Not very comfortable seated in the back plane due to turbulence

I enjoyed flying on Korean Air. The service was great and the food was yummy, especially the bibimbap and cold spicy noodles. The only thing that bummed me out on this red-eye flight was that my seat did not properly recline so I was not able to sleep.

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

Crew was ok, but some passengers were a bit rude. Again, all outlets were not working, only the really slow charging usb plug on the entertainment system. Entertainment system was also bugged, some features just crash, the touch screen wasn't working and when trying to watch a movie the onscreen display kept flashing off and on making it very difficult to watch.

Korean Air had great service and the Bibimbap dish was the best airplane food I’ve ever had. It was a long flight so in between the two meals they served customers could get Shin ramen. The flight attendants let my children use a pair of nice headphones for the flight and had earbuds and slippers for all the adults. The flight was long but the time passed by relatively quickly because they have many great shows in their entertainment TV. I watched the BTS Love Yourself and Speak Yourself concerts 💜

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

Not accommodating ground staff On board slow service Crew members not very friendly

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.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

I cancelled the flights in good time but could only get a partial refund. I was not warned of this.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

One of the worst flight in business class by qatar airways and I’m no stranger with qatar airways businesses class, I travelled with the extensively in the past 12 years

Very comfortable flights. Not so many new releases in terms of films.

The aircraft was slightly newer but the food was very bad. Bland and uninteresting. Nothing special at all.

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

The crew were fine. I didn’t enjoy the food at all. I found it unappetising and really had trouble eating it. The comfort level was fine and our return flight is with Cathay Pacific but honestly I probably wouldn’t fly Cathay Pacific again.

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

It was good no problems made it on time for the next flight overseas!

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

The crew was fantastic and the over flight was perfect as well.

They shld provide food. Between food they are giving 10 hours gap which is toooo much

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

I had already opted for Vegan food before 2 months yet they say we have no record for it,
