Everything was great, however the seats in the back are very small. Not as Comfortable as I would have liked.

everything was so good! Especially Food. It was the best I've ever had! However,I requested to add mileage point to Star alliance group ANA; it hasn't been added yet.... 😞

The crew very accommodating and food too is good. Keep up the good work

The crews are very efficient. Other airlines should learn from them when it comes to boarding and departing from the airplane. They also display efficiency in serving meals. They don't keep the aisles blocked for hours like some other airlines. The food is poor. Generally the food was unrecognizable and poorly prepared. The only thing that made it better than US flag carriers is that there was a fresh fruit bowl with each meal.

Awful had to ask for a supervisor to sit with my flight companion even t booked the tickets together weeks before

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

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.

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.

Flight was good and comfortable, even for long haul economy. No complaints.

Checking in via an alliance partner, even a foreign one should get TSA Precheck printed on your boarding pass. The paper copy issued by ANA didn’t show it. I couldn’t get my digital copy due to some technical issue arising because I checked in with ANA. The kiosks at SFO similarly threw an error. The only way I could have gotten a new copy of my boarding pass was from the UA counter and lines were nearly as long as TSA so I bit the bullet and went through the regular TSA line. If UA wants my business, they need to improve that process.

Suite lounge in Honolulu is very exclusive and boarding from the lounge into the plane is unique. First suites were huge and comfortable. Japanese meal is like a high end omakase meal. All the staff were very kind and provided sophisticated service. Fast Track upon landing was appreciated but not needed this time because immigration was so empty and easy.

I like the service very much. The food just okay but maybe different culture who like, who don't like.

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.

Overall it was good. Making changes to the reservation on ANA’s website was little challenging. Would like to see those features improved in the future.

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.

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I prebooked a comfort plus seat on this flight and therefore the flight was comfy. I got the correct seat in the correct section of the plane that I have booked, that's this. Flight was comfortable. Staff were average on the flight, appearing to be rushed and short in engagement with travellers, perhaps this to maximise there rest time on the flight.

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Crew was excellent. This was a relatively long flight though and had very little leg room, and no entertainment.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Staff members were not helpful they ignored all calls for an attendant.

Flight was delayed and missed my connection Lufthansa didn’t respond.

the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

Overall it was good. I missed my connection but I was put on another flight.

Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United

Overall it was good. Food was bad. I ordered gluten free vegetarian meal. But I got gluten free chicken for my long flight from Seattle to Istanbul. I don’t eat any kind of meat. Second meal I got eggplant with meat which I couldn’t eat. I don’t understand why we can’t get gluten free vegetarian meal for a 12 hour flight. I eat the bread and that was it.

Worse worse worse, i would not recommend this airline to anyone. Istanbul airport maybe State of the Art facility but staff is rude, only works if they get tips, and they push you to give tips even though my family had spent $50 in tips. Airline staff doesn't speak english so you really can't understand them. It was a nightmare travelling with Turkish. Never again.

As a big guy the seats are way too small for me. Would prefer more comfortable seats on these long haul flights.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!

This is my 2nd time with the Turkish airline. Would definitely recommend. In stability we connected to Indiago would not recommend, very cramped seating. No inflight entertainment..service was inferior.

I wouldn't know what the flight was like. AI canceled my flight reservation!! There's no way to speak to an actual human to fix the issue! NEVER AGAIN! ALWAYS BOOK YOUR FLIGHT DIRECTLY WITH THE AIRLINE NEVER GO THROUGH KAYAK OR JUSTFLY.COM!!

Paying extra for premium seats was wasted. Turkish Airlines takes 2 seats for bassinet. The lady next to me had a baby with bassinet Bassinet was in front of my seat

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.
