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

The boarding process for Korean airlines is very straightforward and easy. You've never met such helpful and friendly people. The food was great and the entertainment options were excellent too. My teenage boys found programs they wanted to watch while I had fun watching a full season of the Last Man - the Blind Investigator (Japanese), which my wife enjoyed too. My only complaint was that it takes a very long time to taxi at ICN (20 minutes) and the pilot had to hold at the gate for 10 minutes after our scheduled departure time, which meant we got to Seattle 27 minutes late. Luckily I had a long enough connection to make my next flight, but just barely.

It was about as poor as it could be!!! Delayed not once but multiple times

Flight there was massively delayed but never updated on the app. Flight home was massively delayed but also never reported until after we arrived at the airport.

The inside of the airplane was to cold and there was condensation dripping down on me. We were late taking off from Portland to Medford and I was miserable.

The flight left almost an hour and a half late because Alaska Airlines didn’t have anyone there who was qualified to drive or tow the airplane from its overnight parking spot to our gate. Because of that debacle, MANY passengers, including me, missed our connecting flights.

I have a good impression with the staff's friendliness and helpfulness and with the confort.

Several gate changes and then the plane kept getting delayed. The delay is understandable but this constant gate change I think twice or three times is just ridiculous.

Gated at different concourse than was supposed to be, with tight connexion

Flight was delayed over an hour. Flight attendant couldn’t get cc machine to work, so on board food was unavailable. Not Alaska’s finest day…

Alaska Airlines is a great airline. I had no idea. Lots of legroom.

Boarding was so bad in Seoul! Food was just junk!

I was impressed with how quickly the baggage transfers were made.

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

One of the best airlines that I flew on, the flight attendants were very attentive and professional.

Check in process was terrible. Lady at counter didn’t know what she was doing

They boarded very early. We rushed to transfer and got to the gate 5 minutes after boarding was scheduled to start, however they were making a last call and holding signs for “all customers” to board. They were helpful at the gate, but I was surprised to see that we were some of the last to board at 5 minutes after scheduled boarding was to begin.

The crew on this leg continue to be extremely helpful with my wife’s mobility issues. They also came by many many times to ensure we were comfortable and had drink some food.

The Pilot was one of the best I've had, very informative about turbulence and got us to our destination early

I liked the cleanness in the bathroom and good crew on board and at boarding gates. There was no Hindi (Bollywood) movies. The entertainment can be improved as it is one of the worst one I saw when I compared it with other airlines. The Mumbai to Amsterdam flight did not have any food for my family which does not contain eggs in it though we have selected “Hindu Asian vegetarian meal”

Friendly boarding crew. Better could have been a bit more substantial food for this 3 plus hour flight.

$2600 for the flight with food then not even a dog will eat specially breakfast

Flight attendants were ok. But it was a full flight.

The service was good ... I wondered if the stewardess was OK though as she seemed quite sad.

Terrible food, unprofessional flight attendants, and an uncomfortable seat. The food they provided was the worst I have ever had since I flew. They were worse than any cheap food you can get at convenience stores. A flight attendant talked to me in an insulting and demanding manner. If she wanted to say something, she should have said it professionally and kindly. No flight attendants served any drinks or snacks. If I needed a drink or snacks, I had to get up from my seat and go to the airplane's back area and serve myself. What were the flight attendants doing during their work shifts? A man sitting in front of me fully extended his chair to the back, so I had virtually no space to eat with reasonable comfort. Many people were so inconsiderate of others and fully extended their chairs to the back that they did not have enough space to eat. Flight attendants ignored these situations and never bothered to tell passengers to return their chairs to upright positions during the mealtime. I want to be comfortable and don't care if others feel uncomfortable because of me. Those were the dominant thoughts of people in that airplane. I paid more than $2000.00 for this terrible experience.

Very nice. Cabin crew is very attentive and professional. So nice!

Not allowing food choice through app. Very hard to find,

No pillow, blanket, or complimentary food provided on 5 hour flight

I had a great time flying with Air Canada on my 16+ hour journey over to Korea. The food was wonderful they had all kinds of options. Keep up the good work Air Canada I will most definitely fly with you again.

Food made me sick. There were delays on almost every flight.

The flight was delayed, gate crew gave confusing and contradictory instructions on where to queue.
