Cons: "wifi wasn't good - I couldn't connect. Wine choice wasn't good (white). Would have preferred a sav blanc"
Pros: "Did not get drinks at all until dinner was erred which was over 2 hours into the journey. May have been ok if I hadn't just run from a late arriving connection to make this leg of my flight and I was so thirsty!! Naturally they were out of what would have liked for my meal. However the worst part is that Mt luggage didn't make it to Heathrow with my flight and the service in trying to get my bags back has been shocking. Considering I was told my bags would be arriving in London 2 hours later I still do not have my bage in my possession- a day and a half later. And trying to get to talk to someone to help. This has been so frustrating and disappointing."
Pros: "Entertainment Food Friendly Flight Crews"

Cons: "The crew wasn't as attentive to me as they were to the gentlemen on the plane. Felt a ignored quite a bit."

Cons: "1: This is related to HORRIBLE experience traveling to Dubai from Ahmedabad on Saturday (EK 202 11 PM/ EK 538). EK 202 – delayed by 24 hours Issue:FROM 3 HOURS INFLIGHT SITTING, RETURNED LUGGAGE, HOTEL FOR 4 HOURS, 12 HOURS OF WAIT TIME ON AIRPORT DOING NOTHING EK 538 – delayed by 6 hours Issue:FROM 3 HOURS INFLIGHT SITTING, 6 hours delay. I booked the flight with Emirates because of their better service even though Price doesn’t matter, but I didn’t expect this bad. No rest from Last 48 hours due to HORRIBLE experience with emirates and Flight delayed. I am surely looking for some king of refund in the ticket since it was really bad experience. It took 48 hours to reach from JFK to AMD (It supposed to be 20-22 Hours). Do you think Should I fly with emirates Again? If yes give me One reason. Thanks. Any feedback appreciated."
Pros: "The 380 is a great plane, the quiet and comfort."
Pros: "Cosmetics kit is of high quality. Airport pick up and drop off."
Cons: "Seats are not wide enough and uncomfortable for business class. Not many food options. TV remote is not intuitive. When seat is turned into bed, it is not 100% flat, and has some elevation. Cannot comfortably speak with co-passenger due to privacy board that doesn't come down fully. TV positioning is not ergonomical and co-passenger's TV screen is too bright when trying to sleep."
Cons: "The complimentary food coupons don't clearly mention what is covered and not and it is a hassle to figure out with airport vendors on what the meal means when there are a lot of options. If the voucher also has a dollar value it will make it easier to know. The Indian restaurants at Gates C should be taken off this list. They were rude and generally left a bad taste in the mouth."
Cons: "Had a tough time to get a replacement ticket."
Pros: "the entertainment was great and I love it."
Cons: "Too cold!!!! When asked for a blanket, crew members gave excuses to why blankets are not available; however, other passengers had multiple blankets. Due to the unorganization of the crew, I had to keep paging for attendent only to be forgotten again. Boarding was not controlled. Passengers gathered around boarding attendant which made getting through zones frustrating. For the amount of money paid, I was hoping for a much better flight."
Cons: "The technical problem with flight from Dubai to Dulles could have been resolved before boarding the flight. Crew could have been more clear on how much longer it would take to resolve the problem before and not after boarding the flight."
Pros: "Hospitality and maintenance of timings"
Cons: "May be you can give priority to senior citizens just like those with kids"
Cons: "At the Istanbul airport an item was taken from me for no reason. No regulation was shown for that item to be taken. I wasn’t comfortable with the way I was treated at the airport. The flight was very good"
Pros: "The Turkish Airline crew are treat you as guests not as customers."
Pros: "It was a great flight."
Cons: "The cabin temperature was a little warm"
Pros: "The service"
Cons: "No entertainment. Late boarding."
Pros: "I have flown Turkish Air many times since 2010, and used to like the airline. Not so much anymore. I would say their entertainment center and food are pretty good."
Cons: "They used to have an affordable Economy Premium option, now all they have are seats made for someone 5’5” 150 pounds. Anyone over 6’ can and will suffer greatly. I’m 6’4” and fly many of their 12 hour flights from LAX to Istanbul and have to sit sideways, until my back aches so bad I have to turn. They also keep their planes unbearably hot, which I have no idea why, making the trip in that cramped seat horrible. Their in between meals snacks consist of cheese sandwiches, and the attendants never come around with drinks or snacks. I also fly Singapore Air and Emirates and their service is subperb!"
Cons: "The crew on board was aloof, and somewhat rude. I was traveling with my 87 yr old mother and they did little to help, especially when we needed the restroom but they had the aisle blocked for most of the time, serving food. There was no way to get around to access the bathroom and the crew turned us away from the only available bathroom in the front. Really?! Not impressed at all. Also the flt was 30 minutes late making our connection tight. One of the young, gorgeous stewardesses was rude and dismissive of me when I asked about it."
Cons: "Plane delayed Missed connection"
Cons: "Departed over 1/2 hour late making it necessary to make a mad dash for the next gate for the following flight."
Pros: "On time."

