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.

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!

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.

I was so hungry , from Boston to Tokyo, only 2 big food .

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.

Other than needing a bit more content on the IFE, Japan Air Premium Economy is amazing! It includes lounge access, and other than not having lay flat seats, felt better than some business cabins I’ve been on.

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.

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

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

I’ve always had pleasant experiences with ANA and that has made me a loyal customer.

Good flight — left on time due to on time arrival of Pittsburgh flight

Delta keep on impressing me. Right now Delta airline is the best of them all

Good but since we got in early we had to wait on runway for our gate. That was kind of a bummer but we still got in earlier than planned For entertainment I was watching a movie and getting close to the end of it with 15 min left but it kept jumping automatically to the next movie before finishing.

13 hour delay stuck in Detroit and missed a day of meetings. It was terrible

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

The cabin was definitely dated, but that's about par for the course. The flight crew were wonderful as always (always a Delta highlight), but the boarding process was slow with little direction or encouragement to get people in their seats quickly since we were already delayed.

Totally organized, quick boarding, professional staff and ON TIME! Good size seats in the cabin Wonderful experience

The flight was delayed to board, then delay in landing and extremely bumpy landing.

Could have been on time and not missed my connection

Flight Staff: Always great! Checking back vs carry-on: I typically check my bag since so much time is spent stowing the bag, it's heavy, maybe not enough room. Delta is charging $45 to check bags. Yet, the people who have multiple carry-on bags are then asked to check their bags and are offered this service for free. This does not seem fair to a person who is trying to be proactive in improving the process . Boarding: Boarding is always slow and exhausting. With the exception of First Class, Economy, why not board the zone in the back of the plane first??? Seats: Why cross the seat belts? I get that it looks nice, but people waste so much time moving them or sitting on them and then having to move. Seats: On both my flights the seat did not recline. Not a big deal. Smell: There was a horrific smell like the restrooms on my first flight. I thought I was going to be sick. Most flights do not smell great. Does Delta use air purifiers or anything?

⭐ Absolutely AWFUL Experience with United Airlines! If I could give United Airlines ZERO stars, I would. The seats have practically NO legroom, making the flight feel like being crammed into a tin can with nowhere to move. Comfort? Forget about it! And the fees? Absolutely ridiculous! They seem to charge you for EVERYTHING. You pay for your ticket, then get hit with extra charges for things that should be part of a decent flying experience. What’s next, charging passengers for breathing? Flying with United feels less like being a valued customer and more like being a walking wallet. The seats are uncomfortable, the legroom is pathetic, and the constant nickel-and-diming is infuriating. For the price you pay, you would think they could at least provide a little space to stretch your legs and a travel experience that doesn’t leave you feeling ripped off. Do yourself a favor and look at other airlines before booking with United. I certainly won’t be rushing to fly with them again. Absolutely disappointing from start to finish!

Flight was very smooth from Boston. But when we got to Houston, the gate was not open and we waited on the runway for over 30 min!!

My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.

Horrible on the chicago end. They change hates then there is a plane at the new gate so we can’t pull in. Then that plane has mechanical issue and needs to be pulled back to the gate but we can’t get to another new gate due the other plane being in the way. Horrible gate management which will cause many customers to miss connections.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

Great, except the canon was so cold. Even the flight attendants put jackets on

The app logs you out right when you are boarding requiring all passwords and reservation number for the flight. Super annoying

The pre-order only approach for fresh food is really challenging

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

Liked they had tv screens on plane but no service for drinks and a snack when other airlines do

The plane was very cramped and no room to move. Other passengers brought suitcases that didn't fit in the overhead bins. This made boarding and departing extremely slow.

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

everything was fine. but paying for 1 piece of check-in luggage and denying passengers to board with carry-on luggage which by air line's standards does not fit is not acceptable. when one travels for a longer time one needs to have some essentials

Pearson Airport could not properly handle all the passengers who they needed to process in order to properly get them on board. As a result, I missed the departure of my flight from Toronto. The only saving grace is that Air Canada found a flight that only delayed me by one hour. However, this was no thanks to Pearson Airport!

I had a good experience. I liked being informed about the status of my luggage

The staff could have been friendlier. And Having the flight on time would have been much more convenient.

Old, noisy plane, bad coffee, delayed. Flight attendant was very nice.

We boarded 1.5 hours late. Long wait for the bags when we got to Mexico City. Long wait to get on plane with people mover truck. Friendly staff. They answered all questions as best the could. Such a long, long walk from the plane to customs. Thank you, Michael A. Burris Cambridge, Massachusetts USA

I was forced to check my carry-on bag, which I don't appreciate.
