Pros: "Good service/Crew food quality and choice good."
Cons: "Need more choice of British TV Programmes rather than American"
Pros: "Good crew, fair choice of food and drinks and served whenever you want it. Good array of entertainment on offer but our flight was a 'sleeper' so after a fumble with the controls and the limited new releases, I opted to read instead. Not sure we like the Dreamliner configuration and levels of comfort more than the 777 or Airbus offerings but it was fine."
Cons: "A couple on our flight decided it was OK to have their 4-year old run around the cabin shrieking and causing a lot of fuss. Most of us in the cabin complained but these parents were pathetically weak and elected to allow it to continue. No sleep... spoiled experience.. miserable flight in this respect. Terrible Business Lounge 'Aspire' in Gatwick; dirty and poorly equipped - not even Prosecco on offer without paying £5 for a small glass. Qatar should stop using this dreadful place. Crew seemed to have stopped referring to the passengers by name and offer a less-personalised service in Business than we have become accustomed to. The food choices while good, have been paired back as have the selection of wines."

Next problem was their REFUSAL to give me an aisle seat. I reserved an aisle seat originally, aisle seats were available when I tried to change, but agent REFUSED to accommodate me with either aisle or window. Sat in middle with huge guy next to me.

Cons: "When dropping my bag at check in counter, the employee at the counter asked, somewhat intrusively, what the extra fee I paid was for. When I told her it was for the Al Mourjan lounge in Doha, her facial response and attitude came across as judgemental, and was not appropriate"
Pros: "The flight attendants were very friendly. On the flight, snacks and drinks were bright by every hour or so and the meals were plenty of food and tasted good. I was given a bag with eye cover, earplugs, socks, face wipes and ear phones. Entertainment was good as well. Qatar is an amazing airline. Wish we had something like this in the States!"

Pros: "All around great airline. Comfortable for super long flights and completely accommodating."

Pros: "I was stopped at gate check in and taken to one side as passport security had reported that I was intoxicated. I was badly injured in the armed forces and have lost my hearing which affects my balance. I asked for an aisle seat as I'm a big guy as s personal trainer. But was given seat E. Next to a huge obese guy. He slept whole journey, must of had nightmares and jumped and banged me repeatadly. I had the first meal, which was not great but edible. I couldn't eat it properly as I couldn't move my left arm due to the blob Sat next to me. I asked the stewardess to wake me at the meal times so I could get more food. She didn't. Not once. I couldn't even get out the seat to go toilet or get any of the help yourself stuff outside the toilets due to the fat blob I was put next too. Totally disgusted with the whole flight and crew when everytime I've used the same company before it was excellent."

Pros: "Excellent crew. Got on just in time. Last one on the flight but they were very understanding. Loved the airbus A380."

Pros: "Jumbo jet plane was fantastic."

Pros: "Very Very Good"
Pros: "Excellent service with very friendly staff. Everything ran so smoothly. For such a large aircraft I expected to have to queue up for boarding and exiting. No queuing, everything was so coordinated."

Pros: "Same as above"
Cons: "Same as above"
Pros: "Crew was excellent but seemed stretched ."
Cons: "Overall ICE was great but didn't seem to have many new films"

Pros: "Professional and friendly staff"
Pros: "The cabin crew were excellent. All of them. They gave me great service. It was once of the best long haul flights I've had in economy. Fantastic. I was seated in seat 80H. Please see to it that the cabin crew who serviced this area are well rewarded. If every flight had crew like these guys and gals then flying would be a lot more enjoyable."
Cons: "I really can't find anything to complain about."

Pros: "all entertrainment onboard is excellent ."
Cons: "the flight is good,,but unfortunately the staff is not accomodating that much,,need some basic training on what kind of food you are serving to passenger.."
Pros: "Attentive crew (Busines cabin was near empty). Highlights the deficit caused by large occupancy A380 Business cabin. A380 business cabin has been economy classed to within an inch of its life, too few crew and those that are on duty disorganised and stressed. 777 crew ratio was 3 crew to 1 pax :)"
Cons: "Engine noise. Boarding in Dubai was a farce as called to gate even though aircraft was severely delayed inbound. Surly lounge staff didn’t help. Business Class gate desk ‘closed’ even though staffed as person was busy on the phone. Weird 2 - 3 - 2 layout means window and centre seats have to clamber over reclined neighbours. Seat width better than A380 and also less tomb like when reclined to nearly flat bed."
Cons: "Crew attitude. Business seat was broken and they could have cared less. Business Class on A380 is a joke. Narrow seats, too few disorganised crew arguing amongst themselves and a bad attitude off at least three of them."
Cons: "The connection in Dubai was horrible. The 30 minute bus ride is so ridiculous. It's very difficult to even find the Business Class Lounge. No greeters. No signage. Terrible service. Even pajamas are not provided in Business Class --- unlike on Qatar Airways."
Pros: "Excellence !!!"
Pros: "Just about everything"
Cons: "Not much"
Pros: "The crew and flights were very good,I could not find any fault with them."
Cons: "I require assistance due to a spinal injury which makes walking and standing difficult but not impossible. When we arrived at Dubai I was told my name was not on the list for assistance even though I had been taken to the flight in a wheelchair and informed check-in and flight crew. The Emerates assistance people made it seem as if they were doing us a favour by assisting us,made us stand around waiting for a buggy then for the train at no time did they show any respect or compassion for the people they were supposed to be assisting."
Pros: "Assistance at Bangkok was excellent with no problems wheelchair all the way from flight to taxi. The assistance staff were employed by the airport and not Emerates which seemed to make a difference."

