Not many people, so you can lay down on two seats

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

long flights are difficult but the crew and amenities made it a very good experience

Our seat row plus one ahead and behind we're completely overlooked during beverage service...

I loved everything, I was just a little confused on my bag allowance. When I checked in it said I was allowed 2 check in bags, but when I got there they said I was only allowed 1 so I had to pay an additional 200 dollars! Other then that everything was great! I would love to use your Airlines again when I fly out to Manila again in late May, however I want to be able to have 2 bags included this time lol 😆

Need to have space for Cary on when traveler boarding any zone

When I selected my seats, it showed row 29 as the front row, so I paid extra to sit in what I thought would be the front row, but when I boarded the plane, row 29 was the second economy row. I was disappointed that I'd spent almost $100 more for no actual benefit.

This portion of the trip from HCMC to Dallas was operated by American Airline. Unfortunately they are 2 steps below JAL in overall quality. Regardless, AAStill got me where I needed to go on time.

First experience with JAL so was okay to pretty good. 10 hour flight in premium select seat. . Seats in that category should be better than pretty good. Seat pan a little short for tall people but plenty of leg room; I think JAL in process of new planes? Also, — they could have offered a bit more water throughout flight and meals not the greatest. That said, certainly 200 percent better than a very recent AK Air International flight in similar cabin class in comfort and meals.

We ordered for non vegetarian Hindu meal but instead they served us vegetarian Hindu meal. That was also not good. It was very annoying and aggravating. Hope our return from Tokyo to jfk on March 27 same is not repeated. Caterar should understand difference between non vegetarian Hindu meal and vegetarian Hindu meal.

Food was great, Entertainment was bad, movies were not current and just did not have good variety. Granted I was tired so cranky might have played into my evaluation. Overall based on cost I definitely would fly them again. I am a million mile flyer on another airline, the service on JAL really beats all airlines.

Was in premium economy. It is slightly better than economy, but the way the seat reclines actually makes it harder to sit (the seat slides forward and the foot rest comes up - you can lie fairly well reclined but you’ll have to sit cross legged because there is no place for your legs to stretch out. Food is basic economy. Service was great. All in all good, but may make more sense to pay more for business or save a bit and just sit in economy.

Seats in "Premium Economy" were noticeably more comfortable than those in "Economy" and worth the price. My only reservation is that the foot rest did not go higher up. If it did, it would have made the seat much more comfortable.

Attentiveness by crew was very good. The seats were uncomfortable seemingly too hard with inefficient cushioning. This was verified with my traveling companions. Also the incline button was inoperable.

I purchased the ticket online and went to do online check in amd the app wouldnt let me. I went to the airline desk and they couldnt confirm my ticket in their system. I ended up having to buy a ticket from the airline directly and paying twice for the same flight. The app wouldnt lwt me check in the kayak purchased ticket until after my flight was taken off.

A great flight experience - great seats, lots of ROOM for legs & in the aisle. Great attendants! My flight cost me the same as ZipAir, the website was WAY less confusing & wonky - this will be my 1st choice for my next Japan trip. Very pleased / well cared for.

The plane was dirty, there was trash in the seat pocket in front of me.

My wife and I liked everything except the cold breakfast

Excellent service and comfortable seats. Friendly and helpful staff. No food for a 3hr flight over lunch time which was surprising (or is that a feature of domestic flights in Japan?)

When booking the flight i picked it because it said flying with ana even on our e-ticket as well but I showed up to the airport and I flew with united. I have flew with both airlines before and I prefer ana for the food quality and comfortable. So I was disappointed in that outcome and felt the food gave me minor ibs. The whole thing was missing leading with not getting what I thought I was paying for. Felt a bait and switched. Do not have confidence in using this app in the future trips

This was a large plane with an upper deck. It seems like business was upstairs. If it was a US airline then I would say I sat in economy plus, but I think it was just economy. Though since ANA would not allow me to choose seats for the price it may have been plus. Lots of movies to choose from, and good service.

This was the best airline I’ve ever taken. The staff are amazing. The food was great. The pilot was phenomenal. I would highly recommend this airline.

There wasn't much entertainment for my short flight but the onboarding process was smooth and the crew provided wonderful service. The seats were also reasonably comfy. Great flight.

I had to get rerouted because the weather delayed my flight enough to miss both of my connecting flights. I select nearly 2 hours on customer service trying to get rerouted and had to miss my first plane which took my luggage to San Francisco. Luckily, customer service sent me to the same airport but I had to ride 12 hours in economy after I paid extra for premium economy. Totally sucks that I overpaid. Customer service and airplane crew were great and really helpful though. Although I still hate how small the seat was, especially since I'm smaller than average, I can't imagine how much it would suck for an average sized person.

Cabin crew were excellent in taking care of my mom as she boarded the aircraft from her wheelchair. Did not care much for the food served.

I stopped flying with United back in the nineties. Today's experience reminded me of why.

Wonderfully pleasant experience. Good meal and beverage selections. Professional air staff.

Delta flight was on time, seats were comfortable, and crew was nice.

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

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. 👍👍

The gate was too far away for the connecting flight

Compared with other carriers business class for an overnight was not worth the extra expense.

Seats were comfortable. It’s was so cold and very uncomfortable. I paid 2000 miles for wifi service that was choppy the whole flight. Would like to be reimbursed for my miles Food was so disappointing. Three cold and terrible meals for $3000 round trip. This needs to be better.

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

Smooth flight. As always dinner could have been more generous. Breakfast was great.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

Old and out of date plane, it seem like every time I fly with united there’s and issue. We were delayed,
