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

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

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

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!

It would be better if flight crew can clearly communicate in english. But they are kind and accommodating. Food is good, especially the sandwiches on the self-serving snack trays. They are better than the ones served. Boarding was organized.

The flight crews were extremely professional, helpful, and courteous. Departure and arrival times were accurate. No delay. I will use K airline again. Thanks

Staff at the airport wasn't helpful or friendly. Probably the worst airport experience I have ever had, going and coming. The staff on the plane was better. Still not super friendly or personable. However, they were not rude like airport staff. They ran out of certain menu items. Maybe could have been prepared better? Overall just ok.

the cabin was kept too hot. couldn't sleep as a result

Crew were unfriendly, touch screen for movies didn't work very well, seats were tight and uncomfortable

Awful seating. Bad food. Staff only have one bottle of water and no cans.

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.

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.

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!!

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

It wasn't good. I didn’t understand. They changed 320 dollars for 2 luggage. My ticket was regular and I paid almost 1200.00 dollars. Why they did charge? I want my money back.. thanks Yılmaz polat

My flight was delayed so bad i missed u it so i just said never mind

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Onboard staff was courteous, helpful, responsive and friendly. The boarding process was disorganized, poorly communicated, and disheveled. Gate agents were yelling instead of using the PA system, didn’t communicate the timing delay of our flight, and created an atmosphere of chaos rather than order and communication. As far as I know, there was no reason for their. I would hate to see how it operated under extreme conditions. I’ve never seen United Airlines operations in such a state.

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

No extra snacks were available. Meals quality is terrible. Crew was not friendly.

I liked that my son and I were reseated next to each other (we had different bookings). I liked that it was a directg flight and mostly on time. I liked that you provided pillows and blankets. Flight attendants were generally courteous. The messaging through wifi did not work well. The food was not good. Seats are very narrow and I felt slightly claustraphobic in the window seat.

We had turbulence ever 1/2 hr or so and the captains announcements were SOOOO LOUD

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

Beverage and food services are excellent. We enjoy paying the extra for economy plus for the 3 inches more leg room to be exact.

Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

Communication between the captain/crew and the passengers needs to be improved.

Food & service very good next I will pick up again

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.

I wish I had been able to choose a vegetarian meal. Crew friendly and helpful. Seat was ok. All quite efficient and pleasant. Would recommend for inner China travel for sure.

It was simply bad and on top of that my luggage hasn't been delivered until now. They can't even localize it which is just unacceptable when they are supposed to scan the bar code they put when we check in

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Loved and was pleasantly surprised by the food!! Request Lufthansa to help transiting passengers at Munich (confusion whether to go thru passport control or not).

Flight home was delayed multiple times, did not get home until 2am

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.

Confusing with Air Canada and United flight, it was a hell, no help, rude people there, stressful environment

Great crew and the plane was very nice! The problem was that we didn’t have WiFi on both of my flights. I found that to be very disappointing today when all the other airlines always have WiFi so I could work or watch a movie.

It was my first time booking from kayak and first time with Air Canada and I must say it was cheep and flight and experience was so good. My favorite KAYAK now🥰

Overall I will say it was a very good experience. It was as comfortable as can be expected for such a long flight - 12 hours from Toronto to Tokyo. Everyone was very pleasant and polite. Even the passengers were cooperative and trying to be nice to each other. Of course the space is limited on such a long flight. The bathrooms were actually very clean. The food was very good. I liked how there was a variety of food options. The in flight entertainment system was also very impressive! There were some children on the flight but they were well behaved and hardly ever crying. Great Job Canada Air! I will definitely fly with Air Canada again!

Flight was delay for 3hours then later canceled. I missed my work. It was a bit ectic and frustrating
