gate until she gave me the tag to the stroller and boarded later First meal they said either fish or beaf meat balls, i like both and no problem, but the crew said no fish anymore so you you will take beaf, OK Luckily neither my wife or daughter ate it Because after I ate it, 3-4 hrs later, I had the worst stomach pain ever and was in pain the rest of the flight and the remaining of the day after we landed FYI I ate just crackers and like all bread sandwiches all morning and was completely fine- just the beaf meat balls either not cocked or remains of non good beaf and other things- horrible food"

Pros: "Nothing much what a terrible ariline"
Cons: "Turkish Ailines delayed by 5 hours. had a long layover fo 24 hours in Istanbul, forced to pay for my visa and was not even give a receipt by immigration. I think hey pocket the money"

Pros: "Quality service and efficient"

Pros: "good people /service, good food and comfortable seating nice experience all in all"

Pros: "Easy check in On time Good inflight tv Good food What more can one dream for except free upgrades ??"
Cons: "Passport control in Istanbul horribly chaotic and long."

Cons: "The airport in Turkey had no a/c it was sweltering and packed. It smelled to high hell. Boarding was crazy with people shoving and pushing and cutting each other to get throug"

Pros: "Good food, good crew, free beer"
Cons: "Late by 20 minutes. Touchscreen is starting to go out."

Pros: "Crew were polite and helpful"
Cons: "Seats were especially cramped and tight and leg room was uncomfortable and I am a short person."

Cons: "I didn’t like the nearly 3 hour delay that caused me to miss my connection, and how poorly that was handled. I just lost one day of my 10-day vacation"

Pros: "Screens at each seat"
Cons: "Food was terrible, the WiFi wouldn’t work even at $15"

Pros: "Excellent Staff very courteous and professional 5 star +"
Cons: "The Internet is complicated and not working all the time. Business class seats are dated need to be upgraded, comparing to other airlines."

Pros: "leaving and arrival on time."
Cons: "No leg space in economy."

Pros: "Nothing"
Cons: "The counter could not find my reservation a d they said because i booked online i had to go to another counter and then back to check in. It was pretty stressful"

Pros: "The international pods were wonderful. Lots of space and could choose from a ton of movies. the bathroom was oversized with plenty of space. And the Bentley travel packs are a very nice touch. The highlight of the trip though is the Turskish Lounge in Istanbul. It has several grand pianos, tons of iMac stations, a freaking golf simulator, and different food stations. Thai, Turkish cuisine a salad bar. It it the best lounge I have experienced 10 fold. It’s the size of a mall."
Cons: "One negative was the beverage service. Iberia and Korean air are much more attentive before and upon take off. Beverage carts come around quite often. Turkish, not so much. Also food was just okay. Feel like other airlines do better in business class"

Pros: "Service and team"

Pros: "The Lounge at Istanbul airport is fantastic"
Cons: "Seating in Economy class is terrible. For tall persons like me it is a punshment to be squeazed in such a narrow space. Turkish airlines should add more space and comfort with their seating in Economy. Introduce a Premium Economy Class would solve that problem"

Pros: "There was ample leg room in economy. The food was good. Plenty to eat. Good selection of entertainment. Boarding was relatively good."
Cons: "I did not like the fact that my U.S. bound plane had to be boarded from the tarmac. I’m assuming it had something to with u.s. security issues with carriers from predominantly Muslim countries. The crew need to check passengers that want to place their feet anywhere except the floor or footrest. I see exactly how fights happen in the planes. It is not ok to place ones feet on someone else’s armrest."

Pros: "Flight attendants were not helpful or friendly."
Cons: "Flight attendants were not helpful or friendly."

Cons: "Boarding problems"

Cons: "My family and I bought our tickets months in advance. We had selected the seats right next to one another. When we go to airport and check in we noticed they placed 2 of us on the same seat! So we ask them to correct it. They instead break us up into random locations on the flight. That's not even the worst of it. When we get in the aircraft our seats were taken up by other people. we had to wait for everything to pass us inside the tight rows to find other seats even further apart. We payed for seats together."

Pros: "In flight entertainment is great! Good selection of movies, nice screens."
Cons: "No vents at seats on Airbus 300, AC was set at high temp so I was frequently way to warm to be comfortable. This is on both our main flight to Istanbul and our short transfer to Athens. Drink service did not start until 2 1/2 hours into flight. You get what you pay for I suppose. Still 10.5 on a hot plane!!! I usually need a jacket. Food was ...awful."

Pros: "Food and entertainment. Comfort of seats"
Cons: "Crew not helpful, flight delayed, no help when I missed my connecting flight due to the delay"

Pros: "Entertainment is good, many movies and games for kids."
Cons: "Flight attendants are rude and food was terrible! No menu and no selection to choose."

Pros: "We arrived safely and on time"
Cons: "The seat spacing on that flight was some of the tightest I have ever seen - worse than even most of the short-haul (Embraer) flights i have been on - barely manageable for 3.5 hours. Flight attendants were borderline rude and bossy, but they had to be, because the passengers were loud and unruly."

Pros: "The seats were comfortable and the first meal was great! Staff was friendly and the bathroom was VERY clean and nice."
Cons: "I didn't like the multiple, repetitive announcements. I would suggest that once the guest has picked their language preference on the screen, they then only hear announcements once in their preferred language. Also, our first transfer flight with Turkish allowed for us to carry our personal camera, but then on our main connecting flight we were told that we couldn't have it as a carry on. We would have stowed it in checked baggage had we been previously told. This was incredibly frustrating."