Pros: "Comfortable seat. Food acceptable."
Cons: "Computers were down for more than 2 hours. I have a disability and I was told to seat and someone would come with a wheelchair when the problem would be solved. They completely forgot about me. When I saw that the people had boarded, I went to the counter asking for the wheelchair. They sent me to Egypt Air to request it. Of course Egypt Air said I was not their passenger, so I should request the chair to my airline. I tell the man from Egypt air to talk directly to his colleagues in Turkish Airways. He is angry and tells me he's doing me the favor of getting the chair even if it's not his job, so i should be very thankful. He requested the chair and sat me on it. Kept telling me I should be thankful to him, even if it wasn't his job. Turkish Airways never got the wheelchair for me and I have mobility problem but they tell me to get to another airline to get it! No entertainment originally in Spanish in any flights for Spanish speaking passengers."
Pros: "Short flight-everything fine. Great plane."
Cons: "Having to pay for internet if you want to use it. The way Israelis queue at the airport, leaving no room between you and them...too much pressure. Strange 'breakfast"."
Pros: "I was upgraded to buisnes class :)"
Cons: "Every thing was ok"
Pros: "Awesome service, comfy business cabin!"
Cons: "Boarding in Istanbul and Tel Aviv was chaotic, no business class boarding. Checking laptop in Istanbul was inconvenient. Lounge Istanbul was awesome however way too crowded to fully take advantage of it. Also should control people and what they takfor food. The lines were long and people would literally pile their plates with massive amounts of food, take it to their seat then leave it. Fix the lockers and add more, they are a wonderful asset but I was not able to take advantage of. Consider limiting access to manage crowds."
Pros: "All aspects of the flight were flawless. Lounge in IST is always a great addition."

Pros: "The lost my 1 checked bag of luggage somewhere between tel aviv-istanbul-frankfurt!! Filed a report at Frankfurt Airport but it was filled with all my essentials and some valuables and the airport staff didnt seem to concerned in helping me.... To clarify, my experience through Kayak has been fine! However this whole ordeal has left a very sour taste in my mouth...i still dont have my luggage. They couldnt track it l yet....maybe you can help or forward this message to the appropriate authority. It is extremely important to me :/ Thanks, I still like kayak :) -addam rhodes"

Pros: "Things that I liked I expected - we take it for granted: crew must be polite, boarding - efficient, leg room is normal."
Cons: "Even in business class leg room is not ample, aircraft seems to be quite old, inside is well scoffed and scratched, my foot rest couldn't be raised or extended, no personal ventilation, temperature is interchangeably too hot or too cold, movie choice is far from awesome"
Pros: "Very nice service"
Cons: "I flew from Tel Aviv and upon arrival went through security so I could proceed to my departure gate. Then at the departure gate a whole new round of security. There was a priority line, but for some reason I didn't get in it, although I fly business. The line was not that long but it just did not move. And the a/c was not working. Worst boarding experience ever and I've been flying for over 40 years. When I boarded finally I asked if I could give a review and although they said yes- nothing. So I hope someone who cares sees this."
Cons: "I was shocked when we landed in Ataturk and the sleeve was attached to the plane we had to get down to the ground from the middle of the sleeve. We were taken to the terminal by bus!! After the sleeve was already attached! I can understand when you are in some small airport or flying with low cost airline. But it's Turkish airlines in their home airport! Really disappointed."

Pros: "Food is fresh and tasty. Safe landings and overall flight experience is very pleasing."
Cons: "I had paid for an upgrade to sit in the front of the cabin with extra legroom (row 14A). When I boarded a man sat it my seat. He had not paid for the upgrade, but the crew let him stay in my seat. I had asked him to social distance but he continued to sit right behind me bo matter which seat I moved to. He argued with the crew until they gave up and let him stay. They did not check his boarding pass or ask him to move to his assigned seat I found a different seat away from him but I don’t see the point in paying for extra legroom when the crew let’s people who haven’t paid for it sit it those seats. I felt harassed by the man and was very uncomfortable the whole flight. I am considering my next step, I think I should at least receive a refund for the upgrade I paid for."

When they arrived on Amsterdam Netherlands Airport they were dropped to the gate assigned first and once the gate changed on the fly no body came to help them moving to the new gate assigned which was far away to walk. Nobody even came to tell them that the gate has been changed. It was because of my father's alertness they didn't miss the connecting flight and when my father asked help to members on airport none of them helped my parents and other 4 co passengers which also were on wheel chairs. It was so scary experience for them that they asked me not to book any more flights with Jet Airways. I won't recommend Jet Airways to any of my friends for their parents to travel to USA. I strongly recommend you guys to take a strict action against this. This is so unacceptable."

We were traveling with 5 kids including an infant and we were not allowed to board until we found the receipt. I thought surely they would have record that I had paid, but I guess not.
