Lousy entertainment system. Crews are excellent. Meal is just mediocre.

Aircraft is pretty old. Seat is not comfortable. Meal quality is disappointing. Entertainment system is not impressive at all.

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.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

The tray table was broken and the food was terrible.

The gentleman at the gate I think his name is RIE was exceptional

While they turned off most cabin lights to allow people to sleep, I was bothered by how bright the side lights still were. It was still quite bright for me in a window seat, when I wish I could have slept!

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

No entertainment. Plane was so small had to pink tag a carry on ive used for 20 years easily on board. The fact the flight got in at midnight, had to wait for crew in fort wayne to allow the plane to approach the gate, THEN had to wait for bag on jet bridge made experience irritating at best.

Crew was great. Near on time departure and early arrival. Snacks are always meh. Not a fan of the "pay for everything including miles " proposal unless base flight rate going to be 100 bucks.

Would have been better if there was a nonstop flight from Tampa to Norfolk or Tampa to New Port News.

Overall Good! The weather delayed our takeoff from Atlanta and our arrival in Miami! If Mother Nature can mess up a flight she will do it every time!

The flight was smooth, the crew was great but the plane was quite old

Everything was great until I lost my water bottle and they can’t seem to locate it. I know I left it on the plane though.

After 3 hours of delays, they ended up cancelling my flight. And although I could purchase one-way tickets to get to my destination, they would not offer me these flights as compensation for the cancelled flight, and I didn't end up making it home until 13 hours after I was originally supposed to arrive. It made for an extremely strenuous end to an otherwise good trip.

Be careful about the bad policy and when purchasing seats

Very disappointed with premier lounge. Food selection very poor, both coffee machines out of order. For the price you charge for an upgrade, the seats don’t fully recline, movie selection is old. Not very good value. Asian airlines are light years ahead at a more affordable price.

The seat design in the premium economy section leaves virtually no room under the seat to store a bag or purse. Other than that, it was a great flight. Arrived early.

The flight was delayed, but not for weather. We landed over 3hrs later than planned.

The stag were helpful, kind and liked the passengers. The plane was pristinely clean! Great flight!

My flight was delayed more than once, but Air Canada updated us regularly. Friends on other airlines had much worse experiences.

My ticket did not exist when I got to the airport. I had to book another flight and was still charged by Kayak

Got denied my flight was told on Google that Air Canada was supposed to book me a flight back home because I never was able to go to my destination. They did not help me whatsoever. I had to book a whole new flight for that reason I would write this is zero

The plane was delayed an hour. Heard from other passengers that the Vancouver connection to SFO was never on-time.
