Always on time and flight crew were great. Boarding in Manila was a bit chaotic and disorganized compared to Incheon.

Always on time and flight crew were great. Boarding in Manila was a bit chaotic and disorganized compared to Incheon.

Never had a flight delay issue with Korean Air, that's why I always go with this airline.

Flight crew were very attentive and made this trip a pleasure. Plus the fact that this our first time flying business class.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I normally love Korean Air, but this trip was not great. We boarded the plan and were settling into our seats. My son and I use these leg swings and we used it on the trip over to Cambodia, but on the way back the flight attendant very rudely told us we could not use it and that it was against regulations. I asked to see the regulation, but never saw it. The food on this trip was horrible as well, Even my son's kids meal was disgusting so we didn't eat anything on the flight. Thankfully we brought snacks. Entertainment - what happened to the games?

This was an amazing flight. The crew was great. The service was great. The food provided was great.

Seating was good in the economy with plenty of leg room. The seat cushions were a little firm though, especially for such a long flight. All meals were Korean as would be expected. The food was typical airline quality. Edible, but not something you would recommend to friends. Inflight entertainment was also all Korean but Korean tv and movies are made well and you can find something to watch. Just be prepared to read subtitles. Overall it was a good flight, especially for the price.

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 .

Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

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.

2nd major delay due to maintenance issues. 1st delay missed my connecting flight.

It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.

The plane hasnt left im stuck in seatle still my flight has been grounded for almost 5 hours

My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.

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

the crew cancel the morning service due to the weather. Then the flight got deverted to Nashville . we were on the ground for over two hours the only gave us water once... no food or any snacks.... the crew should have handled better and offered something to passengers.

My recent experience was excellent on Delta! I flew with Delta Comfort and I was really comfortable in my seat. I enjoyed the in-flight service. The flight attendants were so friendly and hospitable. I love the snack on the flight as well. This was my first time flying on Delta and I will definitely consider flying with them again.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

Mechanical Delay of over an hour with multiple gate changes. Entertainment system down for rejuvenation.

This was a Latam operated flight. Seats seemed a bit narrow in business class. Older aircraft.

I had a flight cancel and had it rerouted. When the rerouted they put me at a window seat instead of an isle. It was hard sitting by the window because the couple with masks on were making out. I get motion sickness which is why I need to have the isle seat.

NEVER MADE THE FLIGHT BECAUSE DELTA SAID THEY CAN NOT

THEY FAILED ME AND I NEVER GOT ON THE FLIGHT BECAUSE IT WAS SO DELAYED! I ENDED UP HAVING TO PAY OUT OF POCKET FOR A HOTEL AND STAY IN NASHVILLE TO CATCH A FLIGHT FOR THE FOLLOWING DAY. DELTA IS POOR CUSTOMER SERVICE>

8 hours late and the plane smelled like urine, that smell in the morning when your child wet the bed in the night.

Didn't make the flight because the first leg of my flight was canceled and the next leg was already booked.

My flight was canceled a few hours before boarding. I was rebooked on Copa airlines and missed an important meeting .

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

Experience was great - no complaints. Took off on time, landed early. Got to the gate relatively quickly - took a little bit of extra time to deplane but nothing excessive.

Business class seats felt very cramped compared to other airlines.

Economy plus was so cramped I could not use my laptop. It was beyond bad.

OK, we were delayed and had to de plane and reboard.

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

Both my flight where delayed Had 25min to make it to my transfer flight
