Pros: "Amazing crew"
Cons: "Perfect"

Cons: "The flight was fantastic. It was a long flight but the flight attendants took excellent care to keep us comfortable."

Pros: "The crew was super friendly."

Pros: "The Crew was great with kids, and went out of their way to reach out to the boy sitting in the row in front of me."
Cons: "I was running late, and lady that checked me in was accommodating but a little bit standoffish."

Pros: "The food and legroom"
Cons: "More movies :)"

Pros: "I did upgrade to economy premium which is why the flight was very comfortable. Would not have upgraded except I made a mistake in the currency conversion and thought the upgrade was cheaper than it was."
Cons: "Did not really like the chef's cuisine as opposed to the one on my outward flight to Japan which was excellent."

Pros: "Crew was courteous. Flight in general was uneventful which is a good thing."
Cons: "Nothing to criticize. Flight experience was good but not exordinary."

Pros: "Sky Time drink was interesting. Flight was on time."
Cons: "More leg room. Better information on what is included as far as meals / drinks."

Pros: "Pretty much everything"
Cons: "Nothing"

Cons: "Please contact me immediately!"

Pros: "Seats, movies, comfort"
Cons: "No vegetarian options"

Pros: "I wish all long haul flights were like this. Very clean and well maintained cabin space, good quality food, very attentive, helpful and polite cabin crew. Never thought I’d be able to say this, but the 14 hour flight with two young children in economy was a really enjoyable experience with JAL!"
Cons: "Really no complaints"

Pros: "even though middle seat, there was enough leg room to rest comfortably."

Pros: "The crew"
Cons: "Being late"

Pros: "none"
Cons: "very poor communication of information"

Cons: "Tight seating."

Pros: "Was fed a meal and snacks/drinks for this connecting 3 hour flight in economy. Hard to sleep in the economy seats, But with a blanket and thick clothes it would be better! Japan Airlines crew extremely nice!"

Pros: "The flight attendants were very attentive and polite, seats are some of the most comfortable of any airline I've flown (particularly compared to the US domestics), entertainment is solid (although the English movie selection was not that large), and we were regularly offered food and drink if we were awake. I would definitely recommend JAL to others."
Cons: "The food was not to my liking (i.e., all Japanese style, but not necessarily types that appeal more to Westerners) but it was palatable."

Pros: "Friendly and attentive staff with excellent amenities ie: check in, seat space, food quality, movies to watch, music, ...etc."
Cons: "Nothing to complain about here. Both trips to Tokyo, Japan--to and from Japan have been enjoyable and drama free."

Pros: "The staff are always very polite and professional. Food was fine (better the past years). Everything was punctual and orderly."
Cons: "The seats were extremely uncomfortable. The gray ones were much better (San Diego to Narita) in comparison."

Pros: "good flight"
Cons: "food is ok"

Pros: "The staff are very friendly and accommodating. The food is superb. It doesn't seem like we had a long flight because of the great service."
Cons: "None"

Pros: "Excelent good service.Staff are friendly."
Cons: "Almost i like everything"

Pros: "Amazing service and amazing food! For such a long flight I was extremely comfortable! Loved that the crew members kept me informed since I was spotty with Japanese they were very good!"
Cons: "Can't really say anything bad! It was great!"

Cons: "I wasn't able to pre-select my seat."

Pros: "Plane is modern with good in flight entertainment and a usb charger to keep your mobile devices charged."
Cons: "Because it is Japan Airlines, the food is authentically Japanese. Unlike US based international flights, they only serve one meal with zero alternatives."

Pros: "I like the food best.."
Cons: "Hope there will be more tracks from arashi."

Pros: "Entertainment options were good"
Cons: "Food was mediocre and long waits for restroom"

Pros: "JAL always have good services."

Pros: "Wonderful Crew."

Pros: "When I checked in for my flight it was fast, efficient and friendly. Their Manila staff is awesome! I was very impressed and happy with their service. I will be using JAL again."

Pros: "everything, the courtesy of the entire crew, the way they show care and respect and compassion to the passengers especially the seniors"
Cons: "flight delays"

Pros: "My sister got airsick the last hour of the flight. The flight attendants were extremely helpful and considerate in easing her discomfort."

