The business class is excellent. I loved the food, and the crew was very attentive and professional. From boarding to arrival, everything felt smooth and well-organised.

The business class is excellent. I loved the food, and the crew was very attentive and professional. From boarding to arrival, everything felt smooth and well-organised.

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

Great service and comfort level. You can have more of vegetarian food options.

It’s great, long flight and arrive safe at destination

Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

I can't believe they put my wife and I in the two middle seats! It is a very long flight and we had single flyers on either side of us blocking the way to the bathroom! There's no reason to not give one of us the isle seat so we could have managed bathroom needs and snacks with convenience. So I think very poorly of Korean air to put us both in the middle, I've never had that happen before and will probably avoid this airline in the future because of this. We tried to have them change it but they didn't so you pretty much lost a customer because of it.

One of the flight attendants stepped on my foot. I was on the aisle seat. A lady inside needed to get out. So Instood. Just then, a flight attentendant came wuicklybtheoughbthe aisle and stepprd on my sock covered toes. I let out a small sound. She stopped momentarily, but didn’t ask how I was just took off of the aisle. Never came back to see how I was. Fortunately, I was not really hurt other than a slight soreness in my toes. But I found that to be very negligent.

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

Good. Obviously there is a slightly condescending attitude of all American workers towards their customers but other than that all good.

Food was surprisingly good for airplane, crew was great, though announcements were sometimes hard to hear. Plane was nice (had great headroom, large screens and big dimmable windows). But seats were uncomfortable in economy (seat width was fine, but not enough shoulder room). I wish I could use my person Bluetooth headphones with screen( I think I could mirror it on my device, but didn’t want to keep tray table down to hold it up).

If I had a chance to rate Turkish airline in negative I will definitely give -100. Worst non professional attitude of ground staff at Istanbul. If I was a owner of Turkish airline I would definitely fire all check-in staff who was on duty for this flight. Rude attitude to all customers. Non availability of food options. Chicken and fish option was finished within 8 rows and only pasta was available (seat rows 25- last row). Seat Front glove boxes were ripped and all stuff was dropping on floor. Flight crew was trying to pacify the customers but this is sole responsibility of the manager who arranged / booked the food for this flight. He must be removed from this position as he has no idea about his job. It was worst flight during my whole life. Never booking again on Turkish airline.

Bussing in a major flight is idiotic. Cabin was too warm. Food was bland and felt old

Crew attendants attention to the travelers. Good food. I always fly with Turkish Airlines

Tv didn’t work and left the gate late but everything else was perfect.

Again poor use of old aircraft and old business class seats that show there age.

Service and food were very good, I liked it a lot. I liked the little gifts we all got , but I don’t think I’d fly on Turkish airlines to go to New York from Istanbul or from New York to Instanbul anymore. Flight is way too long.

The crew was awesome. My husband fell while traveling to the WC and got a head abrasion. The crew helped him greatly and a physician that was also on the flight checked him out as well. They all get an A+!

Same as before boarding process and lack of crew experience in the process

Excellent service. Made United 's business class look like a cattle car

One hour before landing was the most scary part of my life. The plane just dropped from the air . No explanation or apologies from the captain. Women and children screaming everywhere. Would like to know what happened

My flight going to doha had economy seats that had a little more leg room. Coming back the leg room was not there. I'm 6'3" and my knees were against the chair in front of me. I couldn't slide my feet under the chair. The 15 hour flight felt like torture from the lack of sleep I was getting being so uncomfortable. Food and crew were great though.

It was excellent except for at the very end. I woke up about 1.5 hrs before touchdown and wanted to order food in the Business class. I was told they had shut down food service. It would have been good to get a heads up before they closed the service. Anna the air hostess was wonderful. She did get me 2 bowls of fruit and I was very appreciative of her. Wonderful human and a hostess.

Amazing airline accommodations. The cabins were so great. The food was very good and the flight attendants were so nice. Made a 15 hour flight seem easy.

I paid extra for seating when first booking flight to be in a comfortable economy seat They still changed it to a middle seat regardless. When I asked for it to be changed back to aisle, they could only give me one at the back of the plane in the least comfortable seats.

Same as already mentioned. This was more comforting as I got my aisle seat for my knee.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

Qatar Airways is an excellent service provider. The crew members were attentive and helpful. The aircraft was very clean. This was the longest leg of our journey, so it would have been nice to have more leg room for comfort. We appreciated the crew's service of four hot meals to all of us during this long flight. Also, it was helpful that the crew asked us to keep the window shades down for the entire journey, allowing the environment to get lots of rest during the trip. For families traveling with little children, this was helpful to them to keep them settled.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

It was very good. It was a long flight and being a tight with little leg room.