Pros: "food and Boarding"
Cons: "seats, I flight entertainment jacks were not working"
Pros: "Movie starts as soon as seated"
Cons: "No Emirate staff presented to due with the 20+ hours delay. Just sent their representatives who are not powerful to make decisions and at the end we have many questions not answered. Eg. Any earlier reconnect flights? Any alternative airlines? What is the checkout time of the compensation hotel? Any meal compensation if not staying at their hotel? Etc."
Pros: "The crew and the seat !"
Cons: "The food because of coronavirus the service was scaled back"
Pros: "Very comfortable overall"

Cons: "All fine."
Pros: "Food is not bad"
Cons: "The staff told us our carry-ons are over weighted and forced us to check in 2 carry-ons and charged us 250USD! Our carry-ons are totally standard-sized but just weighted more than 8 kg.

Pros: "Crew was very helpful & friendly. Cabin was well pressurized."
Pros: "Flight cancelled on whim of pilot due to a single faulty toilet."
Pros: "There is simply nothing to like. Whilst other airlines give peoooe a nice hotel room to spend the night on their trunk flights, Turkish airlines offers."
Cons: "I didn’t like anything not least the fact you make people wait in the station when they are on flights with stops. It Morocco offers a plush hotel room. I’m never travelling"
Pros: "I loved the amount of attention and consoling that was given to an ailing elderly woman on my flight to Turkey! On my flight to Ghana the attendants were so gentle and provided a lot of ammenities. Oh and the hotel was an amazing experience and respite especially after the run-around at the airport. Thank you"
Cons: "I did not enjoy the run-around I was given in trying to find the hotel desk. “50 meters then turn left” was the anthem. All someone had to say was go outside the airport and you’ll find the hotel desk! Hehe thank you Turkish Airlines however! Thank you."
Cons: "I could not use my ticket I was trying to extension date but customer services terrible"

Cons: "Old style lie flat (but not horizontal) seats"
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"
Cons: "No space"
Cons: "Not enough movie varities."
Pros: "Arriving safely"
Cons: "Seats horrible, food not eatable, poor service"

I was never informed why there was so much of a delay and in turn I had to pay triple of what I payed before for my flight. Very disappointed. Won't be flying this airline again. Service was rude. They should be more responsible when it comes to timing. We were on the flight waiting for two hours!!!"
Pros: "Every thing"
Cons: "I had my flight from London to Istanbul delayed and because I had connection flight in Istanbul to Russia they had to change my flight for the next day . That ruined my whole holidays and I had to go all the way home from Gatwick airport and next morning going again to Heathrow airport. No transfer or taxi was provided and No single apology from the staff or company . Very disappointed with Turkish airlines !"
Pros: "Many movies to watch. There are news channels like CNN to keep you updated with what las happening in the world."
Cons: "We had a connection at Istanbul. No laptop or notebook was allowed. A small portable charger to my iPhone was confisticated even thought it is smaller than my iPhone. Turkish TSA seemed a little confused with what to confisticate. They almost took away my portable shaver too. There were 4 little kids running around aisle during the flight forcing me to watch movies instead of sleep crossing the Atlantic Ocean."
Pros: "Great crew. Super nice to our 4 year old daughter. They were quick, extra polite and efficient. I'm usually quite picky but this leg was perfect."
Cons: "It was all good(which I rarely get to say these days on any carrier)"
Cons: "Why does Turkish Air boarding always have to be so chaotic - pushing and shoving, etc. Why cant TK control their business class space - people from economy always coming up for bathrooms when there are plenty in the back....."

Pros: "food is always good..crew too"
Cons: "less and less space in economy class for passengers not very kind boaridng people no info on posibble complimentary upgrade for Gold Card passengers"
Pros: "Better food and service than other airlines on which I've traveled recently. Loading passengers was disciplined and speedy. Staff very helpful. Istanbul airport is great for a long wait. If you go to a gate waiting area with no flight soon, you can stretch out and sleep. Good English-language bookstore."
Cons: "I have bought two sides ticket from Turkish Airlines. And i miss my first flight, when i came to airport for return flight Turkish Airlines cancel my return flight whitout update by email or massage by phon!!"
Pros: "I ve travelled many times on Qatar ,Emirates,and jordanian air lines but the Turkish was the poorest and the worst .A limited choices and little food ,and these people on the airplane donot do their jobs properly .I hope it will be better next time if there is a next time ."
Pros: "The entertainment choice and availability of USB port for charging was excellent."
Cons: "This leg of both of our flights (going and return) was quite cramped. Due to an unfortunate delay on our return flight, our overall day was extended from ~8 hours to 16 hours, and had us flying through the night--very unexpected and tiring. Additionally, although we requested kosher meals well in advance, the delay/cancellation of our flights and rebooking effectively cancelled our kosher meals and there was nothing for us to eat. This was very frustrating."
Pros: "Other than the late departure, everything else was excellent."
Cons: "Just the fact that we were some 40 minutes late, and this created panic among those passengers who had tight connections to Tehran, Tel-Aviv and Tbilisi. The rest was excellent!"

Pros: "Clean, orginzed, professional pilots"
Cons: "Too hot, few meal options"
Pros: "Service from the flight attendants were fantastic. The food was delicious and the entertainment included plenty of movie options. I'm also glad that my bags were never lost throughout all of my flights this summer on Turkish Airlines."
Cons: "I know seats in the 777-300 recline but do not disrupt the next row's space. That was not the case on the Airbus A330-300. It would be nice if the same seats were on the Airbus aircraft I flew from Istanbul to Bangkok."
Pros: "Food was fantastic. There were no delays. Very enjoyable."
Pros: "The crew were very polite, professional, and accomodating. The food was tasty even for airplane food. I was pleasantly surprised! There were tons of entertainement options to help pass the time."
