Very poor experience and will never travel with JAL again. With Business class ticket i was told that there is no veg option for the 1st leg of my journey from Delhi to Tokyo while served horrible plant based meat on the second leg of journey even though i selected Vegetarian meals. Also entertainment system is worse than domestic flight with hardly any Hollywood movies and no hindi movies at all

Also entertainment system is worse than domestic flight with hardly any Hollywood movies and no hindi movies at all

Staff were friendly and awesome! Some Filipinos are just undisciplined, but not an airline problem.

Good. The only thing is that I missed the flight.

Food we select all the airlines, but they said not selected, it’s bad experience.

My seat was so hard and uncomfortable. I took AA to Japan longer flight no tailbone pain. Coming back on JA shorter flight my tailbone was killing me no cushion on seat or just worn out.

Not very much of anything, it probably was once of my least favore business class flights I have experience in all the times that I flew Boz class

I always enjoy flying with Japanese Airlines. The whole experience is always a pleasure. This flight was no exception. Thank you Kayak for making it so easy to decide.

Very smooth onboarding and offboarding. Food provided was cold and not the best.

Terrible experience. Staff would not even refill my tea once. While they refilled a fellow Japanese persons wine 7 times. They also lost my luggage. Horrible. Go elsewhere

main courses of the primary meal were not good- the beef dish was really not good-

Boarding was good and efficient, however since this was a late flight I spent most of the time sleeping so can't express any further opinions

Not at all satisfactory. I had stomach upsets after taking food. Quality of Asian vegetarian meal was awful. Further there was no snacks/ fruits/ biscuits available as in between snacks.. only peanuts and pitzels.. except courteous staff rest of my experience was far from satisfactory

See previous answers. Also food options limited, entertainment difficult to use and did not work properly, lay flat bed is quite big but very hard and uncomfortable

one hour transit not good. cathay pacific is not helpful at all

Well- trained, cheerful onboard staff. Business class seating and storage were excellent. Outstanding range of food choices, though quality ranged from just OK (seasonal rice and beef dish) to outstanding ( congee and soup noodles with beef brisket). But what can you expect; it's on a plane. I couldn't figure out the remote control, but touch screen worked well. My wife and I (in our 60s), didnt find much to watch from the Entertainment choices. We mostly watched the flight maps. The bedding did the job but is unwieldy and ends up in a clump, with one-third falling on the floor.

Boarding at the airport was not well managed. Otherwise, had a good flight sitting in the first row (which I paid for). Crew was pretty friendly, and flight was smooth.

Cathay was not the problem. The problem was the customer service from Kayak/Underprice. Will never book through Kayak again.

There is very little in the title" Premium" in the Economy experience with Cathay, Melbourne to Hong Kong. The seats are uncomfortable and the cabin with outdated 1990's decor and trim. The food service was sloppy and the leg room providing little to no advantage over regular economy seating. Infact, the Sunday flight was not fill occupancy and I would have done better saving the significant additional costs for the PREMIUM ticket and taken advantage of the seating. If you are a regular premium economy traveler of EMIRATES expecting the same experience on CATHAY, you will be disappointed. Emirates far superior.

The overall flight went well and the aircrew was pleasant.

Would have liked working outlets on the flight. The first meal was very bleh, the second meal was a lot better so overall okay meals

It we as a pleasant flight. Good helpful and happy cabin crew. Food was okay, not to write home about. Drinks good. Entertainment okay.. Seat space good , comfort acceptable

The meals were not the greatest and lacking of appetite but everything else was spot on

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

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 !

China Eastern as a member of Sky Alliance airlines should have the same standards overall of their partners, Besides the seats comforts everything else is bellow the standard for a business class travelers.

Excellent experience however older aeroplanes used by China Eastern Airlines.

The crew were excellent, service amazing, blankets and pillow good, cabin temperature perfect, the flight on time, food was unusual selection however plentiful, price for tickets unbeatable through Kayak. Older aeroplanes used by China Eastern was the only down side.

Reasonable. What they offer during the flight is not great, but the crew is polite and try to compensate it.

Lost Baggage - very frustrated…learned that bag was never put on plane.

I think it’s time that somebody set a standard for the temperature in the cabins. I would rather it be colder than anybody that wants to have a blanket have a blanket to keep it so warm at times is unbearable and quite uncomfortable. That’s the only thing I would add.

Good airline for the price. The Air stewardess are great, nothing is to much trouble. Will use again.

The landings were smooth . Being unable to check-in online was terribly stressful and the queue at Haneda exemely long. We paid extra for window seats and did not get them.

I will never fly through China again. Maybe it was the mandatory retinal scan just to transfer to another flight or the complete set of fingerprints they require. There are many better and inexpensive flights to Asia if you look.

A lot of value considering the cheap ticket prices. All meals served were Chinese food. Would fly them again considering the ticket was half the price of any others

Check in desks at Bodrum we’re not labelled properly to the point we ended up queuing at the desk only for the signs for business and economy to be put up later and we had to move lines to go into the economy queue. By the time we got to the front, we ended up be ushered to the business queue anyway to get checked in. The flight left on time but then we had to circle the air for a good 15 mins and then when we landed we had to wait to be taxied for another hour. Our baggage didn’t arrive but nobodies did but were told after an hour of waiting that no more bags would be delivered to all passengers had to fill out a form to get their bags delivered. Could have told us that a while ago. Very poor communications

Boarding was seamless, crew were great. Less disruptions on the night flight would have improved the experience and turning off lights earlier.

Worst customer service I've ever experienced on a flight. They downgraded my seat without giving me any other options, then sat in a seat with an arched back for 10 hours. I was not able to get ahold of any customer service representatives to understand what alternatives I might have, or how they will be handling a refund for the difference in fares between business and premium economy that I was downgraded to.

British airways needs to improve their luggage handling process and communications. The luggage was lost/left in UK. But, this was not communicated to me as a traveler and because of the wait at the carousel in Seattle (we have to go through customs and immigration on arrival to US) I missed the connecting flight and had to be rebooked. No one informed me that the luggage wasn't there, and there was no one there at the carousel to check with or help me get through security faster. I wasn't the only one- there were a lot of people waiting for luggage that didn't arrive.

My bags were lost. I waited in a line for 5 hours after I landed and got no resolution to the issue.

Easily one of the best flights I’ve ever taken. Worth it to upgrade slightly. Crew was phenomenal. Just wish the man sat next to me kept his shoes on. There should be a rule about that. But I wish I could take every flight with BA.

Poor experience at Bengaluru Airport. Slow check-in process. Boarding calls were unclear and by number (no clarification given for priority groups) and were caught in wrong queue with infant based on what was written on ticket. Aircraft seat was not comfortable. Slow initial service for flight at 03:00 where most passengers wanted to sleep - did not seem right to be serving meal after takeoff. Poor quality breakfast in morning, not offered any tea/coffee alongside Only saving grace was that this was a night flight and the plane had free high-speed Starlink wifi.

Great flight, great crew, decent food. Premium Economy was very comfortable. I compare this flight to the one we took on BA from DC to London: Like a different airline. The food was atrocious, the crew aloof, and the cabin not as comfortable. Based on that first flight we said we'd avoid BA, but the return trip changed our minds.

delayed more than an hour with very poor boarding and service

A/C temp. was way too cold during the flight.
