I like it when the plane have waited for passengers like us who are trying to catch the plane. Detroit was my mom's port of entry we spent too much time looking for our luggages at baggage claim which no problem. But then the problem occur after the immigration when the homeland security agents forgot to give us our passports which it took so long to find them and I was very anxious because we might not be able to catch our flights but luckily the plane to knoxville still sitting there and waiting for us. Praise the Lord for everything.

I took several flights that day, this was the only flight that was absolutely freezing!! It was so cold.

They changed aircrafts and they moved my seats that were already prepaid. I did not get the seats I paid for, so I got expensive seats that I didn't want

The flight was at least 3 hours late with not much of an explanation other than connecting flight was late

Good. Obviously there is a slightly condescending attitude of all American workers towards their customers but other than that all good.

Thanks for fixing the title of this question... the flight was a DELTA one marketed as a Korean Air flight. Which automatically makes it worse. The crew were actually rude in several cases and clearly lacked cultural sensitivity to the majority of the passengers (Koreans). This flight was also a minor heart attack before it started. Firstly, I thought I was buying a flight from Kayak, but it turns out they just acted as a front for this other company, UnderPricer, which took almost 24 hours to send a proper confirmation of the flight. We could not select the seats at checkout time either. We later submitted our seat selection to Korean Air, who proceeded to mess up the instructions to Delta, so our family was separated on the flight and our aisle seat was replaced with another middle seat.

It was a great experience in all aspects including passengers are respectful to each other. I will consider to fly with Korean Air again in the future.

It was a comfortable flight and the flight crew were lovely!

I won't hesitate to fly with Korean Air again and agian....if I can get a good deal.

The flight attendants seemed to be a little more grumpy this time. A350s could use more toilet stalls.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

It was terrible, I sat next to a person with a cat, I'm allergic to animal dander, my discomfort was extreme

Seats were really tight and the seat belts did not give enough slack.

Great list of movies, seat was generally comfortable, but not much shoulder room. The fresh baked cookie mostly made up for the lack of variety with the meals, which were all tomato based.

I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.
