Verified travelerFlew with AIR PREMIA-Aug 2026
Get to the airport early. Put your items in the overhang, not under the chair. Do not plan on putting a bag under the seat in front of you; do not plan on needing anything out of that bag. You will not have room to grab it, even if you bring a thin drawstring bag. Anticipate there being no WiFi onboard.

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 was a comfortable flight and the flight crew were lovely!

Food was not great. Crew was lovely. There was no whisky on the first leg (BKK - ICN). And it took forever for my luggage to come out at LAX.

They let me board first because I'm a cancer patient & 75 years old. That was greatly helpful.

The crews were friendly, professional and courteous. Checking in was easy and smooth. The best part is, as we all know, the price.

Food quality is poor. Flight attendants are very friendly and professional.

I flew on Zip Air on the way to Asia so I can compare. The two airlines are night and day. Air Premia was so amazing compared to Zip Air. I have flown Korean Air in the past and I honestly don’t know the difference between Air Premia and the “non-budget” airlines. My Air Premia flight provided me two bags whereas I had to pay for Zip Air. On my under 11 hour flight, we were provided two full meals! The flight attendants were so kind and polite.

For the price, the overall experience was what I expected. The prices were fair and competitive, the staff friendly and more responsive than other airlines, and seating spacious. The downside was food portion size, but I'll gladly pay a few dollars more for the hot noodles or other supplemental snacks, given the more affordable ticket prices. I don't mind the absence of Hollywood movie programming if that leads to inflated ticket prices. Wi-Fi worked well. In addition to spacious seating for the Wide Premiium, I'd suggest foot rests to complement the calf rests. There're problems with booking Air Premia tickets at the home website. The underlying app engine won't process non-Korean credit cards, which is a major oversight, probably hurting the company's bottom line. I can go to Kayak or a third-party website to book Air Premia tickets, but it's an awkward work-around when other airlines don't have to resort to this tactic.

Most of them are OK! But, meals service was not enough. I felt hungry after eating the meal for the first time. I had to buy some other food. So I had to buy a sandwich and drinks for the return flight. And I am not sure it's only my feeling or not, I felt my butt is getting forward. I will use Korean Air or Asiana Airline for next time to visit Korea.

This form doesn’t work. Can’t type in, had to copy-paste. The crew constantly telling everyone about minor things is unnecessary. Did you put the belt on, push your bag more under the seat… The seat space was good for tall people, the food was decent for airplane.

Roomy seats for the given price! I couldn’t ask more!

I would have enjoyed some hot tea, preferably green tea, but they only serve hot coffee.

10 Hours delay on departure of the return flight and in-flight Wi-Fi was not available entire flying time all that caused monetary loss to my business.

It was a good flight, with great crew and service. I will definitely fly with them again. Excellent experience and very friendly. Excellent value.

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!

Even though the incoming flight was delayed by 20 minutes they managed to get us to SFO 15 minutes early.

Boarding, time to take off, in flight offerings, and staff were all great. I recommend using UA for this short flight.

Good experience. Staff was friendly and helpful. Flight was slightly delayed due to airport construction, but they still arrived on time.

This is the worst airline I’ve ever been on in my life and I’ve been probably on 75% of them. I said 15 years ago I would never go on United again. I was an idiot. I booked a flight with them from Las Vegas to San Francisco and of course they screwed that up and cost me a day flying all over the world trying to get to Thailand. My luggage was gone for 35 hours all because they couldn’t make their route on time

The flight out of Fresno boarded 1.5 hour past scheduled and made me miss my connecting flight from SFO to SEA.

My email and credit card were used fraudulently for this trip, so no, I did not take this flight.

Airplane is not very clean, food quality and taste was not good. Lufthansa used to be good but nowadays went down. Overall experience is just okay, wouldn't fly again, prefer Turkish airlines.

My experience was medium staff where great I dislike flying in triple 7 seats very uncomfortable and no room on jet all the rest of the flights where great

The crews are great.. Easy boarding. Inflight entertainment ok. Food is a disappointment.

There was no door or screen for privacy in Business class. With the price and class, the privacy is something the passengers expect. Understandably not all plane has the option but consider reconfiguration of the cabin. I would rather take other airlines in the future. The meal and snack options are different than what was in the website and printed information sheet. I also missed snacks but never offered again. It was not worth the price I paid.

$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.
