Staff and crew are wonderful, professional and courteous. Meal is delicious and snacks can be improved. Entertainment needs improvement, pls update selections of movies. I appreciate that our flight was on time

I flew economy class so of course it’s not as roomy as business and first class. But overall it was ok and the seat had an interesting way to recline — the seat itself extended forward instead of the backrest. This way the person sitting behind me would not lose space by my reclining—excellent concept. I wish all airlines used these seats.

Flying with ANA is always a breeze. Seats are very comfortable.

The staff, ground and air, at ANA was very helpful and friendly during check in, boarding and during the flight. This is the reason why I always fly ANA whenever I go to Manila. The food was not the best but the flight crew more than makes up for the shortfall.

For the price of a seat that is obviously crammed together so as to get many more people onboard and combined with the long flight duration, Free WiFi should be an automatic “Thank You for Flying with Us!” To charge an additional fee when so many other businesses offers it is a bit “cheap” on the airline’s part.

It was very nice. I was a bit disappointed by the few meal services. There were probably more drink services that I missed while sleeping, but I would have liked the crew to bring more than one drink service before landing and to bring more than one drink service and coffee service after take off

Food was high quality. Crew was extremely professional, polite, attentive. Flights were on time. Plane had good media tech.

It was ok I thought because my flight was 1pm i was expecting to have lunch but it didn’t and after 7 hr finally dinner time was only chicken sandwich and next breakfast was an hour before plane land in Tokyo. so I should bring some food with me. Japanese flight attend was nice but the other was chewing gum and how she ask and respond to customers was not professional I felt. Maybe because Japan flight attendant is highly train and everyone looked very dress and professional so I was kind disappointed. I like that the bathroom was very clean .

Lovely airport at Haneda. Great food selection. Spacious and private boarding area with dedicated bathroom for each gate.

They did not get my request for veg food that i made a month ago. Also did not have any backup veg food on board or fruit plate or simething. Very disappointing as i had hward about how grwat ANA was supossed to be. Alsio entertainment was lacking and screen and tech was subpar. Overall just mid to low tie. They are living off reputation and are being passed up by most other carriers.

At least it was not very cold inside the plane. I noticed there was now a bidet in the bathroom and that’s good! I didn’t like the window seat. Flight was smooth except for 1 turbulence. Plane was on time. Thanks. Food was not that great. Miso and green tea were good! As usual movies were old and there were no changes.

More updated movies & Chinese movies. The food sometimes overcooked. Prefer to have more neat snacks in between than just choose from the menu. Please change the menu every now and then. This is my second time flying within one year and the menu didn’t change at all!

I didn’t like the check in process I had to check in at the counter took too much time . Didn’t give the upgrade my seat .

l enjoyed the variety of good and drink choices. The flight attendants were very quick and efficient to our needs.

Truly impressive service in the air. After the main meal, they have a delicious a la carte menu that you can order anytime until 1.5 hrs prior to landing. Flight crew were so pleasant and very efficient. Wish I could fly JAL more often!

Japan airlines is excellent. I had a great flight with them, and they are the consummate professionals. I booked my flight through Kayak and they sent it on to Underpricer. That felt really scammy. My Oneworld number would not attach to the reservation and I could not choose a seat. I called Japan Airlines and got one but it was in the back. Later I drove to the airport and worked with the excellent agents there to find a better one. Later that day, I got a phone call from Underpricer trying to upsell me the option of choosing a seat. It felt like a Spirit Airlines level crappy move. The flight itself was exactly as nice as you would expect from JAL. The meal was good and the flight crew was awesome.

This flight was operated by American Airlines. AA was completely unprepared for the crowds at DFW for Spring Break and were ridiculously understaffed. They had only three operating kiosks for self check-in, and ONE agent to handle hundreds (thousands?) of dropped off bags. She also had to do double duty to assist passengers at the kiosks. In comparison, flying on United Airlines at Christmastime was a much smoother experience.

Need new movies, a lots of them are 20-10 years old or older. It us a very long flight we need good entertainment. Please load more new movies!

It was one of the best experiences. The staff were amazing. JAL is my second favorite Asian Carrier I have flown on. Korean Air was my first. Thank you JAL for bringing me home safely and for such an amazing staff and service.

JAL is quite nice in business class. Comfortable, spacious seats. Their entertainment, especially their film selection, isn’t that great though as their are not many new releases like some airlines offer their first and business class customers. . Food is excellent and the option to order on demand is always quite nice, which JAL offers. Flight attendants were very friendly and kind. Overall very good experience with JAL.

