The crew was great. There was no wifi The cabin temperature got very hot Seat was uncomfortable
6.0 GoodAnonymous, Oct 2026
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!
Stingy on the drinks - 15 hour direct flight and could barely get attention for some water
not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(
Always fly with Korean Airlines. Best service great food. Nice and clean as always.
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!
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.
Boarding was delayed by an hour and then we proceeded to sit on the tarmac for another 30-40 minutes. No clear explanation was ever given and the delay caused me to miss my connecting flight home. Was forced to stay the night in the connecting city which impacted my following workday and cause personal issues at home as well.
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
Great flight. I should have figured out the bed situation in biz class earlier. Confusing in dark. My bad.
Business class check-in was flawless; was automatically given a lounge voucher. Flight attendants were helpful and professional. There was a purser who introduced herself at the beginning of the flight but then I never saw her again.
For a 17hr economy flight it wasn’t bad at all, thankfully it wasn’t a narrow body plane.
Simplicity of boarding and corporate interactions were all totally positive and simple, brief, organized and clear. No regrets at all. I will favor flights with Cathay Pacific in the future.
Big selection and great food and beverages in business class with good service. Full recline but less privacy compared with Qatar.
Really impressed with the Airline and much with the Crew. The crew was amazingggg, changed seats very easily, provided a lot of snacks on demand, the plane is nice and clean, the menu is well presented; unfortunately, the food is not fantastic, but it's not bad either but nothing to rave about. I am still rating it as excellent because I loved everything else; food improvement will be great!
My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.
Seats in the absolute back row of the plane even though we booked ages ago :( Crew was awesome though
From BOS to HK, the crew had pushed me to choose the pasta for meal multiple times. It was a bad experience. Without this, everything was good.
The overall flight went well and the aircrew was pleasant.
⭐ 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.
