Reviews of the top 4 airlines serving from South Korea to Washington
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.

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.
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.
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
I won't hesitate to fly with Korean Air again and agian....if I can get a good deal.
Will try never to fly Delta international again. Flight delayed and staff completely inept in dealing with it. Would not communicate, rude, completely disorganized. Once we reached Seoul the staff there had no idea what to do with us and led us around the airport from one pointless line to another. They were clearly not told how to manage the situation even though they had hours to make a plan. Never again.
lunch was good; breakfast was kinda meh cabin temprature was way too high new entertainment system but somewhat limited content
Going through security a second time to get on the next Korean Air flight was utterly ridiculous and unnecessary. We were in a International secure area.
Spokane airport was easy to get through. Seattle having my arrival and international departure gate so close to each other was fantastic!
I’m not much for Asian food. So did not eat much on the flight
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.
Great service. They could offer vegetarian food and do more to reduce waste.
Very comfortable seats, delicious meals, and friendly and helpful staff
Staff was excellent. Food could use more variety. -More vegetable options. Menu didn't have juice or soda listed. -The croissants were outstanding!
Asian Vegitarian food was test less No Salt or pepper served Need to improve with Chef who can caters for Peaple from India I am sure Chef knows different varieties of food Indian People like
Airfare was ok . Food not good , seat ok but not comfortable. Lay over too long , crew was ok Overall just ok
2 things that really tanked our experience with this trip with Asiana Airline (which used to be among my favorite airlines): 1) The "random" security screening at the boarding gate is crazily thorough (which is completely redundant to the security screening before we went through the security checkpoint before getting into the gate area), and the water was acquired inside of the gate area (from a lounge operated by the Inchon airport). We were asked to take out *EVERY* single items from the carry-on luggage and open up every comtainers / bags / packages to inspect. To add to it, there were two inspection workers there (one seemed to be a trainee and the other seemed to be a trainer), and the trainer worker held a very unfriendly / arrogant attitude towards us. As the youngest member (a minor) of my family was being "screened", the rest of my family wanted to make sure that no inappropriate actions would happen to her. That trainer worker yelled at us and attempted to use rude body language (waving her hands) and facial expression to ask us to stay away. 2) The luggage handling at the destination was really *REALLY* bad. Among my 25+ years of travel experiences, I'm going to have to say that this was the worst luggage experience where we didn't lose our luggage. Our flight was scheduled to land 12:45pm, and landed around 1pm. 15mins delay in landing is absolutely normal. Deplane process took a bit longer than usual flight (we waited for around 20mins, after arriving at the gate, before people were able to actually leave the plane). However, the luggage took another *2 HOURS* to arrive at the baggage claim carousel. This is insane. What's worse is, due to the delay in luggage, the flurry of passengers from our flight collided with 3 other incoming flights. The US border / custom line was like the longest Disneyland attraction line winding through the entire arrival hall and around all the baggage claim carousels (like at least a thousand people). I've never seen anything like that at SeaTec airport (US border control), period. The luggage claim experience really tanked our trust and overall impression for Asiana Airline's Seattle airport ground operational effectiveness and efficiency. This has to change in order for them to remain relevant / in-business with increased competitions from Korean Air and other Asia-based airlines.
Boarding was slow, but that was my fault for not getting in line sooner (missed the pre-boarding). Other than that everything was a 10!
My ticket was mistakenly not ticketed properly and I had to buy another ticket and you haven't reimburse me yet.
Good. But these constant surveys are becoming wearing. Buy a clue.
I did not feel secure that the staff knew all that they needed to, especially for securing the seats that I wanted for my next flights. However, they were friendly.
Service is always great with Alaska. Baggage services seems to be delayed in Seattle but Alaska airlines follows up with excellent customer service
Nice planes, Great crew. Ok snacks. One of the better airlines. Ok price.
It sucked. It was so warm the whole flight I had to use a cup of ice to cool me down. It was cramped and it smelled. There were screaming babies.
The people were great, the plugs were European with no adapters, and the snack was seven pretzel rods. The flight entertainment require the Wi-Fi that my browser couldn’t load.
Alaska Airlines is the absolute best. I am so pleased with their service and attention to detail. They are one of the last remaining airlines where you feel like a person rather than a herded animal. Thanks Alaska!
Boarding was so bad in Seoul! Food was just junk!
The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.
One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.
I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing
They did everything right and everything happened right on time.
Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).
Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.
Much better than I expected. I had an economy ticket so I was really happy the flight was so comfy and the service so generous. Passengers were all polite too.
Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.
It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.
Check in process was terrible. Lady at counter didn’t know what she was doing
