It was amazing. Japan is lovely. I hope to go again. Thank you for everything.

My first issue is the lack of clarity with the airlines. I know that Japan airlines and American Airlines are partners, but I couldn’t figure out which airline I was flying with. I got the flight info for Japan airlines and ended up on American. After my Kayak booking (via Underpricer) I got a phone call to see if I wanted up choose a seat and pay for luggage fees. both American and Japan airlines offer 2 carryons and 2 regular luggage checked in at no additional fees to Tokyo. Having already done my research, I opted out on their “Offer” and just contacted the airline directly to pay for upgraded seats (Which were cheaper than the Underpricer deal) My top complaint was the flight delay from HND to LAX it wasn’t until I had already made my unchangable airport drop off car reservations , that I received 3 hour flight delay email. I was forced to be there 6 hours prior to the departure. They were kind enough to give us a limited restaurant food voucher- which was 1900 yen ( I saw Delta food vouchers were 2000 yen). My teen and I ate food court pizza. The flight arrived when expected, The food was mid on the flight. I slept and woke up about 1.5 hours to LAX. I had waffles ( which also contained 1 mushroom and 1 tomato in the same tray) and 3 small pieces of fruit. All went well, just remember to check on your 3rd party ticket companies. Some seem to be sneaky All in all it was a very long day, we made it back safe.

Horrible like always, flight was supposed to be at 11:40am, we ended up getting a different airplane at 3:25pm.

I have been flying with JAL a few times, crews service, food, overall comfort even with economy, I would rate it the top three airlines. None of any American carriers can provide such excellent service.

service was excellent. crew very polite, courteous, and good service especially to passengers like me who is a wheelchair passenger

First of all it’s an American Airline flight not JAL as advertised. Code share is deceiving. Seats are uncomfortable. Stewards in our section were not friendly, felt rude at times.

Lovely flight attendants comfort in Economy Premium. Very attentive and kind I would choose JAL again for sure!

I enjoy flying American airlines. I tried to book American airline when I’m flying most places.

After boarding it was fine. Premium economy was not available for one long leg. Economy was very uncomfortable. They need to fix these issues. Planes are old. It gets more and more dangerous due to fatigue of plane parts. They need to upgrade before something goes wrong with the plane. Hazardous. Hari S Doss

Nice amount of space in economy seat. Very attentive attendants that allowed a seat change that helped several people. Morning meal could have been better.

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

On the Qantas flight, I could barely hear some of the announcements. It was better when I could read them on the screen.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

Our boarding and flight was very good. However when we landed and pulled in to the gate it took 55 minutes for the jet bridge to be positioned next to the aircraft. That caused us to miss our ground transportation and it caused us unnecessary last minute transit planning and expense. Our flight was AA1733 on March 17, 2026

We booked with Qantas instead of Delta and we instead flew on American Airlines. American is not our favorite to go on. No leg room and the width of seats are a joke. Your are packed like sardines on American flights.

My experience was great overall. Tanya was particularly friendly and helpful the entire trip. I was very pleased with her customer service skills. The plane was an older aircraft but the entire way was comfortable with barely any turbulence at all. Qantas should speed up its fleet renovation. Totally recommend using this airline.

When I originally booked this flight, I was expecting to travel on Qantas. When the itinerary changed and the long-haul segment was operated by American Airlines, we were disappointed but remained open-minded. Unfortunately, the overall service experience fell far short of expectations. This was a long-haul international flight. Getting up periodically to use the restroom or stretch is inevitable, especially on flights of this duration. However, each time we stood up, we felt as though we were inconveniencing the crew. The tone and body language often suggested that we were in the way or disrupting something simply by moving about the cabin. As a result, I avoided getting up as often as I needed to and was physically very sore upon arrival. Meal service was similarly impersonal. The options were presented in single words “beef or veggie,” “pasta or beef” without any description of what was actually being served. There was little engagement or courtesy beyond that. Even simple expressions of gratitude were often not acknowledged. I am accustomed to no-frills travel and do not expect luxury. What was disappointing was not the absence of extras, but the absence of basic warmth and professionalism. On a long-haul international flight, small moments of courtesy and humanity make a significant difference. In this case, the experience felt transactional and dismissive rather than welcoming. I hope this feedback is taken constructively, as there is a meaningful difference between efficient service and indifferent service.

Qantas is always subpar beyond comfy chairs for a domestic flight

an hour late, then had to disembark on back stairs and take 4 flights up to get to main airport. No warning, and difficulty for those with canes and poor knees.

Flight arrived late with no one to help over 30 people rebook. I slept at the airport.

newer aircraft, ability to connect my headset via blue tooth for entertainment.

Very comfortable flight, snacks and drinks were good, good communication from crew. Could have used a little more information on timing of boarding for group 5

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

It was better than excellent. The staff in Mason City were great. The young woman that pushed my wheelchair did more than could be expected of her. She came from India 17 years ago. I don't remember her name.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

The crew was generally professional. Though one of the crew members seemed to be easily annoyed, the others were fine and helpful. The green olives and almonds snack was really good. A great idea, and nice balance of tastes.

Every staff member was professional, friendly and courteous. The pizza twist was ok. It was warm but too much dough.

I had a terrible experience. My flight got delayed from Atlanta to Chicago on Monday April 6, 2026, and that led to me missing my next flight to Brussels. United Airlines didn’t provide me with any accommodation for shelter. I had to sleep at the airport in Chicago. The next flight I was put on didn’t leave until the evening hours of Tuesday 4/7/2026.

Food and drink service was very low quality. The flight attendants in business class must have been short some staff. Service was sluggish and not much English was spoken

The flight was officially delayed 3 times, and was actually later than that. Combined, it was a 3 hour delay, but there was no recognition (miles, voucher, etc). The crew seemed stressed. The captain sounded nervous in his announcements. The flight itself was smooth and uneventful.

After 3 hours of delays, they ended up cancelling my flight. And although I could purchase one-way tickets to get to my destination, they would not offer me these flights as compensation for the cancelled flight, and I didn't end up making it home until 13 hours after I was originally supposed to arrive. It made for an extremely strenuous end to an otherwise good trip.

Be careful about the bad policy and when purchasing seats

Very disappointed with premier lounge. Food selection very poor, both coffee machines out of order. For the price you charge for an upgrade, the seats don’t fully recline, movie selection is old. Not very good value. Asian airlines are light years ahead at a more affordable price.

The seat design in the premium economy section leaves virtually no room under the seat to store a bag or purse. Other than that, it was a great flight. Arrived early.

The flight was delayed, but not for weather. We landed over 3hrs later than planned.

The stag were helpful, kind and liked the passengers. The plane was pristinely clean! Great flight!

My flight was delayed more than once, but Air Canada updated us regularly. Friends on other airlines had much worse experiences.

My ticket did not exist when I got to the airport. I had to book another flight and was still charged by Kayak

Got denied my flight was told on Google that Air Canada was supposed to book me a flight back home because I never was able to go to my destination. They did not help me whatsoever. I had to book a whole new flight for that reason I would write this is zero

The plane was delayed an hour. Heard from other passengers that the Vancouver connection to SFO was never on-time.
