They lost my luggage on the inbound flight and then lost it again on this flight. I called online travel agent to change earlier flight to get a longer layover in Vancouver but ANA denied it

They lost my luggage on the inbound flight and then lost it again on this flight. I called online travel agent to change earlier flight to get a longer layover in Vancouver but ANA denied it

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.

Everything was excellent. Only the fish entree in the Japanese meal was overcooked and quite dry but everything else was great

Great first time experience on this airline. Very professional staff and great service.

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

I was able to change my flight last minute. It was more expensive, but that was my fault. Thank you for allowing me to fly!

Business class on ANA was awesome. There lie flat seats made it easier to sleep on a 12 hour flight. Food was great and service was excellent.

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.

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.

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.

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!

Plane took off on time and I had the whole row to myself!

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!

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

I traveled business class from Lax to Narita flight Jl61. The crew was attentive and polite. Food was good quality and service was as it should be. Narita to Bengaluru Jl753was another story in business class. The cabin was darkened for the 9hr:30min flight, food was mediocre, service was below standard and crew can't speak English to save their lives. When you ask for noodles soup from Ala carte they gave cup of noodles while Lax to Narita i was served the best Ramen noodles in a big bowl. Why the disparity on this leg of the journey.....or is it because there were mostly Indian passengers and it really did not matter to Jal to bother as its a poor country and Indians refrain from speaking up? A good airline but differentiation like this brings their reputation and business down.

Japan Airlines was excellent as usual once on the plane. Cabin crew was wonderful as usual. Boarding was solid on the Honolulu leg. For Thai Airways the boarding was less organized. I was in an earlier group but they weren’t clear with the numbers or instructions. Flight crew from Japan to Thailand was very good.

Terrible. Our flight was delayed by 15 hours. We lost a full day of our vacation.

highly recommend for trip to japan only reason why i gave good not excellent is because their selection of movies and tv shows in English is more limited .

We asked for Hindu vegetarian meal in advance and the quality of the food was horrendous. Never flying JAL again!

Japan airline is excellent service .I recommend to Kayak and Japan airline to Frend.

Overall a great experience. One complain was the vegetarian food that my wife had which was mostly boiled vegetables with not much flavor.

Very accommodating and kind airline crews. The plane is also big which makes the passengers more comfortable and relax

I actually didn’t make it onto the flight. I spent quite a few hours trying to rebook the flight just to get screwed out of $5000. Fun!

We booked business class round trip from Delhi to San Diego and back. On our last leg from Bangalore to Delhi we were down graded to economy class which was big disappointment other than that everything was great.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

The person I bought the ticket for didn’t make the flight.

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.

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

Same as last comment. Food sucks. Quality. Not surprising most people have no clue about nourishment Clearly

Not the fault of United—weather, reroute around weather, time sitting on tarmac, arrived couple hours late, too late for train into city necessitating a much pricier cab but weather…can’t be helped.

Friendly and professional flight crew. Aside from departure delay after boarding, easy flight and smooth landing.

Great smooth flight. Had a seating change, but that was an improvement. Thanks United Airways Crew.

I would like to get my money back. I flight was 4 hours late on the way to detroit, And same on my way back to Brussels they cancelled my flight and give me an other ticket and i had to wait 5 hours.

All attendents were very efficient, pleasant and happy. Everything went smoothly. The seats could have been wider. There could have been more free food instead of just one small bar.

Snacks were just placed and many people were hungry and unaware they were available. Ran out of water bottles. Attendants not available. Missed entire meal.

My seat was one of those that couldn't recline, but the problem was that it was abnormally upright, so the headrest actually made the seat concave, which was uncomfortable and hard on my lower back. I had to ball my jacket up and use it as lumbar support. goodness I had it with me.

Boarding was so so after zone 3 was called all other zones went in

I liked a lot , the flight attendant so nice ,the seat very comfortable I enjoyed the flight , I will do it again with Air Canada,

The cabin crew was professional and there were plenty of movie choices, but the food was a bit sub-standard.

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.

For goodness sake, board from the back of the plane to the front and assign overhead space. It would fix everything. Seriously.

Elderly female flight attendant was not customer friendly. There were only about 12 people on a regional jet that had about 60 seats. There were 8 exit row seats and none of them were taken. We attempted to sit in those seats and the flight attendant gave the standard " you didn't pay for those" so she would not allow us to move. What harm would that have caused ? They assigned seats to 5 of the 12 people in 2 rows, row 20 and 21. A simple friendly customer experience gesture of allowing us to sit in exit rows would have gone a long way in me having a very favorable impression on Air Canada. After that I have very poor impression of Air Canada and will not fly with them when I can avoid it.
