They didn't tell me they changed my flight. So I got confused on what happened to my flight.

It was good overall. What I liked most was the restrooms. Compared to other airlines, the restrooms seem larger and look clean. The seats also look clean. The attendants are nice, except one time during the flight. I was sitting on aisle and a man sitting window. He asked an attendant for a snack. She told him to go ahead and get some snack from the section with food storage (I am not sure how it is called). So, I had to get up to let him get out from his seat. Why she did not bring him some snacks so that I would not have to move, I do not know... I was kind of surprised how inconsiderate the attendant was.

JOKE of a company with the most Ridiculous policies. JAL is amazing, KAYAK/UNDERPRICER is the worst company I have ever dealt with, NEVER AGAIN

Overall, a solid flight experience. Boarding was quick and efficient, even with a full and overbooked flight. The flight crew did a great job providing attentive and friendly service throughout. I flew in economy, and while the seats were acceptable, they could definitely use more cushioning, especially for a 14-hour flight. By the end, it was quite uncomfortable to remain seated. Legroom was also limited, particularly with a bag stored under the seat and the passenger in front reclining. That said, everything else went smoothly, and I appreciated the professionalism of the crew.

The flight was delightful overall. The check-in and boarding were on smooth and on time. Amenities and staffs were elevated. However, if glasses were served instead of cups, there should be a complete premium.

Sure I would’ve liked a little more space, but it was better than economy. I bring my own food because I have food allergies it would be nice if they offered larger salads or more vegetables instead of starch it was really a good flight. I don’t wanna complain. I’m grateful to fly at all safely. Thank you to the pilots.

Flight crews are very attentive and polite. Cabin and toilets are clean. Food is above average for economy class. We missed our connecting flights because the first flight was delayed, the ground crews at Tokyo were very helpful, providing all the information and support (including cash for our train ticket) to get us to our destination. Very impressive. No wonder they are always at the top ten lists.

Excellent! So happy that the crew members were so helpful and friendly and able to understandably communicate. They’re very receptive with someone like me, with disability. I love that I did not even have to ask for luggage help like, having to place and take down my carry-on luggage in and out of the over-head compartment. Hope, help is extended to disabled passenger(s) through out class classifications they’ve bought; economy or business class it might be. As a disabled person myself, I’m truly of great appreciation of this kind of help. Means a lot !!! Thank you so very much JAL crew. You out done others on this customer service part of the trip. Please continue to do so. From now on, I’ll choose JAL as my airline whenever I have to fly to any southeast asian countries. And I will disseminate my excellent travel experience with you to others.

American Airlines food is horrible. Also, paid to fly JAL on all segments, but received a much lower quality. I was disappointed to learn that we would be using American Airlines on this flight, which has less comfort, entertainment, choices, and lower standard of service. Overall not satisfied.

Food was very mediocre. Economy is pretty uncomfortable. Crew was excellent and responsive.

UA discouraged people to choose seat on economy class by charging about three times of another airlines. For example, ANA will charge USD60 to choose an aisle seat but UA is charging USD 219.

Roomy airlines. Friendly staff. Timely service. Temp was warm during the flight.

On time. Convenience of a small airport. Excellent service from staff at check-in.

LAX to San Francisco under UA was sooooo stressful! Flights was delayed and no assistance from the airline to the next flight. Flew UA twice and both flights highly distressful.

The food was terrible and totally inedible. If you are flying with ANA/United bring your own food it was a long flight to be hingry

I thought I bought the ticket directly through Kayak not a 3rd party

I like that we made it faster than regularly scheduled. Everything else was poor. The boarding was slow and chaotic. One person was screaming instructions to people that didn’t understand and there was only one camera so boarding was slow. The crew was not very friendly and one stewardess was extremely rude to everyone the entire flight. The food was not good and not themed to the country we were going to like every international flight I’ve taken. Lastly the seats were awful. After this flight I would never recommend United and will actively avoid booking another flight through them.

When I checked in, it printed two bag tags. The helper said they would cancel the other. They canceled both and my bag was left behind

It was really fast to Tokyo. Much faster than the budget carriers. However a lot less space than international flights.

The ladies are great seats should be a little bigger!

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

I thought the service was very nice and pleasant. There were no hiccups and no issues so overall a good experience.

Very good flight. Crew was great. No issues and we even arrived early.

The flights are constantly late anymore, and they won't even give you a glass of water on the plane. For years, they were able to do a service on this flight from Atlanta to Knoxville and Knoxville Atlanta now they say it's too short of a flight. You can't even get a quick drink of water.

Flight got canceled 4 times, missed my connecting flight due to delays, have to wait to go home tomorrow

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Great experience nice pilot very soft and easy landing and take off

We sat on the runway for over an hour before departure. That was unwelcome.

Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

It was Swiss. Our kosher meals were literally frozen solid and therefore inedible, and the crew didnt care.

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

We used Kayak to reserve our tickets and specifically checked the luggage option which was a more expensive option. When we arrived at the terminal we had to pay an extra $90 per suitcase for the three passengers. This has been a pattern for the past 3 years. Why charge for a more expensive luggage option, and the ticket price not include luggage?

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

My experience with American Airlines was great. Unfortunately my stroller was not located and has not been given to me and or reached out in return for in regard to information.

Pilots were fantastic - super smooth. First Class flight attendant was very attentive. Main Cabin flight attendant should try to smooth the rough edges of her voice - very shrill / punitive. Hurt my ears just to listen to her. Recognize they have a (tough) job to do - but tone over speakers needs to be less like scolding a 5 year old.

Maybe focus more on delivering a good product vs selling me a damn credit card

American Airlines is a great dependable airline, on time arrival and departure with polite crew and staff.

I think since I am an AA Advantage member, my checked bags should have been free, but I paid for all 4 of us.

This flight moved Gates several times in a short time period, from B to C, which required a substantial walk or rail ride. Then the flight was delayed more than 2 hours and the food was subpar compared to other flights.

Flight was delayed multiple times without giving any particular reason and the only thing that was communicated was that 'Aircraft is getting ready'. I was stuck at SFO airport for 15 hours and finally took Southwest Airlines flight back home to Dallas.

Hydraulic leak caused the flight to be cancelled. Auto system scheduled us on a 3 am flight. Wevhsedvrebook on the app and hit schedules later in the afternoon. Our luggage per gate and ticket agent would be rescanned and put in our new flight. Did not happen. Our luggage stayed in hsv. Baggage claim in wash dc unable to help. We filed a claim. Several emails about our luggage were in conflict with one another. Called as baggage and was on hold 30 minutes. Oscar said one of 2 was out fir delivery then cancelled. About 45 minutes later both pieces were delivered. Their system is suspect

I was not clear if food was offered or not.

Because I bought my ticket from Underpricer, I could not check in online. I could only check in at the airport and that was deeply frustrating because I had to arrive very early. The flight also departed 45 min late and passengers were given no explanations about why we were delayed. I was worried I would miss my connecting flight. Once on board, however, the flight was fine.