Pros: "Great service, attitude, hospitality. Was never treated this nice on any flight ever. Thought I was a king or prince. And that's how they make you feel. If I can, I only fly JAL and especially the flight JL9"
Cons: "The fact there are many airlines which can't even get close to what JAL can offer and even if they try, employees won't be able to match it because of the cultural differences. Makes me sad that other airlines (I won't name them) can still be in business... they need to fly JL9 once and hope they understand."

Pros: "Everyone on the flight was very nice and helpful. Food was excellent! There were a lot of choices of movies to watch. It was probably the best flight experience I've ever had and I travel overseas quite a lot. If I ever get the chance to fly them again, I will. Great service and outstanding experience."

Pros: "When I checked in for my connecting flight from Tokyo Narita to New York, the crew said there was no more seat on economy class. She was making sure that I got on the plane by placing me on the premium economy seat. I appreciate the effort and the courtesy of JAL."
Cons: "The meal and dessert were served at the same time. Too much food all at once."

Pros: "The cabin crew was professional, friendly and courteous. It's always refreshing to fly an Asian airline for the impeccable customer service. The 787 left me with minimal jet lag. The odd shaped pillows provided great back support."
Cons: "The seats were comfortable but old fashioned. The WiFi was spotty and it would have been nice to have Asian food options."

Pros: "Good in flight entertainment options. Great food and plenty of it. Service was top notch. No complaints."

Cons: "No individual AC vents to stay cool on long flight."

Pros: "Nothing"
Cons: "Flight was diverted to another airport and when we finally got to Tokyo, the next flight's gate had closed even though it didn't leave for another two hours. We had to wait in a huge line to get rebooked and it was clear the Japan Airlines employees did not know what they were doing. Put me on a flight next day and couldn't even provide hotels for us (gave us $100 to find our own which was near impossible at that time). I had to sleep in a sleeping bag in the airport overnight by myself."

Pros: "Our flight had a long delay, but one we were on board it was a short and smooth flight."

Cons: "Boarding was actually good. It was checking your luggages in and getting your boarding passes which was POOR. Passengers on International flights going out of the Philippines are advised be at the airport at least 3 hours before scheduled flight. Well, the JAL check-in counter opened at 650AM for the 950AM flight (exactly 3 hours before the scheduled flight), with maybe some 50 people already in line. With most passengers coming far from the airport, it will be very very helpful if the counter, even at least one counter, would open earlier, so that passengers who came in early could check in early and wait comfortably in the departure area."

Pros: "Service was wonderful! Domo arigato gozaimasu. Aloha, Cary"

Pros: "Excellent service"
Cons: "Not a lot of vegetarian options"

Pros: "The ground crew in HKG airport was really helpful."
Cons: "I have been flying JAL from HK to Boston numerous times and by far my favourite (over Cathay and don't even need to mention United). However this past trip gave me a new perspective. Given it is a Japanese airline and all, it is normal for them to be Japanese-centric. We had an a-hole sitting in front of us at 51F during our flight to Narita and he was trying hard to argue with us in English, and even told us to move to another seat. When I had the flight attendant (her name is Sako on flight JL736 on Jul 26) over to discuss (in English) she went to the guy in front of us and started apologizing to him. For what??? She then came back to us speaking in Japanese and brushed the issue away. Sorry, no this was not acceptable, even though my fiance was okay with the situation."

Pros: "Cathay and JAL Provided excellent customer service throughout the the flight. Everyone did an excellent job and went out of their way to make sure I made flights and had what I needed."

Pros: "It was my first time flying to Japan from LA and the experience was great. Yeah my flight was delay by 3 hours for reasons out of their control and I missed my connecting flight but they completely made up for it. The food and drinks were really good along with the service. Plus they booked me on another flight along with a hotel for the night. Awesome service and experience, I would travel with them again."
Cons: "I don't have anything to complain about."

Pros: "JAL in general."
Cons: "NA"

Pros: "Food is great. Crew are very friendly"
Cons: "The touchdown, it's not smooth"
