The business class is excellent. I loved the food, and the crew was very attentive and professional. From boarding to arrival, everything felt smooth and well-organised.

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

Great service and comfort level. You can have more of vegetarian food options.

It’s great, long flight and arrive safe at destination

Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

I can't believe they put my wife and I in the two middle seats! It is a very long flight and we had single flyers on either side of us blocking the way to the bathroom! There's no reason to not give one of us the isle seat so we could have managed bathroom needs and snacks with convenience. So I think very poorly of Korean air to put us both in the middle, I've never had that happen before and will probably avoid this airline in the future because of this. We tried to have them change it but they didn't so you pretty much lost a customer because of it.

One of the flight attendants stepped on my foot. I was on the aisle seat. A lady inside needed to get out. So Instood. Just then, a flight attentendant came wuicklybtheoughbthe aisle and stepprd on my sock covered toes. I let out a small sound. She stopped momentarily, but didn’t ask how I was just took off of the aisle. Never came back to see how I was. Fortunately, I was not really hurt other than a slight soreness in my toes. But I found that to be very negligent.

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

Not very comfortable seated in the back plane due to turbulence

"The Room" is the only way to fly. The service was excellent and the stewardesses we all gorgeous and friendly. The boarding process was delayed and the attendants at the airport were not the best.

The flights with ANA were great. The flights with United, not so much.

Attendants were very kind and frequently offered water and snacks. Food was excellent. For some reason, my IFE system would not play dialogue for any media despite my efforts to change to different language voiceovers, restart the system, etc. so I could not watch any videos.

Staff at gate and crew on plane efficient and friendly.

As always, there is that one or two flight attendants that could be better.

It was good. The crew was efficient, food was good

Vegetarian options were not that great. However, the crew and service was awesome

Entertainment was good , comfort on airplane easy hoarding food and drinks was good and a friendly and good service of flight staff

I was good seat to keep stretch my legs . but couldn’t keep my bag in my hand . because they told me can’t keep my seat is no holder , because no seat fronts of us. wish I can put my leg on something higher. but instead of that everything goood.

Good airlines btu ORL airport messed up the return flight for me. Checking out a connecting flight pax is unacceptable.

Excellent service in business class. Well worth the slightly higher fare as it includes lounge access, additional luggage weight and a full hot meal on board.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

Need to improve on punctuality. My flight was delayed by 1 hour.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

The flight was mostly fine, but I really wished that seats had an outlet to charge devices considering the length of the flight (15 hours there and 14 hours back).

I give EVA 5 stars in every category. I enjoy this airline and it's great team of employees. I always highly recommend EVA to friends and family and everyone.

Requested an aisle seat at the gate and got it. The staff so friendly

My experience was very good. Everything was excellent except for the food. The food was mediocre. Not alot of options and the flavor was okay.

Flight was very delayed so I was able to get on an earlier flight via stand-by. Crew communicated effectively around delay and worked to make customers comfortable. Wifi was ok, streaming TV was great. App functionality broke down once I was moved to stand-by on earlier flight.

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

It was as good as it could be. Flying is not a pleasant experience these days.

The plane was very warm the entire time, despite my vents being open. Additionally, we didn't have internet on our personal devices

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

5 hour delay. They blamed the weather but it was the computer issues they had been dealing with for days.

Good. However the passenger in the search next to mine kept coughing. When we landed in Dallas we had to pick up.bags instead of going strait to the destination (which passengers do in Atlanta)

In between two meals period they're not providing something like banana / cup noodles or bugger. It's really fell sad that I was asking have to wait for 3 hours for second meal. (breakfast)

The crew are timely, friendly and professional. I was very impressed.

They overbooked the flight and reassigned my seat. To add insult they lied that my assigned seat was broken and promptly gave it to someone else

Jain veg meal I opted was super in taste but there was no sweet/desserts with it. I was a big missing in the meal...Please add some sweets to end the meal with 😊

The meat-and-rice combination was a good idea, but the food could use some improvement. The meat looked a bit mushy and almost like ground meat, which wasn’t very appetizing, and the flavor was just average. Other than that, everything else was great.

It is too long a flight to not have free access to internet. Should not charge. Should be some hours free.

The go to HK trip will easily giving jetlag, but coming back to Chicago has no jetlag because of the time taking off matter.

Just want to do a little more clean up so does not smell like urine.

Wanted different plane design with an additional bathroom at the back of the plane.
