Pros: "The on board service was very pleasant. Enjoyed the movies on my seat's TV screen. Enjoyed the food very much!"
Cons: "First time on a 787 so was a little disappointed the economy class seating was still a little cramped, the in-flight entertainment and service made up for it though."

Cons: "The flights were everything I expected and more."

Pros: "Customer service was really good"
Cons: "The food always makes it hard to eat anything the next day."

Pros: "Incredibly nice staff made you forget about the older plane model you are in. Decent airplane meals and the nonstop from San Diego makes Japan now a frequent destination for us! I lucked out with 3 open adjacent seats roundtrip woo hoooo!"
Cons: "Movie selection was the same on return flight which was a bit of a bummer."

Cons: "I reserved Korean air but it was Japan air line. I was really difficult to web-check in to find my reservaiton."

Pros: "I was accompanying my 92 year old mkm, flight attendants were so helpful in every way."
Cons: "Pre-checking online needs improvement. I was unable to do it and speaking to JAL was difficult; no one was answering the phone."

Pros: "The flight's timing and airports are perfect for a short weekend getaway between Seoul and Tokyo. JAL service is also perfect!"
Cons: "nothing"

Cons: "They will not let me board the plane and I checked the airline before.leaving USA to make sure my ticket is valid and it's OK but when I was to return to USA on april10 they inform me my ticket invalid,cost me alot of money and inconvenience ,God bless"

Cons: "Not much leg room"

Pros: "Service from cabin attendants was excellent, specially the crew announcing up coming turbulence, foods, landing. Price is good as well."
Cons: "No big deal, I don't care some of the food, smells fishy. Like I said no big deal, still using Japan Airlines."

Pros: "The flight was great! Premium Economy on JAL is worth the price. The leg rest was a huge perk and luckily nobody was sitting next to me so it felt extra roomy!"
Cons: "The entertainment selection wasn't as robust as other flights. I had to make sure and "save" things for the flight back so I wasn't bored. I always pack a book or game along the way, so it really wasn't that much of an issue."

Pros: "Everything worked as planned."

Pros: "Efficient boarding process. Great god and cabin service. On time."
Cons: "Turbulent flight and the crew was not completely reassuring"

Pros: "Everything from start to finish was awesome. The "poor" review by someone complaining about a gluten-free meal is typical of Americans that feel entitled. You are on JAPAN airlines... you do realize the non-gluten-free rice is a staple of the country. It's akin to a Japanese person complaining that there aren't chopsticks provided with the meals on an American Airlines flight. How were the staff supposed to help you mid-air? Mid-flight dock so one special meal can be provided for you? How about this: take some personal responsibility and purchase your own gluten free food for the flight and carry it on. Really... how can one compare the 787 with individual on demand entertainment, roomy seats, full meal service (they'll even bring a meal to you if you were asleep during the normal service), etc... all for no extra charge?!?!? It is simply amazing what JAL (and every Japanese company) sets as a standard for customer service."

Pros: "Japan Airlines is very good. They have good service, safety, and customer care."
Cons: "Economy seats are a bit tight."

Pros: "JAL is the best airline I've ever flown."
Cons: "Food isn't to my liking but was good."

Cons: "My flight was cancelled from Narita to Hong Kong and they put me up in a small unclean room. I was very disappointed with their service."

Pros: "Good and polite crew"
Cons: "Business class cabin very mediocre for a state of the art latestBoeing plane"

Cons: "I hated everything about this 8 hour flight. Going to and coming from Toyko. The seats were EXTREMELY, EXTREMELY uncomfortable. I had to keep adjusting my body because my lower back was in so much pain. I ordered a kosher meal for both my sister and I but they only bought it for her. When I asked where was mine they said they didn’t see my name when I was the one who bought the tickets. It was extremely frustrating. I will never fly on this airline again."

Cons: "Food and entertainment could better"

Cons: "Economy seat was hard and uncomfortable. Meal tray is quite small. For international flights: Not ANA's responsibility, of course: the level of Hollywood movie artistry these days is so poor.