Pros: "Turkish flights are consistently comfortable, service is good."
Cons: "I purchased a flight during the day, but ended up on a red-eye anyway."

Pros: "Short"

Pros: "The food was delicious."
Cons: "The wait times were ridiculous and always off schedule. From the beginning of the trio to the end of the trio there was consitency in going off schedule and being forced to stand in lines for hours. I would not fly Turkish again."

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!"

Pros: "Besides the birth of my daughter, this trip to Italy through Istanbul was the greatest THING that I've experienced, EVER! My flight with Turkish Airlines was a HUGE part of that odyssey!"
Cons: "Because of my delayed flight from Atlanta, I missed my connecting flight from Turkey to Rome! So, in the future (yes I plan on flying through Turkish Airlines exclusively for international travel), I will book my flightts with a larger "gap" between flights! Otherwise....Turkish Airlines is PERFECTO!"

Pros: "Great flight overall. Comfortable, nice amenities. Staff was polite and helpful."
Cons: "Did not like the carry on being based on weight instead of size. Also did not like that there was not a self check in kiosk."

Pros: "I was treated much like a first-class customer flying in coach. Food and beverage service as quite good. Turkish Airlines certainly beats any of the US airlines' on-board coach service by a long shot."
Cons: "I didn't like having to check my laptop at the gate. I wished they would have told me advance, as I was planing a lot of work on plane, and could not."

Pros: "Food was good."
Cons: "Seats where extremely uncomfortable. Flight attendants and aircraft staff were so rude and unfriendly at all."

Cons: "The food wasnt good"

Pros: "Chair did not recline properly - 16A/B"

Pros: "This is a government run airline with very poor customer service. I flew 6 flights in December, 2016 in business class - out of which 5 flights were late. There was no help at the transfer desk in Istanbul to get onto another flight as my connecting flight was missed because the original outbound flight was late. The customer service staff both at the lounge and the transfer desk were inept and rude and did not want to help. I shudder to think how economy passengers are treated."
Cons: "1) No organized boarding process - there is a general melee at the boarding gate with a lot of shoving and pushing. 2) Customer service staff are rude, incompetent and unhelpful 3) No recognition that customers are to be served 4) Food selection in business class was mediocre and poor 5) Old aircraft - on flight from Istanbul to London, business class was 3 abreast with the middle seat being used as a tray table. 6) Sleeper class is mediocre - seat width is poor and one cannot even turn on the side"

Pros: "The crew was nice They handled the delay well so we didn't missed our connection afterall"
Cons: "1. We had to wait 2 hours in the plane 2. there is no way to use the monitors (not a personal monitor)."

Pros: "Overall journey was ok"
Cons: "I am vegeterian. Food was horrible :("

Cons: "Refused to refund cancelled flight"

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: "Movies!"
Cons: "This is one of the worst airlines I have flown with. I travel internationally frequently, I had used Turkish Airlines on a domestic flight in Turkey back in the 90's. It was a decent experience. So I decided to book my flight to Athens with Turkish Airlines. I bought a nonstop flight from LAX to with one and a half hour layover in Istanbul and then flying to Athens on the same day. I was assigned bulkhead seats on the way over. On the day of the Parcher at the Turkish airline counter in LAX I was informed that my seat assignments were changed. The agent could not/ would not give me a satisfactory answer as to why! During the course of the same conversation I was also informed that my layover Istanbul is not 1 1/2 hours, instead it is seven hours and I will be flying out to Athens The following day. My flight was randomly changed to a later flight without my knowledge! After a long wait at the ticketing counter, the manager switched us back to the original itinerary. Sadly it doesn't end here. The take off was about an hour and a half delayed. This was about exactly the same amount of time I had as layover Istanbul airport. I asked several flight attendants about how will Turkish Airlines will handle this delay as my connection to Athens was in jeopardy. Again not one flight attendant could give me a straight answer. Some said "well hopefully you will make it to the next flight". One said "the pilot we will make up for the lost time". I also noticed that my original bulkhead seat assignments were given to three ladies who were friends of a first class flight attendant! it was really annoying to watch the flight attendant bring them treats from the first class kitchen area. It was clear that our seats were intentionally switched as a special favor. Long story short, upon arrival we were told that the our connecting flight is at gate 501 only to find out there was no plane at the gate!! We never found out what happened to our original connection to Athens, but we ended up waiting an additional 5 1/2 hours in the airport for then next day flight. No explanation given, no accommodations provided, no apologies!"

Pros: "Friendly crew."

Cons: "Checked bag got ruined, servie was terrible"

Pros: "Cabin was clean. Food and drink was OK"
Cons: "No AC while passengers on board waiting for take off. It lasted about half an hour. people were forced to use airline magazines as fans. No TV news or sport to watch Toilet was not clean. My seat can recline easily without pushing the recline bottom. This was a connection flight. Passengers had to go through 4 check points. Too much redundant. At the last check point, 4 gates shared the same check point. We saw a line but no sign for it. So we went to the front to find out what the line was for and went back to join the line for security check. There were people who did the same thing but tried to cut in the line right at the check point, creating chaos."

Pros: "Crew is great, Food is good. Overall experience is excellent. Recommend 100% ."

Cons: "40 min delay of the first flight got me into a waiting loop of 5 hours at Istanbul. Boarding included waiting time in the cold bus for passengers who arrived delayed. Security check was extremely slow - one xray machine for all passengers arriving from Dar. All in all had already better flights with Turkish"

Cons: "I didn't even go"
