The connection to the next flight can be difficult. We got lost in the Incheon Airport trying to transfer to Terminal 1, and almost missed our flight since it was very difficult to find instructions on how to get there. I suggest finding instructions how to transfer to the connecting flight in Incheon Airport.

Be careful to allow enough time when going thru Customs & Immigration. Despite having Global entry privileges, we missed our connecting domestic flight because luggages arrived late before we got thru Customs. Then, we have to contend with long security lines in SEA.

Fly Korean Air if you can. ICN is a great airport and you won't have any issues getting through in a reasonable time, but be aware that the gates for US-bound flights are fairly far away.

Incheon has always impressed me by its cleanliness so I invariably choose Korean Air over and above others. I appreciate the 2 free checked-in luggage policy. I find the weight limit for carry-ons plus personal item a bit restrictive. I bring a laptop with an AC adapter and that alone brings my carry-on weight close to the limit. Next time, I shall try not to bring other battery chargers (the ones that are not allowed to be checked in).

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.

There could have been better spacing of the passengers, it was crowded in some parts of the plane then other while rows were empty

Plane took off on time and I had the whole row to myself!

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.

This flight was a superior flight in all regards. Extremely pleasant experience.

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

The person in front of me was rude. He may came from some communism countries and don’t care of other people. No common manner and sense between human being.

Very nice staff, airplanes, and an excellent value in premium economy.

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.

As it's a budget airline it's pretty basic. But the quality of crew and plane is excellent.

First time flying with them and was pleasantly surprised. I had a premium economy seat which is very similar to some other airlines regional business class product. Seat was large, pillow was provided, huge amount of leg room, entertainment was available (only Korean shows), and lunch meal was served between Narita and Seoul. Really enjoyable and affordable

Maybe the reimbursement voucher should have been larger than a 10k won. That voucher is only for refreshments. The flight was delayed or pushed to more than 5 hours. It should be more than just 10k won and it was already past midnight. Some people or passengers like who was already there 5 hours prior to the original flight departure. 4pm** That was the only unfortunate thing about it . Other than that it was good .

5 hour delay, therefore, middle of the night arrival doesn’t help.

The customer service was excellent. They noticed that our connecting flight was scheduled too closely for us to complete customs, so they changed the flight. Our initial flight was delayed, and they were able to get us on another flight, all without charging us any additional fees. I would fly them again anytime!

Better screens, it would have been nice to have more comfortable seats.

Very clean ,flight attendants very professional,nice , Boarding was very easy

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

Love flying Asiana. Been using it for over a decade now.

Coming back to America was a peaceful flight everyone and everything was perfect

I had a bad experience coming from America to Thailand. On my connecting flight my check in suitcase was not put on the departing aircraft, I received my suitcase 24 hours after arriving in Bangkok and when I open my luggage my hand swelled up. The next morning when I put on an outfit from my suitcase my face swelled up and became numb. My entire vacation was ruined it seems that some kind of chemical was sprayed into suitcase and ruined my clothes and got me sick. The staff at my hotel called the airline and spoke to someone and they told me to file a complaint and gave my a website to do so. I did not file a complaint I felt like it would have fell on death ears. I had to throw away my brand new vacation clothes and suitcase and I had the worst vacation ever due to this happening to me.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

Flight was too cold. I wore a regular cotton tee and it wasn’t enough. It was a night time flight so I would have thought a blanket would be provided to passengers. A 4 hour flight and no options for a meal? I flew Asiana the next day from Seoul to Manilla. Same duration, 4 hours. They give everyone a pillow and blanket and serve a meal. Why is United so cheap and holding back meals and amenities? Also, they promote too much gay stuff and DEI in their advertisements. Please be mindful of other beliefs and don’t shove your gay ideology down my throat.

Staff always with a smile and very helpful with my mom who has mobility issues.

Was forced to check in my small carry on, even though I informed the crew it has very fragile items inside

This was one of the worst flights I’ve been on in years. I upgraded to comfort and had such an uncomfortable experience. The person next to me was oversized - which I understand - however, they took up their space and mine. I could only use about 50% of my seat space to not be physically touching this person the entire flight and there was no spatial awareness. I also could not use the seat outlet because their body was obstructing it. It was very inconvenient. Their body kept touching me repeatedly during the flight and I felt very uncomfortable. To pay more for an upgraded space and then not even being able to use it was highly disappointing.

No wheel chair as requested at Atlanta arrival on first flight.

Only freetext wifi was available in flight; browsing WiFi required payment. Since the seats had no in flight entertainment, Delta should revisit this policy on this longer flight.

Only water, tea or coffee served midflight, even to comfort seating. Man next to me needed two seats and took up a portion of my seat and Delta did nothing.

Flight was suspended mid air for over 1 hour and it was late

The flight was great as well as the airline staff

First class and monitors weren’t working for mine & my husbands. Eventually fixed, but quite annoyed as we bought first class. Also, No foot rests.

Prior to takeoff, the pilot told us there was a possibility of not being able to land and going to Portland. Well that happened, we took off and then did 8 loops around Spokane before the pilot told us we ran out of fuel and had to go to Portland. So for a 35 minute flight we have now been on the plane for 3 hours (boarded at 6:50 am and landed in Portland at 10:30). Then, we just sat in Portland's airport with no updates of when we can start heading back. All of a sudden, our pilots and crew just left, leaving us stranded in a different city and state. We continued to sit in Portland until we finally got a new crew assigned and boarded the plane (This was from 10:30-2). We then sat on the plane for an additional hour before take off because they had to count us multiple times. We finally landed in Spokane at 3:55 PM. So a flight that should have taken at max an hour took us 10 hours and we missed the majority of the recruiting event we went for.

It was delayed but other than that it was great.

Horrible Flight significantly delayed. Not due to united issue. But trying to rebook connection flight and get information about overnight accommodation was difficult. Agent did not seem to care or have any interest to help.

Everything was on time Will use united again for sure

Plane outlets in my row not working to charge phone. Staff response was, well it should be. Plug into seed for volume not working well. Had to find the sweet spot for plug in or it would shut off and on.

Fine not above and beyond as I had a connection that was delayed due to maintenance

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

Airport experience at Newark was not great. Only one gate open at immigration for US passports when multiple international flights arriving at the same time. Then having to take a train and a bus to different terminal only to have to clear security again, after I had already gone through at my initial departure location. Older plane, no entertainment screens available, and for economy plus, seat was very uncomfortable. Crew was friendly and this leg of my flight was on-time, even though I arrived later than initially scheduled due to 1st flight being over 2 hours delayed and missing my original connection.

I upgraded my seat and was promised it would be next to the emergency door for extra leg room and they said it was premium plus but it was at the back of the plane...same thing happened from Newark to Dubai

Everything except the food and entertainment. It was a great experience though

Bad food, bad service, cold cabin with no additional blankets when asked for (they told me they don’t provide additional blankets). I’m a frequent traveler and this is one of the worst companies I traveled with (by the way I thought that I booked my ticket with Lufthansa but I didn’t see that the flights were handled by United).

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.
