Overall, very uneventful and pleasant experience. Most importantly, no delays.

Not very comfortable seated in the back plane due to turbulence

Everything about Korean air is great, hands down! Will always prefer this airline from other carriers.

I enjoyed flying on Korean Air. The service was great and the food was yummy. They served white fish.

Ford not that great the seat not to big for leg room like other airline

Great crew, decent food Charging plugs were broken on both seats next to me. Only the USB port was available, and that charges, very, very slowly. Seat was also broken, it would not lock into position when reclining.

It was ok. Not good and not a bad experience

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

Stewardess are nice. Food could have been better and should have a better dessert. They do not offer scotch or beer. You have to ask for it. I also was not happy that you do not serve ginger ale and or cranberry juice. This is my first time that an international flight do not have this. I go home overseas every year and when I travel through ANA, Delta, Qatar, JAL, Asiana Air, United Air. they all serve this two very famous drink. You do not have a great snack tray.

All of the JAL flights in this itinerary were great. However the last leg of my flight from LAX to SFO was through Japan Air’s partner, AA which wqsn’t up to par. We were informed only minutes before boarding time of a delay despite the airlines knowing about the delay far earlier (the aircraft we would be taking arriving arrived and disembarked close to our boarding time, for all to see but AA still kept the original boarding time posted until last minute). Furthermore, once we boarded the taxi/wait time was also extended, with the pilot blaming “construction at SFO” for the delay, rather than taking accountability for the the plane’s late arrival coming into LAX. We took off approximately an hour later than scheduled. It’s for these reasons I adamantly avoid American Airlines when possible. Again, JAL was stellar.

Great service but food taste and options have gone down a few notches.

This airlines is always my favorite. Very consistent customer service and food is good. My last flight with them, I had no idea we landed because it was just that smooth of a land.

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.

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!

very nice experience…….we had a comfortable fly with emirates…this is 6 th time flying with emirates….i recommend friends to fly with emirates…….

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.

Boarding was terrible. My wife uses a wheel chair and she was in an incredibly hot closed metal cargo box for close to 20 minutes before getting on board

Only water and pretzels served on six hour flight. Did not see crew rest of flight. No video screens and so no wired audio. Poor sound on plan so did not understand anything said by crew. This is a safety issue. Electrical socket did not retain charging block so could not charge phone. No video screen so could not watch movies. Phone is not a substitute.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

I like the non stop flight to Lagos. The cabin crew were great, the food was alright and the ride was smooth. The downside is there wasn’t wifi connection from Lagos to Washington as stated. The 11hrs flight, became boring at times because of no wifi.

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.

they are improving. The crew from Charlotte to Tampa was outstanding. SMILING and trying to be helpful with the customers.

It was a flight operated by Aer Linus for BA and the plane and crew were very good but the food selection was average.

I like the food this time compared to my departure. I’m seated at the isle so it’s comfortable but I have to pay $124 for seat selection

Flight delayed an hour due to plane maintenance issues after getting in line to board. Issue was plane galley ovens which eliminated hot meals for overseas flight. Cold selections were limited due to availability. Drink and meal service (already an hour delayed) was very slow. Upon arrival in Nashville, had to sit at gate for about 15 minutes before disembarking with no explanation. Local police then boarded plane as we were disembarking so maybe that was the issue.

Leg space was not enough. The meal was not satisfactory.

Boarding good. Seats uncomfortable when lie flat. Food was awful. Tasted stale and chicken was dry. No live tv or flight map. Had to pay for internet.

Poor technical details on this plane. 1) There was no WiFi on an 8 hour long-haul flight. So no work could be done. That's below the standard expected for airlines these days. 2) The power outlet at my seat was busted and not working. 3) The headphone jack was loose and I had to keep adjusting my headphones to get good reception, or when it slipped out. - The flight was delayed to due mechanics. Sometimes this can't be avoided, I understand, and it's a big inconvenience to arrive that much later when traveling across time zones (then arriving at 4am from the prior time zone). - Also unique to this flight, the northern lights were visible on the right side of the aircraft, but I only found out after we landed (b/c again no wifi). I understand there are considerations about people being out of their seats to look, but I feel extremely disappointed and resentful that I wasn't told so that I could have a chance to look at this probably once-in-a-lifetime cosmic event from a view in the sky. - Flight crew was otherwise friendly and helpful.

I would have preferred something lighter for the second meal. Maybe a small sandwich .

They cancelled our flight the morning of departure at 4:30am.

Coach seats are too tight. Seem designed for small people. Food different but OK. Staff helpful.
