The crew was great. There was no wifi The cabin temperature got very hot Seat was uncomfortable

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!

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

Communication about delays was not very good. Crew and staff were excellent!

If they can provide a direct luggage transit line at JFK airport for all connecting flights, that would be prefect,

SAN-NRT was excellent experience with crew helping and assisting in all aspects of comfort. But NRT-BAN was not that comfortable with no blankets and pillows provided and treating it more like premier economy class. This has been the pattern I have observed where JAL uses non-trained crew, uncomfortable seats, restrooms not working, locking up window seats, business class comforts taken away on NRT-BAN route. Overall quality of service goes downhill on NRT-BAN flight. Not sure why?

I had a hard time checking in as my first and middle names lacked a space. The vendor spent a long time fixing it with the JAL. This should not have been a problem. Check in at ohare was good as Regina was very helpful and kind.

I booked with a traveling agency 1 year in advance. The company then changed our flights trying to shorten our stay months out from our departure that would cause us to significantly change our itinerary especially as a part of a larger group who had already purchased events for the trip. Not only will I never use KAYAK or ARANGANT again, I will never fly with American Airlines again. They did their utmost to ruin our first flight to Japan by turning every flight into an arduous ordeal. The flight home took 48 hours riddled with extended delays and multiple layovers. If you want to to ruin your trip use these companies that take your money and then choose the most inconvenient flights so that they can keep the profits for themselves. Worst experience is ever. Just book the flights yourself. The “savings” are not worth the headaches. Just delete the app altogether.

Dreamliner is an excellent aircraft. Great seats in business. Flight attendant Alex had a bored, sullen attitude in serving customers. Difficult to get his attention and very slow to respond to a simple request for water. Spoiled the experience a bit as the AA motto is “we’re here because of you”. Attitude needs some adjustment!

There was a certain guy in American Airlines his name is AAROON who tried to charged me for 246 dollars so I can fly from Dallas to DJT Palm Beach International Airport ; wherein it is not my fault why the flight is delayed so why do I need to pay ? I insisted my rights and told me to contact the company who booked me. But upon taking to Japan Airlines people they said upon checking I don’t have to pay additionally. So please check your people who does so things like this to passengers.

The best part was the staff. They are kind and gracious and made it a good flight.

Reasonable price, great service, highly recommended. i arrived well rested!

Since I traveled on my birthday, they gave me a gift and a card. How thoughtful and caring.

Paid for seat assignments that did not in any way match seats received, and had to upgrade at checkin

All was great on flight to Tokyo. The ROOM setup was very comfortable. Definitely will try to do again.

Long haul from Chicago to Tokyo was great, traveled in the ROOM on ANA and experience was great all around. The flight from Tokyo to Bangkok was fine. Definitely a good way to go. Should have stopped in Tokyo for a bit.

I thought I purchased premium economy but got an economy seating for an expensive airfare from Kayak. Not able to pay extra to upgrade at all

On time, food was great. Didn’t wake me up when they saw me sleeping and as soon as I used the toilet, they came up and asked me if I wanted dinner. Right on!

I was expecting to fly in a Japanese airline because that what I bought, very disappointed finding out the change of airline without any explanation.

Excellent. There were setbacks, but it had nothing to do with the crew. Mostly, mechanical which delayed our flight.

The flights with ANA were great. The flights with United, not so much.

It was so disappointed trip by unexpected company's fault delay. It had taken 3 hours delay for mechanical maintenance plus another 3 hours for bad weather.

SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

I need to note that this flight experience was generally fine but the boarding situation was absolutely a mess and there wasn’t any actual priority boarding. I rated the experience poorly because I’m am genuinely so frustrated with the crew on United taking the baggage space in first class. This flight it didn’t happen, but the last few flights (when I ironically don’t get an opportunity to provide feedback) have been spoiled because upon entering the first class cabin as one of the first few seated passengers, the overhead bins are full and ‘crew’’ tags are on the bags of those taking space. I don’t intend to infer some sort of a class or caste system but it’s absolutely ridiculous that the crew takes the overhead storage above and beyond their most loyal and lucrative customers. They should not even have economy space IMO. And I’ve gotten grief when I’ve noted to the crew the ridiculousness of the notion that the crew (who are the last off the plane) should have priority over flyers who pay. I hope you find a way to convey this message to United because it’s happening with increasing frequency and I intend to find a way to expose the specific crew members who are doing this on a flight by flight basis. (And I have a day job)

Great flight and crew. Need more legroom and DO NOT allow seats to recline.

Flight and crew were great. Need more legroom and do not allow seats to recline.

Bathrooms broken, Wifi not working, Direct TV stuck in a United credit card loop for whole flight

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Just sat on the run way after we arrived early

New Max 10, first class seats have been shrunk. End of a 20 hour journey, it was United not Lufthansa, just glad to get home

Both my flight where delayed Had 25min to make it to my transfer flight

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

Cabin staff were very disengaged, spoke with no eye contact, dismissive. Disappointing compared to my United experiences.

awful delay, awful communication, zero updates throughout the experience of a giant delay

It was decent, there was no WiFi on the flight but the FA’s gave everyone a warning once we boarded the plane. Unfortunately it didn't give me enough time to download my entertainment content.

On Time. AA is late due to maintenance all the time.

Seats were very tight for a 17 hour flight. Baby cried for 15 out of 17 hours.

Both directions of our trip were befuddled by massive delays, one of which led to our connecting flight being grounded mid air due to storms that we’d have missed if we were on time. The other our originating flight was delayed repeatedly until it arrived at our connecting airport later than our final leg was even supposed to have arrived. American cannot seem to manage rebooking s for a family party… both directions we had to come up with a plan to get to Boston stay overnight only one night each direction was covered by the airline -and take a bus to or from our destination. Missed an entire leg of our trip, hotel cancellation fees, expensive stay in Boston and bus ticket expenses are unlikely to be comped and the meal vouchers are worthless.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.
