JAL using the state of art A350-1000 for JFK to HND It’s a great plane to fly Very comfortable with lower cabin altitude Quieter cabin Wider seats Big tv screen Excellent service and catering

The flight attendants were excellent as usual however the meal wasn’t the usual good quality. There is cooked rice was mushy.

I fly to Asia twice a year for the last 15 years. I always try to fly JAL. It’s always a pleasant experience. Since TripCase shut down, this is the first time I used Kayak for live trip notifications. I was very pleased with Kayak’s quality and helpfulness of notifications. I will be using them going forward.

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.

Allow gold card holders (Group 1) to board with their guest like other One World carriers do

Checked baggage process is confusing and time consuming especially when checking oversized bags. Very slow agents didn't help.

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.

Could had been better if they include in their menu some western food.

They 7 seats in one row for Business class while most business class for other airlines are 4 seats in one row. the seat was narrow. the Toilet was so smell, dimming light, no water out of faucet. Terrible.

China Southern was not the problem. I booked my flight through Kayak and also received a booking reference and alert details regarding departure time and gate numbers… however Kayak NEVER actually booked my flight! We were stranded at the airport without a flight for a long awaited holiday!

The connection between LA and Atlanta was too much stress

Terrible boarding experience,,food is very poor that I I . Never going book this airline again.

The crew were kind, patient and responsive. The service was excellent, even though we travelled the cheapest economy class. We arrived at our destination 40 min early, which for a 15+ hour flight is a great bonus. The boarding seemed a bit "loose", but got us boarded on time, and the plane was off exactly @ 0:30 hrs.

The airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.

The flight was delayed hours and most flights from CS are always delayed. Plane was efficient and got us home but not the best food and no entertainment system at all.

Not good - chair back could not move back for premium economy. Not worth the price

The back of the chair - premium economy could not move back - not worth the price

It was okay. Boarding the staff made you feel rushed like we were late or something

It was great. The staff were so nice and helpful the food was great and they always made sure I was okay. As a foreigner I was worried about the language barrier but it was absolutely no issues. I highly recommend

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Food & service very good next I will pick up again

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.

I wish I had been able to choose a vegetarian meal. Crew friendly and helpful. Seat was ok. All quite efficient and pleasant. Would recommend for inner China travel for sure.

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

It was simply bad and on top of that my luggage hasn't been delivered until now. They can't even localize it which is just unacceptable when they are supposed to scan the bar code they put when we check in

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !
