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.

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.
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.
It's good overall. Flight was packed. Inflight entertainment choices were lacking.
They were very accommodating of a dietary issue. Nice movie & tv selections. Non-stop helped get through a very long (15 hr) flight
Not very comfortable seated in the back plane due to turbulence
Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.
The aircraft was massive (A-380) and became crowded with 400+ passengers on board.
Coming back to America was a peaceful flight everyone and everything was perfect
Staff always with a smile and very helpful with my mom who has mobility issues.
The seats felt very small. We were supplied with pillows and blankets, which was nice. Lots of noise from the bathroom, plus exterior noise. Made it hard to hear the entertainment system, even using my own noise-cancelling headphones. The food was really bad. I generally request a vegetarian meal and one was supplied, but the pasta was cold and hard and there was nothing pleasant about it. Two meals were served on this flight; one was a repeat of the meal I had had on the flight immediately preceding this one, which was bad enough I didn't even try it. Drinks were very limited. All I wanted was water, and on a 10.5 hour flight, I was given 3 cups of about 3 ounces each.
We took business class, It was comfortable and I was able to sleep.
Great service. They could offer vegetarian food and do more to reduce waste.
Very comfortable seats, delicious meals, and friendly and helpful staff
The legroom in economy was better than other airlines. Since my legs are long, that means a lot. Also, the A380 from Los Angeles to Incheon gave passengers a smooth ride. Everything went smoothly from boarding to disembarkation in Incheon. I'd fly Asiana again!
Staff was excellent. Food could use more variety. -More vegetable options. Menu didn't have juice or soda listed. -The croissants were outstanding!
Anything to make the customer experience better. Stop cancelling flights like people traveling have nothing better to do than have their life plans halted. People go to great lengths to get time off work, make plans at the end of their flights, make travel plans, go through the nightmare of checking in at busy stressful airports, make pick up arrangements only to have the rug pulled out from under them. Flying has become so miserable now!! The flights were delayed ONLY with American Airlines. The disorganization is sickening. After the flight being delayed multiple times, when the flight was finally broadcast that it was a go, EXCEPT, they were now waiting for flight attendants. They had plenty of time to plan this, what the heck?! Missed both connecting flights because it was so delayed. I vowed to never fly American Airlines again, did it and BOY was it a mistake!!! American Airlines ranks with United as two worst airlines.
Potatoes were not cooked in the pork potato meal. Flight attendants were great in first class.
I paid extra to choose my seat. I chose a window seat. I don’t know if it was a disconnect between KAYAK or the airline but when we got to the airport, the seat was changed to a middle seat. Didn’t notice it til at the gate. I called wanted a refund and was told that I didn’t choose the seat even though on my KAYAK reservation it showed seat 12 A. So I paid extra for seat selection, but didn’t get it. And also did not get a refund. I specifically pay the extra for a seat selection. I normally am very happy with Alaska Airlines. They are usually in my top three of choices.
The plane smelled like an aquarium. Many passengers noted it smelled like fish. We then sat on the plane for over 2 hours before taking off
Worst travel day of my life. First bumped from our 7am flight—that we booked to ensure enough time to get to Chicago and get ready to go to a concert. Ended up on a flight 5hours later only to arrive in Chicago and spend 2 hours sitting in the tarmac. Missed the concert ($650 in tickets) and was too late to cancel the hotel ($500). I did receive a $200 voucher for the next Alaska ticket—soooo generous 👎. Would LOVE if Alaska reimbursed the $1000+that I am out!
Only issue is that when you board last they make you check your carry on due to lack of space. Did not care for that.
Great with American Poor with Alaska airlines. 3 hrs isn’t enough to transfer bags from one gate to another 5-6 gates away in the same terminal. Bags essential for cruise were unavailable Flights delayed cascading the problem. (Alaska Airlines responsibility). Very poor execution of operations that should be the simplest aspect of travel.
My flight was several times rescheduled and then finally canceled.
The flight kept getting delayed due to a maintenance issue. That happens, but there is no excuse for changing the gate FIVE TIMES, including one time nearly all the way across SeaTac. After we were delayed for 3+ hours, they did send us (via email) a $12 meal voucher...except you can't find a $12 meal anywhere in that airport, unless you consider a bag of M&M's and a bottle of water a meal. The plane had one problem after another but finally took off 4.5 hours late. This caused us to miss our hotel shuttle at ORD (they didn't run past midnight and it was 3 am) so we had to wait 25 minutes and pay for an Uber. I did get a $50 flight voucher from Alaska...big deal. Barely covers my Uber ride that I shouldn't have needed.
It was good. Too long for older people. Service and support was great! Friendly crew!
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
Got on the plane and sat there for an hour before departure.
Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.
Cramped seating for me. Luckily it wasn’t a long flight
Quinoa chocolate cookies are my favorite! Would be nice to have internet service like American
Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!
Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.
Legroom in Economy was fair to good. Seat was omay; I was hit in the shoulder twice by the cart as it was being whisked through the aisle. Overhead space was good for my carryon. Lighting environment was nice
We were delay because so many bags needed to be gate checked and it was disappointing not to have outlets in the seats for such a long flight.
Raleigh to Chicago was OK. The problem was Chicago to Lincoln. Flight was delayed 4 hours. Give them credit for the updates and reason why it was delayed
Comfortable seats and good crew. There should be some breakfast options in menu for economy class to purchase Wifi was not working in the flight
On time. Accommodated carry on and personal bag in the plane. Good entertainment available and access without using own device. Gave a whole can of juice rather than a pour. Seat did not recline much.
Good, our flight was delayed but that was totally out of their control due to weather and a presidential visit.
The price. Omg $1100. Was crazy and it was not clear on the website.
