Staff show very stress with delayed flight more than passenger.

Very good service and food. Crew was professional and considerate. Cabin and restrooms were kept clean

Flight Attendants could have been nicer and food portions could be bigger.

Great experience, comfort and food is delicious. Always great service and one time

Excellent service from check in to boarding the crew is so pleasant to asked

The food from Los Angeles to Taipei made me throw up. The flight is also not comfort. But the staffs are very friendly and nice.

Everything is good staff is polite and helpful flights are on time sub sandwhich for a snack was good with a bottle of water only thing maybe more variety of food like breakfast or dinner depends on the time

I appreciate the email reminders for online check-in which made my entry to the lines less stressful. The flight was on schedule and on time. The baording staff were proactively helpful and approachable. The airplane inflight food, entertainment and comfies as well as provisions are excellent even in the economy seating. The airline transfer was smooth and easy! Luggage safe and intact! Thank you EVA airline for making my trip a reliable safe and comfortable experience.

I was sleep when they brought the food. They had put a note on my seat. There was no food when I asked for food later. There was just one main meal served in this 14 hours flight. They offered me sandwich with ham which I don’t eat since I am pescatarian. Long story short I had to wait to get to TPE to get something to eat. I am extremely disappointed from the service. I have been flying EVA since I was 1 year old. Perhaps no more EVA for me. Seems EVA glorious day is long gone

Except for crying babies all was ok although the movie selection wasn't the best.

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.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

This flight was a superior flight in all regards. Extremely pleasant experience.

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

Warm the bread. Movies: better choices to include Chinese movies options or some of the older winners of flim festival

Almost 6 hours of delay with over 12 gate changes. Flight was supposed to depart around 6 and instead depart after 12am. No accommodations were offered than some snacks closer to midnight when the crew was planning to throw away some snacks.

The crew was very nice and polite. They made sure everybody got their meal and drinks. Even the economy class had a very adequate leg room for someone that is over 6 foot tall.

Purchased WiFi was slow to non functional. Staff was not personable or friendly. Seats were cramped. Boarding took long but I expected that.

Luckily I just tried to sleep. But the entertainment system was awkward to operate. I hate all this stuff with apps and adding it to your phone and all. It is a nuisance. I would prefer a good magazine or newspaper in the pocket in front of me or available.

One of the best 14 hour flights I've ever had. Crew was friendly throughout which can be difficult on longer flights. The crew being kind and respectful is very important for me. Plane felt clean and I was able to get some well needed uninterrupted sleep. I put them slightly above Cathay Pacific as far as cleanliness the only down side was a lack of entertainment selections, but hey I am an American taking a trip on a Japanese airline so I cannot complain. Thank you ANA and the Tokyo airport all very friendly. Will see you soon

Poor. We weren’t able to check in online (for several hours until we gave up) for no apparent reasons although our passports were loaded successfully. When we were at the airport check-in, a rep helped us at the kiosk but she disregarded the KTN provided to her so we had to come back for it after being questioned by the TSA person…

ANA gave me an amazing experience. They are very good with customer service.

Everything was good may improve some alcohol drinks and amenities during fly

The crew was amazing, really friendly and efficient. One of the best flights I have ever been on. They made the long flight comfortable and I noticed there were two birthdays on the flight. They gave to customers birthday cards and wished them a happy birthday. That was very nice to see.

I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.

Cabin crew is very helpful and nice, it is another level of service compared to Air Canada

As before, my only problem was not being able to download my boarding passes prior to arrival at the airport. Everything else was perfect.

If I had blood clots, that window seat would've killed me for certain.

Short staffs, I ask stewardess to bring me cognac twice during dinner but they didn't bring it!

I had high expectations but met with a below average experience. I hope the Airline will take a notice and improve.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.

Worst experience I have ever had with any airline in over 25 years.

Everything was fine and I have no complaints or things to note.

Rude staff. I would avoid using the word racist but definitely partially or discriminatory. My 72 yrs old mother who is also disabled was traveling on this flight. She was the second passenger boarded to the plane. The First elderly couple ahead of my mother were allowed to use the airplane bathroom but my mother was denied entry stating it was for safety reasons. My mother objected the the couple in front of her were allowed but hostess still stated that due to the flight safety reasons she can’t use it. Even my mother explained that he is using blood pressure medication that’s why she have to use the restroom frequently but the crew continued arguing her. At one point the Mae attendent even suggested that if that’s the case my mother can urinate in her seat. The level of disrespect against an elderly lady is beyond my comprehension. This matter will be taken to the social media to shame the employees involved.

my experience was great with Turkish airlines . the problem i encountered was with kayak booking. When I booked . it showed that im allowed a bag . and when I got to the airport, i had to pay $165 for one bag.

Not up to Business Class standards. Two of the three toilets were out of order. The hostesses were aware and didn’t show any responsible act to do something. Food quality was not what we expect from Turkish hospitality. Overall we were not impressed and disappointed.

During mid flight, try to get a flight attendant to help I couldn’t find one Otherwise, everything was perfect

I was not given basinett seat.The connecting flight was missed due to airline fault i was not accomodated for hotel.Drinks were normt served frewuently.Never travelling again on tirkish airlines.I always travel wiyh family by turkish airline but no more.zero stars

The crew were very hospitable and pleasant. The food was pretty good. Unfortunately, there was a flight delay of more than 2 hours. We're not sure why but it appeared to be outside the control of Turkish Airlines.

Bough tickets with luggage, but made me pay at Airport as well

The economy seat was so uncomfortable, had not enough leg room for 13 hours flight, front seat basket was broken and couldn’t hold anything, food quality was horrible( we got food poisoned ) we charged for logged which used to be free. We paid too much for this flight and very disappointed. Turkish air line better to make satisfy and respect people instead of find different way to scam people.

This is really the rating of two flights. JFK to IST then IST to NQZ. New York to Istanbul was good. Good crew and all positives. The flight to Astana was so bad that brought it all down. Crew was nonexistent above the minimum, seats were cramped, and it was hot on the plane. Turkish Airlines seems to be slipping down to US based carriers level.

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.