I am going to be just factual, not bad mouthing nor complaining, but this was my experience. With 3 pieces of luggage, I was told the flight from Mumbai to Dubai was cancelled due to flood. This was told not by the airport board which still showed the regular time of departure, but general stuff at the airport. No Emirates stuff around to direct the transfer passengers of the cancelled flights. By the departure counters with crowds of people, one by one, angry, frustrated, urgent conversations were going on. No announcement were made, no postings being seen, just private conversations. I still have 5+ hours of layover, so I let more urgent people settled first. However, the fact that no communication of when, what and where I should go was very unsettling. Basically no time limit waiting means, no meal, no sleep, no step away, no planning, no change plan, no telling of the family what to do. Nobody was able to tell you anything but asked you to wait, no chair, no space, no facility to freshen up. That went on for 10+ (from 5) hour without warnings and accurate communications. Email received from Emirates asked me not to go to Dubai at all, or boarding at the time that was passed. In other words, communication were very untimely, after the fact. That created more confusion instead. After changing several of boarding time, we were given the gate # and a boarding pass. However, the boarding pass still have the original time of boarding, so again, not knowing walking 30 min in the airport to the gate would make you late or not, therefore, still dare not to eat a meal. The flight arriving to Dubai was uneventful and I gave a 4/5 rating. I just thought the layover at Dubai would just cut short from 8+ hours to 2+ hours. At Dubai airport, I saw people sleeping on cardboard, knowing, these people got stranded but they dared to sleep because they know when to board and I didn't. Or these kind of delay are just so normal that people know what to do to pass time. Then the worst service and crazy thing happened. The boarding time on board for LA and at gate A9 was clearly 8:50AM. At 8:40, surprised by not having any boarding activities, then one single staff showed up and said to a few passengers that the boarding would be delayed without a time frame. Since only a few people know, I asked another Emirates staff at another counter, who simply said basically non of his business. I was shocked with that indifferent attitude. Yet every boards I saw show the same boarding time. What kind of system failure was that to prepare delay situation! How confusing and unnecessary chaos and anger that provoke. That poor staff had to repeat himself so many times, answered questions that he had no power nor information to provide nor solved. One an only one stuff to show up for 10 min, leaving the counter non-staff with board showing 8:50AM boarding. This was purely irresponsible from top to bottom of the entire airline operation staff. What kind of leader in a service industry would allow this to happen to their customers. Without explanation, after changing 3 times the boarding times, again, means you should not go to eat a full meal, because, when you found a mob at the gate. People who were stranded for 2 days were afraid of not getting a seat with a full plane. That would not be happening if the airline provide adequate guidance to each person, instead of just having 4 staff yelling at the gate at the same time to "control" the crowd, threatening no boarding and delay boarding. Finally, I was on board, hungry and tired, not sleep for 36 hours. I was denied with a snack of fruit. By the time meal was served, it was an hour later. Half way of the trip, I felt sleep in fetus position and did not want to move, happy I finally could have some shut eyes time. However, when I got up to the bathroom, I felt very light headed. Having sleep deprived, constipated for 3 days, dehydrated, I knew it could happen since my blood pressure usually was low closed to 90/60. Any lower then that, I could have syncope. Sure enough, I was on the floor just 10 feet from my seat and 5 feet to the bathroom. However, nobody called for help. I asked for warm water and juice to hydrate, came only with cold and icy drinks which I wouldn't take. I asked for blankets, one was given. Yet my shivering, needs to cover my head and multiple requests did not hasten to take the two blankets that are at my seat 10 feet away. I waited 10 min for that. While 2-3 staff surrounded me, nobody did the vitals until after 15 min, just the spirometer only of which did not work due to my cold fingers. The first reading was 86 and oxygen was suggested. But another supervising personnel came, fussed over another reading, ignoring my comfort and needs. Seemingly the reading of spirometer was the priority. By then, no oxygen needed. I had this fainting experience before, and I knew how to help myself. However, I was not being listened to but to be told this and that. Finally, I got better and returned to seat. One kind flight attendant said she would check back with me in 15 min. She did not come back. I felt asleep in that fetus position again and this time I woke up with a bad cramp at my left leg. Yet I needed to go to bathroom, the cramp was too bad to walk. So I stepped back to seat. When I tried again the second time, the other front leg got cramp. This time I dare not move but massaged myself. For all these 5-10 min, I called for attention. Attendants passed me by because they were carried with heavy load of blankets and stuff. Nobody answered the light. Then came landing and off board. I was asked by two attendants how I felt. I smiled and said "fine".

The customer service was very poor. I didn’t get any accommodations for my cancelled flight. I was without any sleep for 36 hours.

The customers before boarding the plane from Dubai was HORRENDOUS. The entire Emirates staff had a stick up their bum. The guy at the check in booth was rude. I don’t understand.

Food is really bad, not to the Emirates standards. Coming out of Houston airport is very confusing,

Service needs to improve. Air hostess do not register flyers request and we need to keep on repeating our request to them on multiple occasions

The flight was great. We had to purchase extra long seats for the long flight. But overall it was great.

The experience was not as pleasant returning as leaving. Went through clearance twice, crew was not as customer focused.

WORST AIRLINE EVER—FOOD WAS MEDIOCRE AND WIDEBODY 777 BOEING WAS VERY UNCOMFORTABLE! IT WAS NOT WORTH THE MONEY THAT I PAID.

Amazing service and food. However I didn’t get chance to choose my own seat which bothered me a little.

More space all around is practically essential on long international fights, and Emirates definitely delivers. But food selection and taste was only average. Otherwise, the flight was smooth and the cabin crew service was fine.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

One of the best flying experiences I’ve ever had.

The flight cancellation and process for getting a new flight was not that clear. United also had some delays that were unexpected. I am the most disappointed by the fact that I originally bought a Lufthansa ticket, only to be flown by United.

Need to have more snacks for the duration and coffee.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

On time - really well operated flight. Friendly staff. Super impressed with United on this round trip.

It was ok until we got to DC and I wanted to use my United Club pass and the snobbish receptionist said that they don’t take one pass. It took me everything itch of patience not to tell her off

Food choice was poor and we had to buy on board snacks.

We were offer chocolate cookies , not everyone eat chocolate. Thank you

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.

Not enough trash pickups throughout the flight. Everything else was great.

Overall good, the gluten free food is very hit/miss though and you must tell them you have an allergy days in advance.
